For patients diagnosed with lumbar central canal stenosis with asymptomatic foraminal stenosis (FS), surgeons occasionally only decompress central stenosis and preserve asymptomatic FS. These surgeries have the potential risk of converting preoperative asymptomatic FS into symptomatic FS postoperatively by accelerating spinal degeneration, which requires reoperation. However, little is known about delayed-onset symptomatic FS postoperatively. This study aimed to evaluate the rate of reoperation for delayed-onset symptomatic FS after lumbar central canal decompression in patients with preoperative asymptomatic FS, and determine the predictive risk factors of those reoperations. This study is a retrospective cohort study. Two hundred eight consecutive patients undergoing posterior central decompression for lumbar canal stenosis between January 2009 and June 2014 were included in this study. The number of patients who had preoperative FS and the reoperation rate for delayed-onset symptomatic FS at the index levels were the outcome measures. Patients were divided into two groups with and without preoperative asymptomatic FS at the decompressed levels. The baseline characteristics and revision rates for delayed-onset symptomatic FS were compared between the two groups. Predictive risk factors for such reoperations were determined using multivariate logistic regression and receiver operating characteristics analyses. Preoperatively, 118 patients (56.7%) had asymptomatic FS. Of those, 18 patients (15.3%) underwent reoperation for delayed-onset symptomatic FS at a mean of 1.9 years after the initial surgery. Posterior slip in neutral position and posterior extension-neutral translation were significant risk factors for reoperation due to FS. The optimal cutoff values of posterior slip in neutral position and posterior extension-neutral translation for predicting the occurrence of such reoperations were both 1 mm; 66.7% of patients who met both of these cutoff values had undergone reoperation. This study demonstrated that 15.3% of patients with preoperative asymptomatic FS underwent reoperation for delayed-onset symptomatic FS at the index levels at a mean of 1.9 years after central decompression, and preoperative retrolisthesis was a predictive risk factor for such a reoperation. These findings are valuable for establishing standards of appropriate treatment strategies in patients with lumbar central canal stenosis with asymptomatic FS. Copyright © 2017 Elsevier Inc.

Feigel, Amanda; Sylla, Patricia

2016-01-01

Laparoscopy has become widely accepted as the preferred surgical approach in the management of benign and malignant colorectal diseases. Once considered a relative contraindication in patients with prior abdominal surgery (PAS), as surgeons have continued to gain expertise in advanced laparoscopy, minimally invasive approaches have been increasingly incorporated in the reoperative abdomen and pelvis. Although earlier studies have described conversion rates, most contemporary series evaluating the impact of PAS in laparoscopic colorectal resection have reported equivalent conversion and morbidity rates between reoperative and non-reoperative cases, and series evaluating the impact of laparoscopy in reoperative cases have demonstrated improved short-term outcomes with laparoscopy. The data overall highlight the importance of case selection, careful preoperative preparation and planning, and the critical role of surgeons' expertise in advanced laparoscopic techniques. Challenges to the widespread adoption of minimally invasive techniques in reoperative colorectal cases include the longer learning curve and longer operative time. However, with the steady increase in adoption of minimally invasive techniques worldwide, minimally invasive surgery (MIS) is likely to continue to be applied in the management of increasingly complex reoperative colorectal cases in an effort to improve patient outcomes. In the hands of experienced MIS surgeons and in carefully selected cases, laparoscopy is both safe and efficacious for reoperative procedures in the abdomen and pelvis, with measurable short-term benefits.

From 1958 to 1992, 105 patients were operated for discrete (or membranous) subaortic stenosis (DSAS). Our surgical techniques changed during this period. Before 1980 DSAS was removed by a sharp excision leaving the part on the mitral valve untouched (n = 58). After 1980 blunt dissection was used to enucleate DSAS completely (n = 47). The operation for DSAS was combined with aortic valve replacement (AVR) in 7 instances. Follow-up with recent echo-Doppler studies was complete in 100 patients. Recurring or persisting DSAS led to reoperation in 17 patients. Sixteen of them had had sharp, incomplete resections. One patient from the group of complete blunt enucleations was reoperated on twice. The interval between the first operation and the first reoperation averaged 9.7 years (range: 1-33 years). Nine reoperated patients had AVR. The risk factors for AVR were older age at first operation or late reoperation. In our early experience five patients died after operation. Another three patients died following one or more reoperations. Blunt dissection never led to complete AV block. It follows the anatomical cleavage planes and always allowed for complete and safe removal of DSAS. Although the follow-up is shorter, blunt enucleation thus far has had a lower incidence of reoperation.

Epilepsy surgery is the most efficacious therapeutic modality for patients with medically refractory focal epilepsies, but surgical failures remain a challenge to the epilepsy treatment team. The aim of present study was to evaluate the postoperative outcome of patients who underwent reoperation after a failed epilepsy surgery on the temporal lobe. We systematically analyzed the results of comprehensive preoperative evaluations before the first surgery, and before and after reoperation in 17 patients with drug resistant temporal lobe epilepsies. Overall, 13 of 17 patients (76.5%) improved after reoperation: five patients (29.4%) were completely seizure free after reoperation (median duration 60months, range 12-72); six patients (35.3%) were seizure free at least 12month before observation points (median duration 120.5months, range 35-155) and two patients (11.8%) had a decrease in seizure frequency. Four patients (23.5%) remained unchanged with respect to seizure frequency and severity. There was no correlation between the improvement in seizure outcome after reoperation and other clinical data except of the history of traumatic brain injury (TBI). The patients who had no history of TBI improved after reoperation, compared to patients with TBI (p=0.044). The postoperative seizure outcome of patients with incongruent Video-EEG results before the first surgery (p=0.116) and before reoperation (p=0.622) was not poorer compared to patients with congruent Video-EEG results. Reoperation can considerably improve the operative outcome of the first failed epilepsy surgery in patients with drug resistant temporal lobe epilepsies. Epilepsy centres should be encouraged to report the results of failed epilepsy surgeries. Copyright © 2012 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

Purpose Perianal lesions are common in Crohn disease, but their clinical course is unpredictable. Nevertheless, predicting the clinical course after surgery for perianal Crohn disease (PCD) is important because repeated operations may decrease patient's quality of life. The aim of this study was to predict the risk of reoperation in patients with PCD. Methods From September 1994 to February 2010, 377 patients with PCD were recruited in twelve major tertiary university-affiliated hospitals and two specialized colorectal hospitals in Korea. Data on the patient's demographics, clinical features, and surgical outcomes were analyzed. Results Among 377 patients, 227 patients were ultimately included in the study. Among the 227 patients, 64 patients underwent at least one reoperation. The median period of reoperation following the first perianal surgery was 94 months. Overall 3-year, 5-year, and 10-year cumulative rates of reoperation-free individuals were 68.8%, 61.2%, and 50.5%, respectively. In multivariate analysis (Cox-regression hazard model), reoperation was significantly correlated with an age of onset less than 20 years (hazard ratio [HR], 1.93; 95% confidence interval [CI], 1.07-3.48; P = 0.03), history of abdominal surgery (HR, 1.99; 95% CI, 1.08-3.64; P = 0.03), and the type of surgery. Among types of surgery, fistulotomy or fistulectomy was associated with a decreased incidence of reoperation in comparison with incision and drainage (HR, 0.19; 95% CI, 0.09-0.42; P < 0.001). Conclusion Young age of onset and a history of abdominal surgery were associated with a high risk of reoperation for PCD, and the risk of reoperation were relatively low in fistulotomy or fistulectomy procedures.

The aim of the present nationwide Danish cohort study was to examine the association between body mass index (BMI) and reoperation in patients who are sur-gically treated for perforated peptic ulcer (PPU). This was a nationwide cohort study of all Danish patients who were surgically treated for benign gastric or duodenal PPU between 2011 and 2013. reoperation within 30 days of the primary surgical procedure and 90-day survival. The association between BMI and reoperation are presented as crude and adjusted odds ratios (OR) with 95% confidence intervals (CIs). A total of 726 patients were included. The median age was 69.5 years (range: 18.2-101.7 years), 51.4% were women (n = 373), 78.4% (n = 569) of the patients had at least one co-existing disease, and 47.5% (n = 345) were categorised as American Society of Anesthesiologists (ASA) class ≥ 3. Re-operative surgery was done in 124 patients (17.1%). No statistically significant adjusted association between underweight, overweight or obesity and re-operation was found (adjusted OR (95% CI): 0.456 (0.181-1.148), 1.468 (0.857-2.517), and 1.314 (0.663-2.601), respectively). Patients undergoing reoperative surgery had a statistically significantly lower crude 90-day survival than patients without need of reperative surgery; 63.9% (83/124) versus 75.9% (457/602), p = 0.037. In the present nationwide cohort study of PPU patients, no statistically significantly adjusted correlation between BMI and re-operation rates was found. Patients undergoing reoperative surgery had a decreased 90-day survival. not relevant. not relevant.

Reoperations account for >10% in pediatric epilepsy surgery cohorts, and they are especially relevant in young children with catastrophic epilepsy. To determine surgical outcomes and their predictive factors in reoperations for refractory epilepsy in childhood. We retrospectively analyzed presurgical findings, resections, and outcomes of 23 consecutive children who underwent reoperations from 2000 to 2011. Etiology included cortical dysplasia with/without glioneuronal tumor in 19 patients (83%), sole glioneuronal tumor in 2, and tuberous sclerosis and Rasmussen encephalitis in 1 each. The reasons for the failure of the initial surgery were functional considerations in 8 (35%), incorrect delineation of the epileptogenic zone in 8 (35%), and resection not performed as initially planned in 7 (30%) cases. Final procedures included 8 (35%) intralobar, 8 (35%) multilobar resections, and 7 (30%) hemispherotomies. Following reoperations, 14 (61%) patients were seizure free, 6 (26%) showed significant or worthwhile improvement, and 3 (13%) did not respond to surgery. Six of 8 patients who underwent the first resection before the age of 3 years, 6 of 8 whose first resection was limited by functional considerations, and all 7 with hemispherotomy as the final resection achieved seizure freedom after reoperation. Reoperation is particularly beneficial for selected children with refractory epilepsy associated with cortical dysplasia that did not respond to an initial limited and/or early resection but achieved seizure freedom after extensive procedures. When indicated, reoperation should be performed at the youngest possible age to profit from higher functional plasticity in compensating for neurological deficit.

National population-based cohort study. To compare the reoperation rates between cervical spondylotic radiculopathy and myelopathy in a national population of patients. There is an inherently low incidence of reoperation after surgery for cervical degenerative disease. Therefore, it is difficult to sufficiently power studies to detect differences between reoperation rates of different cervical diagnoses. National population-based databases provide large, longitudinally followed cohorts that may help overcome this challenge. We used the Korean Health Insurance Review and Assessment Service national database to select our study population. We included patients with the diagnosis of cervical spondylotic radiculopathy or myelopathy who underwent anterior cervical discectomy and fusion from January 2009 to June 2014. We separated patients into two groups based on diagnosis codes: cervical spondylotic radiculopathy or cervical spondylotic myelopathy. Age, sex, presence of diabetes, osteoporosis, associated comorbidities, number of operated cervical disc levels, and hospital types were considered potential confounding factors. The overall reoperation rate was 2.45%. The reoperation rate was significantly higher in patients with cervical spondylotic myelopathy than in patients with cervical radiculopathy (myelopathy: P = 0.0293, hazard ratio = 1.433, 95% confidence interval 1.037-1.981). Male sex, presence of diabetes or associated comorbidities, and hospital type were noted to be risk factors for reoperation. The reoperation rate after anterior cervical discectomy and fusion was higher for cervical spondylotic myelopathy than for cervical spondylotic radiculopathy in a national population of patients. 3.

New techniques for preoperative localization of nonpalpable breast lesions may decrease the reoperation rate in breast-conserving surgery (BCS) compared with rates after surgery with the standard wire-guided localization. However, a valid reoperation rate for this procedure needs to be established for comparison, as previous studies on this procedure include a variety of malignant and benign breast lesions. To determine the reoperation rate after wire-guided BCS in patients with histologically verified nonpalpable invasive breast cancer (IBC) or ductal carcinoma in situ (DCIS) and to examine whether the risk of reoperation is associated with DCIS or histologic type of the IBC. This nationwide study including women with histologically verified IBC or DCIS having wire-guided BCS performed between January 1, 2010, and December 31, 2013, used data from the Danish National Patient Registry that were cross-checked with the Danish Breast Cancer Group database and the Danish Pathology Register. Reoperation rate after wire-guided BCS in patients with IBC or DCIS. Wire-guided BCS was performed in 4118 women (mean [SD] age, 60.9 [8.7] years). A total of 725 patients (17.6%) underwent a reoperation: 593 were reexcisions (14.4%) and 132 were mastectomies (3.2%). Significantly more patients with DCIS (271 of 727 [37.3%]) than with IBC (454 of 3391 [13.4%]) underwent a reoperation (adjusted odds ratio, 3.82; 95% CI, 3.19-4.58; P < .001). After the first reexcision, positive margins were still present in 97 patients (16.4%). The risk of repeated positive margins was significantly higher in patients with DCIS vs those with IBC (unadjusted odds ratio, 2.21; 95% CI, 1.42-3.43; P < .001). The risk of reoperation was significantly increased in patients with lobular carcinoma vs those with ductal carcinoma (adjusted odds ratio, 1.44; 95% CI 1.06-1.95; P = .02). A total of 202 patients (4.9%) had a subsequent completion mastectomy, but no difference was found in the type of reoperation between patients with DCIS and those with IBC. A lower reoperation rate after wire-guided BCS was found in this study than those shown in previous studies. However, the risk of reoperation in patients with DCIS was 3 times higher than in those with IBC. The widespread use of mammographic screening will increase the number of patients diagnosed with DCIS, making a precise localization of nonpalpable DCIS lesions even more important.

Some hip fracture patients need one or more reoperations because of complications following initial operative treatment. The aim of this study was to identify all further surgical interventions in a cohort of patients with hip fractures over a period of 8 years after index fracture. Immediate direct costs of these reoperations were also calculated. This retrospective study investigated 221 consecutive patients with hip fractures operated on at two different hospitals in southeastern Finland. The study period in hospital A was from 1 February 2003 to 31 January 2004, and in hospital B from 1 February 2003 to 30 April 2004. About 50% were femoral neck fractures, 41% trochanteric fractures, and 9% subtrochanteric fractures. Patients' medical records were checked from the hospital records and confirmed manually. Short- and long-term complications were recorded. Survival analysis was performed using a life-table method. The actual costs for reoperations and other further procedures for each patient were calculated using diagnosis-related groups-based costs for both hospitals in 2012. A total of 20 patients (9%) needed reoperations. Overall, 10 patients (8.9%) with a femoral neck fracture (n = 112), 8 patients (8.7%) with trochanteric fracture (n = 92), and 2 patients (10.5%) with subtrochanteric fracture (n = 19) were reoperated on. The median interval between the primary operation of the acute hip fracture (n = 20) and the first reoperation was about 300 days (range: 2 weeks to 82 months). Among the women reoperated on, the excess mortality was lower than among those undergoing a single operation. The median costs of treatment per patient with one or more reoperations were €13,422 in hospital A (range: €1616-€61,755), €11,076 in hospital B (range: €1540-€17,866), and €12,850 in the total study group (p = 0.43). In the case of infections (3 patients), the mean costs per patient were €28,751 (range: €11,076-€61,755). Almost 10% of hip fracture patients required reoperations, and these reoperations caused significant direct costs to health care. However, direct costs account for only approximately 25% of the first year's total costs. These costs should be taken into account when evaluating the economics of hip fractures and the burden of health care.

Operative fixation of displaced, mid-shaft clavicle fractures has become an increasingly common practice. With this emerging trend, data describing patient outcomes with longer follow-up are necessary. We retrospectively reviewed the medical records of subjects treated with plate fixation for displaced mid-shaft clavicle fractures from 2003 to 2009 at a Level I trauma hospital. All subjects were greater than 12 months post-index surgery. Treatment involved ORIF with either a low-contact dynamic compression plate (LCDC) or a contoured plate (pre-contoured or pelvic reconstruction plate). Our primary outcome was reoperation for any indication. 143 subjects were included. The mean age was 36 ± 14 years and the mean time to reoperation or chart review was 33 months. Contoured plates were used in 64% of cases and LCDC plates were used in the remaining subjects. Twenty-nine subjects (20%) underwent reoperation: 23.5% of subjects treated with LCDC plates and 18.5% of subjects treated with contoured plates (p=0.52). Indications for reoperation included implant irritation (n=25), implant failure (n=2), and non-union (n=2). There was near statistically significant association with reoperation and female gender (p=0.05) but no association between reoperation and age (p=0.14), fracture class (p=0.53), plate type (p=0.49), or plate location (p=0.93). The mean QuickDASH score for the population surveyed was 8.8 (5.5-12.1; 95% CI) with near statistically significant and clinically relevant difference between those considering reoperation and those not 22.3 (8.6-36.0; 95% CI) versus 6.7 (3.6-9.8; 95% CI). This study represents a large series of displaced clavicle fractures treated with open reduction and plate fixation. Reoperation following plate fixation is relatively common, but primarily due to implant irritation. No difference in reoperation rates between plate types or location could be detected in our current sample size. Also, excellent functional outcomes continue to be observed several years after clavicle fracture fixation. Copyright © 2014 Elsevier Ltd. All rights reserved.

Abstract The aim of this study is to investigate the incidence of unplanned reoperations from all causes due to bleeding in neurosurgical patients. The medical records of patients who received neurosurgical procedures at our hospital were retrospectively reviewed and data of patients who received reoperations were extracted and summarized. A literature review was conducted of the Medline, Cochrane, EMBASE, and Google Scholar databases up to November 2013. The main outcome measure was the rate of unplanned reoperations due to bleeding. At our hospital, 68 patients with a mean age of 41.5 ± 21.5 years (range, 7 months to 76 years) received an unplanned reoperation. More than 70% of the patients were older than 18 years, 64.7% were males, and 94.1% had cranial surgery. Almost 60% of the patients received >1 blood transfusion (58.8%) after the first surgery. Of the 68 patients, 35 (51.5%) received a second operation due to bleeding. Univariate logistic regression analysis only showed that an increasing time interval between the first and second surgery was associated with a decreased chance of the reoperation being performed due to bleeding (odds ratio [OR] = 0.843, 95% confidence interval [CI]: 0.720–0.987; P = .033). Of 229 studies identified, 5 retrospective reports with a total of 1375 patients were included in the analysis. The rate of reoperations for bleeding in the 5 studies ranged from 4.2% to 31.5%. Employing measures to reduce postoperative bleeding may help reduce the rate of unplanned neurosurgical reoperations. PMID:26061301

2015-01-01

The purpose of this systematic review is to collate results of studies comparing fixed and mobile bearing unicompartmental knee arthroplasty (UKA), focusing on complications and timing for reoperations. Out of 723 results derived from PubMed, EMBASE and Cochrane database search engines on bearings in arthroplasty, 10 studies comparing clinical results of fixed bearings to mobile bearings in UKA were found eligible for analysis. The reoperation rate was calculated using a novel method such as reoperations per hundred component years, and the causes of specific reoperations were investigated. The overall reoperation rate per hundred component years was similar between the mobile bearings (1.392) and fixed bearings (1.377); however, mobile bearings were more susceptible to reoperations in cases with aseptic loosening (0.393>0.255), progression of arthritis (0.428>0.357) and implant dislocation (0.286>0). The overall incidence of complications is similar for fixed and mobile bearing designs in UKA. The discussion on complications presented above may assist surgeons in their choice of bearing design.

Up to 18% of patients undergoing antireflux operations will require reoperation. Authors caution that with each additional reoperation, fewer patients achieve satisfaction. The quality of life in patients who underwent revision operations was compared with patients who underwent primary antireflux operations to determine the effectiveness of revision operations. We retrospectively reviewed patients who underwent revision after failed antireflux operations from 2004 to 2014. Patients were divided into two groups: first reoperation (Reop[1]) and more than one reoperation (Reop[>1]). For comparison, a control group of patients who underwent primary antireflux operations was included. Patients underwent quality of life assessment preoperatively and postoperatively. We identified 105 reoperative patients: 94 Reop(1), 11 Reop(>1), and 112 controls. The primary reason for failure was combined fundoplication herniation and slippage. Morbidity, mortality, and readmission rates were similar in all groups. Postoperative outcomes were improved in all groups but to a lesser degree in subsequent reoperations. Gastroesophageal Reflux Disease Health-Related Quality of Life: controls, 20.0 to 2.0; Reop(1), 26.5 to 4.0; and Reop(>1), 13.0 to 2.0. Quality of Life in Reflux and Dyspepsia: controls, 4.5 to 7.0; Reop(1), 3.7 to 6.7; and Reop(>1), 3.5 to 5.8. Dysphagia Severity Score: controls, 44.0 to 45.0; Reop(1), 36.0 to 45.0; and Reop(>1), 30.8 to 45.0. Patients undergoing revision antireflux operations have improved quality of life, relatively normal swallowing, and primary symptom resolution at a median of 20 months postoperatively. However, patients who undergo more than one reoperation have lower quality of life scores and less improvement in dysphagia, suggesting that other procedures such as Roux-en-Y or short colon interposition, should be considered after a failed initial reoperation.

Little is known about the choice of reoperation after failed fundoplication for gastroesophageal reflux disease. Both redo fundoplication and conversion procedure to Roux-en-Y gastric bypass (RYGB) are safe and effective. We aimed to characterize the rates of different revisional procedures and to identify risk factors associated with failed fundoplication. Using a statewide database, we examined records for patients who underwent fundoplication between 2000 and 2010. The primary outcomes were the rate of each type of reoperation and the pattern of subsequent procedures. Demographics and comorbidities were used in a multivariable logistic regression model to identify risk factors associated with reoperation after fundoplication. A total of 9462 patients were included. Overall, 430 (4.5%) patients underwent reoperation. Of those, 46 (10.7%) patients underwent RYGB at first reoperation, with the remainder having a redo fundoplication. An additional five patients were converted to RYGB after undergoing a redo fundoplication (51 total patients converted to RYGB at any point, 11.9%). Eighty-three percent of patients converted to RYGB were obese, as opposed to 8% for redo fundoplication. A single redo fundoplication was done in 81% of patients, while 35 patients (8.1%) underwent two or more revisional procedures. On average, any reoperation was performed 2.9 years after fundoplication, with redo fundoplication 2.5 years and RYGB 6.5 years later. Age 30-49 years (vs. >70 years; OR 2.01, p = 0.011) and 50-69 years (vs. >70 years; OR 1.61, p = 0.011), female gender (OR 1.56, p = < 0.0001), and chronic pulmonary disease (OR 1.40, p = 0.0044) were associated with revisional surgery. Fundoplication has a low reoperation rate within a mean 8.3 years of follow-up. Redo fundoplication is more commonly performed and at an earlier point than conversion to RYGB. Younger age, female gender, and chronic pulmonary disease are associated with reoperation after fundoplication.

This study aims to describe laparoscopic reoperation (LSR) and compare its outcomes with transabdominal reoperation (TAR) for treating Hirschsprung's disease (HD). Eighteen patients with HD underwent reoperation for recurring constipation due to residual aganglionosis and transition zone pathology after an initial transanal procedure (LSR, n=10; TAR, n=8). Preoperative, operative and postoperative data were collected through patient follow-ups ranging from 13 to 75months to compare operative characteristics and postoperative outcomes between the two groups. Ten patients underwent laparoscopic reoperation in our institution without major complications. On average, blood loss was significantly lower in the LSR group (mean±standard deviation, 83±32.7mL) than in the TAR group (185±69mL) (P=0.001). The LSR group had a shorter hospitalization time (12±2days) than the TAR group (15±2.1days) (P=0.02). There was no statistically significant difference in incidence of postoperative complications between the two groups. LSR is safe and technically feasible in HD for recurring constipation due to residual aganglionosis and transition zone pathology, when initial transanal procedure fails. Although RA and TZP can be cured by reoperation, great efforts should be made to diminish the necessity of reoperation. Copyright © 2015 Elsevier Inc. All rights reserved.

Three NOD2/CARD15 gene variants (3020insC, R702W, G908R) have been identified as genetic risk factors for Crohns disease patients. However the diagnostic and therapeutic relevance for clinical practice remains limited. The aim of this study was to evaluate the association between these variants, the risk of reoperation and disease phenotype. In 76 Crohns disease patients (41 female, 35 male) with a minimum 5 year follow-up, three polymorphisms of the NOD2/CARD15 gene (R702W, G908R, 3020insC) were tested. Detailed clinical and medical history including surgical procedures and reoperations were obtained by reviewing the medical charts and completed prospectively. Association between the need for reoperation, disease phenotypes and gene variants were analyzed. 24 patients (32%) showed at least one NOD2/CARD15 mutation. 25 patients (33%) required reoperation, 51 (67%) represented the control group. The expected trend that patients with NOD2/CARD15 variants have a higher frequency of reoperations was not confirmed to a level of statistical significance (p=0.2688). Two of the four patients (50%) with the 3020insC variant required further surgery. We did not confirm any association between NOD2/CARD15 mutations and age at diagnosis (p=0.4356), behavior (p=0.6610), or localization (p=0.4747) according to the Montreal classification. NOD2/CARD15 polymorphisms did not significantly affect the reoperation rate. Homozygosity for the 3020insC variant in the NOD2/CARD15 gene is associated with a high risk of reoperation. NOD2/CARD15 gene variants are not significantly associated with specific disease phenotypes.

Persistent or recurrent radicular pain after lumbosacral spine surgery is often associated with nerve root compression and is treated by repeated operation or, as a last resort, by spinal cord stimulation (SCS). We conducted a prospective, randomized, controlled trial to test our hypothesis that SCS is more likely than reoperation to result in a successful outcome by standard measures of pain relief and treatment outcome, including subsequent use of health care resources. For an average of 3 years postoperatively, disinterested third-party interviewers followed 50 patients selected for reoperation by standard criteria and randomized to SCS or reoperation. If the results of the randomized treatment were unsatisfactory, patients could cross over to the alternative. Success was based on self-reported pain relief and patient satisfaction. Crossover to the alternative procedure was an outcome measure. Use of analgesics, activities of daily living, and work status were self-reported. Among 45 patients (90%) available for follow-up, SCS was more successful than reoperation (9 of 19 patients versus 3 of 26 patients, P <0.01). Patients initially randomized to SCS were significantly less likely to cross over than were those randomized to reoperation (5 of 24 patients versus 14 of 26 patients, P=0.02). Patients randomized to reoperation required increased opiate analgesics significantly more often than those randomized to SCS (P <0.025). Other measures of activities of daily living and work status did not differ significantly. SCS is more effective than reoperation as a treatment for persistent radicular pain after lumbosacral spine surgery, and in the great majority of patients, it obviates the need for reoperation.

Detection of occult pericardial hemorrhage early after open-heart surgery using technetium-99m red blood cell radionuclide ventriculography

Pericardial or mediastinal hemorrhage requiring reoperation occurs in 2% to 5% of patients, usually early (0 to 48 hours), after open-heart surgery. This hemorrhage may be occult, and resulting cardiac tamponade may easily be misinterpreted as ventricular dysfunction, common early postoperatively. In such cases, appropriate and timely intervention may not occur. Of 50 patients evaluated by technetium-99m red blood cell gated equilibrium radionuclide ventriculography (RNV) because of early postoperative cardiogenic shock of uncertain etiology, 17 had unique scintigraphic images suggestive of intrathoracic hemorrhage. Of these 17, 5 had a generalized halo of abnormal radioactivity surrounding small hyperdynamic right and leftmore » ventricles, 11 had localized regions of intense blood pool activity outside the cardiac chambers (two with compression of single chambers), and one demonstrated marked radionuclide activity in the right hemithorax (2000 ml of blood at reoperation). Twelve patients had exploratory reoperation for control of hemorrhage as a direct result of the scintigraphic findings, three were successfully treated with fresh frozen plasma and platelet infusions along with medical interventions to optimize cardiac performance, and two patients died in cardiogenic shock (presumed tamponade) without reoperation. In the 12 reoperated patients, all were confirmed to have active pericardial bleeding. Scintigraphic localization of abnormal blood pools within the pericardium corresponded to the sites at which active bleeding was witnessed at reoperation. The abnormal bleeding was etiologically related to the tamponade state, with marked improvement in hemodynamics after reoperation. Nine additional patients were reoperated for presumed tamponade after RNV revealed an exaggerated halo of photon deficiency surrounding the cardiac chambers.« less

Surgical management of spontaneous subclavian thrombosis due to venous thoracic outlet syndrome (vTOS) results in durable relief of symptoms. The need to reoperate is rare. We report our experience with reoperation for vTOS. Patients evaluated for vTOS between 1996 and 2016 were identified in a prospective database. Data recorded included demographics, initial presentation, initial surgery, recurrent presentation, reoperation, and final outcomes. In all, 261 patients were evaluated for vTOS, of these, 246 patients underwent first rib resections. Ten (3.8%) patients required evaluation for recurrent vTOS symptoms. Prior management included thrombolysis (4) and anticoagulation alone (6). Prior surgical approaches included infraclavicular (2), supraclavicular (2) and transaxillary (6). One operation was complicated by a hemothorax, and one a brachial plexus injury. Indication for reoperation included congestive symptoms (6) and recurrent thrombosis (4). Evaluation included chest X-rays (10), venogram (8), intra-venous ultrasound (2), and computed tomography venography (3). Significant compression by remaining rib segments were identified in all: inadequate resection of the anterior first rib (7), inadequate resection of posterior rib segment (1), and erroneous resection of second rib (2). Reoperations include 7 transaxillary approaches, 1 medial claviculectomy, and 1 paraclavicular decompression. One phrenic nerve palsy occurred following paraclavicular decompression. All underwent postoperative venography and angioplasty. At final evaluation, 8 veins are patent and congestive symptoms resolved, and 1 crushed stent could not be reopened despite decompression. The incidence of reoperation for first rib resection in cases of vTOS is low and appears largely due to missteps during the initial operation. Awareness of potential errors including inadequacy of resection, intraoperative disorientation, and misunderstanding of the limitations of surgical approaches will result in fewer reoperations.

Repair for a small (≤ 2 cm) umbilical and epigastric hernia is a minor surgical procedure. The most common surgical repair techniques are a sutured repair or a repair with mesh reinforcement. However, the optimal repair technique with regard to risk of reoperation for recurrence is not well documented. The aim of the present study was in a nationwide setup to investigate the reoperation rate for recurrence after small open umbilical and epigastric hernia repairs using either sutured or mesh repair. This was a prospective cohort study based on intraoperative registrations from the Danish Ventral Hernia Database (DVHD) of patients undergoing elective open mesh and sutured repair for small (≤ 2 cm) umbilical and epigastric hernias. Patients were included during a 4-year study period. A complete follow-up was obtained by combining intraoperative data from the DVHD with data from the Danish National Patient Register. The cumulative reoperation rates were obtained using cumulative incidence plot and compared with the log rank test. In total, 4,786 small (≤ 2 cm) elective open umbilical and epigastric hernia repairs were included. Age was median 48 years (range 18-95 years). Follow-up was 21 months (range 0-47 months). The cumulated reoperation rates for recurrence were 2.2 % for mesh reinforcement and 5.6 % for sutured repair (P = 0.001). The overall cumulated reoperation rate for sutured and mesh repairs was 4.8 %. In conclusion, reoperation rate for recurrence for small umbilical and epigastric hernias was significantly lower after mesh repair compared with sutured repair. Mesh reinforcement should be routine in even small umbilical or epigastric hernias to lower the risk of reoperation for recurrence avoid recurrence.

OBJECTIVE Although epilepsy surgery is an effective treatment option, at least 20%-40% of patients can continue to experience uncontrolled seizures resulting from incomplete resection of the lesion, epileptogenic zone, or secondary epileptogenesis. Reoperation could eliminate or improve seizures. Authors of this study evaluated outcomes following reoperation in a pediatric population. METHODS A retrospective single-center analysis of all patients who had undergone resective epilepsy surgery in the period from 2001 to 2013 was performed. After excluding children who had repeat hemispherotomy, there were 24 children who had undergone a second surgery and 2 children who had undergone a third surgery. All patients underwent MRI and video electroencephalography (VEEG) and 21 underwent magnetoencephalography (MEG) prior to reoperation. RESULTS The mean age at the first and second surgery was 7.66 (SD 4.11) and 10.67 (SD 4.02) years, respectively. The time between operations ranged from 0.03 to 9 years. At reoperation, 8 patients underwent extended cortical resection; 8, lobectomy; 5, lesionectomy; and 3, functional hemispherotomy. One year after reoperation, 58% of the children were completely seizure free (International League Against Epilepsy [ILAE] Class 1) and 75% had a reduction in seizures (ILAE Classes 1-4). Patients with MEG clustered dipoles were more likely to be seizure free than to have persistent seizures (71% vs 40%, p = 0.08). CONCLUSIONS Reoperation in children with recurrent seizures after the first epilepsy surgery could result in favorable seizure outcomes. Those with residual lesion after the first surgery should undergo complete resection of the lesion to improve seizure outcome. In addition to MRI and VEEG, MEG should be considered as part of the reevaluation prior to reoperation.

The Ross operation is the operation of choice for children who require aortic valve replacement (AVR) and may also provide a good option in selected adult patients. Although the autograft does not require anticoagulation and has a superior haemodynamic profile, concern regarding autograft and allograft longevity has risen. In this light, we report the 13-year results of our prospective autograft cohort study. Between 1988 and 2005, 146 consecutive patients underwent AVR with a pulmonary autograft at Erasmus Medical Center Rotterdam. Mean age was 22 years (SD 13; range 4 months-52 years), 66% were male. Hospital mortality was 2.7% (N = 4); during follow-up four more patients died. Thirteen-year survival was 94 +/- 2%. Over time, 22 patients required autograft reoperation for progressive neo-aortic root dilatation. In addition, eight patients required allograft reoperation. Freedom from autograft reoperation at 13 years was 69 +/- 7%. Freedom from allograft reoperation for structural failure at 13 years was 87 +/- 5%. Risk factors for autograft reoperation were previous AVR and adult patient age. Although survival of the Rotterdam autograft cohort is excellent, over time a worrisome increase in reoperation rate is observed. Given the progressive autograft dilatation, careful follow-up of these patients is warranted in the second decade after operation.

This study was performed to determine the clinical results of patients with Crohns disease who require surgical resection. The outcome of patients undergoing initial surgery was compared with those having reoperation. One hundred sixty-four patients undergoing intestinal resection for Crohns disease at The Mount Sinai Hospital from 1976 to 1989 were studied prospectively. The mean duration of follow-up was 72 months. Ninety patients (55%) underwent initial intestinal resection whereas 74 patients (45%) underwent reoperation for recurrent disease. Patients undergoing reoperation were older (33.4 vs. 38.7 years), had longer durations of disease (8.7 vs. 15.2 years), had shorter resections (60 vs. 46 cm), and were more likely to require ileostomy. Forty-seven percent of the patients with multiple previous resections required an ileostomy. This group also received a mean of 2.3 U blood in the perioperative period and showed a trend to increased symptomatic recurrence (49% vs. 71% at 5 years). Patients with Crohns disease undergoing first and second reoperation have outcomes similar to those in patients undergoing primary resection. Patients requiring multiple reoperations are more likely to require blood transfusions and permanent ileostomy and to show a greater trend to early symptomatic recurrence.

Heller myotomy for achalasia is associated with a recurrence rate of around 10%, thus reoperative surgery is often necessitated. This paper aims to review the available literature on laparoscopic reoperation for achalasia in order to assess its feasibility and effectiveness. A Medline, Embase, Ovid, Cochrane database and Google(TM) Scholar search was performed with the following Mesh terms: "laparoscopic", "redo", "reoperative", "Heller's", "esophagomyotomy" and "achalasia". Outcomes of interest included patient demographics and details of primary procedure, operative details, intra- and post operative complications and symptom scores. Seven studies reported outcomes from 54 cases. Conversion occurred in 7% (4/54) of cases. Thirteen percent (7/54) of patients sustained intra-operative gastric or oesophageal perforation; however these were all noted and repaired intra-operatively leading to no subsequent morbidity. No deaths were reported. Pre- and post operative symptom scores were heterogeneous, however did appear to improve after the procedure. This review demonstrates that laparoscopic reoperation for achalasia is feasible and safe with complication rates comparable to the primary laparoscopic operation. It is recommended that laparoscopic reoperative Heller's myotomy should only be performed by surgeons with special interest in oesophagogastric surgery and adequate experience in laparoscopic surgery for achalasia.

We have analysed the predictors of postoperative complications and the need for reoperation after grafting of the alveolar cleft from one specialised cleft centre. The data were obtained from hospital casenotes of patients operated on from December 2004 to April 2010, with a minimum one-year follow-up from the final operation. Independent variables included postoperative complications and the need for reoperation. Conditional variables were sex, age, type of cleft, sides affected, donor area, type of graft material, and the presence of an erupted tooth in contact with the cleft. A total of 71 patients had bone grafted on to the alveolar cleft. The following associations were found to be significant: postoperative complications and need for reoperation (p=0.003); age and complications (p=0.002); affected side and complications (p=0.006); age and reoperation (p=0.000); sex and reoperation (p=0.001); and type of cleft and reoperation (p=0.001). Proper attention should be given to all the variables and risk factors to overcome the many obstacles that might have an adverse influence on a successful outcome of alveolar bone grafting for patients with clefts.

2015-03-01

Surgery for perforated peptic ulcer (PPU) is associated with a risk of complications. The frequency and severity of reoperative surgery is poorly described. The aims of the present study were to characterize the frequency, procedure-associated risk and mortality associated with reoperation after surgery for PPU. All patients treated surgically for PPU in Denmark between 2011 and 2013 were included. Baseline and clinical data, including 90-day mortality and detailed information on reoperative surgery, were collected from the Danish Clinical Register of Emergency Surgery. Distribution frequencies of reoperation stratified by type of surgical approach (laparoscopy or open) were reported. The crude and adjusted risk associations between surgical approach and reoperation were assessed by regression analysis and reported as odds ratio (OR) with 95 per cent c.i. Sensitivity analyses were carried out. A total of 726 patients were included, of whom 238 (32·8 per cent) were treated laparoscopically and 178 (24·5 per cent) had a laparoscopic procedure converted to laparotomy. Overall, 124 (17·1 per cent) of 726 patients underwent reoperation. A persistent leak was the most frequent cause (43 patients, 5·9 per cent), followed by wound dehiscence (34, 4·7 per cent). The crude risk of reoperative surgery was higher in patients who underwent laparotomy and those with procedures converted to open surgery than in patients who had laparoscopic repair: OR 1·98 (95 per cent c.i. 1·19 to 3·27) and 2·36 (1·37 to 4·08) respectively. The difference was confirmed when adjusted for age, surgical delay, co-morbidity and American Society of Anesthesiologists fitness grade. However, the intention-to-treat sensitivity analysis (laparoscopy including conversions) demonstrated no significant difference in risk. The risk of death within 90 days was greater in patients who had reoperation: crude and adjusted OR 1·53 (1·00 to 2·34) and 1·06 (0·65 to 1·72) respectively. Reoperation was necessary in almost one in every five patients operated on for PPU. Laparoscopy was associated with lower risk of reoperation than laparotomy or a converted procedure. However, there was a risk of bias, including confounding by indication. © 2015 BJS Society Ltd Published by John Wiley & Sons Ltd.

The primary aim of this study was to define the standard minimum follow-up required to produce a reliable estimate of the rate of re-operation after radial head arthroplasty (RHA). The secondary objective was to define the leading reasons for re-operation. Four electronic databases, between January 2000 and March 2017 were searched. Articles reporting reasons for re-operation (Group I) and results (Group II) after RHA were included. In Group I, a meta-analysis was performed to obtain the standard minimum follow-up, the mean time to re-operation and the reason for failure. In Group II, the minimum follow-up for each study was compared with the standard minimum follow-up. A total of 40 studies were analysed: three were Group I and included 80 implants and 37 were Group II and included 1192 implants. In Group I, the mean time to re-operation was 1.37 years (0 to 11.25), the standard minimum follow-up was 3.25 years; painful loosening was the main indication for re-operation. In Group II, 33 Group II articles (89.2%) reported a minimum follow-up of < 3.25 years. The literature does not provide a reliable estimate of the rate of re-operation after RHA. The reproducibility of results would be improved by using a minimum follow-up of three years combined with a consensus of the definition of the reasons for failure after RHA.

To determine the relationship between abduction deficit and reoperation among patients with infantile esotropia (IET). The records of 216 patients (432 eyes) with IET who underwent surgery, from 2010 to 2015 were studied. Patients with IET whose deviation appeared before 6mo of age and had stable preoperative deviation in two examinations with at least 2wk apart and a minimum 3mo postoperative follow up were included. Cases with early onset accommodative esotropia, congenital cataract, retinopathy of prematurity (ROP), manifest nystagmus, fundus lesions, neurologic and ophthalmic anomalies, 6 th nerve palsy and Duane's syndrome were excluded. Preoperative abduction deficit was considered from -1 to -3 grading scale. Three months after surgery, children were classified into no-need reoperation [deviation≤15 prism diopters (PD)], and need-reoperation groups (deviation>15 PD). In this retrospective study, 117 female and 99 male patients with the mean surgical age of 4.7±6.4y were included. Reoperation rate was 33.3% and 16.0% in IET patients with and without abduction deficit, respectively in patients who had a history of late surgery. Abduction deficit increased the odds of reoperation by 82% [OR=1.82, 95% confidence interval (CI) =1.05 to 3.19, P =0.003] in patients who had a history of late surgery (>2 years old, P =0.021). Abduction deficit was improved significantly after operation ( P <0.001). Based on our results, abduction deficit can be considered as a risk factor of reoperation in IET patients who are operated at the age of more than 2y.

The objective of this independent study is to determine the impact of recombinant human bone morphogenetic protein 2 (rhBMP-2) on reoperation for pseudarthrosis and/or instrumentation failure. A nested case-control study of first-time posterolateral, instrumented fusion of the lumbar spine for degenerative spinal disease was undertaken. Cases of reoperation for pseudoarthrosis and/or instrumentation failure were assigned to controls, who did not experience the primary outcome measure at the time of reoperation. Cases and controls were matched on number of interspaces fused and inclusion of interbody. Predictors of reoperation for pseudoarthrosis and/or instrumentation failure were assessed with a conditional logistical regression controlling for rhBMP-2, age, obesity, and smoking. Of the 448 patients, 155 cases of reoperation for pseudoarthrosis and/or instrumentation were matched with 293 controls. Twenty-six percent of first-time surgeries included rhBMP-2, which was statistically more commonly used in the control cohort (33.11%) versus the case cohort (12.90%) (Unadjusted odds ratio [ORunadj]=0.28) (95% confidence interval [CI]: 0.16-0.49). Following a multivariate analysis controlling for age, obesity, and smoking, the rhBMP-2 recipients incurred a 73% lower odds of reoperation for pseudoarthrosis and/or instrumentation failure (95% CI, 0.15-0.48). Neither sarcomatous nor osseous neoplasm was detected in the study population. Mean follow up did not differ between the cases (81.57±standard deviation [SD] 4.98months) versus controls (74.75±2.49month) (ORunadj=1.01) (95% CI: 1.00-1.01). rhBMP-2 in lumbar fusion constructs protects against reoperation for pseudoarthrosis and/or instrumentation failure. However, the decision to include fusion supplements should be weighted between surgical determinants and clinical outcomes. Copyright © 2016 Elsevier Ltd. All rights reserved.

To determine the extent to which knowledge from clinical trial protocols is transferred to nonparticipating patients. Retrospective review of prospectively collected data from a large clinical trial. Six level-1 international trauma centers. We compared rates and timing of reoperation in a subset of patients enrolled in the Study to Prospectively evaluate Reamed Intramedullary Nails in Patients with Tibial Fractures (SPRINT) to concurrent patients who were eligible but not enrolled. This was a retrospective review of prospectively collected trial data. The records of 6 of the original SPRINT centers were searched for non-SPRINT patients who underwent intramedullary nailing of a closed tibial fracture. The rate and timing of reoperation were compared. A P < 0.05 was considered significant. One hundred fourteen non-SPRINT patients were compared with 328 patients enrolled in SPRINT from those same sites. There were 7 reoperations (6.1%) in non-SPRINT patients versus 18 (5.2%) in SPRINT patients [odds ratio (OR) 1.19, 95% confidence interval (CI) 0.41 to 3.13; P = 0.811]. There was no difference in the time to reoperation between the SPRINT and non-SPRINT patients (6.2 vs. 6.8 months, 95% CI of the difference -3.8 to 2.6; P = 0.685) or in the proportion of patients who underwent reoperation before 6 months (29% vs. 43%; OR 1.75; 95% CI 0.18 to 15.41; P = 0.647). Patients not enrolled in SPRINT had similarly low rates of reoperation for nonunion, and the average time to reoperation for both groups was longer than 6 months. A 6-month waiting period may have allowed slow-to-heal fractures adequate time to heal, thereby reducing the rate of diagnosis of nonunion. As such, this waiting period could contribute to lower-than-expected reoperation rates for nonunion. It is possible that clinical trials may beneficially influence the care of nonenrolled patients.

It is interesting to review the topic of reoperative surgery from the aspect of cost-effectiveness or, worse yet, profitability for either the institution or surgeon. The majority of the published material focuses on indications, risk factors, and short- and long-term outcomes. The context of the discussion is framed by the question "Can you make money doing reoperative surgery?" The short answer is that if this is all you do, probably not. Few, if any, publications assess the impact a redo procedure has on the factors that directly affect the fee schedule: surgeon time consumption (intraoperative and postoperative), stress (physical and psychological), and malpractice effects. Far more work needs to be done to understand the cost and resource consumption effects of major reoperative surgery.

Anterior cervical discectomy and fusion is a standard surgical treatment for cervical radiculopathy and myelopathy, but reoperations sometimes are performed to treat complications of fusion such as pseudarthrosis and adjacent-segment degeneration. A cervical disc arthroplasty is designed to preserve motion and avoid the shortcomings of fusion. Available evidence suggests that a cervical disc arthroplasty can provide pain relief and functional improvements similar or superior to an anterior cervical discectomy and fusion. However, there is controversy regarding whether a cervical disc arthroplasty can reduce the frequency of reoperations. We performed a meta-analysis of randomized controlled trials (RCTs) to compare cervical disc arthroplasty with anterior cervical discectomy and fusion regarding (1) the overall frequency of reoperation at the index and adjacent levels; (2) the frequency of reoperation at the index level; and (3) the frequency of reoperation at the adjacent levels. PubMed, EMBASE, and the Cochrane Register of Controlled Trials databases were searched to identify RCTs comparing cervical disc arthroplasty with anterior cervical discectomy and fusion and reporting the frequency of reoperation. We also manually searched the reference lists of articles and reviews for possible relevant studies. Twelve RCTs with a total of 3234 randomized patients were included. Eight types of disc prostheses were used in the included studies. In the anterior cervical discectomy and fusion group, autograft was used in one study and allograft in 11 studies. Nine of 12 studies were industry sponsored. Pooled risk ratio (RR) and associated 95% CI were calculated for the frequency of reoperation using random-effects or fixed-effects models depending on the heterogeneity of the included studies. A funnel plot suggested the possible presence of publication bias in the available pool of studies; that is, the shape of the plot suggests that smaller negative or no-difference studies may have been performed but have not been published, and so were not identified and included in this meta-analysis. The overall frequency of reoperation at the index and adjacent levels was lower in the cervical disc arthroplasty group (6%; 108/1762) than in the anterior cervical discectomy and fusion group (12%; 171/1472) (RR, 0.54; 95% CI, 0.36-0.80; p = 0.002). Subgroup analyses were performed according to secondary surgical level. Compared with anterior cervical discectomy and fusion, cervical disc arthroplasty was associated with fewer reoperations at the index level (RR, 0.50; 95% CI, 0.37-0.68; p < 0.001) and adjacent levels (RR, 0.52; 95% CI, 0.37-0.74; p < 0.001). Cervical disc arthroplasty is associated with fewer reoperations than anterior cervical discectomy and fusion, indicating that it is a safe and effective alternative to fusion for cervical radiculopathy and myelopathy. However, because of some limitations, these findings should be interpreted with caution. Additional studies are needed. Level I, therapeutic study.

To compare selected outcomes (30-day reoperation and total length of hospital stay) following emergency appendectomy between populations from New York State and England. This retrospective cohort study used demographic and in-hospital outcome data from Hospital Episode Statistics (HES) and the New York Statewide Planning and Research Cooperative System (SPARCS) administrative databases for all patients aged 18+ years undergoing appendectomy between April 2009 and March 2014. Univariate and adjusted multivariable logistic regression were used to test significant factors. A one-to-one propensity score matched dataset was created to compare odd ratios (OR) of reoperations between the two populations. A total of 188,418 patient records, 121,428 (64.4%) from England and 66,990 (35.6%) from NYS, were extracted. Appendectomy was completed laparoscopically in 77.7% of patients in New York State compared to 53.6% in England (P < 0.001). The median lengths of hospital stay for patients undergoing appendectomy were 3 (interquartile range, IQR 2-4) days versus 2 (IQR 1-3) days (P < 0.001) in England and New York State, respectively. All 30-day reoperation rates were higher in England compared to New York State (1.2 vs. 0.6%, P < 0.001), representing nearly a twofold higher risk of 30-day reoperation (OR 1.88, 95% CI 1.64-2.14, P < 0.001). As the proportion of appendectomy completed laparoscopically increased, there was a reduction in the reoperation rate in England (correlation coefficient -0.170, P = 0.036). Reoperations and total length of hospital stay is significantly higher following appendectomy in England compared to New York State. Increasing the numbers of appendectomy completed laparoscopically may decrease length of stay and reoperations.

Reoperation and readmission are often avoidable, costly, and difficult to predict. We sought to identify risk factors for readmission and reoperation after spine surgery and to use these factors to develop a scoring system predictive of readmission and reoperation. The National Surgical Quality Improvement Project database for years 2012 to 2014 was reviewed for patients undergoing spinal surgery, and 68 perioperative characteristics were analyzed. A total of 111,892 patients who underwent spinal surgery were identified. The rate of reoperation was 3.1%, the rate of readmission was 5.2%, and the occurrence of either was 6.6%. Multivariate analysis found 20 perioperative factors significantly associated with both readmission and reoperation. Preoperative and operative factors found significant included age >60 years, African-American race, recent weight loss, chronic steroid use, on dialysis, blood transfusion required, American Society of Anesthesiologists classification ≥3, contaminated wound, >10% probability of experiencing morbidity, and operative time >3 hours. Postoperative associations identified included urinary tract infection, stroke, dehiscence, pulmonary embolism, sepsis, septic shock, deep and superficial surgical site infection, reintubation, and failure to wean from ventilator. An unweighted and weighted risk score were generated that yielded receiver operating characteristic curves with areas under the curve of 0.707 (95% confidence interval [CI]: 0.701-0.713) and 0.743 (95% CI: 0.736-0.749) 0.708 (95% CI: 0.702-0.715), respectively. Patients with an unweighted score ≥7 had a more than 20-fold increased risk of reoperation or readmission and a more than 1000-fold increased risk of mortality than did patients with a score of 0.

Refractory bleeding after complex cardiovascular surgery often leads to increased length of stay, cost, morbidity, and mortality. Recombinant activated factor VII administered in the intensive care unit can reduce bleeding, transfusion, and surgical re-exploration. We retrospectively compared factor VII administration in the intensive care unit with reoperation for refractory bleeding after complex cardiovascular surgery. From 1501 patients who underwent cardiovascular procedures between December 2003 and September 2007, 415 high-risk patients were identified. From this cohort, 24 patients were divided into 2 groups based on whether they either received factor VII in the intensive care unit (n = 12) or underwent reoperation (n = 12) for refractory bleeding. Preoperative and postoperative data were collected to compare efficacy, safety, and economic outcomes. In-hospital survival for both groups was 100%. Factor VII was comparable with reoperation in achieving hemostasis, with both groups demonstrating decreases in chest tube output and need for blood products. Freedom from reoperation was achieved in 75% of patients receiving factor VII, whereas reoperation was effective in achieving hemostasis alone in 83.3% of patients. Prothrombin time, international normalized ratio, and median operating room time were significantly less (P < .05) in patients who received factor VII. Both groups had no statistically significant differences in other efficacy, safety, or economic outcomes. Factor VII administration in the intensive care unit appears comparable with reoperation for refractory bleeding after complex cardiovascular surgical procedures and might represent an alternative to reoperation in selected patients. Future prospective, randomized controlled trials might further define its role. Copyright © 2011 The American Association for Thoracic Surgery. Published by Mosby, Inc. All rights reserved.

The survival of patients with congenital heart disease has increased in the recent years, because of enhanced diagnostic capabilities, better surgical techniques, and improved perioperative care. Many patients will require reoperation as part of staged procedures or to treat grafts deterioration and residual or recurrent lesions. Reoperations favor the formation of cardiac adhesions and consequently increase surgery time; however, the impact on morbidity and operative mortality is certain. The objective of the study was to describe the risk factors for mortality in pediatric patients undergoing a reoperation for congenital heart disease. Historic cohort of patients who underwent reoperation after pediatric cardiac surgery from January 2009 to December 2015. Operations with previous surgical approach different to sternotomy were excluded from the analysis. In seven years, 3,086 surgeries were performed, 481 were reoperations, and 238 patients fulfilled the inclusion criteria. Mean number of prior surgeries was 1.4 ± 0.6. Median age at the time of reoperation was 6.4 years. The most common surgical procedures were staged palliation for functionally univentricular heart (17.6%). Median cross-clamp time was 66 minutes. Younger age at the moment of resternotomy, longer cross-clamp time, and Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery Congenital Heart Surgery (STAT) Mortality Categories risk category greater than three were risk factors for mortality. The number of resternotomies was not associated with mortality. Mortality prior to hospital discharge was 4.6%, and mortality after discharge but prior to 30 days after surgery was 0.54%. Operative mortality was 5.1%. Resternotomy in pediatric cardiac surgery is a safe procedure in our center.

The Ross operation: a 12-year experience.

PubMed

Elkins, R C

1999-09-01

The Ross operation, originally introduced as a scalloped subcoronary implant with an 80% survival and 85% freedom from reoperation, has recently been modified to a root replacement which is now the most utilized implant technique. The mid and late results of this operative technique and comparison of intra-aortic implants and root replacement in a single institution are reported. The records of 328 patients who had a Ross operation at the University of Oklahoma (August 1986 to July 1998) were reviewed to assess operative technique and patient-related factors on survival, autograft valve function, homograft valve function, valve-related complications, and need for reoperation. Operative survival was 95.4% with an actuarial survival of 89% +/- 5% at 8 years. Freedom from replacement of the pulmonary autograft was 94% +/- 3% at 8 years, freedom from reoperation on the pulmonary homograft was 90% +/- 4% at 8 years, and freedom from autograft valve reoperation or dysfunction (3+ autograft valve insufficiency) was 83% +/- 6% at 9 years. The incidence of autograft valve reoperation and late autograft valve dysfunction was decreased by root replacement. Annulus reduction and fixation improved early results in patients with aortic insufficiency and annulus dilatation. Early results have been excellent, as the development of late autograft valve dysfunction or dilatation has been rare. The excellent hemodynamic results with a limited incidence of reoperation and replacement of the autograft valve justify its continued use.

Background Papillary thyroid carcinoma (PTC) has excellent survival, yet recurrence remains a challenge. We sought to determine the proportion of re-operations performed for persistent, rather than truly recurrent disease. Methods We conducted a retrospective review of a prospectively maintained database. Patients with PTC that had re-operation for disease from 2000–2016 were included. We defined recurrence as disease that developed after a patient had an undetectable thyroglobulin and negative ultrasound within one year of surgery. Results A total of 69 patients underwent 92 re-operations. On initial pathology: mean tumor size was 2.6cm; 50.7% were multifocal; and 42% had extra-thyroidal extension. Half (46%) of the patients underwent a central/lateral neck dissection at initial surgery and 76.8% were treated with post-operative radioactive iodine. The median time to first re-operation was 21 months (range, 1–292), and 41.8% occurred within 1 year. Only three operations met criteria for true “recurrence”, while 71 operations were categorized as persistence. Conclusion Many re-operations for PTC are for management of persistent disease. Over half of the patients required re-operation within the first two years, which strongly suggests that improvements in the pre-operative assessment and adequacy of initial surgery need to be made to improve the care of patients with thyroid cancer.

To define the factors predisposing to recurrence and evaluate the results of reoperations for achalasia. We reviewed the medical records of ten patients (4 men and 6 women; mean age, 51.5 ± 11.0 years), who underwent reoperations for achalasia between August 1994 and August 2010. The primary surgical procedures were Heller-Dor (HD) cardioplasty in nine patients and Heller myotomy in one patient. The factors contributing to failure of the primary operation included inadequate myotomy (n = 2), recurrent adhesion after myotomy (n = 2), reflux esophagitis (n = 2), difficulty in passage caused by tortuosity of the esophagus (n = 2), difficulty in passage through the thoracic esophagus (n = 1), and severe chest pain (n = 1). The reoperations included repeated HD procedures (n = 4), repair of an esophageal hiatal hernia (n = 2), thoracic esophageal myotomy (n = 2), straightening of the lower esophagus with gastropexy (n = 1), and subtotal esophagectomy (n = 1). The success rate of the reoperations for resolving symptoms was 90 % (9 patients). Selecting surgical procedures based on the causes and conditions of recurrence led to symptomatic improvement and acceptable outcomes.

A small number of patients fail fundoplication and require reoperation. Laparoscopic techniques have been applied to reoperative fundoplications. We reviewed our experience with reoperative laparoscopic fundoplication. Reoperative laparoscopic fundoplication was undertaken in 28 patients, 19 F and 9 M, of mean age 56 years +/- 12. Previous antireflux procedures included 19 open and 12 laparoscopic antireflux operations. Symptoms were heartburn (90%), dysphagia (35%), and atypical symptoms (30%%). The mean interval from antireflux procedure to revision was 13 months +/- 4.2. The mean DeMeester score was 78+/-32 (normal 14.7). Eighteen patients (64%) had hiatal breakdown, 17 (60%) had wrap failure, 2 (7%) had slipped Nissen, 3 (11%) had paraesophageal hernias, and 1 (3%) had an excessively tight wrap. Twenty-five revisions were completed laparoscopically, while 3 patients required conversion to the open technique. Complications occurred in 9 of 17 (53%) patients failing previous open fundoplications and in 4 of 12 patients (33%) failing previous laparoscopic fundoplications and included 15 gastrotomies and 1 esophagotomy, all repaired laparoscopically, 3 postoperative gastric leaks, and 4 pneumothoraces requiring tube thoracostomy. No deaths occurred. Median length of stay was 5 days (range 2-90 days). At a mean follow-up of 20 months +/- 17, 2 patients (7%) have failed revision of their fundoplications, with the rest of the patients being essentially asymptomatic (93%). The results achieved with reoperative laparoscopic fundoplication are similar to those of primary laparoscopic fundoplications. Laparoscopic reoperations, particularly of primary open fundoplication, can be technically challenging and fraught with complications. Copyright 2001 Academic Press.

Revision rates and cumulative financial burden in patients treated with hemiarthroplasty compared to cannulated screws after femoral neck fractures.

This study compares re-operation rates and financial burden following the treatment of femoral neck fractures treated with hemiarthroplasty compared to non-displaced femoral neck fractures treated with cannulated screws. Data was retrospectively analyzed from a prospective database at a university hospital setting on patients undergoing hemiarthroplasty after femoral neck fractures and those with non-displaced femoral neck fractures treated with cannulated screws over a 7-year period. Re-operation rates were determined and financial data was analyzed. Charges refer to amounts billed by the hospital to insurance carriers, while costs refer to financial burden carried by the hospital during treatment. There were 491 femoral neck fractures (475 patients) that underwent hemiarthroplasty (HA) and 120 non-displaced fractures (119 patients) treated with cannulated screw (CannS) fixation. Both groups had similar age, sex, Charlson co-morbidity scores, pre-operative Parker mobility scores, and 12-month mortality. There were 29 (5.9 %) reoperations in the HA group and 16 (13.3 %) in the CannS group (P = 0.007). The majority of re-operations occurred within 12 months for both groups [21/29 (72 %) HA group; 15/16 (94 %) CannS group; P = 0.13]. Average hospital charges per patient for the index procedure were higher in the HA group ($17,880 ± 745) compared to the CannS group ($14,104 ± 5,047; P < 0.001). After accounting for additional procedures related to their initial surgical fixation, average hospital charges and costs remained higher in the HA group. Patients treated with hemiarthroplasty for femoral neck fractures have lower re-operation rates than patients treated with cannulated screws for non-displaced femoral neck fractures, with 80 % of re-operations occurring in the first 12 months. Hospital charges and costs to the hospital for treating patients undergoing hemiarthroplasty were higher than patients treated with cannulated screws for the index procedure alone, and after accounting for re-operations.

Resective surgery is a safe and effective treatment of drug-resistant epilepsy. If surgery has failed reoperation after careful re-evaluation may be a reasonable option. This study was to summarise the risks and benefits of reoperation in patients with epilepsy. This is a retrospective single centre study comprising clinical data, long-term seizure outcome, neuropsychological outcome and postoperative complications of patients, who had undergone a second resective epilepsy surgery from 1989 to 2009. A total of 66 patients with median follow-up of 10.3 years were included into the study. Fifty-one patients (77%) had surgery for temporal lobe epilepsy, the remaining 15 cases for extra-temporal lobe epilepsies. The most frequent histological findings were tumours (n=33, 50%), followed by dysplasia, gliosis (n=11, each) and hippocampus sclerosis (n=9). The main reasons for seizure recurrence were incomplete resection (59.1%) of the putative epileptogenic lesion. After reoperation 46 patients (69.7%) were completely seizure-free International League Against Epilepsy 1 (ILAE 1) at the last available follow-up. The neuropsychological evaluation demonstrated that repeated losses in the same cognitive domain, that is, successive changes from better to worse performance categories, were rare and that those losses after first surgery were followed by improvement rather than decline. However, reoperations lead to an increased rate of permanent neurological deficits (9%), overall surgical complications (9%) and visual field deficits (67%). Reoperation after failed resective epilepsy surgery led to approximately 70% long-time seizure freedom and reasonable neuropsychological outcome. There is an increased risk of permanent postoperative neurological deficits, which should be taken into consideration when counselling for reoperation. Published by the BMJ Publishing Group Limited.

Introduction This article is related to complications of rhinoplasty and its main causes of reoperations. Objectives The objective of this study is to perform a systematic review of literature on complications in rhinoplasty. Data Synthesis The authors conducted a survey of articles related to key terms in the literature by using three important databases within 11 years, between January 2002 and January 2013. We found 1,271 abstracts and selected 49 articles to this review. Conclusion The main results showed that the number of primary open rhinoplasty was 7902 (89%) and 765 closed (11%) and the percentage of reoperations in primary open complete rhinoplasties was 2.73% and closed complete was 1.56%. The statistical analysis revealed a value of p = 0.071. The standardization of terms can improve the quality of scientific publications about rhinoplasty. There is no difference between primary open or closed rhinoplasty techniques in relation to reoperations. PMID:28050215

To define the risk factors of complications which are followed by re-operations in patients with cardiac and pericardial wounds and to prevent these complications. Retrospective and prospective analysis of 1072 victims with cardiac and pericardial injuries for 35 years was performed. Overall mortality was 17.2%. 98 patients died during surgery. Postoperative bleeding was observed in 38 (3.9%) cases. In 28 cases re-operations were performed for bleeding-related complications. Indications for re-thoracotomy were one-time drainage from pleural cavity over 500 ml or bleeding rate over 100 ml per hour for 4 hours. Prevention of postoperative bleeding in case of cardiac and pericardial wounds was developed on basis of analysis of these observations. Risk factors of complications requiring re-operation are cardiomyopathy of different etiology, technical and tactical errors during primary intervention and hypocoagulation with massive blood loss. Prevention of these complications includes careful heart wound closure, comprehensive intraoperative control, correction of hemostatic system.

Implant survivorship is reported to be lower and complications, particularly bearing dislocation, are reported to be more frequent in Asian than in Western patients with medial knee osteoarthritis (OA) undergoing Oxford® Phase III unicompartmental knee arthroplasty (UKA). To date, however, these complications have not been compared between these groups of patients. The purpose of this study was to perform a meta-analysis comparing the standardized incidence rates of (1) all-cause reoperation; (2) reoperation related to bearing dislocation; and (3) reoperation related to progression of lateral compartment arthritis in Asian and Western patients with medial knee OA who underwent Oxford Phase III UKA. We searched MEDLINE® (January 1, 1976, to May 31, 2017), EMBASE® (January 1, 1985, to May 31, 2017), and the Cochrane Library (January 1, 1987, to May 31, 2017) for studies that reported complications of Oxford Phase III UKAs. Studies were included if they reported reoperation rates attributable to bearing dislocation and/or progression of lateral knee OA after surgery with this implant. Twenty-seven studies were included in this systematic review and 16 studies with followups > 5 years were included in the meta-analysis. These rates were converted to standardized incidence rate (that is, reoperations per 100 observed component years) based on mean followup and number of involved knees in each study. After applying prespecified inclusion and exclusion criteria, the studies were categorized into two groups, Asian and Western, based on hospital location. Twenty-five studies, containing 3152 Asian patients and 5455 Western patients, were evaluated. Study quality was assessed by the modified Coleman Methodology score (MCMS). Although all studies were Level IV, their mean MCMS score was 66.92 (SD, 8.7; 95% confidence interval [CI], 63.5-70.3), indicating fair quality. Because the heterogeneity of all subgroup meta-analyses was high, a random-effects model was used with estimations using the restricted maximum likelihood method. There was no difference in the proportion of Asian patients versus Western patients undergoing reoperation for any cause calculated as 100 component observed years (1.022 of 3152 Asian patients; 95% CI, 0.810-1.235 versus 1.300 of 5455 Western patients; 95% CI, 1.067-1.534; odds ratio, 0.7839; 95% CI, 0.5323-1.1545; p = 0.178). The mean reoperation rate attributable to bearing dislocation per 100 observed years was higher in Asian than in Western patients (0.525; 95% CI, 0.407-0.643 versus 0.141; 95% CI, 0.116-0.166; odds ratio, 3.7378; 95% CI, 1.694-8.248; p = 0.001) Conversely, the mean reoperation rate attributable to lateral knee OA per 100 observed years was lower in Asian than in Western patients (0.093; 95% CI, 0.070-0.115 versus 0.298; 95% CI, 0.217-0.379; odds ratio, 0.3114; 95% CI, 0.0986-0.9840; p < 0.001). Although total reoperation rates did not differ in the two populations, reoperation for bearing dislocation was more likely to occur in Asian than in Western patients, whereas reoperation for lateral knee OA progression was more likely to occur in Western than in Asian patients after Oxford Phase III UKA. Although possible explanations for these findings may be hypothesized, additional randomized, prospective comparative studies are needed. However, better survival outcomes after UKA may require consideration of ethnicity and lifestyle choices in addition to traditional surgical technique and perioperative care.

The optimal choice for pulmonary valve replacement (PVR) remains controversial. This study hypothesized that xenografts used for PVR would result in prolonged long-term survival and freedom from reoperation. Children and adults with congenital heart disease requiring PVR using a xenograft from 1980 to 1985 were reviewed. In all cases, the xenograft valve was either sewn or manufactured into a Dacron conduit, and the conduit was sewn to the pulmonary artery bifurcation. Clinical data were analyzed, and survival and freedom from reoperation were determined using Kaplan-Meier analysis. Twenty-four patients received a xenograft for PVR at 14.6 ± 5.6 years. Conduit size ranged from 21 to 27 mm. Most patients received a Carpentier-Edwards valved conduit (n = 17), followed by a Hancock valved conduit (n = 5) and an Ionescu-Shiley valve sewn into a Dacron graft (n = 2). No perioperative deaths occurred. Reoperation was required mainly for pulmonary stenosis (72.7%), followed by pulmonary insufficiency (18.2%), or both stenosis and insufficiency (9%). Freedom from reoperation was 90%, 56%, 43%, and 14% at 10, 20, 25, and 30 years, respectively. At most recent follow-up the was only death, which was related to severe biventricular failure 25 years after conduit implant. PVR using a xenograft valved conduit results in prolonged freedom from reoperation and excellent long-term survival. These data, which provide long-term follow-up information on xenograft valves after PVR. Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

Re-operative urethroplasty after failed hypospadias repair: how prior surgery impacts risk for additional complications.

2017-06-01

The primary aim of this report was to compare urethroplasty complications for primary distal and proximal repairs with those after 1, 2, 3, and 4 or more re-operations. Prospectively collected data on consecutive hypospadias repairs (tubularized incised plate (TIP), inlay, two-stage graft) from 2000 to 2015 were reviewed. Isolated fistula closures were excluded. Extracted information included patient age, meatal location, repair type, primary vs. re-operative surgery, number of prior operations, any testosterone use, glans width, and urethroplasty complications. Pre-operative testosterone stimulation was used during the study period until 2012. Initially, it was given for a subjectively small-appearing glans, but from 2008 to 2012 use was determined by glans width <14 mm. Patients initially managed elsewhere were queried for any testosterone treatment. The number of prior operations was determined by patient history and confirmed by review of records. Calibrations, dilations, cystoscopies, and/or isolated skin revisions were not considered as prior urethroplasty operations. Multiple logistic regression was performed for all patients, and for the subset of patients undergoing re-operation, using stepwise regression for the following potential risk factors: meatal location (distal vs. midshaft/proximal), number of prior surgeries (0, 1, 2, 3, ≥4), pre-operative testosterone use (yes/no), small glans (<14 vs. ≥14), surgery type (TIP, inlay and two-stage graft), and age (continuous in months), with P-values <0.05 considered statistically significant. In contrast to the 135/1085 (12%) complication rate in patients undergoing primary distal and proximal TIP repair, re-operative urethroplasty complications occurred in 61/191 (32%) TIP, 16/46 (35%) inlay, and 49/124 (40%) two-stage repairs, P<0.0001. Data regarding testosterone use was available for 1490 (96%) patients. A total of 139 received therapy, of which 65 (46%) had urethroplasty complications vs. 229 of 1351 (16%) without treatment, P = 0.0001. Logistic regression in 1536 patients demonstrated that each prior surgery increased the odds of subsequent urethroplasty complications 1.5-fold (OR 1.51, 95% CI 1.25-1.83), along with small glans <14 mm (OR 2.40, 95% CI 1.48-3.87), mid/proximal meatal location (OR 2.54, 95% CI 1.65-3.92), and use of pre-operative testosterone (OR 2.57, 95% CI 1.53-4.31); age and surgery type did not increase odds (AUC = 0.739). Urethroplasty complications doubled in people undergoing a second hypospadias urethroplasty compared with those undergoing primary repair. This risk increased to 40% with three or more re-operations. Logistic regression demonstrates that each surgery increases the odds for additional complications 1.5-fold. Mid/proximal meatal location, small glans <14 mm, and use of pre-operative testosterone also significantly increase odds for complications. These observations support the theory that previously operated tissues have less robust vascularity than assumed in a primary repair, and suggest additional adjunctive therapies are needed to improve wound healing in re-operations. The finding that even a single re-operative urethroplasty has twice the risk for additional complications vs. a primary repair emphasizes the need for hypospadias surgeons to 'get it right the first time'. The fact that 40% of the re-operative urethroplasties in this series followed distal repairs emphasizes that there is no 'minor' hypospadias. A single re-operative hypospadias urethroplasty has twice the risk for additional complications vs. the primary repair, which increases to 40% with three or more re-operations. These results support a theory that vascularity of penile tissues decreases with successive operations, and suggest the need for treatments to improve vascularity. The higher risk for complications during re-operative urethroplasties also emphasizes the need to get the initial repair correct. Copyright © 2016 Journal of Pediatric Urology Company.

Studies that evaluate the predictors and causes of unplanned re-operation in outpatient plastic surgery. This study retrospectively reviewed the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) and identified all plastic surgery outpatient cases performed in 2011. Multiple logistic regression analysis was utilised to identify independent risk factors and causes of unplanned reoperations. Of the 6749 outpatient plastic surgery cases identified, there were 125 (1.9%) unplanned re-operations (UR). Regression analysis demonstrated that body mass index (BMI, OR = 1.041, 95% CI = 1.019-1.065), preoperative open wound/wound infection (OR = 3.498, 95% CI = 1.593-7.678), American Society of Anesthesiologists (ASA) class 3 (OR = 2.235, 95% CI = 1.048-4.765), and total work relative value units (RVU, OR = 1.014, 95% CI = 1.005-1.024) were significantly predictive of UR. Additionally, the presence of any complication was significantly associated with UR (OR = 15.065, 95% CI = 5.705-39.781). In an era of outcomes-driven medicine, unplanned re-operation is a critical quality indicator for ambulatory plastic surgery facilities. The identified risk factors will aid in surgical planning and risk adjustment.

Laparoscopic Heller myotomy with antireflux procedure seems the procedure of choice in the treatment of patients with esophageal achalasia. Persistent or recurrent symptoms occur in 10% to 20% of patients. Few reports on reoperation after failed Heller myotomy have been published. No author has reported the realization of a total fundoplication in these patient groups. The aim of this study is to evaluate the efficacy of laparoscopic reoperation with the realization of a total fundoplication after failed Heller myotomy for esophageal achalasia. From 1992 to December 2007, 5 out of a series of 242 patients (2.1%), along with 2 patients operated elsewhere, underwent laparoscopic reintervention for failed Heller myotomy. Symptoms leading to reoperation included persistent dysphagia in 3 patients, recurrent dysphagia in another 3, and heartburn in 1 patient. Mean time from the first to the second operation was 49.7 months (range, 4-180 months). Always, the intervention was completed via a laparoscopic approach and a Nissen-Rossetti fundoplication was realized or left in place after a complete Heller myotomy. Mean operative time was 160 minutes (range, 60-245 minutes). Mean postoperative hospital stay was 3.1 +/- 1.5 days. No major morbidity or mortality occurred. At a mean follow-up of 16.1 months, reoperation must be considered successful in 5 out of 7 patients (71.4%). The dysphagia DeMeester score fell from 2.71 +/- 0.22 to 0.91 +/- 0.38 postoperatively. The regurgitation score changed from 2.45 +/- 0.34 to 0.68 +/- 0.23. Laparoscopic reoperation for failed Heller myotomy with the realization of a total fundoplication is safe and is associated with good long-term results if performed by an experienced surgeon in a center with a long tradition of esophageal surgery.

Mitigating Dam Impacts Using Environmental Flow Releases

One of the most ecologically disruptive impacts of dams is their alteration of natural river flow variability. Opportunities exist for modifying the operations of existing dams to recover many of the environmental and social benefits of healthy ecosystems that have been compromised by present modes of dam operation. The potential benefits of dam "re-operation" include recovery of fish, shellfish, and other wildlife populations valued both commercially and recreationally, including estuarine species; reactivation of the flood storage and water purification benefits that occur when floods are allowed to flow into floodplain forests and wetlands; regaining some semblance of the naturally dynamic balance between river erosion and sedimentation that shapes physical habitat complexity, and arresting problems associated with geomorphic imbalances; cultural and spiritual uses of rivers; and many other socially valued products and services. Assessing the potential benefits of dam re-operation begins by characterizing the dam's effects on the river flow regime, and formulating hypotheses about the ecological and social benefits that might be restored by releasing water from the dam in a manner that more closely resembles natural flow patterns. These hypotheses can be tested by implementing a re-operation plan, tracking the response of the ecosystem, and continually refining dam operations through adaptive management. This presentation will highlight a number of land and water management strategies useful in implementing a dam re-operation plan, with reference to a variety of management contexts ranging from individual dams to cascades of dams along a river to regional energy grids. Because many of the suggested strategies for dam re-operation are predicated on changes in the end-use of the water, such as reductions in urban or agricultural water use during droughts, a systemic perspective of entire water management systems will be required to attain the fullest possible benefits of dam re-operations.

Xenograft valved conduits have been used in several cardiac pathologies. In this study we have presented our midterm results of pediatric patients pathologies who were operated with xenograft conduits. Between January 1999 and January 2005, 134 patients underwent open heart surgery with xenograft conduits. The conduits were used to establish the continuity of the right ventricle to the pulmonary artery or aorta, the left ventricle to the pulmonary artery, or aorta due to various types of complex cardiac anomalies. Patients were evaluated by transthoracic echocardiography (ECHO) at 6-month follow-ups. Cardiac catheterization was performed when ECHO demonstrated significant conduit failure. Hospital mortality was observed in 28 patients (20.1%), and 13 patients died upon follow-up (9.7%). Mean follow-up was 24.6 +/- 4 months (range, 13 to 85 months). Among 93 survivors 20 patients (21.5%) were reoperated due to conduit failure. The main reasons for conduit failure were stenosis (n=13), valvular regurgitation (n=2), or both conditions in 5 cases. Mean pulmonary gradient before conduit re-replacement was 47.7 +/- 30.1 mmHg. The 1-, 3-, and 6-year actuarial survival rates were 95 +/- 2%, 91 +/- 3%, and 86 +/- 5%. The 1-, 3-, and 6-year actuarial freedom rates from reoperation were 95 +/- 1%, 90 +/- 3%, and 86 +/- 4%. An increased gradient between the pulmonary artery and the right ventricle and prolonged cardiopulmonary bypass times were observed to be significant risk factors for reoperation. There was no mortality among reoperated patients. Xenograft conduits should be closely followed for calcification and stenosis. Conduit stenosis is the major risk factor for reoperation. In these patients, reoperation for conduit replacement can be performed safely before deterioration of cardiac performance.

STUDY DESIGN. Retrospective audit of consecutive patients. OBJECTIve. To investigate the re-operation rate following elective primary lumbar microdiscectomy and to determine whether principal surgeon grade and/or disc space lavage is a factor in recurrence. SUMMARY OF BACKGROUND DATA. Recurrent herniation of disc material following lumbar microdiscecomy surgery is one of the commonest complications of the procedure. Any reduction in the number of revision microdiscectomies performed per year would have a significant impact on patients' lives and on the health service economy. We undertook this study to ascertain whether principal surgeon grade and/or disc space lavage has an impact in reducing the re-operation rate. METHODS. We undertook a retrospective audit of patients who underwent elective primary lumbar microdiscectomy, over a 3-year period (n = 971). RESULTS. The overall re-operation rate for primary elective microdiscectomy was 3.8%, consistent with the published literature. The relative risk of re-operation in patients primarily operated by registrar surgeons was 1.2 fold the risk in patients operated by consultants (95% CI: 0.62, 2.35) although not statistically significant (p = 0.568). The risk of re-operation in the 'non lavage' group was 2.15 times the risk in the 'lavage' group (95% CI: 0.63, 7.34), but it did not reach significance (p = 0.222). CONCLUSIONS. Principal surgeon grade and intervertebral disc lavage have not been found conclusively to be factors in the rate of recurrence. This information is useful to reassure patients that their outcome from such surgery is not dependent on the grade of surgeon performing the operation. There is a possible trend towards intervertebral disc lavage reducing the rate of recurrence.

Crohn's disease (CD) is a chronic inflammatory bowel disease known to carry a high risk of disabling and many times requiring surgical interventions. This article describes a decision-tree based approach that defines the CD patients' risk or undergoing disabling events, surgical interventions and reoperations, based on clinical and demographic variables. This multicentric study involved 1547 CD patients retrospectively enrolled and divided into two cohorts: a derivation one (80%) and a validation one (20%). Decision trees were built upon applying the CHAIRT algorithm for the selection of variables. Three-level decision trees were built for the risk of disabling and reoperation, whereas the risk of surgery was described in a two-level one. A receiver operating characteristic (ROC) analysis was performed, and the area under the curves (AUC) Was higher than 70% for all outcomes. The defined risk cut-off values show usefulness for the assessed outcomes: risk levels above 75% for disabling had an odds test positivity of 4.06 [3.50-4.71], whereas risk levels below 34% and 19% excluded surgery and reoperation with an odds test negativity of 0.15 [0.09-0.25] and 0.50 [0.24-1.01], respectively. Overall, patients with B2 or B3 phenotype had a higher proportion of disabling disease and surgery, while patients with later introduction of pharmacological therapeutic (1 months after initial surgery) had a higher proportion of reoperation. The decision-tree based approach used in this study, with demographic and clinical variables, has shown to be a valid and useful approach to depict such risks of disabling, surgery and reoperation.

The safety and efficacy of transanal drainage tube (TDT) placement to decrease the risk of postoperative anastomotic leakage after rectal cancer surgery has not been validated. The objective of this meta-analysis was to evaluate the usefulness of a TDT for the prevention of anastomotic leakage after an anterior resection for rectal cancer. The PubMed and Cochrane Library databases were searched for studies comparing TDT and non-TDT. The endpoint utilized in this study was defined as the rates of anastomotic leakage and re-operation. The relative effects of these variables were synthesized using Review Manager 5.1 software. Four trials including 909 participants (401 TDT cases and 508 non-TDT cases) met our inclusion criteria. The weighted mean anastomotic leakage rate was 4% [95% confidence interval (CI) 1-6%], and a significantly lower risk of anastomotic leakage was identified in the TDT group compared with the non-TDT group [odds ratio (OR) 0.30; 95% CI 0.16-0.55; p = 0.0001]. Furthermore, there were significant differences between the TDT and non-TDT groups in terms of the re-operation rate (OR 0.18; 95% CI 0.07-0.44; p = 0.0002). No significant covariates related to anastomotic leakage or re-operation were identified in meta-regression analysis. Both the anastomotic leakage and re-operation rates for all studies lay inside the 95% confidence interval boundaries. No visible publication bias was found by visual assessment of the funnel plot (Egger's test; anastomotic leakage: p = 0.056, re-operation: p = 0.681). Placement of a TDT is an effective and safe procedure that can decrease the rate of anastomotic leakage and re-operation after an anterior resection.

Tricuspid valve insufficiency (TI) following cardiovascular surgery causes right-side heart failure and hepatic failure, which affect patient prognosis. Moreover, the benefits of reoperation for severe tricuspid insufficiency remain unclear. We investigated the surgical outcomes of reoperation in TI. From the Japan Cardiovascular Surgery Database (JACVSD), we extracted cases who underwent surgery for TI following cardiac surgery between January 2006 and December 2011. We analysed the surgical outcomes, specifically comparing tricuspid valve replacement (TVR) and tricuspid valve plasty (TVP). Of the 167 722 surgical JACVSD registered cases, reoperative TI surgery occurred in 1771 cases, with 193 TVR cases and 1578 TVP cases. The age and sex distribution was 684 males and 1087 females, with an average age of 66.5 ± 10.8 years. The overall hospital mortality was 6.8% and was significantly higher in the TVR group than in the TVP group (14.5 vs 5.8%, respectively; P < 0.001). Incidences of dialysis, prolonged ventilation and heart block were also significantly higher in the TVR group than in the TVP group. Logistic regression analysis revealed that the risk factors of hospital mortality were older age, preoperative renal dysfunction, preoperative New York Heart Association Class 4, left ventricular dysfunction and TVR. Surgical outcomes following reoperative tricuspid surgery were unsatisfactory. Although TVR is a last resort for non-repairable tricuspid lesions, it carries a significant risk of surgical mortality. Improving the patient's preoperative status and opting for TVP over TVR is necessary to improve the results of reoperative tricuspid surgery. © The Author 2014.

A retrospective study of data abstracted from the Diagnosis Procedure Combination (DPC) database, a national representative database in Japan. The aim of this study was to examine seasonal variations in the risk of reoperation for surgical site infection (SSI) following spinal fusion surgery. Although higher rates of infection in the summer than in other seasons were thought to be caused by increasing inexperience of new staff, high temperature, and high humidity, no studies have examined seasonal variations in the risk of SSI following spinal fusion surgery in the country where medical staff rotation timing is not in summer season. In Japan, medical staff rotation starts in April. We retrospectively extracted the data of patients who were admitted between July 2010 and March 2013 from the DPC database. Patients were included if they were aged 20 years or older and underwent elective spinal fusion surgery. The primary outcome was reoperation for SSI during hospitalization. We performed multivariate analysis to clarify the risk factors of primary outcome with adjustment for patient background characteristics. We identified 47,252 eligible patients (23,659 male, 23,593 female). The mean age of the patients was 65.4 years (range, 20-101 yrs). Overall, reoperation for SSI occurred in 0.93% of the patients during hospitalization. The risk of reoperation for SSI was significantly higher in April (vs. February; odds ratio, 1.93; 95% confidence interval, 1.09-3.43, P = 0.03) as well as other known risk factors. In subgroup analysis with stratification for type of hospital, month of surgery was identified as an independent risk factor of reoperation for SSI among cases in an academic hospital, although there was no seasonal variation among those in a nonacademic hospital. This study showed that month of surgery is a risk factor of reoperation for SSI following elective spinal fusion surgery, nevertheless, in the country where medical staff rotation timing is not in summer season. 3.

High revision rate but good healing capacity of atypical femoral fractures. A comparison with common shaft fractures.

Healing of complete, atypical femoral fractures is thought to be impaired, but the evidence is weak and appears to be based on the delayed healing observed in patients with incomplete atypical fractures. Time until fracture healing is difficult to assess, therefore we compared the reoperation rates between women with complete atypical femoral fractures and common femoral shaft fractures. We searched the orthopaedic surgical registry in Östergötland County for patients with subtrochanteric and femoral shaft fractures (ICD-10 diagnosis codes S72.2, S72.3 and M84.3F) between January 1st 2007 and December 31st 2013. Out of 895 patients with surgically treated femoral shaft fractures, 511 were women 50 years of age or older. Among these we identified 24 women with atypical femoral shaft fractures, and 71 with common shaft fractures. Reoperations were performed in 6 and 5 patients, respectively, odds ratio 4.4 (95% CI 1.2 to 16.1). However, 5 reoperations in the atypical fracture group could not be ascribed to poor healing. In 3 patients the reoperation was due to a new fracture proximal to a standard intramedullary nail. In 2 patients the distal locking screws were removed due to callus formation that was deemed incomplete 5 months post-operatively. The one patient with poor healing showed faint callus formation at 5 months when the fracture was dynamised and callus remained sparse at 11 months. Among patients with common shaft fractures, 2 reoperations were performed to remove loose screws, 2 because of peri-implant fractures and 1 reoperation due to infection. Reoperation rates in patients with complete atypical femoral fractures are higher than in patients with common shaft fractures. The main reason for failure was peri-implant fragility fractures which might be prevented with the use of cephalomedullary nails at the index surgery. Fracture healing however, seems generally good. A watchful waiting approach is advocated in patients with fractures that appear to heal slowly. Copyright © 2015 Elsevier Ltd. All rights reserved.

High-performing health care organizations differentiate themselves by focusing on continuous process improvement initiatives aimed at enhancing patient outcomes. Reoperation for bleeding is an event associated with considerable morbidity risk. Hence, our primary objective was to develop and implement a formal operative checklist to reduce technical reasons for postoperative bleeding. From January 1, 2011, through June 30, 2012, 5812 cardiac surgical procedures were performed at Cleveland Clinic (Cleveland, OH). A multidisciplinary team developed a simple, easy-to-perform hemostasis checklist based on the most common sites of bleeding. An extensive educational in-service was performed before limited, then universal, checklist implementation. Geometric charts were used to track the number of cases between consecutive reoperations for bleeding. We compared these before (phase 0) and after the first limited implementation phase (phase 1) and the universal implementation phase (phase 2) of the checklist. The average number of cases between consecutive reoperations for bleeding increased from 32 in phase 0 to 53 in both phase 1 (P = .002) and phase 2 (P = .01). A substantial reduction in reoperation for bleeding cases followed implementation of a formalized hemostasis checklist. Our findings underscore the important influence of memory aids that focus attention on surgical techniques to improve patient outcomes in a complex, operative work environment.

Reimbursements for interbody fusions have declined recently because of their questionable cost-effectiveness. A Markov model was adopted to compare the cost-effectiveness of posterior lumbar interbody fusion (PLIF) or transforaminal lumbar interbody fusion (/TLIF) versus noninterbody fusion and posterolateral fusion (PLF) in patients with lumbar spondylolisthesis. Decision model analysis based on retrospective data from a single institutional series. One hundred thirty-seven patients underwent first-time instrumented lumbar fusions for degenerative or isthmic spondylolisthesis. Quality of life adjustments and expenditures were assigned to each short-term complication (durotomy, surgical site infection, and medical complication) and long-term outcome (bowel/bladder dysfunction and paraplegia, neurologic deficit, and chronic back pain). Patients were divided into a PLF cohort and a PLF plus PLIF/TLIF cohort. Anterior techniques and multilevel interbody fusions were excluded. Each short-term complication and long-term outcome was assigned a numerical quality-adjusted life-year (QALY), based on time trade-off values in the Beaver Dam Health Outcomes Study. The cost data for short-term complications were calculated from charges accrued by the institution's finance sector, and the cost data for long-term outcomes were estimated from the literature. The difference in cost of PLF plus PLIF/TLIF from the cost of PLF alone divided by the difference in QALY equals the cost-effectiveness ratio (CER). We do not report any study funding sources or any study-specific appraisal of potential conflict of interest-associated biases in this article. Of 137 first-time lumbar fusions for spondylolisthesis, 83 patients underwent PLF and 54 underwent PLIF/TLIF. The average time to reoperation was 3.5 years. The mean QALY over 3.5 years was 2.81 in the PLF cohort versus 2.66 in the PLIFo/TLIF cohort (p=.110). The mean 3.5-year costs of $54,827.05 after index interbody fusion were statistically higher than that of the $48,822.76 after PLF (p=.042). The CER of interbody fusion to PLF after the first operation was -$46,699.40 per QALY; however, of the 27 patients requiring reoperation, the incident (reoperation) rate ratio was 7.89 times higher after PLF (2.91, 26.67). The CER after the first reoperation was -$24,429.04 per QALY (relative to PLF). Two patients in the PLF cohort required a second reoperation, whereas none required a second reoperation in the PLIF/TLIF cohort. Taken collectively, the total CER for the interbody fusion is $9,883.97 per QALY. The reoperation rate was statistically higher for PLF, whereas the negative CER for the initial operation and first reoperation favors PLF. However, when second reoperations were included, the CER for the interbody fusion became $9,883.97 per QALY, suggesting moderate long-term cost savings and better functional outcomes with the interbody fusion.

OBJECTIVE Although reoperation and readmission have been used as quality metrics, there are limited data evaluating the rate of, reasons for, and predictors of reoperation and readmission after microsurgical clipping of unruptured aneurysms. METHODS Adult patients who underwent craniotomy for clipping of an unruptured aneurysm electively were extracted from the prospective National Surgical Quality Improvement Program registry (2011-2014). Multivariable logistic regression and recursive partitioning analysis evaluated the independent predictors of nonroutine hospital discharge, unplanned 30-day reoperation, and readmission. Predictors screened included patient age, sex, comorbidities, American Society of Anesthesiologists (ASA) classification, functional status, aneurysm location, preoperative laboratory values, operative time, and postoperative complications. RESULTS Among the 460 patients evaluated, 4.2% underwent any reoperation at a median of 7 days (interquartile range [IQR] 2-17 days) postoperatively, and 1.1% required a cranial reoperation. The most common reoperation was ventricular shunt placement (23.5%); other reoperations were tracheostomy, craniotomy for hematoma evacuation, and decompressive hemicraniectomy. Independent predictors of any unplanned reoperation were age greater than 51 years and longer operative time (p ≤ 0.04). Readmission occurred in 6.3% of patients at a median of 6 days (IQR 5-13 days) after discharge from the surgical hospitalization; 59.1% of patients were readmitted within 1 week and 86.4% within 2 weeks of discharge. The most common reason for readmission was seizure (26.7%); other causes of readmission included hydrocephalus, cerebrovascular accidents, and headache. Unplanned readmission was independently associated with age greater than 65 years, Class II or III obesity (body mass index > 35 kg/m 2 ), preoperative hyponatremia, and preoperative anemia (p ≤ 0.04). Readmission was not associated with operative time, complications during the surgical hospitalization, length of stay, or discharge disposition. Recursive partitioning analysis identified the same 4 variables, as well as ASA classification, as associated with unplanned readmission. The most potent predictors of nonroutine hospital discharge (16.7%) were postoperative neurological and cardiopulmonary complications; other predictors were age greater than 51 years, preoperative hyponatremia, African American and Asian race, and a complex vertebrobasilar circulation aneurysm. CONCLUSIONS In this national analysis, patient age greater than 65 years, Class II or III obesity, preoperative hyponatremia, and anemia were associated with adverse events, highlighting patients who may be at risk for complications after clipping of unruptured cerebral aneurysms. The preponderance of early readmissions highlights the importance of early surveillance and follow-up after discharge; the frequency of readmission for seizure emphasizes the need for additional data evaluating the utility and duration of postcraniotomy seizure prophylaxis. Moreover, readmission was primarily associated with preoperative characteristics rather than metrics of perioperative care, suggesting that readmission may be a suboptimal indicator of the quality of care received during the surgical hospitalization in this patient population.

Intermittent neural monitoring of the recurrent laryngeal nerve in surgery for recurrent goiter

Reoperative thyroid surgery is still challenging even for skilled surgeons, and is associated with a higher incidence of complications, such as hypoparathyroidism and recurrent laryngeal nerve (RLN) palsy. Displacement of the RLN, scar tissue from previous neck surgery and difficulty in maintaining good hemostasis are risk factors in reoperations. The prevalence of RLN injury in reoperative thyroid surgery ranges as high as 12.5% for transient injury and up to 3.8% for permanent injury. Bilateral paresis can also occur during reoperations, and is a dangerous complication influencing the quality of life, sometimes requiring tracheostomy. RLN identification is the gold standard during thyroidectomy, and the use of intraoperative neuromonitoring (IONM) can be a valuable adjunct to visual identification. This technique can be used to identify the RLN and the external branch of the superior laryngeal nerve (EBSLN), both of which are standardized procedures. The aim of this review was to evaluate the use of intermittent neural monitoring of the RLN in surgery for recurrent goiter, and to assess the prevalence of RLN injury while using IONM reported in the current literature.

Few studies discuss causes and outcomes of peritonitis in low-income settings. This study describes epidemiology of patients with peritonitis at a Rwandan referral hospital. Identification of risk factors associated with mortality and unplanned reoperation could improve management of peritonitis. Data were collected on demographics, clinical presentation, operative findings, and outcomes for all patients with peritonitis. Multivariate regression analysis identified factors associated with in-hospital mortality and unplanned reoperation. A total of 280 patients presented with peritonitis over a 6-month period. Causes of peritonitis were complications of intestinal obstruction (39%) and appendicitis (17%). Thirty-six (13%) patients required unplanned reoperation, and in-hospital mortality was 17%. Factors associated with increased odds of in-hospital mortality were unplanned reoperation (adjusted odds ratio 34.12), vasopressor use (adjusted odds ratio 24.91), abnormal white blood cell count (adjusted odds ratio 12.6), intensive care unit admission (adjusted odds ratio 9.06), and American Society of Anesthesiologist score ≥3 (adjusted odds ratio 7.80). Factors associated with increased odds of unplanned reoperation included typhoid perforation (adjusted odds ratio 5.92) and hypoxia on admission (adjusted odds ratio 3.82). Peritonitis in Rwanda presents with high morbidity and mortality. Minimizing delays in care is important, as many patients with intestinal obstruction present with features of peritonitis. A better understanding of patient care and management prior to arrival at the referral hospital is needed to identify areas for improvement at the health center and district hospital.

The optimal management of chronic subdural hematomas remains a challenge. Twist drill craniotomy or burr hole trephination are considered optimal initial treatments, but the reoperation rate for hematoma recurrence and other complications is still high. Therefore, evaluation of possible risk factors for initial treatment failure is crucial. In this context, we performed a study to define a possible subpopulation that may benefit from a more invasive initial treatment regime. We retrospectively reviewed the medical charts of 193 patients with 250 chronic subdural hematomas who had undergone burr hole trephination as first-line therapy in our institution between January 2005 and October 2012. To identify risk factors for reoperation, a multivariable logistic regression analysis was performed with reoperation as the dependent variable. Surgical complications, including acute rebleeding, infection and chronic hematoma recurrence, were analyzed separately using a logistic regression model. The mean age of the cohort was 71.4 years. The male/female ratio was 137:56. Reoperation was necessary in 56 cases (29%) for recurrent hematomas and surgical complications. Predictors for reoperation for surgical complications were midline shift (odds ratio [OR] (per mm) 1.16, 95% confidence interval [CI]: 1.05-1.29, p=0.006), arterial hypertension (OR 5.44, 95% CI: 1.45-20.41, p=0.012) and bilateral hematomas (OR 4.22, 95% CI: 1.22-14.58, p=0.023). There was a trend toward a higher risk of surgically-relevant hematoma recurrence in patients with prior treatment with vitamin K antagonists (OR 1.76, 95% CI: 0.75-4.13, p=0.191). Burr hole trephination is the therapy of choice in most chronic subdural hematomas, but the rate of recurrent hematomas is high. Every hematoma should be treated individually especially in relation to midline-shift and pre-existing conditions. Further prospective studies evaluating types of treatment and hematoma density are needed. Copyright © 2015 Elsevier B.V. All rights reserved.

Children undergoing Ross operation were expected to have longer autograft, but shorter homograft durability compared with adults. In order to define the outcome in the second decade after Ross operation in children, a nationwide review of 23 years of experience was undertaken. 305 children underwent Ross operation in 11 paediatric units between 1990 and 2012. Age at surgery was 9.4±5.7 years, indication aortic stenosis in 103 patients, regurgitation in 109 and mixed lesion in 93. 116 (38%) patients had prior procedures. Root replacement was performed in 201 patients, inclusion cylinder in 14, subcoronary grafting in 17 and Ross-Konno in 73. There were 10 (3.3%) hospital and 12 late deaths (median follow-up 8.7 years). Survival was 93±2% and 89±3% and freedom from any reoperation was 76±3% and 67±6% at 10 and 15 years. 34 children had autograft 37 reoperations (25 replacement, 12 repair): three required transplantation after reoperation. Freedom from autograft reoperation was 86±3% and 75±6% at 10 and 15 years. 32 children had right heart redo procedures, and only 25 (78%) conduit replacements (15-year freedom from replacement, 89±4%). Prior operation (p=0.031), subcoronary implant (p=0.025) and concomitant surgical procedure (p=0.004) were risk factors for left heart reoperation, while infant age (p=0.015) was for right heart. The majority (87%) of late survivors were in NYHA class I, 68% free from medication and six women had pregnancies. Despite low hospital risk and satisfactory late survival, paediatric Ross operation bears substantial valve-related morbidity in the first two decades. Contrary to expectation, autograft reoperation is more common than homograft. Published by the BMJ Publishing Group Limited.

The effects of chronic corticosteroid therapy on complications, readmission, and reoperation after posterior lumbar fusion (PLF) remain underinvestigated, and were examined to determine differences in outcomes. We analyzed patients undergoing PLF between 2006 and 2013 using the National Surgery Quality Improvement Program database (NSQIP). Patients taking steroids for a chronic condition were compared with those not taking steroids. Multivariable regression identified factors independently associated with complications, readmission, and reoperation. A risk score was calculated for predicting complications. A total of 8492 patients were identified, of whom 353 used steroids. The patients using steroids were older (mean age, 65.4 years vs. 61.0 years; P < 0.001), were more likely to be female (61.2% vs. 55.1%; P = 0.025), had a higher American Society of Anesthesiologists class (P < 0.001), were less likely to be functionally independent (90.3% vs. 96.5%; P < 0.001), and were more likely to have a history of hypertension (69.1% vs. 58.3%; P < 0.001), diabetes mellitus (21.8% vs. 17.4%; P = 0.033), cardiac disease (74.8% vs. 66.1%; P = 0.001), and/or severe chronic obstructive pulmonary disease (10.5% vs. 4.2%; P < 0.001). The rates of readmission (9.4% vs. 6.0%; P = 0.023), reoperation (6.5% vs. 3.6%; P = 0.004), overall complications (14.5% vs. 9.6%; P = 0.003), and infections (9.6% vs. 5.1%; P < 0.001) were higher in the steroid group. On multivariable regression, steroids were independently associated with overall complications (odds ratio [OR], 1.38; P = 0.044) and infectious complications (OR, 1.65; P < 0.001), but not with medical complications, readmission, or reoperation. Patients with higher risk scores had higher complication rates. The use of corticosteroid therapy is associated with a moderately increased risk of overall complications, but no association was found with readmission or reoperation. Copyright © 2017.

A number of studies on total hip arthroplasty have compared highly cross-linked polyethylene (HXLPE) with conventional polyethylene (CPE) liners beyond 10 years. However, the impact of HXLPE on the wear-related reoperation rate is unclear. The purpose of this study was to evaluate the clinical advantage of using a single manufacturer's HXLPE in terms of reducing the reoperation rate. The study was a follow-up retrospective cohort study over a mean of 12 years that examined patients aged 45-70 years with cementless total hip arthroplasty using a 26-mm-diameter cobalt-chromium head. Sixty-seven patients (79 hips; HXLPE group = 41 hips, CPE group = 38 hips) were evaluated for a minimum 10-year follow-up. Kaplan-Meier survival analysis was performed, with wear-related reoperations and radiographic osteolysis serving as the end points. The polyethylene wear rate was also assessed. The mean 12-year follow-up rates of survivorship that were evaluated using wear-related reoperations as the end point were 100% and 91.4% in the HXLPE and CPE groups, respectively (P = .007), and the mean 12-year follow-up rates of survivorship with osteolysis as the end point were 100% and 36.2%, respectively (P < .001). Compared with the CPE group, the HXLPE group presented a significantly reduced wear rate (HXLPE group, 0.035 mm/y; CPE group, 0.118 mm/y). A unique strength of this study is that we assessed a single manufacturer's HXLPE while keeping most other implant parameters uniform. This study reveals the clinical advantage of using a single manufacturer's HXLPE in terms of a reduced wear-related reoperation rate at a mean 12-year follow-up. Copyright © 2017 Elsevier Inc.

Records of 151 patients from the years 1964--1979 with anastomotic ulcers including relapses of ulcers after vagotomy reveal a total lethality of 3.3 per cent after reoperation. Re-gastrectomy with or without additional vagotomy shows a lethality of 5.7 per cent. If vagotomy alone is carried out there were no lethality and nearly no serious complications. Gastrectomy because of recurrent peptic ulcer after primary vagotomy has also no lethality. With regard to less serious postoperative complications including lethality after vagotomy instead of re-gastrectomy we should favour vagotomy for re-operation. Our further examinations will show whether this attitude is justified by long-term results after re-operation of the stomach in consequence of recurrent pepti ulcer.

The aim of this study was to evaluate the long-term results of the use of an autologous pericardial valved conduit in the outflow tract of the venous ventricle in congenital heart malformations. Fifty-one patients were followed up for a period of 12 to 120 months; 30 for more than 36 months and 13 for more than 72 months. All were evaluated clinically and by two-dimensional and Doppler echocardiography. Eight patients were recatheterized. Postoperative evaluation included serial measurement of pressure gradients and the conduit's diameter at the proximal, valvular, and distal levels. Reoperation because of stenosis was indicated when the gradient across the right ventricular outflow was greater than 50 mm Hg. The reoperation rate in relation with postoperative time, diameter of the autologous pericardial valved conduit at the time of implantation, and malformation was statistically analyzed. In 27 patients the conduit increased its diameter 1 to 7 mm. In 20 patients the diameter remained unchanged, whereas a reduction was noted in 4. Conduit survival free of reoperation for the whole group was 89.9% at 5 years. Conduit survival free of reoperation was 100% at 5 and 7 years for conduits larger than 16 mm at the time of implantation. It was 95% (standard deviation = 4.8%) at 5 years and 72.3% at 7 years for those 16 mm or less. For patients operated after January 1, 1986 (technical modification), conduit survival free of reoperation was 95.4% at 7 years postoperatively. These results compare favorably with those of other available conduits.

to evaluate functional results of reoperation performed according to the CIRCLE technology and using the VisuMax femtosecond laser and MEL-80 excimer laser in cases of regression of the refractive effect after SMILE surgery. We studied a group of post-SMILE patients. In those, who showed regression of the refractive effect at 1 year, reoperation was performed according to the CIRCLE technology and using the VisuMax femtosecond laser. The corneal flap was separated from the stromal bed and turned aside. Excimer laser ablation of the stromal bed was performed with the MEL 80 machine. The corneal flap was then placed back and rinsed from both sides. Uncorrected (UCVA) and corrected (BCVA) visual acuity as well as spherical equivalent (SE) were estimated before reoperation, on day 1, and at 1 month. After reoperation, BCVA and UCVA improved. Patient refraction became close to emmetropia. Specifically, UCVA was 0.23±0.18 at baseline (i.e. 1 year after SMILE) and 0.93±0.11 after the CIRCLE procedure (p<0.05). The absolute value of SE was 1.86±1.15 D and 0±0 D before and after CIRCLE, respectively (p<0.05). BCVA change was not statistically significant - from 0.95±0.1 to 0.93±0.11 (p>0.05). Reoperation performed according to the CIRCLE technology and using the VisuMax femtosecond laser and MEL-80 excimer laser provides an increase in visual acuity in case of post-SMILE regression of the refractive effect.

To assess the outcomes in children and adolescents with rheumatic fever of the implantation of mechanical as opposed to biological heart valves. We assessed 73 patients with rheumatic heart disease under the age of 18 years, who underwent replacement of heart valves between January, 1996, and December, 2005, at the National Institute of Cardiology in Rio de Janeiro, Brazil. Of the group, 71 patients survived, and were divided into a group of 52 receiving mechanical prostheses, and 19 with biological prostheses. We compared endpoints between the groups in terms of mortality, reoperation, haemorrhage, and stroke. Survival curves were estimated using the Kaplan-Meier method and were compared by the Mantel (log-rank) test. Overall mortality was 8.2%. In those receiving mechanical prostheses, 2 (3.8%) patients died, 5 (9.6%) underwent reoperation, 2 (3.8%) suffered severe haemorrhage, and 3 (5.8%) had strokes. In those receiving biological valves, 2 (10.5%) patients died, and 4 (21%) underwent reoperation. After 2, 4, and 8 years, overall survival was 96%, 93% and 86%, respectively, with a borderline difference between the groups (p = 0.06). The probabilities of remaining free from reoperation (p = 0.13), and from combined endpoints, showed no statistically significant difference between the groups (p = 0.28). Patients with mechanical prostheses had lower mortality and required fewer reoperations, but when all combined endpoints were considered, the groups did not differ. The biological prosthesis proved to be a good option for cardiac surgery in children and adolescents with difficulties or risks of anticoagulation.

Background Data demonstrating results of reoperation after initial tricuspid valve repair are scarce. We evaluated outcomes of tricuspid reoperations after tricuspid valve repair and compared the results of tricuspid re-repair with those of tricuspid valve replacement (TVR). Methods From 1994 to 2012, 53 patients (56±15 years, male:female =14:39) underwent tricuspid reoperations due to recurrent tricuspid regurgitation (TR) after initial repair. Twenty-two patients underwent tricuspid re-repair (TAP group) and 31 patients underwent TVR (TVR group). Results Early mortality occurred in 6 patients (11%). Early mortality and incidence of postoperative complications were similar between the 2 groups. There were 14 cases of late mortality including 9 cardiac deaths. Five- and 10-year free from cardiac death rates were 82% and 67%, respectively, without any intergroup difference. Recurrent TR (> moderate) developed in 6 TAP group patients and structural valve deterioration occurred in 1 TVR group patient (P=0.002). Isolated tricuspid valve surgery (P=0.044) and presence of atrial fibrillation during the follow-up (P=0.051) were associated with recurrent TR after re-repair. However, the overall tricuspid valve-related event rates were similar between the 2 groups with 5- and 10-year rates of 61% and 41%, respectively. Conclusions Tricuspid valve reoperation after initial repair resulted in high rates of operative mortality and complications. Long-term event-free rate was similar regardless of the type of surgery. However, great care might be needed when performing re-repair in patients with atrial fibrillation and those who had isolated tricuspid valve disease due to high recurrence of TR after re-repair.

The preparation for a reoperative cardiac surgical case was covered in Part I of this two part review [Tribble 2018]. Part II will cover primarily intraoperative strategies and techniques.  As noted in Part I, there has been surprisingly little written about the strategies and techniques of reoperative cardiac surgery. Thus, the goal of this two-part review is to collect and collate some of the lessons, abjurations, and tenets related to reoperative cardiac surgery that may be valuable to cardiac surgeons, especially those in training or early in their careers.Some time-honored admonitions that can apply to all complex operations, often enunciated by "old salts," bear repeating:•  Everything matters. Nothing is neutral.•  Some say that a "life or death" decision is made, on average, every 10 seconds during cardiac surgery. •  If something can go wrong, presume that it will.•  If it seems absolutely impossible for something to go wrong, it will anyway, at least some of the time.•  When something does go wrong, it generally does so all at once.•  If what you are doing is working, keep on doing it. If it ain't working, do something else.

For early-stage breast cancer, breast conservation surgery (BCS) is a conservative option for women and involves removing the tumor with a margin of surrounding breast tissue. If margins are not tumor free, patients undergo additional surgery to avoid local recurrence. To investigate the use of BCS in New York State and to determine rates of reoperation, procedure choice, and the effect of surgeon experience on the odds of a reoperation 90 days after BCS. A population-based sample of 89 448 women undergoing primary BCS for cancer were selected and examined from January 1, 2003, to December 31, 2013, in New York State mandatory reporting databases. All hospitals and ambulatory surgery centers in New York State were included. Data were analyzed from December 15, 2014, to November 1, 2015. Rate of reoperations within 90 days of the initial BCS procedure. During the study period, 89 448 women 20 years or older (mean [SD] age, 61.7 [13.7] years) underwent primary BCS. In 2013, 1416 women in New York aged 20 to 49 years underwent BCS compared with 3068 women aged 50 to 64 years and 3644 women 65 years or older. These numbers represent a significant decrease from 1960 women younger than 50 years in 2003 who underwent BCS (P < .001 for trend) but little change from the 2899 women aged 50 to 64 years and 3270 women 65 years or older who underwent BCS in 2003. Mean overall rate of 90-day reoperation was 30.9% (27 010 of 87 499 patients) and decreased over time from 39.5% (6630 of 16 805 patients) in 2003 to 2004 to 23.1% (5148 of 22 286 patients) in 2011 to 2013. Rates of reoperation were highest in women aged 20 to 49 years (37.7% [6990 of 18 524]) and lowest in women 65 years or older (26.3% [9656 of 36 691]) (P < .001 for trend). Over time, more patients underwent BCS as a subsequent procedure, from 4237 of 6630 patients (63.9%) in 2003 to 2004 to 4258 of 5148 (82.7%) in 2011 to 2013 (P < .001 for trend). Among the 19 466 women who underwent BCS as a second procedure, 2429 (12.5%) required a third intervention (2.7% of all women included). Significant surgeon-level variation was found in the data; 90-day rates of reoperations by surgeon ranged from 0% to 100%. Low-volume surgeons (<14 cases per year) had an unadjusted rate of 35.2% compared with 29.6% in middle-volume (14-33 cases per year) and 27.5% in high-volume (≥34 cases per year) surgeons. The difference persisted in adjusted analyses (odds ratio for low-volume surgeons, 1.49 [95% CI, 1.19-1.87]; for middle-volume surgeons, 1.20 [95% CI, 0.93-1.56]) compared with high-volume surgeons (used as the reference category). Use of BCS has decreased overall, most steeply in younger women. Nearly 1 in 4 women underwent a reoperation within 90 days of BCS across New York State from 2011 to 2013, compared with 2 in 5 from 2003 to 2004. Rates vary significantly by surgeon, and initial BCS performed by high-volume surgeons was associated with a 33% lower risk for a reoperation.

Pedicle screws are routinely used in contemporary spinal surgery. Screw misplacement may be asymptomatic but is also correlated with potential adverse events. Computer-assisted surgery (CAS) has been associated with improved screw placement accuracy rates. However, this technology has substantial acquisition and maintenance costs. Despite its increasing usage, no rigorous full economic evaluation comparing this technology to current standard of care has been reported. Medical costs are exploding in an unsustainable way. Health economic theory requires that medical equipment costs be compared with expected benefits. To answer this question for computer-assisted spinal surgery, we present an economic evaluation looking specifically at symptomatic misplaced screws leading to reoperation secondary to neurologic deficits or biomechanical concerns. The study design was an observational case-control study from prospectively collected data of consecutive patients treated with the aid of CAS (treatment group) compared with a matched historical cohort of patients treated with conventional fluoroscopy (control group). The patient sample consisted of consecutive patients treated surgically at a quaternary academic center. The primary effectiveness measure studied was the number of reoperations for misplaced screws within 1 year of the index surgery. Secondary outcome measures included were total adverse event rate and postoperative computed tomography usage for pedicle screw examination. A patient-level data cost-effectiveness analysis from the hospital perspective was conducted to determine the value of a navigation system coupled with intraoperative 3-D imaging (O-arm Imaging and the StealthStation S7 Navigation Systems, Medtronic, Louisville, CO, USA) in adult spinal surgery. The capital costs for both alternatives were reported as equivalent annual costs based on the annuitization of capital expenditures method using a 3% discount rate and a 7-year amortization period. Annual maintenance costs were also added. Finally, reoperation costs using a micro-costing approach were calculated for both groups. An incremental cost-effectiveness ratio was calculated and reported as cost per reoperation avoided. Based on reoperation costs in Canada and in the United States, a minimal caseload was calculated for the more expensive alternative to be cost saving. Sensitivity analyses were also conducted. A total of 5,132 pedicle screws were inserted in 502 patients during the study period: 2,682 screws in 253 patients in the treatment group and 2,450 screws in 249 patients in the control group. Overall accuracy rates were 95.2% for the treatment group and 86.9% for the control group. Within 1 year post treatment, two patients (0.8%) required a revision surgery in the treatment group compared with 15 patients (6%) in the control group. An incremental cost-effectiveness ratio of $15,961 per reoperation avoided was calculated for the CAS group. Based on a reoperation cost of $12,618, this new technology becomes cost saving for centers performing more than 254 instrumented spinal procedures per year. Computer-assisted spinal surgery has the potential to reduce reoperation rates and thus to have serious cost-effectiveness and policy implications. High acquisition and maintenance costs of this technology can be offset by equally high reoperation costs. Our cost-effectiveness analysis showed that for high-volume centers with a similar case complexity to the studied population, this technology is economically justified. Copyright © 2015 Elsevier Inc.

Surgical management of various forms of double-outlet right ventricle uses a variety of approaches depending on the underlying anatomic form. In this study, we sought to determine the risk factors of mortality and reoperation in those with double-outlet right ventricle undergoing biventricular repair, according to anatomic characteristics and initial surgical strategy. Between 1992 and 2013, 433 patients were included in the study. Double-outlet right ventricle was classified as double-outlet right ventricle with subaortic ventricular septal defect associated with subpulmonary obstruction in 33% of patients (n = 141), with subaortic ventricular septal defect without subpulmonary obstruction in 30% of patients (n = 130), with subpulmonary ventricular septal defect in 32% of patients (n = 139), and with noncommitted ventricular septal defect in 5% of patients (n = 23). Three types of repairs were performed: (1) intraventricular baffle repair, n = 149 (34%); (2) intraventricular baffle repair with right ventricular outflow tract reconstruction, n = 163 (38%); and (3) intraventricular baffle repair with arterial switch operation, n = 121 (28%). Thirty-day overall mortality was 7.4%. Early reoperation was needed in 6% of the cases. Early mortality was higher in the intraventricular baffle repair with arterial switch operation group (P = .01). Survival at 10 years was 86.2%, and freedom from reoperation at 10 years was 61.4%. At last follow-up (median, 5.7 years; 95% confidence interval, 4.5-6.6), mortality and reoperation rates were similar in the different surgical strategy groups. Late reoperation and late mortality were significantly higher in the double-outlet right ventricle with noncommitted ventricular septal defect group (P < .01). In multivariate analyses, risk factors for reoperation were concomitant surgical procedures (P = .03) and duration of cardiopulmonary bypass (P < .01). Risk factors for mortality were restrictive ventricular septal defect (P = .01), mitral cleft (P < .01), and associated coronary artery anomalies (P = .01). Those with the anatomic type of double-outlet right ventricle with noncommitted ventricular septal defect were at higher risk for reoperation and mortality.

OBJECT.: While transsphenoidal surgery is associated with low morbidity, the degree to which morbidity increases after reoperation remains unclear. The authors determined the morbidity associated with repeat versus initial transsphenoidal surgery after 1015 consecutive operations. The authors conducted a 5-year retrospective review of the first 916 patients undergoing transsphenoidal surgery at their institution after a pituitary center of expertise was established, and they analyzed morbidities. The authors analyzed 907 initial and 108 repeat transsphenoidal surgeries performed in 916 patients (9 initial surgeries performed outside the authors' center were excluded). The most common diagnoses were endocrine inactive (30%) or active (36%) adenomas, Rathke's cleft cysts (10%), and craniopharyngioma (3%). Morbidity of initial surgery versus reoperation included diabetes insipidus ([DI] 16% vs 26%; p = 0.03), postoperative hyponatremia (20% vs 16%; p = 0.3), new postoperative hypopituitarism (5% vs 8%; p = 0.3), CSF leak requiring repair (1% vs 4%; p = 0.04), meningitis (0.4% vs 3%; p = 0.02), and length of stay ([LOS] 2.8 vs 4.5 days; p = 0.006). Of intraoperative parameters and postoperative morbidities, 1) some (use of lumbar drain and new postoperative hypopituitarism) did not increase with second or subsequent reoperations (p = 0.3-0.9); 2) some (DI and meningitis) increased upon second surgery (p = 0.02-0.04) but did not continue to increase for subsequent reoperations (p = 0.3-0.9); 3) some (LOS) increased upon second surgery and increased again for subsequent reoperations (p < 0.001); and 4) some (postoperative hyponatremia and CSF leak requiring repair) did not increase upon second surgery (p = 0.3) but went on to increase upon subsequent reoperations (p = 0.001-0.02). Multivariate analysis revealed that operation number, but not sex, age, pathology, radiation therapy, or lesion size, increased the risk of CSF leak, meningitis, and increased LOS. Separate analysis of initial versus repeat transsphenoidal surgery on the 2 most common benign pituitary lesions, pituitary adenomas and Rathke's cleft cysts, revealed that the increased incidence of DI and CSF leak requiring repair seen when all pathologies were combined remained significant when analyzing only pituitary adenomas and Rathke's cleft cysts (DI, 13% vs 35% [p = 0.001]; and CSF leak, 0.3% vs 9% [p = 0.0009]). Repeat transsphenoidal surgery was associated with somewhat more frequent postoperative DI, meningitis, CSF leak requiring repair, and greater LOS than the low morbidity characterizing initial transsphenoidal surgery. These results provide a framework for neurosurgeons in discussing reoperation for pituitary disease with their patients.

Reinterventions after the Ross procedure are a concern for patients and treating physicians. The scope of the present report was to provide an update on the reinterventions observed in the large patient population of the German-Dutch Ross Registry. From 1988 to 2011, 2023 patients (age, 39.05 ± 16.5 years; male patients, 1502; adults, 1642) underwent a Ross procedure in 13 centers. The mean follow-up was 7.1 ± 4.6 years (range, 0-22 years; 13,168 patient-years). In the adult population, 120 autograft reinterventions in 113 patients (1.03%/patient-year) and 76 homograft reinterventions in 67 patients (0.65%/patient-year) and, in the pediatric population, 14 autograft reinterventions in 13 patients (0.91%/patient-year) and 42 homograft reinterventions in 31 patients (2.72%/patient-year) were observed. Of the autograft and homograft reinterventions, 17.9% and 21.2% were performed because of endocarditis, respectively. The subcoronary technique in the adult population resulted in significantly superior autograft durability (freedom from autograft reintervention: 97% at 10 years and 91% at 12 years; P < .001). The root replacement technique without root reinforcement (hazard ratio, 2.4; 95% confidence interval, 1.4-4.1) and the presence of pure aortic insufficiency preoperatively (hazard ratio, 2.3; 95% confidence interval, 1.5-3.5) were statistically significant predictors for a shorter time to reoperation. The center volume had a significant influence on the long-term results. The freedom from homograft reoperation for the adults and pediatric population was 97% and 87% at 5 years and 93% and 79% at 12 years, respectively (P < .001), with younger recipient and donor age being significant predictors of a shorter time to homograft reoperation. The autograft principle remains a valid option for young patients requiring aortic valve replacement. The risk of reoperation depends largely on the surgical technique used and the preoperative hemodynamics. Center experience and expertise also influence the long-term results. Adequate endocarditis prophylaxis might further reduce the need for reoperation. Copyright © 2012 The American Association for Thoracic Surgery. Published by Mosby, Inc. All rights reserved.

Double-Outlet Right Ventricle With Noncommitted Ventricular Septal Defect and 2 Adequate Ventricles: Is Anatomical Repair Advantageous?

PubMed

The management of double-outlet right ventricle associated with anatomically noncommitted ventricular septal defect constitutes a surgical challenge. The limits for, and the specific outcomes after anatomical vs univentricular repair still remain to be established. Between 1993 and 2011, 36 consecutive patients presenting with double-outlet right ventricle or noncommitted ventricular septal defect (21 inlet, 10 muscular, and 5 central perimembranous) and 2 adequately sized ventricles underwent surgical repair at 2 centers. Right ventricular outflow tract obstruction was present in 18 of 36 patients (50%). A total of 21 patients had undergone previous palliative procedures. Anatomical repair (group I) by means of intraventricular baffle construction was performed in 24 (associated right ventricular outflow tract reconstruction in 12 and arterial switch in 5) at a median age of 10.5 months. Ventricular septal defect was surgically enlarged in 12 (50%) patients. The remaining 12 patients underwent univentricular repair (group II). There were 4 hospital deaths (11%), all in group I (P = 0.30 vs group II). A total of 8 of 20 patients in group I survivors underwent 13 reoperations after a median delay of 24 months: subaortic stenosis was the main cause for reoperation in 6 of 8 patients. There was 1 late death in group I and 2 late deaths in group II. The median follow-up was 5.6 years (95% CI: 0.2-9.8). The 10- year actuarial survival rate and freedom from reoperation were 74.7 ± 5% and 58 ± 5% in group I and 71 ± 7% and 70 ± 7% in group II, respectively. At the last visit, all survivors were in New York Heart Association class I-II. Univariate analysis showed that atrioventricular septal defect and isolated mitral cleft were associated with death (P = 0.04) and need for reoperation (P = 0.038). In conclusion, anatomical repair, associated with substantial rates of mortality and need for reoperation, should be considered with caution. Associated atrioventricular septal defect and isolated mitral cleft were the only risk factors for mortality and reoperation. Copyright © 2016 Elsevier Inc. All rights reserved.

Mandible angle fractures can be repaired in a variety of ways, with no consensus on the outcomes of complications and reoperation rates. To analyze patient, injury, and surgical factors, including approach to the angle and plating technique, associated with postoperative complications, as well as the rate of reoperation with regard to mandible angle fractures. Retrospective cohort study analyzing the surgical outcomes of patients with mandible angle fractures between January 1, 2000, and December 31, 2015, who underwent open reduction and internal fixation. Patients were eligible if they were aged 18 years or older, had 3 or less mandible fractures with 1 involving the mandibular angle, and had adequate follow-up data. Patients with comminuted angle fractures, bilateral angle fractures, and multiple surgical approaches were excluded. A total of 135 patients were included in the study. All procedures were conducted at a single, large academic hospital located in an urban setting. Major complications and reoperation rates. Major complications included in this study were nonunion, malunion, severe malocclusion, severe infection, and exposed hardware. Of 135 patients 113 (83.7%) were men; median age was 29 years (range, 18-82 years). Eighty-seven patients (64.4%) underwent the transcervical approach and 48 patients (35.6%) received the transoral approach. Fifteen (17.2%) patients in the transcervical group and 9 (18.8%) patients in the transoral group experienced major complications (difference, 1%; 95% CI, -8% to 10%). Thirteen (14.9%) patients in the transcervical group and 8 (16.7%) patients in the transoral group underwent reoperations (difference, 2%; 95% CI, -13% to 17%). Active smoking had a significant effect on the rate of major complications (odds ratio, 4.04; 95% CI, 1.07 to 15.34; P = .04). During repair of noncomminuted mandibular angle fractures, both of the commonly used approaches-transcervical and transoral-can be used during treatment with equal rates of complication and risk of reoperation. For a patient undergoing surgery for mandibular angle fracture, smoking status is more likely to predict surgical outcomes rather than how the surgeon chooses to approach and fixate the fracture. 3.

Controversy persists regarding the use of protamine during carotid endarterectomy (CEA) based on prior conflicting reports documenting both reduced bleeding as well as increased stroke risk. The purpose of this study was to determine the effect of protamine reversal of heparin anticoagulation on the outcome of CEA in a contemporary multistate registry. We reviewed a prospective regional registry of 4587 CEAs in 4311 patients performed by 66 surgeons from 11 centers in Northern New England from 2003-2008. Protamine use varied by surgeon (38% routine use, 44% rare use, 18% selective use). Endpoints were postoperative bleeding requiring reoperation as well as potential thrombotic complications, including stroke, death, and myocardial infarction (MI). Predictors of endpoints were determined by multivariate logistic regression after associated variables were identified by univariate analysis. Of the 4587 CEAs performed, 46% utilized protamine, while 54% did not. Fourteen patients (0.64%) in the protamine-treated group required reoperation for bleeding compared with 42 patients (1.66%) in the untreated cohort (P = .001). Protamine use did not affect the rate of MI (1.1% vs 0.91%, P = .51), stroke (0.78% vs 1.15%, P = .2), or death (0.23% vs 0.32%, P = .57) between treated and untreated patients, respectively. By multivariate analysis, protamine (odds ratio [OR] 0.32, 95% confidence interval [CI], 0.17-0.63; P = .001) and patch angioplasty (OR 0.46, 95% CI, 0.26-0.81; P = .007) were independently associated with diminished reoperation for bleeding. A single center was associated with a significantly higher rate of reoperation for bleeding (OR 6.47, 95% CI, 3.02-13.9; P < .001). Independent of protamine use, consequences of reoperation for bleeding were significant, with a four-fold increase in MI, a seven-fold increase in stroke, and a 30-fold increase in death. Protamine reduced serious bleeding requiring reoperation during CEA without increasing the risk of MI, stroke, or death, in this large, contemporary registry. In light of significant complications referable to bleeding, liberal use of protamine during CEA appears warranted.

To determine the long-term outcomes of mitral valvuloplasty for myxomatous valve disease, rheumatic valve disease, and functional mitral regurgitation. A total of 1503 patients underwent mitral valvuloplasty by a single surgeon between February 1972 and April 2008 and were retrospectively reviewed for short- and long-term results. Overall mean age was 60.3 + or - 13.7 years, and 57% were male. The cause was rheumatic in 193 patients, myxomatous in 1042 patients, and ischemic and nonischemic functional mitral regurgitation in 236 patients. Ring annuloplasty was performed in 1306 patients (87%). Commissurotomy was the primary repair for rheumatic valves, posterior leaflet resection and reconstruction was the most common repair for myxomatous valves (527/1042 [51%]), and ring reduction annuloplasty was the primary operation for functional mitral regurgitation. The 30-day mortality was 19 of 1503 patients (1.3%) and significantly higher in the functional mitral regurgitation group (11/236 patients, 4.7% vs 0.5% in the rheumatic group and 0.6% in the myxomatous group, P < .01). The 10-, 20-, and 30-year survivals were similar for the rheumatic and myxomatous groups (77%, 56%, and 39% vs 79%, 62%, and 52%, respectively) but significantly less for the functional mitral regurgitation group (44%, 4%, and 0%, respectively, log-rank P < .0001). The 10- and 20-year freedom from reoperation rates were significantly better for the myxomatous group than for the rheumatic group (90% and 82% vs 66% and 34%, log-rank P < .0001), with a 30-year freedom from reoperation of only 10% for rheumatic repair. In the myxomatous group, freedom from reoperation was lower in patients with anterior leaflet pathology (P = .0008). Follow-up data to 36 years demonstrate that cause strongly determines survival and durability of mitral valvuloplasty; patients with rheumatic valve disease who survive more than 20 years require reoperation, whereas functional mitral regurgitation carries the highest short- and long-term mortality rates and lowest freedom from reoperation. Mitral valvuloplasty for myxomatous valves demonstrates the longest durability, with many patients free from reoperation at 30 years. Copyright 2010 The American Association for Thoracic Surgery.

Surgical treatment of aortic valve (AoV) disease in childhood involves complex decisions particularly in very small patients. There is no consensus regarding the optimum surgical option. The objective of this review was to analyze a contemporary experience of AoV surgery in a large children's hospital. A retrospective review of children (aged ≤ 18 years) undergoing AoV repair or replacement from June 1995 to December 2011 was carried out. A total of 285 AoV operations (97 repairs, 188 replacements) were performed on 241 patients. Hospital survival for repair was 98% and for replacements was 97%. At follow-up of repairs, there were 16 (17%) reoperations and 3 (3%) late deaths. Follow-up of AoV replacements demonstrated 31 (16%) reoperations (homograft 27, autograft 3, mechanical 1) and 8 (4%) late deaths (homograft 5, autograft 2, mechanical 1). Freedom from reintervention or death (FRD) was found to be lower in repairs for infants (P = .048) and truncal valves (P < .05). For AoV replacements, infants and patients who had concomitant CHD or homografts (P < .0001) had lower FRD. Cox regression analysis for AoV replacements identified infants and homograft root replacements at a higher risk for death/reoperation. AoV repairs and replacements were generally found to be associated with low death and reoperation rates at long-term follow-up. Infants had a lower freedom from reintervention or death after either an AoV repair or replacement, although truncal valve repairs and AoV replacement in patients with concomitant CHD were associated with lower valve survival. Among the valve options, homograft root replacement had a higher risk of death/reoperation and lowest freedom from reintervention or death.

Risk of reoperation and loss of a second native valve are major drawbacks of the Ross operation. Rather than discarding the failed autograft, it can be placed back into the native pulmonary position by "Ross reversal." We review our early and mid-term results with this operation. From 2006 to 2017, 39 patients underwent reoperation for autograft dysfunction. The autograft was successfully rescued in 35 patients: by Ross reversal in 30, David procedure in 4, and autograft repair in 1. Medical records were reviewed for patient characteristics (mean age was 46 ± 13 years, range 18-67 years, and 23 were male), previous operations, indications for reoperation, hospital outcomes, and echocardiographic findings for the 30 patients undergoing successful Ross reversal. Follow-up was 4.1 ± 3.5 years (range 7 months-11 years). Median interval between the original Ross procedure and Ross reversal was 12 years (range 5-19 years). Eight patients also had absolute indications for replacement of the pulmonary allograft. There was no operative mortality. One patient required reoperation for bleeding. Another had an abdominal aorta injury from use of an endoballoon clamp. There was no other major postoperative morbidity, and median postoperative hospital stay was 7.2 days (range 4-41 days). No patient required reoperation during follow-up. Twenty-four patients had acceptable pulmonary valve function, and 6 had clinically well-tolerated moderate or severe pulmonary regurgitation. Ross reversal can be performed with low morbidity and acceptable pulmonary valve function, reducing patient risk of losing 2 native valves when the autograft fails in the aortic position.

Long-term results with percutaneous interspinous process devices in the treatment of neurogenic intermittent claudication.

PubMed

Fransen, Patrick

2017-12-01

Neurogenic intermittent claudication (NIC) is the main symptom of degenerative lumbar spinal stenosis. Percutaneous interspinous process decompression devices (IPDs) have been designed as an alternative therapy to conservative treatment and to open decompressive surgery for patients suffering from NIC. Initial short-term results were encouraging. We present the long-term results of a group of patients that we followed to provide insight on long-term outcomes and effectiveness of this technique compared to other decompression methods. Fifteen patients operated for NIC by implantation of percutaneous IPDs have been prospectively monitored for reoperations or complications. Follow-up (FU) was interrupted if the patient was reoperated. Results were considered poor if the patient had to be reoperated at any stage of the FU or if the treatment failed to alleviate the pain after 6 months. Results were considered average if the patient still suffered some pain but did not require reoperation. The patients were followed up to 7 years after the initial surgery. The mean length of the FU was 3.53 years and all patients could be followed. At the end of the FU, the results were good in only 20.0% (3/15), average in 13.3% (2/15) and poor in 66.7% (10/15). Despite initial satisfactory results, long-term FU is disappointing, with 80% poor or average results. The long-term reoperation rate is high (66.6%), increases over time and is higher than after implantation of IPDs for decompression augmentation. Although this technique is simple and safe, its effectiveness seems short-lived. We recommend cautious use and informing patients about the risk of relatively early failure and recurrence.

We investigated our surgical strategy and clinical results in patients from active infective endocarditis (AIE) complicated by paravalvular involvement to determine the risk factors of early and late death and reoperation. From October 1979 to December 2014, 955 patients underwent operations for AIE; among them 207 had AIE with paravalvular extension. The patients were a mean age of 59.9 ± 15.4 years, and 162 (78%) were male. Of these patients, 137 (66%) had isolated aortic valve endocarditis, and 138 (67%) had native valve endocarditis. Follow-up was 99% complete. The operative mortality of the cohort was 16% (n = 34). Abnormal communication, mechanical valve implantation, and renal failure were independent predictors of 30-day death. Survival at 1, 5, 10, and 15 years was 90.3% ± 2.3%, 62.4% ± 3.7%, 49.3% ± 4.1%, and 37.9% ± 4.4%, respectively. Streptococcus endocarditis (all species), complex annular repair, and preoperative heart failure were independent predictors of long-term death. A reoperation was required in 29 patients (14%). Streptococcus pneumoniae endocarditis was the only independent predictor of early reoperation (within 30 days after the operation or during the same hospitalization). Freedom from reoperation at 1, 5, 10, and 15 years was 91.9% ± 2.2%, 89.6% ± 2.6%, 89.6% ± 2.6%, and 87.0% ± 3.5%, respectively. Independent predictors of late reoperation were urgent/emergency operation, prosthetic valve endocarditis, and complex annular repair. AIE complicated by paravalvular involvement remains a surgical challenge. Valve replacement (particularly using bioprosthesis) associated with ad hoc reconstruction seems to be a reliable option and showed very encouraging results in this context.

To compare recurrence frequency and location between different types of bowel resections in Crohn's disease patients. This was a retrospective study of consecutive patients undergoing bowel resection for Crohn's disease between 2006 and 2016. Type of primary operation was recorded and grouped as ileocolic resection, small bowel resection, segmental colon resection with colocolic anastomosis or colorectal anastomosis, colectomy with ileorectal anastomosis, or end stoma operation. Binary logistic regression was used to compare surgical recurrence frequency between groups. We also investigated how Crohn's disease location at reoperations was related to the primary bowel resection type. Altogether, 218 patients with a median follow-up of 4.7 years were included in our study. Reoperation was performed in 42 (19.3%) patients. The risk of reoperation using the ileocolic resection group as reference was the following: small bowel resection (odds ratio (OR) 2.95, 95% confidence interval (CI) 1.01-8.66; P = 0.049), segmental colon resection with colocolic or colorectal anastomosis (OR 6.20, 95% CI 2.04-18.87; P = 0.001), colectomy with ileorectal anastomosis (OR 26.57, 95% CI 2.59-273.01; P = 0.006), and end stoma operation (OR 4.62, 95% CI 1.90-11.26; P = 0.001). In case of surgical recurrence, the reoperation type and location correlated with the primary bowel resection type. Reoperation frequency in Crohn's disease is lower after ileocolic resection than after other types of bowel resections. Surgical recurrence in Crohn's disease tends to maintain the disease location of the primary operation. One third of Crohn's patients undergoing an end stoma operation will still need new bowel resections due to recurrence.

To evaluate the effects of using cryopreserved human amniotic membrane (AM) transplant during strabismus reoperations. A total of 30 patients with persistent strabismus were included in this prospective study. Patients were divided into two groups of 15 patients each. The AM group underwent strabismus reoperation with wrapping of the muscles with cryopreserved amniotic membrane. Controls underwent strabismus reoperation without an AM wrap. Final follow-up visit was scheduled between 3 and 12 months postoperatively. Surgical success was defined as 0 Δ -10 Δ of horizontal tropia and 0 Δ -4 Δ of vertical tropia, with no limitation of ductions exceeding -1. A cosmetically acceptable outcome was defined as a tropia of 0 Δ -15 Δ . Three patients were excluded in the AM group due to incomplete follow-up. A successful outcome was achieved in 7 patients in each group (58% and 47% in groups AM and C, resp.; P = 0.63). A cosmetically acceptable outcome was achieved in 10 patients in the AM group (83.3%) and 12 (80%) in the control group (P = 0.48). The mean ocular deviation angles improved to 8.7 Δ ± 12 Δ in the AM group and 12.3 Δ ± 17.4 Δ in the control group (P = 0.63). Ductions improved in 66.7% and 36.4% of the muscles with limited motility in groups AM and C, respectively (P = 0.019). Wrapping the extraocular muscles with cryopreserved AM during strabismus reoperations was of limited clinical benefit. We attributed this to the small segment of AM used and to the presence of other causes of failure rather than adhesions.

The authors' clinical experience is presented of non-structural valvular dysfunction of the prosthetic aortic valve caused by pannus ingrowth during the late postoperative period after previous heart valve surgery. Between January 1999 and April 2012, at the authors' institution, a total of 33 patients underwent reoperation for increased mean pressure gradient of the prosthetic aortic valve. All patients were shown to have pannus ingrowth. The mean interval from the previous operation was 16.7 +/- 4.3 years, and the most common etiology for the previous aortic valve replacement (AVR) was rheumatic valve disease. The mean effective orifice area index (EOAI) of the previous prosthetic valve was 0.97 +/- 0.11 cm2/m2, and the mean pressure gradient on the aortic prosthesis before reoperation was 39.1 +/- 10.7 mmHg. Two patients (6.1%) died in-hospital, and late death occurred in six patients (18.2%). At the first operation, 30 patients underwent mitral or tricuspid valve surgery as a concomitant procedure. Among these operations, mitral valve replacement (MVR) was combined in 24 of all 26 patients with rheumatic valve disease. Four patients underwent pannus removal only while the prosthetic aortic valve was left in place. The mean EOAI after reoperation was significantly increased to 1.16 +/- 0.16 cm2/m2 (p < 0.001), and the mean pressure gradient was decreased to 11.9 +/- 1.9 mmHg (p < 0.001). Non-structural valvular dysfunction caused by pannus ingrowth was shown in patients with a small EOAI of the prosthetic aortic valve and combined MVR for rheumatic disease. As reoperation for pannus overgrowth showed good clinical outcomes, an aggressive resection of pannus and repeated AVR should be considered in symptomatic patients to avoid the complications of other cardiac diseases.

Purpose Seprafilm® was initially used successfully as a membrane to reduce abdominal adhesions. Subsequently it was tried in a number of other areas to reduce postoperative scarring. Seprafilm® was employed in this study to see if it would reduce postoperative scarring after supraclavicular thoracic outlet decompression for neurogenic thoracic outlet syndrome (NTOS). Material and methods There were 249 operations for primary NTOS (185) and recurrent NTOS (64). Seprafilm® was applied to the nerve roots at the end of each procedure. Diagnosis was established by careful history and extensive physical exam consisting of several provocative maneuvers. Scalene muscle block confirmed the diagnosis. Results Success rates for primary operations, 1–2 years postoperation were 74% for scalenectomy without first rib resection and 70% for scalenectomy with first rib resection. For reoperations, success rate for scalenectomy and neurolysis after transaxillary rib resection was 78% whereas success rate for neurolysis after supraclavicular scalenectomy was 68%. Seprafilm® did not significantly improve overall results compared to our results 15 years ago, although in reoperations there was a trend toward improvement with Seprafilm®. Observations in 10 reoperations after use of Seprafilm® revealed that there were fewer adhesions between fat pad and nerve roots, making it much easier to find the nerve roots. Recurrence was because of scar formation around individual nerve roots. Conclusion Seprafilm® made reoperations easier by reducing scarring between scalene fat pad and brachial plexus. However, it did not prevent scar tissue forming around the individual nerve roots nor did it significantly lower the failure rate for primary operations. The trend supported the use of Seprafilm® in reoperations. PMID:18780049

The aim of this study was to compare the time to re-operation, following inadequate loco-regional surgery for breast cancer, between the public and private sectors of the Sunshine Coast region. A retrospective review was performed of the medical records of all female patients undergoing guide wire-localized, breast-conserving surgery at Nambour General Hospital and in the local private sector from January 2009 until April 2010. The dates of initial consultation, operation, post-operative consultation and any subsequent reoperation were recorded. One hundred and seventeen public sector patients and 113 private sector patients were identified during the study period. Thirty-seven public patients (32%) and 46 private patients (41%) required re-operation. This difference was not significant (χ(2) = 2.06, degrees of freedom (df) = 1, P = 0.15). The mean time and standard error from the initial consultation to the first operation and re-operation in the public sector was 26 (2.3) and 62 (3.8) days, and in the private sector was 12 (1.2) and 30 (4.4) days, respectively P < 0.001. On average, 70% of public patients and 96% of private patients completed the surgical component of their breast cancer management within the Queensland Health-recommended time frame of 30 days (χ(2) = 26, df = 1, P < 0.001). While experiencing similar rates of re-operative surgery in breast cancer management in the public and private sectors, the private sector deals with this issue in a more time efficient manner. An opportunity for intervention by quarantining theatre time is explored to improve the public sector time management. © 2015 Royal Australasian College of Surgeons.

This study examined 445 consecutive minimally invasive unicompartmental knee arthroplasties (UKAs) from one institution to determine whether revision and reoperation rates would decrease as the number of cases performed increased, indicating the presence of a learning curve with this procedure. At a mean of 3.25 years, 26 knees required revision yielding an overall revision rate of 5.8%; survivorship at 2 years with revision as an end point was 96% +/- 1.7%. Both revisions and reoperations decreased over time but not significantly. For the first half of UKA cases performed vs the second half, revision rates fell from 5.0% to 2.5%, and reoperation rates fell from 8.1% to 5.4%. These data demonstrate that despite modifications made to improve surgical technique across time, a substantial complication rate with this procedure persists. Copyright (c) 2010 Elsevier Inc.

Introduction The aim of the study was to analyse the risk factors of early and late mortality in patients undergoing the first reoperation for prosthetic valve dysfunction. Material and methods A retrospective observational study was performed in 194 consecutive patients (M = 75, F = 119; mean age 53.2 ±11 years) with a mechanical prosthetic valve (n = 103 cases; 53%) or bioprosthesis (91; 47%). Univariate and multivariate Cox statistical analysis was performed to determine risk factors of early and late mortality. Results The overall early mortality was 18.6%: 31.4% in patients with symptoms of NYHA functional class III-IV and 3.4% in pts in NYHA class I-II. Multivariate analysis identified symptoms of NYHA class III-IV and endocarditis as independent predictors of early mortality. The overall late mortality (> 30 days) was 8.2% (0.62% year/patient). Multivariate analysis identified age at the time of reoperation as a strong independent predictor of late mortality. Conclusions Reoperation in patients with prosthetic valves, performed urgently, especially in patients with symptoms of NYHA class III-IV or in the case of endocarditis, bears a high mortality rate. Risk of planned reoperation, mostly in patients with symptoms of NYHA class I-II, does not differ from the risk of the first operation. PMID:22291767

There is a lack of consensus about the surgical management of umbilical hernias. The aim of this study is to analyze the medium-term results of 934 umbilical hernia repairs. In this study, 934 patients with an umbilical hernia underwent surgery between 2004 and 2010, 599 (64.1%) of which were evaluated at least one year after the surgery. Complications, recurrence, and the reoperation rate were analyzed. Complications were observed in 5.7 per cent of the patients. With a mean follow-up time of 35.5 months, recurrence and reoperation rates were 3.8 per cent and 4.7 per cent, respectively. A higher percentage of female patients (60.9 % vs 29 %, P = 0.001) and a longer follow-up time (47.4 vs 35 months, P = 0.037) were observed in patients who developed a recurrence. No significant differences were observed between complications and the reoperation rate in patients who underwent Ventralex(®) preperitoneal mesh reinforcement and suture repair; however, a trend toward a higher recurrence rate was observed in patients with suture repair (6.5 % vs 3.2 %, P = 0.082). Suture repair had lower recurrence and reoperation rates in patients with umbilical hernias less than 1 cm. Suture repair is an appropriate procedure for small umbilical hernias; however, for larger umbilical hernias, mesh reinforcement should be considered.

Treatment of left-sided colorectal anastomotic leaks often requires fecal stream diversion for prevention of further septic complications. To manage anastomotic leak, it is unclear if diverting ileostomy provides similar outcomes to Hartmann resection with colostomy. We identified all patients who developed anastomotic leak following left-sided colorectal resections from 1/2012 through 12/2014 using the American College of Surgeons National Surgical Quality Improvement Program. Then, we examined the risk of mortality and abdominal reoperation in patients treated with diverting ileostomy as compared to Hartmann resection. There were 1745 patients who experienced an anastomotic leak in a cohort of 63,748 patients (3.7%). Two hundred thirty-five patients had a reoperation for anastomotic leak involving the formation of a diverting ileostomy (n = 77) or Hartmann resection (n = 158). There was no difference in mortality or abdominal reoperation in patients treated with diverting ileostomy (3.9, 7.8%) versus Hartmann resection (3.8, 6.3%) (p = 0.8). There was no difference in the outcomes of mortality or need for second abdominal reoperation in patients treated with diverting ileostomy as compared to Hartmann resection for left-sided colorectal anastomotic leak. Thus, select patients with left-sided colorectal anastomotic leaks may be safely managed with diverting ileostomy.

Due to the variations in anatomic location, the identification of parathyroid glands may be challenging. Although there have been advances in preoperative imaging modalities, there is still a need for an accurate intraoperative guidance. Indocyanine green (ICG) is a new agent that has been used for intraoperative fluorescence imaging in a number of general surgical procedures. Its utility for parathyroid localization in humans has not been reported in the literature. We report 3 patients who underwent reoperative neck surgery for primary hyperparathyroidism. Using a video-assisted technique with intraoperative ICG fluorescence imaging, the parathyroid glands were recognized and removed successfully in all cases. Surrounding soft tissue structures remained nonfluorescent, and could be distinguished from the parathyroid glands. This report suggests a potential utility of ICG imaging in intraoperative localization of parathyroid glands in reoperative neck surgery. Future work is necessary to assess its benefit for first-time parathyroid surgery. © The Author(s) 2015.

2016-01-01

We evaluated the short-term to midterm results of reoperation with bearing change to metal-on-polyethylene (MoP) after ceramic bearing fracture in ceramic-on-ceramic total hip arthroplasty. Nine third-generation ceramic bearing fractures (6 heads and 3 liners) were treated with bearing change to MoP. Mean age at reoperation was 52.7 years. Mean follow-up was 4.3 years. During follow-up, 2 of 3 liner-fractured hips and 1 of 6 head-fractured hips showed radiologic signs of metallosis and elevated serum chromium levels. Re-reoperation with bearing rechange to a ceramic head was performed for the hips with metallosis. One liner-fractured hip had periprosthetic joint infection. Dislocation occurred in 3 hips. From our experience, bearing change to MoP is not a recommended treatment option for ceramic bearing fracture in total hip arthroplasty. Copyright © 2016 Elsevier Inc. All rights reserved.

To describe the incidence and outcomes of reoperations for glaucoma in the Tube Versus Trabeculectomy (TVT) Study. Cohort study of patients in a multicenter randomized clinical trial. The TVT Study enrolled 212 patients with medically uncontrolled glaucoma who had previous cataract and/or glaucoma surgery. Randomization assigned 107 patients to surgery with a tube shunt (350 mm(2) Baerveldt glaucoma implant) and 105 patients to trabeculectomy with mitomycin C (0.4 mg/mL for 4 minutes). Data were analyzed from patients who failed their assigned treatment and had additional glaucoma surgery. Outcome measures included intraocular pressure (IOP), use of glaucoma medications, visual acuity, surgical complications, and failure (IOP >21 mm Hg or not reduced by 20%, IOP ≤5 mm Hg, additional glaucoma surgery, or loss of light perception vision). Additional glaucoma surgery was performed in 8 patients in the tube group and 18 patients in the trabeculectomy group in the TVT Study, and the 5-year cumulative reoperation rate was 9% in the tube group and 29% in the trabeculectomy group (P = .025). Follow-up (mean ± SD) after additional glaucoma surgery was 28.0 ± 16.0 months in the tube group and 30.5 ± 20.4 months in the trabeculectomy group (P = .76). At 2 years after a glaucoma reoperation, IOP (mean ± SD) was 15.0 ± 5.5 mm Hg in the tube group and 14.4 ± 6.6 mm Hg in the trabeculectomy group (P = .84). The number of glaucoma medications (mean ± SD) after 2 years of follow-up was 1.1 ± 1.3 in the tube group and 1.4 ± 1.4 in the trabeculectomy group (P = .71). The cumulative probability of failure at 1, 2, 3, and 4 years after additional glaucoma surgery was 0%, 43%, 43%, and 43%, respectively, in the tube group, and 0%, 9%, 20%, and 47% in the trabeculectomy group (P = .28). Reoperations to manage complications were required in 1 patient in the tube group and 5 patients in the trabeculectomy group (P = .63). The rate of reoperation for glaucoma was higher following trabeculectomy with mitomycin C than tube shunt surgery in the TVT Study. Similar surgical outcomes were observed after additional glaucoma surgery, irrespective of initial randomized treatment in the study. Copyright © 2014 Elsevier Inc. All rights reserved.

Outcome measures included intraocular pressure (IOP), use of glaucoma medications, visual acuity, surgical complications, and failure (IOP > 21 mm Hg or not reduced by 20%, IOP ≤ 5 mm Hg, additional glaucoma surgery, or loss of light perception vision). Results Additional glaucoma surgery was performed in 8 patients in the tube group and 18 patients in the trabeculectomy group in the TVT Study, and the 5-year cumulative reoperation rate was 9% in the tube group and 29% in the trabeculectomy group (p = .025). Follow-up (mean ± SD) after additional glaucoma surgery was 28.0 ± 16.0 months in tube group and 30.5 ± 20.4 months in the trabeculectomy group (p = .76). At 2 years after a glaucoma reoperation, IOP (mean ± SD) was 15.0 ± 5.5 mm Hg in the tube group and 14.4 ± 6.6 mm Hg in the trabeculectomy group (p = .84). The number of glaucoma medications (mean ± SD) after 2 years of follow-up was 1.1 ± 1.3 in the tube group and 1.4 ± 1.4 in the trabeculectomy group (p = .71).

Reoperations to manage complications were required in 1 (13%) patient in the tube group and 5 (28%) patients in the trabeculectomy group (p = .63). Conclusions The rate of reoperation for glaucoma was higher following trabeculectomy with mitomycin C than tube shunt surgery in the TVT Study. Similar surgical outcomes were observed after additional glaucoma surgery, irrespective of initial randomized treatment in the study. PMID:24531027

Radiation therapy rather than prior surgery reduces extent of resection during endonasal endoscopic reoperation for craniopharyngioma.

Radiation therapy is often advocated for residual or recurrent craniopharyngioma following surgical resection to prevent local recurrence. However, radiation therapy is not always effective and may render tumors more difficult to remove. If this is the case, patients may benefit more from reoperation if gross total resection can be achieved. Nevertheless, there is little data on the impact of radiation on reoperations for craniopharyngioma. In this study, we sought to analyze whether a history of previous radiation therapy (RT) affected extent of resection in patients with recurrent craniopharyngiomas subsequently treated with reoperation via endoscopic endonasal approach (EEA). The authors reviewed a prospectively acquired database of EEA reoperations of craniopharyngiomas over 13 years at Weill Cornell, NewYork-Presbyterian Hospital. All procedures were performed by the senior author. The operations were separated into two groups based on whether the patient had surgery alone (group A) or surgery and RT (group B) prior to recurrence. A total of 24 patients (16 male, 8 female) who underwent surgery for recurrent craniopharyngioma were identified. The average time to recurrence was 7.64 ± 4.34 months (range 3-16 months) for group A and 16.62 ± 12.1 months (range 6-45 months) for group B (p < 0.05). The average tumor size at recurrence was smaller in group A (1.85 ± 0.72 cm; range 0.5-3.2) than group B (2.59 ± 0.91 cm; range 1.5-4.6; p = 0.00017). Gross total resection (GTR) was achieved in 91% (10/11) of patients in group A and 54% (7/13) of patients in group B (p = 0.047). There was a near significant trend for higher average Karnofsky performance status (KPS) score at last follow-up for group A (83 ± 10.6) compared with group B (70 ± 16.3, p = 0.056). While RT for residual or recurrent craniopharyngioma may delay time to recurrence, ability to achieve GTR with additional surgery is reduced. In the case of recurrent craniopharyngioma, if GTR can be achieved, consideration should be given to endonasal reoperation prior to the decision to irradiate residual or recurrent tumor.

This study analyzes a single institution experience with minimally invasive mitral valve repair and evaluates long-term surgical outcomes of morbidity, mortality, and rates of reoperation. Late follow-up of mitral regurgitation and left ventricular function were also assessed. Between August 1996 and October 2007, minimally invasive mitral valve repair was performed in 713 patients (mean follow-up 5.7 years). Excluding 6 repairs with robotic assistance, an perspective analysis of the remaining 707 patients was carried forth. Mean age was 57 +/- 13 years. Mean preoperative ejection fraction was 60% +/- 10%. Surgical access was through a lower ministernotomy (74%), right parasternal incision (24%), right thoracotomy (1.4%), or upper ministernotomy (0.7%). Exposure of the mitral valve was through the left atrium in 58% of the cases and transeptal in 42%. A ring annuloplasty was incorporated into 680 (96%) of 707 repairs. The Kaplan-Meier and Student t test for paired samples were used for statistical analysis. There were 3 (0.4%) operative deaths. Perioperative morbidity included new-onset atrial fibrillation (20%), reoperation for bleeding (2%), stroke (1.9%), permanent pacemaker implantation (1.7%), deep sternal wound infection (0.7%), and aortic dissection (0.4%). Median hospital stay was 5 days. Only 31% of patients required blood transfusion during the hospital course. There were 49 (6.9%) late deaths and 34 (4.8%) failed repairs necessitating reoperation. At 11.2 years, survival was 83% (95% confidence intervals, 76.5-88.1); freedom from reoperation was 92% (95% confidence intervals, 86.2-94.9). Nine (1.3%) patients were lost to follow-up. A total of 2369 patient-years of echocardiography time were obtained in 544 patients (mean 4.36 years, range 0.47-11.09). Mean grade of mitral regurgitation decreased from 3.80 to 1.42 (P < .0001) Mean left ventricular ejection fraction decreased from 60.7% to 56.3% (P < .0001). Combined risk of death, reoperation, and recurrence of moderately severe to severe mitral regurgitation was 7.7% (43/555). Minimally invasive mitral valve repair is safe, with low perioperative morbidity, low rates of recurrent mitral regurgitation, and low rates of reoperation and death at late follow-up.

A well-functioning rotator cuff is necessary for successful anatomic total shoulder arthroplasty (TSA). This study evaluated patients who underwent concomitant TSA and rotator cuff repair (RCR) for functional outcomes, revision rates, and predictors of poor results. Retrospective chart review was conducted to identify patients who underwent TSA and RCR. Demographic data, rotator cuff tear and RCR characteristics, range of motion, and radiographs were recorded. Minimum 2-year functional outcomes were obtained. Predictors of reoperation and/or poor clinical results were determined. Forty-five patients met inclusion criteria (22 high-grade partial-thickness and 23 full-thickness tears). Fourteen (31%) patients were labeled as having a poor result; 8 (18%) patients required reoperation. There was a significant difference between the acromiohumeral interval preoperatively and immediately postoperatively (P=.013). However, at maximum radiographic follow-up, the acromiohumeral interval was not significantly different from preoperative values (P=.86). Patients with a preoperative acromiohumeral interval of less than 8 mm had an increased rate of cuff-related reoperation (P=.003). Although concomitant TSA and RCR is a reasonable consideration, 31% of patients had a poor clinical result. An acromiohumeral interval of less than 8 mm was a predictor of cuff-related reoperation and may be an indication to consider reverse arthroplasty in the setting of joint arthrosis with a rotator cuff tear.

Bar displacement is one of the most common and serious complications after the Nuss procedure. However, measurements of and factors affecting bar displacement have not been reported. The objectives of this study were to develop a decision model to guide surgeons considering repeat treatment and to estimate optimal cut-off values to determine whether reoperation to correct bar displacement is warranted. From July 2011 to August 2013, ninety bars were inserted in 61 patients who underwent Nuss procedures for pectus excavatum. Group A did not need surgical intervention and Group B required reoperation for bar displacement. Bar position was measured as the distance from the posterior superior end of the sternal body to the upper border of the metal bar on lateral chest radiographs. The bar displacement index (BDI) was calculated using D0 - Dx / D0 x 100 (D0: bar position the day after surgery; Dx: minimal or maximal distance of bar position on the following postoperative days). The optimal cut-off values of BDI warranting reoperation were assessed on the basis of ROC curve analysis. Of the 61 patients, 32 had single bars inserted whereas 29 had parallel bars inserted. There was a significant difference in age (14.0 ± 7.5 vs. 23.3 ± 12.0, p = 0.0062), preoperative Haller index (HI) (4.0 ± 1.1 vs. 5.0 ± 1.0, p = 0.033), and postoperative HI (2.7 ± 0.4 vs. 3.2 ± 0.5 p = 0.006) between the two groups. The optimal cut-off value of BDI was 8.7. We developed a BDI model for surgeons considering performing reoperation after Nuss procedure. The optimal cut-off value of BDI was 8.7. This model may help surgeons to decide objectively whether corrective surgery should be performed. The main factors affecting the relationship between bar displacement and reoperation were age and preoperative HI.

Perforated diverticulitis with purulent peritonitis has traditionally been treated with open colon resection and stoma formation with risk for reoperations, morbidity, and mortality. Laparoscopic lavage alone has been suggested as definitive treatment. To compare laparoscopic lavage with open colon resection and colostomy (Hartmann procedure) for perforated diverticulitis with purulent peritonitis. Randomized, controlled, multicenter, open-label trial. (ISRCTN registry number: ISRCTN82208287). 9 hospitals in Sweden and Denmark. Patients who have confirmed Hinchey grade III perforated diverticulitis with purulent peritonitis at diagnostic laparoscopy. Randomization between laparoscopic lavage and the Hartmann procedure. Primary outcome was the percentage of patients having 1 or more reoperations within 12 months. Key secondary outcomes were number of reoperations, hospital readmissions, total length of hospital stay during 12 months, and adverse events. A total of 43 and 40 patients were randomly assigned to laparoscopic lavage and the Hartmann procedure with a median (first, third quartiles) follow-up of 372 days (336, 394) and 378 days (226, 396), respectively. Fewer patients in the laparoscopic group (12 of 43; 27.9%) than in the Hartmann group (25 of 40; 62.5%) had at least 1 reoperation within 12 months (relative risk reduction, 59%; relative risk, 0.41 [95% CI, 0.23 to 0.72]; P = 0.004). Mortality and severe adverse events did not differ between groups. Total length of hospital stay (days) within 12 months was shorter for the laparoscopic group than the Hartmann group, with a reduction of 35% (relative risk, 0.65 [CI, 0.45 to 0.94]; P = 0.047). After 12 months, 3 patients in the laparoscopic group and 11 in the Hartmann group had a stoma. Not all patients presenting with suspected diverticulitis were enrolled. Laparoscopic lavage reduced the need for reoperations, had a similar safety profile to the Hartmann procedure, and may be an appropriate treatment of choice for acute perforated diverticulitis with purulent peritonitis.

Stentless prostheses have an interesting hemodynamic performance when compared to stented prostheses and are recommended in cases of small aortic annulus. From January 1996 to January 2004, 138 patients suffering from aortic disease, underwent aortic valve replacement. • Group A: 93 patients underwent stentless aortic valve implantation [stentless Biocor (Biocor Industria e Pesguisa Ltda, Belo Horizonte, Brazil) and stentless Sorin (Sorin Group, Saluggia, Italy)]. • Group B: 45 patients underwent stented aortic valve implantation (stented Biocor). Patients were assessed by clinical evaluation and echocardiography after a mean follow up of 124.5 ± 58.2 months. There was a significant difference in terms of time of extracorporeal circulation and aortic cross clamp. The actuarial survival at 4, 8, 12, and 15 years is 77%, 50%, 21%, and 18%, respectively. Freedom from reoperation at 4, 8, 12, and 14 years was 92%, 83%, 73%, and 63%, respectively. Freedom from all events, death, and reoperation at 4, 8, 12, and 14 years was 70%, 39%, 13%, and 8%, respectively. There is no statistical difference among the two groups in terms of actuarial survival, freedom from reoperation, and freedom from re-hospitalization for prosthesis-related causes. There was a significantly higher incidence of pacemaker implantation in Group A and the causes are not known. The rate of freedom from reoperation is high in both groups for the patients who remained alive. There was no statistical difference about prosthesis dysfunction between the two groups. The higher incidence of death in Group A cannot be explained by causes related to the prosthesis because there is no difference in terms of causes of death. Rates of reoperation did not differ between the two groups. The results obtained with stentless prostheses are encouraging even in long-term follow-up.

The purpose of this study was to compare the clinical efficacy of anterior cervical discectomy and fusion (ACDF) with Zero-profile device (Zero-p) and traditional cervical plate-and-cage implant in the treatment of symptomatic adjacent segment disease (ASD) and to determine the optimal reoperation procedure. This was a retrospective study of 58 patients with symptomatic ASD after an initial ACDF surgery and who had undergone a reoperation with ACDF with Zero-p (n = 27) and cervical plate-and-cage (n = 31) at our medical center between January 2010 and December 2015. The Japanese Orthopaedic Association score, Neck Disability Index score, Visual Analog Scale score, C2-C7 Cobb angle, and disc height index demonstrated significant improvements compared with the preoperative in both Zero-p and plate-and-cage groups (P < 0.05). However, there were no differences between the two groups (P > 0.05). The reoperation time for the Zero-p group (83.4 ± 18.9 min) was less than that for the plate-and-cage group (96.5 ± 20.1 min), with significant difference (P < 0.05). Five patients (8.6%) had cage subsidence, and 14 patients (24.1%) had dysphagia after the reoperation. There was no statistical significance in the difference between the 2 groups in cage subsidence (P > 0.05). However, the incidence of dysphagia in the plate-and-cage group (38.7%) was higher than in the Zero-p group (7.4%), with a significant difference (P < 0.05). ACDF with Zero-p obtaining the same surgical efficacy, compared with traditional cervical plate-and-cage, can significantly shorten the reoperation time and reduce the incidence of postoperative dysphagia. This option may be preferable for symptomatic patients with ASD qualifying for the anterior approach, in terms of biomechanics and surgical outcomes. Copyright © 2018 Elsevier Inc.

Abstract The aims of this study are (i) to report on the rates of subsequent surgery following hip arthroscopy and (ii) to identify prognostic variables associated with revision surgery, survival rates and complication rates. The Statewide Planning and Research Cooperative System database, a census of hospital admissions and ambulatory surgery in New York State, was used to identify cases of primary hip arthroscopy. Demographic information and rates of subsequent revision hip arthroscopy or arthroplasty were collected. The risks were modeled with use of age, sex, procedure and surgeon volume as risk factors. Survival analyses were also performed, and 30-day complication was recorded. We identified 8267 procedures in 7836 patients from 1998 to 2012. Revision surgery occurred in 1087 cases (13.2%) at a mean of 1.7 ± 1.6 (mean ± SD) years. Revision arthroscopy accounted for 311 cases (3.8%), and arthroplasty for 796 (9.7%) cases. Survival analysis showed a 2-year survival rate of 88.1%, 5-year of 80.7% and 10-year of 74.9%. Regression analysis revealed that age >50 years [hazard ratio (HR) 2.09; confidence interval (CI) 1.82–2.39, P < 0.01] and a diagnosis of osteoarthritis (HR 2.72; CI 2.21–3.34, P < 0.01) were associated with increased risk of re-operation. Labral repair was associated with a lower risk of re-operation (HR 0.71; CI 0.54–0.93, P = 0.01). Finally, higher surgeon volume (>164 cases/year) resulted in a lower risk of re-operation versus lower volume (<102 cases/year) (HR 0.42; CI 0.32–0.54, P < 0.01). The 30-day complication rate was 0.2%. Older age and pre-existing osteoarthritis increased the likelihood of re-operation following hip arthroscopy, whereas performing a labral repair and having the procedure performed by a higher-volume surgeon lowered the risk of re-operation.

Rheumatoid patients may develop a retrodental lesion (atlantoaxial rheumatoid pannus) that may cause cervical instability and/or neurological compromise. The objective is to characterize clinical and radiographic outcomes after posterior instrumented fusion for atlantoaxial rheumatoid pannus. We retrospectively reviewed all patients who underwent posterior fusions for an atlantoaxial rheumatoid pannus at a single institution. Both preoperative and postoperative imaging was available for all patients. Anterior or circumferential operations, non-atlantoaxial panni, or prior C1-C2 operations were excluded. Primary outcome measures included Nurick score, Ranawat score (neurologic status in patients with rheumatoid arthritis), pannus regression, and reoperation. Pannus volume was determined with axial and sagittal views on both preoperative and postoperative radiological images. Thirty patients surgically managed for an atlantoaxial rheumatoid pannus were followed for a mean of 24.43 months. Nine patients underwent posterior instrumented fusion alone, while 21 patients underwent posterior decompression and instrumented fusion. Following a posterior instrumented fusion in all 30 patients, the pannus statistically significantly regressed by 44.44%, from a mean volume of 1.26cm(3) to 0.70cm(3) (p<0.001), over 8.02 months. The Nurick score significantly improved from 2.40 to 0.60 (p<0.001), but the marginal improvement of 0.20 in the Ranawat score did not reach significance (p=0.312). Six patients (20%) required reoperations over a mean of 13.18 months. Reoperations were indicated for C1 instrumentation failure in four patients and pseudoarthrosis in two patients. Following posterior instrumented fusion, the pannus radiographically regressed by 44.44% over a mean of 8.02 months, and patients clinically improved per the Nurick score. The Ranawat score did not improve, and 20% of patients required reoperation over a mean of 13.18 months. The annualized reoperation rate was approximately 13.62%. Copyright © 2015 Elsevier B.V.

To compare radiographic failure and re-operation rates of anatomical coracoclavicular (CC) ligament reconstructional techniques with non-anatomical techniques after chronic high grade acromioclavicular (AC) joint injuries. We reviewed chronic AC joint reconstructions within a region-wide healthcare system to identify surgical technique, complications, radiographic failure and re-operations. Procedures fell into four categories: (1) modified Weaver-Dunn, (2) allograft fixed through coracoid and clavicular tunnels, (3) allograft loop coracoclavicular fixation, and (4) combined allograft loop and synthetic cortical button fixation. Among 167 patients (mean age 38.1 years, (standard deviation (sd) 14.7) treated at least a four week interval after injury, 154 had post-operative radiographs available for analysis. Radiographic failure occurred in 33/154 cases (21.4%), with the lowest rate in Technique 4 (2/42 4.8%, p = 0.001). Half the failures occurred by six weeks, and the Kaplan-Meier survivorship at 24 months was 94.4% (95% confidence interval (CI) 79.6 to 98.6) for Technique 4 and 69.9% (95% CI 59.4 to 78.3) for the other techniques when combined. In multivariable survival analysis, Technique 4 had better survival than other techniques (Hazard Ratio 0.162, 95% CI 0.039 to 0.068, p = 0.013). Among 155 patients with a minimum of six months post-operative insurance coverage, re-operation occurred in 9.7% (15 patients). However, in multivariable logistic regression, Technique 4 did not reach a statistically significant lower risk for re-operation (odds ratio 0.254, 95% CI 0.05 to 1.3, p = 0.11). In this retrospective series, anatomical CC ligament reconstruction using combined synthetic cortical button and allograft loop fixation had the lowest rate of radiographic failure. Anatomical coracoclavicular ligament reconstruction using combined synthetic cortical button and allograft loop fixation had the lowest rate of radiographic failure. ©2016 The British Editorial Society of Bone & Joint Surgery.

Object Symptomatic pediatric Chiari malformation Type I (CM-I) is most often treated with posterior fossa decompression (PFD), but controversy exists over whether the dura needs to be opened during PFD. While dural opening as a part of PFD has been suggested to result in a higher rate of resolution of CM symptoms, it has also been shown to lead to more frequent complications. In this paper, the authors present the largest reported series of outcomes after PFD without dural opening surgery, as well as identify risk factors for recurrence. Methods The authors performed a retrospective review of 156 consecutive pediatric patients in whom the senior authors performed PFD without dural opening from 2003 to 2013. Patient demographics, clinical symptoms and signs, radiographic findings, intraoperative ultrasound results, and neuromonitoring findings were reviewed. Univariate and multivariate regression analyses were performed to determine risk factors for recurrence of symptoms and the need for reoperation. Results Over 90% of patients had a good clinical outcome, with improvement or resolution of their symptoms at last follow-up (mean 32 months). There were no major complications. The mean length of hospital stay was 2.0 days. In a multivariate regression model, partial C-2 laminectomy was an independent risk factor associated with reoperation (p = 0.037). Motor weakness on presentation was also associated with reoperation but only with trend-level significance (p = 0.075). No patient with < 8 mm of tonsillar herniation required reoperation. Conclusions The vast majority (> 90%) of children with symptomatic CM-I will have improvement or resolution of symptoms after a PFD without dural opening. A non–dural opening approach avoids major complications. While no patient with tonsillar herniation < 8 mm required reoperation, children with tonsillar herniation at or below C-2 have a higher risk for failure when this approach is used. PMID:25932779

Renal cell carcinoma (RCC) with cavoatrial extension is a rare and complex problem. Complete resection is difficult but correlates with favorable patient outcomes. We present 2 cases of successful reoperative resections of recurrent RCC in patients with level III-IV cavoatrial involvement. We used a thoracoabdominal approach, peripheral cannulation, and hypothermic circulatory arrest. We advocate this novel approach as a successful means of avoiding a more difficult reoperation.

2017-10-01

Olecranon fractures are common and often require surgical treatment when displaced. Traditional methods of stabilization using tension band wire fixation and plate fixation achieve adequate union and function but are associated with a high rate of re-operation and wound problems because of prominent metalwork. The purpose of the present article is to describe an all suture technique for fixation of simple olecranon fractures that maintains inter-fragmentary compression, provides bony union and reduces the rate of re-operation caused by prominent metalwork.

There are few studies concerning specific total ankle arthroplasties. This study reports mid-term survival data for the AES prosthesis. Ninety-three AES ankle arthroplasties were performed by the senior authors. The mean follow-up was 3.5 years. The 5-year survivorship and also the number of simultaneous procedures, reoperations, additional procedures and revisions are analyzed. The 5-year survivorship with revision for any reason as end-point was 90%. Simultaneous procedures were performed in 25 patients, deltoid release and subtalar fusion being the most common. There were seven revisions, one due to loosening, and two due to infection, instability and fractures, respectively. Twenty-seven reoperations or additional procedures were performed in 23 patients with a procedure for malleolar impingement being the most common reoperation, and correction of hindfoot varus being the most common reason for an additional procedure. The AES total ankle replacement seems to be a reasonably safe procedure in experienced hands. Copyright 2009 European Foot and Ankle Society. Published by Elsevier Ltd. All rights reserved.

Intraoperative culture positive allograft bone and subsequent postoperative infections: a retrospective review.

Obtaining intraoperative cultures of allograft bone just before use in orthopedic procedures is standard practice in many centres; however, the association between positive cultures and subsequent surgical infections is unknown. Our study had 3 goals: to determine the prevalence of positive intraoperative allograft culture and subsequent infection; to determine if, in cases of subsequent infection, organisms isolated at reoperation were the same as those cultured from the allograft at the time of the index procedure; and to assess the costs associated with performing intraoperative allograft cultures. In this retrospective case series, we obtained data on patients receiving allograft bone between 2009 and 2012. Patients receiving allograft with positive cultures were reviewed to identify cases of significant infection. Organisms isolated at reoperation were compared with the allograft culture taken at the time of implantation, and we performed a cost assessment. Of the 996 allograft bone grafts used, 43 (4.3%) had positive intraoperative cultures and significant postoperative infections developed in 2, requiring reoperation. Antibiotics based on culture results were prescribed in 24% of cases. Organisms cultured at the time of reoperation differed from those isolated initially. The cost of performing 996 allograft cultures was $169 320. This series suggests that rates of positive intraoperative bone allograft culture are low, and subsequent infection is rare. In cases of postoperative infection, primary allograft culture and secondary tissue cultures isolated different organisms. Costs associated with performing cultures are high. Eliminating initial culture testing could save $42 500 per year in our health region.

The staged graft urethroplasty is a recommended technique for repairing complex hypospadias. This retrospective study aimed to investigate the outcomes of this technique in hypospadias patients undergoing reoperation and to analyze the underlying contributing factors including age, meatus location, and graft and suture type.We retrospectively analyzed 40 hypospadias patients undergoing reoperation who received a staged oral graft urethroplasty, including 15 buccal mucosal grafts and 25 lingual mucosal grafts. Median age at presentation was 18.5 years, and median follow-up was 17.5 months (range 8-30 months). The patients were classified according to their original meatus location.Twenty-five complications developed in 12 of 40 (30%) cases, including 6 fistulas (15%), 7 infections (17.5%), 9 cases of glans dehiscence (22.5%), and 3 cases of stenosis (7.5%). There was no significant difference in the overall complication rates between prepuberty and postpuberty groups. In addition, no significant difference in complications was found between the 2 graft techniques. The complications were significantly higher in the original perineal type compared with the original penoscrotal type (7/10 vs 5/30, P = .0031). Seven patients who originally had perineal hypospadias developed multiple complications.Based on this study, the staged graft urethroplasty is an effective technique in reoperative hypospadias repairs with reasonable complication risk. The hypospadias classification affects the surgical outcomes. Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc. All rights reserved.

Aortic surgery for progressive aortic valve disease or aortic aneurysm after previous coronary artery bypass grafting (CABG) is a challenging procedure. We report the outcome of aortic reoperation after previous CABG and evaluate our management of patent grafts and our methods for obtaining myocardial protection. From February 2001 to July 2003, 6 patients with progressive aortic valve disease and aneurysm of the thoracic aorta were operated on. The group comprised 3 men and 3 women with a mean age of 67.6 years. There were 4 patients with an aneurysm of the aortic arch, 1 with chronic ascending aortic dissection, and 1 with progressive aortic valve stenosis. The interval between previous CABG and aortic surgery was 74.0 +/- 44.2 months. All reoperations were performed via median resternotomy. Myocardial protection was obtained by hypothermic perfusion of patent in-situ arterial grafts following cold-blood cardioplegia administration via the aortic root under aortic cross clamping. The operative procedure was aortic arch replacement in 4 patients, ascending aortic replacement with double CABG in 1, and aortic valve replacement in 1. All patients survived the reoperation. Postoperative maximum creatine kinase-MB was 49.2 +/- 29.8 and no new Q-waves occurred in the electrocardiogram nor were any new wall motion abnormalities recognized on echocardiography. There were no late deaths during a follow-up of 30.7 months. Reoperative aortic procedures after CABG can be performed safely with myocardial protection via hypothermic perfusion of a patent in-situ arterial graft.

Adverse outcomes after surgery for pelvic organ prolapse (POP) with mesh are often attributed to the mesh material with little attention paid to the influence of surgeon factors. We used a national data set to determine whether surgeon case volume and specialty influenced vaginal prolapse surgery outcomes with mesh. Public Use File data on a 5% random national sample of female Medicare beneficiaries were obtained from the Centers for Medicare and Medicaid Services. Women with a diagnosis of POP who underwent surgery with mesh between 2007 and 2008 were identified by relevant International Classification of Diseases, 9th Revision, Clinical Modification and Current Procedural Terminology, 4th Edition procedure codes. Outcomes were compared by surgeon case volume and specialty. From 2007 to 2008, 1657 surgeries for POP were performed with mesh. Low-, intermediate-, and high-volume surgeons performed 881 (53%), 408 (25%), and 368 (22%) of the cases with mesh, respectively. The cumulative reoperation rates for low-, intermediate-, and high-volume providers were 6%, 2%, and 3%, respectively. The difference in reoperation rates between low and intermediate and low- and high-volume surgeons was statistically significant (P = 0.007 and 0.003, respectively). There was no significant difference in reoperation rates between gynecologists and urologists when vaginal mesh was implanted for POP surgery. Low-volume surgeons performed most of the vaginal prolapse repairs with mesh and had significantly higher reoperation rates. Surgeon experience must be a consideration when reporting mesh-related complications of POP surgery.

The replacement of a failed composite valve graft is technically more demanding and is associated with increased morbidity and mortality. We present our technique and outcomes for reoperations for composite graft failures. Between September 2011 and June 2017, 14 patients underwent a redo composite graft replacement. Twelve patients (85.7%) were male, and mean age was 58.4 years ± 12 standard deviation (SD). One patient had two previous root replacements. Indications for reoperation were endocarditis (8), aortic pseudoaneurysm (3), and aortic prosthesis thrombosis (3). Mean logistic EuroSCORE and EuroSCORE II were 30.8% and 14.7%, respectively. A mechanical composite graft was used in 12 patients and biological composite grafts were used in two patients. Hospital mortality was 14.3% (n = 2). One patient (7.1%) required reoperation for bleeding, One patient (7.1%) had mechanical ventilation >24 h, and four patients (28.6%) required implantation of a permanent pacemaker. Median intensive care unit and hospital stays were 3 days (interquartile range [IQR] 1-5) and 10 days (IQR 6.5-38.5). One patient experienced recurrent prosthetic valve endocarditis 14 months after operation. On follow-up, 11 of 12 survivors were in New York Heart Association class I or II. Survival at 3 years was 85.7% ± 9.4% SD. Composite valve graft replacement can be performed with acceptable morbidity and mortality with good mid-term survival. © 2018 Wiley Periodicals, Inc.

Volume-outcome relationships for open abdominal aortic aneurysm (AAA) repair have received less attention in publicly funded health systems. Furthermore, the roles of surgeon seniority (years of experience) and composite volume (encompassing all major arterial cases) on outcomes after open AAA repair are less well known. We sought to determine the effects of surgeon volume, surgeon years of experience, and composite volume on outcomes after elective open AAA repairs performed in Ontario, Canada. Using a population-based, prospectively collected health administrative database, all elective open AAA repairs occurring in the province of Ontario from 2005 to 2014 were identified. Surgeon annual volume was classified by quintiles, with the highest volume quintile acting as the reference category. Multivariable logistic regression modeling was used, adjusting for patient factors (age, sex, comorbidities, year of procedure, income) to investigate the relationship between surgeon annual volume and 30-day mortality, 30-day major complications, 30-day reoperations, 1-year mortality, and 1-year reoperations (related to index procedure). The potential effects of annual surgeon composite volume and surgeon years of experience on postoperative outcomes were also explored. A total of 7211 elective open AAA repairs performed by 101 surgeons were identified between 2005 and 2014. Most of the operations were performed by vascular surgeons (81.5%), followed by cardiac (12.1%) and general surgeons (6.1%). Median number of procedures in the lowest quintile group was 3 repairs/y, whereas the highest quintile group performed 54 repairs/y. Overall 30-day mortality was 3%. No difference in mortality was detected in comparing the lowest with the highest volume groups (1.89% vs 3.01%; adjusted odds ratio [OR], 0.60; 95% confidence interval [CI], 0.27-1.33). The lowest volume group exhibited a higher 30-day complication rate (28.0% vs 20.4%; OR, 1.54; 95% CI, 1.15-2.06) and 30-day reoperation rate (10.53% vs 6.73%; OR, 1.64; 95% CI, 1.13-2.38) compared with the highest volume group. No effect of surgeon volume on 1-year mortality or 1-year reoperation was observed. Similarly, composite volume and surgeon years of experience were not associated with postoperative outcomes. In a single-payer system with a relatively high number of open AAA repairs/surgeon per year, surgeon annual volume had no effect on postoperative mortality but was associated with lower postoperative complication and reoperation rates.

Despite the controversy, the aortic homograft is supposedly the best option in acute infective endocarditis (AIE), due to its resistance to reinfection. However, the technical complexity and the risk of structural deterioration over time have limited its utilization. The aim of this study was to evaluate the long-term results of aortic homograft for the treatment of infective endocarditis in our institution with particular attention to predictors of survival and homograft reoperation. The cohort includes 112 patients who underwent aortic valve replacement with an aortic homograft for AIE between January 1990 and December 2014. Fifteen patients (13.4%) died during the first 30 days after the operation. Two patients were lost to follow-up after discharge from the hospital; therefore, 95 patients were available for long-term analysis. The median duration of follow-up was 7.8 years (IQR 4.7-17.6). Five patients (5.3%) suffered a recurrence of infective endocarditis (1 relapse and 4 new episodes). Sixteen patients (16.8%) were reoperated for structural valve degeneration (SVD; n = 14, 87.5%) or for infection recurrence (n = 2, 12.5%). Freedom from homograft reoperation for infective endocarditis or structural homograft degeneration at 10 and 15 years postoperatively was 86.3 ± 5.5 and 47.3 ± 11.0%, respectively. For patients requiring homograft reoperation, the median interval to reintervention was 11.6 years (IQR 8.3-14.5). Long-term survival was 63.6% (95% CI 52.4-72.8%) and 53.8% (95% CI 40.6-65.3%) at 10 and 15 years, respectively. The use of aortic homograft in acute aortic valve endocarditis is associated with a remarkably low risk of relapsing infection and very acceptable long-term survival. The risk of reoperation due to SVD is significant after one decade especially in young patients. The aortic homograft seems to be ideally suited for reconstruction of the aortic valve and cardiac structures damaged by the infective process especially in early surgery. © The Author 2016.

OBJECTIVE The aim of this study was to investigate long-term seizure outcome, rate of reoperation, and postoperative neuropsychological performance following selective amygdalohippocampectomy (SelAH) or anterior temporal lobectomy (ATL) in pediatric patients with medically refractory temporal lobe epilepsy (TLE). METHODS The authors performed a retrospective review of cases of medically refractory pediatric TLE treated initially with either SelAH or ATL. Standardized pre- and postoperative evaluation included seizure charting, surface and long-term video-electroencephalography, 1.5-T MRI, and neuropsychological testing. RESULTS A total of 79 patients treated initially with SelAH (n = 18) or ATL (n = 61) were included in this study, with a mean follow-up of 5.3 ± 4 years (range 1-16 years). The patients' average age at initial surgery was 10.6 ± 5 years, with an average surgical delay of 5.7 ± 4 years between seizure onset and surgery. Seizure freedom (Engel I) following the initial operation was significantly more likely following ATL (47/61, 77%) than SelAH (8/18, 44%; p = 0.017, Fisher's exact test). There was no statistically significant difference in the proportion of patients with postoperative neuropsychological deficits following SelAH (8/18, 44%) or ATL (21/61, 34%). However, reoperation was significantly more likely following SelAH (8/18, 44%) than after ATL (7/61, 11%; p = 0.004) and was more likely to result in Engel I outcome for ATL after failed SelAH (7/8, 88%) than for posterior extension after failed ATL (1/7, 14%; p = 0.01). Reoperation was well tolerated without significant neuropsychological deterioration. Ultimately, including 15 reoperations, 58 of 79 (73%) patients were free from disabling seizures at the most recent follow-up. CONCLUSIONS SelAH among pediatric patients with medically refractory unilateral TLE yields significantly worse rates of seizure control compared with ATL. Reoperation is significantly more likely following SelAH, is not associated with incremental neuropsychological deterioration, and frequently results in freedom from disabling seizures. These results are significant in that they argue against using SelAH for pediatric TLE surgery.

Internal herniation, a serious complication after bariatric surgery, is challenging to diagnose. The aim of this study was to determine the accuracy of abdominal CT in diagnosing internal herniation. The study included consecutive patients who had undergone laparoscopic gastric bypass surgery between 1 January 2011 and 1 January 2015 at a bariatric centre of excellence. To select patients suspected of having internal herniation, reports of abdominal CT and reoperations up to 1 January 2017 were screened. CT was presumed negative for internal herniation if no follow-up CT or reoperation was performed within 90 days after the initial CT, or no internal herniation was found during reoperation. The accuracy of abdominal CT in diagnosing internal herniation was calculated using two-way contingency tables. A total of 1475 patients were included (84·7 per cent women, mean age 46·5 years, median initial BMI 41·8 kg/m 2 ). CT and/or reoperation was performed in 192 patients (13·0 per cent) in whom internal herniation was suspected. Internal herniation was proven laparoscopically in 37 of these patients. The incidence of internal herniation was 2·5 per cent. An analysis by complaint included a total of 265 episodes, for which 247 CT scans were undertaken. CT was not used to investigate 18 episodes, but internal herniation was encountered in one-third of these during reoperation. Combining the follow-up and intraoperative findings, the accuracy of CT for internal herniation had a sensitivity of 83·8 (95 per cent c.i. 67·3 to 93·2) per cent, a specificity of 87·1 (81·7 to 91·2) per cent, a positive predictive value of 53·4 (40·0 to 66·5) per cent and a negative predictive value of 96·8 (92·9 to 98·7) per cent. Abdominal CT is an important tool in diagnosing internal herniation, with a high specificity and a high negative predictive value. © 2018 BJS Society Ltd Published by John Wiley & Sons Ltd.

Many meta-analyses have been performed to study the efficacy of cervical disc arthroplasty (CDA) compared with anterior cervical discectomy and fusion (ACDF); however, there are few data referring to adjacent segment within these meta-analyses, or investigators are unable to arrive at the same conclusion in the few meta-analyses about adjacent segment. With the increased concerns surrounding adjacent segment degeneration (ASDeg) and adjacent segment disease (ASDis) after anterior cervical surgery, it is necessary to perform a comprehensive meta-analysis to analyze adjacent segment parameters. To perform a comprehensive meta-analysis to elaborate adjacent segment motion, degeneration, disease, and reoperation of CDA compared with ACDF. Meta-analysis of randomized controlled trials (RCTs). PubMed, Embase, and Cochrane Library were searched for RCTs comparing CDA and ACDF before May 2016. The analysis parameters included follow-up time, operative segments, adjacent segment motion, ASDeg, ASDis, and adjacent segment reoperation. The risk of bias scale was used to assess the papers. Subgroup analysis and sensitivity analysis were used to analyze the reason for high heterogeneity. Twenty-nine RCTs fulfilled the inclusion criteria. Compared with ACDF, the rate of adjacent segment reoperation in the CDA group was significantly lower (p<.01), and the advantage of that group in reducing adjacent segment reoperation increases with increasing follow-up time by subgroup analysis. There was no statistically significant difference in ASDeg between CDA and ACDF within the 24-month follow-up period; however, the rate of ASDeg in CDA was significantly lower than that of ACDF with the increase in follow-up time (p<.01). There was no statistically significant difference in ASDis between CDA and ACDF (p>.05). Cervical disc arthroplasty provided a lower adjacent segment range of motion (ROM) than did ACDF, but the difference was not statistically significant. Compared with ACDF, the advantages of CDA were lower ASDeg and adjacent segment reoperation. However, there was no statistically significant difference in ASDis and adjacent segment ROM.

Post-operative weight bearing after meniscal repair is a point of debate among physicians. This study sought to evaluate whether patients adhering to an immediate WBAT rehabilitation programme have a higher failure rate compared to those adhering to a more traditional, protected, NWB status following meniscal repair. The null hypothesis was that there would be no difference in failure between the two groups. A retrospective review of meniscal repair patients greater than 5 years from surgery was performed for patients receiving meniscal repair treatment. Patients were categorized by post-surgical weight-bearing status, either NWB or WBAT, and then analysed for failure of repair. Failure was defined as re-operation on the torn meniscus. The study controlled for variables including age at surgery, sex, height, weight, and BMI, classification of tear type, acuity of the tear, repair location (medial or lateral), repair location within the meniscus, repair technique, and concomitant procedures. Re-operations were performed in 61 of 157 patients [38.9%]. There was no difference between weight-bearing groups for failure of meniscus repair (n.s.). The tears were acute vertical tears located in the posterior horn and body. For the 61 patients with re-operation, the average time to re-operation was 2.2 years with 10 [16%] > 5 years from surgery, 17 [28%] 2-5 years from surgery, and 34 [56%] < 2 years from surgery. In isolated meniscal repair patients (n = 62), there was no difference between weight-bearing groups for rate of re-operation (n.s.). Weight bearing as tolerated after meniscal repair for peripheral, vertical tears does not result in a higher failure rate than traditional, non-weight bearing over a five-year follow-up period. The clinical relevance is that, based on these data, it may be appropriate to allow weight bearing as tolerated following meniscal repair of peripheral, vertical tears.

An actuarial "survivorship" analysis. The aim of this study was to define the incidence and cause of surgical revision 5 years after scoliosis surgery. Data on contemporary revision surgery rates after idiopathic scoliosis surgery beyond the 2 years postoperatively in the adolescent and young adult population are limited. Patients enrolled in a prospective, multicenter, idiopathic scoliosis surgical registry from 1995 to 2009 were reviewed. Any spine reoperation was defined as a "terminal event." An actuarial survivorship analysis that adjusts for patients lost to follow-up was performed to determine cumulative survival. Time intervals were defined as 0 to <3 months, 3 months to <1 year, 1 to <2 years, 2 to <5 years, and 5 to 10 years. Registry data and radiographs were reviewed and five categories for reoperation assigned: 1) implant failure and/or pseudarthrosis, 2) implant misplacement and/or prominence, 3) wound complication and/or infection, 4) residual deformity and/or progression, and 5) other. One thousand four hundred thirty-five patients from 12 sites were included. The majority were female (80%), with major thoracic curves (76% Lenke 1-4), and average age of 15 ± 2 years (10-22) at surgery. Most had posterior spinal instrumentation and fusion (81%). At this time, 75 (5.2%) patients required reoperation. Twenty-two occurred within 3 months postop, 10 more before 1 year, 12 more before 2 years, another 20 by 5 years, and 10 more after 5 years. This corresponded to an actuarial cumulative survival of 98.3% at 3 months, 97.5% at 1 year, 96.6% at 2 years, 93.9% at 5 years, and 89.8% at the final interval (5-10 yrs). Revisions for scoliosis continue to occur well after 2 years with a 5-year survivorship of 93.9%. Reasons for reoperation are not uniformly distributed over time, with implant-related issues and infection the leading cause for early revision, while late infection was the most common cause after 2 years. Long-term follow-up of these postoperative patients remains important. 3.

The management of open fractures requires wound irrigation and débridement to remove contaminants, but the effectiveness of various pressures and solutions for irrigation remains controversial. We investigated the effects of castile soap versus normal saline irrigation delivered by means of high, low, or very low irrigation pressure. In this study with a 2-by-3 factorial design, conducted at 41 clinical centers, we randomly assigned patients who had an open fracture of an extremity to undergo irrigation with one of three irrigation pressures (high pressure [>20 psi], low pressure [5 to 10 psi], or very low pressure [1 to 2 psi]) and one of two irrigation solutions (castile soap or normal saline). The primary end point was reoperation within 12 months after the index surgery for promotion of wound or bone healing or treatment of a wound infection. A total of 2551 patients underwent randomization, of whom 2447 were deemed eligible and included in the final analyses. Reoperation occurred in 109 of 826 patients (13.2%) in the high-pressure group, 103 of 809 (12.7%) in the low-pressure group, and 111 of 812 (13.7%) in the very-low-pressure group. Hazard ratios for the three pairwise comparisons were as follows: for low versus high pressure, 0.92 (95% confidence interval [CI], 0.70 to 1.20; P=0.53), for high versus very low pressure, 1.02 (95% CI, 0.78 to 1.33; P=0.89), and for low versus very low pressure, 0.93 (95% CI, 0.71 to 1.23; P=0.62). Reoperation occurred in 182 of 1229 patients (14.8%) in the soap group and in 141 of 1218 (11.6%) in the saline group (hazard ratio, 1.32, 95% CI, 1.06 to 1.66; P=0.01). The rates of reoperation were similar regardless of irrigation pressure, a finding that indicates that very low pressure is an acceptable, low-cost alternative for the irrigation of open fractures. The reoperation rate was higher in the soap group than in the saline group. (Funded by the Canadian Institutes of Health Research and others; FLOW ClinicalTrials.gov number, NCT00788398.).

Total ankle arthroplasty (TAA) and ankle arthrodesis (AA) are the main surgical treatment options for end-stage ankle arthritis. Although the superiority of each modality remains debated, there remains a lack of high-quality evidence-based studies, such as randomized controlled clinical trials, and meta-analyses of comparative studies. We performed a meta-analysis of comparative studies to determine whether there is a significant difference between these two procedures in terms of (i) clinical scores and patient satisfaction, (ii) re-operations, and (iii) complications. We conducted a comprehensive search in the MEDLINE, EMBASE, and Cochrane library databases. Only retrospective or prospective comparative studies were included in this meta-analysis. The literature search, data extraction, and quality assessment were conducted by two independent reviewers. The primary outcomes were clinical scores and patient satisfaction. We also investigated the prevalence of complications and the re-operation rate. Ten comparative studies were included (four prospective and six retrospective studies). There were no significant differences between the two procedures in the American Orthopaedic Foot and Ankle Society ankle-hindfoot score, Short Form-36 physical component summary and mental component summary scores, visual analogue scale for pain, and patient satisfaction rate. The risk of re-operation and major surgical complications were significantly increased in the TAA group. The meta-analysis revealed that TAA and AA could achieve similar clinical outcomes, whereas the incidence of re-operation and major surgical complication was significantly increased in TAA. Further studies of high methodological quality with long-term follow-up are required to confirm our conclusions.

There has been a trend toward limiting perioperative prophylactic antibiotics, based on research not conducted in plastic surgery patients. The authors' university hospital instituted antibiotic prescribing guidelines based on the Surgical Care Improvement Project. An increased rate of surgical-site infections was noted in breast reconstruction patients. The authors sought to determine whether the change in antibiotic prophylaxis regimen affected rates of surgical-site infections. A retrospective study compared patients undergoing breast reconstruction who received preoperative and postoperative prophylactic antibiotics with a group who received only a single dose of preoperative antibiotic. Type of reconstruction and known risk factors for implant infection were noted. Two hundred fifty patients were included: 116 in the pre-Surgical Care Improvement Project group and 134 in the Surgical Care Improvement Project group. The overall rate of surgical-site infections increased from 18.1 percent to 34.3 percent (p = 0.004). Infections requiring reoperation increased from 4.3 percent to 16.4 percent (p = 0.002). Multivariate logistic regression demonstrated that patients in the Surgical Care Improvement group were 4.74 times more likely to develop a surgical-site infection requiring reoperation (95 percent CI, 1.69 to 13.80). Obesity, history of radiation therapy, and reconstruction with tissue expanders were associated with increased rates of surgical-site infection requiring reoperation. Withholding postoperative prophylactic antibiotics in prosthetic breast reconstruction is associated with an increased risk of surgical-site infection, reoperation, and thus reconstructive failure. The optimal duration of postoperative prophylactic antibiotic use is the subject of future study.

Background Obtaining intraoperative cultures of allograft bone just before use in orthopedic procedures is standard practice in many centres; however, the association between positive cultures and subsequent surgical infections is unknown. Our study had 3 goals: to determine the prevalence of positive intraoperative allograft culture and subsequent infection; to determine if, in cases of subsequent infection, organisms isolated at reoperation were the same as those cultured from the allograft at the time of the index procedure; and to assess the costs associated with performing intraoperative allograft cultures. Methods In this retrospective case series, we obtained data on patients receiving allograft bone between 2009 and 2012. Patients receiving allograft with positive cultures were reviewed to identify cases of significant infection. Organisms isolated at reoperation were compared with the allograft culture taken at the time of implantation, and we performed a cost assessment. Results Of the 996 allograft bone grafts used, 43 (4.3%) had positive intraoperative cultures and significant postoperative infections developed in 2, requiring reoperation. Antibiotics based on culture results were prescribed in 24% of cases. Organisms cultured at the time of reoperation differed from those isolated initially. The cost of performing 996 allograft cultures was $169 320. Conclusion This series suggests that rates of positive intraoperative bone allograft culture are low, and subsequent infection is rare. In cases of postoperative infection, primary allograft culture and secondary tissue cultures isolated different organisms. Costs associated with performing cultures are high. Eliminating initial culture testing could save $42 500 per year in our health region. PMID:28234217

Reoperations of the mitral valve have a higher rate of complications when compared with the first surgery. With the field of video-assisted techniques for the first surgery of mitral valve became routine, reoperation cases began to arouse interest for this less invasive procedures. To assess the results and the technical difficulties in 10 patients undergoing minimally invasive redo mitral valve surgery. Cardiopulmonary bypass was installed through a cannula placed in the femoral vessels and right internal jugular vein, conducted in 28 degrees of temperature in ventricular fibrillation. A right lateral thoracotomy with 5 to 6 cm in the third or fourth intercostal space was done, pericardium was displaced only at the point of atriotomy. The aorta was not clamped. Ten patients with mean age of 56.9 ± 10.5 years, four were in atrial fibrilation rhythm and six in sinusal. Average time between first operation and reoperations was 11 ± 3.43 years. The mean EuroSCORE group was 8.3 ± 1.82. The mean ventricular fibrillation and cardiopulmonary bypass was respectively 70.9 ± 17.66 min and 109.4 ± 25.37 min. The average length of stay was 7.6 ± 1.5 days. There were no deaths in this series. Mitral valve reoperation can be performed through less invasive techniques with good immediate results, low morbidity and mortality. However, this type of surgery requires a longer duration of cardiopulmonary bypass, especially in cases where the patient already has prosthesis. The presence of a minimal aortic insufficiency also makes this procedure technically more challenging.

Distraction arthroplasty compared to other cartilage preservation procedures in patients with post-traumatic arthritis: a systematic review.

Rivera, Jessica C; Beachler, Jason A

2018-01-23

Post-traumatic arthritis (PTA) is characterized by the deterioration of articular cartilage temporally associated with an articular injury. With a paucity of literature comparing joint preservation techniques, we performed a systematic review of the literature intending to describe and summarize the results of ankle distraction arthroplasty as it compares with studies on tibio-talar microfracture, allograft, and autograft for ankle joint preservation in the post-traumatic population under 50 years of age. Research databases were searched and abstracts screened for relevance on our topic of interest. Abstracts meeting screening criteria with high interobserver reliability underwent full-manuscript review and coding for pertinent citation, study level, treatment, and outcome variables. Outcome variables for patient-reported pain scales, validated outcome measurement tools, radiographic progression, reoperation/re-treatment rates, and complication rates were recorded. Out of 105 unique citations, 10 publications were included. The distraction arthroplasty studies had 36 out of 181 patients requiring reoperation for complications (19.9%), while other joint-preserving procedures studies had 40 out of 177 patients requiring reoperations for complications (22.6%). Clinical outcome scores at mean follow-up time ranging from 2 to 10 years between studies were similar. Reported results for a variety of cartilage preservation procedures, including distraction arthroplasty, are satisfactory and reoperation rates for complication are similar. Limitations in available data and underlying study quality affect synthesis of the results therein. While distraction arthroplasty is an option for cartilage preservation in patients with PTA of the ankle, the technique is highly specialized which may affect the external validity. III.

Body contouring surgery is in high demand following the increase in bariatric surgery. But these types of procedures are associated with high complication rates that cause long hospital stays and have a negative effect on patient satisfaction. The purpose of this study is to identify predictors of complications in order to optimize outcomes in these patients and find a relationship between complication rate and satisfaction. Out of a group of 175 post-bariatric patients, 72 patients underwent body contouring surgery following massive weight loss from 2003-2008. They were reviewed retrospectively for demographic data, pre- and postoperative weight status, co-morbidities and complications and reoperation rate. Patient satisfaction was evaluated. a) The overall complication rate was 45.8%. The most frequent were seromas (23.6%); infection (13.9%), bleeding (11.1%), hematoma (6.9%) (needing transfusions [6.9%]), skin necrosis (6.9%) and umbilical necrosis (4.2%). A total of 8 patients required reoperation (11.1%). b) Satisfaction rating: 1) very satisfied: 51.4%, 2) satisfied: 31.9%, 3) dissatisfied: 8.3%, 4) very dissatisfied: 8.3%. c) The presence of complications was significantly associated with patients' satisfaction, reoperation rate and longer hospital stays (P<.001). Post operative complications were frequent. No predictors could be found to prevent these complications and optimize patient selection and appropriate timing of surgery. Patients with complications had a significantly higher reoperation rate, longer hospital stay and more dissatisfaction. The patients' satisfaction was negatively influenced by complication occurrence and not by the aesthetic results. Copyright © 2012 AEC. Published by Elsevier Espana. All rights reserved.

Selected patients, presenting for reoperative coronary surgery with patent internal thoracic arteries (ITAs), may benefit from techniques to salvage and reuse these ITA grafts. We have termed this practice the recycling of ITAs. The purpose of this study is to report our short-term and midterm results using various recycling techniques. Between April 1996 and February 2009, 60 patients underwent ITA recycling at our institution. Information regarding survival and cardiac events was obtained from a prospectively maintained, institutional database. Survival and freedom from major adverse cardiac events were calculated using Kaplan-Meier analysis. Mean follow-up duration was 60 ± 36 months. Mean age was 64 ± 9 years and the mean time to reoperation was 117 ± 68 months. The patent ITA served as an inflow for a composite Y graft in 39 patients and was distally reimplanted on the same coronary vessel in 9 patients. A combination of these two techniques was used in 8 patients. Other techniques were used in the remaining 4 patients. Freedom from cardiac death was 93% ± 7% and 85% ± 9% at 1 and 5 years and freedom from major adverse cardiac events was 93% ± 7% and 81% ± 11% at 1 and 5 years, respectively. Recycling of ITA grafts during reoperative coronary artery bypass grafting is safe and feasible in selected patients. These techniques can be useful in selected young patients to avoid saphenous vein graft or in patients with a lack of graft conduits. Copyright © 2011 The Society of Thoracic Surgeons.

In the current health care environment, cost effectiveness is critically important in policy setting and care of patients. This study performed a health economic analysis to assess the implications to providers and payers of expanding the use of frozen section margin analysis to minimize reoperations for patients undergoing breast cancer lumpectomy. A health care economic impact model was built to assess annual costs associated with breast lumpectomy procedures with and without frozen section margin analysis to avoid reoperation. If frozen section margin analysis is used in 20% of breast lumpectomies and under a baseline assumption that 35% of initial lumpectomies without frozen section analysis result in reoperations, the potential annual cost savings are $18.2 million to payers and $0.4 million to providers. Under the same baseline assumption, if 100% of all health care facilities adopted the use of frozen section margin analysis for breast lumpectomy procedures, the potential annual cost savings are $90.9 million to payers and $1.8 million to providers. On the basis of 10,000 simulations, use of intraoperative frozen section margin analysis yields cost saving for payers and is cost neutral to slightly cost saving for providers. This economic analysis indicates that widespread use of frozen section margin evaluation intraoperatively to guide surgical resection in breast lumpectomy cases and minimize reoperations would be beneficial to cost savings not only for the patient but also for payers and, in most cases, for providers.

The purpose of this study was to determine the quality and re-operation rate of the surgical treatment of ankle fractures at a large university hospital. X-rays and patient records of 137 patients surgically treated for ankle fractures were analyzed for: 1) correct classification according to Lauge-Hansen, 2) if congruity of the ankle joint was achieved, 3) selection and placement of the hardware, and 4) the surgeon's level of education. Totally 32 of 137 did not receive an optimal treatment, 11 were re-operated. There was no clear correlation between incorrect operation and the surgeon's level of education.

Right ventricular outflow tract (RVOT) aneurysm is a known complication of tetralogy of Fallot repair when a ventriculotomy is done. It leads to RV dysfunction and may require re-operation. We describe a rare instance of a patient who developed an RVOT aneurysm after trans-ventricular repair of tetralogy of Fallot, which was complicated with the formation of a thrombus in the aneurysm sac. The patient underwent re-operation with thrombectomy, excision of the RVOT aneurysm and pulmonary valve replacement. To the best of our knowledge, the occurrence of this combination and its implications have not been reported. PMID:22232231

The overall incidence of re-operation and prosthetic valve endocarditis was low in the present series as mechanical prostheses were used predominantly. The prosthetic dysfunctions were less frequent following the primary implantation with Bjork Shiley prostheses, but high operative risk was associated with the clotted Bjork Shiley prostheses. We also had unusual experience of strut fracture and sticking of Bjork Shiley discs in the closed position in both aortic and mitral positions. The early deaths were nil since the use of cardioplegic protection. Intra-operative bleeding due to adhesions can be minimised by using synthetic or heterologous pericardium during the primary operation.

To compare the safety and efficacy of hysteroscopic sterilization with the "Essure" device with laparoscopic sterilization in a large, all-inclusive, state cohort. Population based cohort study. Outpatient interventional setting in New York State. Women undergoing interval sterilization procedure, including hysteroscopic sterilization with Essure device and laparoscopic surgery, between 2005 and 2013. Safety events within 30 days of procedures; unintended pregnancies and reoperations within one year of procedures. Mixed model accounting for hospital clustering was used to compare 30 day and 1 year outcomes, adjusting for patient characteristics and other confounders. Time to reoperation was evaluated using frailty model for time to event analysis. We identified 8048 patients undergoing hysteroscopic sterilization and 44,278 undergoing laparoscopic sterilization between 2005 and 2013 in New York State. There was a significant increase in the use of hysteroscopic procedures during this period, while use of laparoscopic sterilization decreased. Patients undergoing hysteroscopic sterilization were older than those undergoing laparoscopic sterilization and were more likely to have a history of pelvic inflammatory disease (10.3% v 7.2%, P<0.01), major abdominal surgery (9.4% v 7.9%, P<0.01), and cesarean section (23.2% v 15.4%, P<0.01). At one year after surgery, hysteroscopic sterilization was not associated with a higher risk of unintended pregnancy (odds ratio 0.84 (95% CI 0.63 to 1.12)) but was associated with a substantially increased risk of reoperation (odds ratio 10.16 (7.47 to 13.81)) compared with laparoscopic sterilization. Patients undergoing hysteroscopic sterilization have a similar risk of unintended pregnancy but a more than 10-fold higher risk of undergoing reoperation compared with patients undergoing laparoscopic sterilization. Benefits and risks of both procedures should be discussed with patients for informed decisions making. © Mao et al 2015.

To assess the ability of the recently developed adult spinal deformity frailty index (ASD-FI) to predict odds of perioperative complications, odds of reoperation, and length of hospital stay after adult spinal deformity (ASD) surgery using a database other than the one used to create the index. We used the ASD-FI to calculate frailty scores for 266 ASD patients who had minimum postoperative follow-up of 2 years in the European Spine Study Group (ESSG) database. Patients were enrolled from 2012 through 2013. Using ASD-FI scores, we categorized patients as not frail (NF) (< 0.3 points), frail (0.3-0.5 points), or severely frail (SF) (> 0.5 points). Multivariable logistic regression, adjusted for preoperative and surgical factors such as operative time and blood loss, was performed to determine the relationship between ASD-FI category and odds of major complications, odds of reoperation, and length of hospital stay. We categorized 135 patients (51%) as NF, 90 patients (34%) as frail, and 41 patients (15%) as SF. Overall mean ASD-FI score was 0.29 (range 0-0.8). The adjusted odds of experiencing a major intraoperative or postoperative complication (OR 4.5, 95% CI 2.0-10) or having a reoperation (OR 3.9, 95% CI 1.7-8.9) were higher for SF patients compared with NF patients. Mean hospital stay was 2.1 times longer (95% CI 1.8-2.4) for SF patients compared with NF patients. Greater patient frailty, as measured by the ASD-FI, is associated with longer hospital stays and greater odds of major complications and reoperation.

Patients undergoing salvage laryngectomy are predisposed to radiation-induced hypothyroidism and impaired wound healing secondary to the tissue effects of prior treatment. The impact of hypothyroidism on postoperative wound healing is not established. A single-institution retrospective case series was performed. The inclusion criteria specified preoperatively euthyroid adults who underwent salvage laryngectomy with concurrent neck dissection between 1997 and 2015 for persistent or recurrent laryngeal squamous cell carcinoma after radiation or chemoradiation therapy (n = 182). The principal explanatory variable was postoperative hypothyroidism, defined as thyroid-stimulating hormone (TSH) higher than 5.5 mIU/L. The primary end points of the study were pharyngocutaneous fistulas and wounds requiring reoperation. Multivariate analysis was performed. The fistula rate was 47% among hypothyroid patients versus 23% among euthyroid patients. In the multivariate analysis, the patients who experienced hypothyroidism in the postoperative period had a 3.6-fold greater risk of fistula [95% confidence interval (CI) 1.8-7.1; p = 0.0002]. The hypothyroid patients had an 11.4-fold greater risk for a required reoperation (24.4 vs 5.4%) than the euthyroid patients (95% CI 2.6-49.9; p = 0.001). The risk for fistula (p = 0.003) and reoperation (p = 0.001) increased with increasing TSH. This corresponds to an approximate 12.5% incremental increase in the absolute risk for fistula and a 10% increase in the absolute risk for reoperation with each doubling of the TSH. Postoperative hypothyroidism independently predicts postoperative wound-healing complications. The association of hypothyroidism with fistula formation may yield opportunities to modulate wound healing with thyroid supplementation or to provide a biomarker of wound progression.

To assess the intraocular pressure control (IOP), changes in visual acuity, complications, reoperation rates and risk factors for failure following Ahmed glaucoma valve implantation in pediatric eyes with glaucoma. The medical records of consecutive patients with glaucoma who underwent Ahmed glaucoma valve implantation from January 2000 to December 2009) were retrospectively reviewed. Only one eye of each patient was included. Subgroup analysis was performed in three groups; group 1 included phakic eyes with primary congenital glaucoma, juvenile open-angle glaucoma, or glaucoma associated with ocular anomalies; group 2 included eyes with glaucoma in aphakia or pseudophakia; group 3 included eyes with other diagnoses. A successful outcome was defined as final IOP between 6 mm Hg and 18 mm Hg without loss of light perception or reoperation for glaucoma. A total of 71 eyes in 71 patients: 15 (21%) in group 1, 47 (66%) in group 2, and 9 (13%) in group 3 were included Successful IOP control was achieved in 44 eyes of 44 patients (62%). Cumulative probabilities of success by Kaplan-Meier analysis at 12 and 24 months was 97% and 80% for the entire group, 100% and 82% for group 1, 95% and 86% for group 2, and 90% and 42% for group 3. Reoperation was necessary for 18 patients (25%), either for tube-related complications or for IOP control. The only significant risk factor for failure was the category of diagnosis (P = 0.029). Ahmed glaucoma valve implantation is an option in the management of pediatric glaucoma; however, reoperations for tube related complications or for persistent elevated IOP is frequently needed.

Retrospective cohort study. To compare 30-day postoperative outcomes between patients undergoing outpatient and inpatient single-level cervical total disc replacement surgery. Cervical total disc replacement (TDR) is a motion sparing treatment for cervical radiculopathy and myelopathy. It is an alternative to anterior cervical discectomy and fusion (ACDF) with a similar complication rate. Like ACDF, it may be performed in the inpatient or outpatient setting. Efforts to reduce healthcare costs are driving spine surgery to be performed in the outpatient setting. As cervical total disc replacement surgery continues to gain popularity, the safety of treating patients on an outpatient basis needs to be validated. The National Surgical Quality Improvement Program (NSQIP) database was queried for patients who underwent single-level cervical disc replacement surgery between 2006-2015. Complication data including 30-day complications, reoperation rate, readmission rate, and length of stay data was compared between the inpatient and outpatient cohort using univariate analysis. There were 531 (34.2%) patients treated as outpatients and 1,022 (65.8%) were treated on an inpatient basis. The two groups had similar baseline characteristics. The overall 30-day complication rate was 1.4% for inpatients and 0.6% for outpatients. Reoperation rate was 0.6% for inpatient and 0.4% for outpatients. Readmission rate was 0.9% and 0.8% for inpatient and outpatient, respectively. There were no statistical differences identified in rates of readmission, reoperation, or complication between the inpatient and outpatient cohorts. There was no difference between 30-day complications, readmission and reoperation rates between inpatients and outpatients who underwent a single-level cervical total disc replacement. Furthermore, the overall 30-day complication rates were low. This study supports that single-level cervical TDR can be performed safely in an outpatient setting. 3.

High body mass index (BMI) is associated with increased rates of complications after total knee arthroplasty. To date, to our knowledge, studies have examined risk as a dichotomous variable using specific BMI thresholds. The purpose of this investigation was to quantify implant survival and the risk of common complications after total knee arthroplasty using BMI as a continuous variable. Using prospectively collected data from our institutional total joint registry, we analyzed 22,289 consecutive knees, in 16,136 patients, treated with primary total knee arthroplasty from 1985 to 2012. The mean BMI of these patients at the time of the surgical procedure was 31.3 kg/m (range, 11 to 69 kg/m). The Kaplan-Meier survival method was used to estimate survivorship, reoperations, and common complications, with associations of outcomes assessed using a Cox regression model. Utilizing smoothing spline parameterization, we found that reoperation (p < 0.001) and implant revision or removal rates (p < 0.001) increased with increasing BMI after total knee arthroplasty. Increasing BMI also was associated with increased rates of wound infection (hazard ratio [HR], 1.07; p < 0.001) and deep infection (HR, 1.08; p < 0.001) per unit of BMI over 35 kg/m. A BMI of 35 to 40 kg/m was associated with a higher rate of implant revision for aseptic loosening (p < 0.001) and for polyethylene wear (p < 0.001) compared with a BMI of 18 to 24.99 kg/m. There was no correlation between BMI and risk of venous thromboembolism, tibiofemoral instability, or need for knee manipulation. The rates of reoperation, implant revision or removal, and many common complications after total knee arthroplasty were strongly associated with BMI. Prognostic Level IV.

The purpose of this study was to evaluate survival and clinical outcome of the Scandinavian total ankle replacement (STAR) prosthesis after a minimum of ten years up to a maximum of 19 years. Fifty STAR prostheses in 46 patients with end stage ankle osteoarthritis operated between 1996 and 2006 by the same surgeon (MH) were included. Minimal follow-up was ten years (median 14.6 years, 95% confidence interval [CI] 12.9-16.4). Clinical (Kofoed score) and radiological assessments were taken before the operation and at one, ten (+2), and 16 (±3) years after implantation. The primary endpoint was defined as exchange of the whole prosthesis or conversion to arthrodesis (def. 1), exchange of at least one metallic component (def. 2), or exchange of any component including the inlay (due to breakage or wear) (def. 3). Survival was estimated according to Kaplan-Meier. Further reoperations related to STAR were also recorded. The ten year survival rate was (def. 1) 94% (CI 82-98%), (def. 2) 90% (CI, 77-96%), and (def. 3) 78% (CI 64-87%). The 19-year survival rate was (def. 1) 91% (CI 78-97%), (def. 2) 75% (CI 53-88%), and (def. 3) 55% (CI 34-71%). Considering any re-operations related to STAR, 52% (26/50) of prostheses were affected by re-operations. Mean pre-operative Kofoed score was 49, which improved to 84 after one year (n = 50), to 90 after ten years (n = 46), and to 89 after 16 years (n = 28). The survival rate for def. 1 and 2 was high. However, re-operations occurred in 52% of all STAR prosthesis. Retrospective cohort study, evidence Level 4.

Midline dorsal plication is an efficient and safe surgical technique to correct chordee. We investigated the efficacy of midline dorsal plication for recurrent chordee in complicated hypospadias reoperations. We retrospectively evaluated the charts of 25 boys who underwent reoperation between 1999 and 2004 due to complications of primary hypospadias repair other than meatal stenosis. A total of 15 cases were initially managed elsewhere for primary repair or complications. The etiology of recurrent chordee was defined at surgical correction. When recurrent chordee was noted a midline dorsal plication was performed. Of 25 patients 10 had previously undergone chordee repair. Nine of these patients were observed to have recurrent chordee and 1 had de novo chordee. A total of 10 patients had recurrent or delayed onset chordee. Mean patient age at primary repair was 6.28 years (range 1 to 33). Mean age at last operation for chordee was 15.9 years (range 4 to 66). Mean interval to recurrent chordee was 6 years (range 1 to 16), excluding a 66-year-old blind patient who did not know when recurrent chordee developed. Five patients had chordee recur before puberty at a mean interval of 2.6 years. Mean reoperation rate was 2.4 for recurrent chordee cases and 2.6 for chordee-free cases. Mean followup after midline dorsal plication for recurrent chordee repair was 22 months (range 8 to 56), while mean followup in pubertal and postpubertal cases was 20 months. No recurrence of chordee or surgery related morbidity was observed after recurrent chordee repair by midline dorsal plication. Chordee may recur during puberty following successful chordee repair. The midline dorsal plication technique is simple, efficient and safe even in patients who have undergone multiple surgeries for hypospadias and chordee repair.

Background There has been a trend toward limiting perioperative prophylactic antibiotics, based on research not conducted in plastic surgery patients. The authors’ university hospital instituted antibiotic prescribing guidelines based on the Surgical Care Improvement Project. An increased rate of surgical-site infections was noted in breast reconstruction patients. The authors sought to determine whether the change in antibiotic prophylaxis regimen affected rates of surgical-site infections. Methods A retrospective study compared patients undergoing breast reconstruction who received preoperative and postoperative prophylactic antibiotics with a group who received only a single dose of preoperative antibiotic. Type of reconstruction and known risk factors for implant infection were noted. Results Two hundred fifty patients were included: 116 in the pre–Surgical Care Improvement Project group and 134 in the Surgical Care Improvement Project group. The overall rate of surgical-site infections increased from 18.1 percent to 34.3 percent (p = 0.004). Infections requiring reoperation increased from 4.3 percent to 16.4 percent (p = 0.002). Multivariate logistic regression demonstrated that patients in the Surgical Care Improvement group were 4.74 times more likely to develop a surgical-site infection requiring reoperation (95 percent CI, 1.69 to 13.80). Obesity, history of radiation therapy, and reconstruction with tissue expanders were associated with increased rates of surgical-site infection requiring reoperation. Conclusions Withholding postoperative prophylactic antibiotics in prosthetic breast reconstruction is associated with an increased risk of surgical-site infection, reoperation, and thus reconstructive failure. The optimal duration of postoperative prophylactic antibiotic use is the subject of future study. PMID:22575852

The purpose of this study is to access the outcomes of aortic bypass graft placement in children. This is a retrospective review of all children having aortic bypass graft placement for aortic arch obstruction for the first time between 1982 and 2013 at a single institution. The actuarial survival and the freedom from aortic arch reoperation were calculated and compared between the groups. Seventy consecutive children underwent aortic bypass graft placements. The median age and body weight at the operation were 14 days and 3.6 kg. There were 7 early deaths, 6 late deaths, and 7 heart transplants during the median follow-up of 10.8 years (0.0-31.5 years). The actuarial transplant free survival was 64.7 % at 20 years and the freedom from aortic arch reoperation was 50.5 % at 10 years. Between the children younger than 1 year old and older than 1 year old, there were significant differences in actuarial transplant free survival (56.4 vs. 100 % at 15 years, p = 0.0042) and in the freedom from aortic arch reoperation (18.7 vs. 100 % at 10 years, p < 0.001). The children who received aortic bypass graft larger than 16 mm in size had no aortic arch reoperation at 15 years. The aortic bypass graft placement for aortic arch obstruction can be done with low mortality and morbidity for children who can receive bypass graft larger than 16 mm in size. However, it should be avoided for the neonates and infants except selected situations.

To compare functional and anatomical outcomes after idiopathic epiretinal membrane (ERM) peeling combined with phacoemulsification and intraocular lens implantation versus ERM peeling alone. A retrospective, non-randomised comparative case series study was conducted of 81 eyes from 79 patients who underwent ERM peeling at the Beth Israel Deaconess Medical Center between 2001 and 2010. Eyes that underwent combined surgery for ERM and cataracts (group 1) were compared with those that had ERM peeling alone (group 2) with respect to best-corrected visual acuity at 6 months and 1 year after surgery, postoperative central macular thickness (CMT) as measured on optical coherence tomography, and rates of complications, including elevated intraocular pressure (IOP), ERM recurrence and need for reoperation. Mean logMAR visual acuity improved significantly in both groups at 6 months (p<0.001) and 1 year (p<0.001) after surgery. There was no statistical difference between the two groups in visual acuity improvement at 6 months (p=0.108) or 1 year (p=0.094). Mean CMT of both groups also significantly decreased after surgery (p=0.002), with no statistical difference in CMT reduction between the two groups, but a trend toward less CMT reduction in group 1 (p=0.061). The rates of complications, including IOP elevation, ERM recurrence and frequency of reoperation, were similar in the two groups, with non-statistical trends toward greater ERM recurrence (p=0.084) and need for reoperation (p=0.096) in those that had combined surgery. Combined surgery for ERMs and cataracts may potentially be as effective as membrane peeling alone with respect to visual and anatomical outcomes. Further studies are necessary to determine if there may be greater ERM recurrence or need for reoperation after combined surgery.

To describe procedure-specific types, rates, and risk factors for postdischarge (PD) complications occurring within 30 days after 21 groups of inpatient general surgery procedures. Retrospective cohort study. American College of Surgeons National Surgical Quality Improvement Program 2005 through 2010 Participant Use Data Files. A total of 551,510 adult patients who underwent one of 21 groups of general surgery procedures in the inpatient setting. Postdischarge complications, reoperation, and mortality. Of 551,510 patients (mean age, 54.6 years), 16.7% experienced a complication; 41.5% occurred PD. Of the PD complications, 75.0% occurred within 14 days PD. Proctectomy (14.5%), enteric fistula repair (12.6%), and pancreatic procedures (11.4%) had the highest PD complication rates. Breast, bariatric, and ventral hernia repair procedures had the highest proportions of complications that occurred PD (78.7%, 69.4%, and 62.0%, respectively). For all procedures, surgical site complications, infections, and thromboembolic events were the most common. Occurrence of an inpatient complication increased the likelihood of a PD complication (12.5% vs 6.2% without an inpatient complication; P < .001). Compared with patients without a PD complication, those with a PD complication had higher rates of reoperation (4.6% vs 17.9%, respectively; P < .001) and death (2.0% vs 6.9%, respectively; P < .001) within 30 days after surgery; those whose PD complication was preceded by an inpatient complication had the highest rates of reoperation (33.7%) and death (24.7%) (all P < .001). After adjustment, PD complications were associated with procedure type, American Society of Anesthesiologists class higher than 3, and steroid use. The PD complication rates vary by procedure, are commonly surgical site related, and are associated with mortality. Fastidious, procedure-specific patient triage at discharge as well as expedited patient follow-up could improve PD outcomes.

The use of trabecular metal (TM) cups in revision surgery has increased worldwide during the last decade. Since the introduction of the TM cup in Sweden in 2006, this design has gradually replaced other uncemented designs used in Sweden. According to data from the Swedish Hip Arthroplasty Register (SHAR) in 2012, one-third of all uncemented first-time cup revisions were performed using a TM cup. We compared the risk of reoperation and re-revision for TM cups and the 2 other most frequently used cup designs in acetabular revisions reported to the SHAR. The hypothesis was that the performance of TM cups is as good as that of established designs in the short term. The study population consisted of 2,384 patients who underwent 2,460 revisions during the period 2006 through 2012. The most commonly used cup designs were the press-fit porous-coated cup (n = 870), the trabecular metal cup (n = 805), and the cemented all-polyethylene cup (n = 785). 54% of the patients were female, and the median age at index revision was 72 (19-95) years. Reoperation was defined as a second surgical intervention, and re-revision-meaning exchange or removal of the cup-was used as endpoint. The mean follow-up time was 3.3 (0-7) years. There were 215 reoperations, 132 of which were re-revisions. The unadjusted and adjusted risk of reoperation or re-revision was not significantly different for the TM cup and the other 2 cup designs. Our data support continued use of TM cups in acetabular revisions. Further follow-up is necessary to determine whether trabecular metal cups can reduce the re-revision rate in the long term, compared to the less costly porous press-fit and cemented designs.

OBJECTIVE Focal cortical dysplasia (FCD) is a common cause of medically intractable epilepsy that often may be treated by surgery. Following resection, many patients continue to experience seizures, necessitating a decision for further surgery to achieve the desired seizure outcomes. Few studies exist on the efficacy of reoperation for intractable epilepsy due to FCD in pediatric cohorts, including the definition of prognostic factors correlated with clinical benefit from further resection. METHODS The authors retrospectively analyzed the medical records and MR images of 22 consecutive pediatric patients who underwent repeat FCD resection after unsuccessful first surgery at the Children's National Health System between March 2005 and April 2015. RESULTS Accounting for all reoperations, 13 (59%) of the 22 patients achieved complete seizure freedom and another 5 patients (23%) achieved significant improvement in seizure control. Univariate analysis demonstrated that concordance in electrocorticography (ECoG) and MRI localization (p = 0.005), and completeness of resection (p = 0.0001), were associated with seizure freedom after the first reoperation. Patients with discordant ECoG and MRI findings ultimately benefited from aggressive multilobe lobectomy or hemispherectomy. Repeat lesionectomies utilizing intraoperative MRI (iMRI; n = 9) achieved complete resection and seizure freedom in all cases. CONCLUSIONS Reoperation may be clinically beneficial in patients with intractable epilepsy due to FCD. Patients with concordant intraoperative ECoG and MRI localization may benefit from extended resection of residual dysplasia at the margins of the previous lesional cavity, and iMRI may offer benefits as a quality control mechanism to ensure that a complete resection has been accomplished. Patients with discordant findings may benefit from more aggressive resections at earlier stages to achieve better seizure control and ensure functional plasticity.

Use of surgical safety checklists has been associated with significant reduction in postoperative surgical site infection (SSI), morbidity, and mortality. To evaluate the effectiveness of an intraoperative checklist in high-risk surgical patients in a high standard care environment with long-standing regular perioperative safety control programs. Quasi-experiment pre-post checklist implementation. Surgical patients above 16 years with an American Society of Anesthesiologists (ASA) score 3-5 operated upon at a large tertiary hospital. Unplanned return to operating room for any reason, reoperation for SSI, unplanned admission to intensive care unit, and in-hospital death within 30 days. A total of 609 patients (53% elective, 85% ASA 3, mean age 70 y) were included before and 1818 after implementation (52% elective, 87% ASA 3, mean age 69 y), the latter with 552, 558, and 708 in period I, II, and III, respectively. Comparing preimplementation to postimplementation periods: unplanned return to operating room occurred in 45/609 (7.4%) versus 109/1818 (6.0%) interventions [adjusted risk ratios (RR) 0.82; 95% confidence interval (CI), 0.59-1.14]; reoperation for SSI in 18/609 (3.0%) versus 109/1818 (1.7%) interventions (adjusted RR 0.56; 95% CI, 0.32-1.00); unplanned admission to intensive care unit in 17 (2.8%) versus 48 (2.6%) interventions (adjusted RR 0.90; 95% CI, 0.52-1.55); and in-hospital death occurred in 26 (4.3%) versus 108 (5.9%) patients (adjusted RR 1.44; 95% CI, 0.97-2.14). Checklist use during 77 interventions prevented 1 reoperation for SSI. A trend toward reduced reoperation rates for SSI was observed after checklist implementation in this high standard care environment; no influence on other outcome measures was observed.

The laparoscopic approach in colorectal complications is controversial because of its difficulty. However, it has been proven that it can provide advantages over open surgery. The aim of this study is to compare laparoscopic approach in reoperations for complications after colorectal surgery with the open approach taking into account the severity of the patient prior to reoperation. Patients who underwent laparoscopic colorectal surgery from January 2006 to December 2015 were retrospectively reviewed. Patients requiring urgent surgical procedures for complications in the postoperative period were divided in two groups: laparoscopic surgery (LS) and open surgery (OS). To control clinical severity prior to reoperation, The Mannheim Peritonitis Index (MPI) was calculated. A total of 763 patients were studied, 40 required urgent surgery (24 OS/16 LS). More ileostomies were performed in the LS group (68.7% vs. 29.2%) and more colostomies in the OS group (37.5% vs. 6.2%), p<0.05. MPI was higher in OS group (27.31±6.47 [19-35] vs. 18.36±7.16 [11-24], p<0.001). Hospital stay after re-intervention, oral tolerance and surgical wound infection, were favorable in LS (p<0.05 in all cases). In patients with MPI score ≤26, laparoscopic approach showed shorter hospital stay after re-intervention, less stay in the critical care unit after re-intervention, earlier start of oral tolerance and less surgical wound infection (p<0.05). A laparoscopic approach in re-intervention for complications after laparoscopic colorectal surgery associates a faster recovery reflected in a shorter hospital stay, earlier start of oral tolerance and a lower abdominal wall complication rate in patients with low severity index.

2011-05-01

Progressive kyphosis occurs in up to 20% of patients with myelomeningocele. Severely affected patients can develop recurrent skin breakdown, osteomyelitis, sitting imbalance, and poor cosmetic appearance. We (1) assessed the ability of kyphectomy to restore an intact skin envelope and allow comfortable seating in a wheelchair; (2) reviewed the complications of kyphectomy and spinal fusion in myelomeningocele; and (3) determined whether patients requiring unexpected reoperation had worse correction or more ulceration compared with those patients treated with a single surgery. We retrospectively reviewed the records of 23 children with thoracic-level myelomeningocele who were treated with kyphectomy and spinal fusion since 1980. Indications for surgery included recurrent skin breakdown (15 patients) and poor sitting balance or unacceptable cosmetic deformity (three patients). We evaluated operative technique, type of sacropelvic fixation, surgical complications, radiographic correction, and skin condition at followup. The minimum followup was 2 years (median, 4.1 years; range, 2.1-10 years); 18 of the 23 children had greater than 2 years followup and are reported here. Kyphectomy achieved a sitting balance and resolved in skin ulceration in 17 of 18 patients. Seven patients had complications requiring reoperation. Three patients had multiple reoperations for early deep infection and one patient each had reoperation for late infection, pseudarthrosis, implant-related sacral pressure sore, and planned extension of proximal fusion after growth. Patients requiring multiple operations had similar correction and relief of ulceration to those treated with a single procedure. Complications after kyphectomy are frequent and many children with myelomeningocele and severe hyperkyphosis require multiple procedures and lengthy hospital stays. Nonetheless, improved seating balance and resolution of skin problems was achieved in 17 of 18 patients.

To evaluate long-term results of aortic root procedures combined with ascending aorta replacement for aneurysms, using 4 surgical strategies. From January 1995 to January 2011, 957 patients underwent 1 of 4 aortic root procedures: valve preservation (remodeling or modified reimplantation, n = 261); composite biologic graft (n = 297); composite mechanical graft (n = 156); or allograft root (n = 243). Seven deaths occurred (0.73%), none after valve-preserving procedures, and 13 strokes (1.4%). Composite grafts exhibited higher gradients than allografts or valve preservation, but the latter 2 exhibited more aortic regurgitation (2.7% biologic and 0% mechanical composite grafts vs 24% valve-preserving and 19% allografts at 10 years). Within 2 to 5 years, valve preservation exhibited the least left ventricular hypertrophy, allograft replacement the greatest; however, valve preservation had the highest early risk of reoperation, allograft replacement the lowest. Patients receiving allografts had the highest risk of late reoperation (P < .05), and those receiving composite mechanical grafts and valve preservation had the lowest. Composite bioprosthesis patients had the highest risk of late death (57% at 15 years vs 14%-26% for the remaining procedures, P < .0001), because they were substantially older and had more comorbidities (P < .0001). These 4 aortic root procedures, combined with ascending aorta replacement, provide excellent survival and good durability. Valve-preserving and allograft procedures have the lowest gradients and best ventricular remodeling, but they have more late regurgitation, and likely, less risk of valve-related complications, such as bleeding, hemorrhage, and endocarditis. Despite the early risk of reoperation, we recommend valve-preserving procedures for young patients when possible. Composite bioprostheses are preferable for the elderly.

Partial atrioventricular septal defect (pAVSD) is routinely repaired with a low mortality. However, limited data are available on the long-term follow-up of these patients. The current study was designed to determine long-term survival and morbidity of a large cohort of patients operated on at a single institution. From 1975 to 2012, 249 consecutive patients underwent pAVSD repair at the Royal Children's Hospital. The follow-up data were obtained from hospital records, correspondence with cardiologists and primary care physicians, patient surveys and the state death registry. The early mortality rate was 1.2% (3/249), while the long-term survival rate was 96% (95% CI: 93-98%) at 10 years and 94% (95% CI: 89-97%) at 30 years. Freedom from reoperation was 84% at 10 years and 75% at 30 years. The most common reoperations were left atrioventricular valve surgery (30/249, 12.1%), resection of left ventricular outflow tract obstruction (12/249, 4.8%) and closure of residual atrial septal defects (5/249, 2.0%). Implantation of a permanent pacemaker was required in 3.2% (8/249) of patients. Despite a substantial reoperation rate, only 43% of patients older than 18 years of age were seen by a cardiologist within the most recent 2 years of the study period, compared with 80% of those younger than 18 years (P < 0.001). Repair of pAVSD is performed with a low mortality and excellent long-term survival. However, a substantial reoperation rate warrants close follow-up into adulthood. © The Author 2014.

to present our experience with scheduled reoperations in 15 patients with intra-abdominal sepsis. we have applied a more effective technique consisting of temporary abdominal closure with a nylon mesh sheet containing a zipper. We performed reoperations in the operating room under general anesthesia at an average interval of 84 hours. The revision consisted of debridement of necrotic material and vigorous lavage of the involved peritoneal area. The mean age of patients was 38.7 years (range, 15 to 72 years); 11 patients were male, and four were female. forty percent of infections were due to necrotizing pancreatitis. Sixty percent were due to perforation of the intestinal viscus secondary to inflammation, vascular occlusion or trauma. We performed a total of 48 reoperations, an average of 3.2 surgeries per patient. The mesh-zipper device was left in place for an average of 13 days. An intestinal ostomy was present adjacent to the zipper in four patients and did not present a problem for patient management. Mortality was 26.6%. No fistulas resulted from this technique. When intra-abdominal disease was under control, the mesh-zipper device was removed, and the fascia was closed in all patients. In three patients, the wound was closed primarily, and in 12 it was allowed to close by secondary intent. Two patients developed hernia; one was incisional and one was in the drain incision. the planned reoperation for manual lavage and debridement of the abdomen through a nylon mesh-zipper combination was rapid, simple, and well-tolerated. It permitted effective management of severe septic peritonitis, easy wound care and primary closure of the abdominal wall.

The use of interventional radiology has increased as the first-line management of complications after pancreatic resections. Patients in whom interventional radiology was performed were compared with those in whom interventional radiology was not performed as regards type of pancreatic resection, diagnosis, postoperative mortality and morbidity, postoperative pancreatic fistula postpancreatectomy haemorrhage, bile leakage, reoperation rate and length of hospital stay. Our aim was to evaluate the usefulness of interventional radiology in the treatment of complications after pancreatic resection. One hundred and eighty-two (62.8%) out of 290 patients experienced postoperative complications. Interventional radiology procedures were performed in 37 cases (20.3%): percutaneous drainage in 28, transhepatic biliary drainage in 8 and arterial embolisation in 3 cases. Technical success was obtained in all cases and clinical success in 75.7%. Reoperation was avoided in 86.5%. In patients with major complications, clinically relevant postoperative pancreatic fistula and bile leaks as well as those with late postpancreatectomy haemorrhage (P=0.030) and patients with postpancreatectomy haemorrhage grade C (P=0.029), interventional radiology was used (P<0.001, P<0.001 and P=0.009, respectively) significantly more frequently than in the remaining patients. The reoperation and mortality rates were similar in the two groups (P=0.885 and P=0.100, respectively) while patients treated with interventional radiology procedures had a significant longer length of hospital stay than those in the non-interventional radiology group (37.5 ± 23.4 vs. 18.7 ± 11.7 days; P<0.001). Interventional radiology procedures were useful, especially for patients with postoperative pancreatic fistulas and bile leaks in whom reoperation was very often avoided.

A 62-years-old female had undergone ascending aortic replacement with homograft for graft infection and mediastinitis after initial replacement of ascending aorta due to acute type A dissection. Ten years after homograft replacement, follow up computed tomography showed acute growing saccular aneurysm of the homograft without infectious symptoms. We urgently performed Bentall procedure and hemiarch replacement successfully. Pathological diagnosis was true aneurysm of the homograft. She was discharged from hospital without any complication and has been quite uneventful 7 years after surgery. True aneurysm of the homograft is very rare and our case is the 1st report of successful reoperation.

Rapid recovery protocols after total hip arthroplasty (THA) have been introduced worldwide in the last few years and they have reduced the length of hospital stay. We show the results of the introduction of a rapid recovery protocol for primary THA for unselected patients in our large teaching hospital. In a retrospective cohort study, we included all 1,180 patients who underwent a primary THA between July 1, 2008 and June 30, 2012. These patients were divided into 3 groups: patients operated before, during, and after the introduction of the rapid recovery protocol. There were no exclusion criteria. All complications, re-admissions, and reoperations were registered and analyzed. The mean length of hospital stay decreased from 4.6 to 2.9 nights after the introduction of the rapid recovery protocol. There were no statistically significant differences in the rate of complications, re-admissions, or reoperations between the 3 groups. In a large teaching hospital, the length of hospital stay decreased after introduction of our protocol for rapid recovery after THA in unselected patients, without any increase in complications, re-admissions, or reoperation rate.

Purpose To compare three year outcomes and complications of the Ahmed FP7 Glaucoma Valve (AGV) and Baerveldt 101–350 Glaucoma Implant (BGI) for the treatment of refractory glaucoma. Design Multicenter randomized controlled clinical trial. Participants 276 patients; 143 in the AGV group and 133 in the BGI group. Methods Patients aged 18–85 years with refractory glaucoma and intraocular pressures (IOPs) ≥18 mmHg in whom an aqueous shunt was planned were randomized to either an AGV or a BGI. Main Outcome Measures IOP, visual acuity, supplemental medical therapy, complications, and failure (IOP > 21 mmHg or not reduced by 20% from baseline, IOP ≤ 5 mmHg, reoperation for glaucoma or removal of implant, or loss of light perception vision). Results At 3 years, IOP (mean ± standard deviation) (SD) was 14.3 ± 4.7 mmHg (AGV group) and 13.1 ± 4.5 mmHg (BGI group) (p = 0.086) on 2.0 ± 1.4 and 1.5 ± 1.4 glaucoma medications respectively (p = 0.020). The cumulative probabilities of failure were 31.3% (standard error = 4.0%) (SE) (AGV) and 32.3% (4.2%) (BGI) (p = 0.99). Postoperative complications associated with reoperation or vision loss of ≥ 2 Snellen lines occurred in 24 patients (22%) (AGV) and 38 patients (36%) (BGI) (p = 0.035). The mean change in the Logarithm of the Minimum Angle of Resolution visual acuity (logMAR VA) at 3 years was similar (AGV: 0.21 ± 0.88, BGI: 0.26 ± 0.74) in the two treatment groups at 3 years (p=0.66). The cumulative proportion of patients (SE) undergoing reoperation for glaucoma prior to the three year postoperative time point was 14.5% (3.0%) in the AGV group compared to 7.6% (2.4%) in the BGI group (p=0.053, log-rank). The relative risk of reoperation for glaucoma in the AGV group was 2.1 times that of the BGI group (95% Confidence Interval:1.0–4.8, p=0.045; Cox proportional hazards regression). Conclusions AGV implantation was associated with the need for significantly greater adjunctive medication to achieve equal success relative to BGI implantation and resulted in a greater relative risk of reoperation for glaucoma. More subjects experienced serious postoperative complications in the BGI group than in the AGV group. PMID:24768240

Fracture fixation in the operative management of hip fractures (FAITH): an international, multicentre, randomised controlled trial

PubMed Central

2017-01-01

Summary Background Reoperation rates are high after surgery for hip fractures. We investigated the effect of a sliding hip screw versus cancellous screws on the risk of reoperation and other key outcomes. Methods For this international, multicentre, allocation concealed randomised controlled trial, we enrolled patients aged 50 years or older with a low-energy hip fracture requiring fracture fixation from 81 clinical centres in eight countries. Patients were assigned by minimisation with a centralised computer system to receive a single large-diameter screw with a side-plate (sliding hip screw) or the present standard of care, multiple small-diameter cancellous screws. Surgeons and patients were not blinded but the data analyst, while doing the analyses, remained blinded to treatment groups. The primary outcome was hip reoperation within 24 months after initial surgery to promote fracture healing, relieve pain, treat infection, or improve function. Analyses followed the intention-to-treat principle. This study was registered with ClinicalTrials.gov, number NCT00761813. Findings Between March 3, 2008, and March 31, 2014, we randomly assigned 1108 patients to receive a sliding hip screw (n=557) or cancellous screws (n=551). Reoperations within 24 months did not differ by type of surgical fixation in those included in the primary analysis: 107 (20%) of 542 patients in the sliding hip screw group versus 117 (22%) of 537 patients in the cancellous screws group (hazard ratio [HR] 0.83, 95% CI 0.63–1.09; p=0.18). Avascular necrosis was more common in the sliding hip screw group than in the cancellous screws group (50 patients [9%] vs 28 patients [5%]; HR 1.91, 1.06–3.44; p=0.0319). However, no significant difference was found between the number of medically related adverse events between groups (p=0.82; appendix); these events included pulmonary embolism (two patients [<1%] vs four [1%] patients; p=0.41) and sepsis (seven [1%] vs six [1%]; p=0.79). Interpretation In terms of reoperation rates the sliding hip screw shows no advantage, but some groups of patients (smokers and those with displaced or base of neck fractures) might do better with a sliding hip screw than with cancellous screws.

Diabetes mellitus confers an increased risk of hip fractures. There is a limited knowledge of how the outcome after a hip fracture in patients with diabetes affect Health Related Quality of Life (HRQoL). The primary aim of this study was to evaluate HRQoL. Secondary aims were reoperation rate, complications and functions in patients with diabetes followed for 2 years after a hip fracture. Out of 2133 patients diabetes was present in 234 patients (11%). Main outcome measurements were HRQoL evaluated with EuroQoL 5-Dindex score, reoperation rate, surgical and medical complications, function as walking ability, daily activities, living condition and pain. Preoperatively, patients with diabetes mellitus had more pain (p=0.044), co-morbidities, reduced health status (p=0.001) and more often used a walking frame (p=0.014) than patients without diabetes, whereas Katz ADL index, cognition and body mass index did not differ. There was no difference in fracture type, surgical method or reoperation between the two groups or between patients with insulin treated or oral treated diabetes. The EQ-5Dindex score decreased from 0.64 at admission to 0.45 at 4 months, 0.49 at 12 months and 0.51 at 24 months with similar results for patients with and without diabetes. During the first postoperative year there was not more medical complications among patients with diabetes, however cardiac (p=0.023) and renal failure (p=0.032) were more frequent in patients with diabetes at 24 months. Patients with diabetes more often had severe hip pain at 4 months (p=0.031). At 12 months more diabetic patients were living independently (p=0.034). There was no difference in walking ability, ADL and living condition between the groups at 24 months. The findings of this study indicate that patients with diabetes mellitus had more pain, co-morbidities, reduced health status preoperatively than patients without diabetes. Hip fracture patients with diabetes mellitus have more hip pain at 4 months. Cardiac and renal failure was more frequent in patients with diabetes at 24 months but otherwise we found a comparable re-operation rate, function and deterioration of Health Related Quality of Life as patients without diabetes within 2 years after a hip fracture.

To examine a case series of reoperations for deep brain stimulation (DBS) leads in which clinical scenarios revealed suboptimal outcome from a previous operation. Suboptimally placed DBS leads are one potential reason for unsatisfactory results after surgery for Parkinson's disease (PD), essential tremor (ET), or dystonia. In a previous study of patients who experienced suboptimal results, 19 of 41 patients had misplaced leads. Similarly, another report commented that lead placement beyond a 2- to 3-mm window resulted in inadequate clinical benefit, and, in 1 patient, revision improved outcome. The goal of the current study was to perform an unblinded retrospective chart review of DBS patients with unsatisfactory outcomes who presented for reoperation. Patients who had DBS lead replacements after reoperation were assessed with the use of a retrospective review of an institutional review board-approved movement disorders database. Cases of reoperation for suboptimal clinical benefit were included, and cases of replacement of DBS leads caused by infection or hardware malfunction were excluded. Data points studied included age, disease duration, diagnosis, motor outcomes (the Unified Parkinson Disease Rating Scale III in PD, the Tremor Rating Scale in ET, and the Unified Dystonia Rating Scale in dystonia), quality of life (Parkinson's Disease Questionnaire-39 in PD), and the Clinician Global Impression scale. The data from before and after reoperation were examined to determine the estimated impact of repeat surgery. There were 11 patients with PD, 7 with ET, and 4 with dystonia. The average age of the PD group was 52 years, the disease duration was 10 years, and the average vector distance of the location of the active DBS contact was adjusted 5.5 mm. Six patients (54%) with PD had preoperative off medication on DBS Unified Parkinson Disease Rating Scale scores that could be compared with postoperative off medication on DBS scores. The average improvement across this group of patients was 24.4%. The Parkinson's Disease Questionnaire-39 improved in the areas of mobility (28.18), activities of daily living (14.77), emotion (14.72), stigma (17.61), and discomfort (17.42). The average age of the ET group was 66 years, the disease duration was 29 years, and the average adjusted distance was 6.1 mm. Five ET patients (83.3%) in the cohort had a prereplacement on DBS Tremor Rating Scale and a postreplacement on DBS Tremor Rating Scale with the average improvement of 60.4%. The average age of the dystonia group was 39 years, the average disease duration was 7 years, and the average adjusted lead distance was 6.7 mm. Three patients (75%) with dystonia had prereplacement on DBS Unified Dystonia Rating Scale and postreplacement on DBS Unified Dystonia Rating Scale scores. Across these 3 dystonia patients, the improvement was 12.8%. Clinician Global Impression scale scores (1, very much improved; 2, much improved; 3, minimally improved; 4, no change; 5, minimally worse; 6, much worse; 7, very much worse) after replacement revealed the following results in patients with PD: 1, 7 patients; 2, 3 patients; 3, 1 patient); with ET (1, 4 patients; 2, 3 patients); and with dystonia (1, 1 patient; 2, 2 patients; 3, 1 patient). The latency from original lead placement to reoperation (repositioning/revision) overall was 28.9 months (range, 2-104 mo); however, in leads referred from outside institutions (n = 11 patients), this latency was 48 months (range, 12-104 mo) compared with leads implanted by surgeons from the University of Florida (n = 11 patients), which was 9.7 months (range, 2-19 mo). The most common clinical history was failure to achieve a perceived outcome; however, history of an asymmetric benefit was present in 4 (18.2%) of 22 patients, and lead migration was present in 3 (13.6%) of 22 patients. There are many potential causes of suboptimal benefit after DBS. Timely identification of suboptimal lead placements followed by reoperation and repositioning/replacement in a subset of patients may improve outcomes.

Conservative treatment of postoperative chylothorax: a case report.

Chylothorax is a well-documented complication of thoracic trauma and is associated with high rates of morbidity and mortality. Treatment for chylothorax includes conservative measures (total parenteral nutrition, pleural drainage, and pleurodesis) and surgery (thoracic duct ligation). We present the case of a 65-year-old man who developed chylothorax after an elective surgical procedure. In this report conservative treatment aims to reduce chyle flow, to drain the pleural cavity in an effective manner, and to prevent chronic sequelae. Optimal conservative treatment, started immediately upon diagnosis, effectively reduces the need for reoperation and long-term hospitalization, and it might prevent further sequelae of chylothorax. The chylothorax was successfully treated conservatively, which may reduce the need for reoperation.

Hip resurfacing is an alternative to total hip arthroplasty. We aimed to compare an experienced hip surgeon's initial clinical results of hip resurfacing with a new cementless total hip arthroplasty (THA). The first 55 consecutive hip resurfacing arthroplasties were compared to 100 consecutive cementless THAs using a cylindrical tapered femoral stem. The learning curve between the two procedures was compared utilizing the incidence of reoperation, complications, Harris Hip Scores (HHS), and implant survivorship. The reoperation rate was significantly higher (p = 0.019) for hip resurfacing (14.5%) versus THA (4%). The overall complication rate between the two groups was not significantly different (p = 0.398). Preoperative HHS were similar between the two groups (p = 0.2). The final mean HHS was similar in both the resurfacing and THA groups (96 vs. 98.3, respectively, p < 0.65). Kaplan-Meier survival analysis with an endpoint of reoperation suggests complications occurred earlier in the resurfacing group versus the THA group (log-rank test, p = 0.007). In comparison to our initial experience with a cementless THA stem, operative complications occur earlier and more often after hip resurfacing during the learning period. The clinical outcomes in both groups however are similar at 5 year follow-up.

Purpose: Although pannus overgrowth by itself was not the pathology of structural valve deterioration (SVD), it might be related to reoperation for SVD of the bioprostheses. Methods: We retrospectively reviewed patients undergoing reoperation for SVD after implantation of the third-generation Mosaic aortic bioprosthesis and macroscopic appearance of the explanted valves was examined to detect the presence of pannus. Results: There were 10 patients and the age for the initial aortic valve replacement was 72 ± 10 years old. The duration of durability was 9.9 ± 2.0 years. Deteriorated valve presented stenosis (valvular area of 0.96 ± 0.20 cm2; pressure gradient of 60 ± 23 mmHg). Coexisting regurgitant flow was detected in two cases. Macroscopically, subvalvular pannus overgrowth was detected in 8 cases (80%). The proportion of overgrowth from the annulus was almost even and pannus overgrowth created subvalvular membrane, which restricted the area especially for each commissure. In contrast, opening and mobility of each leaflet was not severely limited and pannus overgrowth would restrict the area, especially for each commissure. In other two cases with regurgitation, tear of the leaflet on the stent strut was detected and mild calcification of each leaflet restricted opening. Conclusion: In patients with the Mosaic aortic bioprosthesis, pannus overgrowth was the major cause for reoperation. PMID:26633541

To evaluate surgical outcome in a consecutive series of patients with conventional and robot assisted total laparoscopic hysterectomy. A retrospective cohort study was performed among patients with benign and malignant indications for a laparoscopic hysterectomy. Main surgical outcomes were operation room time and skin to skin operating time, complications, conversions, rehospitalisation and reoperation, estimated blood loss and length of hospital stay. A total of 294 patients were evaluated: 123 in the conventional total laparoscopic hysterectomy (TLH) group and 171 in the robot TLH group. After correction for differences in basic demographics with a multivariate linear regression analysis, the skin to skin operating time was a significant 18 minutes shorter in robot assisted TLH compared to conventional TLH (robot assisted TLH 92m, conventional TLH 110m, p0.001). The presence or absence of previous abdominal surgery had a significant influence on the skin to skin operating time as did the body mass index and the weight of the uterus. Complications were not significantly different. The robot TLH group had significantly less blood loss and lower rehospitalisation and reoperation rates. This study compares conventional TLH with robot assisted TLH and shows shorter operating times, less blood loss and lower rehospitalisation and reoperation rates in the robot TLH group.

Bowel obstructions following Roux-en-Y gastric bypass (RYGB) are a significant issue often caused by internal herniation. Controversy continues as to whether mesenteric defect closure is necessary to decrease the incidence of internal hernias after RYGB. Our purpose was to evaluate the effectiveness of closing the mesenteric defect at the jejunojejunostomy in patients who underwent RYGB by examining this potential space at reoperation for any reason. We retrospectively reviewed medical records of patients undergoing surgery after RYGB from August 1999 to October 2008 to determine the status of the mesentery at the jejunojejunostomy. Eighteen patients underwent surgery 2 to 19 months after open (n=8) or laparoscopic (n=10) RYGB. All patients had documented suture closure of their jejunojejunostomy at the time of RYGB. Permanent (n=12) or absorbable (n=6) sutures were used for closures. Patients lost 23.6 kg to 62.1 kg before a reoperation was required for a ventral hernia (n=8), cholecystectomy (n=4), abdominal pain (n=4), or small bowel obstruction (n=2). Fifteen of the 18 patients had open mesenteric defects at the jejunojejunostomy despite previous closure; none were the cause for reoperation. Routine suture closure of mesenteric defects after RYGB may not be an effective permanent closure likely due to the extensive fat loss and weight loss within the mesentery.

Surgical site infections (SSIs) are a leading cause of post-operative morbidity and mortality. We developed Clean Cut, a surgical infection prevention program, with two goals: (1) Increase adherence to evidence-based peri-operative infection prevention standards and (2) establish sustainable surgical infection surveillance. Here we describe our infection surveillance strategy. Clean Cut was piloted and evaluated at a 523 bed tertiary hospital in Ethiopia. Infection prevention standards included: (1) Hand and surgical site decontamination; (2) integrity of gowns, drapes, and gloves; (3) instrument sterility; (4) prophylactic antibiotic administration; (5) surgical gauze tracking; and (6) checklist compliance. Primary outcome measure was SSI, with secondary outcomes including other infection, re-operation, and length of stay. We prospectively observed all post-surgical wounds in obstetrics over a 12 day period and separately recorded post-operative complications using chart review. Simultaneously, we reviewed the written hospital charts after patient discharge for all patients whose peri-operative adherence to infection prevention standards was captured. Fifty obstetric patients were followed prospectively with recorded rates of SSI 14%, re-operation 6%, and death 2%. Compared with direct observation, chart review alone had a high loss to follow-up (28%) and decreased capture of infectious complications (SSI [n = 2], endometritis [n = 3], re-operations [n = 2], death [n = 1]); further, documentation inconsistencies failed to capture two complications (SSI [n = 1], mastitis [n = 1]). Concurrently, 137 patients were observed for peri-operative infection prevention standard adherence. Of these, we were able to successfully review 95 (69%) patient charts with recorded rates of SSI 5%, re-operation 1%, and death 1%. Patient loss to follow-up and poor documentation of infections underestimated overall infectious complications. Direct, prospective follow-up is possible but requires increased time, clinical skill, and training. For accurate surgical infection surveillance, direct follow-up of patients during hospitalization is essential, because chart review does not accurately reflect post-operative complications.

In unstable trochanteric fractures, the extramedullary rotationally stable screw-anchor (RoSA) combines the benefits of the load and rotational stability of the blade with the advantages of the screw (pull-out resistance, compression capability) in a single load carrier, and was designed to prevent femoral neck shortening by using an additional locked trochanteric stabilizing plate (TSP). The aim of the current prospective cohort study was the clinical evaluation of the RoSA/TSP system regarding the mechanical re-operation rate and the amount of postoperative femoral neck shortening. From September 2011 to January 2014 80 patients with unstable trochanteric fractures underwent internal extramedullary fixation with the RoSA/TSP (Königsee Implantate GmbH, Allendorf, Germany). Due to fracture stability and after induction of compression, additional long locked antitelescoping screws (AT, n = 1-4) were placed reaching the femoral head. Radiological (femoral neck shortening) and clinical re-examination of patients (n = 61) was performed 6-10 weeks and 6-10 months later. In the 61 re-examined patients (76 %) femoral neck shortening was very low with 2 mm 6-10 months after operation. Re-operations occurred in 8 % (n = 6) and in 4 % (n = 3) as prophylactic surgical intervention. Whereas one-third (4 %) of re-operations occurred due to iatrogenic surgical problems from the first operation two-thirds of patients (8 %) had a re-operation due to delay of bone union (3× nonunion, 3 planned removals of AT-screws to improve healing). The in-hospital mortality was 3 % (n = 2). The fixation of unstable trochanteric femur fractures using the RoSA/TSP in a first clinical setting led to a great primary stability, with significant advantages with regard to limited femoral neck shortening. However, the rigidity of the construct with its consequences regarding bone healing can be challenging for the surgeon. Nevertheless, in some cases of revision it could be beneficial for stability.

Prosthetic valve endocarditis is the most severe form of infective endocarditis. This study assessed the risks and challenges of surgery for aortic prosthetic valve endocarditis. In total, 116 consecutive patients (98 males, age 65.2±12.7years), who underwent redo-surgery for active aortic prosthetic valve endocarditis between 2000 and 2014, were reviewed. Cox regression analysis was used to identify factors for aortic root destructions as well as for morbidity and mortality. Median follow-up was 3.8 years (0-13.9 years). Aortic root destructions (42 limited and 29 multiple lesions) were associated with early prosthetic valve endocarditis and delayed diagnosis (≥14 d), but not with mortality. There were 16 (13.8%) early (≤30 d) and 32 (27.6%) late (>30 days) deaths. Survival at 1, 5, and 10 years was 72±4.3%, 56±5.4%, and 46±6.4%, respectively. The cumulative incidence of death, reinfection, and reoperation was 19.0% at 30days and 36.2% at 1year. Delayed diagnosis, concomitant procedures, and EuroSCORE II >20% were predictors for early mortality and need for mechanical circulatory support, age >70years, and critical preoperative state were predictors for late mortality. In their absence, survival at 10 years was 70±8.4%. Reinfections and reoperations occurred more frequently if ≥1 risk factor for endocarditis and aortic root destructions were present. At 10 years, freedom from reinfection and reoperation was 89±4.2% and 91±4.0%. The risks of death, reinfection, and reoperation are significant within the first year after surgery for aortic prosthetic valve endocarditis. Early diagnosis and aortic root destructions are the most important challenges, but advanced age, critical preoperative state, and the need for mechanical circulatory support determine long-term survival.

2012-09-01

The radiologic evaluation of Hirschsprung disease is well described in the literature. However, there is a paucity of literature describing the appearance of the neo-rectum and colon after repair, specifically describing findings in patients with poor functional outcome, which would suggest the need for reoperation. We describe findings on contrast enema and correlate them with surgical findings at reoperation in children with poor functional outcome after primary repair for Hirschsprung disease who suffer from bowel dysfunction that can manifest with either soiling or obstructive symptoms such as enterocolitis. Children were identified from our colorectal surgery database. At the time of abstract submission, 35 children had contrast enemas prior to reoperation. Additional children continue to present for evaluation. The majority of children included in the study had their primary repair performed elsewhere. The initial procedures included: Duhamel (n = 11), Soave (n = 20) or Swenson (n = 3). One child had undergone a primary Soave repair and subsequently had a Swenson-type reoperation but continued to have a poor outcome. One child's initial surgical repair could not be determined. Images were reviewed by a staff pediatric radiologist and a pediatric radiology fellow. Findings encountered on contrast enema in these children include a distal narrowed segment due to stricture or aganglionic/transitional zone segment (8), dilated/hypomotile distal segment (7), thickened presacral space due to compressing Soave cuff (11), dilated Duhamel pouch (8), active enterocolitis (3) and partially obstructing twist of the pull-through segment (1). Multiple anatomical and pathological complications exist that can lead to bowel dysfunction in children after repair of Hirschsprung disease. Little recent literature exists regarding the radiographic findings in children. We had the opportunity to review a substantial series of these children, describe the contrast enema findings in these difficult cases and correlate them with operative findings. Radiologic evaluation is key to assessing such patients; it defines the potential anatomical problem with the pull-through and facilitates surgical planning.

The Outcomes of Nonelongating Intramedullary Fixation of the Lower Extremity for Pediatric Osteogenesis Imperfecta Patients: A Meta-analysis.

PubMed

Scollan, Joseph P; Jauregui, Julio J; Jacobsen, Christina M; Abzug, Joshua M

Osteogenesis imperfecta is usually due to autosomal dominant mutations in type I collagen, leading to an increase in fractures and bone deformities, especially in the long bones of the lower extremities. The use of nonelongating intramedullary rods is an established surgical intervention to address such deformities. The rate of surgical complications has been reported to be as high as 187%, with revision rates as high as 90%, although exact global rates are unknown. As such, we sought to determine the published rates of (1) bone-related complications (including both fracture and deformity), (2) rod migration, and (3) complications that require reoperation. Following the Preferred Reporting Items for Systematic reviews and Meta-analyses (PRISMA) guidelines, 1295 studies were evaluated. After cross-referencing, and applying specific inclusion and exclusion criteria, a total of 7 studies were included in the final cohort. Data were extracted from the studies and analyzed. Random effect models determined the complication rates of intramedullary nonelongating rod procedures. A total of 359 primary nonelongating intramedullary rod procedures of tibiae and femurs, in patients with a mean age of 6 years (5.2 to 7.3 y), at a mean follow-up of 63 months (24 to 118 mo), were evaluated. 60% of the surgical procedures were on femurs, and 40% were on tibiae. The reoperation rate was 39.4%. The most common complication was rod migration, with a rate of 25.7%. The rate of bone-related complications was 19.5% including fractures (15.0%) and worsening bone deformity (4.3%). This is the first meta-analysis to identify the rates of complication and reoperation in lower limb intramedullary fixation for pediatric osteogenesis imperfecta patients. This study has shown that rod migration is the most common complication, followed by bone-related complications including fractures and deformity. Reoperations occur after nearly 40% of all procedures due to rod migration or bone-related complications. Level IV-retrospective meta-analysis.

Should patients with Björk-Shiley valves undergo prophylactic replacement?

About 85,000 patients have undergone replacement of diseased heart valves with prosthetic Björk-Shiley convexo-concave (CC) valves. These valves are prone to fracture of the outlet strut, which leads to acute valve failure that is usually fatal. Should patients with these valves undergo prophylactic replacement to avoid fracture? The incidence of strut fracture varies between 0% and 1.5% per year, depending on valve opening angle (60 degrees or 70 degrees), diameter (less than 29 mm or greater than or equal to 29 mm), and location (aortic or mitral). Other factors include the patient's life expectancy and the expected morbidity and mortality associated with reoperation. We have used decision analysis to identify the patients most likely to benefit from prophylactic reoperation. The incidence of outlet strut fracture was estimated from the data of three large studies on CC valves, and stratified by opening angle, diameter, and location. A Markov decision analysis model was used to estimate life expectancy for patients undergoing prophylactic valve replacement and for those not undergoing reoperation. Prophylactic valve replacement does not benefit patients with CC valves that have low strut fracture risks (60 degrees aortic valves and less than 29 mm, 60 degrees mitral valves). For most patients with CC valves that have high strut fracture risks (greater than or equal to 29 mm, 70 degrees CC), prophylactic valve replacement increases life expectancy. However, elderly patients with such valves benefit from prophylactic reoperation only if the risk of operative mortality is low. Patient age and operative risk are most important in recommendations for patients with CC valves that have intermediate strut fracture risks (less than 29 mm, 70 degrees valves and greater than or equal to 29 mm, 60 degrees mitral valves). For all patients and their doctors facing the difficult decision on whether to replace CC valves, individual estimates of operative mortality risk that take account of both patient-specific and institution-specific factors are essential.

Anterior cruciate ligament reconstructions (ACLRs) in skeletally immature patients are increasing. The purpose of this study is to describe the demographics, graft usage, revision, and re-operation rates in skeletally immature ACLRs in the Kaiser Permanente healthcare system. Skeletally immature patients (<17.0 years old with open physes) were identified using the Kaiser Permanente ACLR registry. Multi-ligament reconstructions and physeal-sparing ACLRs were excluded. Aseptic revision and same-knee re-operation were the outcomes of interest. Exposure of interest was graft type; bone-patellar-tendon-bone (BPTB) autograft, hamstring autograft, and any type of allograft. Age, gender, body mass index (BMI), and race were evaluated as confounders. Cox proportional hazard models stratified by surgeon were used to analyse the risk of revision and re-operation. A total of 534 primary ACLR cases were evaluated with a mean follow-up of 2.9 years. The majority were hamstring autografts (n = 388, 72.7%), male (n = 339, 63.9%), and White (n = 232, 43.4%). Median age was 14.9 years, and median BMI was 21.9 kg/m(2). There were 44 (8.2%) aseptic revisions and 48 (9.0%) same-knee re-operations. The incidence rate for revision was BPTB autograft 5.5%, hamstring autograft 7.5%, and allograft 13.2%. After adjusting for confounders and surgeon clustering effect, the risk of aseptic revision and revision between allograft and hamstring autograft did not reach statistical significance. Graft selection differs in skeletally immature patients with a preponderance of surgeries being performed with hamstring tendon autografts. High revision rates were identified for all graft types used, though differences in revision rates across different graft types did not reach statistical significance. Surgeons should be aware of high rates of revision in this skeletally immature young population, although type of graft used did not appear to make a difference. III.

Objective To compare the safety and efficacy of hysteroscopic sterilization with the “Essure” device with laparoscopic sterilization in a large, all-inclusive, state cohort. Design Population based cohort study. Settings Outpatient interventional setting in New York State. Participants Women undergoing interval sterilization procedure, including hysteroscopic sterilization with Essure device and laparoscopic surgery, between 2005 and 2013. Main outcomes measures Safety events within 30 days of procedures; unintended pregnancies and reoperations within one year of procedures. Mixed model accounting for hospital clustering was used to compare 30 day and 1 year outcomes, adjusting for patient characteristics and other confounders. Time to reoperation was evaluated using frailty model for time to event analysis. Results We identified 8048 patients undergoing hysteroscopic sterilization and 44 278 undergoing laparoscopic sterilization between 2005 and 2013 in New York State. There was a significant increase in the use of hysteroscopic procedures during this period, while use of laparoscopic sterilization decreased. Patients undergoing hysteroscopic sterilization were older than those undergoing laparoscopic sterilization and were more likely to have a history of pelvic inflammatory disease (10.3% v 7.2%, P<0.01), major abdominal surgery (9.4% v 7.9%, P<0.01), and cesarean section (23.2% v 15.4%, P<0.01). At one year after surgery, hysteroscopic sterilization was not associated with a higher risk of unintended pregnancy (odds ratio 0.84 (95% CI 0.63 to 1.12)) but was associated with a substantially increased risk of reoperation (odds ratio 10.16 (7.47 to 13.81)) compared with laparoscopic sterilization. Conclusions Patients undergoing hysteroscopic sterilization have a similar risk of unintended pregnancy but a more than 10-fold higher risk of undergoing reoperation compared with patients undergoing laparoscopic sterilization. Benefits and risks of both procedures should be discussed with patients for informed decisions making. PMID:26462857

OBJECTIVE The aims of this study were to evaluate a multiyear experience with subdural evacuating port system (SEPS) placement for chronic subdural hematoma (cSDH) in the intensive care unit at a tertiary neurosurgical center and to compare SEPS placement with bur hole evacuation in the operating room. METHODS All cases of cSDH evacuation were captured over a 7-year period at a tertiary neurosurgical center within an integrated health care delivery system. The authors compared the performance characteristics of SEPS and bur hole placement with respect to recurrence rates, change in recurrence rates over time, complications, length of stay, discharge disposition, and mortality rates. RESULTS A total of 371 SEPS cases and 659 bur hole cases were performed (n = 1030). The use of bedside SEPS placement for cSDH treatment increased over the 7-year period, from 14% to 80% of cases. Reoperation within 6 months was higher for the SEPS (15.6%) than for bur hole drainage (9.1%) across the full 7-year period (p = 0.002). This observed overall difference was due to a higher rate of reoperation during the same hospitalization (7.0% for SEPS vs 3.2% for bur hole; p = 0.008). Over time, as the SEPS procedure became more common and modifications of the SEPS technique were introduced, the rate of in-hospital reoperation after SEPS decreased to 3.3% (p = 0.02 for trend), and the difference between SEPS and bur hole recurrence was no longer significant (p = 0.70). Complications were uncommon and were similar between the groups. CONCLUSIONS Overall performance characteristics of bedside SEPS and bur hole drainage in the operating room were similar. Modifications to the SEPS technique over time were associated with a reduced reoperation rate.

On March 9, 2012, the Food and Drug Administration (FDA) approved Sientra's premarket approval application for its portfolio of silicone gel breast implants based on their review of Sientra's 3-year study data from the largest pivotal silicone gel breast implant study to date. This included the first approval of shaped breast implants in the United States. The authors provide an update to the 8-year safety and effectiveness of the Sientra High-Strength silicone gel breast implants. The Sientra Core study is an ongoing 10 year open-label, prospective, multi-center clinical study, which includes 1788 patients implanted with 3506 Sientra implants across four indications (Primary Augmentation, Revision Augmentation, Primary Reconstruction, and Revision Reconstruction). For the safety analysis, the incidence of post-operative complications, including all breast implant-related adverse effects (eg, infection, asymmetry), was estimated based on Kaplan-Meier risk rates. The effectiveness analyses include surgeon and patient satisfaction and changes in bra/cup size. Through 8 years, the overall risk of rupture was 4.6%, the risk of capsular contracture was 11.8% (rates were lower when using True Texture™), and the risk of reoperation was 28.3%. Out of the 580 reoperations in 456 patients, over half of all reoperations were due to cosmetic reasons (n = 299). The most common reasons for reoperation were capsular contracture (19.0%), style and/or size change (18.4%), and asymmetry (8.8%). Patient satisfaction remains high through 8 years, with 87% indicating that their breast implants make them feel more feminine than prior to enrollment. Safety data from the FDA Core study continues to support a comprehensive safety and effectiveness profile of Sientra's portfolio of round and shaped implants through 8 years. 3 Therapeutic. © 2015 The American Society for Aesthetic Plastic Surgery, Inc.

Objective: To summarize the experience of reoperations on patients who had late complications related to previous aortic surgery for Stanford type A dissection. Methods: From August 2008 to October 2016, 14 patients (10 male and 4 female patients) who underwent previous cardiac surgery for Stanford type A aortic dissection accepted reoperations on the late complications at Department of Thoracic and Cardiovascular Surgery, Nanjing Hospital Affiliated to Nanjing Medical University. The range of age was from 41 to 76 years, the mean age was (57±12) years. In these patients, first time operations were ascending aorta replacement procedure in 3 patients, ascending aorta combined with partial aortic arch replacement in 4 patients, aortic root replacement (Bentall) associated with Marfan syndrome in 3 patients, aortic valve combined with ascending aorta replacement (Wheat) in 1 patient, ascending aorta combined with Sun's procedure in 1 patient, Wheat combined with Sun's procedure in 1 patient, Bentall combined with Sun's procedure in 1 patient. The interval between two operations averaged 0.3 to 10.0 years with a mean of (4.8±3.1) years. The reasons for reoperations included part anastomotic split, aortic valve insufficiency, false aneurysm formation, enlargement of remant aortal and false cavity. The selection of reoperation included anastomotic repair, aortic valve replacement, total arch replacement and Sun's procedure. Results: Of the 14 patients, the cardiopulmonary bypass times were 107 to 409 minutes with a mean of (204±51) minutes, cross clamp times were 60 to 212 minutes with a mean of (108±35) minutes, selective cerebral perfusion times were 16 to 38 minutes with a mean of (21±11) minutes. All patients survived from the operation, one patient died from severe pulmonary infection 50 days after operation. Three patients had postoperative complications, including acute renal failure of 2 patients and pulmonary infection of 1 patient, and these patients were recovered after treatment. Thirteen patients were finally recovered from hospital. The patients were followed up for 16 to 45 months, and no aortic rupture, paraplegia and death were observed in the follow-up. Conclusions: Patients for residual aortic dissection after initial operations on Stanford type A aortic dissection should be attached great importance and always need emergency surgery, but the technique is demanding and risk is great for surgeons and patients, which need enough specification and accurate on aortic operation. More importantly, the Sun's procedure also should be performed on the treatment of residual aortic dissection or distal arch expansion, and obtains the short- and long-term results in the future.

Fracture fixation in the operative management of hip fractures (FAITH): an international, multicentre, randomised controlled trial.

PubMed

2017-04-15

Reoperation rates are high after surgery for hip fractures. We investigated the effect of a sliding hip screw versus cancellous screws on the risk of reoperation and other key outcomes. For this international, multicentre, allocation concealed randomised controlled trial, we enrolled patients aged 50 years or older with a low-energy hip fracture requiring fracture fixation from 81 clinical centres in eight countries. Patients were assigned by minimisation with a centralised computer system to receive a single large-diameter screw with a side-plate (sliding hip screw) or the present standard of care, multiple small-diameter cancellous screws. Surgeons and patients were not blinded but the data analyst, while doing the analyses, remained blinded to treatment groups. The primary outcome was hip reoperation within 24 months after initial surgery to promote fracture healing, relieve pain, treat infection, or improve function. Analyses followed the intention-to-treat principle. This study was registered with ClinicalTrials.gov, number NCT00761813. Between March 3, 2008, and March 31, 2014, we randomly assigned 1108 patients to receive a sliding hip screw (n=557) or cancellous screws (n=551). Reoperations within 24 months did not differ by type of surgical fixation in those included in the primary analysis: 107 (20%) of 542 patients in the sliding hip screw group versus 117 (22%) of 537 patients in the cancellous screws group (hazard ratio [HR] 0·83, 95% CI 0·63-1·09; p=0·18). Avascular necrosis was more common in the sliding hip screw group than in the cancellous screws group (50 patients [9%] vs 28 patients [5%]; HR 1·91, 1·06-3·44; p=0·0319). However, no significant difference was found between the number of medically related adverse events between groups (p=0·82; appendix); these events included pulmonary embolism (two patients [<1%] vs four [1%] patients; p=0·41) and sepsis (seven [1%] vs six [1%]; p=0·79). In terms of reoperation rates the sliding hip screw shows no advantage, but some groups of patients (smokers and those with displaced or base of neck fractures) might do better with a sliding hip screw than with cancellous screws.

Samraj, K; Gurusamy, K S

2007-10-17

The nature and indications for thyroid surgery vary and a perceived risk of haemorrhage post-surgery is one reason why wound drains are frequently inserted. However when a significant bleed occurs, wound drains may become blocked and the drain does not obviate the need for surgery or meticulous haemostasis. The evidence in support of the use of drains post-thyroid surgery is unclear therefore and a systematic review of the best available evidence was undertaken. To determine the effects of inserting a wound drain during thyroid surgery, on wound complications, respiratory complications and mortality. We searched the following databases: Cochrane Wounds Group Specialised Register and the Cochrane Central Register of Controlled Trials (CENTRAL) (issue 1, 2007); MEDLINE (2005 to February 2007); EMBASE (2005 to February 2007); CINAHL (2005 to February 2007) using relevant search strategies. Only randomised controlled trials were eligible for inclusion. Quasi randomised studies were excluded. Studies with participants undergoing any form of thyroid surgery, irrespective of indications, were eligible for inclusion in this review. Studies involving people undergoing parathyroid surgery and lateral neck dissections were excluded. At least 80% follow up (till discharge) was considered essential. Studies were assessed for eligibility and data were extracted by two authors independently, differences were resolved by discussion. Studies were assessed for validity including criteria on whether they used a robust method of random sequence generation and allocation concealment. Missing and unclear data were resolved by contacting the study authors. 13 eligible studies were identified (1646 participants). 11 studies compared drainage with no drainage and found no significant difference in re-operation rates; incidence of respiratory distress and wound infections. Post-operative wound collections needing aspiration or drainage were significantly reduced by drains (RR 0.51, 95% CI 0.27 to 0.97), but a further analysis of the 4 high quality studies showed no significant difference (RR 1.82, 95% CI 0.51 to 6.46). Hospital stay was significantly prolonged in the drain group (WMD 1.18 days, 95% CI 0.73 to 1.63).Eleven studies compared suction drain with no drainage and found no significant difference in re-operation rates; incidence of respiratory distress and wound infection rates. The incidence of collections that required aspiration or drainage without formal re-operation was significantly less in the drained group (RR 0.48, 95% CI 0.25 to 0.92). However, further analysis of only high quality studies showed no significant difference (RR 1.78, 95% CI 0.44 to 7.17). Hospital stay was significantly prolonged in the drain group (WMD 1.20 days, 95% CI 0.77 to 1.63). One study compared open drain with no drain. No participant in either group required re-operation. No data were available regarding the incidence of respiratory distress, wound infection and pain. The incidence of collections needing aspiration or drainage without re-operation was not significantly different between the groups and there was no significant difference in length of hospital stay. One study compared suction drainage with passive closed drainage. None of the participants in the study needed re-operation and data regarding other outcomes were not available. Two studies (180 participants) compared open drainage with suction drainage. One study reported wound infections and minor wound collections, both were not significantly different. The other study reported wound collections requiring intervention and hospital stay; both were not significantly different. None of the participants in either study required re-operation. Data regarding other outcomes were not available. There is no clear evidence that using drains in patients undergoing thyroid operations significantly improves patient outcomes and drains may be associated with an increased length of hospital stay. The existing evidence is from trials involving patients having goitres without mediastinal extension, normal coagulation indices and the operation not involving any lateral neck dissection for lymphadenectomy.

Two patients with Björk Shiley mitral valve replacement had migration and embolization of the occluding disc. One patient suffered migration of the disc a few hours after surgery and the other had a strut fracture with disc translocation six years after the initial operation. Clinical signs in both cases were pulmonary edema, cardiogenic shock, and absence of prosthetic sounds. Both patients were reoperated on an emergency basis, recovering after a complicated postoperative course. They are on functional Class I, 8 and 1 years later, respectively, with their dislodged discs still in the abdominal aorta. The only hope for survival in these patients is emergency reoperation, once the prosthetic mitral valve dysfunction is confirmed.

2014-09-01

The TVT-Secur was introduced in 2006 as a less invasive alternative to retropubic and transobturator suburethral slings. This retrospective cohort study evaluated objective and subjective results in a series of 158 consecutive patients as well as complications and the reoperation rate after TVT-Secur procedure. Between November 2006 and June 2010 a total of 158 patients underwent a TVT-Secur procedure at a single institution. All patients underwent preoperative urodynamic testing. All patients were invited for follow-up including physical examination, urodynamic studies and subjective evaluation. A total of 96 patients (61%) were available for follow-up with a mean follow-up of 29.8 months (range 5-50, median 30). At follow-up, eight (8%) of 96 patients had reoperations for stress incontinence. There were no reoperations for bleeding/hematoma, tape erosions or obstructed micturition and there were no tape erosions or exposures. 29 patients (30%) had a negative cough stress test and 44 patients (46%) subjectively considered themselves "cured". Nine of 43 patients (21%) without urgency symptoms preoperatively developed de novo urgency; 24 of 35 patients (69%) with preoperative urgency complaints were free of urgency symptoms. At 2.4 years, the TVT-Secur appears to have a low adverse events profile but inferior results compared with traditional midurethral slings. Copyright © 2014 Elsevier Ireland Ltd.

Objective There are few studies comparing small and large craniotomies for the initial treatment of chronic subdural hematoma (CSDH) which had non-liquefied hematoma, multilayer intrahematomal loculations, or organization/calcification on computed tomography and magnetic resonance imaging. These procedures were compared to determine which would produce superior postoperative results. Methods Between 2001 and 2009, 317 consecutive patients were surgically treated for CSDH at our institution. Of these, 16 patients underwent a small craniotomy with partial membranectomy and 42 patients underwent a large craniotomy with extended membranectomy as the initial treatment. A retrospective review was performed to compare the postoperative outcomes of these two techniques, focusing on improvement of neurological status, complications, reoperation rate, and days of post-operative hospitalization. Results The mean ages were 69.4±12.1 and 55.6±9.3 years in the small and large craniotomy groups, respectively. The recurrence of hematomas requiring reoperation occurred in 50% and 10% of the small and large craniotomy patients, respectively (p<0.001). There were no significant differences in postoperative neurological status, complications, or days of hospital stay between these two groups. Conclusion Among the cases of CSDH initially requiring craniotomy, the large craniotomy with extended membranectomy technique reduced the reoperation rate, compared to that of the small craniotomy with partial membranectomy technique.

Prophylactic central neck dissection (pCND) for management of papillary thyroid carcinoma (PTC) is controversial. Compared to many malignancies, PTC has a high overall survival but local recurrence due to lymph node metastases continue to present management challenges. Unlike lateral cervical nodal metastasis metastasis, central neck nodal metastasis are unable to be reliably detected clinically or radiologically at pre-operative assessment. Residual disease (recurrent or persistent) typically requires re-operative surgery in the central compartment, which carries a heightened risk of significant morbidity. These nodal groups can be accessed during the index thyroidectomy for PTC. Thus, pCND offers potential to reduce the rates of recurrence and the need for re-operative surgery in the central neck. This benefit needs to be balanced with the potential morbidity risk from pCND itself at the index resection. This review will discuss the advantages and disadvantages of pCND with regard to long-term outcomes and potential morbidity. The rationale of pCND will be discussed, along with the indications for ipsilateral and contralateral pCND, the role of re-operative surgery for recurrence and the use of selective versus routine pCND. Strategies to select higher risk patients for pCND with the use of molecular markers will be addressed, along with a discussion of quality of life (QoL) research in PTC.

The reluctance to incise skin with electrocautery is partly attributable to concerns about excessive scarring and poor wound healing. However, recently no difference was reported in wound complications between the cold scalpel and electrocautery scalpel. We assessed the safety and efficacy of electrocautery skin incision in 22 scalp incisions, including 4 cases of reoperation. Electrocautery skin incisions were created using a sharp needle electrode. The generator unit was set on cutting mode, with power of 6 W and 330 kHz sinusoid waveform. Subcutaneous dissections also used the sharp needle electrode, set on coagulating mode, with power of 10 W and 1 MHz pulse-modulated waveform. Galea incisions used a standard blade tip, set on coagulating mode, with power of 20 W and 1 MHz pulse-modulated waveform. Skin incision with the sharp needle electrode caused no charring of the wound. Little bleeding or oozing were observed and skin clips were not necessary. No wound complication such as necrosis or infection occurred. Electrocautery skin incisions for re-operations were also performed safely without complications. Electrocautery skin incision is sufficiently safe procedure not only for first operation but also for re-operation. Electrocautery skin incision is efficacious, especially for extended operation times, because of little blood loss from the edges of skin incision and possible avoidance of skin edge necrosis or alopecia caused by skin clips.

The aim of this study was to determine the long-term clinical efficacy and complications of neuromodulation with a unilateral sacral foramen electrode in 36 patients with chronic voiding dysfunction. Following a positive effect of a percutaneous nerve evaluation test, patients underwent open surgery. A permanent electrode was implanted in 24 patients with urge incontinence, in 6 with urgency-frequency syndrome, and in 6 with nonobstructive urinary retention. After an average follow-up period of 37.8 months, 19 patients (52.8%) continue to benefit from the neuromodulation with a significant improvement of symptoms and urodynamic parameters. The median duration of the therapeutic effect for the total study population was longer than 60 months. No significant difference in the median duration of therapeutic effect with regard to sex, the type of voiding disorder, or the implant pulse generator was found. However, in patients with previous psychological disorders the median duration of therapeutic effect was only 12 months (P = 0.008). Complications were mild. In the group of patients in whom the therapeutic effect remains, 37 reoperations have had to be performed. We conclude that although reoperations were needed to overcome technical problems, patients can achieve lasting symptomatic improvement. Since technical changes in the equipment have reduced the number of complications, even better results can be expected in terms of the reoperation rate.

The efficacy of dexamethasone on reduction in the reoperation rate of chronic subdural hematoma – the DRESH study: straightforward study protocol for a randomized controlled trial

PubMed Central

2014-01-01

Background Chronic subdural hematoma (cSDH) is a common neurosurgical disease. It is often considered to be a rather benign entity. In spite of well established surgical procedures cSDH is complicated by a recurrence rate up to 30%. Since glucocorticoids have been used for treatment of cSDH in 1962 their role is still discussed controversially in lack of evident data. On the basis of the ascertained inflammation cycle in cSDH dexamethasone will be an ideal substance for a short lasting, concomitant treatment protocol. Objective: to test the efficacy of dexamethasone on reduction inthe reoperation rate of cSDH. Methods/Design The study is designed as a double-blind randomized placebo-controlled trial 820 patients who are operated for cSDH and from the age of 25 years are included after obtaining informed consent. They are randomized for administration of dexamethasone (16-16-12-12-8-4 mg/d) or placebo (maltodextrin) during the first 48 hours after surgery. The type I error is 5% and the type II error is 20%. The primary endpoint is the reoperation within 12 weeks postoperative. Discussion This study tests whether dexamethasone administered over 6 days is a safe and potent agent in relapse prevention for evacuated cSDH. Trial registration EudraCT 201100354442 PMID:24393328

The purpose of this study was to review surgical outcomes after elective placement of peritoneal dialysis (PD) catheters in children with end-stage renal disease. Children with PD catheters placed between February 2002 and July 2014 were retrospectively reviewed. Outcomes were catheter life, late (>30days post-op) complications (catheter malfunction, catheter malposition, infection), and re-operation rates. Comparison groups included laparoscopic versus open placement, age<2, and weight<10kg. Univariate and multivariate analysis were performed. One hundred sixteen patients had 173 catheters placed (122 open, 51 laparoscopic) with an average patient age of 9.7±6.3years. Mean catheter life was similar in the laparoscopic and open groups (581±539days versus 574±487days, p=0.938). The late complication rate was higher for open procedures (57% versus 37%, p=0.013). Children age<2 or weight<10kg had higher re-operation rates (64% versus 42%, p=0.014 and 73% versus 40%, p=0.001, respectively). Adjusted for age and weight, open technique remained a risk factor for late complications (OR 2.44, 95% CI 1.20-4.95) but not re-operation. Laparoscopic placement appears to reduce the rate of late complications in children who require PD dialysis catheters. Children <2years age or <10kg remain at risk for complications regardless of technique. Copyright © 2016 Elsevier Inc. All rights reserved.

A central challenge of integrated water management is the design and implementation of policies to allocate water to both humans and the environment in a sustainable manner. This study uses the results from a reach-scale water-planning model to quantify and compare the economic benefits of two water management policies: (1) a business as usual (Baseline) policy and (2) a proposed reservoir re-operation policy to provide environmental flows (EFs). Results show that the EF policy would increase water supply profit, slightly decrease recreational activities profit, and reduce costs from flood damage and environmental restoration compared to the Baseline policy. In addition to supporting ecological objectives, the proposed EF policy would increase the economic benefits of water management objectives.

The surgical treatment of cervical radiculopathy has centered around anterior cervical discectomy and fusion (ACDF). Alternatively, the posterior cervical laminoforaminotomy/microdiscectomy (PCF/PCM), which results in comparable outcomes and is more cost-effective, has been underutilized. Here, we compared the direct/indirect costs, reoperation rates, and outcome for ACDF and PCF vs. PCM using PubMed, Medline, and Embase databases. There were no significant differences between the re-operative rates of PCF/PCM (2% to 9.8%) versus ACDF (2% to 8%). Direct costs of ACDF were also significantly higher; the 1-year cost-utility analysis demonstrated that ACDF had $131,951/QALY while PCM had $79,856/QALY. PCF/PCM for radiculopathy are safe and more cost-effective vs. ACDF, and have similar clinical outcomes.

Glans size is an independent risk factor for urethroplasty complications after hypospadias repair.

We hypothesized small glans size could increase urethroplasty complications (UC) following hypospadias repair. To test this, we measured glans width at its widest point in consecutive patients with hypospadias, and following a protocol for surgical decision-making, we then assessed post-operative UC using pre-determined definitions. We now report analysis of glans size as a potential additional independent risk factor for UC after hypospadias repair. Consecutive prepubertal patients undergoing hypospadias repair (2009-2013) had maximum glans width measured using calipers (Fig. 1). There were no differences in surgical technique for urethroplasty or glansplasty in this series based on the measured size of the glans. Multivariate logistic regression analyzed UC (fistula, glans dehiscence, diverticulum, stricture and/or meatal stenosis) based on glans size while adjusting for patient age, meatus (distal or midshaft/proximal), type of repair (TIP, inlay, 2-stage), surgeon, and primary or reoperative repair. Glans size was analyzed as both a continuous and dichotomous variable, with small glans defined as <14 mm. Mean glans size was 15 mm (10-27 mm) in 490 boys (mean 1.5 years) undergoing 432 primary repairs (380d/19mid/33prox), and 58 reoperations (28d/7mid/23prox). Increasing age between 3 months and 10 years did not correlate with increasing glans size (R = 0.01, p = 0.18). 17% had small glans <14 mm. UC occurred in 61 (13%) primary TIP, 2-stage, and reoperative repairs, including 20/81 (25%) patients with small glans <14 mm, versus 41/409 (10%) in patients with glans width ≥14 mm (p = 0.0003). On multivariate analysis, small glans size (OR 3.5, 95% CI 1.8-6.8), reoperations (OR 3.0, 95% CI 1.4-6.5) and mid/proximal meatus (OR 3.1, 95% CI 1.6-6.2) were independent risk factors for UC. Surgeon, repair type, and patient age did not impact risk for UC. Analysis with glans size as a continuous variable demonstrated each 1 mm increase in size decreased odds of UC (OR 0.8, 95% CI 0.7-0.9). Our analysis of prospectively-collected data from a standardized management protocol in 490 consecutive boys undergoing hypospadias repair adds small glans size, defined as width <14 mm, to proximal meatal location and reoperation as an independent risk factor for UC. Best means to modify this factor remain to be determined. Our data suggest that others analyzing potential risks for hypospadias UC should similarly measure and report glans width.

2016-01-01

Parachute and hammock valves in children remain one of the most challenging congenital malformations to correct. We report our institutional experience with valve-preserving repair techniques and the early and late surgical outcomes in parachute and hammock valves in infants and children. From January 1990-June 2014, 20 infants and children with parachute (n = 12, median age = 2.5 years, range: 2 months-13 years) and hammock (n = 8, median age = 7 months, range: 1 month-14.9 years) valves underwent mitral valve (MV) repair. Children with parachute valves have predominant stenosis, whereas those with hammock valves often have predominant insufficiency. Intraoperative findings included fused and shortened chordae with single papillary muscles in children with parachute valves. MV repair was performed using annuloplasty, commissurotomy, leaflet incision toward the body of the papillary muscles, and split toward its base. Children with hammock valves have dysplastic and shortened chordae, absence of papillary muscles with fused and thickened commissures. MV repair consisted of carving off a suitably thick part of the left ventricular wall carrying the rudimentary chordae. The degree and extent of incision and commissurotomy is determined by the minimal age-related acceptable MV diameter to avoid mitral stenosis. During a median duration of follow-up of 9.6 years (range: 6.4-21.4 years), cumulative survival rate and freedom from reoperation in parachute valves were 43.7 ± 1.6% and 53.0 ± 1.8%, respectively. In hammock valves, during a median duration of follow-up of 6.7 years (range: 2.7-19.4 years), cumulative survival rate and freedom from reoperation was 72.9 ± 1.6% and 30.0 ± 1.7%, respectively. Age less than 1 year proved to be a high-risk factor for reoperation and mortality (P < 0.005). In conclusion, children with parachute and hammock valves, repeat MV repair may be necessary during the course of follow-up. Infants have a greater risk for reoperation and mortality.

The Florida sleeve (FS) procedure was developed as a simplified approach for repair of functional type I aortic insufficiency secondary to aortic root aneurysm. We evaluated postoperative aortic valve function, long-term survival, and freedom from reoperation in Marfan syndrome patients who underwent the FS procedure at our center. All Marfan syndrome patients undergoing FS procedure from May 2002 to December 2014 were included. Echocardiography assessment included left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), ejection fraction, and degree of aortic insufficiency (none = 0, minimal = 1, mild = 2, moderate = 3, severe = 4). Social Security Death Index and primary care physicians' report were used for long-term follow-up. Thirty-seven Marfan syndrome patients, 21 (56.8%) men and 16 (43%) women with mean age of 35.08 ± 13.45 years underwent FL repair at our center. There was no in-hospital or 30-day death or stroke. Two patients required reoperation due to bleeding. Patients' survival rate was 94% at 1 to 8 years. Freedom from reoperation was 100% at 8 years. Twenty-five patients had postoperative follow-up echocardiography at 1 week. Aortic insufficiency grade significantly decreased after the procedure (preoperative mean ± SD: 1.76 ± 1.2 versus 1-week postoperative mean ± SD: 0.48 ± 0.71, p < 0.001), and mean LVEDD decreased from 52.23 ± 5.29 mm to 47.53 ± 8.89 mm (p = 0.086). Changes in LVESD (35.33 ± 9.97 mm to 36.58 ± 9.82 mm, p = 0.58) and ejection fraction (57.65% ± 6.22% to 55% ± 10.83%, p = 0.31) were not significant. The FS procedure can be performed safely in Marfan syndrome patients with immediate improvement in aortic valve function. Long-term survival and freedom from reoperation rates are encouraging.

OBJECTIVE During the mini-open posterior corpectomy, percutaneous instrumentation without fusion is performed above and below the corpectomy level. In this study, the authors' goal was to compare the perioperative and long-term implant failure rates of patients who underwent nonfused percutaneous instrumentation with those of patients who underwent traditional open instrumented fusion. METHODS Adult patients who underwent posterior thoracic corpectomies with cage reconstruction between 2009 and 2014 were identified. Patients who underwent mini-open corpectomy had percutaneous instrumentation without fusion, and patients who underwent open corpectomy had instrumented fusion above and below the corpectomy site. The authors compared perioperative outcomes and rates of implant failure requiring reoperation between the open (fused) and mini-open (unfused) groups. RESULTS A total of 75 patients were identified, and 53 patients (32 open and 21 mini-open) were available for followup. The mean patient age was 52.8 years, and 56.6% of patients were male. There were no significant differences in baseline variables between the 2 groups. The overall perioperative complication rate was 15.1%, and there was no significant difference between the open and mini-open groups (18.8% vs 9.5%; p = 0.359). The mean hospital stay was 10.5 days. The open group required a significantly longer stay than the mini-open group (12.8 vs 7.1 days; p < 0.001). Overall implant failure rates requiring reoperation were 1.9% at 6 months, 9.1% at 1 year, and 14.7% at 2 years. There were no significant differences in reoperation rates between the open and mini-open groups at 6 months (3.1% vs 0.0%, p = 0.413), 1 year (10.7% vs 6.2%, p = 0.620), and 2 years (18.2% vs 8.3%, p = 0.438). The overall mean follow-up was 29.2 months. CONCLUSIONS These findings suggest that percutaneous instrumentation without fusion in mini-open transpedicular corpectomies offers similar implant failure and reoperation rates as open instrumented fusion as far out as 2 years of follow-up.

Purpose: To examine the influence of anatomic location in the upper extremity (UE) vs. lower extremity (LE) on the presentation and outcomes of adult soft tissue sarcomas (STS). Methods and Materials: From 2001 to 2008, 118 patients underwent limb-sparing surgery (LSS) and external beam radiotherapy (RT) with curative intent for nonrecurrent extremity STS. RT was delivered preoperatively in 96 and postoperatively in 22 patients. Lesions arose in the UE in 28 and in the LE in 90 patients. Patients with UE lesions had smaller tumors (4.5 vs. 9.0 cm, p < 0.01), were more likely to undergo a prior excisionmore » (43 vs. 22%, p = 0.03), to have close or positive margins after resection (71 vs. 49%, p = 0.04), and to undergo postoperative RT (32 vs. 14%, p = 0.04). Results: Five-year actuarial local recurrence-free and distant metastasis-free survival rates for the entire group were 85 and 74%, with no difference observed between the UE and LE cohorts. Five-year actuarial probability of wound reoperation rates were 4 vs. 29% (p < 0.01) in the UE and LE respectively. Thigh lesions accounted for 84% of the required wound reoperations. The distribution of tumors within the anterior, medial, and posterior thigh compartments was 51%, 26%, and 23%. Subset analysis by compartment showed no difference in the probability of wound reoperation between the anterior and medial/posterior compartments (29 vs. 30%, p = 0.68). Neurolysis was performed during resection in (15%, 5%, and 67%, p < 0.01) of tumors in the anterior, medial, and posterior compartments. Conclusions: Tumors in the UE and LE differ significantly with respect to size and management details. The anatomy of the UE poses technical impediments to an R0 resection. Thigh tumors are associated with higher wound reoperation rates. Tumor resection in the posterior thigh compartment is more likely to result in nerve injury. A better understanding of the inherent differences between tumors in various extremity sites will assist in individualizing treatment.« less

Open fractures are an important source of morbidity and are associated with delayed union, nonunion, and infection. Preventing infection through meticulous irrigation and debridement is an important goal in management, and different lavage fluids and irrigation techniques (e.g., high- or low-pressure lavage) have been described for this purpose. However, there are a limited number of randomized trials comparing irrigating solutions or irrigating technique. We compared the use of castile soap versus normal saline and high- versus low-pressure pulsatile lavage on the rates of reoperations and complications in patients with open fracture wounds. We conducted a multicenter, blinded, randomized 2 × 2 factorial pilot trial of 111 patients in whom an open fracture wound was treated with either castile soap solution or normal saline and either high- or low-pressure pulsatile lavage. The primary composite outcome of reoperation, measured at 12 months after initial operative procedure, included infection, wound healing problems, and nonunion. Planned reoperations were not included. Secondary outcomes included all infection, all wound healing problems, and nonunion as well as functional outcomes scores (EuroQol-5 dimensions and short form-12). Eighty-nine patients completed the 1-year follow-up. Among all patients, 13 (23%) in the castile soap group and 13 (24%) in the saline group had a primary outcome event (hazard ratio, 0.91, 95% confidence interval: 0.42-2.00, p = 0.52). Sixteen patients (28%) in the high-pressure group and 10 patients (19%) in the low-pressure group had a primary outcome event (hazard ratio 0.55, 95% confidence interval: 0.24-1.27, p = 0.17). Functional outcome scores showed no significant differences at any time point between groups. The fluid lavage of open wounds pilot randomized controlled trial demonstrated the possibility that the use of low pressure may decrease the reoperation rate for infection, wound healing problems, or nonunion. We have demonstrated the desirability and feasibility of a definitive trial examining the effects of alternative irrigation approaches.

Proximal femoral deformities and overcorrection of the acetabulum both can result in secondary femoroacetabular impingement and suboptimal clinical results after periacetabular osteotomy. The purpose of the present study was to determine the rate of complications, the need for reoperations, radiographic correction, and hip function among patients who underwent periacetabular osteotomy and combined femoral head-neck osteochondroplasty as compared with those who underwent periacetabular osteotomy alone. Patients who underwent periacetabular osteotomy with or without osteochondroplasty of the femoral head-neck junction were evaluated retrospectively after a minimum duration of follow-up of two years. We compared the two groups with regard to the modified Harris hip score, radiographic correction, complications, and reoperations. Forty patients (forty hips) who underwent periacetabular osteotomy in conjunction with a femoral head-neck osteochondroplasty were compared with forty-eight patients (forty-eight hips) who underwent an isolated periacetabular osteotomy. Patients were evaluated after a mean duration of follow-up of 3.4 years (range, 2.0 to 9.7 years). Preoperatively, the modified Harris hip score (and standard deviation) was 64.3 ± 13.2 for the study group and 63.2 ± 13.4 for the comparison group. At the time of the latest follow-up, the modified Harris hip score was not significantly different between the study group and the comparison group (p = 0.17). Patients demonstrated equivalent preoperative deformities and postoperative acetabular radiographic parameters. There was a significant decrease in the alpha angle and improvement in head-neck offset in the study group. There was one reoperation for secondary impingement and/or labral pathology in the study group, compared with four reoperations in the comparison group. There were no adhesions requiring surgery, femoral neck fractures, instances of osteonecrosis, or increases in heterotopic ossification in the study group. Femoral head-neck junction osteochondroplasty performed concurrently with a periacetabular osteotomy for the treatment of symptomatic acetabular dysplasia and associated femoral head-neck junction deformities is not associated with an increased complication rate. This combined procedure provides effective correction of associated femoral head-neck deformities and produces similar early functional outcomes when compared with isolated periacetabular osteotomy. Therapeutic Level III.

Results of the two-stage arterial switch operation in 49 patients with transposition of the great arteries, performed between January 1995 and September 2000, were reviewed retrospectively. Twenty-one patients had a ventricular septal defect. Anatomical correction was carried out 21.89 +/- 9.86 months after pulmonary artery banding, with or without a modified Blalock-Taussig shunt. Hospital mortality was 8% (4 patients). During follow-up of 30.12 +/- 14.38 months, there was 1 late death and 1 patient required reoperation for pseudoaneurysm of the ascending aorta. Actuarial survival and freedom from reoperation at 5 years were 90% and 97%, respectively. Late anatomic correction (> 6 months) after the preliminary procedure can be performed with an acceptable mortality and morbidity, but undue delay may lead to left ventricular dysfunction, arrhythmias, and new aortic valve regurgitation or subaortic stenosis.

We performed a review of a consecutive series of 487 patients undergoing the Ross operation to identify surgical techniques and clinical parameters that affect outcome. We performed a prospective review of consecutive patients from August 1986 through June 2002 and follow-up through August 2004. Patient age was 2 days to 62 years (median, 24 years), and 197 patients were less than 18 years of age. The Ross operation was performed as a scalloped subcoronary implant in 26 patients, an inclusion cylinder in 54 patients, root replacement in 392 patients, and root-Konno procedure in 15 patients. Clinical follow-up in 96% and echocardiographic evaluation in 77% were performed within 2 years of closure. Actuarial survival was 82% +/- 6% at 16 years, and hospital mortality was 3.9%. Freedom from autograft failure (autograft reoperation and valve-related death) was 74% +/- 5%. Male sex and primary diagnosis of aortic insufficiency (no prior aortic stenosis) were significantly associated with autograft failure by means of multivariate analysis. Freedom from autograft valve replacement was 80% +/- 5%. Freedom from endocarditis was 95% +/- 2%. One late thromboembolic episode occurred. Freedom from allograft reoperation or reintervention was 82% +/- 4%. Freedom from all valve-related events was 63% +/- 6%. In children survival was 84% +/- 8%, and freedom from autograft valve failure was 83% +/- 6%. The Ross operation provides excellent survival in adults and children willing to accept a risk of reoperation. Male sex and a primary diagnosis of aortic insufficiency had a negative effect on late results.

Anastomotic leak is one of the most feared complications of gastrointestinal surgery. Surgeons routinely perform a diverting loop ileostomy (DLI) to protect high-risk colo-rectal anastomoses. The NSQIP database was queried from 2012 to 2013 for patients undergoing open ileo-colic resection with and without a DLI. The primary outcome was the development of any anastomotic leak-including those managed operatively and non-operatively. Secondary outcomes included overall complication rate, return to the OR, readmission, and 30-day mortality. Four thousand one hundred fifty-nine patients underwent open ileo-colic resection during the study period. One hundred eighty-six (4.5 %) underwent a DLI. Factors associated with the addition of a DLI included emergency surgery, pre-operative sepsis, and IBD. There were 197 anastomotic leaks (4.7 %) with 100 patients requiring reoperation (2.4 %). DLI was associated with a decrease in anastomotic leaks requiring reoperation (DLI vs no DLI: 0 (0 %) vs 100 (2.5 %); p = 0.02) and with increased readmission (OR 1.93; 95 % CI 1.30-2.85; p = 0.001). DLI is rarely used for open ileo-colic resection. There were no serious leaks requiring reoperation in the DLI group. A DLI was associated with an almost two-fold increase in the odds of readmission. Surgeons must weigh the reduction in serious leak rate with postoperative morbidity when considering a DLI for open ileo-colic resection.

Thyroglossal duct cysts (TGDC) excisions was traditionally an inpatient procedure, but there has been a recent trend towards outpatient surgery. Our aim is to use the NSQIP-P to examine overall thirty-day outcomes for TGDC excision, and to determine whether they are affected by admission status and surgeon specialty. We assessed the demographics, preoperative risk factors, and negative outcomes of admitted and same-day surgery TGDC patients, and TGDC patients of surgeons with different training. Outcomes were thirty-day rates for readmissions, reoperations, unplanned reintubations, major complications, and minor complications. Of 377 TGDC patients, 81% had outpatient surgery and 19% had inpatient surgery. Pediatric otolaryngologists performed 64% of the operations, followed by pediatric surgeons, general otolaryngologists, and general and plastic surgeons (23%, 12%, and 2% respectively). There was a 3% reoperation rate, no major complications, and a 3% wound infection rate. In multivariate analysis, neither admission status nor surgeon specialty were associated with negative 30-day outcomes. Premature birth (OR 6.5, p = 0.008) and male sex (OR 16, p = 0.008) were the only significant predictors. Outpatient pediatric TGDC surgery appears to have similar readmission, complication, and reoperation rates as inpatient surgery. Thirty-day outcomes do not vary by the surgeon's training, although recurrence rates could not be evaluated with this database. This article is protected by copyright. All rights reserved.

Carcinoma gallbladder is associated with an overall 5-year survival rate reported less than 5% due to late diagnosis. Advent of ultrasound scanning may help in detecting gallbladder polyps and an early gallbladder cancer. Excellent 5-year survival (up to 100%) has been reported for Stage Ia disease and the survival has significantly improved for Stage Ib, II, and III if appropriate re-operation is carried out soon after the incidental detection of gallbladder cancer. Laparoscopic cholecystectomy (LC) is contraindicated in the presence of gallbladder cancer. It is recommended to excise all laparoscopic port sites, at the time of re-operation. Re-operation for Stage II gallbladder cancer is associated with a 90-100% 3-year survival rate. Patients with Stage III and IV tumors also benefit from an extended cholecystectomy. Patients with bulky primary tumors without lymph node metastases (T4N0) seem to have a better prognosis than those with distant lymph node metastases, and should be treated aggressively. It is advantageous to perform the appropriate extent of surgery for gallbladder cancer at the initial operation. Heightened awareness of the presence of cancer and the knowledge of appropriate management are important. For patients whose cancer is an incidental finding on pathologic review, re-resection is indicated for all disease except Stage Ia. Radiotherapy and chemotherapy have not been found effective as an adjuvant or palliative therapy in gallbladder cancer. Copyright 2006 Wiley-Liss, Inc.

Minimal access cardiac valve surgery is increasingly utilized. We report our 11-year experience with minimally invasive aortic valve surgery. From 07/96 to 12/06, 1005 patients underwent minimally invasive aortic valve surgery. Early and late outcomes were analyzed. Median patient age was 68 years (range: 24-95), 179 patients (18%) were 80 years or older, 130 patients (13%) had reoperative aortic valve surgery, 86 (8.4%) had aortic root replacement, 62 (6.1%) had concomitant ascending aortic replacement, and 26 (2.6%) had percutaneous coronary intervention on the day of surgery (hybrid procedure). Operative mortality was 1.9% (19/1005). The incidences of deep sternal wound infection, pneumonia and reoperation for bleeding were 0.5% (5/1005), 1.3% (13/1005) and 2.4% (25/1005), respectively. Median length of stay was 6 days and 733 patients (72%) were discharged home. Actuarial survival was 91% at 5 years and 88% at 10 years. In the subgroup of the elderly (> or =80 years), operative mortality was 1.7% (3/179), median length of stay was 8 days and 66 patients (37%) were discharged home. Actuarial survival at 5 years was 84%. There was a significant decreasing trend in cardiopulmonary bypass time, the incidence of bleeding, and operative mortality over time. Minimal access approaches in aortic valve surgery are safe and feasible with excellent outcomes. Aortic root replacement, ascending aortic replacement, and reoperative surgery can be performed with these approaches. These procedures are particularly well-tolerated in the elderly.

We report our experience in the elderly with aortic valve replacement using the Mitroflow A12 pericardial bioprosthesis. From January 1993 to January 2006, 491 patients over the age of 70 years received an aortic Mitroflow A12 bioprosthesis implantation. Concomitant procedures included coronary artery bypass grafting in 20% of patients. All patients had routine postoperative Echo-Doppler studies at discharge, one month and a mean of 11.1 months after surgery and annually thereafter. Twenty (4%) patients underwent a second aortic valve replacement due to bioprosthetic valve dysfunction (Group 2). Calcified stenosis was the most common finding at reoperation (98%). Median time to valve reoperation was 76 months. Of patients requiring reoperation, median age at first and second implantation was 73 (70-78) and 79 (76-83) years, respectively. For all patients, freedom from structural valve dysfunction (SVD) was 95+/-3% at 5 years and 55.8+/-2% at 10 years. Bioprosthetic valve deterioration was identified in 27 patients (Group 1). Median age of these patients at first operation and at diagnosis of deterioration by echo was 75 (70-84) and 77 (70-82) years, respectively. The median interval between operation and detection of bioprosthesis valve deterioration was 46 months. Among the total patient population, freedom from bioprosthetic deterioration was 85.7+/-2% at 5 years and 33.5+/-4% at 10 years. The Mitroflow A12 pericardial bioprosthesis provides less than optimal performance in elderly patients.

Resection line infiltration (RLI) after surgical treatment represents an unfavorable prognostic factor in advanced gastric cancer. We performed a retrospective analysis of 89 patients with resection line involvement who did not undergo reoperation. On behalf of the Italian Research Group for Gastric Cancer, we present the characteristics and outcome of 89 patients who were submitted to surgical resection for gastric cancer from 1988 to 2001 and did not undergo reoperation because of disease extension or associated pathologies. RLI was significantly higher in patients with T4 tumors and diffuse histological type. Anastomotic leakages were observed in 4.8% of infiltrated esophageal resection margins, whereas 1.9% of infiltrated duodenal resection lines showed duodenal fistulas. Five-year overall survival of patients with RLI was 29%. Prognosis was not affected by RLI in early forms (100% 5-year survival); however, 5-year survival in T2 and T3 stages was significantly lower with respect to the same stages without residual tumor. The influence of RLI on prognosis was confirmed in N0 as well as in N1 and N2 patients. RLI also was an independent prognostic at multivariate analysis (odds ratio = 1.5; 95% confidence interval, 1.08-2.08; P = 0.0144). RLI significantly affects long-term survival of advanced gastric cancer. The impact on prognosis is independent of lymph node involvement. Patients in good general condition for whom radical surgery is possible should be considered for reoperation.

Background: Adjustable suture used for years to improve the outcome of strabismus surgery. We surveyed outcome of our patients with strabismus who underwent adjustable suture. Materials and Methods: This retrospective study was performed at Ophthalmology Centre of Feiz Hospital in Isfahan on 95 participants that candidate for adjustable suture strabismus surgery. Patients were divided into three age groups: Under 10 years, 10-19 years, and 20 years and over. Outcome of adjustable suture surgery consequence of residual postoperative deviation was divided into four groups: Excellent, good, acceptable, and unacceptable. Results: Out of 95 patients studied, 51 (53.7%) were males and 44 (46.3%) were females. The mean of deviation angles were 53.8 ± 17.9 PD (Prism dioptres) in alt XT, 44.5 ± 12 PD in alt ET and 52 ± 13.5 PD in const ET, 47.1 ± 13.1PD in cons XT, respectively. There was no significant difference between the groups (P = 0.051). Results of surgery were in 38 patients (40%) excellent, in 31 patients (32.6%) good, in 19 patients (20%) acceptable, and in 7 patients (7.4%) unacceptable. Seven (7.4%) patients required reoperation. Conclusions: In the present study, the frequency of re-operation was much lower than other similar studies (7.4% vs. 30-50%). This suggests that the adjustable technique that used in our study can be associated with lower reoperation than other adjustable techniques used in the other similar studies. PMID:25250293

AIM To compare the outcome between patients with jejunoileal atresia (JIA) associated with cystic meconium peritonitis (CMP) and patients with isolated JIA (JIA without CMP). METHODS A retrospective study was conducted for all neonates with JIA operated in our institute from January 2005 to January 2016. Demographics including the gestation age, sex, birth weight, age at operation, the presence of associated syndrome was recorded. Clinical outcome including the type of operation performed, operative time, the need for reoperation and mortality were studied. The demographics and the outcome between the 2 groups were compared. RESULTS During the study period, 53 neonates had JIA underwent operation in our institute. Seventeen neonates (32%) were associated with CMP. There was no statistical difference on the demographics in the two groups. Patients with CMP had earlier operation than patients with isolated JIA (mean 1.4 d vs 3 d, P = 0.038). Primary anastomosis was performed in 16 patients (94%) with CMP and 30 patients (83%) with isolated JIA (P = 0.269). Patients with CMP had longer operation (mean 190 min vs 154 min, P = 0.004). There were no statistical difference the need for reoperation (3 vs 6, P = 0.606) and mortality (2 vs 1, P = 0.269) between the two groups. CONCLUSION Primary intestinal anastomosis can be performed in 94% of patients with JIA associated with CMP. Although patients with CMP had longer operative time, the mortality and reoperation rates were low and were comparable to patients with isolated JIA. PMID:28224094

The role of a defunctioning ileostomy in every anterior rectal resection with total mesorectal excision (TME) is still controversial. In this study, we aimed to review the current literature to determine the impact of ileostomy creation on postoperative outcomes in patients undergoing anterior rectal resection with TME. MEDLINE, Embase and Cochrane Library were searched for eligible studies. We analyzed data up to October 2017. Eligible studies had to compare patients with vs. without a defunctioning ileostomy in rectal cancer surgery and comprise data on anastomotic leakage in both groups. The primary outcome was anastomotic leakage. Secondary outcomes included the complication rate, mortality, reoperation rate, length of hospital stay and 30-day readmission. Initial search yielded 1,966 articles. Thorough evaluation resulted in 13 eligible articles which were analyzed. Leakage rate (RR = 0.43, 95% CI 0.28-0.67) and the number of reoperations (RR = 0.62, 95% CI 0.40-0.94) were significantly lower in the defunctioning stoma group. Morbidity was significantly higher in the stoma group (RR = 1.32, 95% CI 1.05-1.65). Analysis of mortality, length of hospital stay and readmission rate did not show any significant differences. A defunctioning ileostomy may decrease the anastomotic leakage rate, additionally significantly reducing the risk of reoperations but it may also increase the overall complication rate. The presence of the protective stoma has no effect on mortality, length of hospital stay and readmission rate.

The literature suggests lateral unicompartmental knee arthroplasties are associated with low revision rates. However, there are fewer reports describing techniques for lateral unicompartmental arthroplasty and whether technique influences ROM and function compared to reports for medial unicompartmental arthroplasty. We report our indications for lateral unicompartmental arthroplasty, how we perform this procedure, and the subsequent Knee Society scores, ROM, and revision and reoperation rates. From a retrospective review of electronic records from 2004 through 2008, we identified 93 patients who had 100 lateral unicompartmental arthroplasties. Indications were complete lateral bone-on-bone arthrosis with a correctible deformity and maintenance of the medial joint space on varus stress radiographs or isolated lateral disease by diagnostic arthroscopy. Average age was 68 years. Seventy percent of patients were women. At followup, we obtained Knee Society scores and ROM. Minimum followup was 24 months (average, 39 months; range, 24-81 months). At followup, Knee Society scores averaged 46 for pain, 94 for clinical, and 89 for function, and ROM averaged 124°. Three patients had reoperations: one an open reduction and internal fixation for fracture at 2 years postoperatively, one an arthroscopy for a medial meniscal tear, and one a revision for pain. Based on our observations, we believe complete cartilage loss laterally and correctible deformity with maintenance of the medial joint on varus stress radiographs are reasonable indications for lateral unicompartmental arthroplasty. We recommend a lateral parapatellar approach can be utilized. The early reoperation and revision rates were low.

Controversy persists regarding the perioperative management of clopidogrel among patients undergoing carotid endarterectomy (CEA). This study examined the effect of preoperative dual antiplatelet therapy (aspirin and clopidogrel) on in-hospital CEA outcomes. Patients undergoing CEA in the Vascular Quality Initiative were analyzed (2003-2014). Patients on clopidogrel and aspirin (dual therapy) were compared with patients taking aspirin alone preoperatively. Study outcomes included reoperation for bleeding and thrombotic complications defined as transient ischemic attack (TIA), stroke, or myocardial infarction. Secondary outcomes were in-hospital death and composite stroke/death. Univariate and multivariable analyses assessed differences in demographics and operative factors. Propensity score-matched cohorts were derived to control for subgroup heterogeneity. Of 28,683 CEAs, 21,624 patients (75%) were on aspirin and 7059 (25%) were on dual therapy. Patients on dual therapy were more likely to have multiple comorbidities, including coronary artery disease (P < .001), congestive heart failure (P < .001), and diabetes (P < .001). Patients on dual therapy were also more likely to have a drain placed (P < .001) and receive protamine during CEA (P < .001). Multivariable analysis showed that dual therapy was independently associated with increased reoperation for bleeding (odds ratio [OR], 1.71; 95% confidence interval [CI], 1.20-2.42; P = .003) but was protective against TIA or stroke (OR, 0.61; 95% CI, 0.43-0.87; P = .007), stroke (OR, 0.63; 95% CI, 0.41-0.97; P = .03), and stroke/death (OR, 0.66; 95% CI, 0.44-0.98; P = .04). Propensity score matching yielded two groups of 4548 patients and showed that patients on dual therapy were more likely to require reoperation for bleeding (1.3% vs 0.7%; P = .004) but less likely to suffer TIA or stroke (0.9% vs 1.6%; P = .002), stroke (0.6% vs 1.0%; P = .04), or stroke/death (0.7% vs 1.2%; P = .03). Within the propensity score-matched groups, patients on dual therapy had increased rates of reoperation for bleeding regardless of carotid symptom status. However, asymptomatic patients on dual therapy demonstrated reduced rates of TIA or stroke (0.6% vs 1.5%; P < .001), stroke (0.4% vs 0.9%; P = .01), and composite stroke/death (0.5% vs 1.0%; P = .02). Among propensity score-matched patients with symptomatic carotid disease, these differences were not statistically significant. Preoperative dual antiplatelet therapy was associated with a 40% risk reduction for neurologic events but also incurred a significant increased risk of reoperation for bleeding after CEA. Given its observed overall neurologic protective effect, continued dual antiplatelet therapy throughout the perioperative period is justified. Initiating dual therapy in all patients undergoing CEA may lead to decreased neurologic complication rates. Copyright © 2016 Society for Vascular Surgery. Published by Elsevier Inc.

We describe our use of a perforated titanium plate to perform a partial posterior fossa cranioplasty in the treatment of cerebellar ptosis and dural ectasia after posterior fossa decompression (PFD). Twelve patients who had undergone PFD underwent posterior fossa reconstruction using a titanium plate. Symptoms were related to either descent of the cerebellum into the decompression or to dural ectasia into the craniectomy defect. Twelve patients who had undergone large suboccipital craniectomies and who presented with persistent headaches and some with neurological symptoms related to syringomyelia, underwent reoperation with placement of a small titanium plate. Ten of 12 patients showed symptomatic improvement after reoperation. Placement of a titanium plate appears to be an effective method of treatment of cerebellar ptosis and dural ectasia after PFD for Chiari malformation. Copyright © 2014 Elsevier Inc.

Patient-related factors, aortic insufficiency, bicuspid aortic valve, aortic annulus dilatation, ascending aortic dilatation or aneurysm, and aortic valve endocarditis have been suggested as affecting the results of the Ross operation. The study aim was to assess the impact of prior aortic valve intervention on early and late results of a Ross operation. A total of 399 patients who underwent surgery between August 1986 and September 2000 were reviewed retrospectively. The patients were grouped as: no prior aortic valve intervention (NOAVI, n = 219); prior aortic valvuloplasty (AVP, n = 106); prior balloon aortic valvuloplasty (AVB, n = 40); and prior aortic valve replacement (AVR, n = 34). Details of operative and late mortality, autograft valve function, and homograft valve function were analyzed. Operative mortality was higher for AVB (10%; three deaths in neonates) than the other groups (from 2.3% to 5.9%) (p = 0.084). Freedom from autograft valve degeneration, defined as severe autograft valve insufficiency, non-endocarditis autograft valve reoperation or valve-related death, ranged from 93 +/- 3% for AVP to 76 +/- 8% for NOAVI at 10 years (p = 0.43). Freedom from homograft reoperation in the pulmonary position was 100% for AVB at six years, and 99 +/- 1% for AVP, 82 +/- 8% for NOAVI, and 70 +/- 13% for AVR at 10 years (p = 0.0026). There appears to be no significant difference between patients with and without prior aortic valve surgery, with respect to operative mortality or late autograft function. However, patients with prior AVR appear to have a significantly higher homograft reoperation rate after a Ross operation, the reasons for which are uncertain.

To establish a quality indicator that could be used in optimizing treatment for rhegmatogenous retinal detachment (RRD). The Danish National Patient Registry was used to identify surgery conducted in Denmark for RRD in the period 01 January 2001-31 December 2009. Cases were identified by diagnosis and surgical codes. A total of 6522 cases were operated for a primary RRD in the study period, and 22% (1434 patients) were reoperated for a redetachment. A Cox regression analysis showed that the risk of redetachment was equal to or less than detachment on the fellow eye 1 year after primary surgery with techniques not using silicone oil. The same was true 1.5 years after surgery for techniques using silicone oil. Based on this, we established a quality indicator defining failure as the need for operation for redetachment within 1 year from initial surgery when using techniques without oil and after 1.5 years for techniques using oil. Also the lack of oil removal within 1 year from initial surgery should be noted as an operational failure. We applied the quality indicators on the cohort of 6522 RRDs and found that in Denmark the need for redetachment surgery has decreased over time and also that high-volume departments have better outcome compared to smaller ones. The risk of reoperation for redetachment after initial surgery fulfils the criteria for a good quality indicator and can be used in RRD surgery. This indicator could aid in optimizing the management of RRD patients to minimize morbidity. © 2015 Acta Ophthalmologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

Laser vaporization of the prostate is one of the alternatives to transurethral resection of the prostate. Short-term studies report a comparable outcome after laser vaporization with the 532 nm 120-W GreenLight high-performance system (HPS) laser and the 980 nm 200 W high-intensity diode (diode) laser. In this study, we analyzed the intermediate-term results of both techniques. From January 2007 to January 2008, 112 consecutive patients with symptomatic benign prostate enlargement were nonrandomly assigned to treatment with the GreenLight laser or the diode laser. Perioperative parameters, postoperative functional outcome, complications, and the reoperation rate at 3 years were analyzed. Improvement of voiding symptoms (International Prostate Symptom Score, quality-of-life) and micturition parameters (maximum flow rate, postvoid residual volume) showed no significant difference between the HPS group and the diode group. A significantly higher reoperation rate was observed in the diode group in comparison to the HPS group (37.5% vs 8.9%, p=0.0003) due to obstructive necrotic tissue (16.1% vs 0%, p=0.0018), bladder neck stricture (16.1% vs 1.8%, p=0.008), and persisting or recurrent adenoma (5.4% vs 7.1%, p=0.70), respectively. Both lasers lead to comparable improvement of voiding parameters and micturition symptoms. Treatment with the 200 W diode laser led to a significantly higher reoperation rate, which might be attributed to a higher degree of coagulation necrosis. Thus, a careful clinical application of this diode laser type is warranted.

Although a high incidence of strut fracture of the Björk-Shiley convexo-concave (C-C) valve prosthesis has been reported, it is still controversial whether the prosthesis functioning normally should be replaced electively. To clarify our policy for this issue, we reviewed 28 patients who had undergone mitral valve replacement with a C-C valve prosthesis, and evaluated long-term results according to STS guidelines. The incidence of valve-related complications expressed as % patient-year were; structural deterioration 0.30, nonstructural dysfunction 0.30, thromboembolism 1.20. There were no thrombosed valves, anticoagulant-related hemorrhage or prosthetic valve endocarditis. The actuarial free rate after valve replacement with the C-C at 10 years, constructed by the Kaplan-Meier method, were compared with those with St. Jude Medical (SJM) valve prosthesis. (1) Actuarial survival: 77.9 vs 87.3 (NS), (2) Reoperation-free: 91.6 vs 98.0 (p < 0.05), (3) thromboembolism-free: 83.7 vs 83.9 (NS), (4) Event-free (hospital death+reoperation+valve-related complications: 71.2 vs 77.7 (NS). The long-term results with the C-C were compatible to those with a SJM valve prosthesis. However, if a strut fracture occurs, it is very difficult to save the patient's life. The hospital mortality of re-replacement of valve prosthesis during the last 10 years, at our institute, was 2.6%, which is almost equal to the cumulative risk of strut fracture of the C-C valve after 10 years (3.0%).(ABSTRACT TRUNCATED AT 250 WORDS)

Significant variation in colorectal surgery outcomes exists between different countries. Better understanding of the sources of variable outcomes using administrative data requires alignment of differing clinical coding systems. We aimed to map similar diagnoses and procedures across administrative coding systems used in different countries. Administrative data were collected in a central database as part of the Global Comparators (GC) Project. In order to unify these data, a systematic translation of diagnostic and procedural codes was undertaken. Codes for colorectal diagnoses, resections, operative complications and reoperative interventions were mapped across the respective national healthcare administrative coding systems. Discharge data from January 2006 to June 2011 for patients who had undergone colorectal surgical resections were analysed to generate risk-adjusted models for mortality, length of stay, readmissions and reoperations. In all, 52 544 case records were collated from 31 institutions in five countries. Mapping of all the coding systems was achieved so that diagnosis and procedures from the participant countries could be compared. Using the aligned coding systems to develop risk-adjusted models, the 30-day mortality rate for colorectal surgery was 3.95% (95% CI 0.86-7.54), the 30-day readmission rate was 11.05% (5.67-17.61), the 28-day reoperation rate was 6.13% (3.68-9.66) and the mean length of stay was 14 (7.65-46.76) days. The linkage of international hospital administrative data that we developed enabled comparison of documented surgical outcomes between countries.

The differences in clinical features, surgical outcome and long-term prognosis between men and women who undergo surgery for Type A aortic dissection are not well known. From January 2004 to December 2016, 303 patients, consisting of 147 women and 156 men, underwent surgery for acute Type A aortic dissection at our institution. We compared clinical outcomes between the 2 cohorts. Women were older than men (72.6 vs 63.0; P < 0.001). Operative mortality was similar between the groups (8.2% vs 8.9%; P = 0.80). The duration of intensive care unit stay (54 vs 64 h median; P = 0.03) and mechanical ventilator support (34 vs 43 h; P = 0.02) was significantly shorter in women. Multivariate logistic regression analysis revealed that preoperative cardiopulmonary resuscitation, cardiac tamponade, chronic obstructive pulmonary disease, haemodialysis and longer cardiopulmonary bypass time were independent risk factors for early death. Among the hospital survivors, the actuarial survival rate was 59.0% in women and 65.7% in men at 10 years (P = 0.81). During the follow-up period, there were 9 female and 27 male patients who underwent reoperation related to the aortic dissection. The rate of 10-year actuarial freedom from reoperation was 80.7% in women and 53.1% in men (log-rank P = 0.018). No differences were observed in both early and long-term mortality between women and men. Male patients had a significantly higher rate of reoperation. UMIN000029179.

To compare modular monolateral external fixators with single monolateral external fixators for the treatment of open and complex tibial shaft fractures, to determine the optimal construct for fracture union. A total of 223 tibial shaft fractures in 212 patients were treated with a monolateral external fixator from 2005 to 2011; 112 fractures were treated with a modular external fixator with ball-joints (group A), and 111 fractures were treated with a single external fixator without ball-joints (group B). The mean follow-up was 2.9 years. We retrospectively evaluated the operative time for fracture reduction with the external fixator, pain and range of motion of the knee and ankle joints, time to union, rate of malunion, reoperations and revisions of the external fixators, and complications. The time for fracture reduction was statistically higher in group B; the rate of union was statistically higher in group B; the rate of nonunion was statistically higher in group A; the mean time to union was statistically higher in group A; the rate of reoperations was statistically higher in group A; and the rate of revision of the external fixator was statistically higher in group A. Pain, range of motion of the knee and ankle joints, rates of delayed union, malunion and complications were similar. Although modular external fixators are associated with faster intraoperative fracture reduction with the external fixator, single external fixators are associated with significantly better rates of union and reoperations; the rates of delayed union, malunion and complications are similar.

Time to CUSUM: simplified reporting of outcomes in colorectal surgery.

Surgical audit has added value when outcomes can be compared and individual surgeons receive feedback. It is expected that surgeons compare their results with others in similar local practice, the published work, or peers from a craft group audit. Although feedback and comparison are worthy aims, for many surgeons the standards have not been agreed nor is there a craft group audit. The aim of this paper was to develop a reporting format for surgeons carrying out colorectal surgery in a regional hospital. The performance of 13 individual surgeons was analysed using a comprehensive colorectal audit with more than 600 cases. Feedback included caseload and type. Risk stratification of outcomes included; operation urgency, age and Physiological and Operative Severity Score for enUmeration of Mortality and Morbidity. Outcome measures were anastomotic leaks, end stoma rates, unplanned reoperations and mortality. Visual feedback included cumulative summation graphs for elective leaks, mortality and unplanned reoperations. A single A4 page of an individuals performance could be prepared that allowed comparison to the groups data overall. Alerts were set at 2-5% elective leaks, 4-7.5% mortality and 4-11% unplanned return to theatre. Cumulative summation graphs added to this allowed a visual guide to the key performance indicators. Surgeons need to determine how they will review their individual and collective results. These are equally important to the reported work. Detailed analysis of risk-stratified data should occur. Binary outcomes such as leak, mortality and unplanned reoperations may be followed by cumulative summation graphs. This provides a continually updated method of feedback, enabling immediate visual feedback of a surgeon's performance.

Prognosis in ovarian cancer is determined by completeness of cytoreduction and proper management by specialized oncological gynecologists. Incomplete initial debulking surgery in non-specialized Centers is, however, a reality and there is ongoing discussion about the best subsequent management of such patients. Patients with advanced ovarian cancer (International Federation of Gynecology and Obstetrics--FIGO FIGO stages IIIC-IV) who had biopsy by laparotomy or incomplete cytoreduction followed or not by chemotherapy further referred to our Institution between January 2002 and May 2014 were included. The two groups of incomplete cytoreduction [followed by upfront surgery or followed by chemotherapy and interval debulking surgery (IDS)] were compared and also compared against a cohort of 197 patients with similar characteristics who underwent upfront maximal surgery according to the standard at our Iinstitution during the same period. A total of 99 eligible patients were identified. Sixty-seven of them underwent biopsies by laparotomy and 32 underwent incomplete cytoreduction in other institutions. Twenty-eight patients underwent direct re-operation while 71 patients underwent neoadjuvant chemotherapy followed by IDS. The mean overall survival duration for patients with upfront reoperation was 31 months and 54 months for patients with neoadjuvant chemotherapy and IDS, considerably lower than the 72 months obtained for the group of 197 patients with maximal up-front complete cytoreduction at our Institution. Primary biopsy or incomplete cytoreduction reduces survival regardless of the subsequent approach. However, if incomplete cytoreduction has occurred, neoadjuvant chemotherapy followed by IDS is preferable to up-front reoperation.

The importance of supervision and of surgeons' level of experience in relation to patient outcome have been demonstrated in both hip fracture and arthroplasty surgery. The aim of this study was to describe the surgeons' experience level and the extent of supervision for: 1) fracture-related surgery in general; 2) the three most frequent primary operations and reoperations; and 3) primary operations during and outside regular working hours. A total of 9,767 surgical procedures were identified from the Danish Fracture Database (DFDB). Procedures were grouped based on the surgeons' level of experience, extent of supervision, type (primary, planned secondary or reoperation), classification (AO Müller), and whether they were performed during or outside regular hours. Interns and junior residents combined performed 46% of all procedures. A total of 90% of surgeries by interns were performed under supervision, whereas 32% of operations by junior residents were unsupervised. Supervision was absent in 14-16% and 22-33% of the three most frequent primary procedures and reoperations when performed by interns and junior residents, respectively. The proportion of unsupervised procedures by junior residents grew from 30% during to 40% (p < 0.001) outside regular hours. Interns and junior residents together performed almost half of all fracture-related surgery. The extent of supervision was generally high; however, a third of the primary procedures performed by junior residents were unsupervised. The extent of unsupervised surgery performed by junior residents was significantly higher outside regular hours. not relevant.

Observational analysis of retrospectively collected data. A retrospective study was performed in order to compare the surgical profile of risk factors and perioperative complications for laminectomy and laminectomy with fusion procedures in the treatment of SEA. Spinal epidural abscess (SEA) is a highly morbid condition typically presenting with back pain, fever, and neurologic deficits. Posterior fusion has been used to supplement traditional laminectomy of SEA to improve spinal stability. At present, the ideal surgical strategy - laminectomy with or without fusion - remains elusive. 30-day outcomes such as reoperation and readmission following laminectomy and laminectomy with fusion in patients with SEA were investigated utilizing the American College of Surgeons National Quality Improvement Program database. Demographics and clinical risk factors were collected, and propensity matching was performed to account for differences in risk profiles between the groups. 738 patients were studied (608 laminectomy alone, 130 fusion). The fusion population was in worse health. The fusion population experienced significantly greater rate of return to the operating room (odds ratio (OR) 1.892), with the difference primarily accounted for by cervical spine operations. Additionally, fusion patients had significantly greater rates of blood transfusion. Infection was the most common reason for reoperation in both populations. Both laminectomy and laminectomy with fusion effectively treat SEA, but addition of fusion is associated with significantly higher rates of transfusion and perioperative return to the operating room. In operative situations where either procedure is reasonable, surgeons should consider that fusion nearly doubles the odds of reoperation in the short-term, and weigh this risk against the benefit of added stability. 3.

Measured posterior annuloplasty for repair of non-ischemic mitral regurgitation. A single unit follow-up.

The aim of this report is to evaluate short- and long-term outcomes of annuloplasty method of our choice: measured posterior annuloplasty (MPA). MPA is a piece of a Duran ring cut to the length of free-edge of anterior mitral leaflet (AML) and anchored with multiple pledgeted U-sutures from trigone to trigone into the posterior annulus. From 1988 to 2000, 103 consecutive patients with non-ischemic mitral regurgitation were scheduled preoperatively to be repaired by MPA. Preoperative mitral valve regurgitation (MR) grade was 3.8+/-0.5 and decreased to 0.1+/-0.3 (P<0.0001) after repair. One patient was converted to insertion of mechanical prosthesis after grade 3 MR persisted after septal myectomy and MPA. Three patients needed instant revision of the repair one due to SAM and two due to stenosis. No patient had a stenosis or unacceptable (>1) MR after the procedure. There was one operative death (1.0%) and 3 hospital/30-day deaths (2.9%). Sixteen patients (16.3%) expired during the follow-up to 91 months (mean 57.4+/-19.5, median 60 months) none due to failure of MPA. There were no reoperations due to failure of MPA. Three patients had a reoperation, one for dehiscence of reconstruction after P2 resection and two patients due to progression of anterior leaflet degeneration and calcification with 4+ MR. New York Heart Association (NYHA) functional classification decreased from 2.3+/-0.8 to 1.4+/-0.6 (P<0.0001) and only one patient had an increase from II to III. Eighty-eight patients (96.7%) were in NYHA class I-II. Ten patients had an increase of MR from 0 to trace or 1 and one from 0 to 2. Two patients were diagnosed with mild stenosis without need of reoperation. MPA is a durable and stable alternative for repair of non-ischemic mitral regurgitation of different etiologies. The technique gives an objective measure of the length of the band and no patient is left with a significant MR or mitral valve stenosis (MS). First-time success rate is very high and instant repairs few and minor. Freedom of MPA related reoperations is 100%.

This study investigates factors associated with failure and reoperation after glenoid labrum repair. We studied a nonconcurrent cohort of consecutive patients undergoing arthroscopic superior labrum repair at a single institution by 2 fellowship-trained surgeons over a 10-year period. There were 348 patients included in this study with a mean age of 33.4 years (95% confidence interval [CI], 32.1 to 35.9) and a mean clinical follow-up of 12.3 months (95% CI, 10.9 to 13.8). The overall reoperation rate was 6.3%, with a revision labrum repair rate of 4.3%. Subsequent surgery and failure after arthroscopic labrum repair were significantly correlated with Workers' Compensation claims (odds ratio [OR], 4.6; P < .001; 95% CI, 1.8 to 11.7), the use of tobacco (OR, 12.0; P = .03; 95% CI, 1.2 to 114.9), and the use of absorbable poly-L/D-lactic acid (PLDLA) anchors (100% correlation, P < .001). The OR for having repeat surgery was 12.7 (95% CI, 4.9 to 32.9; P < .001) with poly-96L/4D-lactic acid (Mini-Revo; Linvatec, Largo, FL) and also increased with the use of poly-70L/30D-lactic acid (Bio-Fastak and Bio-Suturetak; Arthrex, Naples, FL) anchor material (P = .04) after removal of the patients exposed to poly-96L/4D-lactic acid anchors. The rates of repeat surgery with PLDLA anchors from Linvatec and PLDLA anchors from Arthrex were 24% and 4%, respectively. None of the patients treated with nonabsorbable suture anchors (polyether ether ketone or metallic) returned to the operating room (P < .001). After we controlled for associated factors in a multivariate analysis, the use of absorbable anchors, in particular poly-96L/4D-lactic acid anchors (OR, 14.7; P < .001), and having a work-related injury (OR, 8.1; P < .001) remained independent factors associated with both repeat surgery and revision superior labrum repair. Bioabsorbable PLDLA anchor material led to significantly more SLAP repair failures and reoperations compared with nonabsorbable suture anchors. Our recommendation is that glenoid labrum repairs be performed with nondegradable material and, specifically, that the use of anchors composed of PLDLA material should be avoided.

Background: Injury rates are high for collegiate football players. Few studies have evaluated the epidemiology of surgical procedures in National Collegiate Athletic Association (NCAA) Division I collegiate football players. Purpose: To determine the most common surgical procedures performed in collegiate football players over a 10-year period. Study Design: Descriptive epidemiological study. Methods: From the 2004-2005 season through the 2013-2014 season, all surgical procedures performed on athletes from a single NCAA Division I college football team during athletic participation were reviewed. Surgeries were categorized by anatomic location, and operative reports were used to obtain further surgical details. Data collected over this 10-season span included type of injury, primary procedures, reoperations, and cause of reoperation, all categorized by specific anatomic locations and position played. Results: From the 2004-2005 through the 2013-2014 seasons, 254 operations were performed on 207 players, averaging 25.4 surgical procedures per year. The majority of surgeries performed were orthopaedic procedures (92.1%, n = 234). However, there were multiple nonorthopaedic procedures (7.9%, n = 20). The most common procedure performed was arthroscopic shoulder labral repair (12.2%, n = 31). Partial meniscectomy (11.8%, n = 30), arthroscopic anterior cruciate ligament (ACL) reconstruction (9.4% n = 24), and arthroscopic hip labral repair (5.9% n = 15) were the other commonly performed procedures. There were a total of 29 reoperations performed; thus, 12.9% of primary procedures had a reoperation. The most common revision procedure was a revision open reduction internal fixation of stress fractures in the foot as a result of a symptomatic nonunion (33.33%, n = 4) and revision ACL reconstruction (12.5%, n = 3). By position, relative to the number of athletes at each position, linebackers (30.5%) and defensive linemen (29.1%) were the most likely to undergo surgery while kickers (6%) were the least likely. Conclusion: In NCAA Division I college football players, the most commonly performed surgeries conducted for injuries were orthopaedic in nature. Of these, arthroscopic shoulder labral repair was the most common, followed closely by partial meniscectomy. Nonorthopaedic procedures nonetheless accounted for a sizable portion of surgical volume. Familiarity with this injury and surgical spectrum is of utmost importance for the team physician treating these high-level contact athletes. PMID:27504464

Studies of long-term outcomes of discrete subaortic stenosis are rare. Therefore, we reviewed the long-term outcomes of fibromuscular resection in children with subaortic stenosis over 26 years from a single institution. We conducted a retrospective review of all children (n=72) who underwent resection of subaortic obstruction for discrete subaortic stenosis between 1989 and 2015. Median age at surgery was 5.0 years (2.7-7.6 years). There were no operative deaths but three late deaths (4.2%, 3/72). Overall Kaplan-Meier survival at 10 years was 93.0 ± 3.9% (95% CI: 79.6, 97.7). Peak instantaneous left ventricular outflow tract Doppler gradient decreased from 74.2±36.7mmHg (16.0-242.0mmHg) preoperatively to 12.8±7.4mmHg (2.6-36.0mmHg) postoperatively (p<0.001). Mean left ventricular outflow tract Doppler gradient decreased from 42.4±17.2mmHg (12.0-98.0) preoperatively to 7.5±2.7mmHg (1.4-19.3mmHg) postoperatively (p<0.001). However, over the mean follow-up period of 7.8±6.1 years (0.1-25.2 years), 29.0% (20/69) of patients had recurrence and 18.8% (13/69) required reoperation at median time of 4.8 years (3.1-9.1 years) after the initial repair. Freedom from reoperation at 10 years was 71.1±7.1% (95% CI: 54.6, 82.3). Risk factors for reoperation were age less than five years at initial repair (p=0.036) and extension of the membrane to the aortic valve (p=0.001). Aortic insufficiency was present in 54.2% (39/72) of patients preoperatively. Progression of aortic insufficiency occurred in 38.9% (28/72). Involvement of the aortic valve at initial repair was associated with need for subsequent aortic valve repair or replacement (p=0.01). Resection of subaortic obstruction is associated with low mortality and morbidity. Recurrence and reoperation rates are high and progression of aortic insufficiency following subaortic resection is common. Therefore, these patients warrant close follow-up into adult life.

Williams syndrome is an uncommon genetic disorder associated with supravalvular aortic stenosis (SVAS) in childhood. We reviewed outcomes of children with Williams syndrome who underwent repair of SVAS during a 30-year period at a single institution. Between 1982 and 2012, 28 patients with Williams syndrome were operated on for SVAS. Mean age at operation was 5.2 years (range, 3 months to 13 years), and mean weight at operation was 18.6 kg (range, 4.1 to 72.4 kg). Associated cardiac lesions in 11 patients (39.3%) were repaired at the time of the SVAS repair. The most common associated cardiac lesion was main pulmonary artery stenosis (8 of 28 [28%]). A 3-patch repair was performed in 10 patients, a Doty repair in 17, and a McGoon repair in 1 (3.6%). There were no early deaths. Follow-up was 96% complete (27 of 28). Overall mean follow-up was 11.2 years (range, 1 month to 27.3 years). Mean follow-up was 5 years (range, 1 month to 14.3 years) for the 3-patch repair patients and 14.7 years (range, 6 weeks to 27 years) for the Doty repair patients. Of the 17 Doty patients, there were 4 (24%) late deaths, occurring at 6 weeks, 3.5 years, 4 years, and 16 years after the initial operation. There were no late deaths in the 3-patch repair patients. Overall survival was 86% at 5, 10, and 15 years after repair. Survival was 82% at 5, 10 and 15 years for the Doty repair patients. Overall, 6 of 27 patients (22%) patients required late reoperation at a mean of 11.2 years (range, 3.6 to 23 years). No 3-patch repair patients required reoperation. Overall freedom from reoperation was 91% at 5 years and 73% at 10 and 15 years. Freedom from reoperation for the Doty repair patients was 93% at 5 years and 71% at 10 and 15 years. Surgical repair of SVAS in children Williams syndrome has excellent early results. However, significant late mortality and morbidity warrants close follow-up.

Unrecognized and inadequately repaired intraoperative durotomies may lead to cerebrospinal fluid leak, pseudomeningocele, and other complications. Few studies have investigated durotomy that is unrecognized intraoperatively and requires additional postoperative management (hereafter, late-presenting dural tear [LPDT]), although estimates of LPDT range from 0.6 to 8.3 per 1,000 spinal surgeries. These single-center studies are based on relatively small sample sizes for an event of this rarity, all with <10 patients experiencing LPDT. This investigation is the largest yet conducted on LPDT, and sought to identify incidence, risk factors for, and complications associated with LPDT. This observational cohort study employed the American College of Surgeons National Surgical Quality Improvement Program dataset (years 2012-2015). Patients who underwent spine surgery were identified based on presence of primary listed Current Procedural Terminology (CPT) codes corresponding to spinal fusion or isolated posterior decompression without fusion. The primary variable in this study was occurrence of LPDT, identified as reoperation or readmission with durotomy-specific CPT or International Classification of Diseases, Ninth Revision, Clinical Modification codes but without durotomy codes present for the index procedure. Descriptive statistics were generated. Bivariate and multivariate analyses were conducted using chi-square tests and multiple logistic regression, respectively, generating both risk factors for LPDT and independent association of LPDT with postoperative complications. Statistical significance was defined as p<.05. In total, 86,212 patients were analyzed. The overall rate of reoperation or readmission without reoperation for LPDT was 2.0 per 1,000 patients (n=174). Of LPDT patients, 97.7% required one or more unplanned reoperations (n=170), and 5.7% of patients (n=10) required two reoperations. On multivariate analysis, lumbar procedures (odds ratio [OR] 2.79, p<.0001, vs. cervical), procedures involving both cervical and lumbar levels (OR 3.78, p=.0338, vs. cervical only), procedures with decompression only (OR 1.72, p=.0017, vs. fusion and decompression), and operative duration ≥250 minutes (OR 1.70, p=.0058, vs. <250 minutes) were associated with increased likelihood of LPDT. Late-presenting dural tear was significantly associated with surgical site infection (SSI) (OR 2.54, p<.0001), wound disruption (OR 2.24, p<.0001), sepsis (OR 2.19, p<.0001), thromboembolism (OR 1.71, p<.0001), acute kidney injury (OR 1.59, p=.0281), pneumonia (OR 1.14, p=.0269), and urinary tract infection (UTI) (OR 1.08, p=.0057). Late-presenting dural tears occurred in 2.0 per 1,000 patients who underwent spine surgery. Patients who underwent lumbar procedures, decompression procedures, and procedures with operative duration ≥250 minutes were at increased risk for LPDT. Further, LPDT was independently associated with increased likelihood of SSI, sepsis, pneumonia, UTI, wound dehiscence, thromboembolism, and acute kidney injury. As LPDT is associated with markedly increased morbidity and potential liability risk, spine surgeons should be aware of best-practice management for LPDT and consider it a rare, but possible etiology for developing postoperative complications.

[Status of aortic valve reconstruction and Ross operation in aortic valve diseases].

PubMed

Sievers, Hans H

2002-08-01

At first glance the aortic valve is a relative simple valve mechanism connecting the left ventricle and the ascending aorta. Detailed analysis of the different components of the aortic valve including the leaflets and sinuses revealed a complex motion of each part leading to a perfect durable valve mechanism at rest and during exercise. Theoretically, the reconstruction or imitation of these structures in patients with aortic valve disease should lead to optimal results. Prerequisite is the exact knowledge of the important functional characteristics of the aortic valve. The dynamic behavior of the aortic root closely harmonizing with the leaflets not only warrants stress minimizing and valve durability, but also optimizes coronary flow, left ventricular function and aortic impedance. The newly discovered contractile capacity of the leaflets and the root components are important for tuning the dynamics. Isolated reconstruction of the aortic valve such as decalcification, commissurotomy, plication of ring or leaflets of a tricuspid aortic valve and cusp extension are seldom indicated in contrast to the reconstruction of the bicuspid insufficient valve. Proper indication and skilled techniques lead to excellent hemodynamic and clinical intermediate-term result up to 7 years after reconstruction. Latest follow-up revealed a mean aortic insufficiency of 0.7, maximal pressure gradient of 11.4 +/- 8.5 mm Hg with zero hospital or late mortality, reoperation or thromboembolic events in 22 patients. The reconstructive techniques for aortic root aneurysm and/or type A dissection according to David or Yacoub have become routine procedures in the last 10 years. The hemodynamic and clinical results are excellent with low reoperation rate and very low risk of thromboembolism. Generally, a maximal diameter of the root of 5 cm is indicative for performing the operation. In patients with Marfan's syndrome the reconstruction should be advanced even with smaller diameters especially if these are progressive and combined with aortic insufficiency. ROSS-OPERATION: The Ross-Operation includes the replacement of the diseased aortic valve with the pulmonary autograft and reconstruction of the right ventricular outflow tract using a homograft. The hemodynamic results are excellent regarding the autograft and also the clinical results with very low thromboembolic risk and acceptable reoperation rate. This method is especially indicated for active young patients, women, who desire children, athletes and patients in general, who like to avoid long-term anticoagulation. In some cases the homograft may develop a dysfunction predominantly a pulmonary stenosis requiring reoperation. In the author's series of 245 Ross-operations in 12 years the homograft had to be replaced in 4 cases without letality. Innovative, decellularized homografts with the potential to repopulate with autologeous cells show promising results after 1 year of clinical implantation without signs of antibody development. Probably these tissue-engineered modification may improve the homograft results. The reconstructive techniques of the aortic valve and the Ross-operation have a certain risk of reoperation that must be weighed against the advantages of very low hospital and late valve related death, excellent hemodynamics, very low risk of macro- and microembolism as well as bleeding, lack of long-term anticoagulation and unrestricted life-style.

The objective of the present study was to report our ongoing prospective cohort of autograft recipients with up to 21 years of follow-up. All consecutive patients (n = 161), operated between 1988 and 2010, were analysed. Mixed-effects models were used to assess changes in echocardiographic measurements (n = 1023) over time in both the autograft and the pulmonary allograft. The mean patient age was 20.9 years (range 0.05-52.7)-66.5% were male. Early mortality was 2.5% (n = 4), and eight additional patients died during a mean follow-up of 11.6 ± 5.7 years (range 0-21.5). Patient survival was 90% [95% confidence interval (CI), 78-95] up to 18 years. During the follow-up, 57 patients required a re-intervention related to the Ross operation. Freedom from autograft reoperation and allograft re-intervention was 51% (95% CI 38-63) and 82% (95% CI 71-89) after 18 years, respectively. No major changes were observed over time in autograft gradient, and allograft gradient and regurgitation. An initial increase of sinotubular junction and aortic anulus diameter was observed in the first 5 years after surgery. The only factor associated with an increased autograft reoperation rate was pre-operative pure aortic regurgitation (AR) (hazard ratio 1.88; 95% CI 1.04-3.39; P= 0.037). We observed good late survival in patients undergoing autograft procedure without reinforcement techniques. However, over half of the autografts failed prior to the end of the second decade. The reoperation rate and the results of echocardiographic measurements over time underline the importance of careful monitoring especially in the second decade after the initial autograft operation and in particular in patients with pre-operative AR.

Traditionally, healing after surgical endodontic retreatment (SER); i.e. apicectomy with or without a retrograde filling, is assessed in periapical radiographs (PR). Recently, the use of cone beam CT (CBCT) has increased within endodontics. Generally, CBCT detects more periapical lesions than PR, but basic research on the true nature of these lesions is missing. The objective was to assess the diagnostic validity of PR and CBCT for determining inflammation in SER cases that were re-operated (SER-R) due to unsuccessful healing, using histology of the periapical lesion as reference for inflammation. Records from 149 patients, receiving SER 2004-10, were screened. In total 108 patients (119 teeth) were recalled for clinical follow-up examination, PR and CBCT, of which 74 patients (83 teeth) participated. Three observers assessed PR and CBCT as "successful healing" or "unsuccessful healing" using Rud and Molven's criteria. SER-R was offered to all non-healed teeth with expected favourable prognosis for subsequent functional retention. During SER-R, biopsy was performed and histopathology verified whether or not inflammation was present. All re-operated cases were assessed non-healed in CBCT while 11 of these were assessed successfully healed in PR. Nineteen biopsies were examined. Histopathologic diagnosis revealed 42% (teeth = 8) without periapical inflammation, 16% (teeth = 3) with mild inflammation and 42% (teeth = 8) with moderate to intense inflammation. A correct diagnosis was obtained in 58% with CBCT (true positives) and 63% with PR (true positives+true negatives). Of the re-operated teeth, 42% had no periapical inflammatory lesion, and hence no benefit from SER-R. Not all lesions observed in CBCT represented periapical inflammatory lesions.

The coexistence of degenerative hip disease and spinal pathology is not uncommon with the number of surgical treatments performed for each condition increasing annually. The limited research available suggests spinal pathology portends less pain relief and worse outcomes after total hip arthroplasty (THA). We hypothesize that primary THA patients with preexisting lumbar spinal fusions (LSF) experience worse early postoperative outcomes. This study is a retrospective matched cohort study. Primary THA patients at 1 institution who had undergone prior LSF (spine arthrodesis-hip arthroplasty [SAHA]) were identified and matched to controls of primary THA without LSF. Early outcomes (<90 days) were compared. From 2012 to 2014, 35 SAHA patients were compared to 70 matched controls. Patients were similar in age, sex, American Society of Anesthesiologist score, body mass index, and Charlson Comorbidity Index. SAHA patients had higher rates of complications (31.4% vs 8.6%, P = .008), reoperation (14.3% vs 2.9%, P = .040), and general anesthesia (54.3% vs 5.7%, P = .0001). Bivariate analysis demonstrated SAHA to predict reoperation (odds ratio, 5.67; P = .045) and complications (odds ratio, 4.89; P = .005). With the numbers available, dislocations (0% vs 2.8%), infections (0% vs 8.6%), readmissions, postoperative walking distance, and disposition only trended to favor controls (P > .05). Comparing controls to SAHA patients with <3 or ≥3 levels fused, longer fusions had increased cumulative postoperative narcotic consumption (mean morphine equivalents, 44.3 vs 46.9 vs 169.4; P = .001). Patients with preexisting LSF experience worse early outcomes after primary THA including higher rates of complications and reoperation. Lower rates of neuraxial anesthesia and increased narcotic usage represent potential contributors. The complex interplay between the lumbar spine and hip warrants attention and further investigation.

2018-01-01

Total ankle arthroplasty (TAA) has historically resulted in inferior survivorship rates compared with total hip and knee arthroplasty, because of technical issues unique to ankle anatomy. In this study, a single-surgeon series of intra- and postoperative complications as well as resultant reoperations/revisions of the Tornier Salto Talaris, a fixed-bearing TAA prosthesis, were reviewed. Medical records from index procedure to latest follow-up of primary TAA were reviewed. Complications were categorized according to the Glazebrook classification; additional complications were documented. Concurrent procedures were recorded, and radiographs were analyzed for alignment, subsidence, and cyst formation. Time to complication onset and learning curve analyses were performed. One hundred four Salto Talaris TAA prostheses (96 patients), with an average follow-up of 46 months, were included. Thirty-five complications were identified in 32 ankles with a 34% complication rate, resulting in 11 reoperations (5 TAA revisions). Technical error (n = 12), wound healing (n = 9), and aseptic loosening (n = 4) were the most common complications, and there were no statistically significant differences in demographics or follow-up duration between cases with versus without complications. In both the cohorts with and without complications, there were moderate, negative correlations between radiographically observed keel osteopenia and lucency (ρ = -0.548, P = .00125, and ρ = -0.416, P = .000303, respectively); also, in the complication cohort, a weak, positive correlation between subsidence and lucency (ρ = 0.357, P = .0450) was found. Salto Talaris TAA survivorship and reoperation rates in our series were comparable with previous reports, using either the same or similar mobile-bearing prostheses; new information regarding complication, radiographic, and learning curve analyses was presented.

The goals following pulmonary valve replacement (PVR) are to optimize right ventricular hemodynamics and minimize the need for subsequent reoperations on the right ventricular outflow tract. We hypothesized PVR using a xenograft valved conduit would result in superior freedom from reoperation with sustained improvement in right ventricular chamber dimensions. Xenograft valved conduits placed in patients aged >16 years were reviewed from 2000 to 2010 to allow for a 5-year minimum follow-up. Preoperative, one-year, and the most recent echocardiograms quantified right ventricular chamber dimensions, corresponding Z scores, and prosthetic valve function. Magnetic resonance imaging (MRI) studies compared preoperative and follow-up right ventricular volumes. A total of 100 patients underwent PVR at 24 (19-34) years. Freedom from reintervention was 100% at 10 years. At most recent follow-up, only one patient had greater than mild pulmonary insufficiency. The one-year (17.3 ± 7.2 mm Hg; P < .01) and most recent follow-up (18.6 ± 9.8 mm Hg; P < .01) Doppler-derived right ventricular outflow tract gradients remained significantly lower than preoperative measurements (36.7 ± 27.0 mm Hg). Similarly, right ventricular basal diameter, basal longitudinal diameter, and the corresponding Z scores remained lower at one year and follow-up from preoperative measurements. From 34 MRI studies, the right ventricular end-diastolic indexed volume (161.7 ± 58.5 vs 102.9 ± 38.3; P < .01) and pulmonary regurgitant fraction (38.0% ± 15.9% vs 0.8% ± 3.3%; P < .01) were significantly lower at 7.1 ± 3.4 years compared to the preoperative levels. Use of a xenograft valved conduit for PVR results in excellent freedom from reoperation with sustained improvement in right ventricular dimensions at an intermediate-term follow-up.

Obesity has been associated with increased risk for postoperative CSF leak in patients with benign cranial nerve tumors. Other measures of postoperative morbidity associated with obesity have not been well characterized. Patients enrolled in the American College of Surgeons' National Surgical Quality Improvement Program (ACS-NSQIP) from 2007 to 2013 with a diagnosis code of a benign neoplasm of a cranial nerve were included. The primary outcome of postoperative morbidity was analyzed as well as secondary outcomes of readmission and reoperation. The main covariate of interest was body mass index (BMI). A total of 561 patients underwent surgery for a benign cranial nerve neoplasm between 2007 and 2013. Readmission data, available for 2012-2013(n=353), revealed hydrocephalus, facial nerve injury, or CSF leak requiring readmission or reoperation occurred in 0.85%, 1.42%, and 3.12%, respectively. Composite morbidity included wound complications, infection, respiratory insufficiency, transfusion requirement, stroke, venous thromboembolism, coma and cardiac arrest. On multivariable analysis patients with class I (BMI 30-34.9) and II (BMI 35-39.9) obesity showed trends towards increasing return to operating room, though not significant, but there was no trend for composite complications in class I and II obesity patients. However, class III obesity, BMI≥40, was associated with increased odds of composite morbidity (OR 4.40, 95% CI 1.24-15.88) and return to the operating room (OR 5.97, 95% CI 1.20-29.6) relative to patients with a normal BMI, 18.5-25. Obesity is an independent and important risk factor for composite morbidity in resection of benign cranial nerve neoplasms, and as such, merits discussion during preoperative counseling.

2017-01-01

Although direct-to-implant breast reconstruction is a more concise procedure than 2-stage expander/implant reconstruction, it is less frequently performed. Skeptics of direct-to-implant reconstruction cite risk of postoperative complications as a reason for its rejection. To determine whether these perceptions are valid, we evaluated our 13-year experience of acellular dermal matrix (ADM)-assisted, direct-to-implant breast reconstruction. We report complication and reoperation rates associated with this technique as well as predictors for these outcomes. This retrospective study included all patients who underwent immediate, ADM-assisted, direct-to-implant, breast reconstruction from December 2001 to May 2014 at 2 practices. Postoperative complications, defined as those occurring within the first 12 months after reconstructive surgery, were evaluated. Univariate/multivariate analyses were performed to determine the influence of patient-, breast-, and surgery-related characteristics on the development of complications. A total of 1584 breast reconstructions (721 bilateral, 142 unilateral) in 863 patients were performed; 35% were oncologic, and 65% were prophylactic reconstructions. Complication rate was 8.6% and included skin necrosis (5.9%), infection (3.0%), implant loss (2.9%), seroma (1.1%), and hematoma (0.9%). Reoperative rate in breasts with complications was 3.2%. Age 50 years or older, smoking, nonnipple-sparing mastectomy, and implant size of 600 mL or greater strongly predicted the development of complications (P < 0.001). Our cumulative 13-year experience demonstrates that immediate, ADM-assisted, direct-to-implant breast reconstruction is safe, effective, and reliable. Complication and reoperation rates are less than 10% and are comparable to those reported for 2-stage procedures in the published literature.

2018-06-01

Because of the health care initiative on quality improvement projects in academic medicine, this study explores the impact of different postgraduate years (PGYs) on unexpected re-operation rates. Using the National Surgical Quality Improvement Program 2005-2014, adult neurosurgical cases were divided into subspecialties: spine, open vascular, cranial, and functional. Comparison groups were cases involving junior residents (PGY 1-PGY 3), mid-level residents (PGY 4 + PGY 5), and senior residents (PGY 6 + PGY 7). Comorbidity disease burden was measured by frailty index. The primary outcome measure was 30-day unintended return to the operating room. Of the 9782 cases, re-operations were higher for those cases featuring a senior resident (5.6%) compared with mid-level resident (4.1%) and junior resident (3.8%) (P = 0.001). Although senior residents operated on patients with a statistically significantly higher neurologic disease burden, greater relative value units, longer operative times, and more 30-day postoperative adverse events, the level of resident training did not have an impact on revision surgery after multivariable logistical regression. The strongest predictors of return to the operating room included the frailty index (adjusted odds ratio [OR adj ] = 5.18, P < 0.001), functional subspecialty (OR adj  = 2.65, P < 0.001), and Wound Class 4 - dirty/infected wound (OR adj  = 2.33, P = 0.016). Resident participation in neurosurgical cases does not affect 30-day unplanned re-operation rates, which were affected by frailty index, functional subspecialty, and wound class.

The objectives of the present study were to find out the results and the factors affecting survival after primary knee arthroplasty with a cruciate-retaining prosthesis in severe valgus deformity. Forty-eight patients (52 knees) participated in the current follow-up study. All patients were followed at least 5 years or to first revision. Mean follow-up time was 9 years (range, 1 to 17 years).The Kaplan-Meier analysis revealed 79% (95% CI 68% to 91%) survival rate with revision for any reason and 81% (95% CI 70% to 93%) survival rate with revision for instability as an endpoint at 10 years. Preoperatively TFA was 23° (range, 15°-51°) in valgus and 7° (range, 21° valgus-4° varus) in valgus postoperatively. Of the 14 re-operated patients, eight were revised because of progressive postoperative medial collateral ligament instability. All re-operations were performed during the first 4 years of the follow-up. The mean TFA was 15.5° valgus postoperatively for those eight and the odds ratio for a revision was 2 (95% CI 1-3, p = 0.025) when compared to the rest of the study population. The residual valgus deformity increases the risk of re-operation and it should be avoided. If proper soft-tissue balance cannot be achieved or there is no functional medial collateral ligament present more constrained implants should be used. In selected cases where both bony correction and ligament balancing have properly been achieved the use of a cruciate-retaining type of prosthesis is justified. Copyright © 2010 Elsevier B.V.

The study aim was to determine the safety and benefits of minimally invasive mitral valve surgery without aortic cross-clamping for mitral valve surgery after previous cardiac surgery. Between January 2006 and August 2008, a total of 90 consecutive patients (38 females, 52 males; mean age 66 +/- 9 years) underwent minimally invasive mitral valve surgery after having undergone previous cardiac surgery. Of these patients, 80 (89%) underwent mitral valve replacement and 10 (11%) mitral valve repair utilizing a small (5 cm) right lateral thoracotomy along the 4th or 5th intercostal space under fibrillatory arrest (mean temperature 28 +/- 2 degrees C). The predicted mortality, calculated using the Society of Thoracic Surgeons (STS) algorithm, was compared to the observed mortality. The mean ejection fraction was 45 +/- 13%, mean NYHA class 3 +/- 1, while 66 patients (73%) had previous coronary artery bypass grafting and 37 (41%) had previous valve surgery. Twenty-six patients (29%) underwent non-elective surgery. Cardiopulmonary bypass was instituted through axillary (n = 19), femoral (n = 70) or direct use aortic (n = 1) cannulation. Operative mortality was 2% (2/90), lower than the STS-predicted mortality of 7%. Three patients (3%) developed acute renal failure postoperatively, one patient (1%) required new-onset hemodialysis, and one (1%) developed postoperative stroke. No patients developed postoperative myocardial infarction. The mean postoperative packed red blood cell transfusion requirement at 48 h was 2 +/- 3 units. Minimally invasive right thoracotomy without aortic cross-clamping is an excellent alternative to conventional redo-sternotomy for reoperative mitral valve surgery. The present study confirmed that this technique is safe and effective in reducing operative mortality in high-risk patients undergoing reoperative cardiac surgery.

High body mass index (BMI) is associated with increased rates of complications after total hip arthroplasty. Studies to date have evaluated risk mainly as a dichotomous variable according to BMI thresholds. The purpose of this paper was to characterize the risk of complications and implant survival according to BMI as a continuous variable. Using prospectively collected data from our institutional total joint registry, we analyzed 21,361 consecutive hips (17,774 patients) treated with primary total hip arthroplasty between 1985 and 2012 at a single institution. The average BMI at the time of surgery was 28.7 kg/m(2) (range, 15 to 69 kg/m(2)). Estimates of revision surgery and common complications associated with BMI were analyzed using the Kaplan-Meier method of assessing survivorship, with associations of outcomes assessed using a Cox model. Utilizing smoothing spline parameterization, we found that reoperation (p < 0.001) and implant revision or removal rates (p = 0.002) increased with increasing BMI. Increasing BMI was associated with increased rates of early hip dislocation (p = 0.02), wound infection, and, most strikingly, deep periprosthetic infection (a hazard ratio of 1.09 per unit of BMI >25 kg/m(2); p < 0.001). However, we found no association between increasing BMI and any revision for mechanical failure of the implant or between increasing BMI and revision for aseptic implant loosening. There was an inverse correlation between increasing BMI and risk of revision for bearing wear. The rates of reoperation, implant revision or removal, and common complications after total hip arthroplasty were strongly associated with BMI.

Aporowicz, Michał; Kaliszewski, Krzysztof; Bolanowski, Marek

2016-01-01

Introduction Surgical treatment of thyroid gland diseases is associated with the possibility of severe complications. The most dangerous of them is bleeding. Current studies focus on its risk factors, rather than reoperation-related consequences. Material and methods We analyzed 7805 thyroid operations performed from 1996 to 2014 in the Clinic of General, Gastroenterological and Endocrine Surgery of Wroclaw Medical University. Typical risk factors, symptoms and consequences of bleeding were analyzed. Results Among operated patients 88.2% were female and 11.8% male. Bleeding occurred in 84 (1.08%) patients. Sex (p = 0.006), preoperative thyroid pathology (p = 0.03), and type of operation (p < 0.001) are significant risk factors for bleeding, while retrosternal goiter and surgeon’s experience are not. Risk of bleeding is highest in the case of male sex, toxic goiter and total resection of the thyroid gland. Most reoperations took place within 6 h. In 88.8% of cases of this kind of complication the surgeon indicated the exact source of bleeding; most commonly it was the neck muscles, skin and subcutaneous tissue, or the thyroid stump. Three patients required a second reoperation, 24 suffered further complications, and 8 required transfer to the Intensive Care Unit (ICU). Cardiac arrest occurred in 3 patients and 2 suffered bilateral vocal cord palsy. Conclusions Bleeding after thyroid operations is a direct life threat that requires immediate intervention. As a result death may occur, half of patients suffer other complications and some require intensive care. The risk is highest in the case of male sex, toxic goiter and total resection of the thyroid gland. Each patient after thyroid surgery needs to be closely observed. An operating theatre and ICU should be available at all times. PMID:29593806

Factors determining the recurrence of chronic subdural hematomas (CSDHs) are not clear. Whether opening the so-called internal hematoma membrane is useful has not been investigated. To investigate whether splitting the inner hematoma membrane influences the recurrence rate in patients undergoing burr-hole craniotomy for CSDH. Fifty-two awake patients undergoing surgery for 57 CSDHs were prospectively randomized to either partial opening of the inner hematoma membrane (group A) or not (group B) after enlarged burr-hole craniotomy and hematoma evacuation. Drainage was left in situ for several days postoperatively. Groups were comparable with regard to demographic, clinical, and imaging variables. Outcome was assessed after 3-6 weeks for the combined outcome variable of reoperation or residual hematoma of one third or more of the original hematoma thickness. Fourteen patients underwent reoperation for clinical deterioration or residual hematoma during follow-up (n = 6 in group A, 21%; n = 8 in group B, 28 %) (P = 0.537). Residual hematoma of ≥ one third not requiring surgery was present in 7 patients in group A (25%) and 10 patients in group B (36%) (P = 0.383). The overall cumulative failure rate (reoperation or hematoma thickness ≥ one third) was 13/28 (46%) in group A and 18/28 in group B (P = 0.178; relative risk, 0.722 [95% confidence interval, 0.445-1.172]; absolute risk reduction -16% [95% confidence interval, -38% to 8%]). Opening the internal hematoma membrane does not alter the rate of patients requiring revision surgery and the number of patients showing a marked residual hematoma 6 weeks after evacuation of a CSDH.

To evaluate the early clinical results of distal femur fractures treated with carbon fiber reinforced - polyetheretherketone (CFR-PEEK) plates compared to stainless steel (SS) lateral locking plates. Retrospective comparative cohort study SETTING:: ACS Level I trauma center. Twenty-two patients (11 SS, 11 CFR-PEEK) with closed distal femur fractures treated by a single surgeon over a 6-year period. Nonunion, hardware failure, reoperation, time to full weight bearing, and time ` union were assessed. The CFR-PEEK cohort was on average older (71 vs. 57 years, p=0.03) and more likely to have diabetes (p=0.02). Nonunion was diagnosed in 4/11 (36%) patients in the SS group and 1/11 (9%) patients in the CFR-PEEK group (p=0.12). Hardware failure occurred in two SS patients (18%) compared to none in the CFR-PEEK group (p=0.14). Time to full weight bearing was similar between groups occurring at 9.9 weeks and 12.4 weeks in the CFR-PEEK and SS groups, respectively (p=0.23). Time to radiographic union averaged 12.4 weeks in the SS group and 18.7 weeks in the CFR-PEEK group (p=0.26). There were 4 reoperations in the SS group and one in the CFR-PEEK group (p=0.12). CFR-PEEK plates show encouraging short-term results in the treatment of distal femur fractures with a comparable nonunion, reoperation, and hardware failure rates to those treated with SS plates. This data suggests CFR-PEEK plates may be a viable alternative to SS plates in fixation of these fractures. Level III.

Resective epilepsy surgery has been shown to have up to 70-80% success rates in patients with intractable seizure disorder. Around 20-30% of patients with Engel Classification III and IV will require reevaluation for further surgery. Common reasons for first surgery failures include incomplete resection of seizure focus, incorrect identification of seizure focus and recurrence of tumor. Clinical chart review of seventeen patients from a single adult comprehensive epilepsy program who underwent reoperation from 2007 to 2014 was performed. High resolution Brain MRI, FDG-PET, Neuropsychometric testing were completed in all cases in both the original surgery and the second procedure. Postoperative outcomes were confirmed by prospective telephone follow up and verified by review of the patient's electronic medical records. Outcomes were classified according to the modified Engel classification system: Engel classes I and II are considered good outcomes. A total of seventeen patients (involving 10 females) were included in the study. The average age of patients at second surgery was 42 (range 23-64 years). Reasons for reoperation included: incomplete first resection (n=13) and recurrence of tumor (n=4). Median time between the first and second surgery was 60 months. After the second surgery, ten of the seventeen patients (58.8%) achieved seizure freedom (Engel Class I), in agreement with other published reports. Of the ten patients who were Engel Class I, seven required extension of the previous resection margins, while three had surgery for recurrence of previously partially resected tumor. We conclude that since the risk of complications from reoperation is low and the outcome, for some, is excellent, consideration of repeat surgery is justified. Copyright © 2017 Elsevier B.V.

Anterior cervical spine decompression and fusion are common neurosurgical operations. Reoperation of the anterior cervical spine is associated with increased morbidity. The authors describe a novel subcricoid approach to protect the recurrent laryngeal nerve in a cuff of tissue while facilitating surgical access to the anterior cervical spine. Single institution, consecutive case review of 48 patients undergoing reoperation in the anterior cervical region including the level of C5 and below. Univariable and multivariable regression analysis was used to determine predictors of postoperative morbidity. No intraoperative complications were reported. Estimated blood loss for the approach was 13.6 ± 3.1 mL. Nine of 48 patients developed immediate postoperative complications, including vocal cord paresis (10.4%), moderate-to-severe dysphagia (10.4%), and neck edema requiring intubation (2.1%). No postoperative hematomas or death occurred. All complications occurred with 4 or more levels of exposure (1-3 disc levels, 0%, vs. ≥ 4 disc levels, 31%). Extension of the exposure to the upper thoracic spine was associated with odds for postoperative complications (adjusted odds ratio, 6.50; 95% confidence interval, 1.14-37.03) and prolonged hospital stay (adjusted increase 4.23 days, P < 0.01). The tunneled subcricoid approach is a relatively safe corridor to reapproach the anterior cervical spine at the level of C5 and below. However, caution must be exercised when using this approach to expose 4 or more disc levels and with extension of the exposure to the upper thoracic spine. Future comparative studies are needed to establish patient selection criteria in determining the use of this technique compared with classic approaches. Copyright © 2016 Elsevier Inc.

The objective of this analysis is to evaluate the necessity of large clinical trials using FLOW trial data. The FLOW pilot study and definitive trial were factorial trials evaluating the effect of different irrigation solutions and pressures on re-operation. To explore treatment effects over time, we analyzed data from the pilot and definitive trial in increments of 250 patients until the final sample size of 2447 patients was reached. At each increment we calculated the relative risk (RR) and associated 95% confidence interval (CI) for the treatment effect, and compared the results that would have been reported at the smaller enrolments with those seen in the final, adequately powered study. The pilot study analysis of 89 patients and initial incremental enrolments in the FLOW definitive trial favored low pressure compared to high pressure (RR: 1.50, 95% CI: 0.75-3.04; RR: 1.39, 95% CI: 0.60-3.23, respectively), which is in contradiction to the final enrolment, which found no difference between high and low pressure (RR: 1.04, 95% CI: 0.81-1.33). In the soap versus saline comparison, the FLOW pilot study suggested that re-operation rate was similar in both the soap and saline groups (RR: 0.98, 95% CI: 0.50-1.92), whereas the FLOW definitive trial found that the re-operation rate was higher in the soap treatment arm (RR: 1.28, 95% CI: 1.04-1.57). Our findings suggest that studies with smaller sample sizes would have led to erroneous conclusions in the management of open fracture wounds.

Objective Acute mitral stenosis (MS) following mitral valve (MV) repair is a rare but severe complication. We hypothesize that intraoperative echocardiography can be utilized to diagnose iatrogenic MS immediately after MV repair. Methods The medical records of 552 consecutive patients undergoing MV repair at a single institution were reviewed. Post-cardiopulmonary bypass peak and mean transmitral pressure gradients (TMPG), and pressure half time (PHT) were obtained from intraoperative transesophageal echocardiographic (TEE) examinations in each patient. Results Nine patients (9/552 = 1.6%) received a reoperation for primary MS, prior to hospital discharge. Interestingly, all of these patients already showed intraoperative post-CPB mean and peak TMPGs that were significantly higher compared to values for those who did not: 10.7±4.8 mmHg vs 2.9±1.6 mmHg; p<0.0001 and 22.9±7.9 mmHg vs 7.6±3.7 mmHg; p<0.0001, respectively. However, PHT varied considerably (87±37 ms; range: 20–439 ms) within the entire population, and only weakly predicted the requirement for reoperation (113±56 vs. 87±37 ms, p = 0.034). Receiver operating characteristic curves showed strong discriminating ability for mean gradients (AUC = 0.993) and peak gradients (area under the curve, AUC = 0.996), but poor performance for PHT (AUC = 0.640). A value of ≥7 mmHg for mean, and ≥17 mmHg for peak TMPG, best separated patients who required reoperation for MS from those who did not. Conclusions Intraoperative TEE diagnosis of a peak TMPG ≥17 mmHg or mean TMPG ≥7 mmHg immediately following CPB are suggestive of clinically relevant MS after MV repair. PMID:22087230

Ulcerative colitis (UC) patients requiring colectomy often have a staged ileal pouch anal anastomosis (IPAA). There are no prospective data comparing timing of pouch creation. We aimed to compare 30-day adverse event rates for pouch creation at the time of colectomy (PTC) with delayed pouch creation (DPC). Using prospectively collected data from 2011-2015 through the National Surgical Quality Improvement Program, we conducted a cohort study including subjects aged ≥18 years with a postoperative diagnosis of UC. We assessed 30-day postoperative rates of unplanned readmissions, reoperations, and major and minor adverse events (AEs), comparing the stage of the surgery where the pouch creation took place. Using a modified Poisson regression model, we estimated risk ratios (RRs) with 95% confidence intervals (CIs) adjusting for age, sex, race, body mass index, smoking status, diabetes, albumin, and comorbidities. Of 2390 IPAA procedures, 1571 were PTC and 819 were DPC. In the PTC group, 51% were on chronic immunosuppression preoperatively, compared with 15% in the DPC group (P < 0.01). After controlling for confounders, patients who had DPC were significantly less likely to have unplanned reoperations (RR, 0.42; 95% CI, 0.24-0.75), major AEs (RR, 0.72; 95% CI, 0.52-0.99), and minor AEs (RR, 0.48; 95% CI, 0.32-0.73) than PTC. Patients undergoing delayed pouch creation were at lower risk for unplanned reoperations and major and minor adverse events compared with patients undergoing pouch creation at the time of colectomy. 10.1093/ibd/izy082_video1izy082.video15776112442001.

The right anterolateral thoracotomy is an alternative technique for surgical approach of mitral valve. In these cases, femoral-femoral bypass still has been used, rising occurrence of complications related to femoral cannulation. Describe the technique and results of mitral valve treatment by right anterolateral thoracotomy using aortic cannulation for cardiac pulmonary bypass (CPB). From 1983 e 2008, 100 consecutive female patients, with average age 35 ±13 years, 96 (96%) underwent mitral valve surgical treatment in the Heart Institute of São Paulo. A right anterolateral thoracotomy approach associated with aortic cannulation was used for CPB. Eighty (80%) patients had rheumatic disease and 84 (84%) patients presented functional class III or IV. Were performed 45 (45%) comissurotomies, 38 (38%) valve repairs, 7(7%) mitral valve replacements, seven (7%) recomissurotomies and three (3%) prosthesis replacement. Sparing surgery was performed in 90 (90%) patients. The average CPB and clamp time were 57 ± 27 min e 39 ± 19 min, respectively. There were no in-hospital death, reoperation due to bleeding and convertion to sternotomy. Introperative complications were related to heart harvest (5%), especially in reoperations (3%). The most important complications in postoperative period were related to pulmonary system (11%), followed by atrial fibrilation (10%) but without major systemic repercussions. The mean inhospital length of stay was 8 ± 3 days. Follow-up was 6.038 patients/month. Actuarial survival was 98.0 ± 1.9% and freedom from reoperation was 81.4 ± 7.8% in 180 months. The right anterolateral thoracotomy associated with aortic cannulation in mitral valve surgery is a simple technique, reproducible and safety.

Abstract Background: Laparoscopic Nissen fundoplication (LNF) has been the gold standard for the surgical management of Gastro-esophageal reflux disease (GERD). Laparoscopic anterior 180° fundoplication (180° LAF) is reported to reduce the incidence of postoperative complications while obtaining similar control of reflux. The present meta-analysis was conducted to confirm the value of the 2 techniques. Methods: PubMed, Medline, Embase, Cochrane Library, Springerlink, and China National Knowledge Infrastructure Platform databases were searched for randomized controlled trials (RCTs) comparing LNF and 180° LAF. Data regarding the benefits and adverse results of 2 techniques were extracted and compared using a meta-analysis. Results: Six eligible RCTs comparing LNF (n = 266) and 180° LAF (n = 265) were identified. There were no significant differences between LNF and 180° LAF with regard to operating time, perioperative complications, length of hospital stay, patient satisfaction, willingness to undergo surgery again, quality of life, postoperative heartburn, proton pump inhibitor (PPI) use, postoperative DeMeester scores, postoperative lower esophageal sphincter (LES) pressure, postoperative gas-bloating, unable to belch, diarrhea, or overall reoperation. LNF was associated with a higher prevalence of postoperative dysphagia compared with 180° LAF, while 180° LAF was followed by more reoperation for recurrent reflux symptoms. Conclusion: LNF and 180° LAF are equally effective in controlling reflux symptoms and obtain a comparable prevalence of patient satisfaction. 180° LAF can reduce the incidence of postoperative dysphagia while this is offset by a higher risk of reoperation for recurrent symptoms. The risk of recurrent symptoms should need to be balanced against the risk of dysphagia when surgeons choose surgical procedures for each individual with GERD. PMID:28906412

The study objective was to evaluate patients with Marfan syndrome and mitral valve regurgitation undergoing valve repair or replacement and to compare them with patients undergoing repair for myxomatous mitral valve disease. We reviewed the medical records of consecutive patients with Marfan syndrome treated surgically between March 17, 1960, and September 12, 2011, for mitral regurgitation and performed a subanalysis of those with repairs compared with case-matched patients with myxomatous mitral valve disease who had repairs (March 14, 1995, to July 5, 2013). Of 61 consecutive patients, 40 underwent mitral repair and 21 underwent mitral replacement (mean [standard deviation] age, 40 [18] vs 31 [19] years; P = .09). Concomitant aortic surgery was performed to a similar extent (repair, 45% [18/40] vs replacement, 43% [9/21]; P = .87). Ten-year survival was significantly better in patients with Marfan syndrome with mitral repair than in those with replacement (80% vs 41%; P = .01). Mitral reintervention did not differ between mitral repair and replacement (cumulative risk of reoperation, 27% vs 15%; P = .64). In the matched cohort, 10-year survival after repair was similar for patients with Marfan syndrome and myxomatous mitral disease (84% vs 78%; P = .63), as was cumulative risk of reoperation (17% vs 12%; P = .61). Patients with Marfan syndrome and mitral regurgitation have better survival with repair than with replacement. Survival and risk of reoperation for patients with Marfan syndrome were similar to those for patients with myxomatous mitral disease. These results support the use of mitral valve repair in patients with Marfan syndrome and moderate or more mitral regurgitation, including those having composite replacement of the aortic root.

Centrifugation (Cf) is a common method of fat processing but may be time consuming, especially when processing large volumes. To determine the effects on fat grafting time, volume efficiency, reoperations, and complication rates of Cf vs an autologous fat processing system (Rv) that incorporates fat harvesting and processing in a single unit. We performed a retrospective cohort study of consecutive patients who underwent autologous fat grafting during reconstructive breast surgery with Rv or Cf. Endpoints measured were volume of fat harvested (lipoaspirate) and volume injected after processing, time to complete processing, reoperations, and complications. A budget impact model was used to estimate cost of Rv vs Cf. Ninety-eight patients underwent fat grafting with Rv, and 96 patients received Cf. Mean volumes of lipoaspirate (506.0 vs 126.1 mL) and fat injected (177.3 vs 79.2 mL) were significantly higher (P < .0001) in the Rv vs Cf group, respectively. Mean time to complete fat grafting was significantly shorter in the Rv vs Cf group (34.6 vs 90.1 minutes, respectively; P < .0001). Proportions of patients with nodule and cyst formation and/or who received reoperations were significantly less in the Rv vs Cf group. Based on these outcomes and an assumed per minute operating room cost, an average per patient cost savings of $2,870.08 was estimated with Rv vs Cf. Compared to Cf, the Rv fat processing system allowed for a larger volume of fat to be processed for injection and decreased operative time in these patients, potentially translating to cost savings.

The impending burden of revision shoulder arthroplasty has increased interest in outcomes of revision procedures. Painful glenoid arthrosis following hemiarthroplasty is a common cause of reoperation, and conversion to anatomic total shoulder arthroplasty is one option. We identified patients who underwent revision of painful hemiarthroplasty to total shoulder arthroplasty over a 15-year period in a single tertiary-care health system. Presurgical and operative data were analyzed for 28 patients who met the inclusion and exclusion criteria. Patients were contacted at a minimum of 2 years' follow-up after revision surgery for functional outcome scores, reoperations, and implant survival. The 2- and 5-year implant survival rates were 93% and 86%, respectively. Functional outcomes were obtained from 21 patients with surviving implants. The mean American Shoulder and Elbow Surgeons score, visual analog scale score for pain, and Single Assessment Numerical Evaluation score were 78 ± 20, 2.3 ± 2.6, and 71 ± 24, respectively. The mean Short Form 12 mental and physical scores were 49 ± 10 and 43 ± 9, respectively. Of the patients, 17 (81%) were either satisfied or very satisfied with their outcome. Complications were seen in 10 patients (36%), and 6 patients (21%) required reoperation. Anatomic total shoulder arthroplasty following hemiarthroplasty can achieve successful outcomes and implant survival rates. Given our poor understanding of reverse shoulder arthroplasty longevity, this procedure should remain an option for patients with glenoid arthrosis and an intact rotator cuff.

To identify modifiable factors related to post-operative dislocation and reoperation in patients with osteonecrosis of the femoral head (ONFH) in a large cohort. We studied 4995 hip arthroplasties: total hip arthroplasty (THA) was performed in 79% of patients; bipolar hemiarthroplasty (BP), 17%; total resurfacing arthroplasty (tRS), 3%; and hemi-resurfacing arthroplasty (hRS), 1%. A new type of BP (accounting for 49% of BPs) comprised a femoral component with a polished or smooth, small-diameter (approximately 10 mm) neck with a round or oval axial cut surface and no sharp corners. The infection rate was relatively low (0.56%) even though 58% of cases of ONFH were associated with systemic steroid use, a known risk factor for infection. Post-operative dislocation occurred in 4.3% of cases, with re-operation needed in 3.9%. The dislocation rate was related to surgery type: 5.2% in THA, 0.9% in BP, and 0% in tRS and hRS. Among total arthroplasties with six month or longer follow-up (3670 THAs and 159 tRSs), the risk factors for post-operative dislocation were younger (≤ 40 years) or older (≥ 62 years) age, higher body weight, posterolateral approach, and smaller prosthetic head diameter. Regarding the need for re-operation, higher body weight and surgery type were identified as risk factors. The relatively high dislocation rate of 5.2% in THA is a cause for concern. The identified risk factors for dislocation should be considered when selecting THA for treatment. Prosthesis survivorship in hRSs was inferior to that in BPs or THAs. Body weight also affected the survivorship of hip arthroplasties.

Clinical outcome and quality of life after reoperative CABG: off-pump versus on-pump – observational pilot study

PubMed Central

2013-01-01

Background Coronary artery bypass grafting (CABG) on cardiopulmonary bypass (CBP) is associated with significant morbidity and mortality. In high-risk patients, doomed for reoperation the adverse effects of CBP may be more striking. We evaluated the results of reoperative CABG (redo-CABG) by either off-pump (OPCAB) or on-pump (ONCAB). Clinical endpoints were perioperative myocardial infarction, mortality, survival and as the most striking difference between prior studies the quality of life (QoL). Methods We performed a prospective, non-randomized assessment for patients who underwent redo-CABG by redo-OPCAB (n = 40) or redo-ONCAB (n = 40) at our institution between January 2007 and December 2010. For evaluation of QoL the SF-36 health survey was used with self-administered assessment. Results During follow-up 37 of 40 patients were alive in the redo-OPCAB group versus 32 of 40 patients in the redo-ONCAB group (p < 0.05). The shorter operation time, less blood loss, fewer perioperative myocardial infarctions, the higher rate of totally arterial revascularisation and shorter intensive care stay were the significantly beneficial differences for patients in the redo-OPCAB group (p < 0.05). The 3-year survival rate was higher in the redo-OPCAB group with 81 ± 12% versus 63 ± 9%in the redo-ONCAB group. The quality of life survey did not reveal any significant differences between both groups. Conclusion In conclusion, with our present retrospective study, we could demonstrate the safety and efficacy of the redo-OPCAB technique with even higher 3-year survival rate. Both techniques seem to have similar impact on the outcome of patients. PMID:23561396

The Ross procedure is seldom offered to adults less than 60 years of age who require aortic valve replacement except in a few high-volume centers with documented expertise. Inserting the pulmonary autograft as an unsupported root replacement may lead to increasing reoperations on the aortic valve in the second decade. Of 333 patients undergoing the Ross procedure between October 1992 and June 2012, the study group of 310 consecutive patients (mean age ± standard deviation, 39.3±12.7 years (limits 16-63) had the aortic root size adjusted to match the pulmonary autograft, which was inserted as a root replacement, with the aorta closed up around it to provide autologous support. The mean follow-up time was 9.4 years; the actuarial survival was 97% at 16 years; and freedom from the composite of all reoperations on the aortic valve and late echocardiographic-detected aortic regurgitation greater than mild was 95% at 5 years, 94% at 10 years, and 93% at 15 years. Overall freedom from all reoperations on aortic and pulmonary valves was 97% at 5 years, 94% at 10 years, and 93% at 15 years. All results were better for the patients presenting with predominant aortic stenosis (98% freedom at 15 years) than for those with aortic regurgitation (p=0.01). Autologous support of the pulmonary autograft leads to excellent results in the groups presenting with aortic stenosis and mixed aortic stenosis/regurgitation and to good results for those presenting with pure aortic regurgitation. The Ross procedure, using one of the proven, durable techniques available, should be considered for more widespread adoption. Copyright © 2013 The Society of Thoracic Surgeons.

Daily administration of vitamin D is important for maintaining bone homeostasis. The orthopedic community has shown increased interest in vitamin D supplementation and patient outcomes after fracture. The current study used data from a large hip fracture trial to determine the proportion of patients who consistently used vitamin D after hip fracture surgery and to determine whether supplementation was associated with improved health-related quality of life and reduced reoperation rates. The FAITH study is a multicenter trial of elderly patients with femoral neck fracture treated with internal fixation. The current study asked a subset of patients included in the FAITH study about vitamin D supplementation and categorized them as consistent users, inconsistent users, or nonusers. This study also evaluated whether supplementation was associated with improved quality of life and reduced reoperation rates. The final analysis included 573 patients (mean age, 74.1 years; female, 66.3%; nondis-placed fractures, 72.4%). A total of 18.7% of participants reported no use of vitamin D, 35.6% reported inconsistent use, and 45.7% reported consistent use. Adjusted analysis found that consistent supplementation was associated with a 2.42 increase of the Short Form-12 physical component score 12 months postoperatively (P=.033). However, supplementation was not associated with reduced reoperation rates (P=.386). Despite guidelines recommending vitamin D supplementation, a low proportion of elderly patients with hip fracture use vitamin D consistently, suggesting a need for additional strategies to promote compliance. This study found that the use of vitamin D was associated with a statistically significant but not clinically significant improvement in health-related quality of life after hip fracture. Further research is needed to confirm these findings. [Orthopedics. 2017; 40(5):e868-e875.]. Copyright 2017, SLACK Incorporated.

To evaluate the success rate of adjustable suture techniques in horizontal eye muscle surgery in children ≤15 years of age over a 19-year period by a single surgeon. The medical records of all consecutive patients in this age group who underwent horizontal eye muscle surgery from 1989 through 2012 were reviewed retrospectively. Patients were divided into two groups: those in whom a nonadjustable suture technique was used and those in whom adjustable sutures were used. The following data were collected: type of strabismus, preoperative measurements, postoperative results, and reoperation rates. A total of 116 cases in the nonadjustable group and 521 cases in the adjustable group were included. In the adjustable group, adjustment was performed in 63% of the cases, because of either an under- (41%) or overcorrection (22%). The adjustment procedure was performed under topical proparacaine in 15% of cases and under intravenous propofol in 85%. For the adjustable group, 3-5 minutes more per muscle intraoperatively and 15-20 minutes for adjustment were required. No complications were encountered during the adjustment procedures. Early success rate, defined as alignment within 8 Δ of straight at 3 to 6 months' postoperative follow-up, was significantly greater in the adjustable group than in the nonadjustable group (77.7% vs 64.6% [P ≤ 0.03]). Of the adjustable patients, 15% required reoperation compared with 21% of the nonadjustable patients. Use of adjustable sutures in horizontal eye muscle surgery in children ≤15 years of age provided an improved success rate and fewer reoperations compared with nonadjustable sutures.

Purpose Cephalomedullary nail (CM nail) in the treatment of femoral intertrochanteric fractures is in the lime light in recent years. The purpose of this study is to compare surgical outcomes between experienced surgeon and non-experienced surgeons in respect of CM nail for femoral intertrochanteric fractures. Materials and Methods The 129 patients underwent CM nail for femoral intertrochanteric fracture more than six months of follow-up from April 2011 to March 2014 in Seoul Medical Center (Seoul, Korea) were participated in this study. For this study, group A consisted of experienced surgeons who performed more than 500 times of CM nail, and group B consisted of non-experienced surgeons who performed less than 50 times of CM nail. Clinical and radiologic outcomes, complications and the need for reoperation between both groups were compared in the study. Results According to clinical result, both the mean operation time and transfusion volume were significantly longer and greater in group B (P<0.05). In the radiologic outcomes, adequacy of reduction, tip-apex distance and numbers of case placed in the Cleveland zones 5, 6 and 8; there was no statistical difference between both groups. Moreover, rate of complication and reoperation had same results as radiologic outcomes. Conclusion There was no significant difference with statistical data in complications from CM nail for femoral intertrochanteric fractures between experienced surgeon and non-experienced surgeon. Although the operation time and transfusion volume were significantly longer and greater in the case of operation by non-experienced surgeon, satisfactory performance was seen in the complications and the need for reoperation.

The clavicle exhibits considerable movement in three planes making rigid fixation challenging. The addition of a second plate may be considered to improve fixation rigidity, but risks compromising the blood supply to the fracture site. The purpose of this study is to assess if extraperiosteal dual plate fixation increases the rate of non-union, reoperation, and complications at 1 year for surgically treated acute mid-shaft clavicle fractures. Between June 1998 and June 2013, surgically treated mid-shaft clavicle fractures undergoing open reduction internal fixation within 4 weeks of injury were retrospectively reviewed. Patients undergoing single plate fixation were compared to dual plate fixation. Patients were followed for a minimum of 1 year. Charts were reviewed to assess union rates, reoperation, and complications. One hundred and sixty-three clavicles (125 single plates, 34 dual plates) were evaluated. All patients (100%) in dual plating group and one hundred and fourteen (91%) in single plating group obtained bony union by 1 year (p = 0.13). Six patients (4.8%) experienced a non-union in the single plating cohort compared to the dual plating cohort who had a 100% union rate. Seven patients required reoperation in the single plate cohort due to implant failure (N = 4), infection (N = 2), and non-union (N = 1). This limited series of patients demonstrates dual plate fixation is a reliable option for acute mid-shaft clavicle fractures, with excellent union rates and low complication rates. Compared to single plate fixation, no significant differences in outcomes were identified. In the case of more complex fracture patterns, application of a second extraperiosteal plate may be utilized without compromising healing or increasing complication rates.

The previously described Akademikliniken (AK) method is a comprehensive approach to breast augmentation with form stable implants that has been shown to afford favorable outcomes when applied by experienced surgeons. To evaluate outcomes of a surgeon newly adopting this method at the beginning of his career. A retrospective review of patients undergoing dual plane subpectoral augmentation with Style 410 implants between April 2009 and December 2014 was undertaken. The review was performed one year after the last operation. The first author (P.M.) performed all operations. Complications and reoperation rates were analyzed and correlated with patient and implant characteristics using the chi-square or Fisher's exact test, as appropriate. A total of 620 consecutive patients met the inclusion criteria with a mean follow up of 8 months (range, 1 week-60 months). Complications occurred in 14.8% of the patients: request for larger size (3.3%), rotation (3%), and Baker III/IV capsular contracture (2.2%) were the most common ones. Low implant projection was a statistically significant risk factor (P < 0.05) for the most common complication - request for a larger size. The overall reoperation rate was 8.7%. The most common indication for reoperation was request for larger size (2.2%) followed by rotation (2.2%) and capsular contracture (2%). Breast augmentation with form stable anatomical implants requires a considerably different process. By implementing a systematic approach such as the AK method, novices in this terrain can expect to achieve reasonable outcomes. 4. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

Deep sternal wound infection (DSWI) is a rare but life-threatening complication following cardiac surgery associated with increased morbidity and mortality. Management of these patients has evolved over the years and can include sternal rewiring, mediastinal irrigation, negative-pressure wound therapy (NPWT) dressing or repair with flaps. We reviewed changes in our management of DSWI and outcomes. Using the Australian and New Zealand Society of Cardiac and Thoracic Surgeons database, 5472 underwent cardiac surgery at St Vincent's Hospital, Melbourne, and 42 were identified as developing DSWI requiring re-operation between June 2002 and September 2014. Data were collected pertaining to risk factors for DSWI, management strategies and outcomes. Patients were compared from a period prior to NPWT dressing use (June 2002-February 2006, n = 14) and since the NPWT has been used regularly in the management of DSWI (from March 2006, n = 28). Patients were also compared based on the requirement for flap closure of their sternal wound. Because of the widespread use of NPWT dressings, there is a trend towards fewer sternal infections requiring flap closure (25 versus 42.8%) and less post-operative complications after definitive closure (7.1 versus 28.6%). Before and after widespread NPWT use, patients require similar number of re-operations before closure and have no significant differences in time to definitive closure or length of hospital stay. The use of NPWT dressings as a bridge to definitive closure may reduce the need for more burdensome flap reconstruction, does not delay definitive reconstruction or prolong hospital stay and may reduce post-reconstruction complications requiring re-operation. © 2015 Royal Australasian College of Surgeons.

Total thyroidectomy versus hemithyroidectomy for patients with follicular neoplasm. A cost-utility analysis.

PubMed

Thyroid nodules are a common condition. Overall, 20% of the nodules assessed with FNAB correspond to the follicular pattern. A partial thyroidectomy is the minimal procedure that should be performed to determine the nature of these nodules. Some authors have suggested performing a total thyroidectomy based on the elimination of reoperation and ultrasound follow-up. The aim of this study was to evaluate the most cost-useful surgical strategy in a patient with an undetermined nodule, assessing complications, reoperation, recurrence and costs. A cost-utility study was designed to compare hemithyroidectomy and total thyroidectomy. The outcomes were complications (definitive RLN palsy, permanent hypoparathyroidism, reoperation for cancer, and recurrence of the disease), direct costs and utility. We used the payer perspective at 5 years. A deterministic and probabilistic sensitivity analysis was completed. In a deterministic analysis, the cost, utility and cost-utility ratio was COP $12.981.801, 44.5 and COP $291.310 for total thyroidectomy and COP $14.309.889, 42.0 and $340.044 for partial thyroidectomy, respectively. The incremental cost-utility ratio was -$535.302 favoring total thyroidectomy. Partial thyroidectomy was more cost-effective when the risks of RLN injury and definitive hypoparathyroidism were greater than 8% and 9% in total thyroidectomy, respectively. In total, 46.8% of the simulations for partial thyroidectomy were located in the quadrant of more costly and less effective. Under a common range of complications, and considering the patient's preference and costs, total thyroidectomy should be selected as the most cost-effective treatment for patients with thyroid nodules and follicular patterns.

Emergency surgery for perforated peptic ulcer (PPU) is associated with significant morbidity and mortality. Accurate and early risk stratification is important. The primary aim of this study is to validate the various existing MRPMs and secondary aim is to audit our experience of managing PPU. 332 patients who underwent emergency surgery for PPU at a single intuition from January 2008 to December 2012 were studied. Clinical and operative details were collected. Four MRPMs: American Society of Anesthesiology (ASA) score, Boey's score, Mannheim peritonitis index (MPI) and Peptic ulcer perforation (PULP) score were validated. Median age was 54.7 years (range 17-109 years) with male predominance (82.5%). 61.7% presented within 24 h of onset of abdominal pain. Median length of stay was 7 days (range 2-137 days). Intra-abdominal collection, leakage, re-operation and 30-day mortality rates were 8.1%, 2.1%, 1.2% and 7.2% respectively. All the four MRPMs predicted intra-abdominal collection and mortality; however, only MPI predicted leak (p = 0.01) and re-operation (p = 0.02) rates. The area under curve for predicting mortality was 75%, 72%, 77.2% and 75% for ASA score, Boey's score, MPI and PULP score respectively. Emergency surgery for PPU has low morbidity and mortality in our experience. MPI is the only scoring system which predicts all - intra-abdominal collection, leak, reoperation and mortality. All four MRPMs had a similar and fair accuracy to predict mortality, however due to geographic and demographic diversity and inherent weaknesses of exiting MRPMs, quest for development of an ideal model should continue.

To evaluate the incidence and predictors of post-thyroidectomy definitive hypocalcemia and hypoparathyroidism. We assessed ionic calcium preoperatively and postoperatively (first, second and 30th day) in 333 patients undergoing thyroidectomy. In those presenting hypocalcemia, measurements were also made 90 and 180 days after surgery, when parathormone was also dosed. Patients were grouped according to the presence or absence of hypocalcemia and evaluated according to age, gender, thyroid function, thyroid volume, number of parathyroid glands identified and need to parathyroid reimplantation, type of operation, operative time, and histopathological diagnosis. The incidence of temporary hypocalcemia was 40.8% (136 patients), and of definitive hypoparathyroidism 4.2% (14 patients). Reoperation or total thyroidectomy, neck dissection, hyperthyroidism, operative time and age above 50 years were factors related to higher incidence of hypocalcemia and definitive hypoparathyroidism (p <0.05). predictors of postoperative hypocalcemia included age (> 50 years), total thyroidectomy, reoperation, neck dissection and operative time. The predictors of post-thyroidectomy definitive hypoparathyroidism included type of operation, histological diagnosis and hyperthyroidism.

Gouda, Biswanath P; Nelson, Thomas; Bhoyrul, Sunil

2012-08-01

Surgical myotomy is the gold standard in therapy for achalasia, but treatment failures occur and require revisional surgery. A MEDLINE search of peer-reviewed articles published in English from 1970 to December 2008 was performed using the following terms: esophageal achalasia, Heller myotomy, and revisional surgery. Thirty-three articles satisfied our inclusion criteria. A total of 12,727 patients, with mean age of 43.3 years (males 46% and females 50%), underwent Heller myotomy (open 94.8% and laparoscopic 5.2%). Revisional surgery was performed in 6.19%. Procedures performed included revision of the original myotomy or creation of a new myotomy with or without an antireflux procedure or esophagectomy. Reasons for reoperation were incomplete myotomy (51.8%), onset of reflux (34%), megaesophagus (16.2%), and esophageal carcinoma (3.04%). Systematic review of the literature for revisional surgery following Heller myotomy revealed a 6.19% rate of reoperation with a low mortality rate.

To analyze the use of this sponge in pediatric patients undergoing split-liver transplantation. Retrospective study, including 35 pediatric patients undergoing split-liver transplantation, divided into two groups according to the use of the sponge: 18 patients in Group A (no sponge) and 17 in Group B (with sponge). The characteristics of recipients and donors were similar. We observed greater number of reoperation due to bleeding in the wound area in Group A (10 patients - 55.5%) than in Group B (3 patients - 17.6%); p = 0.035. The median volume of red blood cells transfused in Group A was significantly higher (73.4 ± 102.38 mL/kg) than that in Group B (35.1 ± 41.67 mL/kg); p = 0.048. Regarding bile leak there was no statistical difference. The use of the human fibrinogen and thrombin sponge, required lower volume of red blood cell transfusion and presented lower reoperation rates due to bleeding in the wound area.

Pancreatic fistula( PF) is a challenging postoperative complication. We report a case of PF following gastrectomy successfully treated using intravenous coagulation factor XIII( FXIII).A 78-year-old man with early gastric cancer underwent total gastrectomy with Roux-en-Y reconstruction. PF developed postoperatively, following which, leakage from the duodenal stump was observed. Percutaneous drainage and re-operative surgery were performed. A somatostatin analogue, antibiotic drugs, and gabexate mesilate were administrated along with nutritional support. The pancreatic and duodenal fistula had been producing duodenal juice for over 30 days since the re-operative surgery. As suspected, reduced FXIII activity was confirmed in the patient. After administering FXIII for 5 days, the amount of duodenal juice from the fistula markedly reduced, and the fistula closed immediately afterwards. The results of our study suggest that administration of FXIII could be a reasonable and effective treatment for patients with pancreatic or/and enterocutaneous fistula who are resistant to standard treatments.

Anastomotic leak after colorectal surgery is a serious event associated with significant morbidity and mortality. There is little consensus regarding 'acceptable' rates of leakage, however. This study describes the experience of anastomotic leakage after both elective and emergency colorectal surgery in a district general hospital. A prospectively collected database of all patients with a diagnosis of colorectal cancer in a single hospital formed the basis of the study. Leak was defined as breakdown of the anastomosis contributing to death or requiring reoperation or reintervention. A total of 949 patients underwent surgery with an anastomosis between 1996 and 2004, including 331 patients treated with anterior resection. Anastomotic leaks requiring reoperation occurred in eight patients (0.8%). Thirty-day and in-hospital mortality was 4%. A very low rate of anastomotic leakage after colorectal surgery is possible in a district general hospital setting. Given the impact of anastomotic leakage on function, tumour recurrence and long-term survival, it should be considered as a marker of surgical quality when evaluating surgical performance.

Surgical treatment of atrioventricular canal defect.

1975-11-01

Fifty-nine patients with congenital anomalies of the atrioventricular canal underwent operation and all survivors were followed up. In 42 patients with partial atrioventricular canal defects, ten had preoperative congestive heart failure. Three, or 7.1%, died of endomyocardial fibroelastosis, high pulmonary vascular resistance, and severe mitral regurgitation. A fourth patient later died of Wolff-Parkinson-White syndrome and fibrilation. Reoperations in five patients were all successful. No patients had persistent atrioventricular blocks, and all patients are asymptomatic. Two of these subjects continue to receive digoxin therapy, and one of them is believed to have substantial mitral insufficiency. Of the 17 patients who had complete atrioventricular canal defects, 13 had a divided common anterior leaflet attached to the septum by chordae tendineae, and four had undivided and unattached anterior leaflets. Two had previously undergone pulmonary banding, and nine were treated for congestive heart failure. Six died after operation. There were no reoperations. No patient presently has required a pacemaker. Two subjects have persistent cardiomegaly.

To evaluate the role of the small intestinal decompression tube (SIDT) and Gastrografin in the treatment of early postoperative inflammatory small bowel obstruction (EPISBO). Twelve patients presented EPISBO after abdominal surgery in our department from April 2011 to July 2012. Initially, nasogastric tube decompression and other conventional conservative treatment were administrated. After 14 days, obstruction symptom improvement was not obvious, then the SIDT was used. At the same time, Gastrografin was injected into the small bowel through the SIDT in order to demonstrate the site of obstruction of small bowel and its efficacy. In 11 patients after this management, obstruction symptoms disappeared, bowel function recovered within 3 weeks, and oral feeding occurred gradually. Another patient did not pass flatus after 4 weeks and was reoperated. After postoperative follow-up of 6 months, no case relapsed with intestinal obstruction. For severe and long course of early postoperative inflammatory intestinal obstruction, intestinal decompression tube plus Gastrografin is safe and effective, and can avoid unnecessary reoperation.

Purpose To compare the five year outcomes of the Ahmed FP7 Glaucoma Valve (AGV) and the Baerveldt 101-350 Glaucoma Implant (BGI) for the treatment of refractory glaucoma. Design Multicenter randomized controlled clinical trial. Participants 276 patients, including 143 in the AGV group and 133 in the BGI group. Methods Patients 18 to 85 years of age with previous intraocular surgery or refractory glaucoma and intraocular pressure (IOP) of ≥ 18 mmHg in whom glaucoma drainage implant surgery was planned were randomized to implantation of either an AGV or BGI. Main Outcome Measures IOP, visual acuity, use of glaucoma medications, complications, and failure (IOP > 21 mmHg or not reduced by 20% from baseline, IOP ≤ 5 mmHg, reoperation for glaucoma, removal of implant, or loss of light perception). Results At 5 years, IOP (mean ± SD) was 14.7 ± 4.4 mmHg in the AGV group and 12.7 ± 4.5 mmHg in the BGI group (p = 0.012). The number of glaucoma medications in use at 5 years (mean ± SD) was 2.2 ± 1.4 in the AGV group and 1.8 ± 1.5 in the BGI group (p = 0.28). The cumulative probability of failure during 5 years of follow-up was 44.7% in the AGV group and 39.4% in the BGI group (p = 0.65). The number of subjects failing due to inadequately controlled IOP or reoperation for glaucoma was 46 in the AGV group (80% of AGV failures) and 25 in the BGI group (53% of BGI failures, p=0.003). Eleven AGV eyes (20% of AGV failures) experienced persistent hypotony, explantation of implant, or loss of light perception compared to 22 (47% of failures) in the BGI group. The 5-year cumulative reoperation rate for glaucoma was 20.8% in the AGV group compared to 8.6% in the BGI group (p=0.010). Change in logMAR Snellen visual acuity (mean ± SD) at 5 years was 0.42 ± 0.99 in the AGV group and 0.43 ± 0.84 in the BGI group (p=0.97). Conclusions Similar rates of surgical success were observed with both implants at 5 years. BGI implantation produced greater IOP reduction and a lower rate of glaucoma reoperation than AGV implantation but BGI implantation was associated with twice as many failures due to safety issues such as persistent hypotony, loss of light perception, or explantation.

The minimally invasive repair of pectus excavatum (MIRPE) has been widely accepted and has become a viable alternative to the open Ravitch technique. MIRPE has evolved over time with some advocating that a safe repair can be accomplished without direct visualization utilizing thoracoscopy. The MIRPE with and without a thoracoscopic approach has not been previously analyzed from a nationwide database to determine differences in safety and short-term outcomes. The American College of Surgeons National Surgical Quality Improvement Program-Pediatric (NSQIP-P) 2012-2015 database was used in identifying patients that had MIRPE using Current Procedural Terminology (CPT) codes and ICD-9CM/ICD-10CM postoperative diagnosis codes. Outcomes of interest were readmissions, reoperations, complications, cardiothoracic injury, operative time, and duration of hospital stay after surgery for MIRPE with and without thoracoscopy. Descriptive statistics, simple and multivariable logistic regressions, Fisher's exact, and Wilcoxon rank sum test were used to determine any differences in 30-day postoperative outcomes. There were 1569 MIRPE cases included. 15.9% (N=249) of MIRPE were done without thoracoscopy. There were no significant differences with the use of thoracoscopy compared to without thoracoscopy in the rate of readmissions (2.5 vs 4.8%; p=0.06), reoperations (1.4 vs 2.0%; p=0.57), postoperative complications (2.6% vs 3.2%; p=0.52), and cardiothoracic injuries (0.2% vs 0.0%; p=1.00). Unadjusted odds ratios (ORs) for readmission and reoperation comparing MIRPE with thoracoscopy to MIRPE without thoracoscopy were 0.51 (p<0.05) and 0.71 (p=0.50), respectively. Adjusted ORs were 0.49 (p=0.04) and 0.71 (p=0.50), respectively. There were no reported deaths, but two cardiothoracic injuries were recorded in the group with thoracoscopy. MIRPE with thoracoscopy was associated with longer operative time (mean 13.0min; p=0.00) and longer hospital stay (mean 0.37days; p<0.01) compared to MIRPE without thoracoscopy. No data were available for the severity of the pectus defect. MIRPE has a low adverse event rate with no difference in reoperations, postoperative complications, and cardiothoracic injuries with or without the use of thoracoscopy. There may be a higher rate of readmissions in the nonthoracoscopic group. While the technique used remains the surgeon's decision, the use of thoracoscopy may be unnecessary and is at an added cost.

Percutaneous endoscopic cervical discectomy (PECD) is regarded as an effective treatment modality in cervical disc herniation, including radicular pain and lateral location of disc herniation. This study aimed to evaluate the clinical and radiologic outcomes of PECD along with the causes of reoperation and the technique itself. Between January 2007 and November 2012, 101 patients underwent PECD at the Busan Wooridul Hospital. Three patients underwent a 2-level PECD. The mean follow-up period was 34 months (range, 18-72 months). The mean age was 46.1 years; the most common operation was at the C5-C6 level (n = 45), followed by C6-C7 (n = 35), C4-C5 (n = 16), and C3-C4 (n = 8). The clinical outcomes were evaluated via the visual analog scale of the neck and arm according to the Neck Disability Index and the modified Macnab criteria. Among 101 patients, 12 underwent an additional operation at the index level. Five patients had aggravated stenosis by disc height narrowing, 4 had recurred disc, 2 had remained disc, and 1 had sustained symptoms. After PECD, there was a significant improvement in the visual analog scale and Neck Disability Index scores (P < 0.001). According to the modified Macnab criteria, excellent concordance was achieved in 65 patients, good in 22, fair in 2, and poor in 12. The reoperation performed on 12 patients improved their clinical outcomes. The mean duration was 4.8 months (2 days to 18 months) until reoperation. There were 3 PECD revisions, 3 artificial disc replacements, 2 corpectomies, 2 anterior cervical discectomies and fusion with cages, and 2 transfers to another hospital. The common feature was older age (P = 0.016) and male sex (P = 0.031). Preoperative radiologic findings were characterized by the foraminal disc (P = 0.04), disc degeneration at the index level (P = 0.05), combined bony spur (P = 0.001), concomitant adjacent level degeneration (P = 0.019), cervical kyphosis (P = 0.015), and segmental angle deterioration after PECD (P = 0.038). No statistical correlation was seen between the operation level and herniation size (P > 0.05). In total, 87% patients showed successful clinical outcome. Poor and fair outcomes at initial PECD were overcome by revision surgery, which improved outcomes. Although PECD is a promising minimally invasive procedure for cervical disc treatment, the indications for PECD should be considered carefully. Copyright © 2017 Elsevier Inc. All rights reserved.

To assess the current evidence of effectiveness and safety of Single-incision mini-slings (TVT-S) versus transobturator tension-free vaginal tapes (TVT-O/TOT) in the management of female stress urinary incontinence (SUI). Literature searches were conducted for all randomized controlled trials (RCTs) comparing TVT-S and TVT-O/TOT from CNKI, CBM, VIP, MEDLINE, OVID, FMJS and Cochrane Library between November 1996 and November 2011. The Revman 5.1.0 software was used for Meta-analysis according to Cochrane system evaluation method. A total of 1545 females in 7 RCTs were included. Meta-analysis showed that no statistical differences existed in the rate of postoperative voiding dysfunction and dyspareunia between TVT-S and TVT-O/TOT (P > 0.05). But the rate of objective cure, re-operation, inner thigh and groin pain and de novo urgency were statistically significant (P < 0.05). As compared with TVT-O/TOT, TVT-S procedure is associated with less postoperative inner thigh and groin pain, but a lower objective cure rate and relatively higher rates of de novo urgency and re-operation.

ABSTRACT Background: Roux-en-Y gastric bypass is one of the most common bariatric surgery and leads to considerable weight loss in the first months. Aim: To quantify the main early postoperative complications in patients submitted to the gastric bypass. Method: Observational retrospective cohort. Data of 1051 patients with class II obesity associated with comorbidities or class III obesity submitted to the gastric bypass with 30 days of follow-up starting from the date of the surgery. Results: The age average was 36 years with a predominance of females (81.1%). The mean preoperative body mass index was 43 kg/m². The major complication was fistula (2.3%), followed by intestinal obstruction (0.5%) and pulmonary embolism (0.5%). Death occurred in 0.6% of the cases. Conclusion: In the period of 30 days after surgery the overall complication rate was 3.8%; reoperation was necessary in 2.6% and death occurred in 0.6%. Fistula was the main complication and the leading cause of hospitalization in intensive care unit, reoperation and death. PMID:27683781

Prophylactic incisional negative-pressure wound therapy use after ventral hernia repairs (VHRs) remains controversial. We assessed the impact of a modified negative-pressure wound therapy system (hybrid-VAC or HVAC) on outcomes of open VHR. A 5-year retrospective analysis of all VHRs performed by a single surgeon at a single institution compared outcomes after HVAC versus standard wound dressings. Multivariable logistic regression compared surgical site infections, surgical site occurrences, morbidity, and reoperation rates. We evaluated 199 patients (115 HVAC vs 84 standard wound dressing patients). Mean follow-up was 9 months. The HVAC cohort had lower surgical site infections (9% vs 32%, P < .001) and surgical site occurrences (17% vs 42%, P = .001) rates. Rates of major morbidity (19% vs 31%, P = .04) and 90-day reoperation (5% vs 14%, P = .02) were lower in the HVAC cohort. The HVAC system is associated with optimized outcomes following open VHR. Prospective studies should validate these findings and define the economic implications of this intervention. Copyright © 2015 Elsevier Inc. All rights reserved.

A systematic review and meta-analysis of mesh versus suture cruroplasty in laparoscopic large hiatal hernia repair

2015-01-01

Structured Abstract Background Equipoise exists regarding whether mesh cruroplasty during laparoscopic large hiatal hernia repair improves symptomatic outcomes compared to suture repair. Data Source Systematic literature review (MEDLINE and EMBASE) identified 13 studies (1194 patients; 521 suture and 673 mesh) comparing mesh versus suture cruroplasty during laparoscopic repair of large hiatal hernia. We abstracted data regarding symptom assessment, objective recurrence, and reoperation and performed meta-analysis. Conclusions The majority of studies reported significant symptom improvement. Data were insufficient to evaluate symptomatic versus asymptomatic recurrence. Time to evaluation was skewed toward longer follow-up after suture cruroplasty. Odds of recurrence (OR 0.51, 95% CI 0.30–0.87; overall p=0.014) but not need for reoperation (OR 0.42, 95% CI 0.13–1.37; overall p=0.149) were less after mesh cruroplasty. Quality of evidence supporting routine use of mesh cruroplasty is low. Mesh should be used at surgeon discretion until additional studies evaluating symptomatic outcomes, quality of life and long-term recurrence are available. PMID:26520872

Retrospective cohort study of a nationwide database. The primary objective was to summarize the use of surgical methods for lumbar herniated intervertebral disc disease (HIVD) at two different time periods under the national health insurance system. The secondary objective was to perform a cost-effectiveness analysis by utilizing incremental cost-effectiveness ratio (ICER). The selection of surgical method for HIVD may or may not be consistent with cost effectiveness under national health insurance system, but this issue has rarely been analyzed. The data of all patients who underwent surgeries for HIVD in 2003 (n = 17,997) and 2008 (n = 38,264) were retrieved. The surgical methods included open discectomy (OD), fusion surgery, laminectomy, and percutaneous endoscopic lumbar discectomy (PELD). The hospitals were classified as tertiary-referral hospitals (≥300 beds), medium-sized hospitals (30-300 beds), or clinics (<30 beds). ICER showed the difference in the mean total cost per 1% decrease in the reoperation probability among surgical methods. The total cost included the costs of the index surgery and the reoperation. In 2008, the number of surgeries increased by 2.13-fold. The number of hospitals increased by 34.75% (731 in 2003 and 985 in 2008). The proportion of medium-sized hospitals increased from 62.79% to 70.86%, but the proportion of surgeries performed at those hospitals increased from 61.31% to 85.08%. The probability of reoperation was highest after laminectomy (10.77%), followed by OD (10.50%), PELD (9.20%), and fusion surgery (7.56%). The ICERs indicated that PELD was a cost-effective surgical method. The proportion of OD increased from 71.21% to 84.12%, but that of PELD decreased from 16.68% to 4.57%. The choice of surgical method might not always be consistent with cost-effectiveness strategies, and a high proportion of medium-sized hospitals may be responsible for this change. 4.

The previous studies agree that minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) has better function outcomes, less blood loss, and shorter hospital stay, when compared to open-TLIF. However, there are no significance differences on operative time, complication, and reoperation rate between the two procedures. This could be from less relative literatures and lower grade evidence. The further meta-analysis is needed with more and higher grade evidences to compare the above two TLIF procedures. Prospective and retrospective studies that compared open-TLIF and MIS-TLIF were identified by searching the Medline, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang, and VIP database (the literature search comprised Medical Subject Heading terms and key words or Emtree term). The retrieval time ranged from the date when the database was founded to January 2015. Pooled risk ratios (RR s) and weighted mean differences (WMDs) with 95% confidence intervals were calculated for the clinical outcomes and perioperative data. Twenty-four studies (n = 1967 patients) were included in this review (n = 951, open-TLIF, n = 1016, MIS-TLIF). MIS-TLIF was associated with a significant decrease in the visual analog score (VAS)-back pain score (WMD = -0.44; P = 0.001), Oswestry Disabilities Index (WMD = -1.57; P = 0.005), early ambulation (WMD = -1.77; P = 0.0001), less blood loss (WMD = -265.59; P < 0.00001), and a shorter hospital stay (WMD = -1.89; P < 0.0001). However, there were no significant differences in the fusion rate (RR = 0.99; P = 0.34), VAS-leg pain (WMD = -0.10; P = 0.26), complication rate (RR = 0.84; P = 0.35), operation time (WMD = -5.23; P = 0.82), or reoperation rate (RR = 0.73; P = 0.32). MIS-TLIF resulted in a similar fusion rate with better functional outcome, less blood loss, shorter ambulation, and hospital stay; furthermore, it did not increase the complication or reoperation rate based on the existing evidence.

We measured a comprehensive set of outcome measures after different surgical procedures for painful chronic pancreatitis (CP) at long-term follow-up. Pain caused by CP can be alleviated through operative intervention with type of procedure depending on anatomical abnormalities. Outcome measures include functional (pain relief, quality of life [QoL]), medical (endo- and exocrine function), and clinical (reoperation) results reported by patient. A cross-sectional cohort of 223 consecutive patients who underwent surgical drainage, head resection, or left-sided pancreas resection, depending on anatomical abnormalities, was analyzed. Participating patients were reassessed during a prospectively scheduled outpatient clinic visit. At follow-up, 44 patients had died; 146 of 179 living patients consented to participate in the study. After 63 months (range: 14-268), 68% reported no or little pain, 19% reported intermediate pain, and 12% reported severe pain. Preoperative daily opioid use (OR: 3.04; 95% confidence interval [CI]: 1.09-8.49) and high numbers of preceding endoscopic procedures (OR [odds ratio]: 3.89; 95% CI: 1.01-14.9) were associated with persistent severe pain. Compared with the general population, physical more than mental QoL remained impaired (P < 0.05). At follow-up, endocrine insufficiency was present in 57% of patients and exocrine insufficiency was present in 77%. Independently, a head resection and a reoperation for any cause were moderately associated with new-onset diabetes (P < 0.1). Compared with patients who underwent left-sided resection, the risk of developing exocrine insufficiency after surgery was higher after drainage or head resection. After 20 months (interquartile range: 10-51) after surgery, 26 (12%) of 223 patients underwent 1 or more elective reoperations. Operative intervention for painful CP, tailored to anatomical abnormalities, results in excellent to fair long-term pain relief, but approximately 10% of patients do not respond. QoL scores remained slightly compromised. High preoperative pain levels, suggested through daily opioid use and high numbers of endoscopic procedures, are associated with less favorable outcome.

Postoperative intra-abdominal massive bleeding is a rare and life-threatening complication associated with pancreaticoduodenectomy. Completion pancreatectomy (CP) was usually performed during reexploration for the complication. The management could decrease the complications, such as the pancreatic leakage or intraluminal infection after reexploration, but could increase mortality during the perioperative period. It also could result in loss of pancreatic function forever. This study evaluated an alternative surgical management for intra-abdominal massive hemorrhage to prevent pancreas function, simplify the surgical processes, and decrease the mortality of relaparotomy. Outcome after pancreaticojejunal bridge-anastomosis (PJBA) performed between January 2006 and June 2009 was compared with that after CP performed between February 1984 and December 2005. Between February 1984 and June 2009, 963 patients underwent the Whipple procedure (PD) or pylorus-preserving pancreaticoduodectomy (PPPD). Pancreatic leakage occurred in 103 patients (10.7%); 22 cases (21.4%) developed into intra-abdominal massive bleeding. Nonsurgical procedures of transarterial embolization (TAE) were performed in ten (45.45%) patients, of whom one died (10%). Twelve (54.55%) underwent reoperation. Five had CP with one death (20%). Pancreatic remnant was preserved by pancreaticojejunal bridge-anastomosis (PJBA) in seven patients with no deaths. The reexploration time was 340 +/- 48.2 min vs. 247.9 +/- 40.8 min (P < 0.01) for CP and PJBA group and the blood loss was 2,180 +/- 526.3 ml vs. 1,628.6 +/- 325.1 ml (P < 0.05). In-hospital time for CP was less than that for PJBA (P < 0.05). All patients with CP still developed endocrine insufficiency ("brittle" diabetes) and diarrhea (exocrine insufficiency). There were no evidences of exocrine and endocrine insufficiency in patients with PJBA. Pancreaticojejunal bridge-anastomosis is an easy, simple, and safe procedure for intra-abdominal massive hemorrhage associated with pancreaticoduodenectomy. It could decrease the mortality of reoperation and preserve the pancreatic function.

Clinical and radiological related outcomes have been reported for Chevron osteotomy as correction for mild to moderate hallux valgus, but only for relatively small patient series. Moreover, evaluation of the patient's point of view has mostly been conducted by means of more physician-based outcome measures. The goal of this study was to evaluate the effect of the Chevron osteotomy for hallux valgus on patients' daily lives using the Foot and Ankle Outcome Score (FAOS) as a validated and a hallux valgus specific patient reported outcome measure (PROM). Secondary outcome measures were radiological correction, complication rate, and re-operations. All 438 Chevron procedures (336 patients), at two surgical hospital sites in the period between January 2010 and October 2014, were retrospectively evaluated with a follow-up of at least 6 months. Patients were invited to fill in a cross-sectional online FAOS. For the FAOS, a total response of 60% was achieved. The FAOS ranged between 71 and 88 with a follow-up of on average 36 months. Patients with an undercorrection of their hallux valgus (11.6% of the procedures) scored significantly lower on three subscales of the FAOS (range between 61 and 77 versus 72-84). Patients who had a reoperation (12.6% of the procedures) also scored significantly lower on four subscales: 58-100 versus 73-89. Postoperative radiological measurements improved significantly with a mean difference of 6.1 (5.9; 6.4) degrees for the intermetatarsal angle and 13.7 (13.0; 14.5) degrees for the hallux valgus angle. In this large study cohort, Chevron osteotomy for hallux valgus offers good PROM scores on FAOS. These scores were significantly lower in patients with radiological undercorrection or with a reoperation. Results of the FAOS appear to modulate with physician based outcomes and therapeutic incidents. Improvement of outcome may therefore well be possible by increased attention on these surgical details.

Our study aimed to determine whether the displacement and morphology of a fragment in femur fracture with Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association/32-B/32-C (AO/OTA/32-B/32-C) classification affect the outcomes following closed reduction and internal fixation with an interlocking nail. This was a retrospective study. The study was conducted at a Level III trauma centre. A total of 50 consecutive patients presenting femoral shaft fracture with AO/OTA-type 32-B/32-C were included in the present study. Patients were divided into two groups according to the displacement of the fragments. In the large displacement group, patients were further subgrouped according to whether a reversed morphology of the fragment was present. The radiographic union score of femur (RUSF), the mean union time and the re-operation rate were assessed. The union rate of small- and large-gap groups at 12 months postoperatively was 75.9% and 21.1%, respectively (p=0.000). The mean union time of those union cases in these two groups was 7.8 and 13.0 months, respectively (p=0.000). The union rate of the non-reversed and reversed groups at 12 months postoperatively was 30% and 11.1%, respectively (p=0.179). The mean RUSF at 12 months in the non-reversed and reversed groups was 8.8 and 8.3, respectively (p=0.590). However, we found that patients presenting a reversed fragment had an increased risk of more than one re-operation (p=0.030). A fragmentary displacement of >1cm in AO/OTA-type 32-B/32-C femoral shaft fracture after nailing affected bone healing. Among the large-gap group patients, an unreduced reverse fragment presented a negative prognostic factor for re-operation. Prognostic level III. Copyright © 2013 Elsevier Ltd. All rights reserved.

To determine the value of aortic valve repair rather than replacement for valve dysfunction, we assessed late outcomes of various repair techniques in the contemporary era. From January 2001 to January 2011, aortic valve repair was planned in 1,124 patients. Techniques involved commissural figure-of-8 suspension sutures (n = 63 [6.2%]), cusp repair with commissuroplasty (n = 481 [48%]), debridement (n = 174 [17%]), free-margin plication (n = 271 [27%]) or resection (n = 75) or both, or annulus repair with resuspension (n = 230 [23%]), root reimplantation (n = 252 [25%]), or remodeling (n = 35 [3.5%]). Planned repair was aborted for replacement in 115 patients (10%); risk factors included greater severity of aortic regurgitation (AR; p = 0.0002) and valve calcification (p < 0.0001). In-hospital outcomes for the remaining 1,009 patients included death (12 [1.2%]), stroke (13 [1.3%]), and reoperation for valve dysfunction (14 [1.4%]). Freedom from aortic valve reoperation at 1, 5, and 10 years was 97%, 93%, and 90%, respectively. Figure-of-8 suspension sutures, valve resuspension, and root repair and replacement were least likely to require reoperation; cusp repair with commissural sutures, plication, and commissuroplasty was most likely (p < 0.05). Survival at 1, 5, and 10 years was 96%, 92%, and 83%. Immediate postoperative AR grade was none-mild (94%), moderate (5%), and severe (1%). At 10 years after repair, AR grade was none (20%), mild (33%), moderate (26%), and severe (21%). Patients undergoing root procedures were less likely to have higher-grade postoperative AR (p < 0.0001). Valve repair is effective and durable for treating aortic valve dysfunction. Greater severity of AR preoperatively is associated with higher likelihood of repair failure. Commissural figure-of-8 suspension sutures and repair with annular support have the best long-term durability. Copyright © 2018 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Background: Current literature describing the periacetabular osteotomy (PAO) is mostly limited to retrospective case series. Larger, prospective cohort studies are needed to provide better clinical evidence regarding this procedure. The goals of the current study were to (1) report minimum 2-year patient-reported outcomes (pain, hip function, activity, overall health, and quality of life), (2) investigate preoperative clinical and disease characteristics as predictors of clinical outcomes, and (3) report the rate of early failures and reoperations in patients undergoing contemporary PAO surgery. Methods: A large, prospective, multicenter cohort of PAO procedures was established, and outcomes at a minimum of 2 years were analyzed. A total of 391 hips were included for analysis (79% of the patients were female, and the average patient age was 25.4 years). Patient-reported outcomes, conversion to total hip replacement, reoperations, and major complications were documented. Variables with a p value of ≤0.10 in the univariate linear regressions were included in the multivariate linear regression. The backward stepwise selection method was used to determine the final risk factors of clinical outcomes. Results: Clinical outcome analysis demonstrated major clinically important improvements in pain, function, quality of life, overall health, and activity level. Increasing age and a body mass index status of overweight or obese were predictive of improved results for certain outcome metrics. Male sex and mild acetabular dysplasia were predictive of lesser improvements in certain outcome measures. Three (0.8%) of the hips underwent early conversion to total hip arthroplasty, 12 (3%) required reoperation, and 26 (7%) experienced a major complication. Conclusions: This large, prospective cohort study demonstrated the clinical success of contemporary PAO surgery for the treatment of symptomatic acetabular dysplasia. Patient and disease characteristics demonstrated predictive value that should be considered in surgical decision-making. Level of Evidence: Therapeutic Level IV.

Background The role of reoperation for recurrent glioblastoma (GBM) remains unclear. Prospective studies are lacking. Here, we studied the association of clinical outcome with extent of resection upon surgery for recurrent GBM in the patient cohort of DIRECTOR, a prospective randomized multicenter trial comparing 2 dose-intensified temozolomide regimens at recurrence of GBM. Methods We analyzed prospectively collected clinical and imaging data from the DIRECTOR cohort (N = 105). Volumetric analysis was performed on gadolinium contrast-enhanced MRI as well as fluid attenuated inversion recovery/T2 MRI and correlated with PFS after initial progression (PFS2) and post-recurrence survival (PRS). Quality of life was monitored by the EORTC QLQ-C30 and QLQ-BN20 questionnaires at 8-week intervals. Results Seventy-one patients received surgery at first recurrence. Prognostic factors, including age, MGMT promoter methylation, and Karnofsky performance score, were balanced between patients with and without reoperation. Outcome in patients with versus without surgery at recurrence was similar for PFS2 (2.0 mo vs 1.9 mo, P = .360) and PRS (11.4 mo vs 9.8 mo, P = .633). Among reoperated patients, post-surgery imaging was available in 59 cases. In these patients, complete resection of contrast-enhancing tumor (N = 40) versus residual detection of contrast enhancement (N = 19) was associated with improved PRS (12.9 mo [95% CI: 11.5–18.2] vs 6.5 mo [95% CI: 3.6–9.9], P < .001) and better quality of life. Incomplete tumor resection was associated with inferior PRS compared with patients who did not undergo surgery (6.5 vs 9.8 mo, P = .052). Quality of life was similar in these 2 groups. Conclusion Surgery at first recurrence of GBM improves outcome if complete resection of contrast-enhancing tumor is achieved. PMID:26823503

Seventy-six patients with clinical diagnosis Graves' disease, reoperated in the Clinic of Endocrine Surgery over the period 1985 through 1996, are analyzed. Distribution by gender and age: 3 men with mean age 55.33 y (range 49-60), and 73 women at mean age 39.67 years (range 19-69). The scope of secondary operation includes: thyroidectomy--3 cases, subtotal thyroid resection--55, lobectomy with contralateral subtotal resection--2, and unilateral predominantly subtotal resection--16 cases. It is the purpose of the study to assay the underlying causes of surgical relapse in Graves' disease, its relationship to the radicalism of the intervention, thyrostatic therapy duration, and early and late postoperative complications associated with its removal. In 16 cases (21.05%) secondary operative intervention is done against the background of enhanced production of thyroid hormones. A short 3 to 6-month thyrostatic course precedes the reoperation in eleven patients (14.47%). Unilateral thyroid resection is resorted to in 16 patients (21.05%). Postoperative hypothyroidism is observed in 6 cases (7.89%). A relapse of Graves' disease after reoperation is noted in 3 instances (3.94%). Six patients of the series reviewed (7.89%) develop postoperative hypoparathyroidism: transitory in four (5.26%) and permanent in two (2.63%). In the early postoperative period, paresis of n recurrents (n laryngeus inferior) develops in 2 patients (2.63%): left- and rightside, one each respectively. In terms of morphological patterns, the ensuing relapses after surgery in Graves' disease patients portray the initial pathological process: some cases show a tendency of nodular adenomatous hyperplasia development, sporadic cases form follicular adenomas, and in 14 cases (18.42%) lymphoid infiltrates predominate with a tendency to be converted into Hashimoto's thyroiditis. The presence of enhanced proliferative response induced by a variety of factors, therapeutic ones inclusive, is the basic morphological factor of the recurrent conditions described.

Controversy remains over whether anterior cervical discectomy and fusion (ACDF) or posterior cervical foraminotomy (PCF) is superior for the treatment of cervical radiculopathy. We therefore performed a systematic review including three prospective randomized controlled trails (RCT) and seven retrospective comparative studies (RCoS) by searching PubMed and EMBASE. These studies were assessed on risk of bias according to the Cochrane Handbook for Systematic Reviews of Interventions, and the quality of evidence and level of recommendation were evaluated according to the GRADE approach. Clinical outcomes, complications, reoperation rates, radiological parameters, and cost/cost-utility were evaluated. The mean complication rate was 7% in the ACDF group and 4% in the PCF group, and the mean reoperation rate was 4% in the ACDF group and 6% in the PCF group within 2 years of the initial surgery. There was a strong level of recommendation that no difference existed in clinical outcome, complication rate and reoperation rate between the ACDF and the PCF group. There was conflicting evidence that the ACDF group had better clinical outcomes than the PCF group (one study with weak level of recommendation). PCF could preserve the range of motion (ROM) of the operated segment but did not increase the ROM of the adjacent segment (weak level of recommendation). Meanwhile, the average cost or cost-utility of the PCF group was significantly lower than that of the ACDF group (weak level of recommendation). In conclusion, the PCF was just as safe and effective as the ACDF in the treatment of cervical radiculopathy. Meanwhile, PCF might have lower medical cost than ACDF and decrease the incidence of adjacent segment disease. Based on the available evidence, PCF appears to be another good surgical approach in the treatment of cervical radiculopathy. © 2016 Chinese Orthopaedic Association and John Wiley & Sons Australia, Ltd.

AES mobile-bearing total ankle replacement was developed from the Buechel Pappas model. It was withdrawn in 2009, after identification of a higher than expected complication rate. The purpose of the current study was to analyse clinical outcomes, failures and survival of the initial series of 50 AES published in 2009. In this single-centre continuous prospective study (2003-2006), 50 AES prostheses were included. Pre-operative osteoarthritis was mainly post-traumatic (50%) and secondary to instability (36%). All patients were assessed with clinical and radiographic follow-up at six months, one year, two years and every two to three years thereafter. A CT-scan was systematically performed before procedure, and at two years, five years and ten years. At last follow-up, all patients with TAR had a functional (SF 36, AOFAS) and clinical assessment. All complications or surgical events were analysed. The mean follow-up was ten ± two years (range, 9-13). The mean AOFAS score was 75 points (range, 26-100). The mean SF 36 score was 69 points (range, 35-97). There was a significant deterioration in AOFAS score at five years and at last follow-up (p < 0.05). Fifteen TARs underwent reoperation for cyst curettage-graft because of development of periprosthetic lesions. Six of them ended up with prosthesis removal-arthrodesis. At the last follow-up, 14 TARs were removed for arthrodesis. Of the 30 prostheses seen at last follow-up, four are awaiting prosthesis removal-arthrodesis and one for cyst curettage-graft. The ten year survivorships free of any prosthesis removal or arthrodesis and free of any reoperation were 68% (95% CI, 55-85) and 57% (95% CI, 44-74), respectively. Our data suggested a high rate of reoperation. Overall ten year survival was lower than with other designs, particularly due to cyst lesions. Level IV, prospective case series.

(1) To determine the radiographic correction/healing rate, patient-reported outcomes, reoperation rate, and complication rate after distal femoral osteotomy (DFO) for the valgus knee with lateral compartment pathology. (2) To summarize the reported results of medial closing wedge and lateral opening wedge DFO. We conducted a systematic review of PubMed, MEDLINE, and CINAHL to identify studies reporting outcomes of DFOs for the valgus knee. Keywords included "distal femoral osteotomy," "chondral," "cartilage," "valgus," "joint restoration," "joint preservation," "arthritis," and "gonarthrosis." Two authors first reviewed the articles; our study exclusion criteria were then applied, and the articles were included on the basis relevance defined by the aforementioned criteria. The Methodological Index for Nonrandomized Studies scale judged the quality of the literature. Sixteen studies were relevant to the research questions out of 191 studies identified by the original search. Sixteen studies were identified reporting on 372 osteotomies with mean follow-up of 45 to 180 months. All studies reported mean radiographic correction to a near neutral mechanical axis, with 3.2% nonunion and 3.8% delayed union rates. There was a 9% complication rate and a 34% reoperation rate, of which 15% were converted to arthroplasty. There were similar results reported for medial closing wedge and lateral opening wedge techniques, with a higher conversion to arthroplasty in the medial closing wedge that was confounded by longer mean follow-up in this group (mean follow-up 100 v 58 months). DFOs for the valgus knee with lateral compartment disease provide improvements in patient-reported knee health-related quality of life at midterm follow-up but have high rates of reoperation. No evidence exists proving better results of either the lateral opening wedge or medial closing wedge techniques. Level IV, systematic review of Level IV studies.

The Mosaic bioprosthesis (Medtronic Inc., Minneapolis, Minnesota, United States), a stented porcine aortic valve, combines glutaraldehyde fixation with zero-pressure, root-pressure techniques and antimineralization treatment with amino-oleic acid for improved hemodynamics and tissue durability. The first device has been implanted worldwide at the authors' institution in September 1993. The aim of the present study was to collect mid- to long-term data of the prosthesis. A total of 272 patients (124 males and 148 females) underwent isolated aortic valve replacement with the Mosaic bioprosthesis between September 1993 and August 2007. Median age at implant was 76.8 years (range, 31.3 to 90.7). Median follow-up was 12.0 years (range, 0 to 17.2 years); follow-up was complete for 223 (82%) patients. Early mortality (30 days) was 4% (12 patients). Overall survival at 5, 10, 15, and 17 years was 68.6% ± 3.1%, 36.4% ± 3.3%, 17.1% ± 3.6%, and 10.7% ± 4.3%, respectively. Eleven late deaths (5%) were cardiac related. There were 24 thromboembolic events, 1 hemorrhagic, and 6 reoperations/explants. At a median follow-up of 12 years, freedom from any cause of death was 27.0% ± 3.2% acting as a competing risk for the incidence of thromboembolic events (16.4% ± 3.5%), hemorrhage (0.5% ± 0.5%), and reoperation/explant (4.1% ± 1.8%). Two redos were due to structural valve deterioration (SVD), two for nonstructural dysfunction (paravalvular leakage), one for thrombosed prosthesis, and one for endocarditis. Performance and late outcome of the Mosaic bioprosthesis was satisfactory during 17 years after clinical introduction. The Mosaic bioprosthesis showed low incidence of SVD or need for reoperation in the long term. Georg Thieme Verlag KG Stuttgart · New York.

Retrospective review. The aim of our study was to quantify the frequency of complications associated with recombinant human bone morphogenetic protein 2 (rhBMP-2) use in anterior lumbar interbody fusion (ALIF). The orthopedic subset of the Medicare database (PearlDiver) was queried for this retrospective cohort study using International Statistical Classification of Diseases 9 (ICD-9) and Current Procedure Terminology (CPT) codes for ALIF procedures with and without rhBMP-2 between 2005 and 2010. Frequencies of complications and reoperations were then identified within 1 year from the index procedure. Complications included reoperations, pulmonary embolus, deep vein thrombosis, myocardial infarction, nerve-related complications, incision and drainage procedures, wound, sepsis, pneumonia, urinary tract infections, respiratory, heterotopic ossification, retrograde ejaculation, radiculopathy, and other medical complications. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the statistical significance. We identified a total of 41 865 patients who had an ALIF procedure. A total of 14 384 patients received rhBMP-2 while 27 481 did not. Overall, 6016 (41.8%) complications within 1 year from surgery were noted within the group who received rhBMP-2 and 12 950 (47.1%) complications within 1 year from surgery were recorded in those who did not receive rhBMP-2 (OR = 0.81, CI = 0.77-0.84). Overall, exposure to rhBMP-2 was associated with significantly decreased odds of complications with exception to reoperation rates (0.9% rhBMP-2 vs 1.0% no rhBMP-2; OR = 0.88, CI = 0.71-1.09) and radiculopathy (4.4% rhBMP-2 vs 4.3% no rhBMP-2; OR = 1.02, CI = 0.93-1.13). The use of rhBMP-2 in patients undergoing ALIF procedure was associated with a significantly decreased rate of complications. Further studies are needed to elucidate a true incidence of complication.

The purpose of this study was to evaluate whether high mammographic density can be used as one of the selection criteria for MRI in invasive lobular breast cancer (ILC). In our institute, high breast density has been used as one of the indications for performing MRI scan in patients with ILC. We divided the patients in two groups, one with MRI performed pre-operatively and other without MRI. We compared their surgical procedures and analyzed whether surgical plan was altered after MRI. In case of alteration of plan, we analyzed whether the change was adequate by comparing post-operative histological findings. Between 2011 and 2015, there were a total of 1601 breast cancers with 97 lobular cancers, out of which 36 had pre-operative MRI and 61 had no MRI scan. 12 (33.3%) had mastectomy following MRI, out of which 9 (25%) had change in surgical plan from conservation to mastectomy following MRI. There were no unnecessary mastectomies in the MRI group. However, utilization of MRI in this cohort of patients did not reduce reoperation rate (19.3%). Lobular carcinoma in situ (LCIS) was identified in 60% of reoperations on post-surgical histology. Patients in the "No MRI" group had higher mastectomy rate 26 (42.6%), which was again appropriate. High mammographic density is a useful risk stratification criterion for selective MRI in ILC within a multidisciplinary team meeting setting. Provided additional lesions identified on MRI are confirmed with biopsy, pre-operative MRI does not cause unnecessary mastectomies. Used in this selective manner, reoperation rates were not eliminated, albeit reduced when compared to literature. High mammographic breast density can be used as one of the selection criteria for pre-operative MRI in ILC without an increase in inappropriate mastectomies with potential time and cost savings. In this cohort, re-excisions were not reduced markedly with pre-operative MRI.

The purpose of this study was to determine failure rates, functional outcomes, and risk factors for failure after revision anterior shoulder stabilization surgery in high-risk adolescent athletes. Adolescent athletes who underwent primary anterior shoulder stabilization were reviewed. Patients undergoing subsequent revision stabilization surgery were identified and analyzed. Failure rates after revision surgery were assessed by Kaplan-Meier analysis. Failure was defined as recurrent instability requiring reoperation. Functional outcomes included the Marx activity score; American Shoulder and Elbow Surgeons score; and University of California, Los Angeles score. The characteristics of patients who required reoperation for recurrent instability after revision surgery were compared with those of patients who required only a single revision to identify potential risk factors for failure. Of 90 patients who underwent primary anterior stabilization surgery, 15 (17%) had failure and underwent revision surgery (mean age, 16.6 years; age range, 14 to 18 years). The mean follow-up period was 5.5 years (range, 2 to 12 years). Of the 15 revision patients, 5 (33%) had recurrent dislocations and required repeat revision stabilization surgery at a mean of 50 months (range, 22 to 102 months) after initial revision. No risk factors for failure were identified. The Kaplan-Meier reoperation-free estimates were 86% (95% confidence interval, 67% to 100%) at 24 months and 78% (95% confidence interval, 56% to 100%) at 48 months after revision surgery. The mean final Marx activity score was 14.8 (range, 5 to 20); American Shoulder and Elbow Surgeons score, 82.1 (range, 33 to 100); and University of California, Los Angeles score, 30.8 (range, 16 to 35). At 5.5 years' follow-up, adolescent athletes had a high failure rate of revision stabilization surgery and modest functional outcomes. We were unable to convincingly identify specific risk factors for failure of revision surgery. Level IV, retrospective therapeutic case series.

Mitral valve replacement using a bioprosthesis remains controversial in young patients because data on long-term outcomes are missing. This study evaluated the long-term results of the PERIMOUNT pericardial mitral bioprosthesis in patients aged 65 years or younger. From 1984 to 2010, 148 Carpentier-Edwards PERIMOUNT mitral bioprostheses were implanted in 148 patients aged 65 years or younger. Baseline clinical, perioperative and follow-up data were recorded prospectively. Structural valve deterioration (SVD) was defined by strict echocardiographic assessment. The mean follow-up period was 8.6 ± 5.5 years, for a total of 1269 valve-years. Operative mortality rate was 2.0%. Fifty-one late deaths occurred (linearized rate 4.0% per valve-year). Actuarial survival rates averaged 70 ± 4%, 53 ± 6% and 31 ± 7% after 10, 15 and 20 years of follow-up, respectively. Actuarial freedom from SVD at 10, 15 and 20 years was 78 ± 5%, 47 ± 7% and 19 ± 7%, respectively. Reoperation was associated with no operative mortality. Actuarial freedom from reoperation due to SVD at 10, 15 and 20 years was 82 ± 4%, 50 ± 6% and 25 ± 8%, respectively. Competing risk analysis demonstrated an actual risk of explantation secondary to SVD at 20 years of 44 ± 5%. Expected valve durability was 14.2 years for this age group. In the selected patients aged 65 years or younger undergoing mitral valve replacement with a pericardial bioprosthesis, the expected valve durability was 14.2 years. Reoperation for SVD was associated with a low risk of mortality. © The Author(s) 2018. Published by Oxford University Press on behalf of the European Association for Cardio-Thoracic Surgery.

The risks vs benefits of tricuspid valve (TV) surgery in reoperative patients requiring left-sided valve surgery and moderate-to-severe tricuspid regurgitation is unclear. We compared patients with and without concomitant TV surgery. A total of 200 patients with moderate-to-severe TV regurgitation had reoperative left-sided valve procedures from January 2002 to April 2014; 75 with TV intervention (TVI) and 125 with no tricuspid intervention (TVN). Propensity-matched cohorts of 60 TVI and 60 TVN patients were compared. Outcomes included New York Heart Association class, TV regurgitation and survival. TVI patients were younger (66 ± 15 vs 72 ± 13 years, P < 0.001), had more cardiogenic shock (6 of 75, vs 0 of 125, P < 0.001) and mitral valve surgery (60 of 75 vs 69 of 125, P < 0.001). Propensity matching yielded 60 pairs of TVI cases and TVN controls. Matched groups were comparable in age (TVI = 67 ± 13 vs TVN 68 ± 14 years, P = 0.67), cardiogenic shock (2 vs 0, P = 0.50), and mitral valve surgery (15 each, P = 1.0). Operative mortality was 2 of 60 in TVI vs 10 of 60 TVN (P = 0.27). Median follow-up was 4.4 years. Follow-up rates of New York Heart Association class III-IV were similar (12 of 60 for TVI vs 16 of 60 TVN, P = 0.52). Kaplan-Meier analysis indicated improved event-free survival for TVI patients (6 years, 95% CI: 4.8-7.2 years vs 8 years, 95% CI: 6.7-9.3 years for TVN, P = 0.030). There was a trend towards increased TR at follow-up in patients with valve repair alone vs annuloplasty (P = 0.15). TV surgery was performed more often in higher-risk patients. Matched case-control analyses showed TVI was associated with improved midterm outcomes. Our data suggest that annuloplasty was preferable to TV repair alone. Copyright © 2016 Elsevier Inc.

The decision to repair mild-to-moderate functional tricuspid regurgitation (TR) during mitral valve surgery remains controversial. We evaluated the effects of tricuspid valve (TV) repair for functional mild-to-moderate TR during mitral valve surgery. We enrolled 959 patients with mild-to-moderate functional TR who underwent mitral valve surgery with (repair group n = 431) or without (control group n = 528) concomitant TV repair from January 1994 to September 2010. There were no significant differences in early mortality or major morbidity rates. Median follow-up was 64.8 months (range, 0.03-203.6 months). After adjustment for baseline characteristics using a propensity score adjustment model, the repair group had similar risks for TV reoperation (hazard ratio [HR], 0.46; 95% confidence interval [CI], 0.10-2.07; P = .31); congestive heart failure (HR, 1.12; 95% CI, 0.37-3.36; P = .84); death (HR, 1.41; 95% CI, 0.82-2.42; P = .22); and the composite of death, TV reoperation, and congestive heart failure (HR, 1.24; 95% CI, 0.76-2.03; P = .39) compared with the control group. On multivariate Cox-regression analysis, old age, atrial fibrillation without a Maze procedure, diabetes mellitus, chronic renal failure, poor left ventricular ejection fraction, and redo surgery emerged as significant independent risk factors for the composite outcome of death, TV reoperation, and congestive heart failure. Early or late clinical benefits of concomitant TV repair for mild-to-moderate TR during mitral valve surgery were uncertain through a long-term follow-up of 959 patients. Several preoperative factors and the performance of Maze procedure for AF seem to be more important than TV repair in overall clinical outcomes.

Axial flow left ventricular assist device (LVAD) implantation is an effective therapy for patients with advanced heart failure. As the preoperative hepatic and renal function play a critical role in determining adverse events after LVAD implantation, we analyzed the predictive role of the model for end-stage liver disease (MELD) score in determining in-hospital mortality after surgery. One hundred twenty-six patients underwent implant of an LVAD at our institution. Their individual preoperative MELD scores and perioperative total blood product usage (TBPU) were calculated. As LVAD implant as a reoperation is known to influence postoperative bleeding and mortality independently, the patients were divided into group I (first cardiac surgery) and group II (reoperative surgery). Group I: LVAD implantation was performed in 68/126 (54%) patients as their first cardiac surgery. The mean MELD score was 16.3 ± 6. Median TBPU for this group was 20.7 (0, 135) units. Inhospital mortality/30-day mortality was 4/68 (5.8%). Increasing MELD score (c-statistic = 0.88) and TBPU were found to be predictors of early mortality. An increasing MELD score was associated with more TBPU (p < 0.01) with a 10.9 ± 3 TBPU increase per a 10 unit rise in the MELD score. Group II: Of the 126 patients, 58 (46%) underwent LVAD implantation as a reoperation. Mean MELD score for these patients was 16 ± 5. Inhospital mortality/30-day mortality in this group was 12% and median TBPU was 30 (4,153) units. The MELD score was not predictive of inhospital mortality in these patients (p = 0.97). The MELD score is predictive of early mortality in patients undergoing LVAD implantation as their first cardiac surgery. Use of this score to select patients for LVAD implantation may be appropriate.

The aim of this study was to present a modified Murray and Schwarz 2.5-mm Kirschner wire (K-wire) intramedullary (IM) technique for fixation of displaced midshaft clavicle fractures (DMCF), and to compare the differences in treatment outcome of two-part (Robinson 2B.1) and multifragmentary (Robinson 2B.2) DMCF. A retrospective analysis of 91 patients who underwent IM fixation with a 2.5-mm K-wire for DMCF and had a 1-year post-operative follow-up between 2000 and 2012 was performed. The patients were allocated into two groups: Robinson 2B.1 (n = 64) and Robinson 2B.2 (n = 27). Assessed outcomes were non-union, reoperation rate, wire migration and infection. There was no statistically significant difference in the rate of non-union (2B.1,2B.2; 3.13%, 7.41%; p = 0.365), reoperation (2B.1, 2B.2; 3.13%, 7.41%; p = 0.365), K-wire migration (2B.1, 2B.2; 0.00%, 0.00%; p = 1.00) and clavicle shortening at 12-months (2B.1, 2B.2; 3.13%, 7.41%; p = 0.365). Intramedullary clavicle fixation with a 2.5-mm K-wire is a safe surgical technique. 2B.1 injuries treated with 2.5-mm IM K-wire fixation have relatively improved outcome compared with displaced 2B.2 fractures for both non-union and reoperation rates. There were no occurrences of implant migration with either 2B.1 or 2B.2 injuries, and a non-significant difference in implant irritation was documented with IM K-fixation. The non-union rate with K-wire IM fixation of 2B.1 injuries concords with the published results of other IM devices and thus this technique should be added to the surgeon's armamentarium when considering surgical treatment of such injuries. © 2017 Elsevier Ltd.

The purpose of this investigation was to determine whether arthroscopic debridement of primary elbow osteoarthritis results in statistically significant and clinically relevant improvement in (1) elbow range of motion and (2) clinical outcomes with (3) low complication and reoperation rates. A systematic review was registered with PROSPERO and performed using PRISMA guidelines. Databases were searched for studies that investigated the outcomes of arthroscopic debridement for the treatment of primary osteoarthritis of the elbow in adult human patients. Study methodological quality was analyzed. Studies that included post-traumatic arthritis were excluded. Elbow motion and all elbow-specific patient-reported outcome scores were eligible for analysis. Comparisons between preoperative and postoperative values from each study were made using 2-sample Z-tests (http://in-silico.net/tools/statistics/ztest) using a P value < .05. Nine articles (209 subjects, 213 elbows, 187 males, 22 females, mean age 45.7 ± 7.1 years, mean follow-up 41.7 ± 16.3. months; 75% right, 25% left; 79% dominant elbow, 21% nondominant) were analyzed. Elbow extension (23.4°-10.7°, Δ 12.7°), flexion (115.9°-128.7°, Δ 12.8°), and global arc of motion (94.5°-117.6°, Δ 23.1°) had statistically significant and clinically relevant improvement following arthroscopic debridement (P < .0001 for all). There was also a statistically significant (P < .0001) and clinically relevant improvement in the Mayo Elbow Performance Score (60.7-84.6, Δ 23.9) postoperatively. Six patients (2.8%) had postoperative complications. Nine (4.2%) underwent reoperation.

To determine whether concurrently performed operations are associated with an increased risk for adverse events. Concurrent operations occur when a surgeon is simultaneously responsible for critical portions of 2 or more operations. How this practice affects patient outcomes is unknown. Using American College of Surgeons' National Surgical Quality Improvement Program data from 2014 to 2015, operations were considered concurrent if they overlapped by ≥60 minutes or in their entirety. Propensity-score-matched cohorts were constructed to compare death or serious morbidity (DSM), unplanned reoperation, and unplanned readmission in concurrent versus non-concurrent operations. Multilevel hierarchical regression was used to account for the clustered nature of the data while controlling for procedure and case mix. There were 1430 (32.3%) surgeons from 390 (77.7%) hospitals who performed 12,010 (2.3%) concurrent operations. Plastic surgery (n = 393 [13.7%]), otolaryngology (n = 470 [11.2%]), and neurosurgery (n = 2067 [8.4%]) were specialties with the highest proportion of concurrent operations. Spine procedures were the most frequent concurrent procedures overall (n = 2059/12,010 [17.1%]). Unadjusted rates of DSM (9.0% vs 7.1%; P < 0.001), reoperation (3.6% vs 2.7%; P < 0.001), and readmission (6.9% vs 5.1%; P < 0.001) were greater in the concurrent operation cohort versus the non-concurrent. After propensity score matching and risk-adjustment, there was no significant association of concurrence with DSM (odds ratio [OR] 1.08; 95% confidence interval [CI] 0.96-1.21), reoperation (OR 1.16; 95% CI 0.96-1.40), or readmission (OR 1.14; 95% CI 0.99-1.29). In these analyses, concurrent operations were not detected to increase the risk for adverse outcomes. These results do not lessen the need for further studies, continuous self-regulation and proactive disclosure to patients.

Incisional hernia is a frequent late complication after open abdominal aortic aneurysm (AAA) repair. We aimed to determine whether prophylactic mesh reinforcement of the abdominal wall at open AAA repair via midline laparotomy reduces the rate of incisional hernia compared to standard sutured closure. A systematic review and meta-analysis was carried out in accordance with the PRISMA statement (PROSPERO registration CRD42017072508). Randomised controlled trials (RCTs) comparing prophylactic mesh reinforcement with standard sutured closure were eligible for inclusion. MEDLINE, Embase, and the Cochrane Library were searched. A meta-analysis with a random effects model was carried out to estimate pooled risk ratios (RR) with 95% confidence intervals (CIs) for the incidence of, and re-operation rate for, incisional hernias. Assessments of methodological quality, quality of evidence, and strength of recommendations were done with the Cochrane Collaboration's tool for assessing risk of bias and the GRADE approach. Four RCTs with a total of 388 patients were included in the meta-analysis. Pooled analysis showed that mesh reinforcement significantly reduced the risk of incisional hernia after AAA repair compared with standard sutured closure (RR 0.27, 95% CI 0.11-0.66). The pooled rate of re-operations was not different between groups (RR 0.23, 95% CI 0.11-1.05). Mesh reinforcement did not cause more intra-operative or post-operative complications than sutured closure. The risk of bias in studies was low and the quality of evidence was rated as moderate. Prophylactic mesh reinforcement of the abdominal wall after open AAA repair via midline laparotomy significantly reduces the risk of incisional hernia. However, no significant difference in re-operation for incisional hernia was found. Copyright © 2018 European Society for Vascular Surgery. Published by Elsevier B.V. All rights reserved.

Background Thrombosis is a complication of prosthetic valves on oral anticoagulants which is associated with significant morbidity and mortality. A re-operation carries a substantial risk, with mortality rate from 10% to 15% in selected series, which may be 2- or 3-folds higher in critically ill patients. This study conducted in a tertiary care cardiology unit aimed to evaluate the effectiveness and safety of thrombolytic therapy in stuck mitral bileaflet heart valves. Methods As a prospective observational study, clinical symptoms and fluoroscopy were the mainstay in diagnosis of stuck mitral valve. Gradient across the valve by transthoracic echocardiography was used to monitor the therapy every 6 h. Fall of mean gradient more than 50% was considered as successful thrombolysis. And final results were again checked by fluoroscopy with documentation of improved leaflet movement. Results Totally we studied 34 patients. Patients receiving thrombolytic therapy with streptokinase achieved an overall 91.2% freedom from a repeat operation or major complications, a large subcutaneous hematoma occurred in one ( 2.9%), reoperation required in two due to failure of treatment (5.9%), allergic reaction in one (2.9%), one patient developed transient neurologic dysfunction (2.9%) and one patient died during therapy due to refractory cardiogenic shock(2.9%). All patients including those with delayed presentation (> 14 days) and hemodynamically unstable patients had good results similar to those who presented within 14 days and hemodynamically stable. Mortality was higher in unstable patients and reoperation was higher with delayed presentation. Conclusions Thrombolysis with streptokinase is highly successful and safe therapy in hemodynamically stable as well as unstable patients, or those with early or delayed presentation with stuck bileaflet mitral valves, especially in centers where round the clock cardiothoracic surgery backup is not available.

To compare short- and long-term outcome after 180-degree laparoscopic anterior fundoplication (180-degree LAF) with laparoscopic Nissen fundoplication (LNF). LNF is currently the most frequently performed surgical therapy for gastroesophageal reflux disease. Alternatively, 180-degree LAF has been alleged to reduce troublesome dysphagia and gas-related symptoms, with similar reflux control. MEDLINE, EMBASE, Cochrane Library, and web of Knowledge CPCI-S were searched for randomized clinical trials comparing primary 180-degree LAF with LNF. The methodological quality was evaluated to assess bias risk. Primary outcomes were esophageal acid exposure, esophagitis, heartburn score, dilatation for dysphagia, modified Dakkak dysphagia score (0-45), and reoperation rate. Meta-analysis was conducted at 1 and 5 years. Five distinct randomized clinical trials comparing 180-degree LAF (n = 227) with LNF (n = 231) were identified. At 1 year, the Dakkak dysphagia score [2.8 vs 4.8; weighted mean difference: -2.25; 95% confidence interval (CI): -2.66 to -1.83; P < 0.001], gas bloating [11% vs 18%; relative risk (RR) 0.59; 95% CI: 0.36-0.97; P = 0.04], flatulence (14% vs 25%; RR: 0.57; 95% CI: 0.35-0.91; P = 0.02), inability to belch (19% vs 31%; RR: 0.63; 95% CI: 0.40-0.99; P = 0.05), and inability to relieve bloating (34% vs 44%; RR: 0.74; 95% CI: 0.55-0.99; P = 0.04) were lower after 180-degree LAF. Esophageal acid exposure (standardized mean difference: 0.19; 95% CI: -0.07 to 0.46; P = 0.15), esophagitis (19% vs 13%; RR: 1.42; 95% CI: 0.69-2.91; P = 0.34), heartburn score (standardized mean difference: 1.27; 95% CI:-0.36 to 2.90; P = 0.13), dilatation rate (1.4% vs 2.8%; RR: 0.60; 95% CI: 0.19-1.91; P = 0.39), reoperation rate (5.7% vs 2.8%; RR: 2.08; 95% CI: 0.80-5.41; P = 0.13), perioperative outcome, regurgitation, proton pump inhibitor (PPI) use, lower esophageal sphincter pressure, and patient satisfaction were similar after 180-degree LAF and LNF. At 5 years, the Dakkak dysphagia score, flatulence, inability to belch, and inability to relieve bloating remained lower after 180-degree LAF. The 5-year heartburn score, dilatation rate, reoperation rate, PPI use, and patient satisfaction were similar. At 1 and 5 years, dysphagia and gas-related symptoms are lower after 180-degree LAF than after LNF, and esophageal acid exposure and esophagitis are similar, with no differences in heartburn scores, patient satisfaction, dilatations, and reoperation rate. These results lend level 1a support for the use of 180-degree LAF for the surgical treatment of gastroesophageal reflux disease.

Objectives: The morbidity associated with revision anterior cruciate ligament reconstruction (ACLR) is largely unknown. The objective of this study was to determine the rate of and risk factors for re-revision, re-operation, and re-admission following revision ACLR in the general population. Methods: All patients who underwent first revision ACLR in Ontario, Canada from January 2004 to December 2010 were identified and followed to December 2012. Exclusions included age (<16 years), previous osteotomy, or multi-ligament knee reconstruction. The main outcome was re-revision ACLR. Secondary outcomes included re-operation [irrigation and debridement (I&D), meniscectomy, manipulation under anesthesia (MUA), contralateral ACLR, and total knee arthroplasty (TKA)], and re-admission within 90 days of surgery. Survival to re-revision was determined using the Kaplan-Meier (KM) approach. A Cox proportional hazards model or logistic regression were used to determine the influence of patient factors (age, sex, neighborhood income quintile, and comorbidity), surgical factors (graft choice, concurrent meniscal procedure, and fixation method), and provider factors (surgeon volume, surgeon years in practice, and hospital status) on outcomes. A post-hoc analysis was performed to determine the influence of the aforementioned factors on overall post-operative infection risk, including both operative and non-operative cases. Results: Overall, 827 patients were included (median age: 30 years; 58.8% males). Single stage revisions comprised 92.9% of cases, and a meniscal procedure (repair or debridement) was performed in 45.3% of cases. The re-revision rate at a mean follow-up of 4.8±2.2 years was 4.4%, and the five-year survival rate was 95.4% (Figure 1). The rates of I&D, meniscectomy, contralateral ACLR, and re-admission were 0.8%, 3.1%, 3.4%, and 4.1%, respectively. MUA and TKA were rare. Young age significantly increased contralateral ACLR risk (risk decreased by 5.1% with each year of age above 16 years, p=0.02), but not re-revision ACLR risk. Low surgeon annual volume of revision ACLR [<4 revisions/year: odds ratio (OR) 1.2, p=0.02)] and male sex (OR 13.3, p=0.01) significantly increased overall infection risk, while male sex also influenced I&D risk. No other factors significantly influenced re-revision, re-operation, or re-admission risk. Conclusion: Re-revision, re-operation, and re-admission rates following revision ACLR are low. The risk of I&D, overall infection, and contralateral ACLR were influenced by male sex, low surgeon volume, and young age, respectively. This is the first study of this magnitude to determine rates of and risk factors for morbidity following revision ACLR, providing clinicians with reference data from the general population.

Idusuyi, O B; Kitaoka, H B; Patzer, G L

1998-06-01

Twenty patients (14 women and 6 men) (23 feet) had a single oblique osteotomy operation of the 2nd, 3rd, or 4th metatarsal without fixation during an 8-year period. The mean age was 46 years (range, 21-64 years). Each patient had a painful intractable plantar keratosis preoperatively. The average follow-up was 10 years (range, 3-14 years). Postoperatively, reoperation was performed in four feet because of painful callosities. For 13 of the 19 feet that did not have reoperation, patients were limited in footwear or required a shoe insert. Overall results were good for 10 feet, fair for 7 feet, and poor for 6 feet. The only complication was a deep infection that occurred in one foot (good result). Nonunion occurred in one foot and delayed union in one. The average decrease in metatarsal length after osteotomy was 6+/-6 mm. The single oblique lesser metatarsal osteotomy may be successful, but one half of the patients continued to have some degree of pain and most patients had limitations in footwear. Overall results were disappointing, and patients who are offered this procedure should be advised of its limitations.

Long-term Outcomes of Mitral Valve Repair Versus Replacement for Degenerative Disease: A Systematic Review

PubMed Central

McNeely, Christian A; Vassileva, Christina M

2015-01-01

The short-term advantage of mitral valve repair versus replacement for degenerative disease has been extensively documented. These advantages include lower operative mortality, improved survival, better preservation of left-ventricular function, shorter post-operative hospital stay, lower total costs, and fewer valve-related complications, including thromboembolism, anticoagulation-related bleeding events and late prosthetic dysfunction. More recent written data are available indicating the long-term advantage of repair versus replacement. While at some institutions, the repair rate for degenerative disease may exceed 90%, the national average in 2007 was only 69%. Making direct comparisons between mitral valve repair and replacement using the available studies does present some challenges however, as there are often differences in baseline characteristics between patient groups as well as other dissimilarities between studies. The purpose of this review is to systematically summarize the long-term survival and reoperation data of mitral valve repair versus replacement for degenerative disease. A PubMed search was done and resulted in 12 studies that met our study criteria for comparing mitral valve repair versus replacement for degenerative disease. A systematic review was then conducted abstracting survival and reoperation data. PMID:25158683

To evaluate the effect of adjunctive subtenon injection of triamcinolone acetonide (TA) in gas-filled eyes after vitrectomy for complicated proliferative diabetic retinopathy (PDR). This nonrandomized comparative study included 27 patients (27 eyes) who underwent pars plana vitrectomy and gas tamponade for treatment of PDR with tractional or combined tractional-rhegmatogenous retinal detachment and who received subtenon injection of TA (40 mg) at the end of surgery. The study group was compared with the control group (29 eyes), which was matched with the study group for preoperative and intraoperative parameters, but underwent pars plana vitrectomy and gas tamponade without a subtenon injection of TA. Retinal reattachments without reoperation were achieved in 25 eyes (92.6%) and 26 eyes (89.7%) at 6 months (p = 1.000) in the study and control groups, respectively. The study group and the control group did not differ significantly in the frequency of postoperative proliferative vitreoretinopathy, retinal redetachment rate, reoperation rate, macular pucker formation, postoperative vitreous hemorrhage, gain in visual acuity, intraocular pressure, and intraocular inflammation (p > 0.05). The clinical results of pars plana vitrectomy for complicated PDR are not improved significantly by an adjunctive subtenon TA injection in gas-filled eyes.

Left thoracotomy is infrequently used for cardiac procedures, but its application in reoperative and minimally invasive coronary revascularization and in valvular procedures has been reported recently. Three case reports and a review of the current literature illustrate the unique benefits of this approach for myocardial revascularization and valve replacement. Reoperative coronary revascularization of the left anterior descending and circumflex coronary arteries was performed off-pump via a left posterolateral thoracotomy. For the second case, this approach was used for coronary artery bypass grafting of the right coronary and left anterior descending arteries with femoral-femoral cardiopulmonary bypass in a patient with congestive heart failure and coronary artery disease who also required closure of a patent ductus arteriosus. In the third case, mitral valve replacement using femoral venous and aortic cannulation for cardiopulmonary bypass was performed via a left thoracotomy to avoid a retrosternal gastric conduit in a patient with severe mitral stenosis and congestive heart failure. All patients returned to normal activity and are asymptomatic. These case reports and a comprehensive review of the literature demonstrate the utility of left thoracotomy as an alternative approach to standard median sternotomy in selected cases of revascularization and valvular procedures.

From August 1971 through November 1972, we implanted 62 Model 2 DeBakey-Surgitool aortic valve prostheses in 62 patients, 4 of whom later had clinically asymptomatic strut fractures. In 1 case, the patient died suddenly, and autopsy revealed detachment of the ball-cage; in each of the other 3 cases, fractures of 2 struts close to the base of the prosthesis were diagnosed fluoroscopically, and the patients underwent successful reoperation. The interval between implantation and reoperation ranged from 11 months to 16 years, 9 months. In 1 patient, retrospective study of chest radiographs revealed that the fracture had been present for 2(1/2) years. Larger valves (>/= A6) were affected significantly more often than smaller ones. We performed metallurgic analysis of 1 prosthesis: results revealed strut wear from fatigue cracking and secondary abrasion. Strut fracture was also promoted by suspension of the cage at right angles to the prosthetic ring and by use of a pyrolytic carbon ball in a titanium cage (i.e., an occluder harder than its holder). Patients with DeBakey-Surgitool aortic valve prostheses should undergo annual radiologic examinations to enable early detection of strut fractures. Prophylactic valve replacement is not indicated.

Abstract Background: This meta-analysis aims to evaluate the efficacy and safety of hip arthroscopy versus open surgical dislocation for treating femoroacetabular impingement (FAI) through published clinical trials. Methods: We conducted a comprehensive literature search using PUBMED, EMBASE, and the Cochrane Central Register of Controlled Trials databases for relevant studies on hip arthroscopy and open surgical dislocation as treatment options for FAI. Results: Compared with open surgical dislocation, hip arthroscopy resulted in significantly higher Nonarthritic Hip Scores (NAHS) at 3- and 12-month follow-ups, a significant improvement in NAHS from preoperation to 3 months postoperation, and a significantly lower reoperation rate. Open surgical dislocation resulted in a significantly improved alpha angle by the Dunn view in patients with cam osteoplasty from preoperation to postoperation, compared with hip arthroscopy. This meta-analysis demonstrated no significant differences in the modified Harris Hip Score, Hip Outcome Score-Activities of Daily Living, or Hip Outcome Score-Sport Specific Subscale at 12 months of follow-up, or in complications (including nerve damage, wound infection, and wound dehiscence). Conclusion: Hip arthroscopy resulted in higher NAHS and lower reoperation rates, but had less improvement in alpha angle in patients with cam osteoplasty, than open surgical dislocation.

The continuing controversy between proponents of open and closed commissurotomy might be clarified by analysis of late follow-up with modern actuarial techniques that provide a true perspective of patient risk. We have used open mitral commissurotomy exclusively for 15 years in 100 patients. There was one operative death from pancreatitis and one late death from cancer; the actuarially projected survival rate (+/- the standard error) at 10 years is 97 per cent (+/- 2). Thirteen patients had preoperative emboli, 6 of whom were in sinus rhythm and 7 in atrial fibrillation. Two patients had postoperative emboli, both in sinus rhythm. The actuarial chance of remaining free of embolism at 10 years is 97 per cent (+/- 2). Sixteen patients required reoperation on the mitral valve for functional deterioration. The remaining survivors were in Class I or II when last seen. The actuarial chance of not requiring a reoperation after 5 years is 91 per cent (+/- 4) and at 10 years, 38 per cent(+/- 16). Results in different centers are difficult to compare for many reasons, but imprecise statistical methods further obscure such comparisons. The use of actuarial techniques may help to define the role of open mitral commissurotomy.

Reverse-Muscle Sling Reduces Complications in Revisional Mastopexy-Augmentation.

Simultaneous augmentation-mastopexy is a particularly tricky operation with a considerable reoperation rate. The pectoralis muscle sling has proven to be a suitable alternative technique for long-term results in breast parenchyma suspension without silicone implants. This study aims to propose a promising approach to simultaneous augmentation-mastopexy revisional surgery using an inverted dual-plane technique acting as a muscular sling. A 10-year historic cohort was conducted to obtain the following variables from our preexisting database: age, preoperative measurements, operative technicalities, implant details, time from procedure to revision, complications, and outcomes. Twenty-six patients assessed after the initial postoperative year were analyzed. Review of this series of patients revealed a revision rate of 3.8% and overall rate of morbidity of 11.5%. Simultaneous augmentation-mastopexy using an inverted dual-plane technique acting as a muscular sling is a reliable and safe procedure. Review of this series of patients revealed low rates of morbidity and reoperation need. This journal requires that authors assign a level of evidence to each article.

Editorial Commentary: Graft Removal Versus Retention for Septic Arthritis After Anterior Cruciate Ligament Reconstruction: Accounting for Patient Preference Flips the Script on Current Practice.

PubMed

Cote, Mark P

2018-03-01

Septic arthritis is a rare but potentially devastating complication after anterior cruciate ligament (ACL) reconstruction. Studies examining surgical treatment options including graft retention and removal are largely inconclusive. Although the literature indicated that 43.8% of patients who have the graft removed later go on to have a revision ACL reconstruction compared with only 6.5% among those whose graft is retained, this expected-value decision analysis found removal to be the optimal treatment for patients with septic arthritis after ACL reconstruction. This is largely based on patient preference to avoid a late reoperation for residual knee infection. These findings support the concept of utility when considering treatment options for patients with a septic knee. For some, avoiding a late reoperation for a persistent infection is the most important factor and as such graft removal may be the most appropriate treatment to produce a positive outcome among these patients despite the fact that currently, an attempt at graft retention could represent the generally preferred treatment option among practicing surgeons.

Fluid lavage of open wounds (FLOW): design and rationale for a large, multicenter collaborative 2 x 3 factorial trial of irrigating pressures and solutions in patients with open fractures.

PubMed

2010-05-06

Open fractures frequently result in serious complications for patients, including infections, wound healing problems, and failure of fracture healing, many of which necessitate subsequent operations. One of the most important steps in the initial management of open fractures is a thorough wound irrigation and debridement to remove any contaminants. There is, however, currently no consensus regarding the optimal approach to irrigating open fracture wounds during the initial operative procedure. The selection of both the type of irrigating fluid and the pressure of fluid delivery remain controversial. The primary objective of this study is to investigate the effects of irrigation solutions (soap vs. normal saline) and pressure (low vs. high; gravity flow vs. high; low vs. gravity flow) on re-operation within one year among patients with open fractures. The FLOW study is a multi-center, randomized controlled trial using a 2 x 3 factorial design. Surgeons at clinical sites in North America, Europe, Australia, and Asia will recruit 2 280 patients who will be centrally randomized into one of the 6 treatment arms (soap + low pressure; soap + gravity flow pressure; soap + high pressure; saline + low pressure; saline + gravity flow pressure; saline + high pressure). The primary outcome of the study is re-operation to promote wound or bone healing, or to treat an infection. This composite endpoint of re-operation includes a narrow spectrum of patient-important procedures: irrigation and debridement for infected wound, revision and closure for wound dehiscence, wound coverage procedures for infected or necrotic wound, bone grafts or implant exchange procedures for established nonunion in patients with postoperative fracture gaps less than 1 cm, intramedullary nail dynamizations in the operating room, and fasciotomies for compartment syndrome. Patients, outcome adjudicators, and data analysts will be blinded. We will compare rates of re-operation at 12 months across soap vs. saline, low pressure vs. high pressure, gravity flow pressure vs. high pressure, and low pressure vs. gravity flow pressure. We will measure function and quality of life with the Short Form-12 (SF-12) and the EuroQol-5 Dimensions (EQ-5D) at baseline, 2 weeks, 6 weeks, 3 months, 6 months, 9 months, and 12 months after initial surgical management, and measure patients' illness beliefs with the Somatic Pre-Occupation and Coping (SPOC) questionnaire at 1 and 6 weeks. We will also compare non-operatively managed infections, wound healing, and fracture healing problems at 12 months after initial surgery. This study represents a major international effort to identify a simple and easily applicable strategy for emergency wound management. The importance of the question and the potential to identify a low cost treatment strategy argues strongly for global participation, especially in low and middle income countries such as India and China where disability from traumatic injuries is substantial. This trial is registered at ClinicalTrials.gov (NCT00788398).

Wound complications remain a significant source of morbidity for patients undergoing open infra-inguinal re-vascularization. The purpose of this study was to determine the impact of several infection-control strategies on post-operative wound complications after open infra-inguinal re-vascularization. A retrospective cohort study was conducted among all patients who underwent an open infra-inguinal re-vascularization procedure before and after 2014. Since 2014, we have implemented strategies to reduce post-operative wound complications, including: (1) Decreasing the use of incisional skin staples, (2) increasing the use of negative pressure wound therapy (NPWT) dressings, and (3) implementing an outpatient elective decontamination protocol for methicillin-resistant Staphylococcus aureus. "Pre-era" is defined as the period between January 2012 and December 2013, before the implementation of infection control strategies; "Post-era" is between January 2015 and August 2016, after implementation. The primary outcome of interest is 30-day wound complications (infection or dehiscence). Multi-variable logistic regression analysis was used to identify significant predictors of wound-related complications between the two cohorts. Propensity score adjustment controlled for baseline patient characteristics, peri-operative variables, and surgeon experience. A total of 338 open infra-inguinal procedures were performed: 175 in the pre-era and 163 in the post-era. Chlorhexidine skin preparation was used in the majority (321 [95%]) of cases. Comparing the periods, the post-era is characterized by a significant decrease in the use of groin staples (118 [67%] vs. 51 [31%], p < 0.001), and an increased application of NPWT dressings (6 [4%] vs. 66 [43%], p < 0.001). Thirty-five (37%) outpatient elective cases received the pre-operative decontamination protocol in the post-era. Compared with the pre-era, there was a decrease in the 30-day rate of wound complications (68 [39%] to 42 [26%], p = 0.011), and infection-related re-admissions (31 [17.7%] to 21 [12.9%], p = 0.220). When adjusting for patient characteristics, operative variables, and surgeon experience, post-era had significantly lower wound complications (odds ratio [OR] 0.33, p = 0.002) and re-operations (OR 0.16, p = 0.007). Among outpatient elective cases, the decontamination protocol was also independently associated with these two outcomes (wound complications: OR 0.05, p = 0.006; re-operations: 0.06, p = 0.002). The use of groin staples was an independent predictor of deep groin infections (OR 248, p < 0.001) and re-operations (OR 8.16, p = 0.032). Wound complications after open infra-inguinal re-vascularization have decreased significantly after the implementation of several infection-control strategies. Findings suggest that skin staples should be avoided in groin wounds, and anti-staphylococcal decontamination protocols decrease wound complications and prevent re-operations.

Objectives: Hip arthroscopy utilization has significantly increased over the past decade, with annual rates increasing as much as 300-600% in that time period. While large sample data demonstrates significant improvement in clinical outcomes out to two years post-operatively, with low rates of associated post-operative complications, there is little information on the long-term survival of primary hip arthroscopy procedures. The purpose of this study is to report on the rates of revision hip arthroscopy and conversion to resurfacing or total hip arthroplasty (THA) following hip arthroscopy in the State of New York. We will also report on prognostic variables that may contribute to the need for repeat surgery. Methods: The Statewide Planning and Research Cooperative System (SPARCS) database, a census of all hospital admissions and ambulatory surgery in New York State, was used to identify cases of outpatient primary hip arthroscopy. Demographic information was collected for these patients. After case identification, unique identifiers were utilized to identify those patients that underwent revision hip arthroscopy or subsequent ipsilateral hip resurfacing or THA. The risks of each of these outcomes were modeled with use of age, sex, socio-economic status, hospital and surgeon volume as potential risk factors. Patients were also tracked for 30-day and 90-day complications requiring re-admission. Results: We identified 8,267 hip arthroscopy cases from 1998-2012 performed by 295 surgeons in 137 different surgical centers. Demographics revealed that 46.1% of patients were male, with 80.2% carrying private insurance. Annual hip arthroscopy rates increased 88-fold over the observation period, with a 750% increase over the last 10 years. Revision surgery (scope or arthroplasty) was required in 1,087 cases (13.1%) at a mean of 622 ± 603 days. More specifically, revision hip arthroscopy was required in 310 cases (3.8%) at a mean of 649 ± 586 days after the index procedure, while conversion to either resurfacing or THA was required in 796 (9.7%) cases at an average of 616 ± 616 days. The 30-day complication rate, excluding revision surgery, was 0.2%, while the 90-day complication rate was 0.3%. Thirty-day all-cause re-admission rate was 0.7%. Regression analysis revealed that age > 50 y.o. was associated with increased risk of re-operation (Hazard Ratio[HR] 2.30; CI 2.02-2.62), while males carried a slightly lower risk of re-operation (HR 0.88, CI 0.78 -1.0). Additionally, increased surgical volume, for both surgeon and center (≥75th percentile of annual cases), resulted in a lower risk of re-operation (HR 0.64; CI 0.53-0.77; HR 0.61; CI 0.51-0.73). Conclusion: Hip arthroscopy represents a viable treatment option for femoroacetabular impingement, with low rates of revision surgery and conversion to hip arthroplasty. Age less than 50 and higher surgeon and center surgical volume were associated with lower risk of re-operation.

Over the past decade, osteochondral allograft transplantation has soared in popularity. Advances in storage techniques have demonstrated improved chondrocyte viability at longer intervals and allowed for potential of increased graft availability. Recent studies have stratified outcomes according to location and etiology of the chondral or osteochondral defect. Unipolar lesions generally have favorable outcomes with promising 10-year survival rates. Though those undergoing osteochondral allograft transplantation often require reoperation, patient satisfaction remains high.

While some cases of nocardial pneumonia develop secondary empyema, tension pyopneumothorax is a very rare and lethal complication. A 74-year-old man who exhibited thrombocytopenia during steroid therapy for autoimmune hepatitis, presented to our department with a nocardial tension pyopneumothorax. He underwent a left lower lobectomy after chest drainage, and was discharged without any complication other than reoperation to remove a postoperative hematoma.

The role of capital realignment versus in situ stabilization for the treatment of slipped capital femoral epiphysis.

PubMed

Souder, Christopher D; Bomar, James D; Wenger, Dennis R

2014-12-01

Slipped capital femoral epiphysis (SCFE) can be treated by a variety of methods with the traditional method of in situ pin fixation being most commonly used. More recently, the Modified Dunn (Mod. Dunn) procedure consisting of capital realignment has been popularized as a treatment method for SCFE, particularly for more severe cases. Over the last 5 years, our institution has selectively used this method for more complex cases. The purpose of this article is to evaluate the differences between these 2 treatment methods in terms of avascular necrosis (AVN) rate, reoperation rate, and complication rate. Eighty-eight hips that were surgically treated for SCFE between July 2004 and June 2012 met our inclusion criteria. The in situ fixation group included 71 hips, whereas 17 hips were anatomically reduced with the Mod. Dunn procedure. Loder classification, severity, acuity, complication rate, and reoperation rate were determined for the 2 cohorts. The χ analysis was performed to evaluate the relationship between the treatment method and outcome. As expected, stable slips did well with in situ pinning with no cases of AVN, even in more severe slips. Ten stable slips were treated with the Mod. Dunn approach and 2 (20%) developed AVN. Unstable slips were more difficult to treat with 3 of the 7 hips stabilized in situ developing AVN (43%). Two of the 7 unstable slips treated by the Mod. Dunn procedure developed AVN (29%). The other outcomes studied (reoperation rate and complication rate) were not significantly related to the surgical treatment method (P = 0.732 and 0.261, respectively). In situ pinning remains a safe and predictable method for treatment of stable SCFE with no AVN noted, even in severe slips. Attempts to anatomically reduce stable slips led to severe AVN in 20% of cases, thus this treatment approach should be considered with caution. Treatment of unstable slips remains problematic with high AVN rates noted whether treated by in situ fixation or capital realignment (Mod. Dunn). Level III retrospective comparative study.

Transanal decompression tube (TDT), an alternative intervention believed to have potential equivalent efficacy in reducing anastomotic leakage after rectal cancer surgery and lower complication rates compared to protective stoma, was sporadically applied in some medical centers during recent decade. The objective of this meta-analysis was to evaluate the effect of the TDT in preventing the anastomotic leakage after low anterior resection for rectal cancer. The studies comparing TDT and non-TDT in rectal cancer were researched up to March 22, 2016 without language preference, in databases of PubMed, Web of Science, Cochrane library, International Clinical Trials Registry Platform, and National Clinical Trials Registry. The rates of anastomotic leakage, bleeding, and re-operation were separately calculated and compared between TDT and non-TDT groups using RevMan 5.3. Funnel plots, and Egger's tests were used to evaluate the publication biases of the studies. Two prospective randomized controlled trial studies and five observational cohort studies with 833 participants in TDT group and 939 participants in non-TDT group were finally included in this meta-analysis. The results indicated that the TDT group had lower anastomotic leakage rate than non-TDT group with significant RR (RR 0.44; 95 % CI 0.29-0.66; P < 0.0001) and heterogeneity (I 2  = 33 %; P = 0.18). So did the re-operation rate, with RR (RR 0.16; 95 % CI 0.07-0.37; P < 0.0001) and heterogeneity among the studies (I 2  = 0 %; P = 0.80). There was no significant difference in anastomotic bleeding rates (RR 1.48; 95 % CI 0.79-2.77; P = 0.22) (I 2  = 58 %; P = 0.09). No publication bias was found by Egger's test (anastomotic leakage rate, Pr > |z| = 0.224; re-operation rate, Pr > |z| = 0.425). TDT might be an efficient and economic intervention in preventing anastomotic leakage after rectal cancer surgery.

The authors have established a multicenter registry to assess the efficacy and costs of common lumbar spinal procedures using prospectively collected outcomes. Collection of these data requires an extensive commitment of resources from each site. The aim of this study was to determine whether outcomes data from shorter-interval follow-up could be used to accurately estimate long-term outcome following lumbar discectomy. An observational prospective cohort study was completed at 13 academic and community sites. Patients undergoing single-level lumbar discectomy for treatment of disc herniation were included. SF-36 and Oswestry Disability Index (ODI) data were obtained preoperatively and at 1, 3, 6, and 12 months postoperatively. Quality-adjusted life year (QALY) data were calculated using SF-6D utility scores. Correlations among outcomes at each follow-up time point were tested using the Spearman rank correlation test. One hundred forty-eight patients were enrolled over 1 year. Their mean age was 46 years (49% female). Eleven patients (7.4%) required a reoperation by 1 year postoperatively. The overall 1-year follow-up rate was 80.4%. Lumbar discectomy was associated with significant improvements in ODI and SF-36 scores (p < 0.0001) and with a gain of 0.246 QALYs over the 1-year study period. The greatest gain occurred between baseline and 3-month follow-up and was significantly greater than improvements obtained between 3 and 6 months or 6 months and 1 year(p < 0.001). Correlations between 3-month, 6-month, and 1-year outcomes were similar, suggesting that 3-month data may be used to accurately estimate 1-year outcomes for patients who do not require a reoperation. Patients who underwent reoperation had worse outcomes scores and nonsignificant correlations at all time points. This national spine registry demonstrated successful collection of high-quality outcomes data for spinal procedures in actual practice. Three-month outcome data may be used to accurately estimate outcome at future time points and may lower costs associated with registry data collection. This registry effort provides a practical foundation for the acquisition of outcome data following lumbar discectomy.

Laparoscopic techniques can be used to treat patients whose antireflux surgery has failed. Case series. Two academic medical centers. Forty-six consecutive patients, of whom 21 were male and 25 were female (mean age, 55.6 years; range, 15-80 years). Previous antireflux procedures were laparoscopic (21 patients), laparotomy (21 patients), thoracotomy (3 patients), and thoracoscopy (1 patient). The cause of failure, operative and postoperative morbidity, and the level of follow-up satisfaction were determined for all patients. The causes of failure were hiatal herniation (31 patients [67%]), fundoplication breakdown (20 patients [43%]), fundoplication slippage (9 patients [20%]), tight fundoplication (5 patients [11%]), misdiagnosed achalasia (2 patients [4%]), and displaced Angelchik prosthesis (2 patients [4%]). Twenty-two patients (48%) had more than 1 cause. Laparoscopic reoperative procedures were Nissen fundoplication (n = 22), Toupet fundoplication (n = 13), paraesophageal hernia repair (n = 4), Dor procedure (n = 2), Angelchik prosthesis removal (n = 2), Heller myotomy (n = 2), and the takedown of a wrap (n = 1). In addition, 18 patients required crural repair and 13 required paraesophageal hernia repair. The mean +/- SEM duration of surgery was 3.5+/-1.1 hours. Operative complications were fundus tear (n = 8), significant bleeding (n = 4), bougie perforation (n = 1), small bowel enterotomy (n = 1), and tension pneumothorax (n = 1). The conversion rate (from laparoscopic to an open procedure) was 20% overall (9 patients) but 0% in the last 10 patients. Mortality was 0%. The mean +/- SEM hospital stay was 2.3+/-0.9 days for operations completed laparoscopically. Follow-up was possible in 35 patients (76%) at 17.2+/-11.8 months. The well-being score (1 best; 10, worst) was 8.6+/-2.1 before and 2.9+/-2.4 after surgery (P<.001). Thirty-one (89%) of 35 patients were satisfied with their decision to have reoperation. Antireflux surgery failures are most commonly associated with hiatal herniation, followed by the breakdown of the fundoplication. The laparoscopic approach may be used successfully to treat patients with failed antireflux operations. Good results were achieved despite the technical difficulty of the procedures.

In treatment of unstable trochanteric fractures dynamic hip screw and Medoff sliding plate devices are designed to allow secondary fracture impaction, whereas intramedullary nails aim to maintain fracture alignment. Different treatment protocols are used by two similar Swedish regional emergency care hospitals. Dynamic hip screw is used for fractures considered as stable within the respective treatment protocol, whereas one treatment protocol (Medoff sliding plate/dynamic hip screw) uses biaxial Medoff sliding plate for unstable pertrochanteric fractures and uniaxial Medoff sliding plate for subtrochanteric fractures, the second (intramedullary nail/dynamic hip screw) uses intramedullary nail for subtrochanteric fractures and for pertrochanteric fractures with intertrochanteric comminution or subtrochanteric extension. All orthopedic surgeries are registered in a regional database. All consecutive trochanteric fracture operations during 2011-2012 (n = 856) and subsequent technical reoperations (n = 40) were derived from the database. Reoperations were analysed and classified into the categories adjustment (percutaneous removal of the locking screw of the Medoff sliding plate or the intramedullary nail, followed by fracture healing) or minor, intermediate (reosteosynthesis) or major (hip joint replacement, Girdlestone or persistent nonunion) technical complications. The relative risk of intermediate or major technical complications was 4.2 (1.2-14) times higher in unstable pertrochanteric fractures and 4.6 (1.1-19) times higher in subtrochanteric fractures with treatment protocol: intramedullary nail/dynamic hip screw, compared to treatment protocol: Medoff sliding plate/dynamic hip screw. Overall rates of intermediate and major technical complications in unstable pertrochanteric and subtrochanteric fractures were with biaxial Medoff sliding plate 0.68%, with uniaxial Medoff sliding plate 1.4%, with dynamic hip screw 3.4% and with intramedullary nail 7.2%. The treatment protocol based on use of biaxial Medoff sliding plate for unstable pertrochanteric and uniaxial Medoff sliding plate for subtrochanteric fractures reduced the risk of severe technical complications compared to using the treatment protocol based on dynamic hip screw and intramedullary nail.

A primary measure of the success of a procedure is the whether or not additional surgery may be necessary. Multi-institutional studies regarding the need for reoperation after bariatric surgery are scarce. The purpose of this study is to evaluate the rate of revisions/conversions (RC) after 3 common bariatric procedures over 10 years in the state of New York. University Hospital, involving a large database in New York State. The Statewide Planning and Research Cooperative System database was used to identify all patients undergoing laparoscopic adjustable gastric banding (LAGB), sleeve gastrectomy (SG), and Roux-en-Y gastric bypass (RYGB) between 2004 and 2010. Patients were followed for RC to other bariatric procedures for at least 4 years (up to 2014). Multivariable cox proportional hazard regression analysis was performed to identify risk factors for additional surgery after each common bariatric procedure. Multivariable logistic regression was used to check the factors associated with having ≥2 follow-up procedures. There were 40,994 bariatric procedures with 16,444 LAGB, 22,769 RYGB, and 1781 SG. Rate of RC was 26.0% for LAGB, 9.8% for SG, and 4.9% for RYGB. Multiple RC ( = />2) were more common for LAGB (5.7% for LAGB, .5% for RYGB, and .2% for LSG). Band revision/replacements required further procedures compared with patients who underwent conversion to RYGB/SG (939 compared with 48 procedures). Majority of RC were not performed at initial institution (68.2% of LAGB patients, 75.9% for RYGB, 63.7% of SG). Risk factors for multiple procedures included surgery type, as LAGB was more likely to have multiple RC. Reoperation was common for LAGB, but less common for RYGB (4.9%) and SG (9.8%). RC rate are almost twice after SG than after RYGB. LAGB had the highest rate (5.7%) of multiple reoperations. Conversion was the procedure of choice after a failed LAGB.

This study aims to compare mid-long-term clinical outcomes between patients younger than 60 years of age undergoing bioprosthetic and mechanical aortic valve replacement. From January 2002 to December 2009, patients younger than 60 years of age who received Medtronic Hancock II porcine bioprostheses were selected and compared with those who received mechanical bi-leaflet valves in the aortic position. A stepwise logistic regression propensity score identified a subset of 112 evenly matched patient-pairs. Mid-long-term outcomes of survival, valve-related reoperations, thromboembolic events and bleeding events were assessed. The follow-up was only 95.1% complete. Fourteen measurable variables were statistically similar for the matched cohort. Postoperative in-hospital mortality was 3.6% (bioprosthetic valves) and 2.7% (mechanical valves) (P = 0.700). Survival at 5 and 10 years was 96.3 and 88.7% for patients receiving bioprosthetic valve replacement versus 96.3 and 87.9% for patients receiving mechanical valve replacement (P = 0.860), respectively. At 5 and 10 years after operations, freedom from valve-related reoperation was 97.2 and 94.8% for patients receiving mechanical valve replacement, and 96.3 and 90.2% for patients receiving bioprosthetic valve replacement (P = 0.296), respectively. There was no difference between freedom from thromboembolic events (P = 0.528) and bleeding events (P = 0.128) between the matched groups during the postoperative 10 years. In patients younger than 60 years of age undergoing aortic valve replacement, mid-long-term survival rate was similar for patients receiving bioprosthetic versus mechanical valve replacement. Bioprosthetic valves were associated with a trend for a lower risk of anticoagulation treatment and did not have significantly greater likelihood of a reoperation. These findings suggest that a bioprosthetic valve may be a reasonable choice for AVR in patients younger than 60 years of age. © The Author 2015.

Background The mainstay of treatment for craniofacial fibrous dysplasia is surgical; however, optimal indications and techniques are poorly understood, particularly in polyostotic disease and McCune-Albright syndrome. This study investigated surgical indications and risk factors for recurrence in a large cohort. Methods One hundred thirty-three craniofacial fibrous dysplasia subjects in a natural history study were evaluated. Radiographic studies, operative reports, and clinical records were reviewed. Results Thirty-six subjects underwent 103 craniofacial procedures (mean, 2.8 operations per subject), with 13.5 ± 10.5-year follow-up (range, 0 to 39 years). The most common indication was craniofacial deformity (n = 61 operations), including 36 initial operations (59 percent) and 26 reoperations (41 percent). Mean time to reoperation was 3.4 ± 3.2 years (range, 0.3 to 13.3 years). Re-growth occurred after 42 operations (68 percent), and was more frequent after operations in subjects with McCune-Albright syndrome growth hormone excess [22 of 25 operations (88 percent)] than without growth hormone excess [15 of 36 operations (58 percent); p = 0.02]. Of 11 subjects with growth hormone excess, nine (82 percent) were undiagnosed at the time of their initial operation. Regrowth was more frequent after debulking procedures [31 of 38 (82 percent)] than after more aggressive reconstructions [nine of 20 (45 percent); p = 0.007]. Eleven subjects underwent treatment for aneurysmal bone cysts, with recurrence in one subject. Eleven subjects underwent biopsies and none had complications or regrowth. Conclusions Craniofacial fibrous dysplasia regrowth and reoperation are common, particularly after debulking procedures. Outcomes are favorable for aneurysmal bone cysts and biopsies. McCune-Albright syndrome growth hormone excess is a risk factor for regrowth, and may be underdiagnosed in surgical patients. Surgeons should be aware of appropriate screening for endocrinopathies in fibrous dysplasia. These findings highlight the importance of a multidisciplinary approach to craniofacial fibrous dysplasia, and individualized care with long-term follow-up.

Recurrent symptoms of sciatica after previous surgical intervention is a relatively common and troublesome clinical problem. Percutaneous endoscopic lumbar decompression has been proved to be an effective method for recurrent lumbar disc herniation. However, the prognostic factors and outcomes of percutaneous endoscopic lumbar reoperation (PELR) for recurrent sciatica symptoms were still unknown. The purpose of this study was to evaluate the outcomes and prognostic factors of patients who underwent PELR for recurrent sciatica symptoms. From 2009 to 2015, 94 patients who underwent PELR for recurrent sciatica symptoms were enrolled. The primary surgeries include transforaminal lumbar interbody fusion (n = 16), microendoscopic discectomy (n = 31), percutaneous endoscopic lumbar decompression (PELD, n = 17), and open discectomy (n = 30). The mean follow-up period was 36 months, and 86 (91.5%) patients had obtained at least 24 months' follow-up. Of the 94 patients with adequate follow-up, 51 (54.3%) exhibited excellent improvement, 23 (24.5%) had good improvement, and 7 (7.4%) had fair improvement according to modified Macnab criteria. The average re-recurrence rate was 9.6%, with no difference among the different primary surgery groups (PELD, 3/17; microendoscopic discectomy, 2/31; open discectomy, 3/30; transforaminal lumbar interbody fusion, 1/16). There was a trend toward greater rates of symptom recurrence in the primary group of PELD who underwent percutaneous endoscopic lumbar reoperation compared with other groups, but this did not reach statistical significance (P > 0.05). Multivariate analysis suggested that age, body mass index, and surgeon level was independent prognostic factors. Obesity (hazard ratio 13.98, 95% confidence interval 3.394-57.57; P < 0.001) was the risk factor affecting re-recurrence according to logistic regression analysis. PELR is a safe and effective treatment for recurrent sciatica symptoms regardless of different primary operation type. Obesity, inferior surgeon level, and patient age older than 40 years were associated with a worse prognosis. Obesity was also a strong and independent predictor of re-recurrence sciatica symptoms after percutaneous endoscopic lumbar decompression. Copyright © 2017 Elsevier Inc. All rights reserved.

To compare the recurrence rate and need for reoperation after epiretinal membrane surgery with and without removal of the internal limiting membrane. In this retrospective study, 125 patients operated for epiretinal membrane removal were evaluated, with a minimum 6-month follow-up. Removal of the epiretinal membrane (ERM) was performed in 78 patients, while 47 had removal of the epiretinal membrane associated with internal limiting membrane peeling (ERM + ILM). The mean age in the ERM group was 65.8 years old, ranging from 41 to 80 years old. In the ERM + ILM group, the mean age was 67.2 years old, ranging from 52 to 82 years old. The mean preoperative visual acuity in the ERM group was 20/80p, and in the ERM + ILM group, it was 20/80. The mean postoperative visual acuity in both groups was 20/30. The mean preoperative macular thickness in the ERM group was 467 µm ranging from 281 to 663 µm; in the ERM + ILM group, the preoperative macular thickness was 497 µm, ranging from 172 to 798 µm. After surgery, a reduction in macular thickness was observed in both groups. In the ERM group, the mean macular thickness reduction was 361 ± 101. µm, whereas in the ERM + ILM group, it was 367 ± 75.2 µm. Twenty-two patients presented with a recurrence of epiretinal membrane, of which 16 (20.5%) were from the ERM group and 6 (12.8%) were from the ERM + ILM group (p = 0.39); one patient (2%) was retreated in the ERM + ILM group, whereas 5 patients (6%) where retreated in the ERM group. We postulate that ILM peeling for the treatment of epiretinal membrane is not a relevant factor either for visual recovery or macular thickness reduction, but it may reduce the recurrence and reoperation rate.

The purpose of this report is to assess the mid- and long-term outcomes of right ventricular outflow tract (RVOT) reconstruction for children with persistent truncus arteriosus. Between September 2006 and 2016, 105 patients with persistent truncus arteriosus (PTA) received surgical treatment at Shanghai Children's Medical Center. Direct right ventricle-pulmonary artery anastomosis (pulmonary artery pull-down) was performed in 51 patients; a left auricle or pericardial conduit was inserted between the RVOT and pulmonary artery as a connection in 17 patients; heterograft (bovine jugular vein or Gore-tex) conduits and homograft conduits were used in 30 and 7 cases, respectively, to connect the distal pulmonary and right ventricle outflow tract; and pulmonary valve reconstruction was performed in 38 patients using a Gore-tex monocusp. There were six in-hospital deaths and one delayed death 5 months after operation. After a mean follow-up of 55.8 ± 16.5 months (6-113 months), 19 patients underwent reoperation (3 with pulmonary patch enlargement, 14 with conduit replacement and 2 with aortic valve replacement) 10-89 months after the first operation, with 1 hospital death. The actuarial survival rates were 94.2, 93.3 and 93.3% at 1, 5 and 10 years, respectively. Freedom from reoperation was 98.0, 87.8 and 82.7% at 1, 5 and 10 years, respectively. The follow-up variables included echocardiography, chest radiography, cardiac CT and cardiac function. At the last examination, most of the patients exhibited an improvement of New York Heart Association functional class from III or IV preoperatively to I or II at follow-up. Surgical treatment for PTA has an acceptable survival rate and satisfactory outcomes. Most patients exhibited an improvement in cardiac function during follow-up. Aortic arch deformity, truncal valvular regurgitation and long cardiopulmonary bypass time were regarded as risk factors for hospital mortality. Autologous tissue has a lower reoperation rate and better growth potential than extracardiac conduits. A monocusp valve effectively reduces pulmonary regurgitation in the early postoperative stage.

Tetralogy of Fallot became a correctable malformation on August 31, 1954, and from that data through 1960, 106 patients (ages 4 months-45 years) who underwent open repairs at the University of Minnesota and were discharged, have been followed (99% complete) until death or for 26-31 years (mean: 23.7 years, 2424 patient years). The purposes of this study were to determine survival, morbidity, hemodynamics, educational/employment attainments, and relation of these to surgical technics. Operations were done by cross circulation (6 patients) and bubble oxygenator (100 patients). This group had the first uses of patch ventricular septal defect closure, outflow root, infundibuloplasty, atresia correction, ischemic arrests, and pacemakers among other innovations. Twenty-one (of 105 patients) have died during the followup: eight deaths in the first 10 years, 12 between 10 and 20 years, and 1 greater than 20 years. The causes of death were sudden (5), accidental (4), congestive failure (2), reoperation (2), suicide (2), and other (2). Actuarial survival at 30 years was 77%. Late complications were ten reoperations, five arrhythmias, and one endocarditis. Actuarial freedom from reoperations at 30 years was 91%. Cardiac recatheterizations in 62 patients disclosed only 10 with residual shunts. Peak right ventricular systolic pressures were less than 40 mmHg (34 patients), 41-60 mm (2 patients), 61-70 mm (4 patients), greater than 71 mm (4 patients). Thirty-four patients (32%) completed college, ten of these completed graduate school (5 masters degrees, 2 M.D.'s, 2 Ph.D.'s, 1 lawyer). Fifteen others attended college, and nine received technical school diplomas. Forty patients (18 men, 22 women) had progeny, with 82 (93%) live births and six major cardiac defects (7.3%). In summary, complete repair gave excellent late results in this group cared for very early in the open heart era. Survivors led productive lives without restrictions in education and employment. Many of the deaths/complications that occurred are now easily preventable, which augurs extremely well for this generation. PMID:3767482

Assess the effectiveness of priming the extracorporeal circulation system with albumin-mannitol combined with ultrafiltration during extracorporeal circulation to reduce post-operative bleeding and transfusion requirements in heart surgery, as well as its impact on the fluid balance, coagulation and hematocrit parameters, re-operation for bleeding, ICU, and hospital length of stay. A total of 134 patients scheduled for heart surgery were randomized to receive Ringer's lactate 1,500mL in the priming reservoir (group C), or mannitol 20% 250mL, albumin 20% 150mL and Ringer's lactate 1,100mL combined with ultrafiltration (group T). Bleeding volume, transfusions, fluid balance, coagulation, and hematology parameters were determined until 48h in the post-operative period. There was a reduction of postoperative bleeding in group T, 1,165±789mL vs 992±662mL (P=.17), and red blood cell concentrate transfusions, 694±843mL vs 413±605mL (P=.03). Intra-operative and post-operative fluid balance was significantly less positive in group T, with an overall balance of 2,292±2,152mL vs 5,388±2,834mL (P<.001). There were higher values of hemoglobin and hematocrit, intraoperative (P<.001), on admission to ICU (P=.001), and at 6h (P=.05) in group T, and lower INR at 6h (P=.01) and 24h (P=.02). Re-operation rate and length of stay in ICU were higher in group C, but not statiscally significant. The priming of extracorporeal reservoir with mannitol, albumin, and Ringer's lactate, combined with ultrafiltration, significantly improves intra- and post-operative fluid balance, resulting in a reduction in blood transfusions, with no significant decrease in post-operative bleeding, re-operation bleeding rate, and length of stay in the ICU.

Smith, Evan J; Kuang, Xiangyu; Pandarinath, Rajeev

2017-07-01

Tibial shaft fractures comprise a large portion of operatively treated long bone fractures, and present with the highest rate of open injuries. Intramedullary fixation has become the standard of care for both open and closed injuries. The rates of short term complications and hospital length of stay for open and closed fractures treated with intramedullary fixation is not fully known. Previous series on tibia fractures were performed at high volume centers, and data were not generalizable, further they did not report on length of stay and the impact of preoperative variables on infections, complications and reoperation. We used a large surgical database to compare these outcomes while adjusting for preoperative risk factors. Data were extracted from the ACS-NSQIP database from 2005 to 2014. Cases were identified based on CPT codes for intramedullary fixation and categorized as closed vs open based on ICD9 code. In addition to demographic and case data, primary analysis examined correlation between open and closed fracture status with infection, complications, reoperation and hospital length of stay. Secondary analysis examined preoperative variables including gender, race, age, BMI, and diabetes effect on outcomes. There were 272 cases identified. There were no significant demographic differences between open and closed tibia fracture cases. Open fracture status did not increase the rate of infection, 30day complications, reoperation, or length of stay. The only preoperative factor that correlated with length of stay was age. There was no correlation between BMI, presence of insulin dependent and nondependent diabetes, and any outcome measure. When considering the complication rates for open and closed tibial shaft fractures treated with intramedullary fixation, there is no difference between 30-day complication rate, length of stay, or return to the operating room. Our reported postoperative infection rates were comparable to previous series, adding validity to our results. The heterogeneity of the hospitals included in ACS-NSQIP database allow our data to be generalizable. These methods may underrepresent the true occurrence of infection as operatively treated tibia infections may present late, requiring late revision. Despite limitations, the data reflect on the current burden of managing these once devastating injuries. Copyright © 2017 Elsevier Ltd. All rights reserved.

Objective To determine the relationship of perioperative hyperglycemia and insulin administration on outcomes in elective colon/rectal and bariatric operations. Background There is limited evidence to characterize the impact of perioperative hyperglycemia and insulin on adverse outcomes in patients, with and without diabetes, undergoing general surgical procedures. Methods The Surgical Care and Outcomes Assessment Program is a Washington State quality improvement benchmarking-based initiative. We evaluated the relationship of perioperative hyperglycemia (>180 mg/dL) and insulin administration on mortality, reoperative interventions, and infections for patients undergoing elective colorectal and bariatric surgery at 47 participating hospitals between fourth quarter of 2005 and fourth quarter of 2010. Results Of the 11,633 patients (55.4 ± 15.3 years; 65.7% women) with a serum glucose determination on the day of surgery, postoperative day 1, or postoperative day 2, 29.1% of patients were hyperglycemic. After controlling for clinical factors, those with hyperglycemia had a significantly increased risk of infection [odds ratio (OR) 2.0; 95% confidence interval (CI), 1.63–2.44], reoperative interventions (OR, 1.8; 95% CI, 1.41–2.3), and death (OR, 2.71; 95% CI, 1.72–4.28). Increased risk of poor outcomes was observed both for patients with and without diabetes. Those with hyperglycemia on the day of surgery who received insulin had no significant increase in infections (OR, 1.01; 95% CI, 0.72–1.42), reoperative interventions (OR, 1.29; 95% CI, 0.89–1.89), or deaths (OR, 1.21; 95% CI, 0.61–2.42). A dose-effect relationship was found between the effectiveness of insulin-related glucose control (worst 180–250 mg/dL, best <130 mg/dL) and adverse outcomes. Conclusions Perioperative hyperglycemia was associated with adverse outcomes in general surgery patients with and without diabetes. However, patients with hyperglycemia who received insulin were at no greater risk than those with normal blood glucoses. Perioperative glucose evaluation and insulin administration in patients with hyperglycemia are important quality targets. PMID:23235393

To determine the relationship of perioperative hyperglycemia and insulin administration on outcomes in elective colon/rectal and bariatric operations. There is limited evidence to characterize the impact of perioperative hyperglycemia and insulin on adverse outcomes in patients, with and without diabetes, undergoing general surgical procedures. The Surgical Care and Outcomes Assessment Program is a Washington State quality improvement benchmarking-based initiative. We evaluated the relationship of perioperative hyperglycemia (>180 mg/dL) and insulin administration on mortality, reoperative interventions, and infections for patients undergoing elective colorectal and bariatric surgery at 47 participating hospitals between fourth quarter of 2005 and fourth quarter of 2010.

A dose-effect relationship was found between the effectiveness of insulin-related glucose control (worst 180-250 mg/dL, best <130 mg/dL) and adverse outcomes. Perioperative hyperglycemia was associated with adverse outcomes in general surgery patients with and without diabetes.

To study the determinants of functional tricuspid regurgitation (TR) progression after surgical correction of mitral regurgitation, including the influence of mitral valve (MV) repair (MVr) versus replacement (MVR) for degenerative mitral regurgitation. From January 1995 to January 2006, 747 adults with MV prolapse underwent isolated MVr (n=683) or MVR (n=64; mechanical in 32). The mean age was 60.8 years, and 491 were men (66.0%). Moderate preoperative functional TR was present in 115 (15.4%). The MVR group had a greater likelihood of New York Heart Association class III or IV (75.0% vs 34.4%, P<.001), atrial fibrillation (20.3% vs 8.3%, P=.002), a lower left ventricular ejection fraction (61.0% vs 65.2%, P<.003), and a higher pulmonary artery pressure (50.1 vs 41.2 mm Hg, P=.001). The patients were monitored for a mean of 6.9 years (MVr) or 7.7 years (MVR; P=.075). During late follow-up, no difference was found between the groups in the development of moderately severe or severe TR: 1 to 5 years (3.0% vs 3.3%, P=.91) and >5 years (6.1% vs 6.5%; P=.93). The univariate predictors of severe TR after 5 years were older age (hazard ratio [HR], 1.1; P=.011), female gender (HR, 6.86; P=.005), higher pulmonary artery pressure (HR, 1.05; P=.022), and larger left atrial size (HR, 2.11; P=.035). Two patients (0.26%) who had undergone initial MVr required reoperation for late functional TR. Another 2 patients had had the tricuspid valve addressed concurrent with reoperation for MVr failure. No tricuspid reoperations were required in the MVR group. The risk of TR progression was low after MVr or MVR for MV prolapse. Timely MV surgery before the development of left atrial dilatation or pulmonary hypertension could further decrease the risk of TR progression during follow-up.

Risk Factors for Reoperation and Performance-Based Outcomes After Operative Fixation of Foot Fractures in the Professional Athlete: A Cross-Sport Analysis.

PubMed

Singh, Sameer K; Larkin, Kevin E; Kadakia, Anish R; Hsu, Wellington K

Professional athletes are predisposed to fractures of the foot due to large stresses placed on the lower extremity. These players are concerned with efficiently returning to play at a high level. Return-to-play rates after operative treatment have been previously reported, yet performance outcomes after such treatment are generally unknown in this population. Overall, professional athletes sustaining a foot fracture would return to play at high rates with little impact on postoperative performance or league participation. However, National Football League (NFL) athletes would have a significantly greater decline in performance due to the high-impact nature of the sport. Case series. Level 4. Athletes in the National Basketball League (NBA), NFL, Major League Baseball (MLB), and National Hockey League (NHL) undergoing operative fixation of a foot fracture were identified through a well-established protocol confirmed by multiple sources of the public record. Return-to-play rate and time to return were collected for each sport. League participation and game performance data were collected before and after surgery. Statistical analysis was performed, with significance accepted as P ≤ 0.05. A total of 77 players undergoing 84 procedures met the inclusion criteria. Overall, 98.7% (76/77) of players were able to return to play, with a median time to return across all sports of 137 days. Players returned to preoperative performance levels within 1 season of surgery. Six players (7.8%) sustained refracture requiring reoperation, all of whom were in the NBA. Percentage of games started during the season after primary operative treatment was a predictive factor for reinjury (99% vs 40%, P = 0.001). Athletes returned to play at a high rate after foot fracture fixation, with excellent postoperative performance levels, regardless of sport and fracture location. NBA athletes sustaining fifth metatarsal and navicular fractures are at greater risk of reinjury compared with other athletes. Returning to high levels of athletic participation soon after surgery may predispose athletes to refracture and subsequent reoperation. Players, coaches, and team physicians should be aware of the impact of foot fractures on career performance and longevity to best guide therapy.

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether continuation of administration of preoperative aspirin until the day of coronary artery bypass grafting (CABG) could minimize postoperative mortality, prevalence of postoperative myocardial infarction (MI) with or without influence on postoperative bleeding, packed red blood cell (PRBC) transfusion and reoperation for bleeding. Altogether, 662 papers were found using the reported search, 7 of which represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Seven studies, included in this review, consisted of five meta-analyses and two randomized controlled trials. One meta-analysis, involving 27 533 patients submitted to CABG, showed that the administration of preoperative aspirin decreased postoperative 30-day mortality by 27%. Another meta-analysis, including 1437 patients, showed that preoperative aspirin decreased the incidence of perioperative MI by 44%, the effect being even more pronounced with low-dose aspirin, which reduced the prevalence of perioperative MI by 63%. One RCT showed that preoperative aspirin is associated with reduced long-term hazard of MI or repeated revascularization. Four meta-analyses and two RCTs showed that preoperative aspirin is associated with increased postoperative bleeding, PRBC transfusion and reoperation for bleeding. However, this was not the case with preoperative administration of low-dose aspirin. The results presented in these studies suggest that preoperative aspirin administration in patients undergoing CABG has a significant benefit in reducing the incidence of perioperative MI and 30-day mortality rate, as well as reduced long-term hazard of MI or repeated revascularization. At a higher dose (>100 mg/day), postoperative bleeding, PRBC transfusion and reoperation for bleeding increased. However, with low-dose aspirin (≤100 mg/day), these benefits were not at the expense of increased postoperative bleeding or transfusion. © The Author 2016.

Introduction of endoscopic invasive procedures in the 70th and 80th years leaded to decrease reoperations on biliary tree. latrogenic injury of the biliary tract have increased in incidence in the first decade with the introduction of laparoscopic cholecystectomy. Athough a number of factors have been identified with a high risk of injury (and number of technical steps have been emphasized to avoid these injury, the incidence of the bile duct injury has reached at least double the rate observed with open cholecystectomy. Most patients that sustained a bile duct injury are recognized in the weeks following laparoscopic cholecystectomy. Careful preoperative preparation should include control of sepsis by draining any bile collections or fistulas and complete cholangiography. Long-term results are best achieved in specialized hepatobiliary centers performing biliary reconstruction with a Roux-Y hepaticojejunostomy. Success rates over 90% have been reported from several centres to date with intermediate follow-up. Introduction of an invasive endoscopy. Very dangerous is injury after endoscopic papilotomy. In an article of a review of experiences of the Ist Department of Surgery of General hospital in Prague since 1971 in 1 017 reoperations on biliary tree has been carried out. There were in 311 patients 164 hepato-hepatostomies and 147 hepaticojejunostomies used (Tab. 1). By laparoscopic injuries in the last decade were hilary injuries (Bismuth IV) and hepaticojejunostomy was done in all cases. Died 6%, long-term results are acceptable by injured patients with hepatico-hepaticostomies in 70%, by hepaticojejunostomies in 90%. Reoperated were 10% patients. Remnant patients were dilated endoscopically. Postoperatively morbidity was high, above 26%. In years 1995-2003 were 8 patients with papila injury and inflammation in retroperitoneum operated as a injured duodenum (Tab. 2). Better experiences with treatment of injured biliary tree and papila are in centres interested in hepatobiliary surgery which know anatomy of hilus of the liver and can see wide hepaticojejunostomy. Transfer of drained injured patient to centre is possible.

While frequently prescribed to patients following fixation for spine trauma, the utility of spinal orthoses during the post-operative period is poorly described in the literature. In this study, we calculated rates of reoperation and performed a decision analysis to determine the utility of bracing following pedicle screw fixation for thoracic and lumbar burst fractures. Pubmed was searched for articles published between 2005 and 2015 for terms related to pedicle screw fixation of thoracolumbar fractures. Additionally, a database of neurosurgical patients operated on within the authors institution was also used in the analysis. Incidences of significant adverse events (wound revision for either dehiscence or infection or re-operation for non-union or instability due to hardware failure) were determined. Pooled means and variances of reported parameters were obtained using a random-effects, inverse variance meta-analytic model for observational data. Utilities for surgical outcome and complications were assigned using previously published values. Of the 225 abstracts reviewed, 48 articles were included in the study, yielding a total of 1957 patients. After including patients from the institutional registry, together a total of 2081 patients were included in the final analysis, 1328 of whom were braced. Non-braced patients were older then braced patients, although this only approached significance (p=0.051). Braced patients had significantly lower rates of re-operation for non-union or clinically significant hardware failure (1.3% vs. 1.8%, p<0.001) although the groups had comparable rates of operative wound dehiscence and infection (p=1.000). These two approaches yielded comparable utility scores (p=0.120). Costs between braced and non-braced patients were comparable excluding the cost of the brace (p=0.256); hence, the added cost of the brace suggests that bracing post-operatively is not a cost effective measure. Bracing following operative stabilization of thoracolumbar fracture does not significantly improve stability, nor does it increase wound complications. Moreover, our data suggests that post-operative bracing may not be a cost-effective measure. Copyright © 2017. Published by Elsevier Ltd.

This study aimed to analyze long-term survival and functional outcomes after truncus arteriosus repair in a single institution with more than 40 years of follow-up. Medical records were analyzed retrospectively in 52 patients who underwent the Rastelli procedure for truncus arteriosus repair between 1974 and 2002. Thirty-five patients survived the initial repair. The median age at the initial operation was 2.8 months (range, 0.1-123 months) and the body weight was 3.9 kg (range, 1.6 to 15.0 kg). The median age at follow-up was 23.6 years (range, 12.4 to 44.5 years). The median follow-up duration was 23.4 years (range, 12.3 to 40.7 years). The actuarial survival rate was 97% at 10 years and 93% at both 20 years and 40 years after the initial operation. At follow-up, most patients were in New York Heart Association (NYHA) functional classes I (73%) and II (24%). Thirty-six percent of patients had full-time jobs, 40% were students, and 21% were unemployed. Most patients (97%) had undergone conduit reoperations. Freedom from reoperation for right ventricular (RV) outflow and pulmonary artery (PA) stenosis was 59% at 5 years, 28% at 10 years, and 3% at 20 years after the initial operation. Freedom from catheter interventions for RV outflow and PA stenosis was 59% at 5 years, 47% at 10 years, and 38% at 20 years after the initial operation. Freedom from truncal valve replacement was 88% at 5 years, 85% at 10 years, and 70% at 20 years after the initial operation. In this single-center retrospective study, with long-term follow-up after repair of truncus arteriosus, long-term survival and functional outcomes were acceptable, despite the requirement for reoperation and multiple catheter interventions for RV outflow and PA stenosis in almost all patients, and the frequent requirement for late truncal valve operations. © 2016 The Authors.

1998-10-01

Although intrathoracic leakage is a major complication of oesophagectomy, precise data concerning diagnostic features and results of conservative treatment are lacking. From 1986 to 1994, 409 oesophagectomies with stapled oesophagogastrostomy were performed, including 358 Lewis-Tanner and 51 Sweet procedures. A water-soluble contrast swallow was routinely performed on day 7 or later, before oral intake was begun. All patients except one received conservative non-surgical treatment, including nutritional support and perianastomotic drainage. Leaks were diagnosed in 38 patients (9.3 per cent). The leakage rate was 7.8 per cent after the Lewis-Tanner procedure and 20 per cent after the Sweet procedure (P < 0.01). Eleven patients had no symptoms. Seven of the 27 patients with symptoms had a contrast swallow that was normal, and subsequently developed a confirmed fistula after the onset of oral intake. Five patients had to undergo reoperation. All asymptomatic patients and 18 symptomatic patients recovered. Nine patients died, mainly from multiple organ failure, including three who had reoperation for resection of the gastroplasty. The potential presence of clinically silent fistula and the deleterious role of oral intake still justify routine detection of leakage after oesophageal resection. Conservative treatment results in survival with preservation of the gastroplasty in most patients, unless multiple organ failure occurs.

2008-01-01

Unconstrained tripolar hip implants provide an additional bearing using a mobile polyethylene component between the prosthetic head and the outer metal shell. Such a design increases the effective head diameter and therefore is an attractive option in challenging situations of unstable total hip arthroplasties. We report our experience with 54 patients treated using this dual mobility implant in such situations. We ascertained its ability to restore and maintain stability, and examined component loosening and component failure. At a minimum followup of 2.2 years (mean, 4 years; range, 2.2–6.8 years), one hip had redislocated 2 months postoperatively and was managed successfully without reoperation by closed reduction with no additional dislocation. Two patients required revision of the implant because of dislocation at the inner bearing. Technical errors were responsible for these failures. Three patients had reoperations for deep infections. The postoperative radiographs at latest followup showed very satisfactory osseointegration of the acetabular component because no radiolucent line or osteolysis was reported. Use of this unconstrained tripolar design was successful in restoring and maintaining hip stability. We observed encouraging results at short-term followup regarding potential for loosening or mechanical failures. Level of Evidence: Level IV, therapeutic study.

Laparoscopic adjustable gastric banding (LAGB) is an option for the treatment of severe obesity. Few US studies have reported long-term outcomes. We aimed to present long-term outcomes with LAGB. Retrospective study of patients who underwent LAGB at an academic medical center in the US from 1/2005 to 2/2012. Outcomes included weight loss, complications, re-operations, and LAGB failure. 208 patients underwent LAGB. Mean BMI was 45.4 ± 6.4 kg/m 2 . Mean follow-up was 5.6 (0.5-10.7) years. Complete follow-up was available for 90% at one year (186/207), 80% at five years (136/171), and 71% at ten years (10/14). Percentage of excess weight loss at one, five, and ten years was 29.9, 30, and 16.9, respectively. Forty-eight patients (23.1%) required a reoperation. LAGB failure occurred in 118 (57%) and higher baseline BMI was the only independently associated factor (OR 1.1; 95%CI 1.0-1.1; p = 0.016). LAGB was associated with poor short and long-term weight loss outcomes and a high failure rate. With the increased safety profile and greater efficacy of other surgical techniques, LAGB utilization should be discouraged. Copyright © 2017 Elsevier Inc. All rights reserved.

Background: Biliary complications remain a significant problem following liver transplantation. Several surgical options can be used to deal with a significant size mismatch between the donor and recipient bile ducts during the biliary anastomosis. We compared biliary transposition to recipient biliary ductoplasty in cadaveric liver transplant. Methods: A total of 33 reconstructions were performed from January 1, 2005 to December 31, 2013. In the biliary transposition group (n=23), 5 reconstructions were performed using an internal stent (5 or 8 French pediatric feeding tube), and 18 were performed without. Of the 10 biliary ductoplasties, 2 were performed with a stent. All patients were managed with standard immunosuppression and ursodiol. Follow-up ranged from 2 months to 5 years. Results: No patients in the biliary transposition group required reoperation; 1 patient had an internal stent removed for recurrent unexplained leukocytosis, and 2 patients required endoscopic retrograde cholangiography and stent placement for evidence of stricture. Three anastomotic leaks occurred in the biliary ductoplasty group, and 2 patients in the biliary ductoplasty group required reoperation for biliary complications. Conclusion: Our results indicate that biliary reconstruction can be performed with either biliary transposition or biliary ductoplasty. These techniques are particularly useful when a significant mismatch in diameter exists between the donor and recipient bile ducts. PMID:28331447

Autologous chondrocyte implantation: superior biologic properties of hyaline cartilage repairs.

Henderson, Ian; Lavigne, Patrick; Valenzuela, Herminio; Oakes, Barry

2007-02-01

Information regarding the quality of autologous chondrocyte implantation repair is needed to determine whether the current autologous chondrocyte implantation surgical technology and the subsequent biologic repair processes are capable of reliably forming durable hyaline or hyaline-like cartilage in vivo. We report and analyze the properties and qualities of autologous chondrocyte implantation repairs. We evaluated 66 autologous chondrocyte implantation repairs in 57 patients, 55 of whom had histology, indentometry, and International Cartilage Repair Society repair scoring at reoperation for mechanical symptoms or pain. International Knee Documentation Committee scores were used to address clinical outcome. Maximum stiffness, normalized stiffness, and International Cartilage Repair Society repair scoring were higher for hyaline articular cartilage repairs compared with fibrocartilage, with no difference in clinical outcome. Reoperations revealed 32 macroscopically abnormal repairs (Group B) and 23 knees with normal-looking repairs in which symptoms leading to arthroscopy were accounted for by other joint disorders (Group A). In Group A, 65% of repairs were either hyaline or hyaline-like cartilage compared with 28% in Group B. Autologous chondrocyte repairs composed of fibrocartilage showed more morphologic abnormalities and became symptomatic earlier than hyaline or hyaline-like cartilage repairs. The hyaline articular cartilage repairs had biomechanical properties comparable to surrounding cartilage and superior to those associated with fibrocartilage repairs.

Comparison of Transverse Intraosseous Loop Technique and Pull Out Suture for Reinsertion of the Flexor Digitorum Profundus tendon. A Retrospective Study.

We compared the results of two methods for reinsertion of flexor digitorum profundus tendons retrospectively. In 35 fingers of 29 patients pull-out suture and in 13 fingers of 11 patients transverse intraosseous loop technique was performed with a mean follow-up of 8 and 6 months, respectively. Eleven and nine fingers achieved "excellent" or "good" function according to Strickland and Glogovac at 8 weeks; 20 and ten at the last control in the pull-out and transverse intraosseous loop groups, respectively. The difference at 8 weeks was statistically significant in favour of the transverse intraosseous loop group. Ten patients underwent 12 complications in the pull-out group (four superficial infections; one rerupture, one PIP and one DIP joint contracture, one adhesion, two granulomas, one nail deformity and one carpal tunnel syndrome) and four of them were reoperated (one carpal tunnel release, one teno-arthrolysis and two resections of granuloma). There was no complication and no reoperation in the transverse intraosseous loop group, the difference being statistically significant for the former. In our study the transverse intraosseous loop technique seemed to be a safe alternative with possibly better functional results compared to the pull-out suture.

Potential costs of breast augmentation mammaplasty.

2016-01-01

Augmentation mammaplasty is one of the most common surgical procedures performed by plastic surgeons. The aim of this study was to estimate the cost of the initial procedure and its subsequent complications, as well as project the cost of Food and Drug Administration (FDA)-recommended surveillance imaging. The potential costs to the individual patient and society were calculated. Local plastic surgeons provided billing data for the initial primary silicone augmentation and reoperative procedures. Complication rates used for the cost analysis were obtained from the Allergen Core study on silicone implants. Imaging surveillance costs were considered in the estimations. The average baseline initial cost of silicone augmentation mammaplasty was calculated at $6335. The average total cost of primary breast augmentation over the first decade for an individual patient, including complications requiring reoperation and other ancillary costs, was calculated at $8226. Each decade thereafter cost an additional $1891. Costs may exceed $15,000 over an averaged lifetime, and the recommended implant surveillance could cost an additional $33,750. The potential cost of a breast augmentation, which includes the costs of complications and imaging, is significantly higher than the initial cost of the procedure.

To determine whether the addition of magnetic resonance imaging (MRI) to current patient evaluation by triple assessment would aid tumour localisation within the breast and thus reduce the reoperation rate in women with primary breast tumours who are scheduled for wide local excision (WLE), and to assess whether the addition of MRI would be cost-effective for the UK NHS. A multicentre, randomised controlled, open, parallel group trial with equal randomisation. The main design was supplemented with a qualitative study to assess patients' experiences of the treatment process and care pathway, and involved the development of a non-scheduled standardised interview (NSSI). The study took place at 45 hospitals throughout the UK. Women aged 18 years or over with biopsy-proven primary breast cancer who had undergone triple assessment, were scheduled for WLE, and were capable of providing written informed consent. Patients were randomised to receive MRI or no MR1. Randomisation was performed using minimisation, incorporating a random element. All MRI was performed at 1.5 T or 1.0 T with a dedicated bilateral breast coil. The primary end point of the trial was the reoperation rate. Secondary outcome measures included discrepancies between imaging and histopathology, and the effectiveness of using both procedures; change in clinical management after using MRI; the clinical significance of MRI-only-detected lesions; the rate of interventions; the ipsilateral tumour recurrence rate; patient quality of life (QoL); and cost-effectiveness. From a total of 1623 patients, 816 were randomised to MRI and 807 to no MRI. No differences in reoperation rates were found between the two groups of patients [MRI patients 18.75%, no MRI 19.33%, difference 0.58%, 95% confidence interval (CI) -3.24 to 4.40]. Therefore, the addition of MRI to conventional triple assessment was not found to be statistically significantly associated with a reduced reoperation rate (odds ratio = 0.96, 95% CI 0.75-1.24, p = 0.7691). The best agreement between all imaging modalities and histopathology with regard to tumour size and extent of disease was found in patients over 50 years old with ductal tumours NST and who were node negative. In the imaging arm, mastectomy was found to be pathologically avoidable for 16 (27.6%) out of 58 patients who underwent the procedure. There were no significant differences between the groups regarding the proportion of patients receiving chemotherapy, radiotherapy or additional adjuvant therapies, as well as for local recurrence-free interval rates and QoL. An acceptable NSSI was developed for use in this population of patients. Economic analysis found no difference in outcomes between the two trial arms. The addition of MRI to triple assessment did not result in a reduction in operation rates, and the use of MRI would thus consume extra resource with few or no benefits in terms of cost-effectiveness or HRQoL. However, MRI showed potential to improve tumour localisation, and preoperative biopsy of MRI-only-detected lesions is likely to minimise the incidence of inappropriate mastectomy.

Open tibial shaft fractures are one of the most devastating orthopaedic injuries. Surgical treatment options include reamed or unreamed nailing, plating, Ender nails, Ilizarov fixation, and external fixation. Using a network meta-analysis allows comparison and facilitates pooling of a diverse population of randomized trials across these approaches in ways that a traditional meta-analysis does not. Our aim was to perform a network meta-analysis using evidence from randomized trials on the relative effect of alternative approaches on the risk of unplanned reoperation after open fractures of the tibial diaphysis. Our secondary study endpoints included malunion, deep infection, and superficial infection. A network meta-analysis allows for simultaneous consideration of the relative effectiveness of multiple treatment alternatives. To do this on the subject of surgical treatments for open tibial fractures, we began with systematic searches of databases (including EMBASE and MEDLINE) and performed hand searches of orthopaedic journals, bibliographies, abstracts from orthopaedic conferences, and orthopaedic textbooks, for all relevant material published between 1980 and 2013. Two authors independently screened abstracts and manuscripts and extracted the data, three evaluated the risk of bias in individual studies, and two applied Grading of Recommendation Assessment, Development and Evaluation (GRADE) criteria to bodies of evidence. We included all randomized and quasirandomized trials comparing two (or more) surgical treatment options for open tibial shaft fractures in predominantly (ie, > 80%) adult patients. We calculated pooled estimates for all direct comparisons and conducted a network meta-analysis combining direct and indirect evidence for all 15 comparisons between six stabilization strategies. Fourteen trials published between 1989 and November 2011 met our inclusion criteria; the trials comprised a total of 1279 patients surgically treated for open tibial shaft fractures. Moderate confidence evidence showed that unreamed nailing may reduce the likelihood of reoperation compared with external fixation (network odds ratio [OR], 0.38; 95% CI, 0.23-0.62; p < 0.05), although not necessarily compared with reamed nailing (direct OR, 0.74; 95% CI, 0.45-1.24; p = 0.25). Only low- or very low-quality evidence informed the primary outcome for other treatment comparisons, such as those involving internal plate fixation, Ilizarov external fixation, and Ender nailing. Method ranking based on reoperation data showed that unreamed nailing had the highest probability of being the best treatment, followed by reamed nailing, external fixation, and plate fixation. CIs around pooled estimates of malunion and infection risk were very wide, and therefore no conclusive results could be made based on these data. Current evidence suggests that intramedullary nailing may be superior to other fixation strategies for open tibial shaft fractures. Use of unreamed nails over reamed nails also may be advantageous in the setting of open fractures, but this remains to be confirmed. Unfortunately, these conclusions are based on trials that have had high risk of bias and poor precision. Larger and higher-quality head-to-head randomized controlled trials are required to confirm these conclusions and better inform clinical decision-making. Level I, therapeutic study.

A 60-year-old woman underwent mitral and aortic valve replacement with Carpentier-Edwards supra-annular bioprosthesis in 1986. Six years later rapidly progressing exercise dyspnea and orthopnea made hospital admission necessary. At chest x-ray and cardiac catheter examination one of the wire struts of the mitral bioprosthesis was found completely broken causing cusp prolapse. Surgical findings at reoperation confirmed the diagnosis. No apparent cause of the stent fracture was found.

Fifty-two patients with rectal prolapse have been treated by the silicone rubber band perianal suture technique and satisfactory results have been obtained in 46 (89%). Eleven patients required reoperation to achieve this result. The procedure is a minor one, with little morbidity and no mortality. Provided that faecal impaction can be avoided in patients having this operation a successful outcome, can be expected. It is recommended especially for the frail and elderly with rectal prolapse.

The surgical treatment of distal tibial fractures is challenging and controversial. Recently, locking plate fixation has become popular, but the outcomes of this treatment are mixed with complication rates as high as 50 % in the published literature. There are no reports specifically relating to the financial and resource costs of failed treatment in the literature. Retrospective service analysis of patients who had undergone locking plate fixation of a distal third tibial fracture between 2008 and 2011 with at least 12 months follow-up. Rates of readmission, reoperation, bony union and infection were ascertained. The financial and resource (hospital stay and number of outpatient appointments) implications of failed treatment were calculated. Forty-two patients were identified. There were 31 type A fractures, one type B fracture and 10 type C fractures. Three injuries were open. Twenty patients were treated with minimally invasive percutaneous osteosynthesis (MIPO). The readmission and reoperation rates were 26 % (n = 11) and 19 % (n = 8), respectively. A total of 89 % of readmissions were due to infection. All patients had received appropriate antibiotic regimens. The average costs of successful and failed treatment were £ 5538 and £ 18,335, respectively. The average time to union was 24.5 weeks. The rate of non-union was 21 % (n = 9). The rate of infection was 28 % (n = 12), with all patients with open fracture incurring an infection. Tourniquet time had no effect on the incidence of complications. Smokers were more likely to incur a complication (p < 0.05), and non-union was lower in the MIPO group (p < 0.05). The length and total cost of inpatient care were significantly lower in the MIPO group (p < 0.05). MIPO patients were five times less likely to incur readmission or reoperation. Failed treatment was three times more expensive and four times longer than successful treatment. The study identified a large burden to the service following failure of locking plate treatment of these fractures, but the outcomes were similar to series published in the literature. Readmission rates were high following these injuries, and failed treatment was costly and had a significant impact on hospital resources. The implementation of major trauma networks and centralised subspecialised units should improve quality and value for money.

To determine whether total hip arthroplasty is associated with lower reoperation rates, mortality, and complications, and better function and quality of life than hemiarthroplasty for displaced fractures of the femoral neck in older patients. Systematic review and meta-analysis of randomised trials, quasirandomised trials, and cohort studies. Medline, Embase, Cochrane register of controlled trials, publishers' databases, and manual search of bibliographies. Randomised controlled trials, quasirandomised trials, and cohort studies (retrospective and prospective) comparing hemiarthroplasty with total hip arthroplasty for treating displaced femoral neck fractures in patients aged more than 60 years. Relative risks, risk differences, and mean differences from each trial, aggregated using random effects models. Analyses were stratified for experimental and non-experimental designs, and two way sensitivity analyses and tests for interaction were done to assess the influence of various criteria of methodological quality on pooled estimates. 3821 references were identified. Of the 202 full papers inspected, 15 were included (four randomised controlled trials, three quasirandomised trials, and eight retrospective cohort studies, totalling 1890 patients). Meta-analysis of 14 studies showed a lower risk of reoperation after total hip arthroplasty compared with hemiarthroplasty (relative risk 0.57, 95% confidence interval 0.34 to 0.96, risk difference 4.4%, 95% confidence interval 0.2% to 8.5%), although this effect was mainly driven by investigations without concealed treatment allocation. Total hip arthroplasty consistently showed better ratings in the Harris hip score (three studies, 246 patients, weighted mean difference 5.4, 95% confidence interval 2.7 to 8.2) after follow-up periods of 12 to 48 months. The standardised mean difference of different scores from five studies was 0.42 (95% confidence interval 0.24 to 0.61), indicating a medium functional advantage of total hip arthroplasty over hemiarthroplasty. Total hip arthroplasty was associated with a slightly higher risk of dislocation (relative risk 1.48, 95% confidence interval 0.89 to 2.46) and general complications (1.14, 0.87 to 1.48). Single stage total hip arthroplasty may lead to lower reoperation rates and better functional outcomes compared with hemiarthroplasty in older patients with displaced femoral neck fractures. However, heterogeneity across the available trials and distinct subgroup effects preclude definitive statements and require further research in this area.

OBJECTIVE Existing studies have shown a high overall rate of adverse events (AEs) following pediatric neurosurgical procedures. However, little is known regarding the morbidity of specific procedures or the association with risk factors to help guide quality improvement (QI) initiatives. The goal of this study was to describe the 30-day mortality and AE rates for pediatric neurosurgical procedures by using the American College of Surgeons (ACS) National Surgical Quality Improvement Program-Pediatrics (NSQIP-Peds) database platform. METHODS Data on 9996 pediatric neurosurgical patients were acquired from the 2012-2014 NSQIP-Peds participant user file. Neurosurgical cases were analyzed by the NSQIP-Peds targeted procedure categories, including craniotomy/craniectomy, defect repair, laminectomy, shunts, and implants. The primary outcome measure was 30-day mortality, with secondary outcomes including individual AEs, composite morbidity (all AEs excluding mortality and unplanned reoperation), surgical-site infection, and unplanned reoperation. Univariate analysis was performed between individual AEs and patient characteristics using Fischer's exact test. Associations between individual AEs and continuous variables (duration from admission to operation, work relative value unit, and operation time) were examined using the Student t-test. Patient characteristics and continuous variables associated with any AE by univariate analysis were used to develop category-specific multivariable models through backward stepwise logistic regression. RESULTS The authors analyzed 3383 craniotomy/craniectomy, 242 defect repair, 1811 laminectomy, and 4560 shunt and implant cases and found a composite overall morbidity of 30.2%, 38.8%, 10.2%, and 10.7%, respectively. Unplanned reoperation rates were highest for defect repair (29.8%). The mortality rate ranged from 0.1% to 1.2%. Preoperative ventilator dependence was a significant predictor of any AE for all procedure groups, whereas admission from outside hospital transfer was a significant predictor of any AE for all procedure groups except craniotomy/craniectomy. CONCLUSIONS This analysis of NSQIP-Peds, a large risk-adjusted national data set, confirms low perioperative mortality but high morbidity for pediatric neurosurgical procedures. These data provide a baseline understanding of current expected clinical outcomes for pediatric neurosurgical procedures, identify the need for collecting neurosurgery-specific risk factors and complications, and should support targeted QI programs and clinical management interventions to improve care of children.

The aim of this study was to analyze patient-reported outcomes in those undergoing the triad of simultaneous osteotomy, meniscal transplantation, and articular cartilage repair. Patients undergoing simultaneous meniscal transplantation, distal femoral or proximal tibial osteotomy, and articular cartilage surgery by a single surgeon (B.J.C.) were analyzed. Meniscal transplantation was performed using bone-in-slot techniques. Distal femoral and high tibial osteotomies were performed for valgus and varus malalignment, respectively. Microfracture, autologous chondrocyte implantation, and osteochondral autograft or allograft were performed for articular cartilage disease. Validated patient-reported and surgeon-measured outcomes were collected. Preoperative and postoperative outcomes and medial versus lateral disease were compared using Student t tests. Eighteen participants (mean age, 34 ± 7.8 years; symptomatic patients, 7.4 ± 5.6 years; 2.4 ± 1.0 surgical procedures before study enrollment; mean follow-up, 6.5 ± 3.2 years) were analyzed. Two thirds of participants had medial compartment pathologic conditions and one third had lateral compartment pathologic processes. At final follow-up, there were statistically significant clinically meaningful improvements in International Knee Documentation Committee (IKDC) subjective classification, Lysholm score, and 4 Knee Injury and Osteoarthritis Outcome Score (KOOS) subscores. Postoperative 12-item short form (SF-12) physical and mental component scores were not significantly different from preoperative scores. The Kellgren-Lawrence classification grade was 1.5 ± 1.1 at 2.5 ± 3.0 years after surgery. There was a significantly higher preoperative SF-12 physical composite score (PCS) in participants with lateral compartment pathologic conditions (v medial compartment conditions) (P = .011). Although there were 13 reoperations in 10 patients (55.5% reoperation rate), only one patient was converted to knee arthroplasty (5.6%) and one to revision cartilage surgery and meniscal transplantation (5.6% revision rate). The most common complication was arthrofibrosis (16.7%). Statistically significant and clinically meaningful improvements in validated patient-reported clinical outcome scores at long-term follow-up were observed in 18 participants undergoing combined meniscal transplantation, osteotomy, and articular cartilage surgery. Although there was a low rate of cartilage or meniscal revision (or both) and total knee arthroplasty, there was a high rate of reoperation. There was no significant difference in outcomes between participants with medial versus lateral pathologic conditions. Level IV, therapeutic case series.

Pectoralis major tendon ruptures have become increasingly common injuries among young, active individuals over the past 30 years; however, there is presently a paucity of reported outcome data. We investigated the ability to return to full preoperative level of function, complications, reoperation rates, and risk factors for failure following surgical repair of the pectoralis major tendon in a cohort of young, highly active individuals. All U.S. active-duty military patients undergoing pectoralis major tendon repair between 2008 and 2013 were identified from the Military Health System using the Management Analysis and Reporting Tool (M2). Demographic characteristics, injury characteristics, and trends in preoperative and postoperative self-reported pain scale (0 to 10) and strength were extracted. The ability to return to the full preoperative level of function and rates of rerupture and reoperation were the primary outcome measures. Univariate analysis followed by multivariate analysis identified significant variables. A total of 257 patients with pectoralis major tendon repair were identified with a mean follow-up (and standard deviation) of 47.8 ± 17 months (range, 24 to 90 months). At the time of the latest follow-up, 242 patients (94%) were able to return to the full preoperative level of military function. Fifteen patients (5.8%) were unable to return to duty because of persistent upper-extremity disability. A total of 15 reruptures occurred in 14 patients (5.4%). Increasing body mass index and active psychiatric conditions were significant predictors of inability to return to function (odds ratio, 1.56 [p = 0.0001] for increasing body mass index; and odds ratio, 6.59 [p = 0.00165] for active psychiatric conditions) and total failure (odds ratio, 1.26 [p = 0.0012] for increasing body mass index; and odds ratio, 2.73 [p = 0.0486] for active psychiatric conditions). We demonstrate that 94% of patients were able to return to the full preoperative level of function within active military duty following surgical repair of pectoralis major tendon rupture and 5.4% of patients experienced rerupture after primary repair. Increasing body mass index and active psychiatric diagnoses are significant risk factors for an inability to return to function and postoperative failures. Therapeutic Level IV.

The study aimed to determine the clinical performance of bovine pericardial aldehyde-treated products alone or in combination with aortic leaflets of porcine origin. These included a composite porcine stentless aortic valve attached to a scalloped pericardial tube (BSAV), and valved and non-valved bovine pericardial conduits for use in left-sided heart lesions (BPG). For BSAV grafts, between January 1990 and August 1996, 163 patients (119 males) had their aortic valves replaced by SJM Biocor BASV. Mean age was 37.9 +/- 17.6 years (range: 1 to 76 years). Rheumatic heart disease sequelae (n = 72) and replacement of a prosthetic heart valve (n = 46) were predominant. Preoperative NYHA functional class showed 90 patients (55.2%) in class III and 50 (30.7%) in class IV. BPVC and NVPC grafts were used in 166 patients: acute aortic dissection was the main indication in 52 (31.3%) and chronic in 36 (21/7%). The ascending aorta was involved in 141 patients (84.9%); grafts were seldom used at other sites. In most patients the graft implanted was either a non-valved (n = 79) or a valved (n = 75) pericardial conduit. Twelve patients had a localized lesion and required a patch repair. For BASV grafts, the non-valve-related hospital mortality rate was 4.9%. There were 14.7% non-fatal complications with full recovery of all patients. Mean follow up in 141 patients was 3.0 +/- 1.4 years (range: 1 month to 7.2 years); 14 patients were lost to follow up. Late, non-conduit-related, mortality occurred in seven patients (4.9%). Eight patients underwent reoperation. The current clinical follow up of 127 patients has shown 118 (92.9%) with competent valves and nine (7.0%) with mild stable aortic insufficiency. For BPVC and NVPC grafts, hospital mortality rate was 16.9%, death being related to poor preoperative clinical condition. Postoperative follow up was accomplished in 125 patients; reoperation was necessary in seven patients. Histology showed good tissue preservation up to five years; echocardiography revealed satisfactory findings. No valved conduit had to be reoperated for valve or pericardial tissue wear. Clinical results of left-sided heterologous pericardial grafts have shown excellent performance over time. The BASV (over seven years) and BPVC and NVPC (eight years) have demonstrated superior results as aortic valves alone or in combination with a pericardial conduit.

Repairs of the posterior horn of the lateral meniscus can be technically challenging. In contrast to medial meniscus repairs, the capsule around the posterior segment attachment of the lateral meniscus is quite thin. This study evaluates the clinical results of an arthroscopic all-inside repair technique for unstable, vertical, lateral meniscus tears, using a suture repair placed directly into the popliteus tendon. A retrospective analysis of prospectively collected data from the SANTI database was performed. All patients who had undergone combined ACL reconstruction with lateral meniscus all-inside repair, using sutures placed in the popliteus tendon, between 2011 and 2015, were included. Patients were reviewed clinically at 1 and 2 years' follow-up. At final follow-up, all patients were contacted to identify if they underwent further surgery or had knee pain, locking or effusion. Symptomatic patients were recalled for clinical evaluation by a physician and Magnetic Resonance Imaging of the knee. Operative notes for those undergoing further surgery were reviewed and rates and type of re-operation, including for failed lateral meniscal repair were recorded. Two hundred patients (mean age 28.6 ± 10.2 years) with a mean follow-up of 45.5 ± 12.8 months (range 24.7-75.2) were included. The mean Subjective International Knee Documentation Committee (IKDC) at final follow-up was 85.0 ± 11.3. The post-operative mean side-to-side laxity measured at 1 year was 0.6 ± 1.0 mm. Twenty-six patients underwent re-operation (13%) at a mean follow-up of 14.8 ± 7.8 months. The ACL graft rupture rate was 5.0%. Other causes for re-operation included medial meniscus tear (2.5%), cyclops lesion (1.5%) and septic arthritis (0.5%). The lateral meniscus repair failure rate was 3.5%. No specific complications relating to placement of sutures in the popliteus tendon were identified. Arthroscopic all-inside repair of unstable, vertical, lateral meniscus tears using a suture placed in the popliteus tendon is a safe technique. It is associated with a very low failure rate with no specific complications. Level IV.

Continuous-flow left ventricular assist systems increase the rate of survival among patients with advanced heart failure but are associated with the development of pump thrombosis. We investigated the effects of a new magnetically levitated centrifugal continuous-flow pump that was engineered to avert thrombosis. We randomly assigned patients with advanced heart failure to receive either the new centrifugal continuous-flow pump or a commercially available axial continuous-flow pump. Patients could be enrolled irrespective of the intended goal of pump support (bridge to transplantation or destination therapy). The primary end point was a composite of survival free of disabling stroke (with disabling stroke indicated by a modified Rankin score >3; scores range from 0 to 6, with higher scores indicating more severe disability) or survival free of reoperation to replace or remove the device at 6 months after implantation. The trial was powered for noninferiority testing of the primary end point (noninferiority margin, -10 percentage points). Of 294 patients, 152 were assigned to the centrifugal-flow pump group and 142 to the axial-flow pump group. In the intention-to-treat population, the primary end point occurred in 131 patients (86.2%) in the centrifugal-flow pump group and in 109 (76.8%) in the axial-flow pump group (absolute difference, 9.4 percentage points; 95% lower confidence boundary, -2.1 [P<0.001 for noninferiority]; hazard ratio, 0.55; 95% confidence interval [CI], 0.32 to 0.95 [two-tailed P=0.04 for superiority]). There were no significant between-group differences in the rates of death or disabling stroke, but reoperation for pump malfunction was less frequent in the centrifugal-flow pump group than in the axial-flow pump group (1 [0.7%] vs. 11 [7.7%]; hazard ratio, 0.08; 95% CI, 0.01 to 0.60; P=0.002). Suspected or confirmed pump thrombosis occurred in no patients in the centrifugal-flow pump group and in 14 patients (10.1%) in the axial-flow pump group. Among patients with advanced heart failure, implantation of a fully magnetically levitated centrifugal-flow pump was associated with better outcomes at 6 months than was implantation of an axial-flow pump, primarily because of the lower rate of reoperation for pump malfunction.

In an early analysis of this trial, use of a magnetically levitated centrifugal continuous-flow circulatory pump was found to improve clinical outcomes, as compared with a mechanical-bearing axial continuous-flow pump, at 6 months in patients with advanced heart failure. In a randomized noninferiority and superiority trial, we compared the centrifugal-flow pump with the axial-flow pump in patients with advanced heart failure, irrespective of the intended goal of support (bridge to transplantation or destination therapy). The composite primary end point was survival at 2 years free of disabling stroke (with disabling stroke indicated by a modified Rankin score of >3; scores range from 0 to 6, with higher scores indicating more severe disability) or survival free of reoperation to replace or remove a malfunctioning device. The noninferiority margin for the risk difference (centrifugal-flow pump group minus axial-flow pump group) was -10 percentage points. Of 366 patients, 190 were assigned to the centrifugal-flow pump group and 176 to the axial-flow pump group. In the intention-to-treat population, the primary end point occurred in 151 patients (79.5%) in the centrifugal-flow pump group, as compared with 106 (60.2%) in the axial-flow pump group (absolute difference, 19.2 percentage points; 95% lower confidence boundary, 9.8 percentage points [P<0.001 for noninferiority]; hazard ratio, 0.46; 95% confidence interval [CI], 0.31 to 0.69 [P<0.001 for superiority]). Reoperation for pump malfunction was less frequent in the centrifugal-flow pump group than in the axial-flow pump group (3 patients [1.6%] vs. 30 patients [17.0%]; hazard ratio, 0.08; 95% CI, 0.03 to 0.27; P<0.001). The rates of death and disabling stroke were similar in the two groups, but the overall rate of stroke was lower in the centrifugal-flow pump group than in the axial-flow pump group (10.1% vs. 19.2%; hazard ratio, 0.47; 95% CI, 0.27 to 0.84, P=0.02). In patients with advanced heart failure, a fully magnetically levitated centrifugal-flow pump was superior to a mechanical-bearing axial-flow pump with regard to survival free of disabling stroke or reoperation to replace or remove a malfunctioning device.

Osteochondral allograft transplantation (OCA) is often performed with concomitant meniscus allograft transplantation (MAT) as a strategy for knee joint preservation, although to date, the effect of concomitant MAT on outcomes and failure rates after OCA has not been assessed. To determine clinical outcomes for patients undergoing OCA with MAT as compared with a matched cohort of patients undergoing isolated OCA. Control study; Level of evidence, 3. Patients who underwent OCA of the medial or lateral femoral condyle without concomitant MAT by a single surgeon were compared with a matched group of patients who underwent OCA with concomitant MAT (ipsilateral compartment). The patients were matched per age, sex, body mass index, and number of previous ipsilateral knee operations ±1. Patient-reported outcomes, complications, reoperations, and survival rates were compared between groups. One hundred patients undergoing OCA (50 isolated, 50 with MAT) with a mean ± SD follow-up of 4.9 ± 2.7 years (minimum, 2 years) were included (age, 31.7 ± 9.8 years; 52% male). Significantly more patients underwent OCA to the medial femoral condyle (n = 59) than the lateral femoral condyle (n = 41, P < .0001). Patients underwent 2.7 ± 1.7 operations on the ipsilateral knee before OCA. There were no significant differences between the groups regarding reoperation rate (n = 18 for OCA with MAT, n = 17 for OCA without MAT, P = .834), time to reoperation (2.2 ± 2.4 years for OCA with MAT, 3.4 ± 2.7 years for OCA without MAT, P = .149), or failure rates (n = 7 [14%] for OCA with MAT, n = 7 [14%] for OCA without MAT, P > .999). There were no significant differences in patient-reported clinical outcome scores between the groups at final follow-up. There was no significant difference in failure rates between patients undergoing medial femoral condyle OCA (n = 12, 15.3%) and lateral femoral condyle OCA (n = 5, 12.2%, P = .665). These results imply that with appropriate surgical indications to address meniscus deficiency in patients otherwise indicated for OCA and despite the added surgical time and complexity of concomitant MAT, outcomes are favorable, with an 86% OCA graft survivorship at 5 years. This information can be used to counsel patients undergoing OCA with concomitant MAT as part of a knee joint preservation strategy.

Surgical fixation of displaced midshaft clavicle fractures is predominantly achieved with intramedullary (IM) or plate fixation. Both techniques have potential pitfalls: plate fixation involves greater periosteal stripping and protuberance of the implant, whereas IM fixation may be associated with implant-related complications, such as migration or skin irritation, which may lead to further surgery for implant removal. The aim of this study was to compare these two methods in simple (Robinson 2b.1) and multifragmentary (Robinson 2b.2) displaced midshaft clavicle fractures. A total of 133 consecutive patients who underwent surgical fixation for a displaced midshaft clavicle fracture with either IM fixation using a 2.5-mm Kirschner wire or plate fixation using an 8-hole Dynamic Compression Plate (DCP) were retrospectively reviewed. Follow-up was a minimum of 1 year. The patients were allocated into two injury groups: displaced simple 2-part fractures (64 IM vs. 16 DCP) and displaced multifragmentary fractures (27 IM vs. 26 DCP). The major observed outcome measures were: infection rate, non-union rate, reoperation rate and postoperative range of motion (ROM). Rates of non-union for displaced 2-part fractures were 2/64 (3.13%) with IM fixation and 0/16 (0.00%) with plate fixation (p = 0.477). For displaced multifragmentary fractures, rates of non-union were 2/27 (7.41%) with IM fixation and 0/26 (0.00%) with plate fixation (p = 0.161). No significant difference was observed between the two fixation modalities in patient-reported time to regain ROM on the injured side for displaced 2-part fractures (p = 0.129) and displaced multifragmentary fractures (p = 0.070). Deep infection rate was zero (p = 1.000) overall in the study, and reoperation rate for IM and plate fixation, respectively, was 3.13% and 6.25% in the Robinson 2b.1 group (p = 0.559) and 7.41% and 7.69% in the Robinson 2b.2 group (p = 0.969). IM fixation of displaced midshaft clavicle fractures (Robinson 2b.1) has an equivalent non-union rate to plate fixation and similarly low complication and reoperation rates. For displaced midshaft multifragmentary clavicle fractures (Robinson 2b.2), the higher non-union rates observed with IM fixation leads us to recommend consideration of plate fixation for Robinson 2b.2 fractures. © 2017 Elsevier Ltd.

Surgical treatment of active infective endocarditis requires not only hemodynamic repair, but also special emphasis on the eradication of the infectious focus to prevent recurrence. This goal can be achieved by the combination of aggressive debridement of infective tissue and appropriate and adequate antibiotic treatment. We reviewed our experience with active endocarditis and identified factors determining early and late outcomes, particularly focusing on the factor of culture-negative endocarditis. Sixty seven patients with clinical evidence of active endocarditis who underwent operation between 1991 and 2001 were evaluated. The aortic valve was infected in 28 (42%), the mitral valve in 23 (34%), and multiple valves in 16 (24%). Native valve endocarditis was present in 58 (87%) and prosthetic valve endocarditis in 9 (13%). Mean follow-up was 5.7 years (range, 0.2-11.5 years). Microorganisms were detected in 46 (69%): Staphylococcus aureus in 9 (13%), other staphylococci in 9 (13%), streptococcus species in 19 (28%), and others in 9 (28%), whereas 21 (31%) patients had culture-negative endocarditis. Operative mortality was 17.8% (12 patients). Reoperation was required in 8 (12%), while 3 late deaths (5.5% of hospital survivors) occurred. All events, including death, reoperation, periprosthetic leak, and recurrence of infection, occurred within 2 years after operation. Actuarial freedom from reoperation, late survival, and events at 5 years were 81.6, 76.4, and 68.6%, respectively. On multivariate analysis, no independent adverse predictor was detected for hospital death, whereas the following independent adverse predictors were identified: preoperative heart failure (P=0.0375), prosthetic valve endocarditis (P=0.0391) and culture-negative endocarditis (P=0.0354) for poor late survival; culture-negative endocarditis (P=0.0354) and annular abscess (P=0066) for poor event-free survival. Freedom from events was similar between patients with Staphylococcus aureus infection (3-year freedom 55.6%) and culture-negative endocarditis (3-year freedom 47.6%), whereas events were significantly low in patients with streptococcus infection (3-year freedom 100%). In our analysis, no independent adverse predictor was detected for hospital death; however, culture-negative endocarditis was identified as an independent predictor for both late survival and events after surgery. Event-free survivals were similar between staphylococcus infection and culture-negative endocarditis, and all events occurred within 2 years after operation, suggesting the necessity of close follow-up during that period.

An ostomy seems a safe alternative in neonates with an acute abdomen when immediate restoration of bowel continuity is deemed undesirable. Faced with several complications in our center, and the feeling we are not the only center with these complications, we decided to assess the rate and type of complications after both ostomy creation and closure. All data regarding neonates (<30 days of age) who underwent a laparotomy for a suspected abdominal emergency in the period 2000 to 2010 were retrospectively analyzed. These data included demographics such as gender, gestational age, and birth weight. Disease etiology was defined and various features of the enterostomy were analyzed. These features included type, location, time to ostomy take down, and complications and mortality directly related to both creation and closure of the ostomy. A total of 155 patients who underwent a laparotomy for suspect acute abdomen were identified. Median gestational age was 33 weeks (range 25 to 40) and median birth weight was 1926 g (range 560 to 4380). Median age at laparotomy was 8 days (range 0 to 30). Indications for surgery were necrotizing enterocolitis (n = 38), spontaneous intestinal perforation (n = 11), intestinal atresia (n = 9) or obstruction (n = 5), and volvulus (n = 4). An ostomy was created in 67 patients (67/155: 43%): 38 boys and 29 girls. There were 8 jejuno-, 49 ileo-, and 10 colostomies created. In almost all cases (94%), a mucous fistula was also constructed.In 23 patients (23/67: 34%) ostomy-related complications occurred. Most frequent were high output ostomy (n = 10) and necrosis of the enterostomy (n = 7). Due to either one of the complications, nine patients (9/67: 13%) needed a reoperation.In this study, 11 patients died before ostomy closure could occur. In 53 patients, the ostomy was closed after a median of 107 days (range 4 to 299).After ostomy closure, complications occurred in 13 cases (13/53: 25%). Seven patients (7/53: 13%) needed another reoperation because of anastomotic leakage (n = 4), adhesions (n = 2), or incisional hernia (n = 1). There was no closure-related mortality. Although creating a temporary ostomy in newborns is preferable in certain situations, there is a considerable occurrence of complications and reoperations.

Fifty-two patients with rectal prolapse have been treated by the silicone rubber band perianal suture technique and satisfactory results have been obtained in 46 (89%). Eleven patients required reoperation to achieve this result. The procedure is a minor one, with little morbidity and no mortality. Provided that faecal impaction can be avoided in patients having this operation a successful outcome, can be expected. It is recommended especially for the frail and elderly with rectal prolapse.

1992-09-01

The operative management and clinical course of 17 patients treated for severe pancreatico-duodenal injuries from 1983 to 1990 was reviewed. The etiology of these injuries was gunshot wound in 15 patients; stab wound in 1 patient; and a motor vehicle accident in 1 patient. Seven patients presented in shock with a systolic blood pressure of less than 80. At exploration, 57 associated injuries were found in the 17 patients including 16 major vascular injuries. All patients were treated with pyloric exclusion and drainage. Vagotomy was performed in eight patients. None of these 17 patients were felt to have extensive enough damage to require pancreatico-duodenectomy. Two patients died in the immediate postoperative period of severe coagulopathy and two patients died of sepsis. Seven patients had complications related to the pancreatico-duodenal injury. All seven developed pancreatic fistulas; three also had pancreatitis and two developed multiple enterocutaneous fistulas. Systemic complications included pulmonary complications in eight patients and sepsis in five patients, including two patients with abdominal abscesses. Six patients bled in the immediate postoperative period secondary to coagulopathy. Three patients had complications related to pyloric exclusion. One developed afferent loop syndrome necessitating reoperation. The other two had marginal ulcers, which either perforated or bled and required reoperation. Of interest, neither of these two patients had vagotomy initially. The results of this series confirm the effectiveness of pyloric exclusion with vagotomy for severe pancreatico-duodenal injury.

Late Corrective Arthrodesis in Nonplantigrade Diabetic Charcot Midfoot Disease Is Associated with High Complication and Reoperation Rates

PubMed Central

Wussow, Annekatrin

2015-01-01

Introduction. Charcot arthropathy may lead to a loss of osteoligamentous foot architecture and consequently loss of the plantigrade alignment. In this series of patients a technique of internal corrective arthrodesis with maximum fixation strength was provided in order to lower complication rates. Materials/Methods. 21 feet with severe nonplantigrade diabetic Charcot deformity Eichenholtz stages II/III (Sanders/Frykberg II/III/IV) and reconstructive arthrodesis with medial and additional lateral column support were retrospectively enrolled. Follow-up averaged 4.0 years and included a clinical (AOFAS score/PSS), radiological, and complication analysis. Results. A mean of 2.4 complications/foot occurred, of which 1.5/foot had to be solved surgically. 76% of feet suffered from soft tissue complications; 43% suffered hardware-associated complications. Feet with only 2 out of 5 high risk criteria according to Pinzur showed significantly lower complication counts. Radiographs revealed a correct restoration of all foot axes postoperatively with superior fixation strength medially. Conclusion. Late corrective arthrodesis with medial and lateral column stabilization in the nonplantigrade stages of neuroosteoarthropathy can provide reasonable reconstruction of the foot alignment. Nonetheless, overall complication/reoperation rates were high. With separation into low/high risk criteria a helpful guide in treatment choice is provided. This trial is registered with German Clinical Trials Register (DRKS) under number DRKS00007537. PMID:26000309

Early anastomotic leakage (AL), usually defined as leakage within 30 post-operative days, represents a severe entity. However, mounting evidence has indicated that majorities of leakage occur within one week after surgery, making late AL rarity. Here we analyzed 101 consecutive colorectal AL, all of which occurred within 30 post-operative days, during Jan 2013 and Dec 2015 in cancer hospital of Fudan University. AL occurring within 5 post-operative days was defined as very early AL (vE-AL). We evaluated risk factors of vE-AL compared with non-vEAL and correlated with post-leakage peritonitis and need of relaparatomy. We found that AL occurred at median time of 7 days after surgery. 23 cases were vE-AL. Reconstruction of post-peritoneum for mid-low rectal carcinoma significantly reduced incidence of vE-AL compared with non-vE-AL (p = 0.042). Patients with vE-AL was associated with presence of peritonitis (p = 0.031), the latter significantly correlated with increased re-operation rate (p = 6.8E-13). Besides, patients with vE-AL trended to correlate with increased re-operation rate after leakage (p = 0.088). In concludsion, vE-AL occurring within 5 post-operative days represents a severe subtype associated with general peritonitis and need of relaparatomy. PMID:28084305

Background Total hip arthroplasty (THA) is very frequently performed. Despite low complication rates, revisions play an important clinical and economical role. The aim of this study was to identify comorbid diseases of patients undergoing primary THA and their potential influence on the survival of hip replacements. Patients/Material and Methods A total of 867 patients were included in this retrospective study. All revisions were reviewed that took place at our hospital within one year of primary implantation of THA. Comorbid diseases were detected by administrative data, using the Elixhauser definition, which includes thirty diseases. The Cox regression model and Fisher's exact test were used to examine correlations between comorbidities and risk of revision. Results 41 Patients required re-operation within the first year of surgery. The presence of one or more of the analysed comorbidities was associated with a greater risk of revision. Deficiency anemia, obesity, drug abuse, alcohol abuse, fluid and electrolyte disorders and peripheral vascular disorders were associated with increased risk of revision (p < 0.05 for all comparisons). The total number of comorbidities and specific comorbid diseases was independently associated with an increased risk of re-operation within the first year of total hip arthroplasty. This information could be helpful in pre- and post-operative risk adjustment and patient selection. Georg Thieme Verlag KG Stuttgart · New York.

[Tricuspid valve regurgitation : Indications and operative techniques].

PubMed

Lange, R; Piazza, N; Günther, T

2017-11-01

Functional tricuspid valve (TV) regurgitation secondary to left heart disease (e.g. mitral insufficiency and stenosis) is observed in 75% of the patients with TV regurgitation and is thus the most common etiology; therefore, the majority of patients who require TV surgery, undergo concomitant mitral and/or aortic valve surgery. Uncorrected moderate and severe TV regurgitation may persist or even worsen after mitral valve surgery, leading to progressive heart failure and death. Patients with moderate to severe TV regurgitation show a 3-year survival rate of 40%. Surgery is indicated in patients with severe TV regurgitation undergoing left-sided valve surgery and in patients with severe isolated primary regurgitation without severe right ventricular (RV) dysfunction. For patients requiring mitral valve surgery, tricuspid valve annuloplasty should be considered even in the absence of significant regurgitation, when severe annular dilatation (≥40 mm or >21 mm/m 2 ) is present. Functional TV regurgitation is primarily treated with valve reconstruction which carries a lower perioperative risk than valve replacement. Valve replacement is rarely required. Tricuspid valve repair with ring annuloplasty is associated with better survival and a lower reoperation rate than suture annuloplasty. Long-term results are not available. The severity of the heart insufficiency and comorbidities (e.g. renal failure and liver dysfunction) are the essential determinants of operative mortality and long-term survival. Tricuspid valve reoperations are rarely necessary and associated with a considerable mortality.

2007-02-01

Bicuspid anatomy of the aortic valve is a common reason for aortic regurgitation and is associated with aortic dilatation in more than 50% of patients. We have observed different patterns of aortic dilatation and used different approaches preserving the valve. Between October 1995 and February 2006, a regurgitant bicuspid valve was repaired in 173 patients. The aorta was normal in 57 patients who underwent isolated repair. Aortic dilatation mainly above commissural level (n = 38) was treated by separate valve repair plus supracommissural aortic replacement. In 78 patients, aortic dilatation involved the root and was treated by root remodeling. Hospital mortality and perioperative morbidity were low in all three groups. Myocardial ischemia was significantly shorter in repair plus aortic replacement than remodeling (p < 0.001). Freedom from aortic regurgitation II or greater at 5 years varied between 91% and 96%. Freedom from reoperation at 5 years was 97% after remodeling, but only 53% after repair plus aortic replacement (p = 0.33). Symmetric prolapse was the most frequent cause for reoperation. The long-term stability of bicuspid aortic valve repair is excellent in the absence of aortic pathology. In the presence of aortic dilatation, root remodeling leads to equally stable valve durability. In patients with less pronounced root dilatation, separate valve repair plus aortic replacement may be a less complex alternative. Symmetric prolapse should be avoided if the ascending aorta is replaced.

Objectives Robotic sacrocolpopexy has been rapidly incorporated into surgical practice without comprehensive and systematically published outcome data. The aim of this study was to systematically review the current published peer-reviewed literature on robotic-assisted laparoscopic sacrocolpopexy with greater than six-month anatomic outcome data. Methods Studies were selected after applying predetermined inclusion and exclusion criteria to a MEDLINE search. Two independent reviewers blinded to each other’s results abstracted demographic data, perioperative information and postoperative outcomes. The primary outcome assessed was anatomic success rate defined as ≤POP-Q Stage 1. A random effects model was performed for meta-analysis of selected outcomes. Results 13 studies were selected for the systematic review. Meta-analysis yielded a combined estimated success rate of 98.6% (95%CI 97.0–100%). The combined estimated rate of mesh exposure/erosion was 4.1% (95%CI 1.4–6.9%), and the rate of reoperation for mesh revision was 1.7%. The rates of reoperation for recurrent apical and non-apical prolapse were 0.8% and 2.5% respectively. The most common surgical complication (excluding mesh erosion) was cystotomy (2.8%), followed by wound infection (2.4%). Conclusions The outcomes of this analysis indicate that robotic sacrocolpopexy is an effective surgical treatment for apical prolapse with high anatomic cure rate and low rate of complications.

This study compared the outcomes of infants who underwent surgery in neonatal intensive care units by pediatric surgeons and by general surgeons. This was a retrospective study of infants who underwent surgery in neonatal intensive care units between 2010 and 2014. A total of 227 patients were included. Of these patients, 116 were operated on by pediatric surgeons (PS) and 111 were operated on by general surgeons (GS). The outcome measures were the overall rate of operative complications, unplanned reoperation, mortality rate, length of stay, operative time, and number of total number of operative procedures. The overall operative complication rate was higher in the GS group compared with the PS group (18.7% vs. 7.0%, p=0.0091). The rate of unplanned reoperations was also higher in the GS group (10.8% vs. 3.5%, p=0.0331). The median operation time (90min vs. 75min, p=0.0474) and median length of stay (24days vs. 18days, p=0.0075) were significantly longer in the GS group. The adjusted odd ratios of postoperative complications for GS were 2.9 times higher than that of PS (OR 2.90, p=0.0352). The operative quality and patient outcomes of the PS group were superior to those of the GS group. III. Copyright © 2017 Elsevier Inc. All rights reserved.

To evaluate the preoperative features, intraoperative management, and postoperative outcomes of recurrent macular holes that developed after initial successful repair with small-gauge vitrectomy techniques. We retrospectively reviewed 392 eyes with idiopathic macular holes successfully treated with small-gauge vitrectomy. Thirteen of these eyes underwent reoperation after macular hole reopening. We assessed patient demographics, visual acuity, postoperative anatomical success, potential precipitating clinical factors of hole reopening, and details of the surgical repairs of these eyes. Macular hole reopening occurred in 13 (3.3%) of 392 eyes in a mean of 28 months (range, 1-120 months) after initial repair. All 13 recurrent holes closed after a second vitrectomy, but 4 (31%) holes reopened again and had vitrectomy. Of these, 2 reopened a third time. Ultimately, 11 (85%) holes were closed at the most recent follow-up. The mean best-corrected visual acuity was 20/81 before initial repair, 20/148 after the first reopening, 20/115 after repair of the first reopening, and 20/55 after repair of >1 reopening. Ten of 13 (77%) patients had, or later developed, macular holes in the other eye during follow-up. Reoperation successfully achieved hole closure and ultimate visual improvement in most eyes with recurrent macular holes. Most patients with recurrent holes previously had, or later developed, full-thickness macular holes in the other eye.

A retrospective study for a period of 5 years in general surgery department, Habib Bourguiba hospital, Sfax, including all patients operated with confection of a colostomy. Were then studied patients reoperated for stoma complication. Among the 268 patients who have had a colostomy, 19 patients (7%) developed surgical stoma complications. They had a mean age of 59 years, a sex ratio of 5.3 and a 1-ASA score in 42% of cases. It was a prolapse in 9 cases (reconfection of the colostomy: 6 cases, restoration of digestive continuity: 3 cases), a necrosis in 5 cases (reconfection of the colostomy), a plicature in 2 cases (reconfection of the colostomy) a peristomal abscess in 2 cases (reconfection of the colostomy: 1 case, restoration of digestive continuity: 1 case) and a strangulated parastomal hernia in 1 case (herniorrhaphy). The elective incision and the perineal disease were risk factors for the occurrence of prolapse stomial. Surgical complications of colostomies remain a rare event. Prolapse is the most common complication, and it is mainly related to elective approach. Reoperation is often required especially in cases of early complications, with usually uneventful postoperative course.

Postoperative peritonitis is a pathologic condition with a sometime nuclear clinical occurrence and therefore with an uncertain timing for reoperation. Aim of this paper is to identify the type and frequency of the digestive and systemic symptoms in relation to the anatomo-pathologic peroperative picture. Between 1980 and 1996, 119 patients were reoperated for a postoperative peritonitis (PPO) in the Surgical Department of Modena University. PPO was due to a lesion situated above the mesocolon in 33 patients, from the small bowel in 18, postappendicectomy in 25 and from the colon in 40. The first operation (for benign disease in 66.4%, for malignancy in 33.6%) was performed in emergency in 47 cases (39.5%) and as elective surgery in 72 (60.5%). The global mortality was of 33.6% (40 patients). An attempt is made to identify, the earlier and the most important bioclinical parameters for a correct indication to surgery. Twenty symptoms have been identified that, with different frequency, are strictly related with the onset of a PPO (in average 5 symptoms were positive). A research of these parameters, each 4-6 hours, allow to identify a subclinical PPO. During the decisional timing, it is important to check these general and digestive symptoms, apparently not serious, in order to avoid the onset appearance of an abdominal tenderness or a multiorgan failure that make the prognosis more severe.

Complimentary use of epicardial echo imaging and Doppler in quantification of coronary artery stenoses

As more advanced therapeutic procedures are performed on coronary arteries during open chest surgery more advanced diagnostic procedures will be required to define the location and severity of coronary artery disease. This manuscript describes our preliminary experiences in identifying human coronary artery stenoses using epicardial two-dimensional color flow Doppler. Once the lesions were identified we used standard echo Doppler and imaging techniques to define their severity. The accuracy of stenotic cross sectional area calculated using the continuity equation and pressure gradient calculated using the Bernoulli equation were defined using a pulsatile flow model of the coronary circulation. Suggestions about further hardware development required to allow easy clinical application of this technique are described. 1 - CLINICAL NEED FOR INTRA-OPERATIVE EVAUJATION OFCORONARY ARTERIES The severity of coronary artery disease in adults who require coronary bypass surgery has changed significantly in the last ten years. More effective medications used to control angina pectoris and the wide use of percutaneous y artery angioplasty have delayed the timing of surgery until atherosclerotic involvement is more extensive. In addition patients who have had initial coronary bypass operations are now reaching ages at which atherosclerotic involvement of their bypass grafts and native vessels has progressed and reoperation is required. To meet the challenge of coronary arteries with multiple lesions or diffuse disease intraoperative angioplasty devices are being developed.

We have performed a retrospective comparative study between the trochanteric gamma nail (TGN) and the proximal femoral nail (PFN). During the period 1998-2003, 97 TGN and 83 PFN were used for the treatment of pertrochanteric fractures. Most of the fractures were of the A3 type according to the AO/ASIF classification. Clinical and radiological follow-ups were available for 87 TGN and 65 PFN. The mean operative time for the TGN was shorter than that for the PFN. Intraoperative complications were noted in 17.5 % and 28.8 % for the TGN and PFN groups, respectively. Late complications occurred in 18.4 % for TGN compared to 27.6 % of the PFN. Union was achieved in 94.2 % and 89.3 % of the patients treated with the TGN and PFN, respectively. The reoperation rates were 10.3 % and 24.6 % for the TGN and the PFN, respectively. Clinical outcomes were good for both groups (65 % in the TGN, 62 % in the PFN group). Treatment of pertrochanteric fractures using the TGN and PFN implants is quite reliable. The major complication was cut-out and occurred mostly in the PFN group, while varus deformity was more frequent in the TGN group. The PFN was associated with a higher rate of reoperation and longer operative time, probably due to a more demanding technique.

Data was collected from a prospective database of GI and hepato-pancreato-biliary service, TMC, Mumbai from January 2008 to December 2016. Forty patients with periampullary/pancreatic head tumours were referred to us after exploration. Thirty were planned for re-exploration, of whom 25 patients underwent successful R-PD, either upfront (n = 12) or after neo-adjuvant therapy (n = 13). Twenty were adenocarcinomas, 5 had other histologies. Majority of the patients were deemed inoperable in view of suspected vascular involvement at the time of initial surgery (68%). R0 resection was achieved in 90% of adenocarcinoma cases (n = 18). Postoperative major morbidity was 20% and mortality was 4% (n = 1). The estimated 1-, 2- and 5-year survival for those with adenocarcinoma was 83, 71.2, and 29.9% respectively. R-PD is safe and should be performed in experienced centres and can achieve long-term outcomes, comparable to conventional PD. The most common reason for denying resection at initial surgery was suspected or perceived vascular involvement. © 2018 S. Karger AG, Basel.

Symptomatic hypermobile kidney is treated with nephropexy, a surgical procedure through which the floating kidney is fixed to the retroperitoneum. Although both open and endoscopic procedures have a high success rate, they can be associated with risk of complications, relatively long hospital stay and high cost. We describe our percutaneous technique for fixing a hypermobile kidney and evaluate the efficacy of the percutaneous nephrostomy insertion in management of symptomatic nephroptosis. Between January 2005 and December 2011, 11 patients diagnosed with a symptomatic right nephroptosis of at least 1 year duration were treated with a single point percutaneous nephrostomy technique. All data were retrieved from patients' medical records and then retrospectively analysed. Nephropexy through a single point percutaneous nephrostomy technique was successfully accomplished in 11 women. The mean operative time was 20 min. The intraoperative estimated blood loss was minimal in all cases. No major or minor intraoperative complications were noted. The average postoperative hospital stay was 2 days. Women returned to their usual activities 14 days following the surgery. Nine women had complete resolution of their pain, and 2 patients continued to complain of discomfort in their lumbar area. One patient was re-operated upon with satisfactory subjective and objective outcomes achieved. One patient refused re-operation. Percutaneous nephropexy is simple, inexpensive and effective for treatment of symptomatic hypermobile kidney. It remains a valuable alternative to open, laparoscopic, and robotic methods for fixing a floating kidney.

Background: Peripheral arterial disease (PAD) affects 3%–10% of the population before the age of 70 years and 15%–20% after that age. The aim of the study was to compare the incidence of complications and secondary interventions in patients who underwent each type of treatment. Methods: We analyzed 734 medical records of the Department of Surgery at the 4th Military Teaching Hospital in Wroclaw, In total, 394 were operated on with open surgery; an endarterectomy (59.39%), a vascular prosthesis implantation (31.01%), or both of these techniques (6.6%), and 340 patients had angioplasty with (50.59%) or without stenting (49.41%). Results: There were no statistically significant differences in the incidence of corresponding complications. The exception was the infection of the wound; significantly fewer were reported in the case of endovascular procedures (p = 0.0087). There were 12 occasions (3.53%) during endovascular surgeries when intraoperative conversion or re-operation using the open method occurred. In the case of open surgery, the mean hospital stay was 7.77 days (median: 8, mode: 8), while for endovascular management it was equal to 4.68 days (median: 4, mode: 3), p <0.0001. Conclusion: The endovascular method results in a similar re-operation rate and number of complications as open surgery. PMID:28496017

In patients with previous heart surgery, the operative risk is elevated during conventional aortic valve re-operations. Trans-catheter aortic valve implantation is a new method for the treatment of high-risk patients. Nevertheless, this new procedure carries potential risks in patients with previous homograft implantation in aortic position. Between April 2008 and February 2011, 345 consecutive patients (mean EuroSCORE (European System for Cardiac Operative Risk Evaluation): 38 ± 20%; mean Society of Thoracic Surgeons (STS) Mortality Score: 19 ± 16%; mean age: 80 ± 8 years; 111 men and 234 women) underwent trans-apical aortic valve implantation. In three patients, previous aortic homograft implantation had been performed. Homograft degeneration causing combined valve stenosis and incompetence made re-operation necessary. In all three patients, the aortic valve could be implanted using the trans-apical approach, and the procedure was successful. In two patients, there was slight paravalvular leakage of the aortic prosthesis and the other patient had slight central leakage. Neither ostium obstruction nor mitral valve damage was observed. Trans-catheter valve implantation can be performed successfully after previous homograft implantation. Particular care should be taken to achieve optimal valve positioning, not to obstruct the ostium of the coronary vessels due to the changed anatomic situation and not to cause annulus rupture.

Image-guidance and navigation in spinal surgery is becoming more widely utilized. Several studies have shown the use of this technology to increase accuracy of pedicle screw placement, decrease the rates of revision surgery, and minimize radiation exposure. In this paper, the authors analyze the economics of image-guided surgery (IGS) and navigation in spine surgery. A literature review was performed using PubMed, the CEA Registry, and the National Health Service Economic Evaluation Database. Each article was screened for inclusion and exclusion criteria, including costs, reoperation, readmission rates, operating room time, and length of stay. Thirteen studies were included in the analysis. Six studies were identified to meet the inclusion criteria for reporting costs and seven met the criteria for analysis of efficacy. Average costs ranged from $17,650 to $39,643. Pedicle screw misplacement rates using IGS ranged from 1.20% to 15.07% while reoperation rates ranged from 0% to 7.42%. There is currently an insufficient amount of studies reporting on the economics of spinal navigation to accurately conclude on its cost-effectiveness in clinical practice. Although a few of these studies showed less costs associated with intraoperative imaging, none were able to establish a statistically significant difference. Preliminary findings drawn from this study indicate a possible cost-effectiveness advantage with IGS, but more comprehensive data on costs need to be reported in order to validate its utilization.

Gastrectomy remains the primary therapeutic method for resectable gastric cancer. Thought of as an important measure to reduce post-operative complications and mortality, abdominal drainage was used widely after gastrectomy for gastric cancer in previous decades. The benefits of abdominal drainage have been questioned by researchers in recent years. The objectives of this review were to access the benefits and harms of routine abdominal drainage post gastrectomy for gastric cancer. We searched the Cochrane Controlled Trials Register (Central/CCTR) in The Cochrane Library (2010, Issue 10), including the Specialised Registers of the Cochrane Upper Gastrointestinal and Pancreatic Diseases (UGPD) Group; MEDLINE (via Pubmed, 1950 to October, 2010); EMBASE (1980 to October, 2010); and the Chinese National Knowledge Infrastructure (CNKI) Database (1979 to October, 2010). We included randomised controlled trials (RCTs) comparing abdominal drain versus no drain in patients who had undergone gastrectomy (not considering the scale of gastrectomy and the extent of lymphadenectomy; irrespective of language, publication status, and the type of drain). We excluded RCTs comparing one drain with another. From each trial, we extracted the data on the methodological quality and characteristics of the included studies, mortality (30-day mortality), re-operations, post-operative complications (pneumonia, wound infection, intra-abdominal abscess, anastomotic leak, drain-related complications), operation time, length of post-operative hospital stay and initiation of soft diet. For dichotomous data, we calculated the risk ratio (RR) and 95% confidence intervals (CI). For continuous data, we calculated mean differences (MD) and 95% CI. We tested heterogeneity using the Chi(2) test. We used a fixed-effect model for data analysis with RevMan software but we used a random-effects model if the P value of the Chi(2) test was less than 0.1. We included four RCTs involving 438 patients (220 patients in the drain group and 218 in the no-drain group).There was no evidence of a difference between the two groups in mortality (RR 1.73, 95% CI 0.38 to 7.84); re-operations (RR 2.49, 95% CI 0.71 to 8.74); post-operative complications (pneumonia: RR 1.18, 95% CI 0.55 to 2.54; wound infection: RR 1.23, 95% CI 0.47 to 3.23; intra-abdominal abscess: RR 1.27, 95% CI 0.29 to 5.51; anastomotic leak: RR 0.93, 95% CI 0.06 to 14.47); and initiation of soft diet (MD 0.15 day, 95% CI -0.07 to 0.37). However, the addition of a drain prolonged the operation time (MD 9.07 min, 95% CI 2.56 to 15.57) and post-operative hospital stay (MD 0.69 day, 95% CI 0.18 to 1.21) and lead to drain-related complications. Additionally, we should note that 30-day mortality and re-operations are very rare events and, as a result, very large numbers of patients would be required to make any sensible conclusions about whether the two groups were similar. The overall quality of the evidence according to the GRADE approach was "Very Low" for mortality and re-operations, and "Low" for post-operative complications, operation time, and post-operative length of stay. We found no convincing evidence to support routine drain use after gastrectomy for gastric cancer.

OBJECTIVE Successful transsphenoidal surgery for adrenocorticotropin hormone (ACTH)-producing pituitary tumors is associated with subnormal postoperative serum cortisol levels, which may guide decisions regarding immediate reoperation. However, little is known about the detailed temporal course of changes in serum cortisol in the immediate postoperative period, and the relationship of postoperative cortisol dynamics to remission and late recurrence. METHODS A single-center retrospective cohort analysis was performed for all patients undergoing pituitary surgery from 2007 through 2015. Standardized diagnostic and treatment algorithms were applied to all patients with potential Cushing's disease (CD), including microsurgical transsphenoidal adenomectomy (TSA) by a single surgeon. All patients had serum cortisol levels drawn at 6-hour intervals for 72 hours after surgery, and were offered reoperation within 3 days for normal or supranormal postoperative cortisol levels. Primary outcomes were 6-month remission and late recurrence; secondary outcomes were persistent postoperative hypocortisolism and surgical morbidity. Discriminatory levels of postoperative serum cortisol for predicting remission were calculated at various intervals after surgery using receiver operating characteristic (ROC) curves. RESULTS Among 89 patients diagnosed with CD, 81 underwent initial TSA for a potentially curable lesion; 23 patients (25.8%) underwent an immediate second TSA. For the entire cohort, 6-month remission was achieved in 77.8% and late recurrences occurred in 9.5%, at a mean of 43.5 months. Compared with patients with a single surgery, those with an immediate second TSA had similar rates of remission (78.3% vs 77.6%) and late recurrence (5.6% vs 11.1%). The rate of hypocortisolism for patients with 2 surgeries (12/23, 52.2%) was significantly greater than that for patients with single surgeries (13/58, 22.4%; p < 0.001). There was no difference in the incidence of CSF leaks between the first and second operations. Remission was achieved in 58 (92.1%) of 64 patients who completed the 2-surgery protocol. The temporal course of postoperative serum cortisol levels among patients varied considerably, with subnormal nadir levels < 2 μg/dl occurring between 12 hours and 66 hours. Patients achieving remission had significantly lower mean serum cortisol levels at every time point after surgery (p < 0.01). By ROC curve analysis, nadir cortisol levels < 2.1 μg/dl were predictive of 6-month remission for the entire cohort over 3 days (positive predictive value [PPV] = 94%); discriminating cortisol levels for predicting remission on postoperative day (POD) 2 were < 5.4 μg/dl (PPV = 97%), although patients with remission after postoperative cortisol levels of 2-5 μg/dl had a significantly higher rate of late recurrence. CONCLUSIONS There is substantial variation in the temporal course of serum cortisol levels over the first 72 hours after TSA for CD, with nadir levels predictive for remission occurring as late as POD 3. Although a cortisol level of 2.1 μg/dl at any point was an accurate predictor of 6-month remission, levels less than 5.4 μg/dl on POD 2 were reasonably accurate. These data may enable decisions regarding the efficacy of an immediate second surgical procedure performed during the same hospitalization; immediate reoperation is associated with excellent remission rates and low recurrence rates in patients otherwise unlikely to achieve remission, but carries a higher risk of permanent hypocortisolism.

Hypersensitivity to stainless steel sternal sutures are an uncommon occurrence. We present a case of such a patient who developed chronic tissue overgranulation over a sternotomy wound eight weeks post-operatively. Primary suspicion was infection, a more common complication however radiological and laboratory investigation showed otherwise. Conservative management provided limited ephemeral success. After ensuring adequate sternal bone healing, the sutures and granulation tissue were eventually surgically removed without complication and the reoperated wound healed well.

The paper describes the method used to create a preternatural anus in terminal stomas using a mechanical circular stapler (Model EEA-31). Two methods are put forward: Chung's and Burke's methods (the latter of which was used by our department). A mechanical circular stapler has been used several times (13) to perform this type of stoma, with excellent esthetic and functional results, both immediate and long-term. It was only necessary to reoperate in one case in order to suspend the affected colic loop.

Iatrogenic aortic valve (AV) perforation during non-aortic cardiac operations is a rare complication. The suture-related inadvertent injury to an AV leaflet can produce leaflet perforation with aortic regurgitation after ventricular septal defect repair (VSDR). We report three consecutive patients who had iatrogenic aortic leaflet perforation during VSDR in other hospitals and referred to our hospital for reoperation. In all three cases, the perforated AV leaflets were preserved and repaired by autologous pericardial patch or direct local closure. PMID:29057770

Background Silicone breast implants have long been used for breast augmentation and reconstruction. During this time, these medical devices have gone through a number of modifications to improve their safety, quality, and clinical outcome performance. Objectives The authors conducted a 10-year study to determine the safety and effectiveness of Natrelle 410 silicone breast implants. Methods This prospective, multicenter study enrolled 941 subjects who were undergoing either augmentation, augmentation revision, reconstruction, or reconstruction revision. Data on complications, reoperations, explantations, and subject satisfaction were collected at annual clinic visits, and one-third of subjects underwent biennial magnetic resonance imaging (MRI) to screen for implant rupture. The authors used the Kaplan-Meier estimator to calculate risk rates for local complications, reoperations, and explantations. Results Capsular contracture rates increased approximately 1% per year from the previously reported 6-year rates. The rates were significantly lower than those from the Natrelle round gel core study. The overall rate of confirmed ruptured implants in subjects who underwent MRI was 5.7%. Eleven late seromas were reported. The most common reason for explantation was a subject requesting a size or style change. Satisfaction rates remained high through 10 years, with most subjects saying they were somewhat or definitely satisfied with their implants. Conclusions This 10-year prospective trial demonstrated the long-term safety and effectiveness of Natrelle 410 anatomical form-stable implants. The complication rates were low and the satisfaction rates were high. Level of Evidence: 1 Therapeutic PMID:25717116

Benign multinodular goiter (BMNG) is the most common endocrine disease requiring surgery. During the last few years a more aggressive approach has become the trend for bilateral BMNG treatment. Randomized clinical trials of any size that compared bilateral subtotal resection, Dunhill procedure and total thyroidectomy for benign multinodular goiter, published between January 2000 and the end of March 2015, were reviewed. Total thyroidectomy can be considered the most reliable approach in preventing recurrence. The Dunhill procedure is related to a higher rate of recurrence, but rarely recurrences after Dunhill procedure lead to reoperation. Total thyroidectomy avoid completion thyroidectomy for incidental carcinoma and its related risks. Recurrent laryngeal nerve (RLN) palsy becomes less common as surgical experience increases. Transient and permanent hypoparathyroidism is strictly related to the extent of neck dissection. In the risk-cost analysis we must consider the type of patient candidated to surgery and the impact of the surgical protocol we apply. When thyroid surgery is taken in consideration, specific complication rates of different procedures in each hospital must be analyzed accordingly to patient-specific risk factors and local expertise. The Dunhill procedure seems to be a good compromise between radicality and prevention of complications, avoiding reoperation for recurrence or completion thyroidectomy for incidental thyroid carcinoma. More follow-up studies and prospective studies are necessary to better evaluate, definitively, whether to prefer total thyroidectomy or Dunhill procedure in case of benign goiter surgery.

Bar flipping displacement is one of the most common complications after the Nuss procedure for pectus excavatum. We evaluated the results of a modified Nuss procedure with needlescope-assisted bar fixation. The records of 41 patients with pectus excavatum who underwent single pectus bar insertion with the Nuss procedure between July 2011 and August 2014 were retrospectively reviewed. The patients were divided into two groups: those who did not undergo 3-point fixation (group A) and those who did undergo 3-point fixation (group B). There were 36 male patients and 5 female patients with a mean age of 10.7 ± 8.3 years (range: 3-36 years). The postoperative Haller index (HI) (2.61 ± 0.42) was significantly lower than the preoperative HI (3.91 ± 1.07; p < 0.01). The angle of the initial bar position was 5.59 ± 7.37 degrees in group A and 8.52 ± 9.61 degrees in group B, with no significant difference between the groups (p > 0.05). The rate of reoperation to correct bar displacement was lower in group B (3.3%) than in group A (9.1%). Needlescope-assisted 3-point fixation of the bar was performed without an additional skin incision and showed a low rate of reoperation to correct displacement of the pectus bar.

While arthrodesis is the standard treatment of a severely arthritic ankle joint, total ankle arthroplasty has become a popular alternative. This review provides clinical outcomes and complications of both interventions in patients with rheumatoid arthritis. Studies were obtained from Pubmed, Embase and Web of Science (January 1980-June 2011) and additional manual search. original clinical study, > 5 rheumatoid arthritis (population), internal fixation arthrodesis or three-component mobile bearing prosthesis (intervention), ankle scoring system (outcome). The clinical outcome score, complication- and failure rates were extracted and the methodological quality of the studies was analysed. 17 observational studies of 868 citations were included. The effect size concerning total ankle arthroplasty ranged between 1.9 and 6.0, for arthrodesis the effect sizes were 4.0 and 4.7. Reoperation due to implant failure or reoperation due to non-union, was 11% and 12% for respectively total ankle arthroplasty and arthrodesis. The methodological quality of the studies was low (mean 6.4 out of a maximum of 14 points) and was lower for arthrodesis (mean 4.8) as compared to arthroplasty (mean 7.8) (p = 0.04). 17 observational and no (randomized) controlled clinical trials are published on the effectiveness of arthroplasty or arthrodesis of the ankle in rheumatoid arthritis. Regardless of the methodological limitations it can be concluded that both interventions show clinical improvement and in line with current literature neither procedure is superior to the other.

Laparoscopic anti-reflux surgery has become the standard treatment for symptomatic gastro-oesophageal reflux disease refractory to medical therapy. Successful anti-reflux surgery involves safe, minimally invasive surgery, resulting in symptom resolution with minimal side effects. This study aims to assess the feasibility and safety of day case anti-reflux surgery focussing on peri- and post-operative outcomes as a measure of success. Data was collected from the hospital database from 2003 to 2012. Data collection included demographics, surgeon, mode of admission, length of stay and complications. Electronic records were independently scrutinised for all patients with a length of stay of more than two nights. 723 patients underwent laparoscopic fundoplication ± small hiatus hernia repair (<5 cm) with a day case rate of 67.1%. The 30 day readmission rate in these patients was 2.9% (21/723 patients). Nine patients had a failure of their initial laparoscopic fundoplication (defined as recurrence of symptoms). Three patients required a re-operation within 12 months of their initial procedure (re-operation rate = 0.41% (3/723 patients)). Laparoscopic hiatal surgery can be performed safely as a day case in high volume specialist centres with good outcomes. Raising the national standard for day case fundoplication promotes good practice and should be the model for future commissioning. Crown Copyright © 2018. Published by Elsevier Ltd.

The Demons-Meigs syndrome should usually be evoked in case of presence of a typical triad: abdominopelvic mass, ascites and hydrothorax. Its diagnosis appears crucial to prevent the realization of unnecessary surgical procedures. A 32-year-old woman presented in April 2012 to the emergency department of our maternity unit (General Hospital, Thiers, France) with an abdominal distension mimicking the symptoms of a pregnancy at term. Physical examination revealed a voluminous painful abdominopelvic mass, extended from the pelvis to the upper abdomen with a large right pleural effusion. Ultrasound and computed tomography showed it was a tumor measuring more than 300 mm in diameter with a right hydrothorax. Serum CA-125 level was 289 U/ml. Cytologic analysis of the pleural effusion didn't show any malignant cells. In this study, Demons-Meigs syndrome was recognized. A laparoscopico-laparotomic management permitted an aspiration of 23 liters of a brownish liquid and an unilateral adnexectomy after pleural paracentesis was performed. Frozen section demonstrated benign mucinous cystadenoma. The final histologic findings objectified intracystic intestinal type ovarian mucinous borderline tumor. After multidisciplinary consultation, the patient was re-operated one month later. The exploration didn't reveal any suspected lesions and appendectomy and omentectomy were performed. The postoperative course was uneventful. Serum CA-125 level was normal at the time of the reoperation and 24 months after the initial surgery. The preoperative recognition of a Demons-Meigs syndrome or a Demons' pseudosyndrome is essential to avoid useless surgical procedures.

Since the advent of computed tomography, numbers and expertise in Lymphangiography (LAG) have markedly dropped. The intention of our study was to demonstrate the persisting diagnostic and therapeutic impact of LAG on the postoperative patient with known or suspected lymphatic vessel leakage. Between May 1, 1999, and April 30, 2006, we investigated pedal lipiodol-LAGs (18 monopedal, 2 bipedal) on 22 patients (16 male, 6 female) with known or suspected postoperative chylothorax, chylaskos, lymphocele, or lymphatic fistula. Ages varied from 26 to 81 years. The spectrum of operative procedures was broad: 6 thoracic, 5 abdominal, and 11 peripheral operations were performed. In 20 patients who underwent mono- or bipedal LAG for lymphatic vessel injury, we were able to demonstrate the specific site of leakage in 15 cases (75%) and found signs of extravasation in 5 patients (25%). Furthermore, in 11 patients (55%) we were able to avoid surgery because of closure of the leak after LAG. As the conservative therapeutic approach usually takes 2-3 weeks to reveal its therapeutic effects, 73.3% (11/15) of the patients who were not reoperated before this hallmark was passed did not need any further operation. Our study clearly demonstrates that even in the decades of modern cross-sectional imaging, classic LAG is a powerful and highly reliable tool to visualize and even assist occlusion of the postoperatively damaged lymphatic vessel and may thereby avoid the need for reoperation.

Recurrent chronic subdural hematoma (CSDH) is not rare. Some studies have demonstrated the role of dexamethasone in the medical management of chronic subdural hematoma. However, no systematic study in the treatment of recurrent CSDH has been published. The aim of our study is to evaluate the efficacy and safety of dexamethasone in patients with recurrent CSDH. We retrospectively reviewed medical records of consecutive patients from July 2010 to September 2014. A total of 27 patients with symptomatic recurrent CSDH were included in the analysis. Follow-up for each patient consisted of computed tomography or magnetic resonance imaging every 28 days from admission to the resolution of hematoma. Data were collected on hematoma volume, complications, and outcome. Among the 27 patients, 3 patients with recurrent CSDH were only treated by burr hole surgery. Of the other 24 patients who primarily underwent dexamethasone treatment, 17 (70.8%) patients were treated successfully with medical treatment, whereas 7 patients required reoperation. Complications were noted in 3 (12.5%) patients (1 hyperglycemia, 1 urinary tract infection, and 1 pneumonia). There was 1 mortality (4.2%) for massive brain infarction. Twenty-one of the 24 patients (87.5%) recovered to their previous functional levels. There was no statistical significance in Fisher text between surgery and dexamethasone regarding success, complication, and functional recovery rate. Patients with recurrent CSDH can be treated successfully and safely with the nonsurgical medical treatment of dexamethasone. By use of this method, reoperation may be avoided.

Since the advent of computed tomography, numbers and expertise in Lymphangiography (LAG) have markedly dropped. The intention of our study was to demonstrate the persisting diagnostic and therapeutic impact of LAG on the postoperative patient with known or suspected lymphatic vessel leakage. Between May 1, 1999, and April 30, 2006, we investigated pedal lipiodol-LAGs (18 monopedal, 2 bipedal) on 22 patients (16 male, 6 female) with known or suspected postoperative chylothorax, chylaskos, lymphocele, or lymphatic fistula. Ages varied from 26 to 81 years. The spectrum of operative procedures was broad: 6 thoracic, 5 abdominal, and 11 peripheral operations were performed.more » In 20 patients who underwent mono- or bipedal LAG for lymphatic vessel injury, we were able to demonstrate the specific site of leakage in 15 cases (75%) and found signs of extravasation in 5 patients (25%).

A new approach to the treatment of nasal bone fracture: radiologic classification of nasal bone fractures and its clinical application.

PubMed

Han, Daniel Seung Youl; Han, Yea Sik; Park, Jin Hyung

2011-11-01

A radiologic examination is required in the treatment of nasal bone fracture to determine the fracture condition. Thus, there is an increasing need for radiologic classification of nasal bone fractures that can be applied to clinical practice. Computed tomography was performed in 125 patients with nasal bone fractures to determine which axial view best showed the entire nasal view. The obtained axial view was then used as a reference for classification. The length from the top to the base of the nasal bone was divided into upper, middle, and lower levels, after which the fracture location was determined. If the fracture spanned the boundaries of these levels, it was classified as the total level. Subsequently, the fracture was subclassified based on the fracture direction and pattern and the concurrent fracture. Radiologic examination of patients with nasal bone fracture showed that nasal bone fracture was frequently found at the total, middle, upper, and lower levels, in that order. Nasal bone fractures at the upper level showed lower frequencies of complication and reoperation than the fractures at the other levels, whereas nasal bone fractures at the total level showed the highest frequencies of complication and reoperation. Radiologic classification can be useful for preoperative and postoperative evaluations of nasal bone fractures and can be helpful in understanding such fractures because it can efficiently predict the prognosis of a fracture.

To assess the feasibility of post-mortem surveillance for subclinical variant Creutzfeldt-Jakob disease (vCJD) at least 5 years after neurosurgical procedures. Using Scottish record linkage, we estimated 5-year survival and re-operation rates after 4 neurosurgical procedures performed during 1993-2001 and identified as high or medium risk for transmitting vCJD: [B] drainage of extra- or subdural haematoma, [E] primary or revisional decompression operations and [H] creation of other ventricular shunts were classified as high risk; [C] operations on cerebral aneurysm (clipping) were classified as medium risk. Fatality rate at 1 year depended strongly on procedure, weakly or not at all on sex and era, and increased with age. Procedure rates differed by sex. The rate of subsequent neurosurgical operations was highest for procedure [H] (sole: 21%; multiple: 28%). Each year, the UK has a new cohort of some 5,000 5-year survivors after a high- or medium-risk neurosurgical procedure, whose subsequent annual mortality is at least 3%. Even if half the surviving 5-year survivors of neurosurgery since 1996 gave consent-in-life for vCJD-informative testing at post-mortem, there would be too few relevant post-mortems in 2008-2010 (around 1,600) for 'nil detections' to exclude a 1 in 1,000 subclinical vCJD rate. Autopsy surveillance beyond 2010, or among 5-year survivors of non-neurosurgical at-risk operations, would be needed. (c) 2009 S. Karger AG, Basel.

Lung volume reduction surgery (LVRS) can benefit patients with severe emphysema. The aim of this study was to evaluate the outcome of LVRS performed in Iceland. A prospective study of 16 consecutive patients who underwent bilateral LVRS through median sternotomy between January 1996 and December 2008. All patients had disabling dyspnea, lung hyperinflation, and emphysema with upper lobe predominance. Preoperatively all patients underwent pulmonary rehabilitation. Spirometry, lung volumes, arterial blood gases and exercise capacity were measured before and after surgery. Mean follow-up time was 8.7 years. Mean age was 59.2 ± 5.9 years. All patients had a history of heavy smoking. There was no perioperative mortality and survival was 100%, 93%, and 63% at 1, 5, and 10 years, respectively. The forced expiratory volume in 1 second (FEV1) and the forced vital capacity (FVC) improved significantly after surgery by 35% (p<0.001) and 14% (p<0.05), respectively. The total lung capacity, residual volume and partial pressure of CO2 also showed statistically significant improvements but exercise capacity, O2 consumption and diffusing capacity of the lung for CO did not change. Prolonged air leak (≥ 7 days) was the most common complication (n=7). Five patients required reoperation, most commonly for sternal dehiscence (n=4). In this small prospective study, FEV1 and FVC increased and lung volumes and PaCO2 improved after LVRS. Long term survival was satisfactory although complications such as reoperations for sternal dehiscence were common and hospital stay therefore often prolonged.

Unusual Development of Iatrogenic Complex, Mixed Biliary and Duodenal Fistulas Complicating Roux-en-Y Antrectomy for Stenotic Peptic Disease of the Supraampullary Duodenum Requiring Whipple Procedure: An Uncommon Clinical Dilemma.

Complex fistulas of the duodenum and biliary tree are severe complications of gastric surgery. The association of duodenal and major biliary fistulas occurs rarely and is a major challenge for treatment. They may occur during virtually any kind of operation, but they are more frequent in cases complicated by the presence of difficult duodenal ulcers or cancer, with a mortality rate of up to 35%. Options for treatment are many and range from simple drainage to extended resections and difficult reconstructions. Conservative treatment is the choice for well-drained fistulas, but some cases require reoperation. Very little is known about reoperation techniques and technical selection of the right patients. We present the case of a complex iatrogenic duodenal and biliary fistula. A 42-year-old Caucasian man with a diagnosis of postoperative peritonitis had been operated on 3 days earlier; an antrectomy with a Roux-en-Y reconstruction for stenotic peptic disease was performed. Conservative treatment was attempted with mixed results. Two more operations were required to achieve a definitive resolution of the fistula and related local complications. The decision was made to perform a pancreatoduodenectomy with subsequent reconstruction on a double jejunal loop. The patient did well and was discharged on postoperative day 17. In our experience pancreaticoduodenectomy may be an effective treatment of refractory and complex iatrogenic fistulas involving both the duodenum and the biliary tree.

Objective To examine the reasons for practice variation in the treatment of displaced femoral neck fractures. Design A survey, asking surgeons to choose either hemiarthroplasty or internal fixation for 2 different female patients with a displaced femoral neck fracture. Setting The Canadian Orthopaedic Association Meeting, Halifax, May 1995. Patients The scenario in the first patient was of an independent 70-year-old woman with no pre-existing medical conditions. The scenario in the second patient was of a housebound 84-year-old woman with co-morbidity. Main outcome measures Proportion of surgeons choosing either hemiarthroplasty or internal fixation for each case scenario. Distribution of reasons to explain the treatment decision. Results Ninety-nine surgeons responded. For the case of the 70-year-old woman, 47% chose hemiarthroplasty and 53% chose internal fixation (p = 0.60), and for the 84-year-old woman, 96% chose hemiarthroplasty. These findings were consistent within the subgroups of teaching surgeons and community practice surgeons. Surgeons with 10 years or less of practice tended to favour hemiarthroplasty whereas those with more than 15 years’ practice favoured internal fixation. Important reasons for treatment choice were avoidance of reoperation in the hemiarthroplasty group (85%) and better hip function in the fixation group (83%), durability (83%) and ease of revision (77%). Conclusion The surgeon’s interpretation of the importance of reoperation and function underlies the differences in treatment decision regarding the management of femoral neck fractures in elderly patients.

The first Björk-Shiley convexoconcave (BSCC) prosthetic heart valves were implanted in 1978. The 25th anniversary provided a stimulus to summarize the research data relevant to BSCC valve fracture, patient management, and current clinical options. Published and unpublished data on the risks of BSCC valve fracture and replacement were compiled, and strategies for identifying candidates for prophylactic valve reoperation were summarized. By December 2003, outlet strut fractures (OSFs), often with fatal outcomes, had been reported in 633 BSCC valves (0.7% of 86,000 valves implanted). Fractures still continue to occur, but average rates of OSFs in 60 degrees valves are now <0.1% per year. OSF risk varies markedly by valve characteristics, especially valve angle and size, with weaker effects associated with other manufacturing variables. OSF risks are mildly lower among women than men but decline sharply with advancing age. The risks of valve replacement typically greatly exceed those of OSF. By comparing individualized estimated risks of OSF versus valve replacement, guidelines have been developed to identify the small percentage of BSCC patients (mostly younger men) who would be expected to have a gain in life expectancy should reoperative surgery be performed. Twenty-five years after the initial BSCC valve implants, fractures continue to occur. Continued monitoring of BSCC patients is needed to track and quantify risks and enable periodic updating of guidelines for patients and their physicians.

There is conflicting evidence about the merits of mobile bearings in total knee replacement, partly because most randomised controlled trials (RCTs) have not been adequately powered. We report the results of a multicentre RCT of mobile versus fixed bearings. This was part of the knee arthroplasty trial (KAT), where 539 patients were randomly allocated to mobile or fixed bearings and analysed on an intention-to-treat basis. The primary outcome measure was the Oxford Knee Score (OKS) plus secondary measures including Short Form-12, EuroQol EQ-5D, costs, cost-effectiveness and need for further surgery. There was no significant difference between the groups pre-operatively: mean OKS was 17.18 (sd 7.60) in the mobile-bearing group and 16.49 (sd 7.40) in the fixed-bearing group. At five years mean OKS was 33.19 (sd 16.68) and 33.65 (sd 9.68), respectively. There was no significant difference between trial groups in OKS at five years (-1.12 (95% confidence interval -2.77 to 0.52) or any of the other outcome measures. Furthermore, there was no significant difference in the proportion of patients with knee-related re-operations or in total costs. In this appropriately powered RCT, over the first five years after total knee replacement functional outcomes, re-operation rates and healthcare costs appear to be the same irrespective of whether a mobile or fixed bearing is used.

From 1973 through 1987, 155 radioisotope-powered nuclear pacemakers were implanted in 132 patients at the Newark Beth Israel Medical Center. The longevity of the first 15 devices, all of which were fixed-rate (VOO) pacemakers, was significantly better than that of 15 lithium-chemistry demand (VVI) pacemakers used as control devices (p = 0.0002). Of the entire cohort of 155 nuclear pacemakers, 136 were VVI devices and 19 were VOO units. The patients with VOO pacemakers needed reoperations more often than did those with VVI pacemakers, chiefly for mode change (p less than 0.001). Power-source failure was observed in only 1 case,more » but 47 nuclear pacemakers were removed for other reasons, including component malfunction (15 units), mode change (12 units), high pacing thresholds (8 units) and lead or connector problems (5 units). The actuarial survival at 15 years was 99% for power sources and 82% for the entire pacing systems (pulse generators plus leads). The frequency of malignancy was similar to that of the population at large and primary tumor sites were randomly distributed. Deaths most commonly were due to cardiac causes (68%). Thus, nuclear pacemakers are safe and reliable and their greater initial cost appears to be offset by their longevity and the resulting decrease in the frequency of reoperations. It is reasonable to suggest that further use be made of long-lasting nuclear power sources for modern pacemakers and other implantable rhythm-management devices.« less

Pannus formation after aortic valve replacement is not common, but obstruction due to chronic pannus is one of the most serious complications of valve replacement. The causes of pannus formation are still unknown and effective preventive methods have not been fully elucidated. We reviewed our clinical experience of all patients who underwent reoperation for prosthetic aortic valve obstruction due to pannus formation between 1973 and 2004. We compared the initial 18-year period of surgery, when the Björk-Shiley tilting-disk valve was used, and the subsequent 13-year period of surgery, when the St. Jude Medical valve was used. Seven of a total of 390 patients (1.8%) required reoperation for prosthetic aortic valve obstruction due to pannus formation. All seven patients were women; four patients underwent resection of the pannus and three patients needed replacement of the valve. The frequency of pannus formation in the early group was 2.4% (6/253), whereas it was 0.73% (1/137) in the late group (P < 0.05). Pannus was localized at the minor orifice of the Björk-Shiley valve in the early group and turbulent transvalvular blood flow was considered to be one of the important factors triggering its growth. We also consider that small bileaflet valves have the possibility of promoting pannus formation and that the implantation of a larger prosthesis can contribute to reducing the occurrence of pannus.

Acute dysfunction of mechanical aortic valve prostheses is a life-threatening adverse event. Pannus overgrowth, which is fibroelastic hyperplasia originating from the periannular area, is one cause of dysfunction. The aim of this study was to determine the annual incidence of readmittance resulting from acute obstruction caused by pannus during 30 years of observation in patients with Medtronic-Hall aortic valve prostheses and to analyze the risk factors associated with pannus development. From 1982 to 2004, 1,187 patients in our department underwent aortic valve replacement with Medtronic-Hall mechanical monoleaflet valve prostheses. As of December 31, 2012, 27 of these patients (2.3%) had presented with acute valve dysfunction caused by pannus obstruction. The annual incidence of pannus was 0.7 per 1,000. The median time from the primary operation to prosthetic dysfunction was 11.1 years (range, 1.2 to 26.8 years). Of the 20 patients who underwent reoperation, 2 died. Seven patients died before reoperation. Women had a higher risk for the development of obstructing pannus, and patients with pannus obstruction were younger. Valve size was not an independent risk factor. Women and younger patients are at higher risk for pannus development. When acute dysfunction by pannus is suspected in a mechanical aortic valve, an immediate echocardiogram and an emergency aortic valve replacement should be carried out because of the potential of a fatal outcome.

2017-02-01

The authors sought to ascertain the upper limits of secondary skull defect size amenable to autogenous reconstructions and to examine outcomes of a surgical series. Published data for autogenous and alloplastic skull reconstructions were also examined to explore associations that might guide treatment. A retrospective review of autogenously reconstructed secondary skull defects was undertaken. A structured literature review was also performed to assess potential differences in reported outcomes between autogenous bone and synthetic alloplastic skull reconstructions. Weighted risks were calculated for statistical testing. Ninety-six patients underwent autogenous skull reconstruction for an average defect size of 93 cm (range, 4 to 506 cm) at a mean age of 12.9 years. The mean operative time was 3.4 hours, 2 percent required allogeneic blood transfusions, and the average length of stay was less than 3 days. The mean length of follow-up was 28 months. There were no postoperative infections requiring surgery, but one patient underwent secondary grafting for partial bone resorption. An analysis of 34 studies revealed that complications, infections, and reoperations were more commonly reported with alloplastic than with autogenous reconstructions (relative risk, 1.57, 4.8, and 1.48, respectively). Autogenous reconstructions are feasible, with minimal associated morbidity, for patients with skull defect sizes as large as 500 cm. A structured literature review suggests that autogenous bone reconstructions are associated with lower reported infection, complication, and reoperation rates compared with synthetic alloplasts. Based on these findings, surgeons might consider using autogenous reconstructions even for larger skull defects. Therapeutic, IV.

Simultaneous Versus Sequential Ptosis and Strabismus Surgery in Children.

Revere, Karen E; Binenbaum, Gil; Li, Jonathan; Mills, Monte D; Katowitz, William R; Katowitz, James A

The authors sought to compare the clinical outcomes of simultaneous versus sequential ptosis and strabismus surgery in children. Retrospective, single-center cohort study of children requiring both ptosis and strabismus surgery on the same eye. Simultaneous surgeries were performed during a single anesthetic event; sequential surgeries were performed at least 7 weeks apart. Outcomes were ptosis surgery success (margin reflex distance 1 ≥ 2 mm, good eyelid contour, and good eyelid crease); strabismus surgery success (ocular alignment within 10 prism diopters of orthophoria and/or improved head position); surgical complications; and reoperations. Fifty-six children were studied, 38 had simultaneous surgery and 18 sequential. Strabismus surgery was performed first in 38/38 simultaneous and 6/18 sequential cases. Mean age at first surgery was 64 months, with mean follow up 27 months. A total of 75% of children had congenital ptosis; 64% had comitant strabismus. A majority of ptosis surgeries were frontalis sling (59%) or Fasanella-Servat (30%) procedures. There were no significant differences between simultaneous and sequential groups with regards to surgical success rates, complications, or reoperations (all p > 0.28). In the first comparative study of simultaneous versus sequential ptosis and strabismus surgery, no advantage for sequential surgery was seen. Despite a theoretical risk of postoperative eyelid malposition or complications when surgeries were performed in a combined manner, the rate of such outcomes was not increased with simultaneous surgeries. Performing ptosis and strabismus surgery together appears to be clinically effective and safe, and reduces anesthesia exposure during childhood.

Purpose  Patients with asplenia syndrome (AS) are likely to have upper gastrointestinal tract malformations such as hiatal hernia. This report discusses the treatment of such conditions. Methods  Seventy-five patients with AS underwent initial palliation in our institution between 1997 and 2013. Of these, 10 patients had hiatal hernia. Of the patients with hiatal hernia, 6 had brachyesophagus and 7 had microgastria. Results  Of the 10 patients with hiatal hernia, 9 underwent surgery in infancy (7 before Glenn operation, 2 after Glenn operation). Two underwent typical Toupet fundoplication, and the other 7 underwent atypical repair including reduction of the stomach. Two patients with atypical repair showed recurrence of hernia and required reoperation. Three patients required reoperation due to duodenal obstruction. Duodenal obstruction occurred due to preduodenal portal vein or abnormal vessels compressing the duodenum. Obstructive symptoms were not seen in any cases preoperatively. Conclusions  In patients with hiatal hernia, typical fundoplication is often difficult because most have concomitant brachyesophagus, microgastria, and hypoplasia of the esophageal hiatus. However, we should at least reduce the stomach to the abdominal cavity as early as possible to increase thoracic cavity volume and allow good feeding. Increasing the volume of the thoracic cavity thus makes Glenn and Fontan circulations more stable. Duodenal obstruction secondary to vascular anomalies is also common, so the anatomy in the area near the duodenum should be evaluated pre- and intraoperatively.

Background Resectional techniques are the established method of posterior mitral valve leaflet repair for degenerative disease; however, use of neochordae in a robotically assisted approach is gaining acceptance because of its versatility for difficult multi-segment disease. The purposes of this study were to compare the versatility, safety, and effectiveness of neochordal vs. resectional techniques for robotic posterior mitral leaflet repair. Methods From 12/2007 to 7/2010, 334 patients underwent robotic posterior mitral leaflet repair for degenerative disease by a resectional (n=248) or neochordal (n=86) technique. Outcomes were compared unadjusted and after propensity score matching. Results Neochordae were more likely to be used than resection in patients with two (28% vs. 13%, P=.002) or three (3.7% vs. 0.87%, P=.08) diseased posterior leaflet segments. Three resection patients (0.98%) but no neochordal patient required reoperation for hemodynamically significant systolic anterior motion (SAM). Residual mitral regurgitation (MR) at hospital discharge was similar for matched neochordal vs. resection patients (P=.14) (MR 0+, 82% vs. 89%; MR 1+, 14% vs. 8.2%; MR 2+, 2.3% vs. 2.6%; one neochordal patient had 4+ MR and was reoperated). Among matched patients, postoperative mortality and morbidity were similarly low. Conclusion Compared with a resectional technique, robotic posterior mitral leaflet repair with neochordae is associated with shorter operative times and no occurrence of SAM. The versatility, effectiveness, and safety of this repair make it a good choice for patients with advanced multi-segment disease. PMID:23103008

Liver transplantation is currently the standard of care for patients with end stage liver disease. However due to the cadaveric organ shortage, live donor liver transplantation (LDLT), has been recently introduced as a potential solution. We analyzed and support our initial experience with this procedure at USC. From September 1998 until July 2000, a total of 27 patients underwent LDLT at USC University Hospital and Los Angeles Children's Hospital. There were 12 children with the median age of 10 months (4-114) and 15 adults with the median age of 56 years (35-65). The most common indication for transplantation was biliary atresia for children and hepatitis C for adults. All donors did well postoperatively; the median postoperative stay was five days (5-7) for left lateral segmentectomy and seven days (4-12) for lobar donation. None of the donors required blood transfusion, re-operation or postoperative invasive procedure. However, five of them (18%) experienced minor complications. The survival rate in pediatric patients was 100% and only one graft was lost at nine months due to rejection. Two adult recipients died in the postoperative period, one from graft non-function and one from necrotizing fascitis. 37% of adult recipients experienced postoperative complications, mainly related to biliary reconstruction. Also 26% of the recipients underwent reoperation for some of these complications. LDLT is an excellent alternative to cadaveric transplantation with excellent results in the pediatric population. However, in adult patients it still carries a significant complication rate and it should be used with caution.

Subtotal cholecystectomy (SC) is a procedure that removes portions of the gallbladder when structures of the Calot triangle cannot be safely identified in "difficult gallbladders." To conduct a systematic review and meta-analysis to evaluate current studies and present an evidence-based assessment of the outcomes for the techniques available for SC. A literature search of the PubMed/MEDLINE (1954 to November 2013) and EMBASE (1974 to November 2013) databases was conducted. Search criteria included the words subtotal, partial, insufficient or incomplete, and cholecystectomy. Inclusion criteria were all randomized, nonrandomized, and retrospective studies with data on SC techniques and outcomes. Exclusion criteria were studies that reported data on SC along with other interventions (eg, cholecystostomy) without the possibility to discriminate results specific to SC. This systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The primary outcome of the study was the occurrence of common bild duct injury. Secondary outcomes included the occurrence of other SC-related morbidities, such as hemorrhage, subhepatic collection, bile leak, retained stones, postoperative endoscopic retrograde cholangiopancreatography, wound infection, reoperation, and mortality. Thirty articles were included. Subtotal cholecystectomy was typically performed using the laparoscopic technique (72.9%), followed by the open (19.0%) and laparoscopic converted to open (8.0%) techniques. The most common indications were severe cholecystitis (72.1%), followed by cholelithiasis in liver cirrhosis and portal hypertension (18.2%) and empyema or perforated gallbladder (6.1%). Morbidity rates were relatively low (postoperative hemorrhage, 0.3%; subhepatic collections, 2.9%; bile duct injury, 0.08%; and retained stones, 3.1%); the rate for bile leaks was higher (18.0%). Reoperations were necessary in 1.8% of the cases; the 30-day mortality rate was 0.4%. The laparoscopic approach produced less risk of subhepatic collection (odds ratio [OR], 0.4; 95% CI, 0.2-0.9), retained stones (OR, 0.5; 95% CI, 0.3-0.9), wound infection (OR, 0.07; 95% CI, 0.04-0.2), reoperation (OR, 0.5; 95% CI, 0.3-0.9), and mortality (OR, 0.2; 95% CI, 0.05-0.9) but more bile leaks (OR, 5.3; 95% CI, 3.9-7.2) compared with the open approach. Subtotal cholecystectomy is an important tool for use in difficult gallbladders and achieves morbidity rates comparable to those reported for total cholecystectomy in simple cases. The various technical differences appear to influence outcomes only for the laparoscopic approach.

Augmentation enterocystoplasty and appendicovesicostomy are complex pediatric urologic procedures. Although there is literature identifying long-term outcomes in these patients, the reporting of short-term postoperative outcomes has been limited by small numbers of cases and lack of prospective data collection. Here we report 30-day outcomes from the first nationally based, prospectively assembled cohort of pediatric patients undergoing these procedures. To determine 30-day complication, readmission and reoperation after augmentation enterocystoplasty and appendicovesicostomy in a large national sample of pediatric patients, and to explore the association between preoperative and intraoperative characteristics and occurrence of any 30-day event. We queried the 2012 and 2013 American College of Surgeons National Surgical Quality Improvement Program Pediatric database (ACS-NSQIPP) for all patients undergoing augmentation enterocystoplasty and/or appendicovesicostomy. Surgical risk score was classified on a linear scale using a validated pediatric-specific comorbidity score. Intraoperative characteristics and postoperative 30-day events were reported from prospectively collected data. A composite measure of complication, readmission and/or reoperation was used as primary outcome for the multivariate logistic regression. There were 461 patients included in the analysis: 245 had appendicovesicostomy, 97 had augmentation enterocystoplasty and 119 had both procedures. There were a total of 110 NSQIP complications seen in 87 patients. The most common complication was urinary tract infection (see Table for 30-day outcomes by patient). The composite measure of any 30-day event was seen in 27.8% of the cohort and this was associated with longer operative time, increased number of procedures done at time of primary surgical procedure and higher surgical risk score. The ACS-NSQIPP provides a tool to examine short-term outcomes for these complex urologic procedures that has not been possible before. Although ACS-NSQIP has been used extensively in the adult surgical literature to identify rates of complications, and to determine predictors of readmission and adverse events, its use in pediatric surgery is new. As in the adult literature, the goal is for standardization of practice and transparency in reporting outcomes that may lead to reduction in morbidity and mortality. In this cohort, any 30-day event is seen in almost 30% of the patients undergoing these urologic procedures. Operative time, number of concurrent procedures and higher surgical risk score all are associated with higher odds of the composite 30-day event of complication, readmission and/or reoperation. These data can be useful in counseling patients and families about expectations around surgery and in improving outcomes. Copyright © 2015 Journal of Pediatric Urology Company.

Although there have been reports of single-surgeon outcomes with highly cohesive, form-stable silicone gel implants in women undergoing primary breast augmentation, there has been only one study published that compares the outcomes between the Allergan 410 and the Mentor CPG devices. The goal of the study is to compare outcomes in each cohort and to determine if quality systems and processes would have an impact on lowering the surgical revision rate, as compared to published reports for round gel implants and form-stable implants. Patients selected for the study were required to meet predefined inclusion criteria and general indications for breast augmentation. All subjects were treated uniformly with extensive informed consent prior to surgery. The entire process of breast augmentation (patient assessment, informed consent, the surgical procedure itself and postoperative instructions) was identical between the two groups. Patients were not randomized, as the studies did not start at the same time. The process for management of each patient was based on adaptation of the Toyota Production System and Lean Manufacturing, with emphasis on achieving operational excellence in the use of planning templates for surgery, including accurate management of patient expectations regarding size outcome. Outcomes data included physical breast measurements, quality of life metrics, and patient/surgeon satisfaction assessment. Adverse events were compared against published data for breast implants. Follow-up ranged between 20-77 months (Allergan 410) and 16-77 months (Mentor CPG). The outcome data indicate that these devices produce natural-appearing breasts with extremely low aggregate reoperation rate (4.2%). Only 0.8% of the reoperations were attributable to surgeon-related factors. There were no reoperations to correct mismanaged size expectations during the course of each study. There were 13 pregnancies and no difficulties with lactation were reported. Rippling (lateral/medial, palpable and/or visible) was encountered in both cohorts. The Mentor CPG cohort had a fivefold greater incidence of rippling (37.3% versus 7.6% in Allergan 410 cohort). This was highly statistically significant (P < .001). Provided that there is adherence to core principles and avoidance of errors in planning, patient expectations, and surgery, highly cohesive, form-stable breast implants can deliver excellent long term outcomes in primary breast augmentation in a diverse patient population. The impact of quality processes such as Toyota Production System and Lean Manufacturing was substantive in delivering operational excellence in primary breast augmentation.

Mitral valve replacement with either a bioprosthetic or a mechanical valve is the treatment of choice for severe mitral stenosis. However, choosing a valve implant type is still a subject of debate. This study aimed to evaluate and compare the early and late outcomes of mitral valve replacement [mechanical (MMV) vs. bioprosthetic (BMV)] for severe mitral stenosis. A retrospective cohort study was performed on data involving mitral stenosis patients who have undergone mitral valve replacement with either BMV (n = 50) or MMV (n = 145) valves from 1999 to 2012. Data were collected from the patients' records and follow-up through telephone calls. Data were analyzed for early and late mortality, New York Heart Association (NYHA) functional classes, stroke, pre- and postoperative echocardiographic findings, early and late valve-related complications, and survival. Chi-square test, logistic regression, Kaplan-Meier curve, and dependent proportions tests were some of the tests employed in the analysis. A total of 195 patients were included in the study with a 30-day follow-up echocardiogram available for 190 patients (97.5%), while 103 (53%) were available for follow-up over the telephone. One patient died early postoperatively; twelve patients died late in the postoperative period, six in the bioprosthesis group and six in the mechanical group. The late mortality had a significant association with postoperative stroke (p < 0.001) and postoperative NYHA Classes III and IV (p = 0.002). Postoperative NYHA class was significantly associated with age (p = 0.003), pulmonary disease (p = 0.02), mitral valve implant type (p = 0.01), and postoperative stroke (p = 0.02); 14 patients had strokes in the mechanical (9) and in the bioprosthetic (5) groups. NYHA classes were significantly better after the replacement surgeries (p < 0.001). BMV were significantly associated with worse survival (p = 0.03), worse NYHA postoperatively (p = 0.01), and more reoperations (p = 0.006). Survival was significantly better with MMV (p = 0.03). When the two groups were matched for age and mitral regurgitation, the analysis revealed that BMV were significantly associated with reoperations (p = 0.02) but not significantly associated with worse survival (p = 0.4) or worse NYHA (p = 0.4). MMV replacement in mitral stenosis patients is associated with a lower reoperation rate, but there was no difference in survival compared with BMV replacement.

Mitral valve (MV) repairs have been performed in paediatric patients with congenital MV stenosis. However, congenital MV stenosis lesions are a heterogeneous group of lesions, and their repair remains challenging. From March 1999 to September 2014, MV repair was performed in 22 patients with congenital MV stenosis. The median age was 10.3 months (ranging from 22 days to 9.1 years), and the mean body weight was 7.9 ± 4.0 kg at the time of the operation. Multiple-level left-side heart obstructions were present in 9 (45%) patients. The main aetiology of the mitral stenosis was a supravalvular mitral ring in 8 patients, valvular stenosis in 4 patients, a parachute deformity of the papillary muscles in 4 patients and other abnormal papillary muscles in 6 patients. The mean MV pressure gradient improved from 10.4 ± 3.9 mmHg to 3.4 ± 1.7 mmHg after MV repair (n = 18, P < 0.0001). The mean follow-up duration was 6.7 ± 5.4 years. One patient died postoperatively due to septic shock. Four patients required a second operation (2 patients for mitral stenosis, 1 patient for left ventricular outflow tract obstruction and mitral stenosis and 1 patient for mitral regurgitation). Among them, 2 patients died: 1 patient died due to cardiopulmonary bypass weaning failure and another patient died due to multiple cerebral infarcts. At the last follow-up, the mean MV pressure gradient was 4.5 ± 3.1 mmHg for all patients who did not have reoperation, and moderate or greater mitral insufficiency was detected in 3 patients. At 10 years, the survival rate was 85.9 ± 7.6%, and the freedom from reoperation rate was 77.5 ± 10.1%. In the log-rank test, MV repair in the neonate was associated with mortality (P = 0.010), and presentation of mitral insufficiency was associated with reoperation (P = 0.003). MV repair in paediatric patients with congenital mitral stenosis showed acceptable results. The follow-up echocardiogram also revealed satisfactory results. Close follow-up is necessary to detect the development of postoperative mitral stenosis or regurgitation. © The Author 2017.

Objective Morbidity associated with surgical site infection (SSI) following nonshunt pediatric neurosurgical procedures is poorly understood. The purpose of this study was to analyze acute morbidity and mortality associated with SSI after nonshunt pediatric neurosurgery using a nationwide cohort. Methods The authors reviewed data from the American College of Surgeons National Surgical Quality Improvement Program Pediatric (NSQIP-P) 2012–2014 database, including all neurosurgical procedures performed on pediatric patients. Procedures were categorized by Current Procedural Terminology (CPT) codes. CSF shunts were excluded. Deep and superficial SSIs occurring within 30 days of an index procedure were identified. Deep SSIs included deep wound infections, intracranial abscesses, meningitis, osteomyelitis, and ventriculitis. The following outcomes occurring within 30 days of an index procedure were analyzed, along with postoperative time to complication development: sepsis, wound disruption, length of postoperative stay, readmission, reoperation, and death. Results A total of 251 procedures associated with a 30-day SSI were identified (2.7% of 9296 procedures). Superficial SSIs were more common than deep SSIs (57.4% versus 42.6%). Deep SSIs occurred more frequently after epilepsy or intracranial tumor procedures. Superficial SSIs occurred more frequently after skin lesion, spine, Chiari decompression, craniofacial, and myelomeningocele closure procedures. The mean (± SD) postoperative length of stay for patients with any SSI was 9.6 ± 14.8 days (median 4 days). Post-SSI outcomes significantly associated with previous SSI included wound disruption (12.4%), sepsis (15.5%), readmission (36.7%), and reoperation (43.4%) (p < 0.001 for each). Post-SSI sepsis rates (6.3% vs 28.0% for superficial versus deep SSI, respectively; p < 0.001), wound disruption rates (4.9% vs 22.4%, p < 0.001), and reoperation rates (23.6% vs 70.1%, p < 0.001) were significantly greater for patients with deep SSIs. Postoperative length of stay in patients discharged before SSI development was not significantly different for deep versus superficial SSI (4.2 ± 2.7 vs 3.6 ± 2.4 days, p = 0.094). No patient with SSI died within the first 30 days after surgery. Conclusions Thirty-day SSI is associated with significant 30-day morbidity in pediatric patients undergoing nonshunt neurosurgery. Rates of SSI-associated complications are significantly lower in patients with superficial infection than in those with deep infection. There were no cases of SSI-related mortality within 30 days of the index procedure. PMID:28186474

Degenerative mitral valve repair rates remain highly variable, despite established benefits of repair over replacement. The contribution of surgeon-specific factors is poorly defined. This study evaluated the influence of surgeon case volume on degenerative mitral valve repair rates and outcomes. A mandatory New York State database was queried and 5,475 patients were identified with degenerative mitral disease who underwent mitral valve operations between 2002 and 2013. Mitral repair rates, mitral reoperations within 12 months of repair, and survival were analyzed using multivariable Cox modeling and restricted cubic spline function. Median annual surgeon volume of any mitral operations was 10 (range 1 to 230), with a mean repair rate of 55% (n = 20,797 of 38,128). In the subgroup of patients with degenerative disease, the mean repair rate was 67% (n = 3,660 of 5,475), with a range of 0% to 100%. Mean repair rates ranged from 48% (n = 179 of 370) for surgeons with total annual volumes of ≤10 mitral operations to 77% (n = 1,710 of 2,216) for surgeons with total annual volumes of >50 mitral operations (p < 0.001). Higher total annual surgeon volume was associated with increased repair rates of degenerative mitral valve disease (adjusted odds ratio [OR]: 1.13 for every additional 10 mitral operations; 95% confidence interval [CI]: 1.10 to 1.17; p < 0.001); a steady decrease in reoperation risk until 25 total mitral operations annually; and improved 1-year survival (adjusted hazard ratio: 0.95 for every additional 10 operations; 95% CI: 0.92 to 0.98; p = 0.001). For surgeons with a total annual volume of ≤25 mitral operations, repair rates were higher (63.8%; n = 180 of 282) if they operated in the same institution as a surgeon with total annual mitral volumes of >50 and degenerative mitral valve repair rates of >70%, compared with surgeons operating in the other institutions (51.3%; n = 580 of 1,130) (adjusted OR: 1.79; 95% CI: 1.24 to 2.60; p < 0.001). This study suggests that individual surgeon volume is a determinant of not only mitral repair rates, but also freedom from reoperation, and survival. The data from this study support the guideline's concept of reference referral to experienced mitral surgeons to improve outcomes in patients with degenerative mitral valve disease. Copyright © 2017.

In most treatment algorithms, osteochondral allograft (OCA) transplantation is regarded as an alternative salvage procedure when other, previous reparative treatments have failed. To compare the outcomes of a retrospective matched-pair cohort of (1) primary OCA transplantation and (2) OCA transplantation after failure of previous subchondral marrow stimulation. Cohort study; Level of evidence, 3. An OCA database was used to identify 46 knees that had OCA transplantation performed as a primary treatment (group 1) and 46 knees that underwent OCA transplantation after failure of previous subchondral marrow stimulation (group 2). All patients had a minimum of 2 years' follow-up. Patients in each group were matched for age (±5 years), diagnosis (osteochondral lesion, degenerative chondral lesion, traumatic chondral injury), and graft size (small, <5 cm2; medium, 5-10 cm2; large, >10 cm2). The groups had similar body mass indexes, sex distributions, and graft locations (femoral condyle, patella, and trochlea. The number and type of further surgeries after the OCA transplantation were assessed; failure was defined as any reoperation resulting in removal of the graft. Functional outcomes were evaluated by use of the modified Merle d'Aubigné-Postel (18-point) scale, International Knee Documentation Committee (IKDC) subjective knee evaluation form, Knee injury and Osteoarthritis Outcomes Score (KOOS), and the Knee Society function (KS-F) scale. Patient satisfaction, according to a 5-point scale from "extremely satisfied" to "dissatisfied," was recorded at the latest follow-up. Eleven of 46 knees (24%) in group 1 had reoperations, compared with 20 of 46 knees (44%) in group 2 (P = .04). The OCA was classified as a failure in 5 knees (11%) in group 1 and 7 knees (15%) in group 2 (P = .53). At 10 years of follow-up, survivorship of the graft was 87.4% and 86% in groups 1 and 2, respectively. Both groups showed improvement in pain and function on all subjective scores from preoperatively to the latest follow-up (all P < .001). Results showed that 87% of patients in group 1 and 97% in group 2 were "satisfied" or "extremely satisfied" with the OCA transplantation. Favorable results were shown in both groups with significant improvement of functional scores and excellent survivorship. Despite the higher reoperation rate in the previously treated group, previous subchondral marrow stimulation did not adversely affect the survivorship and functional outcome of OCA transplantation. © 2015 The Author(s).

There is a paucity of published data regarding the management of osteochondritis dissecans (OCD) lesions of the patellofemoral joint in children and adolescents. To evaluate the functional outcomes of surgical management of OCD lesions of the patella and trochlea in children and adolescents. Secondary aims included elucidating predictors for higher functional outcomes and determining complication rates, surgical satisfaction, and ability to return to sports. Case series; Level of evidence, 4. Patients aged 18 years and younger who were surgically treated for OCD of the patella or trochlea were identified. Charts were queried to record patient/lesion data, surgical procedure, results, and complications. Pre- and postoperative imaging was reviewed. Patients were asked to complete a follow-up athletic questionnaire and a Pediatric International Knee Documentation Committee (Pedi-IKDC) questionnaire. Statistical analysis was conducted to look for predictors for reoperation, residual pain, ability to return to sports, and lower Pedi-IKDC scores. A total of 26 children (9 females, 17 males, 3 with bilateral lesions; thus, 29 lesions) were identified. The mean age was 14.7 years (range, 9-18, years), 21 of the 29 knees with lesions (72%) had open physes, and median follow-up was 3.8 years (range, 1-9 years). The most common location was the trochlea (17/29 lesions; 59%). Twenty-two lesions (76%) underwent transarticular drilling (n = 14) or drilling with fixation (n = 8), while 7 underwent excision and marrow stimulation. Four patients (14%) required unplanned reoperation. Internal fixation was predictive of reoperation (odds ratio [OR] = 8.7; 95% CI, 2.8-26.9; P = .04). At final follow-up, 14 knees (48%) were pain free, and 14 (48%) had mild residual pain. Female sex was predictive of residual pain (OR, 9; 95% CI, 2-56; P = .02). Twenty-two patients (85%) returned to sports. Longer duration of preoperative pain negatively affected return to sports (OR, 0.32; 95% CI, 0.05-0.97; P = .04). On postoperative MRI, the lesion appeared completely healed in 2 cases (18%) and partially healed in 9 cases (82%). All 15 survey respondents were satisfied with surgery. The mean Pedi-IKDC score was 82.4 ± 17.8 (range, 40.2-100). Surgical treatment of patellofemoral OCD in children and adolescents produces a high rate of satisfaction and return to sports. Female sex, prolonged duration of symptoms, and internal fixation may be associated with worse outcomes. © 2015 The Author(s).

Operative treatment of sternal fractures.

Four patients with displaced sternal fractures complained of intractable pain following road traffic accidents. They all had bone deformities, but only one had associated traumatic injuries. All patients underwent operative reduction and fixation of the fractured sternum using a T-shaped compression-tension stainless steel plate and screws. Pain relief was often dramatic and all patients progressed to sternal union. None required reoperation. No infections occurred. Two plates have subsequently been removed. On follow-up, all patients had excellent results. Sternal plating, which is based on the tension-band principle, is an effective treatment for displaced sternal fractures.

Wound infections after transplant nephrectomy were analyzed retrospectively. When prophylactic antibiotics were not used, 20% of the closed nephrectomy wounds became infected. Eighty-one percent of the infections were due to staphylococcal organisms. Wounds containing a preexisting focus of infection or those reoperated on more than once within a month prior to nephrectomy are at such high risk for infection that these wounds should be left open for secondary healing. With the use of prophylactic cefazolin sodium, in the immediate preoperative and postoperative period, no wound infections have occurred in 18 closed transplant nephrectomy wounds.

The purpose of this study was to identify significant, independent factors that predicted 6 month patient and graft survival after pediatric liver transplantation. The Studies of Pediatric Liver Transplantation (SPLIT) is a multicenter database established in 1995, of currently more than 4000 US and Canadian children undergoing liver transplantation. Previous published analyses from this data have examined specific factors influencing outcome. This study analyzes a comprehensive range of factors that may influence outcome from the time of listing through the peri- and postoperative period. A total of 42 pre-, peri- and posttransplant variables evaluated in 2982 pediatric recipients of a first liver transplant registered in SPLIT significant at the univariate level were included in multivariate models. In the final model combining all baseline and posttransplant events, posttransplant complications had the highest relative risk of death or graft loss. Reoperation for any cause increased the risk for both patient and graft loss by 11 fold and reoperation exclusive of specific complications by 4 fold. Vascular thromboses, bowel perforation, septicemia, and retransplantation, each independently increased the risk of patient and graft loss by 3 to 4 fold. The only baseline factor with a similarly high relative risk for patient and graft loss was recipient in the intensive care unit (ICU) intubated at transplant. A significant center effect was also found but did not change the impact of the highly significant factors already identified. We conclude that the most significant factors predicting patient and graft loss at 6 months in children listed for transplant are posttransplant surgical complications.

This study was conceived to describe the evolution of aortic dimensions in patients with moderate post-stenotic ascending aorta dilation (50 to 59 mm) submitted to aortic valve replacement (AVR) alone. The appropriate treatment of post-stenotic ascending aorta dilation has been poorly investigated. Ninety-three patients affected by severe isolated calcific aortic valve stenosis in the tricuspid aortic valve accompanied by moderate dilation of the ascending aorta (50 to 59 mm) were submitted to AVR only. All patients were followed for a mean of 14.7 ± 4.8 years by means of periodic clinical evaluations and echocardiography and tomography scans of the thorax. Operative mortality was 1.0% (1 patient). During the follow-up, 16 patients died and 2 had to be reoperated for valve dysfunction. No patients experienced acute aortic events (rupture, dissection, pseudoaneurysm), and no patient had to be reoperated on the aorta. There was not a substantial increase in aortic dimensions: mean aortic diameter was 57 ± 11 mm at the end of the follow-up versus 56 ± 02 mm pre-operatively (p = NS). The mean ascending aorta expansion rate was 0.3 ± 0.2 mm/year. In the absence of connective tissue disorders, AVR alone is sufficient to prevent further aortic expansion in patients with moderate post-stenotic dilation of the ascending aorta. Aortic replacement can probably be reserved for patients with a long life expectancy. Copyright © 2011 American College of Cardiology Foundation. Published by Elsevier Inc. All rights reserved.

2015-11-01

To investigate hypospadias' prevalence and trends, rate of surgical repairs and post-repair complications in an Australian population. Hypospadias cases were identified from all live-born infants in New South Wales, Australia, during the period 2001-2010, using routinely collected birth and hospital data. Prevalence, trends, surgical procedures or repairs, hospital admissions and complications following surgery were evaluated. Risk factors for reoperation and complications were assessed using multivariate logistic regression. There were 3186 boys with hypospadias in 2001-2010. Overall prevalence was 35.1 per 10,000 live births and remained constant during the study period. Proportions of anterior, middle, proximal and unspecified hypospadias were 41.3%, 26.2%, 5.8% and 26.6%, respectively. Surgical procedures were performed in 1945 boys (61%), with 1718 primary repairs. The overall post-surgery complication rate involving fistulas or strictures was 13%, but higher (33%) for proximal cases. Complications occurred after 1 year post-repair in 52.3% of cases and up to 5 years. Boys with proximal or middle hypospadias were at increased risk of reoperation or complications, but age at primary repair did not affect the outcome. One in 285 infants were affected with hypospadias, 60% required surgical repair or correction and one in eight experienced complications. The frequency of late complications would suggest that clinical review should be maintained for >1 year post-repair. Published by the BMJ Publishing Group Limited.

Patients with diabetes are at increased risk of wound complications after open reduction and internal fixation of unstable ankle fractures. A fibular nail avoids large surgical incisions and allows anatomical reduction of the mortise. We retrospectively reviewed the results of fluoroscopy-guided reduction and percutaneous fibular nail fixation for unstable Weber type B or C fractures in 24 adult patients with type 1 or type 2 diabetes. The re-operation rate for wound dehiscence or other indications such as amputation, mortality and functional outcomes was determined. Two patients developed lateral side wound infection, one of whom underwent wound debridement. Three other patients required re-operation for removal of symptomatic hardware. No patient required a below-knee amputation. Six patients died during the study period for unrelated reasons. At a median follow-up of 12 months (7 to 38) the mean Short Form-36 Mental Component Score and Physical Component Score were 53.2 (95% confidence intervals (CI) 48.1 to 58.4) and 39.3 (95% CI 32.1 to 46.4), respectively. The mean Visual Analogue Score for pain was 3.1 (95% 1.4 to 4.9). The mean Ankle Osteoarthritis Scale total score was 32.9 (95% CI 16.0 to 49.7). Fluoroscopy-guided reduction and fibular nail fixation of unstable ankle fractures in patients with diabetes was associated with a low incidence of wound and overall complications, while providing effective surgical fixation.

Long-term steroid therapy may predispose to increased perioperative morbidity in patients undergoing surgery with bowel anastomoses. The aim of our study was to review our data to determine if the steroid dosage is associated with the incidence of early complications after bowel resection in patients with prolonged steroid therapy for Crohńs disease (CD). Altogether, 397 patients underwent bowel resection with primary intestinal anastomoses for CD between 1982 and 2000 in our institution. The mortality and morbidity rates, anastomotic leakage, wound infections, intraabdominal abscesses, reoperation rate, and length of postoperative hospitalization in patients who were having high-dose (>/= 20 mg of prednisolone per day, n = 73) and low-dose (< 20 mg prednisolone per day, n = 146) steroid therapy for more than 1 month before surgery were compared with those of patients ( n = 177) who were not receiving steroids. Statistical analysis was performed using Fisher's exact test and Student's t-test, with p < 0.05 considered significant. The three groups were similar in terms of gender, duration since first diagnosis, American Society of Anesthesiologists classification, and obesity. Mortality, morbidity, anastomotic leakage, wound infections, intraabdominal abscesses, reoperation rate, and average postoperative stay were not statistically different in patients with high-dose, low-dose, or no steroid therapy. The only factor associated with increased morbidity was a low preoperative hemoglobin level. Our results demonstrate that, in patients who are undergoing bowel resection for CD, even high-dose prolonged preoperative systemic steroid therapy is not associated with increased postoperative complications.

Fiscal constraints are driving shorter hospital lengths of stay. Outpatient primary cleft lip surgery has been shown to be safe, but outpatient primary cleft palate surgery remains controversial. This study evaluates outcomes following outpatient versus inpatient primary cleft lip and palate surgery. The American College of Surgeons National Surgical Quality Improvement Program Pediatric database was used to identify patients undergoing primary cleft lip and palate surgery between 2012 and 2015. Patient clinical factors and 30-day complications were compared for outpatient versus inpatient primary cleft lip and palate surgery. Univariate and multivariate analyses were performed. Three thousand one hundred forty-two patients were included in the primary cleft lip surgery group and 4191 in the primary cleft palate surgery group. Patients in the cleft lip surgery group with structural pulmonary abnormalities had a significantly longer hospital length of stay (β, 4.94; p = 0.001). Patients undergoing outpatient surgery had a significantly higher risk of superficial (OR, 1.99; p = 0.01) and deep wound dehiscence (OR, 2.22; p = 0.01), and were at a significantly lower risk of reoperation (OR, 0.36; p = 0.04) and readmission (OR, 0.52; p = 0.02). Outpatient primary cleft lip surgery is safe and has a complication profile similar to that of inpatient surgery. Outpatient primary cleft palate surgery is common practice in many U.S. hospitals and has a significantly higher rate of wound complications, and lower rates of reoperation and readmission. In properly selected patients, outpatient palatoplasty can be performed safely. Therapeutic, III.

Background: Fast-track (FT) rehabilitation protocols have been shown to be successful in reducing both hospital stay and postoperative complications, as well as enhancing overall postoperative patient recovery. We are reporting the outcomes of our first group of patients undergoing colorectal surgery following the FT protocol. Patients and Methods: We performed a prospective study of patients, between January 1, 2007 and January 31, 2010, who underwent laparoscopic colorectal resections in accordance with the guidelines of FT rehabilitation protocol. Recovery parameters including time to removal of naso-gastric tube and urinary catheter, time to bowel function and to resume diet, and length of hospital stay were evaluated. Postoperative outcomes, that is, postoperative complications and mortality, reoperations, and readmissions were also studied. Results: A total of 71 patients, 30 women and 41 men, underwent FT rehabilitation for laparoscopic colorectal surgery. The mean age of the patients was 60 ± 16 years. The most common surgical procedures were right hemicolectomy 30% and anterior resection 27%. Liquid and regular diet were initiated on postoperative day 1.2 ± 0.4 and 2.1 ± 0.4, respectively. Overall postoperative morbidity was 8.5%. The mean length of stay was 4.4 ± 1.7 days, with only 3 readmissions. Forty-five patients fulfilled the FT care plan and were discharged on postoperative day 3. No reoperations or mortality were observed. Conclusions: FT rehabilitation results in favorable postoperative outcomes. Our data provides evidence and suggests that FT protocols should be implemented as a reliable method of preparation and recovery for laparoscopic colorectal surgery. PMID:25489207

The ideal age for correction of tetralogy of Fallot is still under discussion. The aim of this study was to analyze morbidity and mortality in patients who underwent early primary repair of tetralogy of Fallot at the age of less than 4 months and to assess whether neonates, who needed early repair within the first 4 weeks of life, faced an increased risk. From 1995 to 2006, 90 consecutive patients with tetralogy of Fallot and pulmonary stenosis underwent early primary repair. Patient charts were analyzed retrospectively for two groups: group A, 25 neonates younger than 28 days who needed early operation owing to duct-dependent pulmonary circulation or severe hypoxemia; and group B, 65 infants younger than 4 months of age who underwent elective early repair. There was no 30-day mortality; late mortality was 2% after a median follow-up time of 4.7 years. Seven of 88 patients (8%) needed reoperation and twelve of 88 patients (14%) needed reintervention. Groups A and B did not differ significantly in terms of intensive care unit stay, days of mechanical ventilation, overall hospital stay, major or minor complications, or reoperation. Significant differences were found in a more frequent use of a transannular patch (p = 0.045) and more reinterventions (p = 0.046) in group A. Early primary repair of tetralogy of Fallot can be performed safely and effectively in infants younger than 4 months of age and even in neonates younger than 28 days with duct-dependent pulmonary circulation or severe hypoxemia.

The Supra-Inframammary Fold Approach to Breast Augmentation: Avoiding a Double Bubble

PubMed Central

2017-01-01

Background: The inframammary incision for breast augmentation is commonly made at or below the existing inframammary fold (IMF) in an effort to keep the scar in the crease. In recent studies, surgeons inferiorly relocate the IMF, center the implant at nipple level, and attempt to secure the new IMF with sutures. The fascial attachments (also called ligaments) holding the IMF are released, risking a bottoming-out deformity or a double bubble. Methods: This retrospective study evaluated 160 consecutive women undergoing primary subpectoral breast augmentation. An incision was made 0.5–1.0 cm above the IMF. Dissection proceeded directly to the pectoralis margin, preserving IMF fascial attachments. The pectoralis origin was released from the lower sternum. Surveys were administered to obtain patient-reported outcome data. Ninety-eight patients (61%) participated. Results: Implants often appear high on the chest at early follow-up appointments but gradually settle. One patient (0.6%) developed a double bubble. No reoperations were needed for implant malposition. One patient had a mild animation deformity. There were no cases of symmastia. The mean result rating was 9.1/10. Four percent of surveyed patients found their implants too high; 8% found them too low. Ninety-two patients (94%) reported that their scars were well-hidden. Ninety-six women (98%) said that they would redo the surgery. Conclusions: A supra-IMF approach anticipates the normal descent of implants after augmentation. Scars remain hidden both in standing and supine positions. This method reduces the short-term risk of reoperation for implant malposition or a double bubble. PMID:28831352

No association between seniority of surgeon and postoperative recurrence of chronic subdural haematoma

Introduction Neurosurgical trainees should achieve competency in chronic subdural haematoma (CSDH) drainage at an early stage in training. The effect of surgeon seniority on recurrence following surgical drainage of CSDH was examined. Methods All CSDH cases performed at St George’s Hospital in London between March 2009 and March 2012 were analysed. Recurrence was defined as clinical deterioration with computed tomography evidence of CSDH requiring reoperation within six months. The following risk factors were considered: seniority of primary and supervising surgeons, timing of surgery (working hours, outside working hours), patient related factors (age, antiplatelets, warfarin) and operative factors (general vs local anaesthesia, burr holes vs craniotomy, drain use). For recurrent cases, we examined the distance of the cranial opening from the thickest part of the CSDH. Results A total of 239 patients (median age: 79 years, range: 33–98 years) had 275 CSDH drainage operations. The overall recurrence rate was 13.1%. The median time between the initial procedure and reoperation was 16 days (range: 1–161 days). The only statistically significant risk factor for recurrence was antiplatelets (odds ratio: 2.62, 95% confidence interval: 1.13–6.10, p<0.05). Warfarin, grade of surgeon, timing of surgery, type of anaesthesia, type of operation and use of drains were not significant risk factors. In 26% of recurrent CSDH cases, the burr holes or craniotomy flaps were placed with borderline accuracy. Conclusions CSDH drainage is a suitable case for neurosurgical trainees to perform without increasing the chance of recurrence. PMID:26492904

Recurrence of chronic subdural haematomas (CSDHs) after surgical drainage is a significant problem with rates up to 20%. This study focuses on determining factors predictive of haematoma recurrence and presents a scoring system stratifying recurrence risk for individual patients. Between the years 2005 and 2009, 331 consecutive patients with CSDHs treated with surgery were included in this study. Univariate and multivariate analyses were performed searching for risk factors of increased post-operative haematoma volume and haematoma recurrence requiring repeat drainage. We found a 12% reoperation rate. CSDH septation (seen on computed tomogram scan) was found to be an independent risk factor for recurrence requiring reoperation (p=0.04). Larger post-operative subdural haematoma volume was also significantly associated with requiring a second drainage procedure (p<0.001). Independent risk factors of larger post-operative haematoma volume included septations within a CSDH (p<0.01), increased pre-operative haematoma volume (p<0.01), and a greater amount of parenchymal atrophy (p=0.04). A simple scoring system for quantifying recurrence risk was created and validated based on patient age (< or ≥ 80 years), haematoma volume (< or ≥ 160 cc), and presence of septations within the subdural collection (yes or no). Septations within CSDHs are associated with larger post-operative residual haematoma collections requiring repeat drainage. When septations are clearly visible within a CSDH, craniotomy might be more suitable as a primary procedure as it allows greater access to a septated subdural collection. Our proposed scoring system combining haematoma volume, age, and presence of septations might be useful in identifying patients at higher risk for recurrence.

Sharing the opportunity cost among power companies to support hydropower-to-environment water transfers

Among the environmental impacts caused by dams, the alteration of flow regimes is one of the most critical to river ecosystems given its influence in long river reaches and its continuous pattern. Provided it is technically feasible, the reoperation of hydroelectric reservoir systems can, in principle, mitigate the impacts on degraded freshwater ecosystems by recovering some of the natural flow regime. The typical approach to implement hydropower-to-environment water transfers focuses on the reoperation of the dam located immediately upstream of the environmentally sensitive area, meaning that only one power station will bear the brunt of the benefits forgone for the power sector. By ignoring the contribution of upstream infrastructures to the alteration of the flow regime, the opportunity cost associated with the restoration of a flow regime is not equitably distributed among the power companies in the river basin, therefore slowing the establishment of environmental flow programs. Yet, there is no criterion, nor institutional mechanisms, to ensure a fair distribution of the opportunity cost among power stations. This paper addresses this issue by comparing four rules to redistribute the costs faced by the power sector when environmental flows must be implemented in a multireservoir system. The rules are based on the the installed capacity of the power plants, the live storage capacity of the reservoirs, the ratio between the incremental flows and the live storage capacity, and the extent of the storage services; that is, the volume of water effectively transferred by each reservoir. The analysis is carried out using the Parana River Basin (Brazil) as a case study.

The forehead, which occupies about one third of the face, is one of the major determinants of a feminine or masculine look. Various methods have been used for the augmentation of the forehead using autologous fat grafts or alloplastic materials. Methylmethacrylate (MMA) is the most appropriate material for augmentation of the forehead, and we have used an injection-molding technique with MMA to achieve satisfactory results. Under local anesthesia with intravenous (IV) sedation, an incision was made on the scalp and a meticulous and delicate subperiosteal dissection was then performed. MMA monomers and polymers were mixed, the dough was injected into the space created, and manual molding was performed along with direct inspection. This surgery was indicated for patients who wanted to correct an unattractive appearance by forehead augmentation. Every patient in this study visited our clinics 3 months after surgery to evaluate the results. We judged the postoperative results in terms of re-operation rates caused by the dissatisfaction of the patients and complications. During a 13-year period, 516 patients underwent forehead augmentation with MMA. With the injection-molding technique, the inner surface of the MMA implant is positioned close to the underlying frontal bone, which minimizes the gap between the implant and bone. The borders of the implant should be tapered sufficiently until no longer palpable or visible. Only 28 patients (5.4%) underwent a re-operation due to an undesirable postoperative appearance. The injection-molding technique using MMA is a simple, safe, and ideal method for the augmentation of the forehead.

Colorectal perforations are a serious condition associated with a high mortality. The aim of this study was to describe the clinical characteristics and identify predictors for the surgical mortality in adult patients with colorectal perforation, thereby achieving better outcomes. A retrospective study of adult patients diagnosed with colorectal perforation operated was performed. The clinical variables that might influence the surgical mortality were first analyzed, and the significant variables were then analyzed using a logistic regression model. A total of 423 patients were identified, and the surgical mortality rate was 36.9 %. The most common etiology was diverticulitis (38.2 %). The highest etiology-specific mortality was for colorectal cancer (61.5 %) and ischemic proctocolitis (59.8 %). In a logistic analysis, the significant predictors for the surgical mortality were ≥3 comorbidities (p = 0.034), preoperation American Society of Anesthesiologists score ≥4 (p = 0.025), preoperative sepsis or septic shock (p < 0.001), colorectal cancer or ischemic proctocolitis (p = 0.035), reoperation (p = 0.041), and Hinchey classification grade IV (p = 0.024). We demonstrated that ≥3 comorbidities, a preoperation American Society of Anesthesiologists score ≥4, preoperative sepsis or septic shock, colorectal cancer or ischemic proctocolitis, reoperation, and Hinchey classification grade IV are predictors for the surgical mortality in the adult cases of colorectal perforation. These predictors should be taken into consideration to prevent surgical mortality and to reduce potentially unnecessary medical expenses.

Checkrein ligament release for treatment of proximal interphalangeal joint Dupuytren contractures does not address the shortened arteries or deficient skin. The Digit Widget uses soft-tissue distraction to overcome these issues. This study compares checkrein ligament release after fasciectomy versus preliminary soft-tissue distraction, followed by operative release, for treatment of proximal interphalangeal joint Dupuytren contractures. The authors compared operative and postoperative characteristics of patients treated with either fasciectomy plus checkrein ligament release or Digit Widget distraction between 2001 and 2008. Seventeen patients (20 digits) underwent ligament release (mean contracture, 55.9 degrees); six of these 20 were reoperations. Thirteen patients (17 digits) underwent distraction (mean contracture, 67.6 degrees); 10 of 17 were reoperations. The 20 digits treated with fasciectomy plus ligament release had an average extension improvement of 31.4 degrees (range, -4 to 70 degrees). Digits treated with distraction had an average extension improvement of 53.4 degrees (range, 30 to 75 degrees) (p<0.001 versus ligament release). Three digits treated with distraction improved to full proximal interphalangeal extension. Initial contractures of 60 degrees or less treated by ligament release (n=12) or distraction (n=7) improved by means of 28.8 degrees and 47.7 degrees, respectively (p=0.048). Contractures greater than 60 degrees treated by ligament release (n=8) or distraction (n=10) improved by means of 35.3 degrees and 57.3 degrees, respectively (p=0.02). Soft-tissue distraction followed by operative release showed greater correction than Dupuytren fasciectomy plus checkrein ligament release. Therapeutic, III.

Despite good clinical outcome proposals, there has been relatively little published regarding the use of non-metallic implant for patellar fracture fixation. The purpose of the study was to perform a systematic literature review to summarize and evaluate the clinical studies that described techniques for treating patella fractures using non-metallic implants. A comprehensive literature search was systematically performed to evaluate all studies included in the literature until November 2015. The following search terms were used: patellar fracture, patella suture, patella absorbable, patella screw, patella cerclage. Two investigators independently reviewed all abstracts and the selection of these abstracts was then performed based on inclusion and/or exclusion criteria. A total of 9 studies involving 123 patients were included. Patients had a mean age of 33.7 years and were followed up for a mean of 18.9 months. The most common method for fracture fixations included the use of suture material. Good clinical outcomes were reported among all studies. Thirteen patients (10.5%) presented complications, while 4 patients (3.2%) required additional surgery for implant removal. There is a paucity of literature focused on the use of non-metallic implant for patellar fracture fixation. However, this systematic review showed that non-metallic implants are able to deliver good clinical outcomes reducing the rate of surgical complications and re-operation. These results may assist surgeons in choosing to use alternative material such as sutures to incorporate into their routine practice or to consider it, in order to reduce the rate of re-operation.

Objective Re-operative cardiac surgery is complicated in part because of extensive adhesions encountered during the second operation. The purpose of this study was to examine the effects of alcohol with and without resveratrol (red wine vs. vodka), on post-operative pericardial adhesion formation in a porcine model of hypercholesterolemia and chronic myocardial ischemia. Methods Male Yorkshire swine were fed a high-cholesterol diet to simulate conditions of coronary artery disease followed by surgical placement of an ameroid constrictor to induce chronic ischemia. Post-operatively, control pigs continued their high-cholesterol diet alone, while the two experimental groups had diets supplemented with either red wine or vodka. Seven weeks after ameroid placement, all animals underwent re-operative sternotomy. Results Compared to controls, pericardial adhesion grade was markedly reduced in the vodka group while there was no difference in the wine group. Intramyocardial fibrosis was significantly reduced in the vodka group compared to controls. There was no difference in expression of proteins involved in focal adhesion formation between any groups (FAK, Int α5, Int β1, Paxillin, Vinculin, PYK2, PKCε, p-PKCε). The wine group exhibited elevated CRP levels vs. control and vodka group. Conclusions Post-operative vodka consumption markedly reduced the formation of pericardial adhesions and intramyocardial fibrosis while red wine had no effect. Analysis of protein expression did not reveal any obvious explanation for this phenomenon, suggesting a post-translational effect of alcohol on fibrous tissue deposition. The difference in adhesion formation in the vodka vs. wine groups may be due to increased inflammation in the wine group. PMID:22244558

To assess the association between mortality in surgery of congenital heart disease in adults, and factors related to patients and operations. Descriptive study of operations performed by specialized surgeons in congenital heart surgery (238), adult acquired surgery (117), and specialty residents (108). The association of mortality with surgical risk and complexity, specialization of surgeon, cardiopulmonary by-pass and aortic cross clamping was assessed fitting logistic regression models. A total of 463 operations were included (442 with cardiopulmonary by-pass) in the study performed between 1991 and 2012. Median age at surgery: 34; 52.8% were women. First surgery: 295, reoperation: 168. Median score of Aristotle was 6.8, with significantly higher complexity since 2001, after restructuring the Unit. Overall hospital mortality was 3.9%. Mortality was significantly associated to number of previous surgeries (OR: 5.02; 95%CI: 1.44-17.52), operations by acquired heart disease surgeons (OR: 3.53; 95%CI: 1.14-10.98), higher Aristotle (OR: 1,64; 95%CI: 1.18-2.29), and high cardiopulmonary by-pass time (OR: 1.13; 95%CI: 1.07-1.19). Surgery of congenital heart disease in adults has been performed with low mortality. High complexity interventions, prolonged cardiopulmonary by-pass times and multiple reoperations were associated to higher mortality. Participation of cardiac surgeons specialized in congenital heart disease is associated with better outcomes. Copyright © 2013 Instituto Nacional de Cardiología Ignacio Chávez.

Several scores have been developed to define the inflammatory status of oncological patients. We suspect they share iterative information. Our hypothesis is that we may summarise their information into one or two new variables which will be independent. This will help us to predict, more accurately, which patients are at an increased risk of suffering postoperative complications after curative surgery for CRC. Observational prospective study with those patients undergoing curative surgery for CRC between September 2015 and February 2017. We analysed the influence of inflammatory scores (PNI, GPS, NLR, PLR) on postoperative morbidity (overall and severe complications, anastomotic leakage and reoperation). Finally, 168 patients were analysed. We checked these four original scores are interrelated among them. Using a complex and innovative statistical method, we created two new independent variables (resultant A and resultant B) which resume the information coming from them. One of these two new variables (resultant A) was statistically associated to overall complications (OR, 2.239; 95% CI, 1.541-3.253; p = 0.0001), severe complications (OR, 1.773; 95% CI, 1.129-2.785; p = 0.013), anastomotic leakage (OR, 3.208; 95% CI, 1.416-7.268; p = 0.005) and reoperation (OR, 2.349; 95% CI, 1.281-4.305; p = 0.006). We evinced the four original scores we used share redundant information. We created two new independent new variables which resume their information. In our sample of patients, one of these variables turned out to be a great predictive factor for the four complications we analysed.

What clinical characteristics and radiographic parameters are associated with patellofemoral instability after kinematically aligned total knee arthroplasty?

Thirteen patients presented with patellofemoral instability out of 3212 knees treated with kinematically aligned total knee arthroplasty (KA TKA) during a nine year period. We determined the clinical characteristics and post-operative radiographic parameters associated with patellofemoral instability, and whether re-operation and patient reported outcome measures are different between patients with and without patellofemoral instability. Patients with patellofemoral instability were matched 1:3 to a control cohort based on date of surgery (±3 months), age (±10 years), sex, pre-operative knee deformity (varus or valgus), and implant brand. We analyzed clinical characteristics and seven post-operative radiographic parameters. Patellofemoral instability presented atraumatically (12 of 13) at 5 ± 4.7 months for a 0.4 % incidence at a mean follow-up of 43 ± 36 months. No pre-operative clinical characteristics were associated with instability. Patients with patellofemoral instability had greater flexion of the femoral component (11° versus 5°; p = 0.0012), a trend toward greater external rotation of the tibial component (2° versus 0°; p = 0.2704), more reoperations (9 versus 0; p = 0.0026) and a lower Oxford Knee Score (36 versus 42; p = 0.0045) than controls. Patellofemoral instability after kinematically aligned TKA is infrequent, presents atraumatically, and is associated with greater flexion of the femoral component than the control group. Minimizing flexion of the femoral component might reduce the risk of patellofemoral instability by promoting early engagement of the patella in the trochlear during knee flexion.

Re-exploration of the lumbar spine following simple discectomy: a review of 23 cases.

Shiraishi, T; Crock, H V

1995-01-01

A retrospective study of 23 patients is presented, all of whom complained of recurrent symptoms of back and leg pain following simple discectomy. Five patients (22%) had been refused further surgery by the original surgeon on the grounds that they were psychologically disturbed. On examining the clinical records, 18 patients were reported to have had frank disc prolapses found at operation. In 5 cases, disc tissues were removed even though disc prolapses had not been demonstrated. Among the 18 patients in whom disc prolapses had been removed at their first operations, we found recurrent prolapses at reoperation in only 2 of them (11%). We treated 19 of these patients by nerve root canal and foraminal decompressions and 4 by anterior lumbar interbody fusion operations. The mean follow-up period was 34 months. Satisfactory relief of symptoms was achieved in 21 cases. In the published literature, even after the advent of CT and MRI, the incidence of recurrent disc prolapse at reoperation varies markedly from author to author. The reasons for these differences are discussed. They appear to relate to three factors: 1. failure to differentiate acute disc prolapse from annular bulging which develops and is inevitably associated with disc space narrowing; 2. difficulty in distinguishing between MRI findings of scar tissue enhancement and local perineural oedema due to persisting foraminal and nerve root canal stenosis; 3. failure to identify the existence of foraminal stenosis, which is sometimes demonstrated only in oblique plain X-rays showing facet hypertrophy and subluxations of zygapophyseal joints.(ABSTRACT TRUNCATED AT 250 WORDS)

AIM: To analyze the difference in disease course and need for surgery in patients with Crohn’s disease (CD). METHODS: Data of 506 patients with incident CD were analyzed (age at diagnosis: 31.5 ± 13.8 years). Both hospital and outpatient records were collected prospectively with a complete clinical follow-up and comprehensively reviewed in the population-based Veszprem province database, which includes incident CD patients diagnosed between January 1, 1977 and December 31, 2008. Follow-up data were collected until December 31, 2009. All patients included had at least 1 year of follow-up available. Patients with indeterminate colitis at diagnosis were excluded from the analysis. RESULTS: Overall, 73 patients (14.4%) required resective surgery within 1 year of diagnosis. Steroid exposure and need for biological therapy were lower in patients with early limited surgery (P < 0.001 and P = 0.09). In addition, surgery rates during follow-up in patients with and without early surgery differed significantly after matching on propensity scores (P < 0.001, HR = 0.23). The need for reoperation was also lower in patients with early limited resective surgery (P = 0.038, HR = 0.42) in a Kaplan-Meier and multivariate Cox regression (P = 0.04) analysis. However, this advantage was not observed after matching on propensity scores (PLogrank = 0.656, PBreslow = 0.498). CONCLUSION: Long-term surgery rates and overall exposure to steroids and biological agents were lower in patients with early limited resective surgery, but reoperation rates did not differ.

In the pediatric population, glutaraldehyde-preserved bovine pericardium conduit containing a stentless porcine valve has been proposed as an alternative to homografts for right ventricular outflow tract reconstruction. Between June 1996 and March 2000, a total of 55 patients, 20 with truncus arteriosus, 21 with pulmonary atresia with ventricular septal defect, and 14 with miscellaneous defects, received this conduit. Median age at implantation was 3.4 months (range, 3 days to 19 years), and 27 patients (50%) were less than 3 months old. Clinical outcome, echocardiographic data, and pathologic analysis were recorded. End points for conduit failure were conduit replacement or dilation. A mean follow-up of 27 months (range, 2 to 46 months) was available for 47 survivors. Procedure for conduit obstruction was required in 13 patients. The most common procedure was operation, and all but 3 patients had an unsuccessful balloon angioplasty before reoperation. Actuarial freedom from conduit dilation or reoperation was 93.6% (95% confidence limits, 82% to 99%), 81.9% (95% confidence limits, 64% to 91%), 77.8% (95% confidence limits, 39% to 78%), and 64.3% (95% confidence limits, 26% to 73%) at 1, 2, 3, and 4 postoperative years, respectively. Univariate analysis identified small conduit size as a risk factor for conduit obstruction. Although this new conduit was not free from progressive obstruction, our clinical results (easy to work and good valvular function) and the availability in small sizes encouraged us to use it as an alternative to small-size homografts when those were not available.

Background The Ross/Ross-Konno procedure is considered a good option for irreparable aortic valve disease in pediatric patients because of its hemodynamic performance and potential for growth of the pulmonary autograft. This study is a review of the long-term results of our 20-year experience with the Ross and Ross-Konno operations in a single institution. Methods Between June 1995 and January 2016, 16 consecutive patients (mean age, 6.0±5.9 years; range, 16 days to 17.4 years) underwent either a Ross operation (n=9) or a Ross-Konno operation (n=7). The study included 12 males and 4 females, with a median follow-up period of 47 months (range, 6 to 256 months). Results There were no cases of in-hospital or late mortality. Six reoperations were performed in 5 patients. Four patients underwent right ventricular-pulmonary artery (RV-PA) conduit replacement. Two patients underwent concomitant replacement of the pulmonary autograft and RV-PA conduit 10 years and 8 years after the Ross operation, respectively. The rate of freedom from adverse outcomes of the pulmonary autograft was 88% and 70% at 5 and 10 years, respectively. The rate of freedom from valve-related reoperations was 79% and 63% at 5 and 10 years, respectively. Conclusion Pulmonary autografts demonstrated good durability with low mortality. The Ross/Ross-Konno procedure is a good option that can be performed safely in pediatric patients with aortic valve disease, even in a small-volume center. PMID:28795027

Minimal access mitral valve surgery (MVS) has already proved to be feasible and effective with low perioperative mortality and excellent long-term outcomes. However, experience in more complex valve diseases such as infective endocarditis (IE) still remains limited. The aim of this retrospective study was to evaluate early and long-term results of minimal access MVS for IE. Data were entered into a dedicated database. Analysis was performed retrospectively for the 8-year period between January 2007 and April 2015. During the study period, 35 consecutive patients underwent minimal access MVS for IE at our department. Twenty-four had diagnosis of native MV endocarditis (68.6%) and 11 of mitral prosthesis endocarditis (31.4%).Thirty patients underwent early MVS (85.7%), and 5 patients were operated after the completion of antibiotic treatment (14.3%). Seven patients underwent MV repair (20%), 17 patients underwent MV replacement (48.6%), and 11 patients underwent mitral prosthesis replacement (31.4%). Thirty-day mortality was 11.4% (4 patients). No neurological or vascular complications were reported. One patient underwent reoperation for prosthesis IE relapse after 37 days. Overall actuarial survival rate at 1 and 5 years was 83%; freedom from MV reoperation and/or recurrence of IE at 1 and 5 years was 97%. Minimally invasive MVS for IE is feasible and associated with good early and long-term results. Preoperative accurate patient selection and transoesophageal echocardiography evaluation is mandatory for surgical planning. © The Author 2017.

Craniofacial chondroid tumors (CFCTs) constitute less than 1% of all intracranial mass lesions. No protocol for evaluation and management of CFCTs is developed at the moment. We analyzed 51 patients with CFCTs operated on in Burdenko Neurosurgical Institute from 1980 until 2012, which included chondroma (15), chondroblastoma (3), chondromyxoid fibroma (11), and chondrosarcoma (22). Age varied from 2 to 76 years (mean, 40 y); the series included 23 women and 28 men. All tumors were divided into 4 groups: midline unilateral (8),midline bilateral (21), anterolateral (19), and lateral (3). This division was based on differences in surgical approaches (P = 0.009). All patients underwent surgical treatment. Complete removal was achieved in 20; subtotal, in 21; and partial, in 10. Two patients died, and early complications were observed in 10 cases. Early outcomes correlated with the benign nature of the tumors (P = 0.002). Follow-up data were available in 22 patients. Fifteen of 51 patients were reoperated on because of recurrence (a total of 43 reoperations were performed). The mean recurrence-free period was 45 months. In 3 patients, the tumor metastasized, and malignant transformation was observed in 3 cases. Sixteen patients received postoperative radiation therapy. Delayed sequelae occurred in 5 observations, and 5 patients died during long-term follow-up. Three-year survival in benign and malignant tumors was 87.5% and 55.6%, respectively, and 5-year survival was 83.3% and 40.0%, respectively. Surgical resection is the mainstay in treatment of both benign and malignant craniofacial tumors, and adjuvant radiation therapy is mandatory in malignant lesions; however, it should be avoided in benign lesions.

Background The forehead, which occupies about one third of the face, is one of the major determinants of a feminine or masculine look. Various methods have been used for the augmentation of the forehead using autologous fat grafts or alloplastic materials. Methylmethacrylate (MMA) is the most appropriate material for augmentation of the forehead, and we have used an injection-molding technique with MMA to achieve satisfactory results. Methods Under local anesthesia with intravenous (IV) sedation, an incision was made on the scalp and a meticulous and delicate subperiosteal dissection was then performed. MMA monomers and polymers were mixed, the dough was injected into the space created, and manual molding was performed along with direct inspection. This surgery was indicated for patients who wanted to correct an unattractive appearance by forehead augmentation. Every patient in this study visited our clinics 3 months after surgery to evaluate the results. We judged the postoperative results in terms of re-operation rates caused by the dissatisfaction of the patients and complications. Results During a 13-year period, 516 patients underwent forehead augmentation with MMA. With the injection-molding technique, the inner surface of the MMA implant is positioned close to the underlying frontal bone, which minimizes the gap between the implant and bone. The borders of the implant should be tapered sufficiently until no longer palpable or visible. Only 28 patients (5.4%) underwent a re-operation due to an undesirable postoperative appearance. Conclusions The injection-molding technique using MMA is a simple, safe, and ideal method for the augmentation of the forehead. PMID:24086816

We report a rare case of anterolateral meningioma of the foramen magnum (FMM) and high cervical spine presenting both intradural and extradural growth in a 7.5-year-old boy. We also performed a review of the relevant peer-reviewed literature. The patient presented with progressive tetraparesis and gait instability. Neuroimaging revealed an anterolateral tumor of the foramen magnum, C1 and C2 cervical spine level. The patient was treated in two stages: During the first operation, the extradural part was resected while the intradural part was removed in a second operation. Following the second operation, the patient showed almost complete neurological recovery as a result of cervical spinal cord and brainstem decompression but was complicated with cerebrospinal fluid leakage and infection by Acinetobacter. He sustained two further operations for dural sealing and external ventricular drainage and was treated with intraventricular administration of antibiotics. Histopathology of the tumor confirmed a meningotheliomatous meningioma. At the 6-month post-op follow-up examination, the patient exhibited complete neurological recovery and no radiological tumor recurrence. To the authors' best knowledge, we report the third case of sporadic pediatric meningioma of the foramen magnum and high cervical compartments with an extradural growth. Accurate pre-operative estimation of possible extradural growth is crucial towards surgical planning and sufficient treatment. Treatment of choice is total resection in a single operating session to avoid re-operations and increased risk of complications. If not possible, a re-operation should always attempt to secure the desired result.

The management of symptomatic pancreatic fistula after pancreaticoduodenectomy is complex and associated with increased morbidity and mortality. We here report continuous irrigation and drainage of the pancreatic remnant to be a feasible and safe alternative to total pancreatectomy. Between 2005 and 2011, patients were analyzed, in which pancreaticojejunal anastomosis was disconnected because of grade C fistula, and catheters for continuous irrigation and drainage were placed close to the pancreatic remnant. Clinical data were monitored and quality of life was evaluated. A total of 13 of 202 patients undergoing pancreaticoduodenectomy required reoperation due to symptomatic pancreatic fistula. Ninety-day mortality of these patients was 15.3%. Median length of stay on the intensive care unit and total length of stay was 18 d (range 3-45) and 46 d (range 33-96), respectively. Patients with early reoperation (<10 d) had significantly decreased length of stay on the intensive care unit and operation time (P < 0.05). Global health status after a median time of 22 mo (range 6-66) was nearly identical, when compared with that of a healthy control group. Mean follow-up was 44.4 mo (±27.2). Four patients (36.6 %) died during the follow-up period; two patients from tumor recurrence, one patient from pneumonia, and one patient for unknown reasons. Treatment of pancreatic fistula by continuous irrigation and drainage of the preserved pancreatic remnant is a simple and feasible alternative to total pancreatectomy. This technique maintains a sufficient endocrine function and is associated with low mortality and reasonable quality of life. Copyright © 2015 Elsevier Inc. All rights reserved.

Since Allen O. Whipple published his seminal paper in 1935, the procedure that bears his name has been performed widely throughout the world and is now a common operation in major medical centers. The goal of this study was to investigate the evolution of pancreatoduodenectomy at the Massachusetts General Hospital (MGH). We sought to identify all pancreatoduodenectomies performed at the MGH since 1935. Cases were obtained from a computerized database, hospital medical records, and the MGH historical archive. Demographics, diagnosis, intraoperative variables and short-term surgical outcomes were recorded. The first pancreatoduodenectomy at the MGH was carried out in 1941; since then, 2,050 Whipple procedures have been performed. Pancreatic ductal adenocarcinoma was the most frequent indication (36%). Pylorus preservation has been the most important variation in technique, accounting for 45% of Whipple procedures in the 1980s; observation of frequent delayed gastric emptying after this procedure led to decline in its use. Pancreatic fistula was the most frequent complication (13%). Operative blood replacement and reoperation rates have decreased markedly over time; the most frequent indication for reoperation was intra-abdominal bleeding. Mortality has decreased from 45% to 0.8%, with sepsis and hypovolemic shock being the most frequent causes of death. Mean duration of hospital stay has decreased from >30 to 9.5 days, along with an increasing readmission rate (currently 19%). The Whipple procedure in the 21st century is a well-established operation. Improvements in operative technique and perioperative care have contributed in making it a safe operation that continues evolving. Copyright © 2012 Mosby, Inc. All rights reserved.

This retrospective study assessed the functional results of open Latarjet operation for recurrence of instability after arthroscopic Bankart repair in a consecutive series of patients. Fifty two patients (mean age 28.4 [range 17-62] years, 45 men) were operated on using open Latarjet operation after one (n=46) or two (n=6) failed arthroscopic Bankart repairs. The indication for revision surgery was recurrent dislocation or subluxation. Fifty patients had a Hill-Sachs lesion and 32 patients had glenoid bone lesions on plain radiographs. No attempt was made to grade the severity of bony pathology. Functional outcome and stability of 49 shoulders were assessed after an average follow-up of 38 (range 24-85) months using Western Ontario Shoulder Instability (WOSI) score, Oxford shoulder instability score, and subjective shoulder value (SSV). Forty-two patients had a stable shoulder at follow-up. Seven of 49 (14%) had symptoms of instability; one patient had recurrent dislocation, and six patients had subluxations. Mean WOSI, Oxford, and SSV scores were 83.9, 19.9, and 84.9, respectively. All scores were significantly better in patients who had a stable shoulder compared with those who had an unstable shoulder (WOSI 86.8 vs. 64.3; Oxford 18.2 vs. 30.8; and SSV 88.3 vs. 61.7; P<0.01). One patient needed a reoperation. There were no intraoperative or postoperative complications. Open Latarjet operation is a good option for failed arthroscopic Bankart repair. The instability recurrence rate is acceptable and the reoperation rate was low. Level IV, retrospective case series. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Retrospective database review. Posterior/posterolateral lumbar fusion (PLF) is an effective treatment for a variety of spinal disorders; however, variations in surgical technique have different complication profiles. The aim of our study was to quantify the frequency of various complications in patients undergoing PLF with and without human recombinant bone morphogenetic protein 2 (rhBMP2). We queried the orthopedic subset of the Medicare database (PearlDiver) between 2005 and 2011 for patients undergoing PLF procedures with and without rhBMP2. Complication and reoperation rates were analyzed within 1 year of the index procedure. Complications assessed include: acute renal failure, deep vein thrombosis, dural tear, hematoma, heterotopic ossification, incision and drainage, cardiac complications, nervous system complications, osteolysis, pneumonia, pseudarthrosis, pulmonary embolism, radiculopathy, respiratory complications, sepsis, urinary retention, urinary tract infection, mechanical, and wound complications. Chi-square analysis was used to calculate the complication differences between the groups. Our data revealed higher overall complication rates in patients undergoing PLF with rhBMP2 versus no_rhBMP2 (76.9% vs 68.8%, P < .05). Stratified by gender, rhBMP2 males had higher rates of mechanical complications, pseudarthrosis, and reoperations compared with no_rhBMP2 males ( P < .05), whereas rhBMP2 females had higher rates of pseudarthrosis, urinary tract infection, and urinary retention compared with no_rhBMP2 females ( P < .05). Our data revealed higher overall complication rates in PLF patients given rhBMP2 compared with no_rhBMP2. Furthermore, our data suggests that rhBMP2-associated complications may be gender specific.

Robotic-assisted coronary artery bypass grafting (r-CABG) requires the placement of ports bluntly through the chest wall. When removed, these ports create bleeding sites that can be difficult to detect and treat. This study evaluated whether a topical hemostatic agent placed locally within these sites helps to reduce bleeding and blood product requirements. We retrospectively analyzed outcomes for r-CABG cases where 5 mL of a flowable hemostatic agent was injected locally within all port sites (hemostat group, n = 62) compared with patients whose port sites were untreated (controls, n = 131). Outcomes included chest tube output, red blood cell (RBC) transfusions, length of hospital stay, and the risk of reoperation for bleeding. Analyses were adjusted for risk factors known to influence bleeding and Society of Thoracic Surgeons (STS) risk score as a weighted composite of variables, which controls for patient and clinical variables. The 2 study groups had similar baseline characteristics and underwent the same r-CABG procedure. The hemostat group had significant reductions in RBC transfusion (24.2% versus 40.8% receiving blood; P = .026; 0.44 versus 1.39 U transfused postoperatively, P = .024). After adjustment for bleeding risks (using STS risk score), differences in transfusions remained significant. Reoperation rates for bleeding, length of stay, chest tube drainage, and intraoperative transfusions were not significantly different in the 2 groups. There was significantly reduced postoperative bleeding and less exposure to blood products in the hemostat group. These findings suggest that undetected bleeding from sites used for port access serves as an underappreciated source of morbidity after r-CABG.

The present study performed a meta-analysis to evaluate the efficacy and safety of interspinous process distraction device (IPD) compared with open decompression surgery (ODS) in treating lumbar spinal stenosis. Literatures were searched in the databases including Cochrane Library, Pubmed, OvidSP, Sciencedirect, Web of Science, and Springerlin. Published reviews were checked to track missed original research papers. The quality and bias of publications with randomized controlled trial were evaluated using the tool for assessing risk of bias in the Cochrane handbook. The quality and bias of publications with cohort trial were evaluated using the Newcastle-Ottawa Scale. The grades of literatures were evaluated with the guidelines of Grading of Recommendations Assessment Development and Evaluation (GRADE). Totally, 21 publications matched the inclusion criteria, including 20 different clinical trials and 54,138 patients. The results indicated that there was no significant difference in improvement rate, Oswestry disability index questionnaire (ODI) score, and visual analog scale (VAS) score of back pain or leg pain between IPD group and ODS group. The postoperation complication rate, perioperation blood loss, hospitalization time, and operation time were lower/shorter in IPD group than ODS group. However, the reoperation rate in IPD group was higher than ODS group. The results indicated that IPD has better effects and less complication than ODS. However, because of the higher reoperation rate in IPD than ODS, we failed to conclude that IPD could replace ODS as golden standard but may be a viable alternative in treating lumbar spinal stenosis.
