OBJECTIVE Thoracolumbar fractures account for 90% of spinal fractures, with the burst subtype corresponding to 20% of this total. Controversy regarding the best treatment for this condition remains. The traditional surgical approach, when indicated, involves spinal fixation and arthrodesis. Newer studies have brought the need for fusion associated with internal fixation into question. Not performing arthrodesis could reduce surgical time and intraoperative bleeding without affecting clinical and radiological outcomes. With this study, the authors aimed to assess the effect of fusion, adjuvant to internal fixation, on surgically treated thoracolumbar burst fractures. METHODS A search of the Medline and Cochrane Central Register of Controlled Trials databases was performed to identify randomized trials that compared the use and nonuse of arthrodesis in association with internal fixation for the treatment of thoracolumbar burst fractures. The search encompassed all data in these databases up to February 28, 2016. RESULTS Five randomized/quasi-randomized trials, which involved a total of 220 patients and an average follow-up time of 69.1 months, were included in this review. No significant difference between groups in the final scores of the visual analog pain scale or Low Back Outcome Scale was detected. Surgical time and blood loss were significantly lower in the group of patients who did not undergo fusion (p < 0.05). Among the evaluated radiological outcomes, greater mobility in the affected segment was found in the group of those who did not undergo fusion. No significant difference between groups in the degree of kyphosis correction, loss of kyphosis correction, or final angle of kyphosis was observed. CONCLUSIONS The data reviewed in this study suggest that the use of arthrodesis did not improve clinical outcomes, but it was associated with increased surgical time and higher intraoperative bleeding and did not promote significant improvement in radiological parameters.

Carcinomas of the mandible may require resection of a segment of bone (continuity defect), partial removal of bone (discontinuity defect), tongue, and floor of the mouth and muscle attachments. Patients undergoing such treatment suffer from facial disfigurement, loss of muscle function, loss of neuromuscular coordination resulting in inability to masticate and swallow acceptably. Surgical reconstruction may not always be possible because of high reoccurrence rate, inability of the patient to cope with another surgery etc. The treatment of choice in non surgical cases is prosthetic rehabilitation using guiding flange prosthesis. This article describes the management of a patient who had undergone hemimandibulectomy and was not willing for a surgical reconstruction. Interim maxillary ramp prosthesis was given to the patient 15 days postoperatively followed by definitive guiding flange prosthesis for two years after which the patient was able to occlude in centric occlusal position without any aid.

Brain shift describes the deformation that the brain undergoes from mechanical and physiological effects typically during a neurosurgical or neurointerventional procedure. With respect to image guidance techniques, brain shift has been shown to compromise the fidelity of these approaches. In recent work, a computational pipeline has been developed to predict "brain shift" based on preoperatively determined surgical variables (such as head orientation), and subsequently correct preoperative images to more closely match the intraoperative state of the brain. However, a clinical workflow difficulty in the execution of this pipeline has been acquiring the surgical variables by the neurosurgeon prior to surgery. In order to simplify and expedite this process, an Android, Java-based application designed for tablets was developed to provide the neurosurgeon with the ability to orient 3D computer graphic models of the patient's head, determine expected location and size of the craniotomy, and provide the trajectory into the tumor. These variables are exported for use as inputs for the biomechanical models of the preoperative computing phase for the brain shift correction pipeline. The accuracy of the application's exported data was determined by comparing it to data acquired from the physical execution of the surgeon's plan on a phantom head. Results indicated good overlap of craniotomy predictions, craniotomy centroid locations, and estimates of patient's head orientation with respect to gravity. However, improvements in the app interface and mock surgical setup are needed to minimize error.

To study the rate of postoperative hypocalcemia following completion thyroidectomy (CT), in comparison with the hypocalcemia rate following total thyroidectomy (TT). A retrospective study, performed at the McGill University Thyroid Cancer Center, Montreal, Quebec, Canada, from 2007 to 2012. Medical records of adult patients undergoing CT and TT operated by a single surgeon were reviewed. Data were extracted for demographics, postoperative calcium levels, surgical logs, and final surgical pathology. Hypocalcemia was defined as corrected serum calcium level ≤ 1.90 mmol/L, with concurrent serum parathyroid hormone <8 ng/L, and/or any signs or symptoms of hypocalcemia. There were 68 CTs and 146 TTs. Transient hypocalcemia occurred in 1 of 68 (1.5%) and 18 of 146 (12.5%) patients in the CT and TT groups, respectively. The rate of hypocalcemia was significantly lower in the CT compared with the TT group (P = .02). In both groups, there were no cases of permanent hypocalcemia. The risk of transient of hypocalcemia in patients undergoing CT is significantly lower than the rate of hypocalcemia in patients undergoing TT. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

Efficacy of incisional gastropexy for prevention of GDV in dogs.

Incisional gastropexy (IG) is routinely performed as either a prophylactic procedure to prevent occurrence of gastric dilatation-volvulus (GDV) or at the time of surgical correction of GDV to prevent recurrence. Despite its common use, the long-term efficacy of the IG procedure has not been reported. The hypothesis of this study was that IG performed either during surgical treatment of GDV or as a prophylactic measure would effectively prevent GDV. Medical records of 61 dogs undergoing IG following either gastric derotation for treatment of GDV or as a prophylactic procedure were evaluated retrospectively. Median follow-up time for all dogs was 717 days (range, 49-2,511 days). Of the 61 dogs, 27 had prophylactic IG performed. The remaining 34 dogs presented for GDV and had an IG performed during surgical treatment of GDV. No dog experienced GDV after IG. Recurrence of gastric dilatation (GD) alone was noted in 3 of 34 patients (8.8%) undergoing IG during surgery for GDV and in 3 of 27 patients (11.1%) treated prophylactically with IG. This study confirmed the efficacy of IG for the long-term prevention of GDV in dogs.

Gynecomastia is defined as the benign enlargement of the male breast. Multiple surgical options have been used to improve outcomes. The aim of this study was to analyze the surgical approaches to the treatment of gynecomastia and their outcomes over a 10-year period. All patients undergoing surgical correction of gynecomastia in our department between 2000 and 2010 were included for retrospective evaluation. The data were analyzed for etiology, stage of gynecomastia, surgical technique, complications, risk factors, and revision rate. The surgical result was evaluated with self-assessment questionnaires. A total of 41 patients with 75 operations were included. Techniques included subcutaneous mastectomy alone or with additional ultrasound-assisted liposuction (UAL) and isolated UAL. The surgical revision rate for all patients was 4.8%. The skin-sparing procedure gave good surgical results in grade IIb and grade III gynecomastia with low revision and complication rates. The self-assessment report revealed a good level of overall satisfaction and improvement in self-confidence (average scores 9.4 and 9.2, respectively, on a 10-point scale). The treatment of gynecomastia requires an individualized approach. Subcutaneous mastectomy combined with UAL could be used as the first choice for surgical treatment of grade II and III gynecomastia.

Little is known about the effect of androgen receptor (AR) gene CAG repeat polymorphism in conditioning body composition changes after testosterone replacement therapy (TRT). In this study, we aimed to clarify this aspect by focussing our attention on male post-surgical hypogonadotropic hypogonadism, a condition often associated with partial or total hypopituitarism. Fourteen men affected by post-surgical hypogonadotropic hypogonadism and undergoing several replacement hormone therapies were evaluated before and after TRT. Dual-energy X-ray absorptiometry (DEXA)-derived body composition measurements, pituitary-dependent hormones and AR gene CAG repeat polymorphism were considered. While testosterone and insulin-like growth factor-1 (IGF-1) levels increased after TRT, cortisol concentration decreased. No anthropometric or body composition parameters varied significantly, except for abdominal fat decrease. The number of CAG triplets was positively and significantly correlated with this abdominal fat decrease, while the opposite occurred between the latter and Δ-testosterone. No correlation of IGF-1 or cortisol variation (Δ-) with Δ-abdominal fat was found. At multiple linear regression, after correction for Δ-testosterone, the positive association between CAG triplet number and abdominal fat change was confirmed. In male post-surgical hypogonadotropic hypogonadism, shorter length of AR CAG repeat tract is independently associated with a more marked decrease of abdominal fat after TRT.

To describe a novel surgical technique for the correction of recurrent obstructive urolithiasis in male goats. Clinical case series. Castrated male goats (n = 4). Medical records of male goats having undergone vesicopreputial anastomosis (VPA) as a treatment for obstructive urolithiasis were reviewed for history, signalment, clinical signs, and intraoperative and postoperative complications. Long-term follow-up (≥12 months) was obtained by telephone interview with owners or by clinical examination. All goats had undergone at least one surgical procedure (median, 2.5, range 2-4) to correct obstructive urolithiasis before undergoing VPA. Postoperative complications included premature removal of the tube from the bladder (1 goat), bacterial cystitis (2), and abscess formation (1). One goat suffered stricture of the anastomosis site 3 months following the original procedure and underwent a second VPA and 1 goat died 7 months after surgery due to severe, acute hydronephrosis and renal failure. Long-term survival ≥12 months was good with 3/4 goats (75%) or 3/5 VPA procedures (60%) having unobstructed urine flow at 12 months. Vesicopreputial anastomosis is a feasible surgical procedure for the correction of recurrent obstructive urolithiasis in male goats and one that can result in a favorable clinical outcome. Further investigation in a larger population of goats is warranted for the evaluation of the suitability of VPA in male goats with obstructive urolithiasis. © 2017 The American College of Veterinary Surgeons.

Antifibrinolytics such as tranexamic acid reduce operative blood loss and blood product transfusion requirements in patients undergoing surgical correction of scoliosis. The factors involved in the unrelenting coagulopathy seen in scoliosis surgery are not well understood. One potential contributor is activation of the fibrinolytic system during a surgical procedure, likely related to clot dissolution and consumption of fibrinogen. The addition of tranexamic acid during a surgical procedure may mitigate the coagulopathy by impeding the derangement in D-dimer and fibrinogen kinetics. We retrospectively studied consecutive patients who had undergone surgical correction of adult spinal deformity between January 2010 and July 2016 at our institution. Intraoperative hemostatic data, surgical time, estimated blood loss, and transfusion records were analyzed for patients before and after the addition of tranexamic acid to our protocol. Each patient who received tranexamic acid and met inclusion criteria was cohort-matched with a patient who underwent a surgical procedure without tranexamic acid administration. There were 17 patients in the tranexamic acid cohort, with a mean age of 60.7 years, and 17 patients in the control cohort, with a mean age of 60.9 years. Estimated blood loss (932 ± 539 mL compared with 1,800 ± 1,029 mL; p = 0.005) and packed red blood-cell transfusions (1.5 ± 1.6 units compared with 4.0 ± 2.1 units; p = 0.001) were significantly lower in the tranexamic acid cohort. In all single-stage surgical procedures that met inclusion criteria, the rise of D-dimer was attenuated from 8.3 ± 5.0 μg/mL in the control cohort to 3.3 ± 3.2 μg/mL for the tranexamic acid cohort (p < 0.001). The consumption of fibrinogen was 98.4 ± 42.6 mg/dL in the control cohort but was reduced in the tranexamic acid cohort to 60.6 ± 35.1 mg/dL (p = 0.004). In patients undergoing spinal surgery, intravenous administration of tranexamic acid is effective at reducing intraoperative blood loss. Monitoring of D-dimer and fibrinogen during spinal surgery suggests that tranexamic acid impedes the fibrinolytic pathway by decreasing consumption of fibrinogen and clot dissolution as evidenced by the reduced formation of D-dimer.

This study sought to assess the relative merit of surgical correction (SC) versus transcatheter reduction on long-term outcomes in patients with significant paravalvular leak (PVL) refractory to medical therapy. PVL is the most frequent dysfunction following prosthetic valve replacement. Although repeat surgery is the gold standard, transcatheter reduction (TR) of PVL has been associated with reduced mortality. From 1994 to 2014, 231 patients underwent SC (n = 151) or TR (n = 80) PVL correction. Propensity matching and Cox proportional hazards regression models were used to assess the effect of either intervention on long-term rates of all-cause death or hospitalization for heart failure. Survival after TR and SC were further compared with the survival in a matched general population and to matched patients undergoing their first surgical valve replacement. Over a median follow-up of 3.5 years, SC was associated with an important reduction in all-cause death or hospitalization for heart failure compared with TR (hazard ratio: 0.28; 95% confidence interval: 0.18 to 0.44; p < 0.001). There was a trend towards reduced all-cause death following SC versus TR (hazard ratio: 0.61; 95% confidence interval: 0.37 to 1.02; p = 0.06). Neither intervention normalized survival when compared with a general population or patients undergoing their first surgical valve replacement. In patients with significant prosthetic PVL, surgery is associated with better long-term outcomes compared with transcatheter intervention, but results in important perioperative mortality and morbidity. Future studies are needed in the face of increasing implementation of transcatheter PVL interventions across the world. Copyright © 2017 American College of Cardiology Foundation.

We sought to define the inferior sinus venosus defect anatomically and document successful surgical approaches. We identified all patients previously given a diagnosis of an inferior sinus venosus defect at the Hospital for Sick Children, Toronto, Canada, between 1982 and 2005 by interrogating the cardiology and cardiac surgery databases. We included those having interatrial communications in which 1 or more of the right pulmonary veins drained to the inferior caval vein but retained connection with the left atrium, the rims of the oval fossa, and the walls of the coronary sinus, both being intact. We identified 11 children who had an interatrial communication meeting the criteria for and undergoing surgical repair of an inferior sinus venosus defect. Median age was 1.2 years; 6 (55%) subjects were male, and none were cyanotic. Transthoracic echocardiographic analysis was performed preoperatively in all children, revealing right ventricular dilation in all. Surgical repair was accomplished with a pericardial patch. A complex baffle was needed in 3 children to maintain unobstructed inferior caval and pulmonary venous return. The echocardiographic diagnosis was complete in only 5 patients, but all diagnoses were correct since the year 2000. In all children the observations at surgical intervention showed that the defect was a venoatrial communication involving drainage of the right pulmonary veins to the inferior caval vein while retaining connection to the left atrium. Transthoracic echocardiographic analysis should remain the modality of choice for diagnosis of the inferior sinus venosus defect. We report excellent surgical results with a patch or baffle, correctly redirecting the anomalous venoatrial connections.

The surgical treatment of comorbid erectile dysfunction and Peyronie's disease has long included the implantation of an inflatable penile prosthesis as well as a number of adjuvant maneuvers to address residual curvature after prosthesis placement. To review the various surgical options for addressing curvature after prosthesis placement, with specific attention paid to an original article by Wilson et al. reporting on modeling over a penile prosthesis for the management of Peyronie's disease. A literature review was performed analyzing articles reporting the management of penile curvature in patients undergoing implantation of an inflatable penile prosthesis. Reported improvement in Peyronie's deformity as well as the complication rate associated with the various surgical techniques described. Modeling is a well-established treatment modality among patients with Peyronie's disease undergoing penile prosthesis implantation. A variety of other adjuvant maneuvers to address residual curvature when modeling alone is insufficient has been presented in the literature. Over 20 years of experience with modeling over a penile prosthesis have proven the efficacy and safety of this treatment option, providing the surgeon a simple initial step for the management of residual curvature after penile implantation which allows for the use of additional adjuvant maneuvers in those with significant deformities. © 2015 International Society for Sexual Medicine.

A computed tomographic study. To investigate the changed anatomic relationship between the superior mesenteric artery and the aorta in surgically treated ankylosing spondylitis (AS) patients with thoracolumbar kyphosis. Superior mesenteric artery syndrome in kyphosis patients after surgery has been reported. To date, the changed aortomesenteric angle and distance in AS patients undergoing surgical correction of kyphosis have not yet been addressed. Thirty-three AS patients with thoracolumbar kyphosis subjected to pedicle subtraction osteotomy were prospectively recruited. Radiographic measurements included global kyphosis (GK), thoracic kyphosis (TK), local kyphosis (LK), and lumbar lordosis. The aortomesenteric angle and distance were measured on both preoperative and postoperative computed tomography images. The height and weight of these patients were also recorded. The average height significantly increased from 159.7±5.1 cm before surgery to 167.2±5.3 cm after surgery (P<0.001), whereas the average weight changed from 59.3±6.8 kg to 59.5±6.9 kg (P>0.05). GK, TK, LK, and lumbar lordosis were corrected from 77.7, 40.2, 19.4, and 2.8 degrees before surgery to 37.1, 38.4, -21.9, and -32 degrees after surgery, respectively. All the changes of these parameters were found to be significantly different (P<0.001) except that of TK (P>0.05). With the correction of kyphosis, the aortomesenteric angle significantly decreased from 29.3 to 23.4 degrees (P<0.001), whereas the aortomesenteric distance significantly decreased from 25.7 to 20.4 mm (P<0.001). It is to be noted that the changes of GK, LK, and height were significantly correlated with the decrements of aortomesenteric angle and distance (P<0.05). The correlations of the surgical correction of kyphosis and the decreased aortomesenteric angle and distance in AS patients were quantitatively confirmed by our study. Spine surgeons should be aware of the potential risk for the development of superior mesenteric artery syndrome after kyphosis correction in AS patients.

Fibrin glue for local haemostasis in haemophilia surgery.

PubMed

Rodriguez-Merchan, E Carlos

2017-12-01

Local fibrin glue (FG) appears to be a useful local haemostatic agent for severe haemorrhage in people with haemophilia (PWH) undergoing surgical procedures. To evaluate the role of local FG in PWH. A review of the literature on the topic has been performed. Local FG is not always necessary to achieve haemostasis in all surgical procedures performed in PWH. However, it could be a good adjunct therapy, primarily when a surgical field will bleed more than expected (e.g. patients with inhibitors), and also for circumcisions, dental extractions, and surgical treatment of pseudotumours. Although correct surgical haemostasis can typically be achieved by the infusion of factor concentrate at the adequate dose, my recommendation for surgeons is always to have local FG by their side. Local FG appears to be an effective adjunctive therapy for cases in which bleeding is likely (e.g. patients with inhibitors), and for circumcisions, oral surgery, and treatment of pseudotumours. Through the use of local FG, the doses of factor concentrate necessary to prevent bleeding could be reduced, providing considerable cost savings.

In previous studies, 50%-70% of patients referred to orthopedic surgeons for total knee replacement (TKR) were not surgical candidates at the time of initial assessment. The purpose of our study was to identify and cross-validate patient self-reported predictors of suitability for TKR and to determine the clinical utility of a predictive model to guide the timing and appropriateness of referral to a surgeon. We assessed pre-consultation patient data as well as the surgeon's findings and post-consultation recommendations. We used multivariate logistic regression to detect self-reported items that could identify suitable surgical candidates. Patients' willingness to undergo surgery, higher rating of pain, greater physical function, previous intra-articular injections and patient age were the factors predictive of patients being offered and electing to undergo TKR. The application of the model developed in our study would effectively reduce the proportion of nonsurgical referrals by 25%, while identifying the vast majority of surgical candidates (> 90%). Using patient-reported information, we can correctly predict the outcome of specialist consultation for TKR in 70% of cases. To reduce long waits for first consultation with a surgeon, it may be possible to use these items to educate and guide referring clinicians and patients to understand when specialist consultation is the next step in managing the patient with severe osteoarthritis of the knee.

We present the results of surgical correction of pectus excavatum (PE) and pectus carinatum (PC) deformities in adults, and also report a new method of sternal support used in surgery for PE deformities. We present the results of 77 patients between the ages of 10 and 29 years (mean 17) with PE (n = 46) or PC (n = 31) deformities undergoing corrective surgery from 2004 to 2011, using the Ravitch repair method. Symptoms of the patients included chest pain (15%) and tachycardia (8%). Three patients underwent repair of recurrent surgical conditions. All of the patients with dyspnoea with exercise experienced marked improvement at five months post operation. Complications included pneumothorax in 5.1% (n = 4), haemothorax in 2.6% (n = 2), chest discomfort in 57% (n = 44), pleural effusion in 2.6% (n = 2), and sternal hypertrophic scar in 27% (n = 21) of patients. Mean hospitalisation was eight days. Pain was mild and intravenous analgesics were used for a mean of four days. There were no deaths. Results after surgical correction were very good or excellent in 62 patients (80%) at a mean follow up of three years. Three patients had recurrent PE and were repaired with the Nuss procedure. In three patients who underwent the Ravitch procedure, a stainless steel bar was used for sternal support instead of Kirschner wire. Pectus deformities may be repaired with no mortality, low morbidity, very good cosmetic results and improvement in cardiological and respiratory symptoms.

There is significant diversity in the utilization of antibiotics for neonates undergoing surgical procedures. Our institution standardized antibiotic administration for surgical neonates, in which no empiric antibiotics were given to infants with surgical conditions postnatally, and antibiotics are given no more than 72 hours perioperatively. We compared the time periods before and after implementation of antibiotic protocol in an institution review board-approved, retrospective review of neonates with congenital surgical conditions who underwent surgical correction within 30 days after birth. Surgical site infection at 30 days was the primary outcome, and development of hospital-acquired infections or multidrug-resistant organism were secondary outcomes. One hundred forty-eight infants underwent surgical procedures pre-protocol, and 127 underwent procedures post-protocol implementation. Surgical site infection rates were similar pre- and post-protocol, 14% and 9% respectively, (P = .21.) The incidence of hospital-acquired infections (13.7% vs 8.7%, P = .205) and multidrug-resistant organism (4.7% vs 1.6%, P = .143) was similar between the 2 periods. Elimination of empiric postnatal antibiotics did not statistically change rates of surgical site infection, hospital-acquired infections, or multidrug-resistant organisms. Limiting the duration of perioperative antibiotic prophylaxis to no more than 72 hours after surgery did not increase the rate of surgical site infection, hospital-acquired infections, or multidrug-resistant organism. Median antibiotic days were decreased with antibiotic standardization for surgical neonates. Copyright © 2017 Elsevier Inc. All rights reserved.

Presence of intra-operative septal mucosal injuries, the amount of bleeding, arterial blood pressure, operation time as well as the quality of the surgical field and the convenience of finding the correct surgical plane as determined by the surgeon using a 5-point scale were compared between two groups. There were no significant differences for the amount of blood loss, mean arterial pressure, operation time, or scores for convenience of finding the correct surgical plane between the two groups. There was no significant difference for intra-operative simple (P = 0.631) and total (simple+severe) (P = 0.649) septal mucoperichondrial injuries between groups 1 and 2, either. However, severe mucoperichondrial injury rate was higher in the patients infiltrated with lidocaine and adrenaline (P = 0.026), and the quality of the surgical field was worse in the patients injected with normal saline (P = 0.0179). Infiltration of septal mucoperichondrium with lidocaine and adrenaline instead of normal saline was not advantageous in terms of objective parameters tested, including bleeding amount and duration of surgery as well as the of the total mucosal injury rate in septoplasty procedure.

This study addressed three questions: (1) Do adolescents undergoing plastic surgery have a realistic view of their body? (2) How urgent is the psychosocial need of adolescents to undergo plastic surgery? (3) Which relations exist between bodily attitudes and psychosocial functioning and personality? From 1995 to 1997, 184 plastic surgical patients aged 12 to 22, and a comparison group of 684 adolescents and young adults from the general population aged 12 to 22 years, and their parents, were interviewed and completed questionnaires and standardised rating scales. Adolescents accepted for plastic surgery had realistic appearance attitudes and were psychologically healthy overall. Patients were equally satisfied with their overall appearance as the comparison group, but more dissatisfied with the specific body parts concerned for operation, especially when undergoing corrective operations. Patients had measurable appearance-related psychosocial problems. Patient boys reported less self-confidence on social areas than all other groups. There were very few patient-comparison group differences in correlations between bodily and psychosocial variables, indicating that bodily attitudes and satisfaction are not differentially related to psychosocial functioning and self-perception in patients than in peers. We concluded that adolescents accepted for plastic surgery have considerable appearance-related psychosocial problems, patients in the corrective group reporting more so than in the reconstructive group. Plastic surgeons may assume that these adolescents in general have a realistic attitude towards their appearance. are psychologically healthy, and are mainly dissatisfied about the body parts concerned for operation. corrective patients more so than reconstructive patients. Introverted patients may need more attention from plastic surgeons during the psychosocial assessment.

In our practice, the authors found that molding helmet used for plagiocephaly preoperatively, in patients with sagittal synostosis, decreased bathrocephaly, forehead bossing, and improved posterior vertex, as well as Cephalic Index (CI). This prompted us to investigate the impact of preoperative molding helmet in patients with sagittal synostosis. A prospective study was performed on patients undergoing surgical correction of sagittal synostosis, over a 5-year period. Patients were categorized into 2 groups. "No Helmet group" only had surgical correction, and "Helmet group" had preoperative molding helmet, prior to surgical correction. Cephalic Index for the 2 groups was compared using t-test. There were 40 patients in the No Helmet group and 18 patients in the Helmet group. For No Helmet group, mean CI at presentation, immediately preoperative, and postoperatively was 0.70 (±0.045), 0.70 (±0.020), and 0.80 (±0.030), respectively, and for Helmet group, it was 0.69 (±0.023), 0.73 (±0.036), and 0.83 (±0.036), respectively. There was no statistically significant difference between CI of the 2 groups at presentation (P = 0.45). Comparison of postoperative CI did show a statistically significant difference between the groups (P = 0.01). For Helmet group, on comparison of CI at presentation and preoperative CI (after helmet therapy), a statistically significant improvement in CI was observed (P = 0.0004). Our results suggest that preoperative molding helmet can decrease bathrocephaly, forehead bossing, and improve posterior vertex as well as CI, prior to surgery and thus can be used as a valuable adjunct in patients with sagittal synostosis.

There is a need to better assess patient satisfaction and surgical outcomes. The purpose of the current study is to identify how preoperative expectations can impact postsurgical satisfaction among youth with adolescent idiopathic scoliosis undergoing spinal fusion surgery. The present study includes patients with adolescent idiopathic scoliosis undergoing spinal fusion surgery enrolled in a prospective, multicentered registry examining postsurgical outcomes. The Scoliosis Research Society Questionnaire-Version 30, which assesses pain, self-image, mental health, and satisfaction with management, along with the Spinal Appearance Questionnaire, which measures surgical expectations was administered to 190 patients before surgery and 1 and 2 years postoperatively. Regression analyses with bootstrapping (with n=5000 bootstrap samples) were conducted with 99% bias-corrected confidence intervals to examine the extent to which preoperative expectations for spinal appearance mediated the relationship between presurgical mental health and pain and 2-year postsurgical satisfaction. Results indicate that preoperative mental health, pain, and expectations are predictive of postsurgical satisfaction. With the shifting health care system, physicians may want to consider patient mental health, pain, and expectations before surgery to optimize satisfaction and ultimately improve clinical care and patient outcomes. Level I-prognostic study.

In the past, resident physicians have provided care to indigent patients under the supervision of experienced physicians. General consensus exists regarding higher surgical costs of patient care at teaching hospitals. No study has examined the outcomes or the cost basis for resident physicians providing health care to an underserved population. To evaluate the visual results in uninsured patients undergoing cataract surgery performed by resident surgeons at a single institution and to determine the cost-effectiveness of care. A retrospective case series of consecutive uninsured patients undergoing cataract procedures performed by attending-supervised resident physicians at the University of Washington from July 1, 2005, through June 30, 2011. Data obtained included demographic information, preoperative and postoperative best-corrected visual acuity (BCVA) in the eye undergoing the procedure, and surgical complications.We calculated the costs of services rendered and normalized them to 2011 dollars. These data were incorporated into time–trade-off discounted utility values. Data were expressed as mean (SD). One hundred forty-three consecutive patients. Cataract surgical procedures. Costs of the surgical procedure and the utility value associated with the BCVA in the operated-on eye, The mean logMAR preoperative BCVA was 1.09 (0.74) (Snellen equivalent, 20/300). The best-recorded mean postoperative BCVA was 0.24 (0.42) (Snellen equivalent, 20/40), obtained at 3.77 (9.30) months. The final recorded mean BCVA was 0.27 (0.43) (Snellen equivalent, 20/40), obtained at a median (SD) follow-up of 16.32 (17.10) months. Four complications in 3 eyes required a second operation; 15 postoperative laser procedures were performed. The mean health care cost per patient was $3437.24 ($1334.68). Using these data, the mean utility value of cataract surgery in this population was 0.80 (0.12); the quality-adjusted life-years gained, 2.43 (1.87); and the discounted ratio of cost to utility, $1889.16 ($4800.62). These data support the success and cost-effectiveness of supervised, resident-performed cataract surgery in an underserved patient population. This study lends support for continuing this traditional scheme of surgical training and education. Further work must ensure that we remain aware of the balance between education and patient care.

To investigate the necessity, safety and efficacy of transobturator tension-free vaginal tape (TVT-O) for treatment of stress urinary incontinence (SUI) during transvaginal corrective operation of pelvic organ prolapse (POP). From Jan. 2005 to Dec. 2010, 92 patients undergoing transvaginal pelvic reconstruction surgery for correction of POP concomitant TVT-O for treatment of SUI in Department of Obstetrics and Gynecology affiliated to Beijing Chaoyang Hospital as concomitant surgery group were enrolled in this retrospective study matched with 90 patients with mild SUI without SUI surgery as non-concomitant surgery group and 120 patients without SUI as control group.Variable clinical index, clinical efficacy and complications were compared among those three groups. Compared with those in the other two groups, the mean age [(62 ± 11) years] was lower (P = 0.007,0.038), the operation time only slightly increased (12.8 min and 12.9 min respectively) significantly in concomitant TVT-O group. The bleeding loss and the length of staying hospital after operation all exhibited no significant differences within three groups (P > 0.05). The effective rate for SUI was 96.7% (89/92) in concomitant TVT-O group, corrective operation of POP was ineffective for 74.4% (67/90) SUI, 9.2% (11/120) patients presented new SUI in the patients without SUI preoperatively. TVT-O is a simple, safe and effective method in the treatment of SUI, which is more suitable for performing simultaneously during the corrective operation of POP.Efficacy of SUI correction was limited in those patients undergoing only pelvic reconstructive surgery. However, a preventive anti-incontinence procedure is not recommended because of the lower incidence in POP patients without SUI preoperatively.

The purpose of this study was to prospectively analyze the outcomes of patients with anomalous aortic origin of a coronary artery undergoing surgical intervention according to a standardized management algorithm. All patients aged 2 to 18 years undergoing surgical intervention for anomalous aortic origin of a coronary artery between December 2012 and April 2017 were prospectively included. Patients underwent stress nuclear perfusion imaging, stress cardiac magnetic resonance imaging, and retrospectively electrocardiogram-gated computed tomography angiography preoperatively. Patients were cleared for exercise at 3 months postoperatively if asymptomatic and repeat stress nuclear perfusion imaging, stress cardiac magnetic resonance imaging, and computed tomography angiography showed normal results. A total of 44 patients, with a median age of 14 years (8-18 years), underwent surgical intervention: 9 (20%) for the anomalous left coronary artery and 35 (80%) for the anomalous right coronary artery. Surgical procedures included unroofing in 35 patients (80%), translocation in 7 patients (16%), ostioplasty in 1 patient (2%), and side-side-anastomosis in 1 patient (2%). One patient who presented with aborted sudden cardiac death from an anomalous left coronary and underwent unroofing presented 1 year later with a recurrent episode and was found to have an unrecognized myocardial bridge and persistent compression of the coronary requiring reintervention. At last follow-up, 40 patients (91%) are asymptomatic and 4 patients have nonspecific chest pain; 42 patients (95%) have returned to full activity, and 2 patients are awaiting clearance. Surgical treatment for anomalous aortic origin of a coronary artery is safe and should aim to associate the coronary ostium with the correct sinus, away from the intercoronary pillar. After surgery, the majority of patients are cleared for exercise and remain asymptomatic. Longer follow-up is needed to assess the true efficacy of surgery in the prevention of sudden cardiac death.

Purpose. To evaluate the effect of en bloc lateral wall decompression with additional orbital fat resection in terms of exophthalmos reduction and complications. Methods. A retrospective, noncomparative case series study from 1999 to 2011 (chart review) in Graves' orbitopathy (GO) patients. The standardized surgical technique involved removal of the lateral orbital wall including the orbital rim via a lid crease approach combined with additional orbital fat resection. Exophthalmos, diplopia, retrobulbar pressure sensation, and complications were analyzed pre- and postoperatively. Results. A total of 111 patients (164 orbits) with follow-up >3 months were analysed. Mean exophthalmos reduction was 3.05mm and preoperative orbital pressure sensation resolved or improved in all patients. Visual acuity improved significantly in patients undergoing surgery for rehabilitative or vision threatening purposes. Preoperative diplopia improved in 10 patients (9.0%) but worsened in 5 patients (4.5%), necessitating surgical correction in 3 patients. There were no significant complications; however, one patient had slight hollowing of the temporalis muscle around the scar that did not necessitate revision, and another patient with a circumscribed retraction of the scar itself underwent surgical correction. Conclusions. The study confirms the efficiency of en bloc lateral wall decompression in GO in a large series of patients, highlighting the low risk of disturbance of binocular functions and of cosmetic blemish in the temporal midface region.

Without surgical treatment, neonatal hypoplastic left heart syndrome (HLHS) mortality in the first year of life exceeds 90 % and, in spite of improved surgical outcomes, many families still opt for non-surgical management. The purpose of this study was to investigate trends in neonatal HLHS management and to identify characteristics of patients who did not undergo surgical palliation. Neonates with HLHS were identified from a serial cross-sectional analysis using the Healthcare Cost and Utilization Project's Kids' Inpatient Database from 2000 to 2012. The primary analysis compared children undergoing surgical palliation to those discharged alive without surgery using a binary logistic regression model. Multivariate logistic regression was conducted to determine factors associated with treatment choice. A total of 1750 patients underwent analysis. Overall hospital mortality decreased from 35.3 % in 2000 to 22.9 % in 2012. The percentage of patients undergoing comfort care discharge without surgery also decreased from 21.2 to 14.8 %. After controlling for demographics and comorbidities, older patients at presentation were less likely to undergo surgery (OR 0.93, 0.91-0.96), and patients in 2012 were more likely to undergo surgery compared to those in prior years (OR 1.5, 1.1-2.1). Discharge without surgical intervention is decreasing with a 30 % reduction between 2000 and 2012. Given the improvement in surgical outcomes, further dialogue about ethical justification of non-operative comfort or palliative care is warranted. In the meantime, clinicians should present families with surgical outcome data and recommend intervention, while supporting their option to refuse.

Expanding living kidney donor criteria with ex-vivo surgery for renal anomalies

Introduction: Renal transplantation remains the gold standard treatment for end-stage renal disease, with living donor kidneys providing the best outcomes in terms of allograft survival. As the number of patients on the waitlist continues to grow, solutions to expand the donor pool are ongoing. A paradigm shift in the eligibility of donors with renal anomalies has been looked at as a potential source to expand the living donor pool. We sought to determine how many patients presented with anatomic renal anomalies at our transplant centre and describe the ex-vivo surgical techniques used to render these kidneys suitable for transplantation. Methods: A retrospective review was performed of all patients referred for surgical suitability to undergo laparoscopic donor nephrectomy between January 2011 and January 2015. Patient charts were analyzed for demographic information, perioperative variables, urological histories, and postoperative outcomes. Results: 96 referrals were identified, of which 81 patients underwent laparoscopic donor nephrectomy. Of these patients, 11 (13.6%) were identified as having a renal anomaly that could potentially exclude them from the donation process. These anomalies included five patients with unilateral nephrolithiasis, four patients with large renal cysts (>4 cm diameter), one patient with an angiomyolipoma (AML) and one patient with a calyceal diverticulum filled with stones. A description of the ex-vivo surgical techniques used to correct these renal anomalies is provided. Conclusions: We have shown here that ex-vivo surgical techniques can safely and effectively help correct some of these renal anomalies to render these kidneys transplantable, helping to expand the living donor pool.

To assess results of surgical correction of brachycephalic syndrome (including stenotic nares, elongated soft palate, and everted laryngeal saccules) in dogs and determine whether dogs with hypoplastic trachea have a less favorable long-term outcome. Retrospective case series. 62 dogs with brachycephalic syndrome. Medical records from 1991 to 2004 were reviewed for information regarding signalment, clinical signs, diagnosis, surgery, and long-term outcome. Surgical outcome was rated by owners as excellent, good, fair, or poor. Common abnormalities, treatments, and long-term outcomes among the 62 dogs were assessed. Predominantly affected breeds included English Bulldog, Pug, and Boston Terrier. Elongated soft palate was the most common abnormality (54/62 [87.1%] dogs); the most common combination of abnormalities was elongated soft palate, stenotic nares, and everted saccules (16/62 [25.8%] dogs). The English Bulldog was the most common breed for all abnormalities, including elongated soft palate (27/54 [50%] dogs), stenotic nares (14/36 [38.9%] dogs), everted saccules (20/36 [55.6%] dogs), hypoplastic trachea (7/13 [53.9%] dogs), and laryngeal collapse (2/5 [40%]). No dogs had everted saccules alone. Outcome did not differ between dogs under-going staphylectomy by use of laser or scissor resection. Follow-up information was obtained for 34 dogs; 16 (47.1%) had an excellent outcome, and 16 (47.1%) had a good outcome. Overall treatment success rate was 94.2%, and overall mortality rate was 3.2%. Surgical treatment of brachycephalic syndrome in dogs appeared to be associated with a favorable long-term outcome, regardless of age, breed, specific diagnoses, or number and combinations of diagnoses.

Recent developments of spinal instruments allow to address nearly all components of idiopathic scoliosis. Direct vertebral rotation (DVR) maneuver was introduced to correct apical axial vertebral rotation. It is however still not well established how efficiently DVR affects results of scoliosis correction. The object of the study was to evaluate en bloc apical vertebral rotation (DVR) and its impact on coronal and sagittal correction of the spine in patients undergoing surgical scoliosis treatment. Thirty-six consecutive patients who underwent posterior spinal fusion with pedicle screws only constructs for idiopathic scoliosis. Fifteen patients (20 curves) were corrected by rod derotation only and 21 patients (26 curves) had both rod derotation and DVR. Curve measurements were performed on x-rays obtained before and postoperatively-coronal curves, kyphosis (T2-T12, T5-T12). Spine flexibility was assessed on prone bending x-rays. Apical axial rotation was determined on CT scans obtained intraoperatively and postoperatively. Rotation angle (RAsag) was measured according to Aaro and Dahlborn. We observed reduction of RAsag in all patients; however, in DVR group, decrease was greater, by 31.8% comparing to non-DVR group, by 8.6% (p = 0.0003). Mean coronal correction in DVR group was 68.8% and in rod derotation group without DVR 55% (p = 0.002). No significant correlation was found between degree of derotation obtained and coronal correction. In DVR group T2-T12 kyphosis has increased in 28 (65%) patients whereas in non-DVR group in 31 (69%) cases. Mean value of T2-T12 kyphosis growth was 16.7% in DVR and 22.1% in non-DVR group. These differences however did not occur statistically significant. Direct vertebral rotation (DVR) maneuver reduces significantly apical rotation of the spine, enhances ability of coronal correction, and it does not reduce thoracic kyphosis.

This study aims to describe patient demographics, visual and surgical outcomes of a cohort undergoing small incision cataract surgery at a Pacific regional ophthalmic training facility. This is a prospective, longitudinal study conducted at the Pacific Eye Institute, Fiji. One hundred fifty-six patients underwent small incision cataract surgery. Preoperatively, a complete ophthalmic examination, including pachymetry and macular optical coherence tomography performed by two independent investigators. Temporal small incision cataract surgery with intraocular lens insertion was performed by ophthalmologists, and trainee ophthalmologists. Follow-up occurred at day one, four weeks and 3 months. Patient characteristics, visual outcomes including surgically induced astigmatism and complications. Ninety-one per cent (142/156) attended 3-month follow-up with median age 63 years (range 19-82), 52% female (81/156) and 58% (90/156) Fijian ethnicity. In 37% (57/156), the contralateral eye was pseudophakic. Mean preoperative best spectacle-corrected visual acuity was logMAR 1.44 (6/165). At 3 months, 74% (105/142) achieved ≥6/18 unaided vision (94% [133/142] best spectacle-corrected visual acuity). Mean postoperative spherical equivalent was -0.78 (SD 0.95) D and mean surgically induced astigmatism 1.04 (0.57) D. Complications included posterior capsular rupture with vitreous loss (4% [6/156]), optical coherence tomography confirmed macular oedema (8% [12/152] at 4 weeks), significant posterior capsular opacity (23% [31/136]) and >5% increase in preoperative pachymetry (1% [1/142]) at 3 months. Reduction in preoperative best spectacle-corrected visual acuity occurred in 2% (3/142). No cases of endophthalmitis. Small incision cataract surgery provided to a regional population is effective with 94% achieving the World Health Organisation's definition of 'Good Vision' (≥6/18). Refinements in biometric and surgical techniques may allow a greater proportion of patients to achieve good unaided vision. © 2017 Royal Australian and New Zealand College of Ophthalmologists.

Fourteen patients with primary Crohn's disease of the appendix have been seen in a 12 year period. These patients represent 12.8% of the total number undergoing surgical resection because of Crohn's disease. Twenty-three cases of appendiceal Crohn's disease have been previously reported in the literature. A correct preoperative diagnosis is rarely made; the usual diagnosis is that of acute appendicitis or appendiceal abscess. The removed appendix in twelve of our 14 cases had marked thickening of the wall with transmural fibrosis and often with granulomatous inflammation. The enlarged appendix had an external appearance similar to that of ileal Crohn's disease, and we consider a correct surgical diagnosis might be possible with better awareness of its existence. The diagnosis might be suspected earlier when the clinical course of apparent appendicitis is protracted or atypical. Contrary to the previous estimation of high recurrence rate, this series and the cumulative evidence in the literature show a relatively low rate at 14%. The feared fistula formation following the removal of the appendix has not been seen in either our series or the literature. These patients, however, merit long-term follow-up. Images Fig. 7. Fig. 2.

Novel approaches to perioperative surgical care focus on optimizing nutrition, mobility, and pain management to minimize adverse events after surgical procedures. To evaluate the outcomes of an enhanced recovery after surgery (ERAS) program among 2 target populations: patients undergoing elective colorectal resection and patients undergoing emergency hip fracture repair. A pre-post difference-in-differences study before and after ERAS implementation in the target populations compared with contemporaneous surgical comparator groups (patients undergoing elective gastrointestinal surgery and emergency orthopedic surgery). Implementation began in February and March 2014 and concluded by the end of 2014 at 20 medical centers within the Kaiser Permanente Northern California integrated health care delivery system. A multifaceted ERAS program designed with a particular focus on perioperative pain management, mobility, nutrition, and patient engagement. The primary outcome was hospital length of stay. Secondary outcomes included hospital mortality, home discharge, 30-day readmission rates, and complication rates. The study included a total of 3768 patients undergoing elective colorectal resection (mean [SD] age, 62.7 [14.1] years; 1812 [48.1%] male) and 5002 patients undergoing emergency hip fracture repair (mean [SD] age, 79.5 [11.8] years; 1586 [31.7%] male). Comparator surgical patients included 5556 patients undergoing elective gastrointestinal surgery and 1523 patients undergoing emergency orthopedic surgery. Most process metrics had significantly greater changes in the ERAS target populations after implementation compared with comparator surgical populations, including those for ambulation, nutrition, and opioid use. Hospital length of stay and postoperative complication rates were also significantly lower among ERAS target populations after implementation. The rate ratios for postoperative complications were 0.68 (95% CI, 0.46-0.99; P = .04) for patients undergoing colorectal resection and 0.67 (95% CI, 0.45-0.99, P = .05) for patients with hip fracture. Among patients undergoing colorectal resection, ERAS implementation was associated with decreased rates of hospital mortality (0.17; 95% CI, 0.03-0.86; P = .03), whereas among patients with hip fracture, implementation was associated with increased rates of home discharge (1.24; 95% CI, 1.06-1.44; P = .007). Multicenter implementation of an ERAS program among patients undergoing elective colorectal resection and patients undergoing emergency hip fracture repair successfully altered processes of care and was associated with significant absolute and relative decreases in hospital length of stay and postoperative complication rates. Rapid, large-scale implementation of a multidisciplinary ERAS program is feasible and effective in improving surgical outcomes.

Spinal alignment in surgical, multisegmental, transpedicular correction of adolescent idiopathic scoliosis

2012-01-01

Summary The objective of this study was to discuss the variables influencing alignment mechanisms of the spine, with particular consideration of post-surgical alignment in adolescent idiopathic scoliosis. The analysis is based on information currently available in the literature, and on the authors’ own experience, which includes surgical material from over 2200 cases of idiopathic scoliosis. Over 50% of cases of adolescent idiopathic scoliosis are decompensated before surgical treatment. Spinal alignment is most significantly influenced by the position of the pelvis. Surgical restoration of lumbar lordosis is more important than attempting to restore thoracic kyphosis in the sagittal plane. The sagittal profile has an essential impact on spinal alignment. The same curves in the coronal plane can have various 3-dimensional configurations. Clinical difficulties in the assessment of thoracic kyphosis and lumbar lordosis result from the fact that they undergo constant change with age. Thoracic hypokyphosis diagnosed before surgery is a very frequent symptom of curve progression. The presence of proximal (thoraco-thoracic) and distal (thoraco-lumbar) junctional kyphosis is very important for planning the scope of spondylodesis. The natural tendency of the spine for alignment (compensation) after surgery nowadays occurs more naturally by applying derotational forces through pedicle screws, compared to the distraction devices (eg, Harrington rod) used in the past.

To analyse clinical outcomes of three types of pelvic surgery for the correction of female mixed or stress urinary incontinence. Women who underwent surgery for urinary incontinence between January 2000 and June 2010 were included in the study (n = 268). Patients were nonrandomly assigned to undergo colporrhaphy, suspension procedure or sling procedure according to their clinical situation. Perioperative parameters were recorded. Short- (< 5 years) and long-term (5-10 years) success rates were determined for each group. The short- and long-term complete cure rates were significantly lower, and the duration of catheterization significantly longer, in patients who underwent colporrhaphy compared with both other groups, but there were no significant differences between suspension or sling procedures. Sling and suspension procedures were equally effective in this study, and both were preferable to colporrhaphy.

Neurologic sequelae of cardiac surgery in children.

PubMed

Ferry, P C

1987-03-01

Major advances in surgical and cardiopulmonary bypass technology have occurred in the past 30 years. Total correction of previously inoperable congenital cardiac defects is being performed with increasing frequency and in children at progressively younger ages. While the majority of children undergoing cardiac surgery survive without incident, increasing concern is being raised about neurologic sequelae seen in some survivors. Complications such as embolization, hypoxia, inadequate cerebral perfusion, and biochemical disturbances may all lead to brain damage following cardiac surgery. Acute postoperative neurologic problems include seizures, impaired levels of consciousness, focal motor deficits, and movement disorders. Long-term sequelae include language and learning disorders, mental retardation, seizures, and cerebral palsy. Intraoperative cerebral monitoring techniques are as yet imperfect, but their use in combination with meticulous intraoperative and postoperative care currently provides the best means of reducing neurologic morbidity. Future studies should explore other methods of preserving neurologic integrity in children undergoing open heart surgery.

Various barriers exist that preclude individuals from undergoing surgical care in low-income countries. Our study assessed the main barriers in Nepal, and identified individuals most at risk for not receiving required surgical care. A countrywide survey, using the Surgeons OverSeas Assessment of Surgical Need (SOSAS) survey tool, was carried out in 2014, surveying 2,695 individuals with a response rate of 97%. Our study used data from a subset, namely individuals who required surgical care in the last twelve months. Data were collected on individual characteristics, transport characteristics, and reasons why individuals did not undergo surgical care. Of the 2,695 individuals surveyed, 207 individuals needed surgical care at least once in the previous 12 months. The main reasons for not undergoing surgery were affordability (n = 42), accessibility (n = 42) and fear/no trust (n = 34). A factor significantly associated with affordability was having a low education (OR = 5.77 of having no education vs. having secondary education). Living in a rural area (OR = 2.59) and a long travel time to a secondary and tertiary health facility (OR = 1.17 and 1.09, respectively) were some of the factors significantly associated with accessibility. Being a woman was significantly associated with fear/no trust (OR = 3.54). More than half of the individuals who needed surgical care did not undergo surgery due to affordability, accessibility, or fear/no trust. Providing subsidised transport, introducing mobile surgical clinics or organising awareness raising campaigns are measures that could be implemented to overcome these barriers to surgical care.

This case report presents a newly diagnosed congenital factor VII deficiency treated with recombinant activated factor VII (rFVIIa). Congenital factor VII deficiency is a rare autosomal-recessive bleeding disorder that occurs in fewer than 1/500,000 persons. Its presentation can vary from epistaxis to hemarthroses and severe central nervous system bleeding, and correlates poorly with factor VII levels. Our patient had not had a significant hemostatic challenge prior to his presentation and therefore never had any symptomatology suggestive of this disease. He was treated with rFVIIa, and was able to undergo repair of his fractures without bleeding. Case report A 19-year-old African-American male presented to the emergency room after an altercation that resulted in significant trauma. He sustained bilateral mandibular angle fractures and orbital floor fractures, requiring urgent surgical correction. On initial evaluation, he was noted to have a prolonged prothrombin time of 40.1 seconds, with an International Normalized Ratio of 4.0, a normal activated partial thromboplastin time of 29.9 seconds, and a platelet count of 241. After receiving vitamin K and fresh frozen plasma, he was taken to the operating room for a temporary rigid maxillomandibular fixation. A 1:1 mixing study with normal plasma corrected the prothrombin time (decreasing from 40.7 to 14.7 seconds) and a factor VII assay revealed 5% of the normal factor VII level. The patient was diagnosed with congenital factor VII deficiency. Due to his coagulopathy and the extensive surgical correction needed, rFVIIa was administered and surgery was accomplished without hemorrhagic sequelae. Conclusion This case report and review describes a rare congenital disease, the history of rFVIIa use, and its mechanism. rFVIIA use in our patient provided a treatment option that allowed the necessary surgical correction, but further prospective studies on dose optimization would ensure adequate dosing with minimal risk of severe side effects.

To evaluate corneal power distribution using the ray tracing method (corneal power) in eyes undergoing small incision lenticule extraction (SMILE) surgery and compare the functional optical zone with two lenticular sizes. This retrospective study evaluated 128 patients who underwent SMILE for the correction of myopia and astigmatism with a lenticular diameter of 6.5 mm (the 6.5-mm group) and 6.2 mm (the 6.2-mm group). The data include refraction, correction, and corneal power obtained via a Scheimpflug camera from the pupil center to 8 mm. The surgically induced changes in corneal power (Δcorneal power) were compared to correction and Δrefraction. The functional optical zone was defined as the largest ring diameter when the difference between the ring power and the pupil center power was 1.50 diopters or less. The functional optical zone was compared between two lenticular diameter groups. Corneal power distribution was measured by the ray tracing method. In the 6.5-mm group (n=100), Δcorneal power at 5 mm showed the smallest difference from Δrefraction and Δcorneal power at 0 mm exhibited the smallest difference from correction. In the 6.2-mm group (n=28), Δcorneal power at 2 mm displayed the lowest dissimilarity from Δrefraction and Δcorneal power at 4 mm demonstrated the lowest dissimilarity from correction. There was no significant difference between the mean postoperative functional optical zones in either group when their spherical equivalents were matched. Total corneal refactive power can be used in the evaluation of surgically induced changes following SMILE. A lenticular diameter of 6.2 mm should be recommended for patients with high myopia because there is no functional difference in the optical zone. Copyright 2015, SLACK Incorporated.

RapidSplint: virtual splint generation for orthognathic surgery - results of a pilot series.

Within the domain of craniomaxillofacial surgery, orthognathic surgery is a special field dedicated to the correction of dentofacial anomalies resulting from skeletal malocclusion. Generally, in such cases, an interdisciplinary orthodontic and surgical treatment approach is required. After initial orthodontic alignment of the dental arches, skeletal discrepancies of the jaws can be corrected by distinct surgical strategies and procedures in order to achieve correct occlusal relations, as well as facial balance and harmony within individualized treatment concepts. To transfer the preoperative surgical planning and reposition the mobilized dental arches with optimal occlusal relations, surgical splints are typically used. For this purpose, different strategies have been described which use one or more splints. Traditionally, these splints are manufactured by a dental technician based on patient-specific dental casts; however, computer-assisted technologies have gained increasing importance with respect to preoperative planning and its subsequent surgical transfer. In a pilot study of 10 patients undergoing orthognathic corrections by a one-splint strategy, two final occlusal splints were produced for each patient and compared with respect to their clinical usability. One splint was manufactured in the traditional way by a dental technician according to the preoperative surgical planning. After performing a CBCT scan of the patient's dental casts, a second splint was designed virtually by an engineer and surgeon working together, according to the desired final occlusion. For this purpose, RapidSplint, a custom-made software platform, was used. After post-processing and conversion of the datasets into .stl files, the splints were fabricated by the PolyJet procedure using photo polymerization. During surgery, both splints were inserted after mobilization of the dental arches then compared with respect to their clinical usability according to the occlusal fitting. Using the workflow described above, virtual splints could be designed and manufactured for all patients in this pilot study. Eight of 10 virtual splints could be used clinically to achieve and maintain final occlusion after orthognathic surgery. In two cases virtual splints were not usable due to insufficient occlusal fitting, and even two of the traditional splints were not clinically usable. In five patients where both types of splints were available, their occlusal fitting was assessed as being equivalent, and in one case the virtual splint showed even better occlusal fitting than the traditional splint. In one case where no traditional splint was available, the virtual splint proved to be helpful in achieving the final occlusion. In this pilot study it was demonstrated that clinically usable splints for orthognathic surgery can be produced by computer-assisted technology. Virtual splint design was realized by RapidSplint®, an in-house software platform which might contribute in future to shorten preoperative workflows for the production of orthognathic surgical splints.

Surgical navigation systems are currently used to guide the surgeon in the correct alignment of the implant. The aim of this study was to expand the use of navigation systems by proposing a surgical protocol for intraoperative kinematics evaluations during knee arthroplasty. The protocol was evaluated on 20 patients, half undergoing unicondylar knee arthroplasty (UKA) and half undergoing posterior-substituting, rotating-platform total knee arthroplasty (TKA). The protocol includes a simple acquisition procedure and an original elaboration methodology. Kinematic tests were performed before and after surgery and included varus/valgus stress at 0 and 30 degrees and passive range of motion. Both UKA and TKA improved varus/valgus stability in extension and preserved the total magnitude of screw-home motion during flexion. Moreover, compared to preoperative conditions, values assumed by tibial axial rotation during flexion in TKA knees were more similar to the rotating patterns of UKA knees. The analysis of the anteroposterior displacement of the knee compartments confirmed that the two prostheses did not produce medial pivoting, but achieved a postoperative normal behavior. These results demonstrated that proposed intraoperative kinematics evaluations by a navigation system provided new information on the functional outcome of the reconstruction useful to restore knee kinematics during surgery.

The Ravitch procedure is a well-established surgical procedure for correction of chest wall deformities. Sternal wedge osteotomy is an important part of this procedure. We studied the incidence of wedge osteotomy with respect to the type of chest wall deformity in patients undergoing surgical correction with the use of a recently developed chest wall stabilization system. A total of 47 patients, 39 (83%) male and 8 (17%) female with a mean age of 14.9 ± 2.1 years, underwent the Ravitch procedure. Twenty-four (51.1%) had pectus carinatum, 19 (40.4%) had pectus excavatum, and 4 (8.5%) had pectus arcuatum. A conventional or oblique sternal wedge osteotomy was performed as indicated, followed by chest wall stabilization using the MedXpert system. Of the 47 patients, 27 (57.4%) had a sternal wedge osteotomy. All cases of pectus arcuatum and redo cases underwent sternal wedge osteotomy. Pectus excavatum cases tended to have a greater incidence of wedge osteotomy compared to pectus carinatum cases (68.4% vs. 41.7%, p = 0.052). Patients with more resected ribs had a greater rate of wedge osteotomy (63.4%) compared to those with fewer resected ribs (16.7%, p = 0.043). A sternal wedge osteotomy is more commonly performed in patients with pectus excavatum compared to those with pectus carinatum. All redo and pectus arcuatum cases need a wedge osteotomy for proper correction. Wedge osteotomy is very likely in more aggressive corrections with more rib resections. © The Author(s) 2016.

Growing evidence supports the safety of a laparoscopic approach for patients affected by apparent early-stage ovarian cancer. However, no well-designed studies comparing laparoscopic and open surgical staging are available. In the present investigation we aimed to provide a balanced long-term comparison between these 2 approaches. Retrospective study (Canadian Task Force classification II-2). Tertiary center. Data of consecutive patients affected by early-stage ovarian cancer who had laparoscopic staging were matched 1:1 with a cohort of patients undergoing open surgical staging. The matching was conducted by a propensity-score comparison. Laparoscopic and open surgical staging. Fifty patient pairs (100 patients: 50 undergoing laparoscopic staging vs 50 undergoing open surgical staging) were included. Demographic and baseline oncologic characteristics were balanced between groups (p > .2). We observed that patients undergoing laparoscopic staging experienced longer operative time (207.2 [71.6] minutes vs 180.7 [47.0] minutes; p = .04), lower blood loss (150 [52.7] mL vs 339.8 [225.9] mL; p < .001), and shorter length of hospital stay (4.0 [2.6] days vs 6.1 [1.6] days; p < .001) compared with patients undergoing open surgical staging. No conversion to open surgery occurred. Complication rate was similar between groups. No difference in survival outcomes were observed, after a mean (SD) follow-up of 49.5 (64) and 52.6 (31.7) months after laparoscopic and open surgical staging, respectively. Our findings suggest that the implementation of minimally invasive staging does not influence survival outcomes of patients affected by early-stage ovarian cancer. Laparoscopic staging improved patient outcomes, reducing length of hospital stay. Further large prospective studies are warranted. Copyright © 2016 AAGL. Published by Elsevier Inc.

To report the early results of the BYPASS project - the Brazilian registrY of adult Patient undergoing cArdiovaScular Surgery - a national, observational, prospective, and longitudinal follow-up registry, aiming to chart a profile of patients undergoing cardiovascular surgery in Brazil, assessing the data harvested from the initial 1,722 patients. Data collection involved institutions throughout the whole country, comprising 17 centers in 4 regions: Southeast (8), Northeast (5), South (3), and Center-West (1). The study population consists of patients over 18 years of age, and the types of operations recorded were: coronary artery bypass graft (CABG), mitral valve, aortic valve (either conventional or transcatheter), surgical correction of atrial fibrillation, cardiac transplantation, mechanical circulatory support and congenital heart diseases in adults. 83.1% of patients came from the public health system (SUS), 9.6% from the supplemental (private insurance) healthcare systems; and 7.3% from private (out-of -pocket) clinic. Male patients comprised 66%, 30% were diabetics, 46% had dyslipidemia, 28% previously sustained a myocardial infarction, and 9.4% underwent prior cardiovascular surgery. Patients underwent coronary artery bypass surgery were 54.1% and 31.5% to valve surgery, either isolated or combined. The overall postoperative mortality up to the 7th postoperative day was 4%; for CABG was 2.6%, and for valve operations, 4.4%. This first report outlines the consecution of the Brazilian surgical cardiac database, intended to serve primarily as a tool for providing information for clinical improvement and patient safety and constitute a basis for production of research protocols.

To systematically analyze published randomized trials on the effectiveness of preoperative prophylactic antibiotics in patients undergoing breast surgical procedures. Trials on the effectiveness of preoperative prophylactic antibiotics in patients undergoing breast surgery were selected and analyzed to generate summated data (expressed as risk ratio [RR]) by using RevMan 5.0. Nine randomized controlled trials encompassing 3720 patients undergoing breast surgery were retrieved from the electronic databases. The antibiotics group comprised a total of 1857 patients and non-antibiotics group, 1863 patients. There was no heterogeneity [χ(2) = 7.61, d.f. = 7, p < 0.37; I(2) = 8%] amongst trials. Therefore, in the fixed-effects model (RR, 0.64; 95% CI, 0.50-0.83; z = 3.48; p < 0.0005), the use of preoperative prophylactic antibiotics in patients undergoing breast surgical procedures was statistically significant in reducing the incidence of surgical site infection (SSI). Furthermore, in the fixed-effects model (RR, 1.30; 95% CI, 0.89-1.90; z = 1.37; p < 0.17), adverse reactions secondary to the use of prophylactic antibiotics was not statistically significant between the two groups. Preoperative prophylactic antibiotics significantly reduce the risk of SSI after breast surgical procedures. The risk of adverse reactions from prophylactic antibiotic administration is not significant in these patients. Therefore, preoperative prophylactic antibiotics in breast surgery patients may be routinely administered. Further research is required, however, on risk stratification for SSI, timing and duration of prophylaxis, and the need for prophylaxis in patients undergoing breast reconstruction versus no reconstruction. © 2012 Wiley Periodicals, Inc.

To determine the association between race/ethnicity and perioperative outcomes in individuals undergoing major oncologic and nononcologic surgical procedures in the United States. Prior work has shown that there are significant racial/ethnic disparities in perioperative outcomes after several types of major cardiac, general, vascular, orthopedic, and cancer surgical procedures. However, recent evidence suggests attenuation of these racial/ethnic differences, particularly at academic institutions. We utilized the American College of Surgeons National Surgical Quality Improvement Program database to identify 142,344 patients undergoing one of the 16 major cancer and noncancer surgical procedures between 2005 and 2011. Eighty-five percent of the cohort was white, with black and Hispanic individuals comprising 8% and 4%, respectively. In multivariable analyses, black patients had greater odds of experiencing prolonged length of stay after 10 of the 16 procedures studied (all P < 0.05), though there was no disparity in odds of 30-day mortality after any surgery. Hispanics were more likely to experience prolonged length of stay after 5 surgical procedures (all P < 0.04), and were at greater odds of dying within 30 days after colectomy, heart valve repair/replacement, or abdominal aortic aneurysm repair (all P < 0.03). Fewer disparities were observed for Hispanics, than for black patients, and also for cancer, than for noncancer surgical procedures. Important racial/ethnic disparities in perioperative outcomes were observed among patients undergoing major cancer and noncancer surgical procedures at American College of Surgeons National Surgical Quality Improvement Program institutions. There were fewer disparities among individuals undergoing cancer surgery, though black patients, in particular, were more likely to experience prolonged length of stay.

The purpose of this study was to compare the subjective findings of the Epworth Sleepiness Scale (ESS) to the objective findings of the overnight sleep study (OSS) in 57 patients who underwent phase I and phase II surgery for the correction of obstructive sleep apnea (OSA). Forty-two patients in phase I category (hyoid suspension, palatal surgery, and/or genioglossus advancement) and 15 patients in phase II category (maxillomandibular advancement) were examined. All patients had an OSS and completion of an ESS preoperatively and at a minimum of 8 weeks postoperatively. The results of each test were evaluated to examine any relationship between the improvements of the findings of the OSS to the changes in the ESS. Using accepted criteria, phase I surgery produced an 80% success rate and phase II surgery produced a greater than 95% success rate in both the respiratory disturbance index and the ESS. 1) Both phase I and phase II procedures are effective in treating OSA. 2) Phase II appears to be more effective in treating OSA using both objective and subjective evaluations. 3) Improvement in ESS scores and excessive daytime sleepiness seems to parallel the improvement in OSS scores in patients undergoing surgical correction of OSA.

Forced-Air Warmers and Surgical Site Infections in Patients Undergoing Knee or Hip Arthroplasty.

Austin, Paul N

2017-01-01

The majority of the evidence indicates preventing inadvertent perioperative hypothermia reduces the incidence of many perioperative complications. Among the results of inadvertent perioperative hypothermia are increased bleeding, myocardial events, impaired wound healing, and diminished renal function. Most researchers agree there is an increased incidence of surgical site infections in patients who experience inadvertent perioperative hypothermia. Forced-air warming is effective in preventing inadvertent perioperative hypothermia. Paradoxically, forced-air warmers have been implicated in causing surgical site infections in patients undergoing total knee or hip arthroplasty. The results of investigations suggest these devices harbor pathogens and cause unwanted airflow disturbances. However, no significant increases in bacterial counts were found when forced-air warmers were used according to the manufacturer's directions. The results of one study suggested the incidence of surgical site infections in patients undergoing total joint arthroplasty was increased when using a forced-air warmer. However these researchers did not control for other factors affecting the incidence of surgical site infections in these patients. Current evidence does not support forced-air warmers causing surgical site infections in patients undergoing total knee or hip arthroplasty. Clinicians must use and maintain these devices as per the manufacturer's directions. They may consider using alternative warming methods. Well-conducted studies are needed to help determine the role of forced-air warmers in causing infections in these patients.

[Surgical Correction of Scoliosis: Does Intraoperative CT Navigation Prolong Operative Time?

PURPOSE OF THE STUDY The aim of the study was to compare the duration of corrective surgery for scoliosis in relation to the intra-operative use of either fluoroscopic or CT navigation. MATERIAL AND METHODS The indication for surgery was adolescent idiopathic scoliosis in younger patients and degenerative scoliosis in middleage or elderly patients. In a retrospective study, treatment outcomes in 43 consecutive patients operated on between April 2011 and April 2014 were compared. Only patients undergoing surgical correction of five or more spinal segments (fixation of six and more vertebrae) were included. RESULTS Transpedicular screw fixation of six to 13 vertebrae was performed under C-arm fluoroscopy guidance in 22 patients, and transpedicular screws were inserted in six to 14 vertebrae using the O-arm imaging system in 21 patients. A total of 246 screws were placed using the C-arm system and 340 screws were inserted using the O-arm system (p < 0.001). The procedures with use of the O-arm system were more complicated and required an average operative time longer by 48% (measured from the first skin incision to the completion of skin suture). However, the mean time needed for one screw placement (the sum of all surgical procedures with the use of a navigation technique divided by the number of screws placed using this technique) was the same in both techniques (19 min). DISCUSSION With good teamwork (surgeons, anaesthesiologists and a radiologist attending to the O-arm system), the time required to obtain one intra-operative CT scan is 3 to 5 minutes. The study showed that the mean time for placement of one screw was identical in both techniques although the average operative time was longer in surgery with O-arm navigation. The 19- minute interval was not the real placement time per screw. It was the sum of all operative times of surgical procedures (from first incision to suture completion including the whole approach within the range of planned stabilization) which used the same navigation technique divided by the number of all screws inserted during the procedures. The longer average operative time in procedures using O-arm navigation was not related to taking intra-operative O-arm scans. The authors consider surgery with an O-arm imaging system to be a safer procedure and use it currently in surgical correction of scoliosis. CONCLUSIONS The study focused on the length of surgery to correct scoliosis performed using either conventional fluoroscopy (C-arm) or intra-operative CT scanning (O-arm) showed that the mean placement time for one screw was identical in both imaging techniques when six or more vertebrae were stabilised. The use of intra-operative CT navigation did not make the surgery longer, and the higher number of inserted screws provides evidence that this technique is safer and allows us to achieve good stability of the correction procedure. Key words: virtual CT guidance, O-arm, scoliosis, transpedicular screw.

Surgical management of contiguous multilevel thoracolumbar tuberculous spondylitis.

Tuberculous spondylitis (TBS) is the most common form of extra-pulmonary tuberculosis. The mainstay of TBS management is anti-tuberculous chemotherapy. Most of the patients with TBS are treated conservatively; however in some patients surgery is indicated. Most common indications for surgery include neurological deficit, deformity, instability, large abscesses and necrotic tissue mass or inadequate response to anti-tuberculous chemotherapy. The most common form of TBS involves a single motion segment of spine (two adjoining vertebrae and their intervening disc). Sometimes TBS involves more than two adjoining vertebrae, when it is called multilevel TBS. Indications for correct surgical management of multilevel TBS is not clear from literature. We have retrospectively reviewed 87 patients operated in 10 years for multilevel TBS involving the thoracolumbar spine at our spine unit. Two types of surgeries were performed on these patients. In 57 patients, modified Hong Kong operation was performed with radical debridement, strut grafting and anterior instrumentation. In 30 patients this operation was combined with pedicle screw fixation with or without correction of kyphosis by osteotomy. Patients were followed up for correction of kyphosis, improvement in neurological deficit, pain and function. Complications were noted. On long-term follow-up (average 64 months), there was 9.34 % improvement in kyphosis angle in the modified Hong Kong group and 47.58 % improvement in the group with pedicle screw fixation and osteotomy in addition to anterior surgery (p < 0.001). Seven patients had implant failures and revision surgeries in the modified Hong Kong group. Neurological improvement, pain relief and functional outcome were the same in both groups. We conclude that pedicle screw fixation with or without a correcting osteotomy should be added in all patients with multilevel thoracolumbar tuberculous spondylitis undergoing radical debridement and anterior column reconstruction.

To assess the outcome after using the Shaft-Condylar angle (SCA) as intraoperative reference for sagittal plane correction in displaced lateral humeral condyle fractures in children presented 3-weeks after injury. Ten children, with delayed presentation of a displaced lateral humeral condyle fracture and undergoing surgery during 1999-2011, were reviewed. The goal was to obtain a smooth articular surface with an intraoperative SCA of nearly 40° and nearest-anatomical carrying angle. They were allocated into two groups according to the postoperative SCA [Good-reduction group (SCA=30-50°), and Bad-reduction group (SCA<30°, >50°)] and the final outcomes were then compared. All fractures united without avascular necrosis. The Good-reduction group (n=7) showed a significant improvement in final range of motion and functional outcome compared to the Bad-reduction group (n=3) (p=0.02). However, there was no significant difference in pain, carrying angle and overall outcome between both groups. SCA is a possible intraoperative reference for sagittal alignment correction in late presented displaced lateral humeral condyle fractures.

Surgeries to correct congenital heart diseases are increasing in Brazil and worldwide. However, even with the advances in surgical techniques and perfusion, some cases, especially the more complex ones, can develop heart failure and death. A retrospective study of patients who underwent surgery for correction of congenital heart diseases with cardiopulmonary bypass (CPB) in a university tertiary-care hospital that died, showed infarction in different stages of evolution and scattered microcalcifications in the myocardium, even without coronary obstruction. CPB is a process routinely used during cardiac surgery for congenital heart disease. However, CPB has been related to increased endogenous catecholamines that can lead to major injuries in cardiomyocytes. The mechanisms involved are not completely understood. The aim of this study was to evaluate the alterations induced in the β-adrenergic receptors and GRK-2 present in atrial cardiomyocytes of infants with congenital heart disease undergoing surgical repair with CPB and correlate the alterations with functional and biochemical markers of ischemia/myocardial injury. The study consisted of right atrial biopsies of infants undergoing surgical correction in HC-FMRPUSP. Thirty-three cases were selected. Atrial biopsies were obtained at the beginning of CPB (group G1) and at the end of CPB (group G2). Real-time PCR, Western blotting, and immunofluorescence analysis were conducted to evaluate the expression of β 1 , β 2 -adrenergic receptors, and GRK-2 in atrial myocardium. Cardiac function was evaluated by echocardiography and biochemical analysis (N-terminal pro-brain natriuretic peptide (NT-ProBNP), lactate, and cardiac troponin I). We observed an increase in serum lactate, NT-proBNP, and troponin I at the end of CPB indicating tissue hypoxia/ischemia. Even without major clinical consequences in cardiac function, these alterations were followed by a significant increase in gene expression of β 1 and β 2 receptors and GRK-2, suggesting that this is one of the mechanisms responsible for the exacerbated response of cardiomyocytes to circulating catecholamines. These alterations could explain the irreversible myocardial damage and lipid peroxidation of membranes classically attributed to catecholamine excess, observed in some infants who develop heart failure and postoperative death. Although other factors may be involved, this study confirms that CPB acts as a potent inducer of increased gene expression of β- adrenergic receptors and GRK-2, making the myocardium of these infants more susceptible to the effects of circulating endogenous catecholamines, which may contribute to the development of irreversible myocardial damage and death.

Pre-existing cognitive impairment (CI) is emerging as a predictor of poor post-operative outcomes in elderly patients. Little is known about impaired preoperative cognition and outcomes after elective spine surgery in this patient population. The purpose of this study was to assess the prevalence of neuro CI in elderly patients undergoing deformity surgery and its impact on postoperative outcomes. Elderly subjects undergoing elective spinal surgery for correction of adult degenerative scoliosis were enrolled in this study. Pre-operative baseline cognition was assessed using the Saint Louis Mental Status (SLUMS) test. SLUMS consists of 11 questions, which can give a maximum of 30 points. Mild CI was defined as a SLUMS score between 21-26 points, while severe CI was defined as a SLUMS score of ≤20 points. Normal cognition was defined as a SLUMS score of ≥27 points. Complication rates, duration of hospital stay, and 30-day readmission rates were compared between patients with and without baseline CI. Eighty-two subjects were included in this study, with mean age of 73.26±6.08 years. Fifty-seven patients (70%) had impaired cognition at baseline. The impaired cognition group had the following outcomes: increased incidence of one or more postoperative complications (39% vs. 20%), higher incidence of delirium (20% vs. 8%), and higher rate of discharge institutionalization at skilled nursing or acute rehab facilities (54% vs. 30%). The length of hospital stay and 30-day hospital readmission rates were similar between both cohorts (5.33 vs. 5.48 days and 12.28% vs. 12%, respectively). CI is highly prevalent in elderly patients undergoing surgery for adult degenerative scoliosis. Impaired cognition before surgery was associated with higher rates of post-operative delirium, complications, and discharge institutionalization. CI assessments should be considered in the pre-operative evaluations of elderly patients prior to surgery.

Objective. We sought to compare positive surgical margin rates (PSM), estimated blood loss (EBL), and quality of life outcomes (QOL) among perineal (RPP), retropubic (RRP), and robot-assisted laparoscopic (RALP) prostatectomies. Methods. Records from 463 consecutive men undergoing RPP (92), RRP (180), or RALP (191) for clinically localized prostate cancer were retrospectively reviewed. Age, percent tumor volume, Gleason score, stage, EBL, PSM, and QOL using the expanded prostate cancer index composite (EPIC) were compared. Results. PSM were similar when adjusted for stage, grade, and volume. EBL was significantly less in the RALP (189 ml) group compared to both RPP (475 ml) and RRP (999 ml) groups. When corrected for nerve sparing, there were no differences in erectile function and sexual function amongst the three groups. Urinary summary and pad usage scores showed no significant differences. Conclusion. RPP, RRP, and RALP offer similar surgical and QOL outcomes. RALP and RPP demonstrate less EBL compared to RRP. PMID:22111001

We describe the treatment outcomes of patients with bilateral Warthin tumors in the parotid gland according to surgical methods. The medical records of ten patients with bilateral Warthin tumors in the parotid gland who underwent surgery between 2004 and 2011 were retrospectively reviewed. Ten patients were included in the study and 13 parotidectomies were performed. Patients with bilateral Warthin tumors in the parotid gland were divided into three groups according to the surgical methods used to treat these individuals. In group 1, the patients were closely observed without undergoing contralateral parotidectomy after unilateral parotidectomy. In group 2, the patients underwent concurrent bilateral parotidectomies. In group 3, the patient underwent contralateral parotidectomy 2 months after unilateral parotidectomy was performed. The overall rate of transient facial nerve dysfunction was 31%. Our findings suggest that concurrent superficial parotidectomy may be an appropriate method for treating bilateral Warthin tumors in the parotid gland, at least for desired patients. The symptoms of this type of tumor and physical examination findings are frequently non-specific and present in the unilateral parotid gland. Therefore, a high degree of discernment is needed and imaging techniques are essential for the determining the correct pre-operative diagnosis.

Primary hyperparathyroidism is the most common disease in Russian Federation, cured by endocrine surgeons. Health status after surgical correction of primary hyperparathyroidism depends on availability of screening hypercalciemia, which is still absent in our country. Another problem is a model of surgical management of primary hyperparathyroidism (frozen section, intraoperative monitoring of parathyroid hormone, gamma-detection and so on). Although minimally invasive parathyroidectomy has become the only method of treatment in many countries, it is still crucial to identify and accurately localize parathyroid glands before bilateral neck exploration surgery. The diagnostic efficacy of the various imaging techniques is still the subject of current debate. The usefulness of preoperative parathyroid imaging with both dual scintigraphy-single-photon emission computed tomography (SPECT) Tc 99m and high-resolution ultrasonography (US) was studied in 92 patients undergoing operations for primary hyperparathyroidism. The accuracy of "integrated" ultrasonography ("check-up US", "target US" after SPECT) and "intraoperative US") of parathyroid glands was 92.9%, sensitivity - 91% and positive predictive value - 94%. This study supports an algorithm of obtaining "integrated" ultrasonography as the initial and in most cases the only preoperative localization tests for patients with primary hyperparathyroidism.

The choice between endoscopic injection (EI) and ureteroneocystotomy (UNC) for surgical correction of vesicoureteral reflux (VUR) is controversial. To compare postoperative outcomes of EI vs UNC. This study reviewed linked inpatient (SID), ambulatory surgery (SASD), and emergency department (SEDD) data from five states in the United States (2007-10) to identify pediatric patients with primary VUR undergoing EI or UNC as an initial surgical intervention. Unplanned readmissions, additional procedures, and emergency room (ER) visits were extracted. Statistical analysis was performed using multivariate logistic regression using generalized estimating equation (GEE) to adjust for hospital-level clustering. The study identified 2556 UNC and 1997 EI procedures. Compared with patients undergoing EI, those who underwent UNC were more likely to be younger (4.6 vs 6.0 years, P < 0.001), male (30 vs 20%, P < 0.001), and publicly insured (34 vs 29%, P < 0.001). As shown in Summary Figure, compared with EI, UNC patients had lower rates of additional anti-reflux procedures within 12 months (25 (1.0) vs 121 (6.1%), P < 0.001), but a higher rate of 30-day and 90-day readmissions and ER visits. On multivariate analysis, patients treated by UNC remained at higher odds of being readmitted (OR = 4.45; 2.69 in 30 days; 90 days, P < 0.001) and to have postoperative ER visits (OR = 3.33; 2.26 in 30 days; 90 days, P < 0.001); however, EI had significantly higher odds of repeat anti-reflux procedures in the subsequent year (OR = 7.12, P < 0.001). Endoscopic injection constituted nearly half of initial anti-reflux procedures in children. However, patients treated with UNC had significantly lower odds of requiring re-treatment in the first year relative to those treated with EI. By contrast, patients treated with UNC had more than twice the odds of being readmitted or visiting an ER postoperatively. Although the available data were amongst the largest and most well validated, the major limitation was the retrospective nature of the administrative database. The practice setting may not be generalizable to states not included in the analysis. Postoperative readmissions and ER visits were uncommon after any surgical intervention for VUR, but were more common among children undergoing UNC. The EI patients had a more than seven-fold increased risk of surgical re-treatment within 1 year. Copyright © 2017 Journal of Pediatric Urology Company. Published by Elsevier Ltd.

Objective To report the early results of the BYPASS project - the Brazilian registrY of adult Patient undergoing cArdiovaScular Surgery - a national, observational, prospective, and longitudinal follow-up registry, aiming to chart a profile of patients undergoing cardiovascular surgery in Brazil, assessing the data harvested from the initial 1,722 patients. Methods Data collection involved institutions throughout the whole country, comprising 17 centers in 4 regions: Southeast (8), Northeast (5), South (3), and Center-West (1). The study population consists of patients over 18 years of age, and the types of operations recorded were: coronary artery bypass graft (CABG), mitral valve, aortic valve (either conventional or transcatheter), surgical correction of atrial fibrillation, cardiac transplantation, mechanical circulatory support and congenital heart diseases in adults. Results 83.1% of patients came from the public health system (SUS), 9.6% from the supplemental (private insurance) healthcare systems; and 7.3% from private (out-of -pocket) clinic. Male patients comprised 66%, 30% were diabetics, 46% had dyslipidemia, 28% previously sustained a myocardial infarction, and 9.4% underwent prior cardiovascular surgery. Patients underwent coronary artery bypass surgery were 54.1% and 31.5% to valve surgery, either isolated or combined. The overall postoperative mortality up to the 7th postoperative day was 4%; for CABG was 2.6%, and for valve operations, 4.4%. Conclusion This first report outlines the consecution of the Brazilian surgical cardiac database, intended to serve primarily as a tool for providing information for clinical improvement and patient safety and constitute a basis for production of research protocols.

Sleep disturbance is a common complaint of patients with a rotator cuff tear. Inadequate and restless sleep, along with pain, is often a driving symptom for patients to proceed with rotator cuff repair. To date, no studies have examined sleep disturbance in patients undergoing rotator cuff repair, and there is no evidence that surgery improves sleep disturbance. Sleep disturbance is prevalent in patients with a symptomatic rotator cuff tear, and sleep disturbance improves after arthroscopic rotator cuff repair. Case series; Level of evidence, 4. A total of 56 patients undergoing arthroscopic rotator cuff repair for full-thickness tears were enrolled in a prospective study. Patients were surveyed preoperatively and postoperatively at intervals of 2, 6, 12, 18, and 24 weeks. Patient outcomes were scored using the Pittsburgh Sleep Quality Index (PSQI), Simple Shoulder Test (SST), visual analog scale for pain (VAS), and single assessment numeric evaluation (SANE). Demographic and surgical factors were also collected for analysis. Preoperative PSQI scores indicative of sleep disturbance were reported in 89% of patients. After surgery, a statistically significant improvement in PSQI was achieved at 3 months (P = .0012; 91% follow-up) and continued through 6 months (P = .0179; 93% follow-up). Six months after surgery, only 38% of patients continued to have sleep disturbance. Multivariable linear regression of all surgical and demographic factors versus PSQI was performed and demonstrated that preoperative and prolonged postoperative narcotic use negatively affected sleep. Sleep disturbance is common in patients undergoing rotator cuff repair. After surgery, sleep disturbance improves to levels comparable with those of the general public. Preoperative and prolonged postoperative use of narcotic pain medication negatively affects sleep. © 2015 The Author(s).

To evaluate how the introduction of robotic-assisted surgery affects treatment-related morbidity and cost of endometrial cancer (EC) staging. We retrospectively reviewed the records of consecutive patients with stage I-III EC undergoing surgical staging between 2007 and 2012 at our institution. Costs (from surgery to 30days after surgery) were set based on the Medicare cost-to-charge ratio for each year and inflated to 2014 values. Inverse probability weighting (IPW) was used to decrease the allocation bias when comparing outcomes between surgical groups. We focused our analysis on the 251 EC patients who had robotic-assisted surgery and the 384 who had open staging. During the study period, the use of robotic-assisted surgery increased and open staging decreased (P<0.001). Correcting group imbalances by using IPW methodology, we observed that patients undergoing robotic-assisted staging had a significantly lower postoperative complication rate, lower blood transfusion rate, longer median operating time, shorter median length of stay, and lower readmission rate than patients undergoing open staging (all P<0.001). Overall 30-day costs were similar between the 2 groups, with robotic-assisted surgery having significantly higher median operating room costs ($2820 difference; P<0.001) but lower median room and board costs ($2929 difference; P<0.001) than open surgery. Increasing experience with robotic-assisted staging was significantly associated with a decrease in median operating time (P=0.002) and length of stay (P=0.003). The implementation of robotic-assisted surgery for EC staging improves patient outcomes. It provides women the benefits of minimally invasive surgery without increasing costs and potentially improves patient turnover. Copyright © 2016 Elsevier Inc. All rights reserved.

Preoperative non-surgical over-correction of cleft lip nasal deformity.

Alar cartilage, which is elastic like auricular cartilage, is correctable in the early neonatal period. Taking advantage of this correctability, we have performed preoperative non-surgical over-correction for cleft lip nasal deformity of incomplete and complete cleft lips with a Simonart's band. The device for this correction was made by processing a nostril retainer into a nostril over-corrector which utilises a spring of silicone rubber, works like a tissue expander and is supported by the nostril floor. Twenty cases are reviewed whose follow-up lasted more than 19 months. The earlier the non-surgical over-correction began, the more satisfactory were the results that were obtained.

To compare outcomes of anterior-only (AO), posterior-only (PO), and anteroposterior (AP) surgical approaches for treatment of dystrophic cervical kyphosis in patients with neurofibromatosis 1 (NF1). This retrospective observational study included 81 patients with dystrophic cervical kyphosis secondary to NF1. Length of kyphosis, duration of halo traction, Cobb angle, C2-7-sagittal vertical axis (SVA), T1 slope, Neck Disability Index score, and postoperative complications were evaluated before and, if possible, after each surgical approach. AP approach provided the best outcomes (average spinal Cobb angle was corrected from 61.2 ± 9.1° to 5.7 ± 3.2°, P < 0.05); there was no significant difference between AO and PO approaches (P > 0.05). With regard to cervical sagittal balance, AP approach had the most improvements of C2-7-SVA (mean C2-7-SVA was corrected from 3.2 ± 9.2 mm to 12.8 ± 2.6 mm, P < 0.05); the difference between AO and PO approaches was not significant (P > 0.05). T1 slope results were similar to C2-7-SVA. Neck Disability Index score of all patients improved significantly after surgery (P < 0.05); specifically, patients who had an AP approach constituted the largest portion of the satisfied patient group. Postoperative junctional kyphosis occurred in 11 patients (1 AP approach, 6 AO approach, 4 PO approach); these findings correlated with patients with ≤5 fused segments. AP approach surgery provided the best correction of dystrophic cervical kyphosis and sagittal balance for patients with NF1. Patients undergoing an AP approach were more satisfied with their outcomes. Junctional kyphosis can be prevented effectively using an AP approach in patients with >5 fused segments.

The purpose of the study was to evaluate the accuracy of the American College of Surgeons NSQIP Surgical Risk Calculator for predicting risk-adjusted 30-day outcomes for patients undergoing partial nephrectomy (PN) for renal cell carcinoma (RCC). A single institution, multi-surgeon, prospectively maintained database was queried for patients undergoing PN for RCC from 1998 to 2015. 21 preoperative factors were analyzed for each patient with predicted risk for 30-day complications, mortality, and length of stay (LOS) calculated. Differences between the mean predicted risk and observed rate of surgical outcomes were determined using two-sided one-sample t test with significance at p < 0.05. Subgroup analyses of outcomes stratified by surgical approach were also performed. 470 patients undergoing PN for RCC were analyzed. Comparing NSQIP predicted to observed outcomes, clinically significant underestimations occurred with rates of overall complications (9.16 vs. 16.81%, p < 0.001), surgical site infections [SSI] (1.65 vs. 2.77%, p < 0.001), urinary tract infection [UTI] (1.41 vs. 3.40%, p < 0.001), and LOS (3.25 vs. 3.73 days, p < 0.001). On subgroup analysis, 209 open PN and 261 minimally invasive PN (MIPN) were performed. The NSQIP calculator consistently underestimated overall complications, SSI, UTI, and LOS (p < 0.001) among both surgical approaches, while overestimating MIPN severe complications (p < 0.001). Clinically important differences persisted when stratifying the MIPN group by laparoscopic (N = 111) and robotic (N = 150) approaches. The ACS NSQIP Surgical Risk Calculator had significant discrepancies among observed and predicted outcomes. Additional analyses confirmed these differences remained significant irrespective of surgical approach. These findings emphasize the need for urologic oncology-specific calculators to better predict surgical outcomes in this complex patient population.

Pectus excavatum is the most common congenital deformity of the anterior chest wall, in which several ribs and the sternum grow abnormally. Nowadays, the surgical correction is carried out in children and adults through Nuss technic. This technic has been shown to be safe with major drivers as cosmesis and the prevention of psychological problems and social stress. Nowadays, no application is known to predict the cosmetic outcome of the pectus excavatum surgical correction. Such tool could be used to help the surgeon and the patient in the moment of deciding the need for surgery correction. This work is a first step to predict postsurgical outcome in pectus excavatum surgery correction. Facing this goal, it was firstly determined a point cloud of the skin surface along the thoracic wall using Computed Tomography (before surgical correction) and the Polhemus FastSCAN (after the surgical correction). Then, a surface mesh was reconstructed from the two point clouds using a Radial Basis Function algorithm for further affine registration between the meshes. After registration, one studied the surgical correction influence area (SCIA) of the thoracic wall. This SCIA was used to train, test and validate artificial neural networks in order to predict the surgical outcome of pectus excavatum correction and to determine the degree of convergence of SCIA in different patients. Often, ANN did not converge to a satisfactory solution (each patient had its own deformity characteristics), thus invalidating the creation of a mathematical model capable of estimating, with satisfactory results, the postsurgical outcome.

The purpose of our study was to estimate the incidence of SSI (Surgical site infection) and the effect of COLA (contamination, obesity, laparotomy and ASA grade) score on SSI in patients undergoing rectal surgical procedures for rectal cancer. A total of 92 patients who underwent operation for rectum cancer were enrolled in this study. Wound surveillance was performed in all patients by a staff surgeon identified infected wounds during the hospital stay, and collected information for up to 30 days after operation. The overall rate of incisional SSI and organ/space SSI was 22.8% and 7.6% respectively. Surgical site infection rates were 14.2%, 20.58%, 40.7%, 57.1% for COLA 1,2,3 and 4 scores respectively. The area under the receiver/ operator characteristic curve for the score was 0,660. COLA scoring systems predict, with reasonable accuracy, the risk of SSI in rectal cancer patients undergoing elective rectal surgery.

Since the surgery for congenital heart disease (CHD) is considered highly risky, appropriate postoperative care is crucial. After the surgery, children are often discharged with unhealed wounds, incomplete recovery, and continuing pain. Health education programs based on empowerment education model can assist clients to develop skills in self-management. This study aimed to evaluate the effectiveness of an empowerment health education program for improving caregiving knowledge, caring behaviors, and self-efficacy of parents caring for children after corrective surgery for CHD. This prospective clinical trial enrolled pediatric patients undergoing surgical correction for CHD. Patients were divided into two groups: the control group (n = 42), which received the standard education program, and the intervention group (n = 44), which participated in the empowerment theory-based education program. We collected data on left ventricular ejection fraction (LVEF); peripheral oxygen saturation (SpO2); New York Heart Association classification of the patients; and the parents' caregiving knowledge, caring behaviors, and self-efficacy before surgery and one month and three months after surgery. At one month and three months after surgery, the intervention group scored higher than the control group in caregiving knowledge, caring behavior, and self-efficacy. By the third month after surgery, the intervention group had significantly higher values of LVEF and SpO2 than the control group. © The Author(s) 2015.

Although pre-surgical orthodontic treatment has been accepted as a necessary process for stable orthognathic correction in the traditional orthognathic approach, recent advances in the application of miniscrews and in the pre-surgical simulation of orthodontic management using dental models have shown that it is possible to perform a surgery-first orthognathic approach without pre-surgical orthodontic treatment. This prospective study investigated the surgical outcomes of patients with diagnosed skeletal class III dentofacial deformities who underwent orthognathic surgery between December 2007 and December 2014. Cephalometric landmark data for patients undergoing the surgery-first approach were analyzed in terms of postoperative changes in vertical and horizontal skeletal pattern, dental pattern, and soft tissue profile. Forty-five consecutive Asian patients with skeletal class III dentofacial deformities who underwent surgery-first orthognathic surgery and 52 patients who underwent conventional two-jaw orthognathic surgery were included. The analysis revealed that the total treatment period for the surgery-first approach averaged 14.6 months, compared with 22.0 months for the orthodontics-first approach. Comparisons between the immediate postoperative and preoperative and between the postoperative and immediate postoperative cephalometric data revealed factors that correlated with the total treatment duration. The surgery-first orthognathic approach can dramatically reduce the total treatment time, with no major complications. Copyright © 2016 International Association of Oral and Maxillofacial Surgeons.

Westerdahl, Johan; Bergenfelz, Anders

2006-06-01

A sufficient decline in levels of parathyroid hormone measured intraoperatively (ioPTH) precludes early and late surgical failures. A case series of consecutive patients undergoing parathyroidectomy with ioPTH measurement. A university hospital. Two hundred sixty-nine consecutive patients with sporadic primary hyperparathyroidism who underwent first-time parathyroid surgery with ioPTH measurement were followed up for as long as 10 years after surgery. Data on all patients have been collected in a prospective database. Surgical failures up to 10 years after parathyroid surgery. With an average follow-up of 3.6 years (range, 6-120 months), the overall cure rate was 96%. The ioPTH level correctly predicted long-term outcome in 248 (92%) of 269 patients. Six patients had a false-positive ioPTH finding. Five of these patients were found to have germline mutations in the gene for multiple endocrine neoplasia. The remaining patient has not undergone genetic testing. The mutations have rarely (n = 1) or never (n = 4) been described before, to our knowledge. Intraoperative measurement of PTH level has a high overall accuracy with a mean follow-up of 3.6 years. However, among the late surgical failures with false-positive ioPTH findings, overlooked mutations in the multiple endocrine neoplasia gene should be suspected, and therefore genetic analyses in these patients are of great importance.

The purpose of this study was to investigate postoperative analgesic effect of ropivacaine administered as main or supplemental injection for the inferior alveolar nerve block (IANB) in patients undergoing lower third molar surgery. The double-blind randomized study comprised 72 healthy patients. All patients received two blocks, the IANB for surgical procedure + IANB after surgery for postoperative pain control, and were divided into three groups: (1) 2 % lidocaine/epinephrine + 1 % ropivacaine, (2) 2 % lidocaine/epinephrine + saline, and (3) 1 % ropivacaine + saline. The occurrence of postoperative pain, pain intensity and analgesic requirements were recorded. Data were statistically analyzed using chi-square, Fisher, and Kruskal-Wallis tests and analysis of variance (ANOVA) with Bonferroni and Tukey correction. Ropivacaine was more successful than lidocaine/epinephrine in obtaining duration of postoperative analgesia, reduction of pain, and analgesic requirements whether ropivacaine was used for surgical block or administered as a supplemental injection after surgery. Ropivacaine (1 %, 2 ml) resulted in effective postoperative analgesia after lower third molar surgery. Since pain control related to third molar surgery requires the effective surgical anesthesia and postoperative analgesia, the use of 1 % ropivacaine could be clinically relevant in a selection of appropriate pain control regimen for both surgical procedure and early postsurgical treatment.

Adolescent idiopathic scoliosis (AIS) may lead to physical and mental problems. It also can adversely affect patient satisfaction and the quality of life. In this study, we assessed the outcomes and satisfaction rate after surgical treatment of AIS using scoliosis research society-30 questionnaire (SRS-30). We enrolled 135 patients with AIS undergoing corrective surgery. Patients were followed for at least 2 years. We compared pre- and post-operative x-rays in terms of Cobb's angles and coronal balance. At the last visit, patients completed the SRS-30 questionnaire. We then assessed the correlation between radiographic measures, SRS-30 total score, and patient satisfaction. Cobb's angle and coronal balance improved significantly after surgery (P<0.001). The scores of functional activity, pain, self-image/cosmesis, mental health, and satisfaction were 27±4.3, 26±2.5, 33±5.2, 23±3.5, and 13±1.8, respectively. The total SRS-30 score was 127±13. Radiographic measures showed significant positive correlation with satisfaction and SRS-30 total scores. There was also a positive correlation between satisfaction and self-image/cosmesis domain scores. The greater the radiographic angles were corrected the higher the SRS-30 total score and patient satisfaction were. It is intuitive that the appearance and cosmesis is of most important factor associated with patient satisfaction.

There is an ongoing debate regarding the optimal instrument for scalp incisions: the scalpel or electrocautery. The argument generally focuses on improved healing after an incision made with a knife and decreased bleeding when using electrocautery. This study compares the use of scalpel and electrocautery in making coronal incisions for patients undergoing surgical correction of craniosynostosis. The outcome metric used is wound healing within 6 months after surgery. All patients presenting to the University of North Carolina Children's Hospital with craniosynostosis between July 1, 2007 and January 1, 2010 requiring a coronal incision for surgical correction were prospectively enrolled. In all of these patients, half of the coronal incision was made with knife; the other half, with needle tip cautery. Side of the incision was specified at the time of surgery in the operative report. Patients were excluded from the study if the instrument for incision was not specified or if only 1 modality was used for the entire incision. Sixty-eight patients underwent cranial vault reconstruction, of which 58 met inclusion criteria. Of the 58 matched pairs, 55 were analyzed statistically. The 3 excluded cases were those who had midline complications. There were 17 wound complications (15%): 8 in the knife group, 6 in the cautery group, and 3 at midline (with indeterminate side for the problem). We found no statistically significant difference in wound healing between incisions made with a knife or with electrocautery.

Objective To determine if the introduction of a systematic preoperative sinus computed tomography (CT) checklist improves identification of critical anatomic variations in sinus anatomy among patients undergoing endoscopic sinus surgery. Study Design Single-blinded prospective cohort study. Setting Tertiary care hospital. Subjects and Methods Otolaryngology residents were asked to identify critical surgical sinus anatomy on preoperative CT scans before and after introduction of a systematic approach to reviewing sinus CT scans. The percentage of correctly identified structures was documented and compared with a 2-sample t test. Results A total of 57 scans were reviewed: 28 preimplementation and 29 postimplementation. Implementation of the sinus CT checklist improved identification of critical sinus anatomy from 24% to 84% correct ( P < .001). All residents, junior and senior, demonstrated significant improvement in identification of sinus anatomic variants, including those not directly included in the systematic review implemented. Conclusion The implementation of a preoperative endoscopic sinus surgery radiographic checklist improves identification of critical anatomic sinus variations in a training population.

Cirrhotic patients waiting for liver transplantation who need dental extractions are given fresh frozen plasma and/or platelets to correct coagulopathy. This is costly and may be associated with transfusion reactions and fluid overload. We evaluated the efficacy of intranasal desmopressin as an alternative to transfusion to correct the coagulopathy of cirrhotic patients undergoing dental extraction. Cirrhotic patients with platelet counts of 30,000 to 50,000/microL and/or international normalized ratio (INR) 2.0 to 3.0 were enrolled in a prospective, controlled, randomized clinical trial. Blood transfusion (fresh frozen plasma 10 mL/kg and/or 1 unit of single donor platelets, respectively) or intranasal desmopressin (300 microg) were given before dental extraction. A standard oral and maxillofacial surgical treatment protocol was performed by the same surgeon. Patients were followed for postextraction bleeding and side-effects over the next 24 to 48 hours. No significant differences were noted between the 2 groups in gender, age, INR, platelet count, creatinine, total bilirubin, ALT, albumin, MELD score, or number of teeth removed (median 3 vs 4). The number of teeth removed ranged between 1 and 31 in the desmopressin group and 1 and 22 in the transfusion group. No patients in desmopressin group required rescue blood transfusion after extraction. One patient in the transfusion group had bleeding after the procedure and required an additional transfusion. Another patient experienced an allergic reaction at the end of transfusion, which was effectively treated with diphenhydramine. Treatment associated average costs were lower for desmopressin ($700/patient) compared with transfusion ($1,173/patient). Intranasal desmopressin was as effective as blood transfusion in achieving hemostasis in cirrhotic patients with moderate coagulopathy undergoing dental extraction. Intranasal desmopressin was much more convenient, less expensive, and well tolerated.

In a previous report, we described a method of reconstruction using tumor-bearing autograft treated by liquid nitrogen for malignant bone tumor. Here we present the first case of bone deformity correction following a tumor-bearing frozen autograft via three-dimensional computerized reconstruction after multiple surgeries. A 16-year-old female student presented with pain in the left lower leg and was diagnosed with a low-grade central tibial osteosarcoma. Surgical bone reconstruction was performed using a tumor-bearing frozen autograft. Bone union was achieved at 7 months after the first surgical procedure. However, local tumor recurrence and lung metastases occurred 2 years later, at which time a second surgical procedure was performed. Five years later, the patient developed a 19° varus deformity and underwent a third surgical procedure, during which an osteotomy was performed using the Taylor Spatial Frame three-dimensional external fixation technique. A fourth corrective surgical procedure was performed in which internal fixation was achieved with a locking plate. Two years later, and 10 years after the initial diagnosis of tibial osteosarcoma, the bone deformity was completely corrected, and the patient's limb function was good. We present the first report in which a bone deformity due to a primary osteosarcoma was corrected using a tumor-bearing frozen autograft, followed by multiple corrective surgical procedures that included osteotomy, three-dimensional external fixation, and internal fixation.

To measure cardiopulmonary variables, including cardiac index, in dogs with naturally acquired gastric dilatation-volvulus (GDV). Prospective clinical study. 6 dogs with GDV. In addition to typical medical and surgical management of GDV, the dorsal metatarsal and pulmonary arteries and right atrium of the dogs were catheterized to obtain cardiopulmonary measurements before and during anesthesia and surgery. All dogs underwent gastropexy but none required gastrectomy. Mean cardiac index and mean arterial blood pressure for this small population of dogs with GDV were not significantly different from those reported for clinically normal awake or anesthetized dogs. Dogs with naturally acquired GDV without gastric necrosis may not have the classic characteristics, including decreased cardiac index and hypotension, of hypovolemic circulatory shock.

Spinal kyphotic deformity occasionally results in gastroesophageal reflux disease (GERD). The effects of acid reflux on the esophagus in kyphotic patients are unclear, however, and it is unknown whether acid reflux, endoscopic GERD, and reflux-related symptoms improve following surgical spinal correction in these patients. Herein, we investigated the characteristics of GERD in kyphotic patients and the improvement in GERD following surgical correction. In 48 patients with severe kyphotic deformity scheduled for surgical spinal correction, we conducted esophagogastroduodenoscopy, 24-h pH monitoring and three questionnaire surveys, including the frequency scale for the symptoms of GERD (FSSG). We repeated these measurements after surgical correction and compared pre- and post-surgery values. Of 48 patients, 70.8% [95% CI: 55.9-83.0%, 34/48] had endoscopically evaluated esophageal mucosal injury. Regarding pH before surgery, 64.9% (CI: 47.5-79.8%, 24/37) had abnormal acid reflux (intraesophageal pH < 4 more than 5% of the time). FSSG score was significantly associated with the severity of GERD, and the positive rate was 52.6% (CI: 35.8-69.0%, 20/38). Following surgical correction, esophageal mucosal injury improved endoscopically in 90% of patients, and median total FSSG score significantly decreased from 8 (0-30) to 5 (0-19) (P = 0.005). Regarding pH after surgery, prevalence of abnormal acid reflux decreased from 66.7% (95% CI: 41.0-86.7%) to 33.3% (95% CI: 13.3-59.0%) (P = 0.045). Surgical spinal correction in kyphosis patients improves not only kyphotic deformity-related disorders but also esophageal mucosal injury, abnormal acid reflux, and reflux-related symptoms. © 2015 Japan Gastroenterological Endoscopy Society.

Ventriculoperitoneal Shunt Fracture Following Application of Halo-Gravity Traction: A Case Report.

Blakeney, William G; D'Amato, Charles

2015-09-01

Ventriculoperitoneal (VP) shunt malfunctions are very common, and shunt fracture is one of the most common causes. Shunt fractures are often a result of calcification and tethering, which predispose the tubing to fracture when mechanical stresses are applied. This case report describes a case of shunt fracture following application of halo-gravity traction for correction of spinal deformity. Chart and imaging data for a single case were reviewed and reported in this retrospective case study. A 10-year-old female, being treated for syndromic scoliosis, underwent posterior surgical release and application of halo-gravity traction. Increasing weight of traction was applied over a period of 6 weeks, for gradual deformity correction. It was noted on the 6-week cervical spine radiograph that the VP shunt had fractured at the base of the neck. The patient was taken to the operating room and intraoperative findings confirmed shunt fracture. This was repaired without complications. This case, to our best knowledge, is the first reported occurrence of shunt fracture following application of halo-gravity traction. It demonstrates the importance of careful monitoring of patients with VP shunts, when they are undergoing traction for correction of spinal deformity. Level IV.

A retrospective review of prospective data OBJECTIVE:: The purpose of this study was to compare operative and nonoperative patients with similar curve magnitudes to determine motivating factors associated with surgical correction in "smaller" curves. Despite traditional treatment recommendations on major curve angle measurements, many patients with thoracolumbar/lumbar (TH/L) curves of smaller magnitudes are unhappy and desire correction. A prospectively enrolled multicenter adolescent idiopathic scoliosis database was queried. Patients with major TH/L curves <50 degrees and low risk of progression (Risser 3, 4, and 5) were identified and grouped based on their treatment (operative vs. nonoperative). Preoperative demographic, radiographic, Scoliosis Research Society (SRS) outcome scores, and trunk shape values were compared. A total of 126 patients undergoing surgical intervention and 17 patients pursuing nonoperative treatment were analyzed. The average lumbar curve of the operative group was 43 degrees (range, 35 to 49 degrees) and for the nonoperative group was 39 degrees (range, 26 to 49 degrees). The operative group was significantly younger, had larger lumbar major curve angles, lower thoracic to lumbar curve ratio, increased TH/L apical translation, and greater trunk shift (P<0.05). Only lumbar curve (P=0.018, OR=1.19) and trunk shift (P=0.01, OR=3.22) remained significant predictors of surgery in a multivariate regression analysis. SRS scores were significantly lower in the operative group for pain, self-image, function, mental health, and total (P<0.05). When SRS total score was entered into the regression, it was the only significant predictor of surgical intervention (P=0.004, OR=0.03). Many patients with smaller lumbar curves have clinical deformities that are more consistent with larger curves. These smaller curves can produce similar coronal imbalance and trunk shift, with lower SRS domains that may drive patients to seek surgical treatment. What is unclear is the reason for this greater degree of imbalance in this select group of patients and whether the natural history is different for a more balanced TH/L curve. Level II-Prognostic.

Prophylactic antibiotics to prevent surgical site infection after breast cancer surgery.

Surgery has been used as part of breast cancer treatment for centuries; however any surgical procedure has the potential risk of infection. Infection rates for surgical treatment of breast cancer are documented at between three and 15%, higher than average for a clean surgical procedure. Pre and peri-operative antibiotics have been found to be useful in lowering infection rates in other surgical groups, yet there is no current consensus on prophylactic antibiotic use in breast cancer surgery. To determine the effects of prophylactic antibiotics on the incidence of surgical site infection after breast cancer surgery. We searched the Cochrane Wounds and Breast Cancer Groups Specialised Registers, the Cochrane Central Register of Controlled Trials (CENTRAL) issue 1 2006. MEDLINE 2002-2005, EMBASE 1980-2005, NRR issue 1 2005, CINAHL 1982-2004 and SIGLE 1976-2004. Companies and experts in the field were contacted and reference lists were checked. No language restrictions were applied. Randomised controlled trials of pre and peri-operative antibiotics for patients undergoing surgery for breast cancer were included. Primary outcomes were, incidence of breast wound infection and adverse reactions to treatment. Two authors independently examined the title and abstracts of all studies identified by the search strategy, then assessed study quality and extracted data from those that met the inclusion criteria. Six studies met the inclusion criteria. All six evaluated pre-operative antibiotic compared with no antibiotic or placebo. Pooling of the results demonstrated that prophylactic antibiotics significantly reduce the incidence of surgical site infection for patients undergoing breast cancer surgery without reconstruction (pooled RR 0.66, 95% CI, 0.48 to 0.89). No studies presented separate data for patients who underwent reconstructive surgery at the time of removal of the breast tumour. Prophylactic antibiotics reduce the risk of surgical site infection in patients undergoing surgery for breast cancer. The potential morbidity caused by infection, such as delays in wound healing or adjuvant cancer treatments must be balanced against the cost of treatment and potential adverse effects such as drug reactions or increased bacterial resistance. Further studies of patients undergoing immediate breast reconstruction would be useful as studies have identified this group as being at higher risk of infection than those who do not undergo immediate breast reconstruction.

Surgical resection can be an option for the treatment of metastatic liver tumors originating from gastric cancer; however, its prognostic impact is controversial. The aim of this study was to identify prognostic factors in patients with surgical resection of liver metastasis from gastric cancer. We retrospectively analyzed the clinicopathological features of 38 consecutive patients undergoing hepatectomy for metastatic tumors from gastric cancer in our institution between 1990 and 2014. The median overall survival of the patients was 28 months. The 5-year survival rate was 33.9%. Primary tumors of a mixed histological type, and residual tumors during the course of treatment were identified as significant independent poor prognostic factors. Histological evaluation of primary tumors may aid to identify patients suitable for undergoing surgical resection of liver metastasis from gastric cancer. © 2017 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

Real-time transrectal ultrasound guidance during laparoscopic radical prostatectomy: impact on surgical margins.

We evaluated whether intraoperative real-time TRUS navigation during LRP can decrease the incidence of positive surgical margins. Since March 2001, 294 patients with clinically organ confined prostate cancer undergoing LRP have been retrospectively divided into 2 groups, including group 1-217 who underwent LRP without TRUS from March 2001 to February 2003 and group 2-77 who have undergone LRP with TRUS since March 2003. Various baseline parameters were similar between the groups. Before March 2001 the senior surgeon had already performed more than 50 cases of LRP, thus, gaining reasonable familiarity with the technique. Compared to group 1, group 2 had a significantly decreased rate of positive surgical margins in patients with pT3 disease (57% vs 18%, p = 0.002). Positive margin rates also decreased in our overall experience (29% vs 9%, p = 0.0002). Intraoperative TRUS correctly predicted pT2 and pT3 disease in 85% and 86% of patients, respectively. Of the 54 TRUS visualized hypoechoic lesions at sites corresponding to biopsy proven cancer extracapsular extension was suspected in 31, leading to a real-time recommendation of calibrated wider, site specific dissection to achieve negative surgical margins. Intraoperative TRUS monitoring during LRP allows individualized, precise dissection tailored to the specific prostate contour anatomy, thus, compensating for the muted tactile feedback of laparoscopy. In what is to our knowledge the initial experience real-time TRUS guidance significantly decreased the incidence of positive surgical margins during LRP. In the future this concept of rectum based, intraoperative real-time navigation may facilitate a more sophisticated performance of radical prostatectomy.

Patients with genetic susceptibility to breast and ovarian cancer are eligible for risk-reduction surgery. Surgical morbidity of risk-reduction mastectomy (RRM) with concurrent bilateral salpingo-oophorectomy (BSO) is unknown. Outcomes in these patients were compared to patients undergoing RRM without BSO using a large multi-institutional database. A retrospective cohort analysis was conducted using the American College of Surgeon's National Surgical Quality Improvement Program (NSQIP) 2007-2016 datasets, comparing postoperative morbidity between patients undergoing RRM with patients undergoing RRM with concurrent BSO. Patients with genetic susceptibility to breast/ovarian cancer undergoing risk-reduction surgery were identified. The primary outcome was 30-day postoperative major morbidity. Secondary outcomes included surgical site infections, reoperations, readmissions, length of stay, and venous thromboembolic events. A multivariate analysis was performed to determine predictors of postoperative morbidity and the adjusted effect of concurrent BSO on morbidity. Of the 5470 patients undergoing RRM, 149 (2.7%) underwent concurrent BSO. The overall rate of major morbidity and postoperative infections was 4.5% and 4.6%, respectively. There was no significant difference in the rate of postoperative major morbidity (4.5% vs 4.7%, p = 0.91) or any of the secondary outcomes between patients undergoing RRM without BSO vs. those undergoing RRM with concurrent BSO. Multivariable analysis showed Body Mass Index (OR 1.05; p < 0.001) and smoking (OR 1.78; p = 0.003) to be the only predictors associated with major morbidity. Neither immediate breast reconstruction (OR 1.02; p = 0.93) nor concurrent BSO (OR 0.94; p = 0.89) were associated with increased postoperative major morbidity. This study demonstrated that RRM with concurrent BSO was not associated with significant additional morbidity when compared to RRM without BSO. Therefore, this joint approach may be considered for select patients at risk for both breast and ovarian cancer.

This article reviews the pathophysiology of scleroderma (systemic sclerosis [SSc]) and its destructive effects on the mandible in general and the temporomandibular joint (TMJ) in particular. It discusses the considerations of operating on patients with devastating chronic disease and presents 2 cases of TMJ reconstruction in patients with the diagnosis. Two patients with different degrees of SSc involvement underwent TMJ reconstruction with costochondral grafts. The patients represent the surgical considerations pertinent to this disease and different outcomes as determined by the variance in severity of their afflictions. The 2 patients tolerated the surgeries well and exhibited improvement in function in the long-term. One patient thrives and continues to do well despite her SSc approximately 10 years postoperatively; the second patient died of her disease approximately 9 years after her initial surgical care. The experience with these 2 cases showed that patients with SSc can safely undergo TMJ reconstruction with anticipated good results, but that the overall severity of the disease remains paramount in determining the feasibility of corrective surgery under this diagnosis.

Traditionally, maxillofacial deformities are corrected surgically after an initial orthodontic treatment phase. However in, this article, the authors emphasize the postsurgical therapeutic protocol which is extremely important for determining the final and permanent retention of the corrected occlusion. A 55 year old female with severe skeletal Class II malocclusion is presented. Combined surgical and orthodontic correction of the malocclusion was used. : The step-by-step procedure the authors followed for the postsurgical therapy is described. The goals of the postoperative therapy were to restore and rehabilitate neuromuscular function, obtain occlusal stabilization, grind teeth selectively, and final occlusion retention. The importance of a surgical occlusal splint for rehabilitating stomatognathic neuromuscular function postoperatively was demonstrated. Furthermore, the orthodontic-prosthodontic treatment ensured occlusion stability after the surgical correction. The long-term results confirmed the efficacy of the treatment protocol presented here from both functional and aesthetical perspectives. Postsurgical orthodontic treatment is an important step in the surgical and orthodontic therapy of maxillofacial deformities.

Malunion is the most common complication of distal radius fracture. It has previously been demonstrated that there is a correlation between the quality of anatomical correction and overall wrist function. However, surgical correction can be difficult because of the often complex anatomy associated with this condition. Computer assisted surgical planning, combined with patient-specific surgical guides, has the potential to improve pre-operative understanding of patient anatomy as well as intra-operative accuracy. For patients with malunion of the distal radius fracture, this technology could significantly improve clinical outcomes that largely depend on the quality of restoration of normal anatomy. Therefore, the objective of this study is to compare patient outcomes after corrective osteotomy for distal radius malunion with and without preoperative computer-assisted planning and peri-operative patient-specific surgical guides. This study is a multi-center randomized controlled trial of conventional planning versus computer-assisted planning for surgical correction of distal radius malunion. Adult patients with extra-articular malunion of the distal radius will be invited to enroll in our study. After providing informed consent, subjects will be randomized to two groups: one group will receive corrective surgery with conventional preoperative planning, while the other will receive corrective surgery with computer-assisted pre-operative planning and peri-operative patient specific surgical guides. In the computer-assisted planning group, a CT scan of the affected forearm as well as the normal, contralateral forearm will be obtained. The images will be used to construct a 3D anatomical model of the defect and patient-specific surgical guides will be manufactured. Outcome will be measured by DASH and PRWE scores, grip strength, radiographic measurements, and patient satisfaction at 3, 6, and 12 months postoperatively. Computer-assisted surgical planning, combined with patient-specific surgical guides, is a powerful new technology that has the potential to improve the accuracy and consistency of orthopaedic surgery. To date, the role of this technology in upper extremity surgery has not been adequately investigated, and it is unclear whether its use provides any significant clinical benefit over traditional preoperative imaging protocols. Our study will represent the first randomized controlled trial investigating the use of computer assisted surgery in corrective osteotomy for distal radius malunions. NCT01193010.

To analyze early postoperative period in patients with diffuse pulmonary emphysema after palliative surgical correction of respiratory failure. The study included 196 patients who underwent bullectomy (n=111) and surgical reduction of pulmonary volume (n=85). Overall morbidity and mortality were 40.8% and 12.2% respectively. Among patients older than 60 years these values were significantly higher (58.0% and 22.6% respectively). It was shown that age over 60 years is associated with high risk of complications and mortality after excision of large and giant bulls. In patients <60 years morbidity is comparable after bullectomy and surgical reduction of pulmonary volume. Selection of patients for palliative surgical correction of respiratory failure is generally corresponded to that for lung transplantation. However, these methods should be considered complementary rather competing.

Background Malignant pleural mesothelioma (MPM) continues to be a distressing tumor due to its aggressive biologic behavior and scanty prognosis. Several therapeutic approaches have been tested both in clinical and preclinical settings, being intrapleural chemotherapy one of the most promising. Some years ago, our interest focused on polymeric films loaded with cisplatin for the adjuvant intrapleural treatment of surgical patients. After in vitro and in vivo studies in a rat recurrence model of MPM, the aim of this study was to evaluate the pharmacokinetics of the polymeric films in a sheep model in view of further studies in a clinical setting. Methods An ovine model was used. Animals were divided into four groups according to pharmacologic treatment: control group (three animals undergoing left pneumonectomy and saline-NaCl solution); intrapleural hyaluronate cisplatin films (HYALCIS) group (six animals undergoing left pneumonectomy and intrapleural application of polymeric films loaded with cisplatin); intrapleural cisplatin solution (six animals undergoing left pneumonectomy and intrapleural application of cisplatin solution); intravenous cisplatin (five animals undergoing left pneumonectomy and intravenous administration of cisplatin solution). The primary objective was the plasmatic and pleural concentration of cisplatin in the treatment groups. The secondary objective was the treatment-related toxicity evaluated by plasmatic analysis performed at prearranged time intervals and histological examinations of tissue samples collected during animal autopsy. Analysis of variance (ANOVA) was used for statistical analysis. Bonferroni correction was applied for comparison between all groups. Results Twenty female Sardinian sheep with a mean weight of 45.1 kg were studied. All animals survived the surgical procedures. The whole surgical procedure had a mean duration of 113 minutes. Cisplatin blood levels obtained from polymeric films application were low during the first 24 hours after the application; then, the cisplatin blood level increased gradually and progressively until it reached significantly higher plasmatic concentrations after 120 hours compared to intrapleural cisplatin solution (P=0.004) and intravenous administration (P=0.001), respectively. Considering cisplatin concentration at 168 hours after the application, animals treated with polymeric films had higher plasmatic values than animals treated with intrapleural cisplatin solution and intravenous cisplatin (P=0.001). Despite the high cisplatin plasmatic concentrations, treatment related-toxicity towards kidneys and liver was comparatively lower compared to the intravenous and intrapleural cisplatin administration and closer to the control levels. Conclusions Polymeric films loaded with cisplatin allowed to reach significantly higher intrapleural and plasmatic cisplatin concentrations compared to intrapleural and intravenous cisplatin solution, providing at the same time, a significant reduction of treatment related toxicity.

Malignant pleural mesothelioma (MPM) continues to be a distressing tumor due to its aggressive biologic behavior and scanty prognosis. Several therapeutic approaches have been tested both in clinical and preclinical settings, being intrapleural chemotherapy one of the most promising. Some years ago, our interest focused on polymeric films loaded with cisplatin for the adjuvant intrapleural treatment of surgical patients. After in vitro and in vivo studies in a rat recurrence model of MPM, the aim of this study was to evaluate the pharmacokinetics of the polymeric films in a sheep model in view of further studies in a clinical setting. An ovine model was used. Animals were divided into four groups according to pharmacologic treatment: control group (three animals undergoing left pneumonectomy and saline-NaCl solution); intrapleural hyaluronate cisplatin films (HYALCIS) group (six animals undergoing left pneumonectomy and intrapleural application of polymeric films loaded with cisplatin); intrapleural cisplatin solution (six animals undergoing left pneumonectomy and intrapleural application of cisplatin solution); intravenous cisplatin (five animals undergoing left pneumonectomy and intravenous administration of cisplatin solution). The primary objective was the plasmatic and pleural concentration of cisplatin in the treatment groups. The secondary objective was the treatment-related toxicity evaluated by plasmatic analysis performed at prearranged time intervals and histological examinations of tissue samples collected during animal autopsy. Analysis of variance (ANOVA) was used for statistical analysis. Bonferroni correction was applied for comparison between all groups. Twenty female Sardinian sheep with a mean weight of 45.1 kg were studied. All animals survived the surgical procedures. The whole surgical procedure had a mean duration of 113 minutes. Cisplatin blood levels obtained from polymeric films application were low during the first 24 hours after the application; then, the cisplatin blood level increased gradually and progressively until it reached significantly higher plasmatic concentrations after 120 hours compared to intrapleural cisplatin solution (P=0.004) and intravenous administration (P=0.001), respectively. Considering cisplatin concentration at 168 hours after the application, animals treated with polymeric films had higher plasmatic values than animals treated with intrapleural cisplatin solution and intravenous cisplatin (P=0.001). Despite the high cisplatin plasmatic concentrations, treatment related-toxicity towards kidneys and liver was comparatively lower compared to the intravenous and intrapleural cisplatin administration and closer to the control levels. Polymeric films loaded with cisplatin allowed to reach significantly higher intrapleural and plasmatic cisplatin concentrations compared to intrapleural and intravenous cisplatin solution, providing at the same time, a significant reduction of treatment related toxicity.

Data on specific abdominal surgery and Cushing's syndrome are infrequent and are usually included in the adrenalectomy reports. Current literature suggests the feasibility and reproducibility of the surgical adrenalectomies for patients diagnosed with non-functioning tumours and functioning adrenal tumours including pheochromocytoma, Conn's syndrome and Cushing's syndrome. Medical treatment for Cushing's syndrome is feasible but follow-up or clinical situations force the patient to undergo a surgical procedure. Laparoscopic surgery has become a gold standard nowadays in a broad spectrum of pathologies. Laparoscopic adrenalectomies are also standard procedures nowadays. However, despite the different characteristics and clinical disorders related to the laparoscopically removed adrenal tumours, the intraoperative and postoperative outcomes do not significantly differ in most cases between the different groups of patients, techniques and types of tumours. Tumour size, hormonal type and surgeon's experience could be different factors that predict intraoperative and postoperative complications. Transabdominal and retroperitoneal approaches can be considered. Outcomes for Cushing's syndrome do not differ depending on the surgical approach. Novel technologies and approaches such as single-port surgery or robotic surgery have proven to be safe and feasible. Laparoscopic adrenalectomy is a safe and feasible approach to adrenal pathology, providing the patients with all the benefits of minimally invasive surgery. Single-port access and robotic surgery can be performed but more data are required to identify their correct role between the different surgical approaches. Factors such as surgeon's experience, tumour size and optimal technique can affect the outcomes of this surgery.

This study aims to critically evaluate orthodontically induced external apical root resorption (OIEARR) in incisors of patients undergoing non-surgical orthodontic treatment of class II division 1 malocclusion by a systematic review of the published data. An electronic search of two databases was performed; the bibliographies of relevant articles were also reviewed. Studies were included if they examined the amount of OIEARR in incisors produced during non-surgical orthodontic treatment of individuals with class II division I malocclusion in the permanent dentition. Individuals had no previous history of OIEARR, syndromes, pathologies, or general diseases. Study selections, risk of bias assessment, and data extraction were performed in duplicate. Eight studies of moderate methodological quality were finally included. An increased prevalence (65.6% to 98.1%) and mild to moderate severity of OIEARR (<4 mm and <1/3 original root) were reported. No sex difference in root resorption was found. For the maxillary incisors, there was no evidence that either the central or lateral incisor was more susceptible to OIEARR. A weak to moderate positive correlation between treatment duration and root resorption, and anteroposterior apical displacement and root resorption was found. Current limited evidence suggests that non-surgical comprehensive orthodontic treatment to correct class II division 1 malocclusions causes increased prevalence and severity of OIEARR the more the incisor roots are displaced and the longer this movement takes.

In people with haemophilia or other congenital bleeding disorders undergoing surgical interventions, haemostatic treatment is needed in order to correct the underlying coagulation abnormalities and minimise the bleeding risk. This treatment varies according to the specific haemostatic defect, its severity and the type of surgical procedure. The aim of treatment is to ensure adequate haemostatic coverage for as long as the bleeding risk persists and until wound healing is complete. To assess the effectiveness and safety of different haemostatic regimens (type, dose and duration, modality of administration and target haemostatic levels) administered in people with haemophilia or other congenital bleeding disorders for preventing bleeding complications during and after surgical procedures. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Coagulopathies Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. We also searched the reference lists of relevant articles and reviews.Date of the last search: 20 November 2014. Randomised and quasi-randomised controlled trials comparing any hemostatic treatment regimen to no treatment or to another active regimen in children and adults with haemophilia or other congenital bleeding disorders undergoing any surgical intervention. Two authors independently assessed trials (eligibility and risks of bias) and extracted data. Meta-analyses were performed on available and relevant data. Of the 16 identified trials, four (112 participants) were eligible for inclusion.Two trials evaluated 59 people with haemophilia A and B undergoing 63 dental extractions. Trials compared the use of a different type (tranexamic acid or epsilon-aminocaproic acid) and regimen of antifibrinolytic agents as haemostatic support to the initial replacement treatment. Neither trial specifically addressed mortality (one of this review's primary outcomes); however, in the frame of safety assessments, no fatal adverse events were reported. The second primary outcome of blood loss was assessed after surgery and these trials showed the reduction of blood loss and requirement of post-operative replacement treatment in people receiving antifibrinolytic agents compared with placebo. The remaining primary outcome of need for re-intervention was not reported by either trial.Two trials reported on 53 people with haemophilia A and B with inhibitors treated with different regimens of recombinant activated factor VII (rFVIIa) for haemostatic coverage of 33 major and 20 minor surgical interventions. Neither of the included trials specifically addressed any of the review's primary outcomes (mortality, blood loss and need for re-intervention). In one trial a high-dose rFVIIa regimen (90 μg/kg) was compared with a low-dose regimen (35 μg/kg); the higher dose showed increased haemostatic efficacy, in particular in major surgery, with shorter duration of treatment, similar total dose of rFVIIa administered and similar safety levels. In the second trial, bolus infusion and continuous infusion of rFVIIa were compared, showing similar haemostatic efficacy, duration of treatment and safety. There is insufficient evidence from randomised controlled trials to assess the most effective and safe haemostatic treatment to prevent bleeding in people with haemophilia or other congenital bleeding disorders undergoing surgical procedures. Ideally large, adequately powered, and well-designed randomised controlled trials would be needed, in particular to address the cost-effectiveness of such demanding treatments in the light of the increasing present economic constraints, and to explore the new challenge of ageing patients with haemophilia or other congenital bleeding disorders. However, performing such trials is always a complex task in this setting and presently does not appear to be a clinical and research priority. Indeed, major and minor surgeries are effectively and safely performed in these individuals in clinical practice, with the numerous national and international recommendations and guidelines providing regimens for treatment in this setting mainly based on data from observational, uncontrolled studies.

To evaluate the impact of hypothermia on mortality in patients presenting with ruptured abdominal aortic aneurysms (rAAA). Between July 2007 and September 2009, 73 patients with ruptured AAAs presented to our Emergency Department (ED). Thirteen patients did not receive surgical treatment; of the 60 patients (46 men; mean age 76 years, range 63-90) who did, 35 had endovascular aneurysm repair (EVAR) and 25 open repair. Body temperatures, which were recorded upon arrival to the ED and operating room, during the procedure, and just prior to leaving the operating room, were analyzed for any association with mortality or hypotension. The primary outcome measure was the 30-day mortality rate. Six (17%) patients in the EVAR group and 10 (40%) patients in the open group died during the 30-day period. Temperature upon arrival to OR, lowest temperature recorded during the procedure, and temperature at the end of the procedure were higher among survivors (p<0.005), independent of the repair technique implemented. Patients in the EVAR group left the OR with a mean temperature of 35.5 degrees C versus 35.0 degrees C for patients in the open group (p = 0.12). Hypothermia is associated with increased mortality after repair of rAAA. Efforts to correct hypothermia are more frequently successful in patients undergoing EVAR. Increased communication with anesthesia providers, as well as aggressive measures to correct hypothermia, including active intravascular rewarming methods, should be considered to improve mortality in this gravely ill patient population.

In contrast to the significant advantages of laparoscopic versus open gastrectomy, robotic gastrectomy has shown little benefit over laparoscopic gastrectomy. This study aimed to compare multi-dimensional aspects of surgical outcomes after open, laparoscopic, and robotic gastrectomy. Data from 915 gastric cancer patients who underwent gastrectomy by one surgeon between March 2009 and May 2015 were retrospectively reviewed. Perioperative parameters were analyzed for short-term outcomes. Surgical success was defined as the absence of conversion to open surgery, major complications, readmission, positive resection margin, or fewer than 16 retrieved lymph nodes. This study investigated 241 patients undergoing open gastrectomy, 511 patients undergoing laparoscopic gastrectomy, and 173 patients undergoing robotic gastrectomy. For each approach, the respective incidences were as follows: conversion to open surgery (not applicable, 0.4%, and 0%; p = 0.444), in-hospital major complications (5.8, 2.7, and 1.2%; p = 0.020), delayed complications requiring readmission (2.9, 2.0, and 1.2%; p = 0.453), positive resection margin (1.7, 0, and 0%; p = 0.003), and inadequate number of retrieved lymph nodes (0.4, 4.1, and 1.7%; p = 0.010). Compared with open and laparoscopic surgery, robotic gastrectomy had the highest surgical success rate (90, 90.8, and 96.0%). Learning-curve analysis of success using cumulative sum plots showed success with the robotic approach from the start. Multivariate analyses identified age, sex, and gastrectomy extent as significant independent parameters affecting surgical success. Surgical approach was not a contributing factor. Open, laparoscopic, and robotic gastrectomy exhibited different incidences and causes of surgical failure. Robotic gastrectomy produced the best surgical outcomes, although the approach method itself was not an independent factor for success.

Prophylactic antibiotics to prevent surgical site infection after breast cancer surgery.

Surgery has been used as part of breast cancer treatment for centuries; however any surgical procedure has the potential risk of infection. Infection rates for surgical treatment of breast cancer are documented at between 3% and 15%, higher than average for a clean surgical procedure. Pre- and perioperative antibiotics have been found to be useful in lowering infection rates in other surgical groups, yet there is no consensus on the use of prophylactic antibiotics for breast cancer surgery. To determine the effects of prophylactic (pre- or perioperative) antibiotics on the incidence of surgical site infection (SSI) after breast cancer surgery. For this third update we searched the Cochrane Wounds Group Specialised Register (5 December 2013); the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); the Database of Abstracts of Reviews of Effects (DARE) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE; and EBSCO CINAHL. We applied no language or date restrictions. Randomised controlled trials of pre- and perioperative antibiotics for patients undergoing surgery for breast cancer were included. Primary outcomes were rates of surgical site infection (SSI) and adverse reactions. Two review authors independently examined the title and abstracts of all studies identified by the search strategy, then assessed study quality and extracted data from those that met the inclusion criteria. A total of eleven studies (2867 participants) were included in the review. Ten studies evaluated preoperative antibiotic compared with no antibiotic or placebo. One study evaluated perioperative antibiotic compared with no antibiotic. Pooling of the results demonstrated that prophylactic antibiotics administered preoperatively significantly reduce the incidence of SSI for patients undergoing breast cancer surgery without reconstruction (pooled risk ratio (RR) 0.67, 95% confidence interval (CI) 0.53 to 0.85). Analysis of the single study comparing perioperative antibiotic with no antibiotic found no statistically significant effect of antibiotics on the incidence of SSI (RR 0.11, 95% CI 0.01 to 1.95). No studies presented separate data for patients who underwent reconstructive surgery at the time of removal of the breast tumour. Prophylactic antibiotics administered preoperatively reduce the risk of SSI in patients undergoing surgery for breast cancer. Further studies involving patients undergoing immediate breast reconstruction are needed as studies have identified this group as being at higher risk of infection than those who do not undergo immediate breast reconstruction.

The purpose of the study was to analyze the healing of the deep and superficial lower first and second molars periodontium, after the surgical extraction of the contiguous impacted third molar, comparing 3 mucoperiosteal flap designs. 150 patients which had to undergo a impacted lower third molar surgery were enrolled in this study. They were checked from day 0 to day 90, in order to focus on the recovery quality of the soft tissues around the lower second molar, comparing 3 different flap designs. No intraoperatory incident happened. The complete recovery of the periodontium around the second molar has been shown in each patient after 90 days from surgery and each adverse reaction happened within the sixth week after surgery. Only 2 slight gengival recessions 0,5 mm have been find out. The impacted third molar surgery is an operation that, if rightly programmed and performed, is relatively safe. Besides, the correct handling and management of periodontium around the second molar and the choice of the flap type to be used support a correct recovery on the second molar periodontium, avoiding any long-term damage. This study wanted to analyze the healing of the deep and superficial lower second molar periodontium, after the impacted lower third molar surgery. In order to improve the surgical technique used for lower third molar germectomies, we wanted to compare 3 different kind of flap designs.

To determine whether the combination of transesophageal echocardiography (TEE) and contrast echocardiography (CE) accurately diagnose suspected cardiac masses using large sample data. Patients with cardiac masses undergoing surgical treatment were enrolled in this study. Routine transthoracic echocardiography (TTE) and TEE examinations were carried out, and CE examinations were carried out when needed. All patients' clinical data and imaging features were retrospectively reviewed. Surgery and histopathology served as the gold standard for diagnosing cardiac masses. A total of 252 consecutive patients were included in this study. Sixteen patients were lost to follow-up and were excluded from the study. The combinations of TEE and CE yielded the correct pathologic diagnosis in 225 of 230 patients (97.8%), while CT yielded the correct pathologic diagnosis in 122 of 141 patients (86.5%), p<0.01. TEE yielded the correct pathologic diagnosis in 219 of 226 patients (96.9%), and CE yielded the correct pathologic diagnosis in 45 of 48 patients (93.8%). TTE alone yielded the correct pathologic diagnosis in 163 of 236 patients (69.1%), p<0.001 for all. TEE imaging provided detailed and precise information regarding cardiovascular morphology, anatomy, hemodynamics and function, and CE provided information regarding tissue characteristics without subjecting patients to radiation exposure. The combination of TEE and CE is feasible for the detection of suspected cardiac masses, especially in diagnosing and differentiating between benign and malignant lesions.

This study reviewed the literature regarding the pros and cons of various surgical approaches (anterior, anterolateral, combined, and posterior) for correction of post-tubercular kyphosis. The anterior and anterolateral approaches are effective in improving neurological deficit but not in correcting kyphosis. The combined anterior and posterior approach and the posterior approach combined with 3-column osteotomy achieve good neurological improvement and kyphosis correction. The latter is superior when expertise and facilities are available.

To assess unenhanced magnetic resonance imaging (MRI) in the preoperative evaluation of obstructive epiphora in patients undergoing dacryocystorhinostomy (DCR) and in particular, to evaluate the efficacy of this technique in the detection of the exact level of obstruction occurring in the naso-lachrymal duct (NLD). The correct identification and characterization of the NLD and its obstructions lead to a more effective surgery, preventing recurrent dacryocystitis after the surgical treatment. From January 2009 to December 2014, 127 obstructive epiphoras were diagnosed and treated in 127 patients (35 M, 92 F; mean age 60.7 ± 7.48 years, range 42-75 years) with endoscopic DCR, in a IRB-approved protocol. To precisely define the morphology of the NLD and the site of obstruction, some of these patients (67/127) underwent unenhanced 1.5-T MR with TrueFISP and VIBE sequences, while the remaining (60/127) underwent Gadolinium-enhanced 1.5-T MR. Afterwards, surgery checked the real site of obstruction in both groups of patients (enhanced and unenhanced MR), with surgical outcomes matched with previous MR reports. In all cases, unenhanced MRI was able to detect the exact site of obstruction along the NLD, allowing a correct planning of surgical endoscopic procedures. On the contrary, enhanced MRI wrongly diagnosed six patients with proximal stenosis (6/60, 10.0%) as intermediate NLD obstruction. Unenhanced MRI was found to be more accurate than enhanced MRI with a statistical significant difference (p value = 0.0256) and obviously cheaper and easier to perform. All imaging reports were verified with surgery. The correct identification of the level of obstruction allowed successful surgery in around 73% (93/127) of patients, who had no recurrence during 6-month follow-up. In patients with epiphora, unenhanced MR showed to be highly reliable and even more effective than enhanced MR in the preoperative characterization of NLD stenosis, with no need of performing complex, time-wasting and expensive procedures for the administration of topical contrast media.

A retrospective study. To analyze the efficacy and safety of perioperative halo-gravity traction as an adjunct to posterior vertebral column resection (PVCR) in the treatment of patients with severe congenital scoliosis and coexisting asymptomatic intraspinal pathologies (diastematomyelia and/or tethered cord). Few reports to our knowledge review the use of perioperative halo-gravity traction and PVCR in this patient population. A total of 17 patients with a minimum 2-year follow-up who underwent PVCR using perioperative halo-gravity traction were analyzed. Patients were analyzed by age at date of examination (range, 11-23 y; mean, 14.4 y), sex (7 male, 10 female), major coronal curve magnitude (range, 108-149 degrees; average, 125 degrees), major sagittal curve magnitude (range, 72-118 degrees; average, 91 degrees). Complications related to halo traction and PVCR were reviewed. Radiographic outcomes demonstrated Cobb angle of major curve had an average correction of 28% after halo traction and it measured 53 degrees (range, 42-84 degrees) at the last follow-up, for a 58% correction. Maximal kyphosis improved to 58 degrees (range, 43-76 degrees) at ultimate follow-up. There were no permanent neurological deficits in this series. The study results suggested that surgical treatment for intraspinal abnormality may be unnecessary in asymptomatic patients with severe congenital scoliosis who are undergoing scoliosis corrective surgery. PVCR combined with perioperative traction is a safe and effective alternative for such patients.

The objective of this study was to estimate the economic consequences of expanding options for early pregnancy loss (EPL) treatment beyond expectant management and operating room surgical evacuation (usual care). We constructed a decision model using a hypothetical cohort of women undergoing EPL management within a 30 day horizon. Treatment options under the usual care arm include expectant management and surgical uterine evacuation in an operating room (OR). Treatment options under the expanded care arm included all evidence-based safe and effective treatment options for EPL: expectant management, misoprostol treatment, surgical uterine evacuation in an office setting, and surgical uterine evacuation in an OR. Probabilities of entering various treatment pathways were based on previously published observational studies. The cost per case was US $241.29 lower for women undergoing treatment in the expanded care model as compared with the usual care model (US $1033.29 per case vs US $1274.58 per case, expanded care and usual care, respectively). The model was the most sensitive to the failure rate of the expectant management arm, the cost of the OR surgical procedure, the proportion of women undergoing an OR surgical procedure under usual care, and the additional cost per patient associated with implementing and using the expanded care model. This study demonstrates that expanding women's treatment options for EPL beyond what is typically available can result in lower direct medical expenditures. Copyright © 2015 Elsevier Inc.

Patients with anophthalmic or phthisis socket suffer from cosmetic problems. To resolve those problems, the authors present the surgical outcomes of deep superior sulcus (DSS) augmentation using acellular dermal matrix in patients with anophthalmic or phthisis socket. The authors retrospectively reviewed anophthalmic or phthisis patients who underwent surgery for DSS augmentation using acellular dermal matrix. To evaluate surgical outcomes, the authors focused on 3 aspects: the possibility of wearing contact prosthesis, the degree of correction of the DSS, and any surgical complications. The degree of correction of DSS was classified as excellent: restoration of superior sulcus enough to remove sunken sulcus shadow; fair: gain of correction effect but sunken shadow remained; or fail: no effect of correction at all. Ten eyes of 10 patients were included. There was a mean 21.3 ± 37.1-month period from evisceration or enucleation to the operation for DSS augmentation. All patients could wear contact prosthesis after the operation (100%). The degree of correction was excellent in 8 patients (80%) and fair in 2. Three of 10 (30%) showed complications: eyelid entropion, upper eyelid multiple creases, and spontaneous wound dehiscence followed by inflammation after stitch removal. Uneven skin surface and paresthesia in the forehead area of the affected eye may be observed after surgery. The overall surgical outcomes were favorable, showing an excellent degree of correction of DSS and low surgical complication rates. This procedure is effective for patients who have DSS in the absence or atrophy of the eyeball.

A perspective on the use of an enhanced recovery program in open, non-instrumented day surgery for degenerative lumbar and cervical spinal conditions.

A means of significantly shortening patients' length of hospital stay, improving their outcome and thereby also reducing costs is to use an enhanced recovery program (ERP) which is increasingly being used in a number of surgical sub-specialties. This paper provides a perspective on its prospective use in a wide-ranging, unselected cohort of patients undergoing open spinal surgery for degenerative lumbar and cervical spinal conditions. Selected spinal cases undergoing day surgery have been increasingly reported. A prospective, unselected, consecutive cohort of 246 cases, over an 18-month period, undergoing open, non-instrumented decompression spinal surgery and using ERP (and the concept of "bundles of care") was analyzed. Nine cases could not be included as they did not fully meet the entry criteria. No routine follow-up was arranged for the study group. The ages ranged widely, from 23-90 years (mean 57). In 187 the surgery for degenerative conditions was lumbar and in 50 cervical. The ASA (American Association of Anesthesiologists) ratings were 108=1; 107=2 and 22=3. Using the United Kingdom (UK) National Health Service (NHS) definitions of length of stay 225 (95%) could be finally classified as "ambulatory" and 12 (5%) were "short stay". A sub-cohort of 126 (53.2%) were "day cases". The follow-up was >1 year for all. There were no wound infections reported; 5 postdischarge cases (2.1%) needed to be seen in the Accident and Emergency (A&E) Department (less than 4 days postsurgery), but none needed re-admission; and there were 7 re-admissions (2.5%), between 4 and 30 days, and of these 6 required a further surgical procedure. There were no long-term instability complications reported in this cohort. ERP can be used for spinal surgery. There were identifiable and correctable medical and social factors found on analysis which could significantly increase the "day cases" number to over 90%.

Mild and moderate functional ischemic mitral insufficiency present at the time of surgical revascularization present clinical uncertainty. It is unclear whether the relatively poor outcomes in this cohort are dependent on valvular function or related to left ventricular dysfunction. The purpose of this study was to examine the early and late outcomes in patients with less-than-severe functional ischemic mitral insufficiency at the time of isolated coronary artery bypass grafting (CABG). From 1996 through 2004, 2242 consecutive patients undergoing isolated CABG were identified as having none to moderate mitral regurgitation (MR) and no valve leaflet pathology. All of the patients at this single institution routinely had an intraoperative transesophageal echocardiography, prospectively quantified MR, and ejection fraction (EF). The New York State Cardiac Surgery Reporting System infrastructure was used to prospectively collect in-hospital patient variables and outcomes. Social Security Death Benefit Index was used to determine long-term survival. Odds ratio and significance (P value) are presented for each determined risk factor. There were 841 patients (37.5%) with no MR, 1137 (50.7%) with mild MR, and 264 (11.8%) with moderate MR. The patients with moderate MR were more likely to be older, female, and have more renal disease, previous MI, congestive heart failure, previous cardiac surgery, and lower EFs. Hospital mortality was independently and significantly associated with renal disease, decreasing EF, increasing age, previous cardiac operation, and cerebral vascular disease. Multivariable analysis revealed decreased survival with increasing age, previous operation, congestive heart failure, diabetes, nonelective operation, decreasing EF, and the presence of moderate MR (expbeta = 1.49; P=0.007) and mild MR (expbeta = 1.34; P=0.033). Independent of ventricular function, mild and moderate functional mitral insufficiency are associated with significantly decreased survival in patients undergoing CABG. Whether correction of moderate functional MR at the time of CABG improves outcome still needs to be determined.

To compare differences in visual acuity, contrast sensitivity, complications, and higher-order ocular aberrations (HOAs) in eyes with stable myopia undergoing either photo-refractive keratectomy (PRK) or thin-flap laser in situ keratomileusis (LASIK) (intended flap thickness of 90 μm) using the VISX Star S4 CustomVue excimer laser and the IntraLase FS60 femtosecond laser at 1, 3, and 6 months postoperatively. In this prospective, masked, and randomized pilot study, refractive surgery was performed contralaterally on 52 eyes: 26 with PRK and 26 with thin-flap LASIK. Primary outcome measures were uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), contrast sensitivity, and complications. At 6 months, mean values for UDVA (logMAR) were -0.043 ± 0.668 and -0.061 ± 0.099 in the PRK and thin-flap LASIK groups, respectively (n = 25, P = 0.466). UDVA of 20/20 or better was achieved in 96% of eyes undergoing PRK and 92% of eyes undergoing thin-flap LASIK, whereas 20/15 vision or better was achieved in 73% of eyes undergoing PRK and 72% of eyes undergoing thin-flap LASIK (P > 0.600). Significant differences were not found between treatment groups in contrast sensitivity (P ≥ 0.156) or CDVA (P = 0.800) at postoperative 6 months. Types of complications differed between groups, notably 35% of eyes in the thin-flap LASIK group experiencing complications, including microstriae and 2 flap tears. Under well-controlled surgical conditions, PRK and thin-flap LASIK refractive surgeries achieve similar results in visual acuity, contrast sensitivity, and induction of HOAs, with differences in experienced complications.

The decision to administer blood products is complex and multifactorial. Accurate assessment of the concentration of hemoglobin [Hgb] is a key component of this evaluation. Recently a noninvasive method of continuously measuring hemoglobin (SpHb) has become available with multi-wavelength Pulse CO-Oximetry. The accuracy of this device is well documented, but the trending ability of this monitor has not been previously described. Twenty patients undergoing major thoracic and lumbar spine surgery were recruited. All patients received radial arterial lines. On the contralateral index finger, a R1 25 sensor (Rev E) was applied and connected to a Radical-7 Pulse CO-Oximeter (both Masimo Corp, Irvine, CA). Blood samples were drawn intermittently at the anesthesia provider's discretion and were analyzed by the operating room satellite laboratory CO-Oximeter. The value of Hgb and SpHb at that time point was compared. Trend analysis was performed by the four quadrant plot technique, testing directionality of change, and Critchley's polar plot method testing both directionality and magnitude of the change in values. Eighty-eight samples recorded at times of sufficient signal quality were available for analysis. Four quadrant plot analysis revealed 94% of data within the quadrants associated with the correct direction change, and 90% of data points lay within the analysis bounds proposed by Critchley. Pulse CO-Oximetry offers an acceptable trend monitor in patients undergoing major spine surgery. Future work should explore the ability of this device to detect large changes in hemoglobin, as well as its applicability in additional surgical and non-surgical patient populations.

Patients who undergo prolonged surgical procedures are at risk of developing pressure ulcers. Recent systematic reviews suggest that pressure redistribution overlays on operating tables significantly decrease the associated risk. Little is known about the cost effectiveness of using these overlays in a prevention program for surgical patients. Using a Markov cohort model, we evaluated the cost effectiveness of an intraoperative prevention strategy with operating table overlays made of dry, viscoelastic polymer from the perspective of a health care payer over a 1-year period. We simulated patients undergoing scheduled surgical procedures lasting ≥90 min in the supine or lithotomy position. Compared with the current practice of using standard mattresses on operating tables, the intraoperative prevention strategy decreased the estimated intraoperative incidence of pressure ulcers by 0.51%, corresponding to a number-needed-to-treat of 196 patients. The average cost of using the operating table overlay was $1.66 per patient. Compared with current practice, this intraoperative prevention strategy would increase slightly the quality-adjusted life days of patients and by decreasing the incidence of pressure ulcers, this strategy would decrease both hospital and home care costs for treating fewer pressure ulcers originated intraoperatively. The cost savings was $46 per patient, which ranged from $13 to $116 by different surgical populations. Intraoperative prevention was 99% likely to be more cost effective than the current practice. In patients who undergo scheduled surgical procedures lasting ≥90 min, this intraoperative prevention strategy could improve patients' health and save hospital costs. The clinical and economic evidence support the implementation of this prevention strategy in settings where it has yet to become current practice. Copyright © 2011 Mosby, Inc. All rights reserved.

Functional endoscopic sinus surgery (FESS) was historically predicated on targeted widening of narrow anatomic structures that caused postobstructive persistent sinus inflammation. It is now clear that chronic rhinosinusitis (CRS) is a multifactorial disease with subsets of patients which may require a more extensive surgical approach. This study compares quality-of-life (QOL) and disease severity outcomes after FESS based on the extent of surgical intervention. Participants with CRS were prospectively enrolled into an ongoing, multi-institutional, observational, cohort study. Surgical extent was determined by physician discretion. Participants undergoing bilateral frontal sinusotomy, ethmoidectomy, maxillary antrostomy, and sphenoidotomy were considered to have undergone "complete" surgery, whereas all other participants were categorized as receiving "targeted" surgery. Improvement was evaluated between surgical subgroups with at least 6-month follow-up using the 22-item Sino-Nasal Outcome Test (SNOT-22) and the Brief Smell Inventory Test (B-SIT). A total of 311 participants met inclusion criteria with 147 subjects undergoing complete surgery and 164 targeted surgery. A higher prevalence of asthma, acetylsalicylic acid (ASA) sensitivity, nasal polyposis, and a history of prior sinus surgery (p ≤ 0.002) was present in participants undergoing complete surgery. Mean improvement in SNOT-22 (28.1 ± 21.9 vs 21.9 ± 20.6; p = 0.011) and B-SIT (0.8 ± 3.1 vs 0.2 ± 2.4; p = 0.005) was greater in subjects undergoing complete surgery. Regression models demonstrated a 5.9 ± 2.5 greater relative mean improvement on SNOT-22 total scores with complete surgery over targeted approaches (p = 0.016). Complete surgery was an independent predictor of greater postoperative SNOT-22 score improvement, yet did not achieve clinical significance. Further study is needed to determine the optimal surgical extent. © 2015 ARS-AAOA, LLC.

Approximately 30% of patients undergoing elective general surgery smoke cigarettes. The association between smoking status and hospital costs in general surgery patients is unknown. The objectives of this study were to compare total inpatient costs in current smokers, former smokers, and never smokers undergoing general surgical procedures in Veterans Affairs (VA) hospitals; and to determine whether the relationship between smoking and cost is mediated by postoperative complications. Patients undergoing general surgery during the period of October 1, 2005 to September 30, 2006 were identified in the VA Surgical Quality Improvement Program (VASQIP) data set. Inpatient costs were extracted from the VA Decision Support System (DSS). Relative surgical costs (incurred during index hospitalization and within 30 days of operation) for current and former smokers relative to never smokers, and possible mediators of the association between smoking status and cost were estimated using generalized linear regression models. Models were adjusted for preoperative and operative variables, accounting for clustering of costs at the hospital level. Of the 14,853 general surgical patients, 34% were current smokers, 39% were former smokers, and 27% were never smokers. After controlling for patient covariates, current smokers had significantly higher costs compared with never smokers: relative cost was 1.04 (95% Cl 1.00 to 1.07; p = 0.04); relative costs for former smokers did not differ significantly from those of never smokers: 1.02 (95% Cl 0.99 to 1.06; p = 0.14). The relationship between smoking and hospital costs for current smokers was partially mediated by postoperative respiratory complications. These findings complement emerging evidence recommending effective smoking cessation programs in general surgical patients and provide an estimate of the potential savings that could be accrued during the preoperative period.

SUMMARY OBJECTIVES Temporal lobe epilepsy (TLE) patients experience significant deficits in category-related object recognition and naming following standard surgical approaches. These deficits may result from a decoupling of core processing modules (e.g., language, visual processing, semantic memory), due to “collateral damage” to temporal regions outside the hippocampus following open surgical approaches. We predicted stereotactic laser amygdalohippocampotomy (SLAH) would minimize such deficits because it preserves white matter pathways and neocortical regions critical for these cognitive processes. METHODS Tests of naming and recognition of common nouns (Boston Naming Test) and famous persons were compared with nonparametric analyses using exact tests between a group of nineteen patients with medically-intractable mesial TLE undergoing SLAH (10 dominant, 9 nondominant), and a comparable series of TLE patients undergoing standard surgical approaches (n=39) using a prospective, non-randomized, non-blinded, parallel group design. RESULTS Performance declines were significantly greater for the dominant TLE patients undergoing open resection versus SLAH for naming famous faces and common nouns (F=24.3, p<.0001, η2=.57, & F=11.2, p<.001, η2=.39, respectively), and for the nondominant TLE patients undergoing open resection versus SLAH for recognizing famous faces (F=3.9, p<.02, η2=.19). When examined on an individual subject basis, no SLAH patients experienced any performance declines on these measures. In contrast, 32 of the 39 undergoing standard surgical approaches declined on one or more measures for both object types (p<.001, Fisher’s exact test). Twenty-one of 22 left (dominant) TLE patients declined on one or both naming tasks after open resection, while 11 of 17 right (non-dominant) TLE patients declined on face recognition. SIGNIFICANCE Preliminary results suggest 1) naming and recognition functions can be spared in TLE patients undergoing SLAH, and 2) the hippocampus does not appear to be an essential component of neural networks underlying name retrieval or recognition of common objects or famous faces.

Drug-resistant temporal lobe epilepsy (TLE) often requires thorough investigation to define the epileptogenic zone for surgical treatment. We used simultaneous interictal scalp EEG-fMRI to evaluate its value for predicting long-term postsurgical outcome. 30 patients undergoing presurgical evaluation and proceeding to temporal lobe (TL) resection were studied. Interictal epileptiform discharges (IEDs) were identified on intra-MRI EEG and used to build a model of haemodynamic changes. In addition, topographic electroencephalographic correlation maps were calculated between the average IED during video-EEG and intra-MRI EEG, and used as a condition. This allowed the analysis of all data irrespective of the presence of IED on intra-MRI EEG. Mean follow-up after surgery was 46 months. International League Against Epilepsy (ILAE) outcomes 1 and 2 were considered good, and 3-6 poor, surgical outcome. Haemodynamic maps were classified according to the presence (Concordant) or absence (Discordant) of Blood Oxygen Level-Dependent (BOLD) change in the TL overlapping with the surgical resection. The proportion of patients with good surgical outcome was significantly higher (13/16; 81%) in the Concordant than in the Discordant group (3/14; 21%) (χ(2) test, Yates correction, p=0.003) and multivariate analysis showed that Concordant BOLD maps were independently related to good surgical outcome (p=0.007). Sensitivity and specificity of EEG-fMRI results to identify patients with good surgical outcome were 81% and 79%, respectively, and positive and negative predictive values were 81% and 79%, respectively. The presence of significant BOLD changes in the area of resection on interictal EEG-fMRI in patients with TLE retrospectively confirmed the epileptogenic zone. Surgical resection including regions of haemodynamic changes in the TL may lead to better postoperative outcome. Published by the BMJ Publishing Group Limited.

The usefulness of preoperative oral antibiotics for the prevention of surgical site infection in elective colorectal surgery remains controversial. This study aimed to investigate the effects of oral antimicrobial prophylaxis in addition to intravenous antimicrobial prophylaxis on patients with ulcerative colitis undergoing restorative proctocolectomy. This study was a randomized, nonblinded, single-center clinical trial. This study was conducted between July 1, 2006, and April 30, 2009, at Hyogo College of Medicine. Two hundred patients with ulcerative colitis scheduled to undergo restorative proctocolectomy with IPAA with an open approach were randomly assigned to either group A or B (n = 100). Combined use of preoperative oral antibiotics and intravenous antimicrobial prophylaxis were given to group A, and intravenous antimicrobial prophylaxis alone was given to group B. Patients in group A received oral antibiotics the day before surgery (500 mg of kanamycin and 500 mg of metronidazole at 2:00 P.M., 3:00 P.M., and 9:00 P.M.), whereas those in group B did not. All patients underwent preoperative mechanical bowel preparation, and intravenous antimicrobial prophylaxis with second-generation cephalosporin was given for 24 hours. The primary end point of this study was the incidence of overall surgical site infection according to intention-to-treat analysis. The incidence of overall surgical site infection was significantly lower in group A (6/97 patients, 6.1%) than in group B (22/98 patients, 22.4%) (p = 0.0024). In multivariate analysis, the administration of oral antibiotics (OR, 0.178; 95% CI, 0.057-0.552; p = 0.003) and ASA score ≥3 (OR, 5.343; 95% CI, 1.595-17.891; p = 0.007) were independent risk factors for surgical site infection. This study is limited because of its open-label nature. Combined oral and intravenous antimicrobial prophylaxis in patients with ulcerative colitis undergoing restorative proctocolectomy with IPAA contributed to the prevention of surgical site infection.

Airway injury is a potentially serious and costly adverse event of anesthesia care. The epidemiologic characteristics of airway injury have not been well documented. The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) is a multicenter, prospective, outcome-oriented database for patients undergoing major surgical procedures. Using the NSQIP data for the years 2005 to 2008, we examined the incidence of, and risk factors for, airway injury. Of the 563,190 patients studied, 1202 (0.2%) sustained airway injury. The most common airway injury was lip laceration/hematoma (61.4%), followed by tooth injury (26.1%), tongue laceration (5.7%), pharyngeal laceration (4.7%), and laryngeal laceration (2.1%). Multivariable logistic modeling revealed an increased risk of airway injury in patients with Mallampati class III (adjusted odds ratio [OR], 1.69; 99% confidence interval [CI], 1.36-2.11, relative to patients with Mallampati classes I and II) or class IV (adjusted OR, 2.6; 99% CI, 1.52-4.02), and in patients aged 80 years or older (adjusted OR, 1.50; 99% CI, 1.02-2.19, relative to patients aged 40 to 49 years). The risk of airway injury for patients undergoing major surgical procedures is approximately 1 in 500. Patients with difficult airways as indicated by Mallampati classes III and IV are at significantly increased risk of sustaining airway injury during anesthesia for major surgical procedures.

[Hereditary heterozygous factor VII deficiency in patients undergoing surgery : Clinical relevance].

A hereditary deficiency in coagulation factor VII (FVII) may affect the international normalized ratio (INR) value. However, FVII deficiency is occasionally associated with a tendency to bleed spontaneously. We hypothesized that perioperative substitution with coagulation factor concentrates might not be indicated in most patients. In this retrospective data analysis, we included all patients with hereditary heterozygous FVII deficiency who underwent surgical procedures at the University Hospital Basel between December 2010 and November 2015. In addition, by searching the literature, we identified publications reporting patients with FVII deficiency undergoing surgical procedures without perioperative substitution. We identified 22 patients undergoing 46 surgical procedures, resulting in a prevalence of 1:1500-2000. Coagulation factor concentrates were administered during the perioperative period in 15 procedures (33 %), whereas in the other 31 procedures (66 %), FVII deficiency was not substituted. No postoperative bleeding or thromboembolic events were reported. In addition, we found no differences in pre- and postoperative hemoglobin and coagulation parameters, with the exception of an improved postoperative INR value in the substituted group. In the literature review, we identified five publications, including 125 patients with FVII deficiency, undergoing 213 surgical procedures with no perioperative substitution. Preoperative substitution using coagulation factor concentrates does not seem to be mandatory in patients with an FVII level ≥15 %. For decision-making on preoperative substitution, patient history of an increased tendency to bleed may be more important than the FVII level or increased INR value.

To analyze pre-surgical predictive factors of post-surgical pain in patients undergoing hip or knee arthoplasty. A systematic literature review was performed. We defined a sensitive strategy on Medline, Embase and Cochrane Library up to May 2013. The inclusion criteria were: patients undertaking knee and/or hip arthroplasty, adults with moderate or severe pain (≥4 on a Visual Analog Scale) in whom predictive factors of post-surgical pain were evaluated before surgery. Systematic reviews, meta-analyses, controlled trials and observational studies were selected. We excluded animals and basic science articles, reviews of prosthesis, prosthesis due to fractures, patients with rheumatic diseases or studies with mixed population in which disaggregated data was not possible to obtain. A total 37 articles of moderate quality were selected. The articles included representative patients undergoing a knee or hip arthroplasty in our country; most of them were aged 60 years or above, with osteoarthritis, and with a high rate of obesity and comorbidities. We found great variability regarding the type of studies and predictive factors. There was a strong association between post-surgical pain and the following pre-surgical factors: female gender, low socio-economic status, higher pain, comorbidities, low back pain, poor functional status, and psychological factors (depression, anxiety or catastrophic pain). There are pre-surgical factors that might influence post-surgical pain in patients undergoing a knee or hip arthroplasty. Therefore, they should be taken into account when considering an arthroplasty. Copyright © 2014 Elsevier España, S.L.U. y Sociedad Española de Reumatología y Colegio Mexicano de Reumatología.

Both medical and surgical abortions are popular in developing countries. However, the monetary costs of these two methods have not been compared. 430 women seeking abortions were recruited in 2008. Either a medical or surgical method was used for the abortion. We adopted the perspective of a third-party payer. Cost-minimization analysis was used based on all charges for the overall procedures in an out-patient clinic in Guangzhou, China. 219 subjects (51%) chose a medical method (mifepristone and misoprostol), whereas 211 subjects (49%) chose a surgical method. The efficacy in the surgical group was significantly higher than in the medical group (100 vs. 90%, p < 0.001). Surgical abortion incurred much more costs than medical abortion on average after initial treatment. When the subsequent costs were accumulated within the 2-week follow-up, the mean total cost in the medical group increased significantly due to failure of abortion and persistent bleeding. Patients undergoing medical abortion eventually incurred equivalent expenses compared to patients undergoing surgical abortion (p = 0.42). There was no difference in the mean final costs between the two abortion methods. Complications of persistent bleeding and failure to abort (requiring surgical intervention) in the medical treatment group increased the final mean total cost substantially. Copyright © 2011 S.

Background and Aims: Endoscopic sinus surgery (ESS) provides a challenge and an opportunity to the anesthesiologists to prove their mettle and give the surgeons a surgical field which can make their delicate surgery safer,more precise and faster. The aim of the study was to evaluate the surgical field and the rate of blood loss in patients premedicated with oral clonidine versus oral diazepam for endoscopic sinus surgery. Material and Methods: ASA I or II patients who were scheduled to undergo ESS were randomly allocated to group D (n = 30) or group C (n = 30). The patients' vital parameters, propofol infusion rate, and rate of blood loss were observed and calculated. The surgeon, who was blinded, rated the visibility of the surgical field from grade 0-5. Results: In the clonidine group, the rate of blood loss, the surgical time, propofol infusion rate was found to be statistically lower as compared to the diazepam group. Also a higher number of patients in the clonidine group had a better surgical score (better surgical field) than the diazepam group and vice versa. Conclusions: Premedication with clonidine as compared to diazepam, provides a better surgical field with less blood loss in patients undergoing ESS. PMID:27275059

THD Doppler procedure for hemorrhoids: the surgical technique.

PubMed

Ratto, C

2014-03-01

Transanal hemorrhoidal dearterialization (THD) is an effective treatment for hemorrhoidal disease. The ligation of hemorrhoidal arteries (called "dearterialization") can provide a significant reduction of the arterial overflow to the hemorrhoidal piles. Plication of the redundant rectal mucosa/submucosa (called "mucopexy") can provide a repositioning of prolapsing tissue to the anatomical site. In this paper, the surgical technique and perioperative patient management are illustrated. Following adequate clinical assessment, patients undergo THD under general or spinal anesthesia, in either the lithotomy or the prone position. In all patients, distal Doppler-guided dearterialization is performed, providing the selective ligation of hemorrhoidal arteries identified by Doppler. In patients with hemorrhoidal/muco-hemorrhoidal prolapse, the mucopexy is performed with a continuous suture including the redundant and prolapsing mucosa and submucosa. The description of the surgical procedure is complemented by an accompanying video (see supplementary material). In long-term follow-up, there is resolution of symptoms in the vast majority of patients. The most common complication is transient tenesmus, which sometimes can result in rectal discomfort or pain. Rectal bleeding occurs in a very limited number of patients. Neither fecal incontinence nor chronic pain should occur. Anorectal physiology parameters should be unaltered, and anal sphincters should not be injured by following this procedure. When accurately performed and for the correct indications, THD is a safe procedure and one of the most effective treatments for hemorrhoidal disease.

Routine castration in 568 draught colts: incidence of evisceration and omental herniation.

Castration is one of the most common routine surgical procedures performed in the horse, from which a number of potential complications can arise. We undertook a prospective evaluation of short-term complications associated with castration of draught colts over a 3-year period (1998-2000). To compare castration complications in a large number of draught foals with previously published literature. Five hundred and sixty-eight draught colts, age 4 or 5 months, were castrated in field conditions. Foals were observed for complications for 24 h post operatively. There was no significant difference in complication rates between open and closed surgical techniques. Inguinal/scrotal hernia rate was 4.6% (26/568) prior to surgery, and evisceration of the small intestine occurred in 4.8% (27/568). Foals observed to eviscerate underwent immediate surgical correction with an overall survival rate of 72.2% (13/18). Omental herniation was seen in 2.8% (16/568) of colts. This study showed no difference between the closed and open techniques of castration and the rate of omental herniation or evisceration. The evisceration rate in combination with the omental and presurgical herniation rates approached 12.2%, which is high enough to warrant further examination. Future investigation should help to assess predisposing factors for evisceration. Regardless of the technique employed, herniation appears to pose a significant risk to draught foals undergoing castration.

The aim of the study was to evaluate the surgical management and the role of different prognostic factors on survival outcomes of women affected by genital (i.e., vulvar and vaginal) melanoma. Data of patients undergoing primary surgical treatment for genital melanoma were evaluated in this retrospective study. Baseline, pathological, and postoperative variables were tested to identify prognostic factors. Five-year disease-free survival (DFS) and overall survival (OS) were analyzed using Kaplan-Meier and Cox proportional hazards models. Overall, 98 patients met the inclusion criteria. Sixty-seven (68%) and 31 (32%) patients in this study population were diagnosed with vulvar and vaginal melanoma, respectively. Median (range) DFS and OS were 12 (1-70) and 22 (1-70) months, respectively. Considering factors influencing DFS, we observed that at multivariate analysis, only vaginal localization (hazard ratio [HR] = 3.72; 95% CI = 1.05-13.2) and number of mitoses (HR = 1.24; 95% CI = 1.11-1.39) proved to be associated with worse DFS. Nodal status was the only independent factor influencing 5-year OS in patients with vulvar (HR = 1.76; 95% CI = 1.22-2.54; p = .002) and vaginal (HR = 3.65; 95% CI = 1.08-12.3; p = .03) melanoma. Genital melanomas are characterized by a poor prognosis. Number of mitoses and lymph node status are the main factors influencing survival. Surgery is the mainstay of treatment. A correct and prompt diagnosis is paramount.

X-linked hypophosphatemia is an inheritable disorder of renal phosphate wasting that clinically manifests with rachitic bone pathology. X-linked hypophosphatemia is frequently misdiagnosed and mismanaged. Optimized medical therapy is the cornerstone of treatment. Even with ideal medical management, progressive bony deformity may develop in some children and adults. Medical treatment is paramount to the success of orthopaedic surgical procedures in both children and adults with X-linked hypophosphatemia. Successful correction of complex, multiapical bone deformities found in patients with X-linked hypophosphatemia is possible with careful surgical planning and exacting surgical technique. Multiple methods of deformity correction are used, including acute and gradual correction. Treatment of some pediatric bony deformity with guided growth techniques may be possible.

We implemented a hysterectomy-specific surgical site infection prevention bundle after a higher-than-expected surgical site infection rate was identified at our institution. We evaluate how this bundle affected the surgical site infection rate, length of hospital stay, and 30-day postoperative readmission rate. This is a quality improvement study featuring retrospective analysis of a prospectively implemented, multidisciplinary team-designed surgical site infection prevention bundle that consisted of chlorhexidine-impregnated preoperative wipes, standardized aseptic surgical preparation, standardized antibiotic dosing, perioperative normothermia, surgical dressing maintenance, and direct feedback to clinicians when the protocol was breached. There were 2,099 hysterectomies completed during the 33-month study period. There were 61 surgical site infections (4.51%) in the pre-full bundle implementation period and 14 (1.87%) in the post-full bundle implementation period; we found a sustained reduction in the proportion of patients experiencing surgical site infection during the last 8 months of the study period. After adjusting for clinical characteristics, patients who underwent surgery after full implementation were less likely to develop a surgical site infection (adjusted odds ratio [OR] 0.46, P=.01) than those undergoing surgery before full implementation. Multivariable regression analysis showed no statistically significant difference in postoperative days of hospital stay (adjusted mean ratio 0.95, P=.09) or rate of readmission for surgical site infection-specific indication (adjusted OR 2.65, P=.08) between the before and after full-bundle implementation periods. The multidisciplinary implementation of a gynecologic perioperative surgical site infection prevention bundle was associated with a significant reduction in surgical site infection rate in patients undergoing hysterectomy.

To evaluate the factors that influence the surgical margin state in patients undergoing cold knife conization at the University Clinic of Gynecology and Obstetrics in Skopje, Republic of Macedonia Materials and methods: We have retrospectively analyzed the medical records of all patients that underwent a cold knife conization at our Clinic in 2015. We cross-referenced the surgical margin state with the histopathological diagnosis (LSIL, HSIL or micro-invasive/invasive cancer), menopausal status of the patients, number of pregnancies, surgeon experience, operating time and cone depth. The data was analyzed with the Chi square test, Fisher's exact test for categorical data and Student's T test for continuous data and univariate and multivariate logistical regressions were performed. A total of 246 medical records have neen analyzed, out of which 29 (11.79%) patients had LSIL, 194 (78.86%) had HSIL and 23 (9.34%) patients suffered micro-invasive/invasive cervical cancer. The surgical margins were positive in 78 (31.7%) of the patients. The average age of the patients was 41.13 and 35 (14.23%) of the patients were menopausal. The multivariate logistic regression identified preoperative forceps biopsy of micro-invasive SCC, HSIL or higher cone specimen histology and shorter cone depth as independent predictors of surgical margin involvement in patients undergoing cold knife conization. In the current study, we have found no association between the inherent characteristics of the patient and the surgeon and the surgical margin state after a CKC. The most important predictors for positive margins were the severity of the lesion and the cone depth.

The prior surgical score estimates the extent of previous surgical intervention by quantitating surgical dissection within 9 abdominopelvic regions. Our aim was to analyze the prognostic significance of the prior surgical score in our cohort of patients undergoing cytoreductive surgery and perioperative intraperitoneal chemotherapy for peritoneal carcinomatosis of a colorectal origin. This was a retrospective analysis of a prospectively maintained database for all patients treated for peritoneal carcinomatosis of a colorectal origin. The prospectively maintained surgical oncology tumor database was analyzed for the study period 1989-2014. A total of 407 patients diagnosed with peritoneal carcinomatosis of a colorectal origin and treated with cytoreductive surgery and perioperative intraperitoneal chemotherapy were included in this analysis. The prognostic significance and clinicopathologic factors associated with an initial nondefinitive surgical intervention in patients with peritoneal carcinomatosis of a colorectal origin undergoing cytoreductive surgery and perioperative intraperitoneal chemotherapy was evaluated. There were 210 men (51.6%) and 197 women (48.4%) in the study. Mean age at presentation was 53.7 years (range, 19.0-87.0 y). Data on prior surgical score for 69 patients were missing, leaving us with a study cohort of 338 patients. Grouped by prior surgical score, 46 (13.6%) had a prior surgical score of 0 versus 25 (7.4%), 122 (36.1%), and 145 (42.9%) who had a prior surgical score of 1, 2, or 3. Overall survival was 53.0%. Three- and 5-year survival rates were 75% and 75% for group prior surgical score 0 versus 26% and 13%, 39% and 37%, and 21% and 16% for group prior surgical scores 1, 2, and 3. Median survival time for the various prior surgical score groups were 180.0, 30.4, 30.5, and 21.3 months for prior surgical scores 0, 1, 2, and 3 (p = 0.000). A total of 87.2% of the prior surgical score 0 group had a completeness of cytoreduction score of 0/1 (no residual disease/tumor <0.25 cm) versus 68.0%, 68.1%, and 48.6% for prior surgical scores of 1, 2, or 3 (p = 0.000). Significant independent predictors of a shorter survival in multivariate analysis included a high cytoreduction score status (p < 0.000) and a high prior surgical score (p = 0.05). This study was limited by its retrospective, population-based design. The extent of a previous nondefinitive surgical intervention contributes to the poor prognosis associated with peritoneal carcinomatosis of a colorectal origin. Independent predictors for an improved overall survival include completeness of cytoreduction and low prior surgical score. See Video Abstract at http://links.lww.com/DCR/A573.

Prophylactic antibiotics to prevent surgical site infection after breast cancer surgery.

PubMed

Bunn, Frances; Jones, Daniel J; Bell-Syer, Sophie

2012-01-18

Surgery has been used as part of breast cancer treatment for centuries; however any surgical procedure has the potential risk of infection. Infection rates for surgical treatment of breast cancer are documented at between 3% and 15%, higher than average for a clean surgical procedure. Pre- and perioperative antibiotics have been found to be useful in lowering infection rates in other surgical groups, yet there is no consensus on the use of prophylactic antibiotics for breast cancer surgery. To determine the effects of prophylactic (pre- or perioperative) antibiotics on the incidence of surgical site infection (SSI) after breast cancer surgery. For this second update we searched the Cochrane Wounds Group Specialised Register (searched 31 August 2011); the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 3); Ovid MEDLINE (2008 to August Week 3 2011); Ovid MEDLINE (In-Process & Other Non-Indexed Citations 30 August 2011); Ovid EMBASE (1980 to 2011 Week 34); and EBSCO CINAHL (2008 to 25 August 2011). We applied no language or date restrictions. Randomised controlled trials of pre- and perioperative antibiotics for patients undergoing surgery for breast cancer were included. Primary outcomes were rates of surgical site infection (SSI) and adverse reactions. Two review authors independently examined the title and abstracts of all studies identified by the search strategy, then assessed study quality and extracted data from those that met the inclusion criteria. A total of nine studies (2260 participants) is included in the review. Eight studies evaluated preoperative antibiotic compared with no antibiotic or placebo. One study evaluated perioperative antibiotic compared with no antibiotic. Pooling of the results demonstrated that prophylactic antibiotics administered preoperatively significantly reduce the incidence of SSI for patients undergoing breast cancer surgery without reconstruction (pooled risk ratio (RR) 0.71, 95% confidence interval (CI) 0.53 to 0.94). Analysis of the single study comparing perioperative antibiotic with no antibiotic found no statistically significant effect of antibiotics on the incidence of SSI (RR 0.11, 95% CI 0.01 to 1.95). No studies presented separate data for patients who underwent reconstructive surgery at the time of removal of the breast tumour. Prophylactic antibiotics administered preoperatively reduce the risk of SSI in patients undergoing surgery for breast cancer. Further studies involving patients undergoing immediate breast reconstruction are needed as studies have identified this group as being at higher risk of infection than those who do not undergo immediate breast reconstruction.

Background Long-term follow-up data concerning isolated tricuspid valve pathology after replacement or reconstruction is limited. Current American Heart Association guidelines equally recommend repair and replacement when surgical intervention is indicated. Our aim was to investigate and compare operative mortality and long-term survival in patients undergoing isolated tricuspid valve repair surgery versus replacement. Material/Methods Between 1995 and 2011, 109 consecutive patients underwent surgical correction of tricuspid valve pathology at our institution for varying structural pathologies. A total of 41 (37.6%) patients underwent tricuspid annuloplasty/repair (TAP) with or without ring implantation, while 68 (62.3%) patients received tricuspid valve replacement (TVR) of whom 36 (53%) were mechanical and 32 (47%) were biological prostheses. Results Early survival at 30 days after surgery was 97.6% in the TAP group and 91.1% in the TVR group. After 6 months, 89.1% in the TAP group and 87.8% in the TVR group were alive. In terms of long-term survival, there was no further mortality observed after one year post surgery in both groups (Log Rank p=0.919, Breslow p=0.834, Tarone-Ware p=0.880) in the Kaplan-Meier Survival analysis. The 1-, 5-, and 8-year survival rates were 85.8% for TAP and 87.8% for TVR group. Conclusions Surgical repair of the tricuspid valve does not show survival benefit when compared to replacement. Hence valve replacement should be considered generously in patients with reasonable suspicion that regurgitation after repair will reoccur. PMID:28236633

To report surgical and functional outcomes of buried penis surgery. Outcomes following buried penis surgery at the University of Washington were assessed from June 1, 2005 to June 1, 2016. Patient demographic and surgical data were abstracted from a retrospective chart review. All patients were attempted to be contacted by phone for long-term follow-up. Uni- and multivariate analysis was performed to evaluate for association with any complication. A total of 42 men underwent buried penis repair surgery (mean short-term follow-up 8.1 months). There was an overall 33% 90-day complication rate (21 events). In univariate analysis, body mass index (BMI; P = .02) and no history of gastric bypass (P = .03) were significant predictors of any complication. In multivariate analysis, only BMI remained significant (odds ratio 1.1 for each increase in unit of BMI, 95% confidence interval 1.01-1.27). Twenty-seven patients were reached for long-term follow-up (mean 39 months). Patients reported improvements in every functional domain that was assessed. Of the patients, 85% reported they would undergo buried penis surgery again, 74% that surgery led to a positive change in their lives, and 85% that the surgery had remained a long-term success. Surgical correction of buried penis with penile split-thickness skin graft and limited panniculectomy is well tolerated and results in functional, long-term improvements. BMI is associated with an increased likelihood of a complication following surgery. Copyright © 2017 Elsevier Inc. All rights reserved.

Correction of the protruded lobule in otoplasty continues to represent an important challenge. The lack of skeletal elements within the lobule makes a controlled lobule repositioning less predictable. OBJECTIVE To present a new surgical technique for lobule correction in otoplasty. Human cadaver studies were performed for detailed anatomical analysis of lobule deformities. In addition, we evaluated a novel algorithmic approach to correction of the lobule in 12 consecutive patients. INTERVENTIONS/EXPOSURES: Otoplasty with surgical correction of lobule using the fillet technique. The surgical outcome in the 12 most recent consecutive patients with at least 3 months of follow-up was assessed retrospectively. The postsurgical results were independently reviewed by a panel of noninvolved experts. The 3 major anatomic components of lobular deformities are the axial angular protrusion, the coronal angular protrusion, and the inherent shape. The fillet technique described in the present report addressed all 3 aspects in an effective way. Clinical data analysis revealed no immediate or long-term complications associated with this new surgical method. The patients' subjective rating and the panel's objective rating revealed "good" to "very good" postoperative results. This newly described fillet technique represents a safe and efficient method to correct protruded ear lobules in otoplasty. It allows precise and predictable positioning of the lobule with an excellent safety profile. 4.

Does omphalocele major undergo spontaneous closure?

PubMed Central

2017-01-01

Abstract The early surgical management of omphalocele major in Africa predisposes neonates to surgical complications which are often worsened by the presence of associated anomalies. Conservative management using available escharotics results in early skin cover by secondary wound healing. This delays the need for fascial closure and avoids neonatal surgical risks thus improving survival. We present a case of omphalocele major that underwent spontaneous closure during conservative management with honey dressing without surgical intervention. PMID:28928917

The purpose of this case-control study was to evaluate the impact of hybrid minimally invasive esophagectomy for cancer on surgical stress response and nutritional status. All 34 consecutive patients undergoing hybrid minimally invasive esophagectomy for cancer at our surgical unit between 2008 and 2013 were retrospectively compared with 34 patients undergoing esophagectomy with open gastric tubulization (open), matched for neoadjuvant therapy, pathological stage, gender and age. Demographic data, tumor features and postoperative course (including quality of life and systemic inflammatory and nutritional status) were compared. Postoperative course was similar in terms of complication rate. Length of stay in intensive care unit was shorter in patients undergoing hybrid minimally invasive esophagectomy (P = 0.002). In the first postoperative day, patients undergoing hybrid minimally invasive esophagectomy had lower C-reactive protein levels (P = 0.001) and white cell blood count (P = 0.05), and higher albumin serum level (P = 0.001). In this group, albumin remained higher also at third (P = 0.06) and seventh (P = 0.008) postoperative day, and C-reactive protein resulted lower at third post day (P = 0.04). Hybrid minimally invasive esophagectomy significantly improved the systemic inflammatory and catabolic response to surgical trauma, contributing to a shorter length of stay in intensive care unit. © 2015 International Society for Diseases of the Esophagus.

Introduction Surgical ablation is a generally established treatment for patients with atrial fibrillation undergoing concomitant cardiac surgery. Left atrial (LA) lesion set for ablation is a simplified procedure suggested to reduce the surgery time and morbidity after procedure. The present meta-analysis aims to explore the outcomes of left atrial lesion set versus no ablative treatment in patients with AF undergoing cardiac surgery. Methods A literature research was performed in six database from their inception to July 2017, identifying all relevant randomized controlled trials (RCTs) comparing left atrial lesion set versus no ablative treatment in AF patient undergoing cardiac surgery. Data were extracted and analyzed according to predefined clinical endpoints. Results Eleven relevant RCTs were included for analysis in the present study. The prevalence of sinus rhythm in ablation group was significantly higher at discharge, 6-month and 1-year follow-up period. The morbidity including 30 day mortality, late all-cause mortality, reoperation for bleeding, permanent pacemaker implantation and neurological events were of no significant difference between two groups. Conclusions The result of our meta-analysis demonstrates that left atrial lesion set is an effective and safe surgical ablation strategy for AF patients undergoing concomitant cardiac surgery.

Although there is a growing body of evidence to document the safety and efficacy of operative treatment of carotid stenosis, surgical indications for elongation and kinking of the internal carotid artery remain controversial. The goal of this study was to evaluate the efficacy of surgical correction of internal carotid artery kinking in patients with persistent hemispheric symptoms despite antiplatelet therapy. A consecutive series of 81 patients (mean age, 64 years) underwent 83 surgical procedures to correct kinking of the internal carotid artery either by shortening and reimplanting the vessel on the common carotid artery, inserting a bypass graft, or transposing the vessel onto the external carotid artery. Mean follow-up was 56 months (range, 15-135 months). Study endpoints were 30-day mortality and any stroke occurring during follow-up. No postoperative death was observed. The postoperative stroke rate was 1%. Primary patency, freedom from neurologic symptoms, and late survival at 5 years (x +/- standard deviation) were 89 +/- 4.1%, 92 +/- 4%, and 71 +/- 6%, respectively. The findings of this study indicate that surgical correction for symptomatic stenotic kinking of the internal carotid artery is safe and effective in relieving symptoms and preventing stroke. Operative correction should be considered as the standard treatment for patients with symptomatic carotid kinking that does not respond to antiplatelet therapy.

Background We report necrotizing scleritis as a serious complication of a cosmetic eye whitening procedure that involves the use of intraoperative and postoperative topical mitomycin C. Findings This is a single case report. A 59-year-old Caucasian male with a history of blepharitis status post uncomplicated LASIK refractive surgery reported chronic conjunctival hyperemia for 15 years prior to undergoing a cosmetic eye whitening procedure. He presented to our clinic 12 months after the cosmetic eye whitening procedure with progressive bilateral necrotizing scleritis and scleral calcification. Conclusions Chronic conjunctival hyperemia may prompt patients to seek surgical correction with cosmetic eye whitening procedures. However, conjunctival hyperemia secondary to tear deficiency and evaporative dry eye may predispose to poor wound healing. Serious complications including necrotizing scleritis may result from cosmetic eye whitening procedures and the use of topical mitomycin C. PMID:23514228

This study explores the association between perioperative hypoglycaemia and surgical outcomes in subjects with diabetes, undergoing colorectal surgery. A retrospective review of 149 subjects with Type 2 Diabetes Mellitus (DM) who underwent colorectal surgery between 2010 and 2015 was performed. Perioperative glucose levels, glycated haemoglobin (HbA1c) measurements within 3 months of surgery and surgical complications based on Clavien-Dindo classification were analysed. The mean age was 67 years (67 ± 11.2). Perioperative hypoglycaemia was found in 7.4% of subjects. The mean HbA1c of subjects with Clavien 2 and above surgical complications were higher than patients with Clavien 1 or no complications, Hba1c 7.6% (7.6 ± 2.5%) and 7.0% (7.0 ± 1.1%, p = 0.008), respectively. Similar findings in subjects with Clavien 3 and above complications, HbA1c of 8.2% (8.2 ± 3.9%) as compared to those with Clavien 2 and below complications, 7.2% (7.2 ± 1.5%, p = 0.001). Adjusted multivariate analysis showed that hypoglycaemia was significantly associated with Clavien 2 and above surgical complications, OR of 19.0 (CI 2.23-162, p = 0.007). Preoperative hypoglycaemia was associated with Clavien 2 and above surgical complications, OR 10.7 (CI 1.22-94.1, p = 0.032). Suboptimal glycaemic control (Hba1c >8.0%) was significantly associated with Clavien 2 and above complications, OR 2.48 (CI 1.04-5.91, p = 0.04), but not with Clavien 3 and above complications, OR 1.50 (CI 0.450-4.98, p = 0.511). Perioperative hypoglycaemia is associated with adverse surgical outcomes in diabetic patients undergoing colorectal surgery. Prevention of hypoglycaemia may improve surgical outcomes. HbA1c is an independent predictor for adverse surgical outcomes.

Patients treated with antithrombotic therapy that require abdominal surgical procedures has progressively increased overtime. The management of antithrombotics during both the peri- and post- operative period is of crucial importance. The goal of this review is to present current data concerning the management of antiplatelets in patients with coronary artery disease and of anticoagulants in patients with atrial fibrillation who had to undergo abdominal surgical operations. For this purpose, incidence of major adverse cardiovascular events (MACE) and risk of antithrombotic use during surgical procedures, as well as the recommendations based on recent guidelines were reported. A thorough search of PubMed, Scopus and the Cochrane Databases was conducted to identify randomized controlled trials, observational studies, novel current reviews, and ESC and ACC/AHA guidelines on the subject. Antithrombotic use in daily clinical practice results to two different pathways: reduction of thromboembolic risk, but a simultaneous increase of bleeding risk. This may cause a therapeutic dilemma during the perioperative period. Nevertheless, careless cessation of antithrombotics can increase MACE and thromboembolic events, however, maintenance of antithrombotic therapy may increase bleeding complications. Studies and current guidelines can assist clinicians in making decisions for the treatment of patients that undergo abdominal surgical operations while on antithrombotic therapy. Aspirin should not be stopped perioperatively in the majority of surgical operations. Determining whether to discontinue the use of anticoagulants before surgery depends on the surgical procedure. In surgical operations with a low risk for bleeding, oral anticoagulants should not be discontinued. Bridging therapy should only be considered in patients with a high risk of thromboembolism. Finally, patients with an intermediate risk for thromboembolism, management should be individualized according to patient's thrombotic and bleeding risk. Management of antithrombotics therapy during the perioperative period in patients undergoing abdominal surgery should follow a patient-centered approach according to a patient's medical history and thrombotic risk weighted for bleeding risk.

Chen, Ching-Chang; Huang, Yin-Cheng; Yeh, Chun-Nan

2015-09-28

Liver cirrhosis, a devastating liver fibrosis caused by hepatitis/inflammation or tumors, is a major comorbid factor in known surgery fields, such as cardiovascular and abdominal surgeries. It is important to review possible comorbid results in neurosurgical procedures in cirrhotic patients. In the reviewed literature, Child-Pugh and model for end-stage liver disease scores are commonly used in the assessment of surgical risks for cirrhotic patients undergoing abdominal, cardiovascular or neurosurgical procedures. The major categories of neurosurgery are traumatic brain injury (TBI), spontaneous intracranial hemorrhage (SICH), brain tumors, and spinal instrumentation procedures. TBI was reported with surgical mortality as high as 34.5% and a complication rate of 87.2%. For SICH, mortality ranged from 22.7% to 47.0%, while complications were reported to be 43.2%. Less is discussed in brain tumor patients; still the postoperative hemorrhage rate approached 26.7%. In spinal fusion instrumentation procedures, the complication rate was as high as 41.0%. Preoperative assessment and correction could possibly decrease complications such as hemorrhage, wound infection and other cirrhosis-related complications (renal, pulmonary, ascites and encephalopathy). In this study, we reviewed the neurosurgical-related literature with regard to liver cirrhosis as a prognostic factor influencing neurosurgical outcomes.

The major categories of neurosurgery are traumatic brain injury (TBI), spontaneous intracranial hemorrhage (SICH), brain tumors, and spinal instrumentation procedures. TBI was reported with surgical mortality as high as 34.5% and a complication rate of 87.2%. For SICH, mortality ranged from 22.7% to 47.0%, while complications were reported to be 43.2%. Less is discussed in brain tumor patients; still the postoperative hemorrhage rate approached 26.7%. In spinal fusion instrumentation procedures, the complication rate was as high as 41.0%. Preoperative assessment and correction could possibly decrease complications such as hemorrhage, wound infection and other cirrhosis-related complications (renal, pulmonary, ascites and encephalopathy). In this study, we reviewed the neurosurgical-related literature with regard to liver cirrhosis as a prognostic factor influencing neurosurgical outcomes. PMID:26413225

To compare the postoperative photoreceptor status and visual outcome after epiretinal membrane removal with or without additional internal limiting membrane (ILM) peeling. Medical records of 40 eyes from 37 patients undergoing epiretinal membrane removal with residual ILM peeling (additional ILM peeling group) and 69 eyes from 65 patients undergoing epiretinal membrane removal without additional ILM peeling (no additional peeling group) were reviewed. The length of defects in cone outer segment tips, inner segment/outer segment junction, and external limiting membrane line were measured using spectral domain optical coherence tomography images of the fovea before and at 1, 3, 6, and 12 months after the surgery. Cone outer segment tips and inner segment/outer segment junction line defects were most severe at postoperative 1 month and gradually restored at 12 months postoperatively. The cone outer segment tips line defect in the additional ILM peeling group was significantly greater than that in the no additional peeling group at postoperative 1 month (P = 0.006), and best-corrected visual acuity was significantly worse in the former group at the same month (P = 0.001). There was no significant difference in the defect size and best-corrected visual acuity at subsequent visits and recurrence rates between the two groups. Patients who received epiretinal membrane surgery without additional ILM peeling showed better visual and anatomical outcome than those with additional ILM peeling at postoperative 1 month. However, surgical outcomes were comparable between the two groups, thereafter. In terms of visual outcome and photoreceptor integrity, additional ILM peeling may not be an essential procedure.

The strong association between congenital heart disease and spinal deformity is well established, but data on the risks and outcome of spinal fusion surgery in patients with congenital heart disease are scarce. The purpose of this study was to identify predictors of perioperative risk and outcome in a large series of children and adolescents with congenital heart disease who underwent spinal fusion for scoliosis or kyphosis. In the authors' retrospective analysis of 74 consecutive patients with congenital heart disease undergoing spinal fusion, there were two deaths (2.7%) and 18 significant complications (24.3%) in the perioperative period. Preoperative cyanosis (arterial oxygen saturation < 90% at rest) with uncorrected or incompletely corrected congenital heart disease was associated with both deaths. Complications occurred in nine of 18 (50%) patients with cyanosis and in 11 of 56 (20%) patients without cyanosis. As judged by multivariate analysis the best predictors of perioperative outcome were the overall physical status of the patient as represented by the American Society of Anesthesiologists' preoperative score and a higher rate of intraoperative blood loss. Seventeen of 43 patients (40%) with an American Society of Anesthesiologists score of 3 or higher experienced complications including two perioperative deaths. Successful spinal fusion and correction were achieved in 97% of patients. Children and adolescents with congenital heart disease can undergo elective spinal fusion with risks that relate to overall cardiac status. Careful assessment of preoperative status by pediatric cardiologists and cardiac anesthesiologists familiar with surgical treatment of patients with congenital heart disease will assist the orthopaedic surgeon in providing the most realistic estimate of risk.

Abdominoplasty (ABP) at the time of hysterectomy (HYS) has been described in the literature since 1986 and is being increasingly requested by patients. However, outcomes of the combined procedure have not been thoroughly explored. The authors reviewed the American College of Surgeons National Surgical Quality Improvement Program database and identified each ABP, HYS, and combined ABP-HYS performed between 2005 and 2012. The incidence of complications in each of the three procedures was calculated, and a multiplicative-risk model was used to calculate the probability of a complication for a patient undergoing distinct HYS and ABP on different dates. One-sample binomial hypothesis tests were performed to determine statistical significance. There were 1325 ABP cases, 12,173 HYS cases, and 143 ABP-HYS cases identified. Surgical complications occurred in 7.7 % of patients undergoing an ABP-HYS, while the calculated risk of a surgical complication was 12.5 % (p = 0.0407) for patients undergoing separate ABP and HYS procedures. The mean operative time was significantly lower for an ABP-HYS at 238 vs. 270 min for separate ABP and HYS procedures (p < 0.0001), and the mean time under anesthesia was significantly lower at 295 vs. 364 min (p < 0.0001). A combined ABP-HYS has a lower incidence of surgical complications than separate ABP and HYS procedures performed on different dates. These data should not encourage all patients to elect a combined ABP-HYS, if only undergoing a HYS, as the combined procedure is associated with increased risks when compared to either isolated individual procedure. However, in patients who are planning on undergoing both procedures on separate dates, a combined ABP-HYS is a safe option that will result in fewer surgical complications, less operative time, less time under anesthesia, and a trend towards fewer days in the hospital.

Background The Ponseti method of congenital idiopathic clubfoot correction has traditionally specified plaster of Paris (POP) as the cast material of choice; however, there are negative aspects to using POP. We sought to determine the influence of cast material (POP v. semirigid fibreglass [SRF]) on clubfoot correction using the Ponseti method. Methods Patients were randomized to POP or SRF before undergoing the Ponseti method. The primary outcome measure was the number of casts required for clubfoot correction. Secondary outcome measures included the number of casts by severity, ease of cast removal, need for Achilles tenotomy, brace compliance, deformity relapse, need for repeat casting and need for ancillary surgical procedures. Results We enrolled 30 patients: 12 randomized to POP and 18 to SRF. There was no difference in the number of casts required for clubfoot correction between the groups (p = 0.13). According to parents, removal of POP was more difficult (p < 0.001), more time consuming (p < 0.001) and required more than 1 method (p < 0.001). At a final follow-up of 30.8 months, the mean times to deformity relapse requiring repeat casting, surgery or both were 18.7 and 16.4 months for the SRF and POP groups, respectively. Conclusion There was no significant difference in the number of casts required for correction of clubfoot between the 2 materials, but SRF resulted in a more favourable parental experience, which cannot be ignored as it may have a positive impact on psychological well-being despite the increased cost associated.

Determine the occurrence of dysphagia symptoms in children with cleft lip and/or palate (CLP) pre- and post-surgical correction. Quantitative observational cross-sectional study. Existence of clef lip and/or palate without association with other syndromes was the study inclusion and/or exclusion criterion. Parents and/or legal guardians responded to a recall questionnaire on the identification of occurrence of coughing, choking, vomiting, and nasal escape pre- and postoperatively and whether these symptoms disappeared after surgical correction. The study was approved by the Research Ethics Committee of the aforementioned Institution under protocol no. 1573164. The sample comprised 23 children with mean age of 48 months, mostly male and with unilateral trans-foramen incisor clefts. Statistically significant difference was observed between the pre- and post-surgical periods regarding the presence of dysphagia symptoms. Surgical treatment of patients with cleft lip and/or palate proved to be a resource to prevent the occurrence of dysphagia symptoms when associated with adequate intervention chronology.

To evaluate whether opportunistic salpingectomy in premenopausal women undergoing hysterectomy for benign indications is both hormonally and surgically safe, compared with hysterectomy without salpingectomy. In this multicentre randomised controlled trial, women were randomised to undergo either hysterectomy with opportunistic bilateral salpingectomy (intervention group) or standard hysterectomy with preservation of the Fallopian tubes (control group). The primary outcome was the difference in serum anti-Müllerian hormone concentration (ΔAMH), measured pre-surgery and 6 months post-surgery. Secondary outcomes were surgical outcomes and duration of hospital stay. The sample size was powered at 50 participants per group (n=100) to compare ΔAMH after hysterectomy with salpingectomy to ΔAMH after standard hysterectomy. Between March 2013 and December 2016, 104 women, aged 30-55 years, were randomly allocated to hysterectomy with opportunistic bilateral salpingectomy (n=52) or standard hysterectomy (n=52). The baseline characteristics did not differ between the two groups. The median ΔAMH was -0.14pmol/L (IQR -1.47-0.95) in the intervention group and 0.00pmol/L (IQR -1.05-0.80) in the control group (p=0.49). The addition of salpingectomy did not impair surgical results and it did not affect duration of hospital stay. Addition of opportunistic bilateral salpingectomy during hysterectomy did not result in a larger effect on ovarian reserve when compared with hysterectomy alone, neither did it affect surgical outcomes. Therefore, opportunistic salpingectomy seems to be a safe procedure in premenopausal women undergoing hysterectomy for benign gynaecological conditions. Copyright © 2017 Elsevier B.V.

The purpose of this study was to evaluate the outcomes for elderly (> or =80 years) patients undergoing aortic valve replacement (AVR) with or without coronary artery bypass graft surgery (AVR/CABG). The authors hypothesized that the mortalities of AVR and AVR/CABG are lower than that predicted by published risk scores. A retrospective analysis of data from a single-hospital database. Single tertiary care, private practice. Consecutive patients undergoing AVR or AVR/CABG. Two hundred sixty-one elderly (> or =80 years) patients undergoing isolated AVR (145) or AVR/CABG (116) were evaluated. The majority (94.6%) underwent AVR for aortic valve stenosis. Outcomes were recorded and compared between the 2 surgical procedures with predicted mortalities based on published risk assessment scoring systems. The overall short-term mortality for the elderly group was 6.1% (AVR 5.5% and AVR/CABG 6.9%). The median long-term survival was 6.8 years. There were no significant differences in either morbidity or mortality between the AVR and AVR/CABG groups. Although predicted mortalities were similar for each surgical procedure, they overestimated observed outcome by up to 4-fold. Short- and long-term mortality was low for this group of elderly patients undergoing AVR or AVR/CABG and not significantly different between the 2 surgical groups. Predicted outcomes were worse than that observed, consistent with the hypothesis, and supportive of a more aggressive surgical treatment for aortic valve disease in the elderly patient.

2018-03-23

Patients with Williams syndrome are considered at high risk for anesthesia-related adverse events. At our institution, all William syndrome patients undergoing cardiac surgical, cardiac catheterization/interventional procedures, and cardiac imaging studies are cared for by cardiac anesthesiologists. All William syndrome patients undergoing non-cardiac surgical, interventional, or imaging studies are cared for by main operating room pediatric anesthesiologists with consultative input from a cardiac anesthesiologist. We reviewed our experience with 75 patients undergoing 202 separate anesthetics for 95 non-cardiac procedures and 107 cardiac procedures from 2012 to 2016. The mean age was 7.5 ± 7.0 years and the mean weight was 22.3 ± 17.0 kg. One hundred and eighty-seven patients had a general anesthetic (92.6%). Medications used included etomidate in 26.2%, propofol in 37.6%, isoflurane in 47.5%, and sevoflurane in 68.3%. Vasopressors and inotropes were required including calcium (22.8%), dopamine (10.4%), norepinephrine (17.3%), phenylephrine (35.1%), vasopressin (0.5%), and ephedrine (5.4%). The median length of stay after anesthesia was 2.8 days (range 0-32). No adverse events occurred in 89.6% of anesthetics. There were two cases of cardiac arrest, one of which required extracorporeal life support for resuscitation. Of the non-cardiac surgical procedures, 95.7% did not have a cardiovascular adverse event. Patients with Williams syndrome are at high risk for anesthesia, especially when undergoing cardiac procedures. The risk can be mitigated with appropriate planning and adherence to the hemodynamic goals for non-cardiac surgical procedures.

In total surgical correction of tetralogy of Fallot (TOF) with functioning Blalock Taussig shunts (BTS), shunt take down increased surgical time, bleeding, and might injure phrenic and recurrent laryngeal nerve and thoracic duct. A routine hybrid approach using transcatheter BTS closure immediately before total surgical correction of TOF in all patients might reduce these problems. We analyze the safety and feasibility of this approach. Transcatheter BTS closure was achieved using single or multiple stainless steel embolization coils, Amplatzer vascular plugs, or duct occluders. When coils were released without control by bioptome forceps, coil migration in larger shunts was prevented by proximal or distal balloon occlusion. This routine hybrid strategy was followed in 22 consecutive patients aged 1-13 years over 4-year-period and 21 procedures were successful. Among the 16 patients attempted with coils, 13 had successful closure, 2 needed Amplatzer duct occluder devices, and 1 sent for surgical shunt takedown due to acute angulation of the shunt. New Amplatzer vascular plugs were used in six patients. Bioptome was used in six patients and proximal or distal balloon occlusion of flow was used in three patients. Four patients had closure of associated aortopulmonary or chest wall collaterals. Hybrid approach using routine transcatheter closure of all BTS immediately before surgical correction of TOF shunts with coils/plugs/devices is safe, feasible, and reproducible.

Malnutrition is common in children with congenital heart disease (CHD), especially in developing countries. To examine the impact of corrective intervention on the nutritional status of children with CHD and identify factors associated with suboptimal recovery. Consecutive patients with CHD in a tertiary center in South India were evaluated for nutritional status before and 2 years after corrective intervention. Anthropometry was performed at presentation and every 6 months for 2 years, and z scores were compared. Malnutrition was defined as a weight-for-age, height-for-age, and weight/height z score <-2. Determinants of malnutrition were entered into a multivariate logistic regression analysis model. Of 476 patients undergoing corrective intervention (surgical: 344; catheter-based: 132) z scores of less than -2 for weight for age, height for age, and weight/height were recorded in 59%, 26.3%, and 55.9% of patients, respectively, at presentation. On follow-up (425 patients [92.5% of survivors; 20.63 +/- 13.1 months of age]), z scores for weight for age and weight/height improved significantly from the baseline (weight: -1.42 +/- 1.03 vs -2.19 +/- 1.16; P < .001; weight/height: -1.15 +/- 1.25 vs -2.09 +/- 1.3; P < .001). Height-for-age z scores were not significantly different. Malnutrition persisted in 116 (27.3%) patients on follow-up and was associated with a birth weight of

Cryptotia is a congenital auricular deformity in which the upper third of the auricle is buried under the temporal skin. There is no standard surgical method to correct cryptotia. This study is aimed at devising a new surgical method to correct cryptotia with good auricular contour and inconspicuous scar. We retrospectively reviewed 8 patients diagnosed with cryptotia in West China Hospital between 2006 and 2009. All of them received this new surgical method to correct cryptotia. The follow-up period ranged from 6 months to 1 year. All patients possessed good auricular contour and sufficient skin for release of the upper part of the auricle without the need for a skin graft or local skin flap transferred. All patients possessed deep auriculotemporal sulci and inconspicuous scars. There were no complications, and cryptotia did not recur in any patient.

Patients with temporal lobe epilepsy (TLE) experience significant deficits in category-related object recognition and naming following standard surgical approaches. These deficits may result from a decoupling of core processing modules (e.g., language, visual processing, and semantic memory), due to "collateral damage" to temporal regions outside the hippocampus following open surgical approaches. We predicted that stereotactic laser amygdalohippocampotomy (SLAH) would minimize such deficits because it preserves white matter pathways and neocortical regions that are critical for these cognitive processes. Tests of naming and recognition of common nouns (Boston Naming Test) and famous persons were compared with nonparametric analyses using exact tests between a group of 19 patients with medically intractable mesial TLE undergoing SLAH (10 dominant, 9 nondominant), and a comparable series of TLE patients undergoing standard surgical approaches (n=39) using a prospective, nonrandomized, nonblinded, parallel-group design. Performance declines were significantly greater for the patients with dominant TLE who were undergoing open resection versus SLAH for naming famous faces and common nouns (F=24.3, p<0.0001, η2=0.57, and F=11.2, p<0.001, η2=0.39, respectively), and for the patients with nondominant TLE undergoing open resection versus SLAH for recognizing famous faces (F=3.9, p<0.02, η2=0.19). When examined on an individual subject basis, no SLAH patients experienced any performance declines on these measures. In contrast, 32 of the 39 patients undergoing standard surgical approaches declined on one or more measures for both object types (p<0.001, Fisher's exact test). Twenty-one of 22 left (dominant) TLE patients declined on one or both naming tasks after open resection, while 11 of 17 right (nondominant) TLE patients declined on face recognition. Preliminary results suggest (1) naming and recognition functions can be spared in TLE patients undergoing SLAH, and (2) the hippocampus does not appear to be an essential component of neural networks underlying name retrieval or recognition of common objects or famous faces.

In the specialty of surgical hair restoration, men comprise more than 90% of the patients treated; however, in the last few years the number of women undergoing the procedure has increased significantly. The reasons for this growth are many and include the increase in public awareness of the efficacy of hair transplantation from such sources as the media,the Internet, advertising and word of mouth. More importantly, advances in technique have significantly improved results, increasing the confidence level in women to undergo the procedure and in hair transplant specialists to offer it.

Leg ischemia is a serious complication of femoral artery cannulation. The primary aim of this study was to assess the safety and efficacy of a novel bidirectional femoral arterial cannula (Sorin Group USA, a wholly owned subsidiary of LivaNova PLC, Arvada, CO USA) that provides both antegrade and retrograde flow, in patients undergoing peripheral cannulation for cardiopulmonary bypass during cardiac surgery. Patients undergoing routine cardiac surgery requiring femoral artery cannulation for cardiopulmonary bypass were identified preoperatively. Informed written consent was obtained in all cases. Bidirectional cannula insertion used either a surgical cut-down and wire through needle approach or a percutaneous technique. Flow in the superficial femoral artery was assessed using Doppler ultrasound after commencement of cardiopulmonary bypass. Lower limb perfusion was assessed using reflectance near-infrared spectroscopy to measure regional oxygen saturations in the cannulated limb during cardiopulmonary bypass. Fifteen patients (median age = 61.3 years, range = 26-79 years, 10 males, 5 females) underwent femoral arterial cannulation using the novel bidirectional femoral cannula between August 2016 and May 2017. Fourteen cannulae were inserted directly into the femoral artery via a surgical cut-down and wire through needle technique. One bidirectional cannula was inserted using a percutaneous insertion technique. Indications included minimally invasive mitral and aortic valve surgery, thoracic aortic aneurysm repair, and redo cardiac surgery. The median duration of cardiopulmonary bypass was 129 minutes (range = 53-228 minutes). The cannula was inserted and positioned without difficulty in 14 of 15 patients. Incorrect sizing and arterial spasm prevented correct cannula positioning in one patient. Antegrade flow in the superficial femoral artery was observed on Doppler ultrasound in 12 of 12 patients in which this was performed. Continuous stable distal perfusion was demonstrated in the cannulated limb in 14 of 15 patients. No procedural complications occurred in the immediate or convalescent postoperative period. This study demonstrates that in patients undergoing femoral arterial cannulation for cardiopulmonary bypass during cardiac surgery, the use of a novel bidirectional cannula is safe and easy to insert and provides stable distal perfusion of the cannulated limb. Use of the device should largely obviate the need to insert a separate downstream perfusion cannula or use other techniques to protect against lower limb ischemia. Further research on a larger scale and in different patient populations is now warranted.

Among surgical oncology patients, incisional surgical site infection is associated with substantially increased morbidity, mortality and healthcare costs. Moreover, while adults undergoing pancreaticoduodenectomy with preoperative placement of an intrabiliary stent have a high risk of this type of infection, and wound protectors may significantly reduce its risk, no relevant studies of wound protectors yet exist involving this patient population. This study will evaluate the efficacy of a dual-ring wound protector for prevention of incisional surgical site infection among adults undergoing pancreaticoduodenectomy with preoperatively-placed intrabiliary stents. This study will be a parallel, dual-arm, randomised controlled trial that will utilise a more explanatory than pragmatic attitude. All adults (≥18 years) undergoing a pancreaticoduodenectomy at the Foothills Medical Centre in Calgary, Alberta, Canada with preoperative placement of an intrabiliary stent will be considered eligible. Exclusion criteria will include patient age <18 years and those receiving long-term glucocorticoids. The trial will employ block randomisation to allocate patients to a commercial dual-ring wound protector (the Alexis Wound Protector) or no wound protector and the current standard of care. The main outcome measure will be the rate of surgical site infection as defined by the Centers for Disease Control and Prevention criteria within 30 days of the index operation date as determined by a research assistant blinded to treatment allocation. Outcomes will be analysed by a statistician blinded to allocation status by calculating risk ratios and 95% CIs and compared using Fisher's exact test. This will be the first randomised trial to evaluate the efficacy of a dual-ring wound protector for prevention of incisional surgical site infection among patients undergoing pancreaticoduodenectomy. Results of this study are expected to be available in 2016/2017 and will be disseminated using an integrated and end-of-grant knowledge translation strategy.

Abstract The objective of this study was to determine the 30-day incidence of ischemic stroke following neck dissection compared to matched patients undergoing non-head and neck surgeries. A surgical dissection of the neck is a common procedure performed for many types of cancer. Whether such dissections increase the risk of ischemic stroke is uncertain. A retrospective cohort study using data from linked administrative and registry databases (1995–2012) in the province of Ontario, Canada was performed. Patients were matched 1-to-1 on age, sex, date of surgery, and comorbidities to patients undergoing non-head and neck surgeries. The primary outcome was ischemic stroke assessed in hospitalized patients using validated database codes. A total of 14,837 patients underwent surgical neck dissection. The 30-day incidence of ischemic stroke following the dissection was 0.7%. This incidence decreased in recent years (1.1% in 1995 to 2000; 0.8% in 2001 to 2006; 0.3% in 2007 to 2012; P for trend <0.0001). The 30-day incidence of ischemic stroke in patients undergoing neck dissection is similar to matched patients undergoing thoracic surgery (0.5%, P = 0.26) and colectomy (0.5%, P = 0.1). Factors independently associated with a higher risk of stroke in 30 days following neck dissection surgery were of age ≥75 years (odds ratio (OR) 1.63, 95% confidence interval (CI) 1.05–2.53), and a history of diabetes (OR 1.60, 95% CI 1.02–2.49), hypertension (OR 2.64, 95% CI 1.64–4.25), or prior stroke (OR 4.06, 95% CI 2.29–7.18). Less than 1% of patients undergoing surgical neck dissection will experience an ischemic stroke in the following 30 days. This incidence of stroke is similar to thoracic surgery and colectomy.

The purpose of this article is to summarize the work and pioneering achievements in the field of orthopedic surgery of the German orthopedic surgeon Karl Ludloff. Ludloff had an impact in the diagnostics, physical examination, orthopedic imaging, and orthopedic surgical technique of his era. He was a pioneer in the surgical treatment of dysplastic hip, anterior cruciate ligament reconstruction, and hallux valgus. His surgical technique for the correction of hallux valgus, initially stabilized with plaster of Paris, remained unpopular among other orthopedic surgeons for decades. In the 1990s, the advent and use of improved orthopedic materials for fixation attracted the interest of numerous orthopedic surgeons in the Ludloff osteotomy for its ability to correct the deformity in all 3 dimensions, its anatomic outcomes, and its low recurrence rate and patient satisfaction.

Peyronie's disease (PD) is a debilitating disorder in which collagen deposition, fibrosis, and plaques in the tunica albuginea result in penile curvature, shortening, and pain. For severe curvatures requiring plaque incision or excision with grafting (PIEG), a subcoronal circumcising incision with penile degloving has historically been used. The aim of this study was to report our unique approach to PIEG via a longitudinal "window" incision for the correction of PD, minimizing the surgical manipulation and dissection accompanying the traditional circumcising incisional approach that may lead to increased postoperative edema, pain, and prolonged healing time. A patient presented with a stable, painless, 90-degree midshaft leftward curvature causing penetration difficulties and painful intercourse for his partner. His Sexual Health Inventory for Men (SHIM) score was 23. The patient opted for surgical correction with plaque excision and grafting via a 4-cm longitudinal incision overlying the point of maximal curvature along the left lateral penile shaft. This direct access to the left corpus cavernosum and plaque, along with dissecting skin, dartos, and Buck's fascia, created a window with sufficient exposure for excision and patch grafting. The main outcome measures were objective data and subjective data in men undergoing PIEG via lateral longitudinal "window" incision for PD repair. The plaque was excised and a porcine small intestinal submucosa graft was sewn in. Intraoperative artificial tumescence at the end of surgery revealed complete correction of the curvature. The patient experienced painless rigid erections by postoperative day three with minimal penile edema. By postoperative week four, he could successfully partake in coitus. His SHIM score remained unchanged. At maximum follow-up 6 months postoperatively, he still endorsed excellent cosmetic and functional outcomes with spontaneous unassisted erections and no recurrence of his curvature. A lateral longitudinal incision for PIEG is a feasible technique and may reduce the postoperative morbidity and dissection required with traditional circumcising incision with penile degloving. Larger comparative studies are necessary for further evaluation.

Retrospective clinical outcome study. To evaluate the clinical outcomes and satisfaction associated with the surgical treatment of neuromuscular spinal deformity secondary to cerebral palsy. Controversy still exists regarding whether spinal deformity surgery is truly a beneficial surgery for patients with cerebral palsy (CP) since there is limited functional benefit and higher perioperative complications rates in this patient population. Neuromuscular patient evaluation questionnaires were answered retrospectively by 84 patients/families of spastic CP patients undergoing spinal fusion. The average follow-up was 6.2 years (range: 2-16). The questionnaires were designed to assess expectation, cosmesis, function, patient care, quality of life, pulmonary function, pain, health status, self-image, and satisfaction. Questionnaire results, complications, and radiographic data were divided into "satisfied group" and "less satisfied group" and we analyzed reasons of satisfaction and dissatisfaction. The overall satisfaction rate was 92%. Ninety-three percent reported improvement with sitting balance, 94% with cosmesis, and 71% in patient's quality of life. Functional improvements seemed limited, but 8% to 40% of the patients still perceived the surgical results as improvement. The postoperative complication rate was 27%. The mean preoperative Cobb angle of the major curve was 88 degrees (range: 53 degrees-141 degrees), which corrected to 39 degrees (range: 5 degrees-88 degrees) after surgery. The less satisfied group had a significantly higher late complication rate, less correction of the major curve, greater residual major curve, and hyperlordosis of the lumbar spine after surgery. Despite the perioperative difficulties seen with CP patients, the majority of the patient/parents were satisfied with the results of the spinal deformity surgery. Functional improvements were limited but 8% to 40% of the patients still perceived the results as improved. The reason for less than optimal satisfaction appears to be due to less correction of the major curve, greater residual major Cobb angle, hyperlordosis of the lumbar spine after surgery, and late postoperative complications.

Risk factors associated with surgical site infection (SSI) and the development of short-term complications in macaques undergoing vascular access port (VAP) placement are evaluated in this study. Records from 80 macaques with VAPs were retrospectively reviewed. Logistic regression was used to identify factors associated with short-term post-operative complications. The primary outcome was SSI, which occurred in 21.6% (52.6% in the first 12 months vs. 13% thereafter) of procedures. SSI was associated with major secondary complications including VAP removal (11.4%), wound dehiscence (5.7%), and mechanical catheter occlusion (5.7%). In multivariate modeling, only surgical program progress was a statistically significant predictor of SSI, while animal compliance had a slightly protective effect. Vascular access ports have a moderate risk of complications, provided the surgical program optimizes best practices. Under complex experimental conditions, VAPs represent an important refinement, both improving animals' overall well-being and environment and reducing stress.

Adhesions small bowel obstructions (aSBO) are among the leading causes of emergency operative intervention. About the 80% of aSBO cases resolve without a surgical treatment. It's important to identify which patients could undergo a conservative treatment to prevent an useless surgery The aim of this study is to determine findings that can indicate whether patients with aSBO should undergo a conservative or a surgical treatment. 313 patients with diagnosis of submission of aSBO were restudied. Patients were divided into two groups based on the different type of treatment received, 225 patients who underwent surgical treatment within 24 hours after admission, 88 patients which underwent conservative treatment successfully. For each patient, clinical, hematochemical and radiological findings have been analysed. The treatment of aSBO should be, at the beginning, conservative except that cases that presents clinical and/or CT-scan findings predictive for a surgical treatment (free peritoneal fluid, mesenterial edema, transitional point) or a peritonitis (pneumatosis intestinalis, pneumoperitoneum).

Multi center data regarding cardiac arrest in children undergoing heart operations of varying complexity are limited. Children <18 years undergoing heart surgery (with or without cardiopulmonary bypass) in the Virtual Pediatric Systems (VPS, LLC) Database (2009-2014) were included. Multivariable mixed logistic regression models were adjusted for patient's characteristics, surgical risk category (STS-EACTS Categories 1, 2, and 3 classified as "low" complexity and Categories 4 and 5 classified as "high" complexity), and hospital characteristics. Overall, 26,909 patients (62 centers) were included. Of these, 2.7% had cardiac arrest after cardiac surgery with an associated mortality of 31%. The prevalence of cardiac arrest was lower among patients undergoing low complexity operations (low complexity vs. high complexity: 1.7% vs. 5.9%). Unadjusted outcomes after cardiac arrest were significantly better among patients undergoing low complexity operations (mortality: 21.6% vs. 39.1%, good neurological outcomes: 78.7% vs. 71.6%). In adjusted models, odds of cardiac arrest were significantly lower among patients undergoing low complexity operations (OR: 0.55, 95% CI: 0.46-0.66). Adjusted models, however, showed no difference in mortality or neurological outcomes after cardiac arrest regardless of surgical complexity. Further, our results suggest that incidence of cardiac arrest and mortality after cardiac arrest are a function of patient characteristics, surgical risk category, and hospital characteristics. Presence of around the clock in-house attending level pediatric intensivist coverage was associated with lower incidence of post-operative cardiac arrest, and presence of a dedicated cardiac ICU was associated with lower mortality after cardiac arrest. This study suggests that the patients undergoing high complexity operations are a higher risk group with increased prevalence of post-operative cardiac arrest. These data further suggest that patients undergoing high complexity operations can be rescued after cardiac arrest with a high survival rate. Copyright © 2016 Elsevier Ireland Ltd.

WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Surgical correction of the congenital completely buried penis (CCBP) is a difficult challenge and there is no unanimous consensus about the surgical 'gold standard' and patient eligibility for surgery. In the present study, dysgenetic fundiform ligaments were found to be attached to the distal or middle shaft of the penis. This abnormality can be successfully corrected by releasing the fundiform ligament and mobilising the scrotal skin to cover the length of the penile shaft. The study shows that the paucity and traction of the penile skin and an abnormal fundiform ligament are important anatomical defects in CCBP. Dorsal curve and severe shortage of penile skin in erectile conditions are the main indications for surgical correction. To present our experience of anatomical findings for congenital completely buried penis (CCBP), which has no unanimous consensus regarding the 'gold standard' for surgical correction and patient eligibility, by providing our surgical technique and illustrations. Between February 2006 and February 2011, 22 children with a median (range) age of 4.2 (2.5-5.8) years, with CCBP underwent surgical correction by one surgeon. Toilet training and photographs of morning erections by parents were advised before surgery. The abnormal anatomical structure of buried penis during the operation was observed. The technique consisted of the release of the fundiform ligament, fixation of the subcutaneous penile skin at the base of the degloved penis, penoscrotal Z-plasty and mobilisation of the penile and scrotal skin to cover the penile shaft. In reflex erectile conditions, CCBP presents varying degrees of dorsal curve and shortage of penile skin. Dysgenetic fundiform ligaments were found to be attached to the distal or middle shaft of the penis in all patients. All wounds healed well and the cosmetic outcome was good at 6-month follow-up after the repair. The appearance of the dorsal curve in CCBP mainly results from the traction of penile dorsal skin and the abnormal attachment of the fundiform ligament to the shaft. This abnormality can be successfully corrected by releasing the abnormal fundiform ligament and mobilising scrotal skin to cover the length of the penile shaft. © 2013 BJU International.

Objective To evaluate the effect of preoperative anaemia and blood transfusion on 30-day postoperative morbidity and mortality in patients undergoing gynecological surgery. Study Design Data were analyzed from 12,836 women undergoing operation in the American College of Surgeons National Surgical Quality Improvement Program. Outcomes measured were; 30-day postoperative mortality, composite and specific morbidities (cardiac, respiratory, central nervous system, renal, wound, sepsis, venous thrombosis, or major bleeding). Multivariate logistic regression models were performed using adjusted odds ratios (ORadj) to assess the independent effects of preoperative anaemia (hematocrit <36.0%) on outcomes, effect estimates were performed before and after adjustment for perioperative transfusion requirement. Results The prevalence of preoperative anaemia was 23.9% (95%CI: 23.2–24.7). Adjusted for confounders by multivariate logistic regression; preoperative anaemia was independently and significantly associated with increased odds of 30-day mortality (OR: 2.40, 95%CI: 1.06–5.44) and composite morbidity (OR: 1.80, 95%CI: 1.45–2.24). This was reflected by significantly higher adjusted odds of almost all specific morbidities including; respiratory, central nervous system, renal, wound, sepsis, and venous thrombosis. Blood Transfusion increased the effect of preoperative anaemia on outcomes (61% of the effect on mortality and 16% of the composite morbidity). Conclusions Preoperative anaemia is associated with adverse post-operative outcomes in women undergoing gynecological surgery. This risk associated with preoperative anaemia did not appear to be corrected by use of perioperative transfusion. PMID:26147954

Significant portions of patients undergoing colorectal surgical procedures have minor incision disturbances, yet very few meet definitions for surgical site infection (SSI). We sought to investigate the natural history of incision disturbances with a focus on the patient experience and resource utilization. We hypothesize that patients who have an incision disturbance consume frequent healthcare resources in the post-operative period despite the fact that most never receive a diagnosis of SSI. A 24-month prospective observational study was undertaken at an academic institution. Patients undergoing elective colorectal operation by two board-certified colorectal surgeons were followed prospectively for 90 days. Incisions were photographed serially and clinically characterized beginning as early as post-operative day two and at follow-up visits. The primary outcome was patient concern for an incision disturbance. Three surgeons reviewed clinical data and photographs to determine the presence of an incisional surgical infection, and diagnosis required agreement from two of three surgeons. There were 171 patients included; 31 (15%) sought evaluation from a healthcare provider for concerns related to their incision including 46 telephone calls, six emergency department visits, seven primary care visits, 10 home health and 40 surgical clinic visits. Incision erythema and drainage were the most common sources of patient concern. Mean body mass index was higher in patients with concern for incision disturbances (34 vs. 28 kg/m 2 , p < 0.0001). Ultimately, 8% (14/171) received a diagnosis of SSI by study criteria while only 2% (4/171) were captured as having an SSI by the institutional National Surgical Quality Improvement Program database (p < 0.0001). Patients undergoing colorectal surgical procedures commonly are concerned with post-operative incision disturbance, yet few are associated with a diagnosis of SSI, and in-person evaluation yields frequent utilization of healthcare resources. This presents an opportunity for secure electronic communication with the surgical team and the patient to potentially reduce consumption of healthcare resources.

"Buried penis" is an increasing burden in our population with many possible etiologies. Although surgical correction of buried penis can be rewarding and successful for the surgeon, the psychological and functional impact of buried penis on the patient is less understood. The study's aim was to evaluate the sexual satisfaction and overall quality of life before and after buried penis surgery in a single-surgeon's patient population using a validated questionnaire (Changes in Sexual Functioning Questionnaire short-form). Using Likert scales generated from the questionnaire and 1-tailed paired t test analysis, we found that there was significantly improved sexual function after correction of a buried penis. Variables individually showed that there was significant improvement with sexual pleasure, urinating, and with genital hygiene postoperatively. There were no significant differences concerning frequency of pain with orgasms. Surgical correction of buried penis significantly improves the functional, sexual, and psychological aspects of patient's lives.

Surgical repair of pectus excavatum and carinatum.

Robicsek, Francis; Watts, Larry T; Fokin, Alexander A

2009-01-01

The author discusses different forms of pectus deformities and presents appropriate surgical methods he developed for their correction. For pectus excavatum, the surgical technique includes conservative sub-perichondral resection of deformed costal cartilages and detachment of the xiphoid process. A transverse sternotomy is performed at the upper level of the deformed sternum, which is then bent forward. The corrected sternal position is secured by a "hammock" of synthetic mesh, spread behind the sternum, and attached to the respective cartilage remnants. The pectoralis muscles are then united presternally. The initial steps of pectus carinatum correction are similar to that of pectus excavatum. The sternum, however, is not freed of its environment. A length of 3-4 cm is resected from the distal sternum and the xiphoid process is reattached in the proper anatomical direction. Measures to correct different anatomical varieties, such as pouter pigeon breast, asymmetrical pectus excavatum, and carinatum, are discussed individually.

A pragmatic multi-centre randomised controlled trial of fluid loading and level of dependency in high-risk surgical patients undergoing major elective surgery: trial protocol

PubMed Central

2010-01-01

Background Patients undergoing major elective or urgent surgery are at high risk of death or significant morbidity. Measures to reduce this morbidity and mortality include pre-operative optimisation and use of higher levels of dependency care after surgery. We propose a pragmatic multi-centre randomised controlled trial of level of dependency and pre-operative fluid therapy in high-risk surgical patients undergoing major elective surgery. Methods/Design A multi-centre randomised controlled trial with a 2 * 2 factorial design. The first randomisation is to pre-operative fluid therapy or standard regimen and the second randomisation is to routine intensive care versus high dependency care during the early post-operative period. We intend to recruit 204 patients undergoing major elective and urgent abdominal and thoraco-abdominal surgery who fulfil high-risk surgical criteria. The primary outcome for the comparison of level of care is cost-effectiveness at six months and for the comparison of fluid optimisation is the number of hospital days after surgery. Discussion We believe that the results of this study will be invaluable in determining the future care and clinical resource utilisation for this group of patients and thus will have a major impact on clinical practice.

Prosthetic joint infection (PJI) remains a major complication after total joint replacement and is the primary indication for revision arthroplasty. Specifically, coagulase-negative Staphylococci (CNS) can cause low-grade infections. Despite the use of cephalosporin-based antimicrobial prophylaxis (AMP) and antiseptic treatment at the surgical site, evidence suggests that a significant number of cases of dermal CNS results in low-grade PJI. Thus, this study examined the bacterial colonization and resistance patterns at the surgical site. We hypothesized that the bacteria developed resistance to antibiotics that are frequently used in primary and revision total hip arthroplasty (THA) procedures. Ninety patients, including 63 primary and 27 revision THA patients, were enrolled in this study. For each patient, a single swab of the skin at the surgical site was subjected to clinical microbiology to assess bacterial colonization. Furthermore, resistance to a sentinel panel of antibiotics (benzylpenicillin, erythromycin, tetracycline, oxacillin, fusidic acid, clindamycin, gentamicin, levofloxacin/moxifloxacin, rifampicin, linezolid and vancomycin) was tested. In 96.7% of the patients, at least one bacterial strain was identified at the surgical site, with CNS strains comprising 93.1% of the total. The sentinel panel showed that 30.7% of the CNS strains exhibited maximal resistance to oxacillin, a commonly used cephalosporin. Additionally, oxacillin resistance increased 1.9-fold (p=0.042) between primary and revision THA. Notably, 8.1% of the CNS stains found on patients undergoing primary THA were resistant to gentamicin, an aminoglycoside, and this rate increased 4.7-fold (p=0.001) for patients undergoing revision THA. CNS strains have significant resistance to standard AMP, particularly in individuals undergoing revision THA. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

Recently, the AJCC has released its 8th edition changes to the staging system for intrahepatic cholangiocarcinoma (iCCA). This study sought to validate the proposed changes to the 8th edition of AJCC system for T and N classification of iCCA using a population-based data set. Using the Surveillance, Epidemiology, and End Results (SEER) database (1998-2013), patients undergoing resection or non-surgical management for non-metastatic iCCA were identified. Overall survival was estimated using the Kaplan-Meier method and compared using log-rank tests. Concordance indices (c-indices) calculated from Cox proportional hazards models were calculated to evaluate discriminatory power. The study included 2630 patients resected (37%) or non-surgically managed (63%) for iCCA. Nodal staging was performed in 56%, of whom 31% had positive nodes. For all patients with iCCA, the median 5-year survival by AJCC T classification for T1a, T1b, T2, T3, and T4 was 32, 21, 14, 10, and 10 months, respectively (p < 0.001). The concordance index for the staging system was 0.57 for all patients, 0.62 for those who underwent resection, and 0.54 for patients who did not undergo resection. In summary, the new AJCC 8th edition staging system is comparable to the 7th edition and valid in stratifying patients with iCCA. However, the performance of the staging system is better in patients undergoing surgical resection than those undergoing non-surgical management. These findings further highlight the need for improved accuracy of radiological imaging in clinically staging patients to guide prognosis.

Seven fundamental procedures for definitive correction of unilateral secondary cleft lip nasal deformity in soft tissue aspects.

It is accepted that patients who undergo appropriate primary repair for cleft lip will have secondary deformities. Because these deformities are caused by complex and diverse patterns, the deformities were categorized to provide a standardized treatment for each category. Pathologic characteristics of 1,170 patients were classified into 7 categories. Corrections were performed using 7 fundamental procedures corresponding to the surgical resolution of each deformity: 1) transposition of the caudal septum; 2) release of the septal-cartilaginous junction; 3) medial crus elevation; 4) lateral crus elevation; 5) release of the orbicularis oris muscle from the lip elevators; 6) anchoring of the orbicularis oris muscle to the anterior nasal spine; and 7) philtral column formation. A satisfaction survey was performed to evaluate the overall outcomes in 171 patients and an anthropometric analysis was performed in 38 patients. Satisfactory scores obtained through postoperative follow-up were higher than preoperative scores, and there was no difference between postoperative scores obtained over the short and long term. All preoperative anthropometric measurements were different from the postoperative measurements, indicating that the fundamental procedure achieved effective outcomes. These proposed 7 fundamental procedures can be used as guidelines that can always be applied for the correction of any secondary cleft lip nasal deformity to obtain ideal treatment outcomes.

Brain shift compromises the accuracy of neurosurgical image-guided interventions if not corrected by either intraoperative imaging or computational modeling. The latter requires intraoperative sparse measurements for constraining and driving model-based compensation strategies. Conoscopic holography, an interferometric technique that measures the distance of a laser light illuminated surface point from a fixed laser source, was recently proposed for non-contact surface data acquisition in image-guided surgery and is used here for validation of our modeling strategies. In this contribution, we use this inexpensive, hand-held conoscopic holography device for intraoperative validation of our computational modeling approach to correcting for brain shift. Laser range scan, instrument swabbing, and conoscopic holography data sets were collected from two patients undergoing brain tumor resection therapy at Vanderbilt University Medical Center. The results of our study indicate that conoscopic holography is a promising method for surface acquisition since it requires no contact with delicate tissues and can characterize the extents of structures within confined spaces. We demonstrate that for two clinical cases, the acquired conoprobe points align with our model-updated images better than the uncorrected images lending further evidence that computational modeling approaches improve the accuracy of image-guided surgical interventions in the presence of soft tissue deformations.

Although surgery for the treatment of hallux valgus is frequently performed, the exact rate of deep vein thrombosis following this procedure is unknown. We performed a single-center, prospective, phlebographically controlled study to quantify the rate of venous thrombosis following operative correction of hallux valgus. Consecutive patients undergoing chevron bunionectomy for correction of hallux valgus deformity were enrolled in the study. Patients with clinical or hematological risk factors for venous thrombosis were excluded. One hundred patients with a mean age of 48.9 years were operated on and did not receive medical prophylaxis against thrombosis. All patients were assessed with phlebography at a mean of twenty-nine days postoperatively. Venous thrombosis was found in four patients (4%). The mean age of these patients (and standard deviation) was 61.7 +/- 6.1 years compared with a mean age of 48.4 +/- 13.9 years for the patients in whom thrombosis did not develop (p = 0.034). Patients are at a low risk for venous thrombosis following surgical treatment of hallux valgus. The need for prophylaxis against thrombosis should be calculated individually for each patient according to his or her known level of risk. Routine medical prophylaxis against thrombosis might be justified for patients over the age of sixty years.

Background. The use of an external fixator for the purpose of distraction osteogenesis has been applied to a wide range of orthopedic problems caused by such diverse etiologies as congenital disease, metabolic conditions, infections, traumatic injuries, and congenital short stature. The purpose of this study was to analyze our experience of utilizing this method in patients undergoing a variety of orthopedic procedures of the femur. Methods. We retrospectively reviewed our experience of using external fixation for femoral reconstruction. Three subgroups were defined based on the primary reconstruction goal lengthening, deformity correction, and repair of nonunion/bone defect. Factors such as leg length discrepancy (LLD), limb alignment, and external fixation time and complications were evaluated for the entire group and the 3 subgroups. Results. There was substantial improvement in the overall LLD, femoral length discrepancy, and limb alignment as measured by mechanical axis deviation (MAD) and lateral distal femoral angle (LDFA) for the entire group as well as the subgroups. Conclusions. The Ilizarov external fixator allows for decreased surgical exposure and preservation of blood supply to bone, avoidance of bone grafting and internal fixation, and simultaneous lengthening and deformity correction, making it a very useful technique for femoral reconstruction.

2015-01-01

Craniocerebral gunshot injuries (CGI) are increasingly encountered by neurosurgeons in civilian and urban settings. Unfortunately this is a prevalent condition in developing countries, with major armed conflicts which is not very likely to achieve a high rate of prevention. Management goals should focus on early aggressive, vigorous resuscitation and correction of coagulopathy; those with stable vital signs undergo brain computed tomography scan. Neuroimaging is vital for surgical purposes, especially for determine type surgery, size and location of the approach, route of extraction of the foreign body; however not always surgical management is indicated, there is also the not uncommon decision to choose non-surgical management. The treatment consist of immediate life salvage, through control of persistent bleeding and cerebral decompression; prevention of infection, through extensive debridement of all contaminated, macerated or ischemic tissues; preservation of nervous tissue, through preventing meningocerebral scars; and restoration of anatomic structures through the hermetic seal of dura and scalp. There have been few recent studies involving penetrating craniocerebral injuries, and most studies have been restricted to small numbers of patients; classic studies in military and civil environment have identified that this is a highly lethal or devastating violent condition, able to leave marked consequences for the affected individual, the family and the health system itself. Various measures have been aimed to lower the incidence of CGI, especially in civilians. It is necessarily urgent to promote research in a neurocritical topic such as CGI, looking impact positively the quality of life for those who survive. PMID:27169063

To evaluate surgical outcomes (SOs) and visual outcomes (VOs) in cataract surgery comparing the Centurion ® phacoemulsification system (CPS) with the Infiniti ® phacoemulsification system (IPS). Prospective, consecutive study in a single-site private practice. Totally 412 patients undergoing cataract surgery with either the CPS using the 30-degree balanced ® tip ( n =207) or the IPS using the 30-degree Kelman ® tip ( n =205). Intraoperative and postoperative outcomes were documented prospectively up to one month follow-up. Nuclear sclerosis (NS) grade, cumulated dissipated energy (CDE), preoperative corrected distance visual acuity (CDVA), and CDVA at one month were recorded. CDE was 13.50% less in the whole CPS compared with the whole IPS subcohort. In eyes with NS grade III or greater, CDE was 28.87% less with CPS ( n =70) compared with IPS ( n =44) ( P =0.010). Surgical complications were not statistically different between the two subcohorts ( P =0.083), but in the one case of vitreous loss using the CPS, CDVA of 6/4 was achieved at one month. The mean CDVAs (VOs) at one month for NS grade III and above cataracts were -0.17 logMAR (6/4.5) in the CPS and -0.15 logMAR (6/4.5) in the IPS subcohort respectively ( P =0.033). CDE is 28.87% less, and VOs are significantly improved, in denser cataracts in the CPS compared with the IPS. The authors recommend the CPS for cases with denser nuclei.

A case report and a discussion of recent published data. To highlight the importance of vertebral hemangioma (VH) as a differential diagnosis in the evaluation of locally aggressive spinal lesions. VH commonly occur as incidental findings, however, locally aggressive VH have been described. Difficulties in diagnosing these lesions are well reported and relate to changes in fat content causing uncharacteristic appearances on imaging. The management options for these lesions include a combination of observation, embolization, sclerotherapy, surgical decompression, or stabilization and radiotherapy. A 45-year-old patient who was previously well presented with back pain and rapidly progressive paraparesis. Imaging confirmed the presence of an extensive lesion centered within the right T3 vertebral pedicle with intrusion into the spinal canal. Urgent surgical decompression was undertaken and was complicated by extensive intraoperative hemorrhage requiring massive transfusion. Histologically, the lesion was shown to be a cavernous VH with no evidence of malignancy. Following radiation oncology review, he was offered adjuvant radiotherapy to minimize the risks of recurrence. He achieved a near full neurologic recovery within 2 weeks and had a full recovery by 12 months. VH should be considered in the evaluation of locally aggressive spinal lesions. Angiography is a useful adjunct in the evaluation of these lesions, both as a diagnostic and therapeutic tool. After diagnosed correctly a wide range of treatment options exist that may prevent the patient from undergoing major surgical resection and reconstruction procedures, which may be associated with high rates of morbidity.

IMPORTANCE Follow-up with a primary care provider (PCP) in addition to the surgical team is routinely recommended to patients discharged after major surgery despite no clear evidence that it improves outcomes. OBJECTIVE To test whether PCP follow-up is associated with lower 30-day readmission rates after open thoracic aortic aneurysm (TAA) repair and ventral hernia repair (VHR), surgical procedures known to have a high and low risk of readmission, respectively. DESIGN, SETTING, AND PARTICIPANTS In a cohort of Medicare beneficiaries discharged to home after open TAA repair (n = 12 679) and VHR (n = 52 807) between 2003 to 2010, we compared 30-day readmission rates between patients seen and not seen by a PCP within 30 days of discharge and across tertiles of regional primary care use. We stratified our analysis by the presence of complications during the surgical (index) admission. MAIN OUTCOMES AND MEASURES Thirty-day readmission rate. RESULTS Overall, 2619 patients (20.6%) undergoing open TAA repair and 4927 patients (9.3%) undergoing VHR were readmitted within 30 days after surgery. Complications occurred in 4649 patients (36.6%) undergoing open TAA repair and 4528 patients (8.6%) undergoing VHR during their surgical admission. Early follow-up with a PCP significantly reduced the risk of readmission among open TAA patients who experienced perioperative complications, from 35.0% (without follow-up) to 20.4% (with follow-up) (P < .001). However, PCP follow-up made no significant difference in patients whose hospital course was uncomplicated (19.4% with follow-up vs 21.9% without follow-up; P = .31). In comparison, early follow-up with a PCP after VHR did not reduce the risk of readmission, regardless of complications. In adjusted regional analyses, undergoing open TAA repair in regions with high compared with low primary care use was associated with an 18% lower likelihood of 30-day readmission (odds ratio, 0.82; 95% CI, 0.71–0.96; P = .02), whereas no significant difference was found among patients after VHR. CONCLUSIONS AND RELEVANCE Follow-up with a PCP after high-risk surgery (eg, open TAA repair), especially among patients with complications, is associated with a lower risk of hospital readmission. Patients undergoing lower-risk surgery (eg, VHR) do not receive the same benefit from early PCP follow-up. Identifying high-risk surgical patients who will benefit from PCP integration during care transitions may offer a low-cost solution toward limiting readmissions. PMID:25074237

Supportive psychotherapy, in individual or group settings, may help improve surgical outcomes for women and girls living with female genital mutilation (FGM). To assess whether supportive psychotherapy given alongside surgical procedures to correct complications of FGM improves clinical outcomes. We searched major databases including CENTRAL, Medline, African Index Medicus, SCOPUS, PsycINFO, and others. There were no language restrictions. We checked the reference lists of retrieved studies for additional reports of relevant studies. We included studies of girls and women living with any type of FGM who received supportive psychotherapy or client education sessions alongside any surgical procedure to correct health complications from FGM. Two team members independently screened studies for eligibility. There were no eligible studies identified. There is no direct evidence for the benefits or harms of supportive psychotherapy alongside surgical procedures for women and girls living with FGM. Research evidence is urgently needed to guide clinical practice. 42015024639. © 2017 International Federation of Gynecology and Obstetrics.

Improvement in Creatinine Clearance after Open Heart Surgery in Infants as an Early Indicator of Surgical Success.

PubMed

Dagan, Amit; Dagan, Ovadia

2016-12-01

Early surgical correction of congenital heart malformations in neonates and small infants may be complicated by acute kidney injury (AKI), which is associated with higher morbidity and mortality rates, especially in patients who require dialysis. Glomerular filtration rate (GFR) is considered the best measurement of renal function which, in neonates and infants, is highly dependent on heart function. To determine whether measurements of creatinine clearance after open heart surgery in neonates and young infants can serve as an early indicator of surgical success or AKI. We conducted a prospective observational study in 19 neonates and small infants (body weight < 5 kg) scheduled for open heart surgery with cardiopulmonary bypass. Urine collection measurement of creatinine clearance and albumin excretion was performed before and during surgery and four times during 48 hours after surgery. Mean creatinine clearance was lowest during surgery (25.2 ± 4. ml/min/1.73 m2) and increased significantly in the first 16 hours post-surgery (45.7 ± 6.3 ml/min/1.73 m2). A similar pattern was noted for urine albumin which was highest during surgery (203 ± 31 µg/min) and lowest (93 ± 20 µg/min) 48 hours post-surgery. AKI occurred in four patients, and two patients even required dialysis. All six showed a decline in creatinine clearance and an increase in urine albumin between 8 and 16 hours post-surgery. In neonates and small infants undergoing open heart surgery, a significant improvement in creatinine clearance in the first 16 hours postoperatively is indicative of a good surgical outcome. This finding has important implications for the early evaluation and treatment of patients in the intensive care unit on the first day post-surgery.

To inquire into the reasons for family involvement in adult patients' surgical decision-making processes from the point of view of the patients' family. Making a patient the centre of medical decision-making is essential for respecting individual's autonomy. However, in a Chinese society, family members are often deeply involved in a patient's medical decision-making. Although family involvement has long been viewed as an aspect of the Chinese culture, empirical evidence of the reasons for family involvement in medical decision-making has been lacking. A qualitative study. In order to record and examine reasons for family involvement in adult patients' surgical decision-making, 12 different family members of 12 elective surgery patients were interviewed for collecting and analysing data. Three major reasons for family involvement emerged from the data analyses: (1) to share responsibility; (2) to ensure the correctness of medical information; and (3) to safeguard the patient's well-being. These findings also reveal that culture is not the only reason for family involvement. Making decision to undergo a surgery is a tough and stressful process for a patient. Family may provide the patient with timely psychological support to assist the patient to communicate with his or her physician(s) and other medical personnel to ensure their rights. It is also found that due to the imbalanced doctor-patient power relationship, a patient may be unable, unwilling to, or even dare not, tell the whole truth about his or her illness or feelings to the medical personnel. Thus, a patient would expect his or her family to undertake such a mission during the informed consent and decision-making processes. The results of this study may provide medical professionals with relevant insights into family involvement in adult patients' surgical decision-making. © 2016 John Wiley & Sons Ltd.

At present, limited experience exists on the treatment of atrial fibrillation (AF) in patients undergoing mitral valve repair (MVR) for Barlow disease. The aim of this investigation was to prospectively evaluate the radiofrequency ablation of AF in patients undergoing MVR for severe regurgitation due to Barlow disease. From January 1, 2007 to December 31, 2010, out of 85 consecutive patients with Barlow disease, 27 with AF underwent RF ablation associated with MVR. They were examined every 4 months in the first year after surgery and thereafter twice yearly. At follow-up, AF was observed in 4/25 (16.0%). NYHA (New York Heart Association) functional class improved significantly, with no patients in class III or IV (before surgery, 81.5% had been). Otherwise, among 58 patients in sinus rhythm, 6 (11%) developed AF during follow-up. No clinical or echocardiographic predictive factor was found in this subgroup. Results from our investigation suggest that radiofrequency ablation of AF in patients with Barlow disease undergoing MVR for severe regurgitation is effective and should be considered in every patient with Barlow disease and AF undergoing valve surgical repair.

Impact of airway morphological changes on pulmonary flows in scoliosis

2016-11-01

The relationship between thoracic deformity in scoliosis and lung function is poorly understood. In a pilot study, we reviewed computed tomography (CT) routine scans of patients undergoing scoliosis surgery. The CT scans were processed to segment the anatomy of the airways, lung and spine. A three-dimensional model was created to study the anatomical relationship. Preliminary analysis showed significant airway morphological differences depending on the anterior position of the spine. A computational fluid dynamics (CFD) study was also conducted on the airway geometry using the inspiratory scans. The CFD model assuming non-compliant airway walls was capable of showing pressure drops in areas of high airway resistance, but was unable to predict regional ventilation differences. Our results indicate a dependence between the dynamic deformation of the airway during breathing and lung function. Dynamic structural deformation must therefore be incorporated within any modelling approaches to guide clinicians on the decision to perform surgical correction of the scoliosis.

The purpose of this study was to evaluate surgically-induced astigmatism after spherical ablation in photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis (LASIK) for myopia with astigmatism < 1.00 D. The charts of patients undergoing spherical PRK or LASIK for the correction of myopia with minimal astigmatism of <1.00 D from 2002 to 2012 at the John A Moran Eye Center in Salt Lake City, UT, were retrospectively reviewed. Astigmatism was measured by manifest refraction. The final astigmatic refractive outcome at 6 months postoperatively was compared with the initial refraction by Alpins vector analysis. For PRK, average cylinder increased from 0.39 ± 0.25 (0.00-0.75) preoperatively to 0.55 ± 0.48 (0.00-1.75) postoperatively (P = 0.014), compared with an increase in LASIK eyes from 0.40 ± 0.27 (0.00-0.75) preoperatively to 0.52 ± 0.45 (0.00-2.00) postoperatively (P = 0.041). PRK eyes experienced an absolute value change in cylinder of 0.41 ± 0.32 (0.00-1.50) and LASIK eyes experienced a change of 0.41 ± 0.31 (0.00-1.50, P = 0.955). Mean surgically-induced astigmatism was 0.59 ± 0.35 (0.00-1.70) in PRK eyes, with an increase in surgically-induced astigmatism of 0.44 D for each additional 1.00 D of preoperative cylinder; in LASIK eyes, mean surgically-induced astigmatism was 0.55 ± 0.32 (0.00-1.80, P = 0.482), with an increase in surgically-induced astigmatism of 0.29 D for each 1.00 D of preoperative cylinder. Spherical ablation can induce substantial astigmatism even in eyes with less than one diopter of preoperative astigmatism in both PRK and LASIK. No significant difference in the magnitude of surgically-induced astigmatism was found between eyes treated with PRK and LASIK, although surgically-induced astigmatism was found to increase with greater levels of preoperative astigmatism in both PRK and LASIK.

To determine the cost effectiveness of breast biopsy by 9G vacuum-assisted guided by vertical stereotaxy or ultrasonography in comparison with breast biopsy by 14G core-needle biopsy and surgical biopsy. We analyzed a total of 997 biopsies (181 vacuum-assisted, 626 core, and 190 surgical biopsies). We calculated the total costs (indirect and direct) of the three types of biopsy. We did not calculate intangible costs. We measured the percentage of correct diagnoses obtained with each technique. To identify the most cost-effective option, we calculated the mean ratios for the three types of biopsies. Total costs were €225.09 for core biopsy, €638.90 for vacuum-assisted biopsy, and €1780.01 for surgical biopsy. The overall percentage of correct diagnoses was 91.81% for core biopsy, 94.03% for vacuum-assisted biopsy, and 100% for surgical biopsy; however, these differences did not reach statistical significance (p=0.3485). For microcalcifications, the percentage of correct diagnoses was 50% for core biopsy and 96.77% for vacuum-assisted biopsy (p<0.0001). For nodules, there were no significant differences among techniques. The mean cost-effectiveness ratio considering all lesions was 2.45 for core biopsy, 6.79 for vacuum-assisted biopsy, and 17.80 for surgical biopsy. Core biopsy was the dominant option for the diagnosis of suspicious breast lesions in general. However, in cases with microcalcifications, the low percentage of correct diagnoses achieved by core biopsy (50%) advises against its use in this context, where vacuum-assisted biopsy would be the technique of choice because it is more cost-effective than surgical biopsy, the other technique indicated for biopsying microcalcifications.

This study was undertaken to compare the clinical results of traditional surgery and a percutaneous procedure for secundum type atrial septal defect (ASD) combined with pulmonary valve stenosis (PS). A total of 78 consecutive patients were identified between March 2004 and July 2012 in our institution. Thirty-five patients (44.9%) underwent percutaneous correction and the remaining 43 patients (55.1%) were treated surgically. All patients had simultaneous complete correction in both groups and no serious complications occurred. The surgical group was significantly younger (13.9 ± 13.0 versus 31.0 ± 17.5 years, P < 0.001) and had a longer mean hospital stay (12.6 ± 4.7 versus 5.3 ± 1.5 days, P < 0.001). There were no significant differences in defect size (18.0 ± 7.9 versus 16.9 ± 8.4 mm, P = 0.553) and transvalvular gradient detected by transthoracic echocardiography (TTE) (74.7 ± 28.3 versus 87.6 ± 37.8 mmHg, P = 0.089) between the two groups. Significant tricuspid regurgitation (TR) decreased from 66% to 14% in the transcatheter group and from 40% to 9% in the surgical group. Mild pulmonary regurgitation was detected in 8 patients in the transcatheter cohort and in 6 patients in the surgical cohort after the procedure. At last follow-up, 83% and 93% of the patients in the transcatheter and surgical groups, respectively, were free of any symptoms, and a significant improvement from preprocedure was observed in the transcatheter group but not in the surgical group (P = 0.005 and P = 0.062). In conclusion, transcatheter correction is a valuable alternative to surgery and allows more patients to be effectively treated in China.

To examine the outcomes of blunt hepatic trauma, and compare surgical and non-surgical treatment in patients admitted with hemodynamic stability and with no obvious indications of laparotomy. This is a retrospective study of cases admitted to a university teaching hospital between the years 2000 and 2010. Patients undergoing surgical treatment were divided into two groups: (a) all patients undergoing surgical treatment, and (b) patients with obvious need for surgery. In this period, 120 patients were admitted with blunt hepatic trauma. Sixty five patients (54.1%) were treated non-operatively and fifty five patients were operated upon. Patients treated non-operatively had better physiologic conditions on admission, demonstrated less severe injuries (except the grade of hepatic injury), received less blood components and had lower morbidity and mortality than the patients operated upon. Patients who underwent non-operative treatment had a lower need for blood transfusion but higher rates of complications and mortality than the patients operated upon. Patients who were operated upon, with no obvious indications for surgery, had higher rates of complication and mortality than patients not operated upon. A non-operative approach resulted in lower complications, a lower need for blood transfusions and lower mortality.

Wound dehiscence and surgical site infections (SSIs) can have a profound impact on patients as they often require hospital readmission, additional surgical interventions, lengthy intravenous antibiotic administration, and delayed rehabilitation. Negative pressure wound therapy (NPWT) exposes the wound site to negative pressure, resulting in the improvement of blood supply, removal of excess fluid, and stimulation of cellular proliferation of granulation tissue. To assess the incidence of wound infection and dehiscence in patients undergoing long-segment thoracolumbar fusion before and after the routine use of NPWT. Retrospective study. One hundred sixty patients undergoing long-segment thoracolumbar spine fusions were included in this study. Postoperative incidence of wound infection and dehiscence. All adult patients undergoing thoracolumbar fusion for spinal deformity over a 6-year period at Duke University Medical Center by the senior author (CB) were included in this study. In 2012, a categorical change was made by the senior author (CB) that included the postoperative routine use of incisional NPWT devices after primary wound closure in all long-segment spine fusions. Before 2012, NPWT was not used. After primary wound closure, a negative pressure device is contoured to the size of the incision and placed over the incision site for 3 postoperative days. We retrospectively review the first 46 cases in which NPWT was used and compared them with the immediately preceding 114 cases to assess the incidence of wound infection and dehiscence. One hundred sixty (NPWT: 46 cases, non-NPWT: 114 cases) long-segment thoracolumbar spine fusions were performed for deformity correction. Baseline characteristics were similar between both cohorts. Compared with the non-NPWT cohort, a 50% decrease in the incidence of wound dehiscence was observed in the NPWT patient cohort (6.38% vs. 12.28%, p=.02). Similarly, compared with the non-NPWT cohort, the incidence of postoperative SSIs was significantly decreased in the NPWT cohort (10.63% vs. 14.91%, p=.04). Routine use of incisional NPWT was associated with a significant reduction in the incidence of postoperative wound infection and dehiscence. Copyright © 2014 Elsevier Inc. All rights reserved.

Surgical complications contribute substantially to costs. Most important, surgical complications contribute to morbidity and mortality, and some may be preventable. This study estimates costs of specific surgical complications for patients undergoing general surgery in VA hospitals using merged data from the VA Surgical Quality Improvement Program and VA Decision Support System. Costs associated with 19 potentially preventable complications within 6 broader categories were estimated using generalized, linear mixed regression models to control for patient-level determinants of costs (eg, type of operation, demographics, comorbidity, severity) and hospital-level variation in costs. Costs included costs of the index hospitalization and subsequent 30-day readmissions. In 14,639 patients undergoing general surgical procedures from 10/2005 through 9/2006, 20% of patients developed postoperative surgical complications. The presence of any complication significantly increased unadjusted costs nearly 3-fold ($61,083 vs $22,000), with the largest cost differential attributed to respiratory complications. Patients who developed complications had several markers for greater preoperative severity, including increased age and a lesser presurgery functional health status. After controlling for differences in patient severity, costs for patients with any complication were 1.89 times greater compared to costs for patients with no complications (P < .0001). Within major complication categories, adjusted costs were significantly greater for patients with respiratory, cardiac, central nervous system, urinary, wound, or other complications. Surgical complications contribute markedly to costs of inpatient operations. Investment in quality improvement that decreases the incidence of surgical complications could decrease costs.

2009-10-01

A 52-year-old patient, ASA physical status IV, undergoing a radical prostatectomy for cancer with a robotic system had a cardiac arrest 3 hours into the case. All attempts to resuscitate were unsuccessful, and several hours later he was pronounced dead. Underlying patient comorbidity and procedural issues contributed to the patient's death. The patient had a history of coronary artery disease that required the placement of drug-eluting stents 2 years before this surgical procedure. The preoperative cardiac evaluation and pharmacological management of patients with drug-eluting coronary stents are reviewed. There are a number of positional and technical considerations for patients undergoing robotic surgical procedures, especially in relation to the requirement of low-lithotomy and steep Trendelenburg positions. The cardiac and respiratory systems are especially vulnerable to the extreme and lengthy head-down position. The needed positioning, combined with the problems associated with insufflation, presents a unique challenge in anesthetic management. This course reviews the current literature on the surgical implications for patients with drug-eluting stents and the physiologic factors related to position and pneumoperitoneum and their associated stressors. By using a review of the contemporary literature, a best-evidence approach to anesthetic management is reviewed.

Relationship Between Preoperative Anemia and In-Hospital Mortality in Children Undergoing Noncardiac Surgery.

The relationship between preoperative anemia and in-hospital mortality has not been investigated in the pediatric surgical population. We hypothesized that children with preoperative anemia undergoing noncardiac surgery may have an increased risk of in-hospital mortality. We identified all children between 1 and 18 years of age with a recorded preoperative hematocrit (HCT) in the 2012, 2013, and 2014 American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) pediatric databases. The endpoint was defined as the incidence of in-hospital mortality. Children with preoperative anemia were identified based on their preoperative HCT. Demographic and surgical characteristics, as well as comorbidities, were considered potential confounding variables in a multivariable logistic regression analysis. A sensitivity analysis was performed using propensity-matched analysis. Among the 183,833 children included in the 2012, 2013, and 2014 ACS NSQIP database, 74,508 had a preoperative HCT recorded (41%). After exclusion of all children <1 year of age (n = 12,063), those with congenital heart disease (n = 8943), and those who received a preoperative red blood cell (RBC) transfusion (n = 1880), 12,551 (24%) children were anemic, and 39,071 (76%) were nonanemic. The median preoperative HCT was 33% (interquartile range, 31-35) in anemic children, and 39% (interquartile range, 37-42) in nonanemic children (P < .001). Using multivariable logistic regression analysis, and after adjustment for RBC transfusion (OR, 2.13; 95% CI, 1.39-3.26; P < .001), we observed that preoperative anemia was associated with higher odds for in-hospital mortality (OR, 2.17; 95% CI, 1.48-3.19; P < .001). After propensity matching, the presence of anemia was also associated with higher odds of in-hospital mortality (OR, 1.75; 95% CI, 1.15-2.65; P = .004). Our study demonstrates that children with preoperative anemia are at increased risk for in-hospital mortality. Further studies are needed to assess whether the correction of preoperative HCT, through the development of a patient blood management program, improves patient outcomes or simply reduces the need for transfusions.

Surgical correction of scoliosis in children with spastic quadriplegia: benefits, adverse effects, and patient selection.

Cerebral palsy (CP) is a group of nonprogressive syndromes of posture and motor impairment associated with lesions of the immature brain. Spastic quadriplegia is the most severe form with a high incidence of scoliosis, back pain, respiratory compromise, pelvic obliquity, and poor sitting balance. Surgical stabilization of the spine is an effective technique for correcting deformity and restoring sitting posture. The decision to operate in this group of patients is challenging. The aim of this study is to determine the benefits of surgical correction of scoliosis in children with spastic quadriplegia, the adverse effects of this treatment, and what preoperative factors affect patient outcome after surgical correction. A systematic review was undertaken to identify studies describing benefits and adverse effects of surgery in spastic quadriplegia. Factors affecting patient outcome following surgical correction of scoliosis were assessed. Studies involving adults and nonspastic quadriplegia were excluded. A total of 10 case series and 1 prospective and 3 retrospective cohort studies met inclusion criteria. There was significant variation in the overall risk of complications (range, 10.9-70.9%), mortality (range, 2.8-19%), respiratory/pulmonary complications (range, 26.9-57.1%), and infection (range, 2.5-56.8%). Factors associated with a worse outcome were a significant degree of thoracic kyphosis, days in the intensive care unit, and poor nutritional status. Caregivers report a high degree of satisfaction with scoliosis surgery for children with spastic quadriplegia. There is limited evidence of preoperative factors that can predict patient outcome after scoliosis. There is a need for well-designed prospective studies of scoliosis surgery in spastic quadriplegia.

A surgical procedure is described which corrects the ansiform ear by repositioning and reconstructing the anthelix and the anterior crus with the formation of the triangular fossa. This corrects the scaphoconchal angle and improves the cephaloauricular angle, overcoming the problem of prominent ears. Correction in early childhood is recommended in order to avoid personality problems that may result from the deformity, particularly in boys. The technique employed yields important advantages: (1) prolonged use of the helmet-type of surgical dressing is unnecessary; (2) scars are less conspicuous; (3) the outcome is attractive and normal; (4) bleeding and inflammatory complications are avoided; and (5) recurrence of the malformation is unlikely.

Creating an aesthetically appealing result using thoracoplasty, especially when correcting extensive deformities, but only causing low morbidity, is challenging. The frequency of thoracoplasties in cases of pectus carinatum (PC) has increased due to improved experience and modified surgical techniques, resulting in low morbidity and low complication rates. The indications for surgical treatment are still controversial and, in most cases, remain aesthetic or psychological rather than physiological. However, whether cardiopulmonary function changes after surgical repair remains a matter of controversy. We sought to investigate and shed light on published knowledge regarding this question. We searched MEDLINE and PubMed databases, using various defined search phrases and inclusion criteria, to identify articles on pre- and postoperative cardiopulmonary evaluation and outcomes. Six studies met the inclusion criteria: 5 studies evaluated patients with PC for cardiopulmonary outcomes after chest wall surgery and 1 did so following conservative compression treatment. In these studies, surgical and conservative correction of PC did not reduce absolute lung volumes and spirometric measurements and consequently had no pathogenic effect on cardiopulmonary function. The results of this systematic review suggest that surgical correction of PC has no symptomatic pathogenic effect on cardiopulmonary function. The results, however, revealed both heterogeneity in the examinations used and inconsistent methods within each study. Further prospective trials with a stronger methodological design are necessary to objectively confirm that surgical correction of PC does not impair cardiopulmonary function. © The Author 2017.

Introduction Morquio A syndrome is characterized by a unique skeletal dysplasia, leading to short neck and trunk, pectus carinatum, laxity of joints, kyphoscoliosis, and tracheal obstruction. Cervical spinal cord compression/inability, a restrictive and obstructive airway, and/or bone deformity and imbalance of growth, are life-threatening to Morquio A patients, leading to a high morbidity and mortality. It is critical to review the current therapeutic approaches with respect to their efficacy and limitations. Areas covered Patients with progressive skeletal dysplasia often need to undergo orthopedic surgical interventions in the first two decades of life. Recently, we have treated four patients with a new surgery to correct progressive tracheal obstruction. Enzyme replacement therapy (ERT) has been approved clinically. Cell-based therapies such as hematopoietic stem cell therapy (HSCT) and gene therapy are typically one-time, permanent treatments for enzyme deficiencies. We report here on four Morquio A patients treated with HSCT approved in Japan and followed for at least ten years after treatment. Gene therapy is under investigation on mouse models but not yet available as a therapeutic option. Expert opinion ERT and HSCT in combination with surgical intervention(s) are a therapeutic option for Morquio A; however, the approach for bone and cartilage lesion remains an unmet challenge.

To determine whether procedure-specific brochures improve patients' pre-operative knowledge, to determine the amount of information expected by patients during the consenting process, and to determine whether the recently proposed 'Request for Treatment' consenting process is viable on a large scale. A prospective, questionnaire-based study of 100 patients admitted for selected, elective surgical procedures. In total, 99 per cent of patients were satisfied with the information received in the out-patient department, regarding the proposed procedure. However, 38 per cent were unable to correctly state the nature of the surgery or specific procedure they were scheduled to undergo. Although the vast majority of patients were able to state the intended benefits to be gained from the procedure, only 54 per cent were able to list at least one potential complication, and 80 per cent indicated that they wished to be informed about all potential complications, even if these occurred in less than 1 per cent of cases. The introduction of procedure-specific brochures improved patients' pre-operative knowledge. Although the failings of current consenting practice are clear, the Request for Treatment consenting process would not appear to be a viable alternative because of the large number of patients unable to accurately recall the nature of the proposed surgery or potential complications, following consent counselling.

Despite the marked decline in mortality of acute appendicitis over the past 50 years, the rate of perforation and negative appendectomy remains unchanged. The most effective means of controlling human suffering and economic cost associated with appendicitis is the identification and correction of factors responsible for perforation. Negative appendectomy rates have been relatively stable over the decades. Progress in diagnosis and diagnostic imaging still has not provided a foolproof non-invasive test to rule out the presence of appendicitis accurately. Clinical assessment determines the treatment and the clinical observation should be done by the surgeon. The use of H2-receptor antagonists has not reduced emergency admission of patients with duodenal ulcer. Mortality associated with perforated peptic ulcer remains high in spite of advances in surgical management. The patients with acute obstructed cholecystitis usually reach the surgeon with more advanced stage of the disease which results in increased morbidity and subsequently increased cost for undergoing cholecystectomy. If the patient develops severe diffuse peritonitis, the mortality could reach 30%. This is in spite of aggressive surgical treatment, potent antibiotics, modern intensive care and diagnostic procedures. To improve the results, more advanced treatment to avoid the development of peritonitis and more effective antibiotics to control the inflammation will be needed.

Incidence and Management of De Novo Lower Urinary Tract Symptoms After Pelvic Organ Prolapse Repair.

PubMed

Tran, Henry; Chung, Doreen E

2017-09-12

Pelvic organ prolapse (POP) is a significant problem with many options for surgical correction. Following prolapse surgery, de novo lower urinary tract symptoms (LUTS) are not uncommon. We review the current literature on de novo lower urinary tract symptoms following POP repair and discuss the role of urodynamics in the evaluation of the prolapse patient. Patients with occult stress urinary incontinence (SUI) appear to be at higher risk of developing de novo SUI after POP repair. Prolapse reduction in patients undergoing urodynamic evaluation is important. Different types of POP repair influence rates of de novo SUI. Also, prophylactic anti-incontinence procedures at time of POP repair appear to lower the incidence of de novo SUI, but at the cost of increased risk of complications and morbidity. Pre-existing overactive bladder (OAB) symptoms may either improve or persist, and de novo OAB can develop. The specific role of urodynamic study testing for POP is still being determined. Increasingly, women are seeking surgical treatment for POP. Aside from complications related to surgery in general, proper patient counseling is important regarding the risk of development of de novo voiding problems following surgery. Despite a growing body of literature looking at de novo voiding symptoms after prolapse repair, more studies are still needed.

Data on the quality of communication during informed consent for surgery is sparse; we investigated this issue in a cohort of patients undergoing laparoscopic cholecystectomy (LC). Two hundred and seven consecutive patients with benign biliary disease who had undergone LC completed 2 questionnaires. We investigated the patient choice to undergo the surgical procedure along with perceptions of risk complications presented by the surgeon. Nineteen attending surgeons also completed a questionnaire giving information on their recall perception on the information they provided. Multiple logistic regression analyses determined the predictors of perceived communication factors during the informed consent process. One hundred eighty-one patients (87.4%) returned questionnaires. Younger patients (<50 y) with lower education perceived higher level of risk complications compared with older and higher educated patients (P=0.04 and P<0.001). Younger patients felt psychologic support was necessary (P<0.001) and that quality of life issues related to the interventions were under addressed (P=0.018). Differences were observed between patients' recalled risk of complications and the risk to convert LC to open laparotomy and physicians' perception of information provided to patients regarding these aspects (P<0.01). Although informed consent for surgical procedures requires that the procedures are explained and that the patient understands the procedures and risks, our data suggest different perceptions of the quality of information provided during this process between patients and physicians. Physicians should be aware that surgical risks might be perceived differently by patients and this perception might be influenced, for example, by patients' age and education. Major efforts should be directed to improve communications skills in surgical laparoscopy.

A plethora of papers have been written regarding postcatheterization femoral pseudoaneurysms. However, literature is lacking on pseudoaneurysmal management in patients undergoing coronary artery bypass grafting (CABG). Thus, we examined if pseudoaneurysms with subsequent CABG can be managed with the same strategies as those not exposed to the intense anticoagulation accompanying CABGs. During a 14-year study period, we retrospectively examined femoral iatrogenic pseudoaneurysms (IPSAs) diagnosed postheart catheterization in patients having a subsequent CABG. Patient information was obtained from electronic medical records and included pseudoaneurysm characteristics, treatment, and resolution. Outcomes of interest included the occurrence of IPSA treatment failures and complications. In the 66 patients (mean age, 66 ± 11 years, 46% male) meeting inclusion criteria, mean dose of heparin received during the CABG procedure was 34 000 ± 23 000 units. The IPSA size distribution was the following: 17% of IPSAs measured <1 cm, 55% between 1 and 3 cm, and 21% measured >3 cm. Pseudoaneurysms were managed with compression, duplex-guided thrombin injection, and surgical repair (1%, 27%, and 26% of cases, respectively). Thrombin injection and surgical repair were 100% effective at treating pseudoaneurysms, with 1 patient experiencing a surgical site infection postsurgical repair. Observation-only management was employed in 30 (45%) patients. Nine of 30 patients with no intervention beyond observation had duplex documented resolution/thrombosis during follow-up. One patient initially managed by observation required readmission and surgical repair of an enlarging pseudoaneurysm (6 cm growth) following CABG. Management of pseudoaneurysms in patients prior to CABG should be similar to those patients not undergoing intense anticoagulation. In appropriate cases, small aneurysms can be safely observed, while thrombin injections are effective and safe as well. Thus, routine open surgical repair is not routinely required in patients with femoral pseudoaneurysms at time of CABG. © The Author(s) 2016.

Patient expectations for surgery: are they being met?

The purpose of the study was to determine patient expectations for the outcomes of three elective surgical procedures, the extent to which patient expectations for surgery were met, the reasons for unmet expectations, and the factors that might predict unmet expectations. Better understanding of these questions might help identify targeted interventions to better prepare patients for specific health care experiences. In a longitudinal, prospective design, a convenience sample of 445 patients (age range, 18 to 86 years) at a general surgery clinic at a major academic medical center was included--177 patients undergoing inguinal hernia repair, 146 undergoing parathyroidectomy, and 122 undergoing cholecystectomy. Patients completed both standardized and newly developed condition-specific health survey instruments. Preoperative interviews were administered, followed by mailed surveys 2 months after surgery. Between 9% and 27% of the respondents reported unmet expectations, with significant variation by condition; reasons included perceived lack of symptom relief, surgical complications, and process of care issues. Patients undergoing parathyroidectomy had a greater probability of unmet expectations. Both feeling prepared for surgery and improved postoperative symptom relief and role functioning reduced the probability of unmet expectations. To reduce the level of unmet expectations, patients need to be prepared both for the surgical experience and for what to expect in the recovery phase. This is especially true for complex illnesses such as primary hyperparathyroidism. Innovative educational strategies to ensure adequate preparation for surgery will be needed, and attention will need to be paid to latent, unstated process measures, if unmet expectations are to be reduced.

Data-assessing trends and perioperative outcomes relative to surgical approach for colorectal cancer (CRC) surgery are lacking. We report national trends of CRC surgery and compare postoperative outcomes by surgical approach. A total of 261,886 patients undergoing surgery for CRC were identified using the Nationwide Inpatient Sample from 2009 to 2012. Trends in surgical approach were assessed using the Cochrane-Armitage test of trends. Multivariable logistic and linear regression analyses were performed to compare length of stay (LOS), postoperative complications, and cost by surgical approach. At the time of surgery, 57.5% underwent an open procedure, whereas 42.4% underwent either a laparoscopic (39.9%) or robotic (2.5%) colorectal surgery. The use of minimally invasive surgery increased over time (2009 versus 2012: 37.3% versus 46.8%; P < 0.001). Postoperative morbidity was 15.9% and was higher after open surgery (open versus laparoscopic versus robotic: 18.4% versus 12.4% versus 13.3%; P < 0.001). Patients who underwent a minimally invasive surgery had shorter LOS (laparoscopic: OR, 0.55, 95% CI, 0.52-0.58; robotic: OR, 0.58; 95% CI, 0.49-0.69; both P < 0.001). Robotic surgery was consistently associated with the highest mean costs followed by laparoscopic and open surgery (P < 0.001). Patients undergoing minimally invasive colorectal surgery had a lower postoperative morbidity and shorter LOS compared with patients undergoing open colorectal surgery. Copyright © 2016 Elsevier Inc.

The risk of respiratory conditions, such as inflammatory airway disease (IAD) and exercise-induced pulmonary haemorrhage (EIPH), are thought to be higher in racehorses that undergo prosthetic laryngoplasty with ventriculocordectomy (PLVC) surgery to treat left-sided laryngeal hemiplegia (LLH) than in racehorses with normal laryngeal function. However, this has not been investigated formally owing to the difficulty of obtaining reliable follow-up data. To determine the incidence of respiratory conditions (IAD and EIPH), duration of racing career, number of starts and number of starts for which stakes money was earned in racehorses that had undergone PLVC surgery to treat LLH, compared with racehorses that did not have LLH or undergo any laryngeal surgery. A retrospective cohort study design was used, with surgical, clinical and race data of Thoroughbred racehorses obtained from the time of importation until retirement. The surgical cohort consisted of racehorses that had undergone PLVC for LLH and met specific inclusion criteria. Every surgical case was matched, according to trainer, year of import into Hong Kong and pre-import international handicap rating, to 2 unexposed racehorses. Respiratory conditions, such as excessive tracheal mucus and epistaxis due to severe EIPH, were significantly increased in the surgical cohort, compared with the matched unexposed cohort (P values <0.001 and <0.004, respectively). Racing career duration in the surgical cohort was significantly shorter than in the unexposed cohort, which was primarily due to retirement because of epistaxis. The number of race starts was fewer in the surgical than in the unexposed cohort after surgery/matching, but the number of starts for which stakes money was earned was not significantly different. Owners and trainers should be advised that racehorses with LLH that undergo PLVC surgery are at an increased risk of respiratory conditions (IAD and severe EIPH), which is likely to shorten their racing career compared to racehorses with normal laryngeal function. Racing performance in terms of race starts was significantly less in racehorses that had undergone PLVC surgery; however, the number of starts for which stakes money was earned was similar to those racehorses that were unexposed. © 2012 EVJ Ltd.

Surgically assisted rapid maxillary expansion (SARME) is usually considered the gold standard for maxillary transverse expansion in adults. However, a second surgical procedure is needed in cases of associated sagittal or vertical discrepancies. We describe the use of two new innovative devices for the correction of discrepancies in all dimensions during a single surgical procedure, thus reducing treatment duration. We report the case of a 21-year-old female patient, referred to our department for skeletal Class III malocclusion associated with right-side laterognathism and transverse maxillary deficiency. The patient underwent one-stage surgery, using sliding osteosynthesis plates and an adjustable bone-borne distractor. Pre-surgical orthodontics consisted in leveling and aligning the mandibular arch; maxillary leveling was initiated 3 months before surgery. Postoperative palatal distraction combined with orthodontic finishing enabled complete correction of dental and bony discrepancies after 3 months. In our experience, treatment of transverse, sagittal and vertical discrepancies has been possible in a single surgical procedure, using two innovative techniques: sliding osteosynthesis and an adjustable bone distractor. Two years post-surgery, the correction is stable in all dimensions. Copyright © 2015. Published by Elsevier Masson SAS.

Prevention of Surgical Fires: A Certification Course for Healthcare Providers.

Fisher, Marquessa

2015-08-01

An estimated 550 to 650 surgical fires occur annually in the United States. Surgical fires may have severe consequences, including burns, disfigurement, long-term medical care, or death. This article introduces a potential certification program for the prevention of surgical fires. A pilot study was conducted with a convenience sample of 10 anesthesia providers who participated in the education module. The overall objective was to educate surgical team members and to prepare them to become certified in surgical fire prevention. On completion of the education module, participants completed the 50-question certification examination. The mean pretest score was 66%; none of the participants had enough correct responses (85%) to be considered competent in surgical fire prevention. The mean post- test score was 92.80%, with all participants answering at least 85% of questions correct. A paired-samples t test showed a statistically significant increase in knowledge: t (df = 9) = 11.40; P = .001. Results of the pilot study indicate that this course can remediate gaps in knowledge of surgical fire prevention for providers. Their poor performance on the pretest suggests that many providers may not receive sufficient instruction in surgical fire prevention.

Surgical myotomy of the lower esophageal sphincter has a 5-year success rate of approximately 91 %. Peroral endoscopic myotomy can provide similar results for controlling dysphagia. Some patients experience either persistent or recurrent dysphagia after myotomy. We present here a retrospective analysis of our experience with redo myotomy for recurrent dysphagia in patients with achalasia. From March 1996 to February 2015, 234 myotomies for primary or recurrent achalasia were performed in our center. Fifteen patients (6.4 %) had had a previous myotomy and were undergoing surgical redo myotomy (n = 9) or endoscopic redo myotomy (n = 6) for recurrent symptoms. Patients presented at a median of 10.4 months after previous myotomy. Median preoperative Eckardt score was 6. Among the nine patients undergoing surgical myotomy, three esophageal perforations occurred intraoperatively (all repaired immediately). Surgery lasted 111 and 62 min on average (median) in the surgical and peroral endoscopic myotomy (POEM) groups, respectively. No postoperative complications occurred in either group. Median postoperative stay was 3 and 2.5 days in the surgical and POEM groups, respectively. In the surgical group, Eckardt score was <3 for seven out of nine patients after a mean follow-up of 19 months; it was <3 for all six patients in the POEM group after a mean follow-up of 5 months. A redo myotomy should be considered in patients who underwent myotomy for achalasia and presenting with recurrent dysphagia. Preliminary results using POEM indicate that the technique can be safely used in patients who have undergone previous surgical myotomy.

Severe obesity in adolescence is associated with reduced life expectancy and impaired quality of life. Long-term benefits of conservative treatments in adolescents are known to be modest, whereas short-term outcomes of adolescent bariatric surgery are promising. We aimed to compare 5-year outcomes of adolescent surgical patients after Roux-en-Y gastric bypass with those of conservatively treated adolescents and of adults undergoing Roux-en-Y gastric bypass, in the Adolescent Morbid Obesity Surgery (AMOS) study. We did a nationwide, prospective, non-randomised controlled study of adolescents (aged 13-18 years) with severe obesity undergoing Roux-en-Y gastric bypass at three specialised paediatric obesity treatment centres in Sweden. We compared clinical outcomes in adolescent surgical patients with those of matched adolescent controls undergoing conservative treatment and of adult controls undergoing Roux-en-Y gastric bypass. The primary outcome measure was change in BMI over 5 years. We used multilevel mixed-effect regression models to assess longitudinal changes. This trial is registered with ClinicalTrials.gov, number NCT00289705. Between April, 2006, and May, 2009, 100 adolescents were recruited to the study, of whom 81 underwent Roux-en-Y gastric bypass (mean age 16·5 years [SD 1·2], bodyweight 132·8 kg [22·1], and BMI 45·5 kg/m 2 [SD 6·1]). 80 matched adolescent controls and 81 matched adult controls were enrolled for comparison of outcomes. The change in bodyweight in adolescent surgical patients over 5 years was -36·8 kg (95% CI -40·9 to -32·8), resulting in a reduction in BMI of -13·1 kg/m 2 (95% CI -14·5 to -11·8), although weight loss less than 10% occurred in nine (11%). Mean BMI rose in adolescent controls (3·3 kg/m 2 , 95% CI 1·1-4·8) over the 5-year study period, whereas the BMI change in adult controls was similar to that in adolescent surgical patients (mean change -12·3 kg/m 2 , 95% CI -13·7 to -10·9). Comorbidities and cardiovascular risk factors in adolescent surgical patients showed improvement over 5 years and compared favourably with those in adolescent controls. 20 (25%) of 81 adolescent surgical patients underwent additional abdominal surgery for complications of surgery or rapid weight loss and 58 (72%) showed some type of nutritional deficiency; health-care consumption (hospital attendances and admissions) was higher in adolescent surgical patients compared with adolescent controls. 20 (25%) of 81 adolescent controls underwent bariatric surgery during the 5-year follow-up. Adolescents with severe obesity undergoing Roux-en-Y gastric bypass had substantial weight loss over 5 years, alongside improvements in comorbidities and risk factors. However, gastric bypass was associated with additional surgical interventions and nutritional deficiencies. Conventional non-surgical treatment was associated with weight gain and a quarter of patients had bariatric surgery within 5 years.

The management of Type III acromioclavicular (AC) dislocations is still controversial. We wished to compare the rate of recurrence and outcome scores of operative versus non-operative treatment of patients with Type III AC dislocations. A systematic review of the literature was performed by applying the PRISMA guidelines according to the PRISMA checklist and algorithm. A search in Medline, PubMed, Cochrane and CINAHL was performed using combinations of the following keywords: 'dislocation', 'Rockwood', 'type three', 'treatment', 'acromioclavicular' and 'joint'. Fourteen studies were included, evaluating 646 shoulders. The rate of recurrence in the surgical group was 14%. No statistical significant differences were found between conservative and surgical approaches in terms of postoperative osteoarthritis and persistence of pain, although persistence of pain seemed to occur less frequently in patients undergoing a surgical treatment. Persistence of pain seemed to occur less frequently in patients undergoing surgery. Persistence of pain seems to occur less frequently in patients treated surgically for a Type III AC dislocation. There is insufficient evidence to establish the effects of surgical versus conservative treatment on functional outcome of patients with AC dislocation. High-quality randomized controlled clinical trials are needed to establish whether there is a difference in functional outcome. © The Author 2017. Published by Oxford University Press.

In decades of technical developments after the first surgical corrections of spinal deformities, the set of devices, techniques, and tools available to the surgeons has widened dramatically. Nevertheless, the rate of complications due to mechanical failure of the fixation or the instrumentation remains rather high. Indeed, basic and clinical research about the principles of deformity correction and the optimal surgical strategies (i.e., the choice of the fusion length, the most appropriate instrumentation, and the degree of tolerable correction) did not progress as much as the implantable devices and the surgical techniques. In this work, a software approach for the biomechanical simulation of the correction of patient-specific spinal deformities aimed to the identification of its biomechanical principles is presented. The method is based on three-dimensional reconstructions of the spinal anatomy obtained from biplanar radiographic images. A user-friendly graphical user interface allows for the planning of the desired deformity correction and to simulate the implantation of pedicle screws. Robust meshing of the instrumented spine is provided by using consolidated computational geometry and meshing libraries. Based on a finite element simulation, the program is able to predict the loads and stresses acting in the instrumentation as well as those in the biological tissues. A simple test case (reduction of a low-grade spondylolisthesis at L3–L4) was simulated as a proof of concept, and showed plausible results. Despite the numerous limitations of this approach which will be addressed in future implementations, the preliminary outcome is promising and encourages a wide effort toward its refinement.

The American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) Surgical Risk Calculator (SRC) is a novel universal risk calculator designed to aid in risk stratification of patients undergoing various types of major surgery. The purpose of this study was to assess the validity of the ACS NSQIP SRC in predicting postoperative complications in patients undergoing microvascular head and neck reconstruction. A retrospective cohort study of patients undergoing head and neck microvascular reconstruction with fibular free flaps at a single institution was completed. The NSQIP SRC was used to compute complication risk estimates and length of stay (LOS) estimates for all patients under study. Associations between complication risk estimates generated by the SRC and actual rates of observed complications were evaluated using logistic regression models. Logistic regression models also were used to evaluate the SRC estimates for LOS duration compared with the actual observed LOS after surgery. Of 153 patients under study, 46 (30%) developed a postoperative complication corresponding to those defined by NSQIP SRC. Thirty-eight patients (25%) developed a postoperative complication categorized as severe in the parameters of the NSQIP SRC. None of the SRC complication estimates showed a statistically relevant association with the corresponding observed rates of complications. The mean LOS predicted by the SRC was 8.0 days (median, 7.5 days; interquartile range [IQR], 6.5 to 9; range, 5.0 to 18.5 days). The mean observed LOS for the study group was 9.6 days (median, 7.0 days; IQR, 6 to 9; range, 5 to 67 days). Lin's (Biometrics 45:255, 1989) concordance correlation coefficient to measure agreement between observed and predicted LOS was 0.10, indicating only slight agreement between the 2 values. The ACS NSQIP SRC is not a useful risk-stratifying metric for patients undergoing major head and neck reconstruction with microvascular fibular free flaps. The SRC also does not accurately predict hospital LOS for this same patient cohort. Copyright © 2016 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.

The aim of this study was to assess surgical plan modification after 3-demensional (3D) simulation. The procedures were to perform traditional surgical planning, construction of 3D model for the initial surgical plan (P1), 3D model of altered surgical plan after simulation (P2), comparison between P1 and P2 models, surgical execution, and postoperative validation using superimposition and root-mean-square difference (RMSD) between postoperative 3D image and P2 simulation model. Surgical plan was modified after 3D simulation in 93% of the cases. Absolute linear changes of landmarks in mediolateral direction (x-axis) were significant and between 1.11 to 1.62 mm. The pitch, yaw, and roll rotation as well as ramus inclination correction also showed significant changes after the 3D planning. Yaw rotation of the maxillomandibular complex (1.88 ± 0.32°) and change of ramus inclination (3.37 ± 3.21°) were most frequently performed for correction of the facial asymmetry. Errors between the postsurgical image and 3D simulation were acceptable, with RMSD 0.63 ± 0.25 mm for the maxilla and 0.85 ± 0.41 mm for the mandible. The information from this study could be used to augment the clinical planning and surgical execution when a conventional approach is applied. PMID:28071714

Comparative outcomes of patients undergoing pericardiocentesis or pericardial window are limited. Development of pericardial effusion after cardiac surgery is common but no data exist to guide best management. Procedural billing codes and Cleveland Clinic surgical registries were used to identify 1,281 patients who underwent either pericardiocentesis or surgical pericardial window between January 2000 and December 2012. The 656 patients undergoing an intervention for a pericardial effusion secondary to cardiac surgery were also compared. Propensity scoring was used to identify well-matched patients in each group. In the overall cohort, in-hospital mortality was similar between the group undergoing pericardiocentesis and surgical drainage (5.3% vs 4.4%, p = 0.49). Similar outcomes were found in the propensity-matched group (4.9% vs 6.1%, p = 0.55). Re-accumulation was more common after pericardiocentesis (24% vs 10%, p <0.0001) and remained in the matched cohorts (23% vs 9%, p <0.0001). The secondary outcome of hemodynamic instability after the procedure was more common in the pericardial window group in both the unmatched (5.2% vs 2.9%, p = 0.036) and matched cohorts (6.1% vs 2.0%, p = 0.022). In the subgroup of patients with a pericardial effusion secondary to cardiac surgery, there was a lower mortality after pericardiocentesis in the unmatched group (1.5% vs 4.6%, p = 0.024); however, after adjustment, this difference in mortality was no longer present (2.6% vs 4.5%, p = 0.36). In conclusion, both pericardiocentesis and surgical pericardial window are safe and effective treatment strategies for the patient with a pericardial effusion. In our study there were no significant differences in mortality in patients undergoing either procedure. Observed differences in outcomes with regard to recurrence rates, hemodynamic instability, and in those with postcardiac surgery effusions may help to guide the clinician in management of the patient requiring therapeutic or diagnostic drainage of a pericardial effusion.

Growing prostheses accommodate skeletally immature patients with bone tumors undergoing limb-preserving surgery. Early devices required surgical procedures for lengthening; recent devices lengthen without surgery. Expenses for newer expandable devices that lengthen without surgery are more than for their predecessors but overall reimbursement amounts are not known. We sought to determine reimbursement amounts associated with lengthening of growing prostheses requiring surgical and nonsurgical lengthening. We retrospectively reviewed 17 patients with growing prostheses requiring surgical expansion and eight patients with prostheses capable of nonsurgical expansion. Insurance documents were reviewed to determine the reimbursement for implantation, lengthening, and complications. Growth data were obtained from the literature. Mean reimbursement amounts of surgical and nonsurgical lengthenings were $9950 and $272, respectively. Estimated reimbursements associated with implantation of a growing prosthesis varied depending on age, sex, and location. The largest difference was found for 4-year-old boys with distal femoral replacement where reimbursement for expansion to maturity for surgical and nonsurgical lengthening prostheses would be $379,000 and $208,000, respectively. For children requiring more than one surgical expansion, net reimbursements were lower when a noninvasive lengthening device was used. Annual per-prosthesis maintenance reimbursements to address complications for surgical and nonsurgical lengthening prostheses were $3386 and $1856, respectively. This study showed that reimbursements for lengthening of growing endoprostheses capable of nonsurgical expansion may be less expensive in younger patients, particularly male patients undergoing distal femur replacement, than endoprostheses requiring surgical lengthening. Longer outcomes studies are required to see if reimbursements for complications differ between devices. Level III, economic and decision analysis.

ABSTRACT Objectives: To describe the rate of surgical site infections in children undergoing orthopedic surgery in centers of excellence and analyze the patients’ profiles. Methods: Medical records of pediatric patients undergoing orthopedic surgery in the Jamil Haddad National Institute of Traumatology and Orthopedics from January 2012 to December 2013 were analyzed and monitored for one year. Patients diagnosed with surgical site infection were matched with patients without infection by age, date of admission, field of orthopedic surgery and type of surgical procedure. Patient, surgical and follow-up variables were examined. Descriptive, bivariate and correspondence analyses were performed to evaluate the patients’ profiles. Results: 347 surgeries and 10 surgical site infections (2.88%) were identified. There was association of infections with age - odds ratio (OR) 11.5 (confidence interval - 95%CI 1.41-94.9) -, implant - OR 7.3 (95%CI 1.46-36.3) -, preoperative period - OR 9.8 (95%CI 1.83-53.0), and length of hospitalization - OR 20.6 (95%CI 3.7-114.2). The correspondence analysis correlated the infection and preoperative period, weight, weight Z-score, age, implant, type of surgical procedure, and length of hospitalization. Average time to diagnosis of infection occurred 26.5±111.46 days after surgery. Conclusions: The rate of surgical site infection was 2.88%, while higher in children over 24 months of age who underwent surgical implant procedures and had longer preoperative periods and lengths of hospitalization. This study identified variables for the epidemiological surveillance of these events in children. Available databases and appropriate analysis methods are essential to monitor and improve the quality of care offered to the pediatric population. PMID:28977312

Current Management of Presbyopia

2014-01-01

Presbyopia is a physiologic inevitability that causes gradual loss of accommodation during the fifth decade of life. The correction of presbyopia and the restoration of accommodation are considered the final frontier of refractive surgery. Different approaches on the cornea, the crystalline lens and the sclera are being pursued to achieve surgical correction of this disability. There are however, a number of limitations and considerations that have prevented widespread acceptance of surgical correction for presbyopia. The quality of vision, optical and visual distortions, regression of effect, complications such as corneal ectasia and haze, anisometropia after monovision correction, impaired distance vision and the invasive nature of the currently techniques have limited the utilization of presbyopia surgery. The purpose of this paper is to provide an update of current procedures available for presbyopia correction and their limitations. PMID:24669140

The accurate reduction of tibial plateau malunions can be challenging without guidance. In this work, we report on a novel technique that combines 3-dimensional computer-assisted planning with patient-specific surgical guides for improving reliability and accuracy of complex intraarticular corrective osteotomies. Preoperative planning based on 3-dimensional bone models was performed to simulate fragment mobilization and reduction in 3 cases. Surgical implementation of the preoperative plan using patient-specific cutting and reduction guides was evaluated; benefits and limitations of the approach were identified and discussed. The preliminary results are encouraging and show that complex, intraarticular corrective osteotomies can be accurately performed with this technique. For selective patients with complex malunions around the tibia plateau, this method might be an attractive option, with the potential to facilitate achieving the most accurate correction possible.

Refractive error is one of leading ophthalmic diseases for both genders all over the world. Laser refractive correction surgery, e.g., laser in-situ keratomileusis (LASIK), has been commonly used worldwide. The prediction of surgical parameters, e.g., corneal ablation depth, depends on the doctor’s experience, theoretical formula and surgery reference manual in the preoperative diagnosis. The error of prediction may present a potential surgical risk and complication. Being aware of the surgery parameters is important because these can be used to estimate a patient’s post-operative visual quality and help the surgeon plan a suitable treatment. Therefore, in this paper we discuss data mining techniques that can be utilized for the prediction of laser refractive correction surgery parameters. It can provide the surgeon with a reference for possible surgical parameters and outcomes of the patient before the laser refractive correction surgery.

Is circumferential minimally invasive surgery effective in the treatment of moderate adult idiopathic scoliosis?

Outcomes for minimally invasive scoliosis correction surgery have been reported for mild adult scoliosis. Larger curves historically have been treated with open surgical procedures including facet resections or posterior column osteotomies, which have been associated with high-volume blood loss. Further, minimally invasive techniques have been largely reported in the setting of degenerative scoliosis. We describe the effects of circumferential minimally invasive surgery (cMIS) for moderate to severe scoliosis in terms of (1) operative time and blood loss, (2) overall health and disease-specific patient-reported outcomes, (3) deformity correction and fusion rate, and (4) frequency and types of complications. Between January 2007 and January 2012, we performed 50 cMIS adult idiopathic scoliosis corrections in patients with a Cobb angle of greater than 30° but less than 75° who did not have prior thoracolumbar fusion surgery; this series represented all patients we treated surgically during that time meeting those indications. Our general indications for this approach during that period were increasing back pain unresponsive to nonoperative therapy with cosmetic and radiographic worsening of curves. Surgical times and estimated blood loss were recorded. Functional clinical outcomes including VAS pain score, Oswestry Disability Index (ODI), and SF-36 were recorded preoperatively and postoperatively. Patients' deformity correction was assessed on pre- and postoperative 36-inch (91-cm) standing films and fusion was assessed on CT scan. Minimum followup was 24 months (mean, 48 months; range, 24-77 months). Mean blood loss was 613 mL for one-stage surgery and 763 mL for two-stage surgery. Mean operative time was 351 minutes for one-stage surgery and 482 minutes for two-stage surgery. At last followup, mean VAS and ODI scores decreased from 5.7 and 44 preoperatively to 2.9 and 22 (p < 0.001 and 0.03, respectively) and mean SF-36 score increased from 48 preoperatively to 74 (p = 0.026). Mean Cobb angle and sagittal vertical axis decreased from 42° and 51 mm preoperatively to 16° and 27 mm postoperatively (both p < 0.001). An 88% fusion rate was confirmed on CT scan. Perioperative complications occurred in 11 of the 50 patients (22%), with delayed complications needing further surgery in 10 more patients at last followup. cMIS provides for good clinical and radiographic outcomes for moderate (30°-75°) adult idiopathic scoliosis. Patients undergoing cMIS should be carefully selected to avoid fixed, rigid deformities and a preoperative sagittal vertical axis of greater than 10 cm; surgeons should consider alternative techniques in those patients.

Surgical site infection has been identified as one of the most important preventable sources of morbidity and mortality associated with medical treatment. The purpose of the present study was to evaluate the feasibility and efficacy of an institutional prescreening program for the preoperative detection and eradication of both methicillin-resistant and methicillin-sensitive Staphylococcus aureus in patients undergoing elective orthopaedic surgery. Data were collected prospectively during a single-center study. A universal prescreening program, employing rapid polymerase chain reaction analysis of nasal swabs followed by an eradication protocol of intranasal mupirocin and chlorhexidine showers for identified carriers, was implemented. Surgical site infection rates were calculated and compared with a historical control period immediately preceding the start of the screening program. During the study period, 7019 of 7338 patients underwent preoperative screening before elective surgery, for a successful screening rate of 95.7%. One thousand five hundred and eighty-eight (22.6%) of the patients were identified as Staphylococcus aureus carriers, and 309 (4.4%) were identified as methicillin-resistant Staphylococcus aureus carriers. A significantly higher rate of surgical site infection was observed among methicillin-resistant Staphylococcus aureus carriers (0.97%; three of 309) compared with noncarriers (0.14%; seven of 5122) (p = 0.0162). Although a higher rate of surgical site infection was also observed among methicillin-sensitive Staphylococcus aureus carriers (0.19%; three of 1588) compared with noncarriers, this difference did not achieve significance (p = 0.709). Overall, thirteen cases of surgical site infection were identified during the study period, for an institutional infection rate of 0.19%. This rate was significantly lower than that observed during the control period (0.45%; twenty-four cases of surgical site infection among 5293 patients) (p = 0.0093). Implementation of an institution-wide prescreening program for the identification and eradication of methicillin-resistant and methicillin-sensitive Staphylococcus aureus carrier status among patients undergoing elective orthopaedic surgery is feasible and can lead to significant reductions in postoperative rates of surgical site infection.

Abdominal surgical site infections (SSI) cause substantial morbidity and mortality for patients undergoing operative procedures. We determined the incidence of and risk factors for SSI after abdominal surgery in the Department of Abdominal Surgery at the University Clinical Centre of Kosovo (UCCK). Prospective surveillance of patients undergoing abdominal surgery was performed between December 2005 and June 2006. CDC definitions were followed to detect SSI and study forms were based on Europe Link for Infection Control through Surveillance (HELICS) protocol. A total of 253 surgical interventions in 225 patients were evaluated. The median age of patients was 42 years and 55.1% of them were male. The overall incidence rate of SSI was 12%. Follow-up was achieved for 84.1% of the procedures. For patients with an SSI, the median duration of hospitalization was 9 days compared with 4 days for those without an SSI (p2, use of antibiotic prophylaxis and NNIS class of >2 were all significant at p < .001. The SSI rates for the NNIS System risk classes 0, 1 and 2-3 were 4.2%, 46.7% and 100%, respectively. SSI caused considerable morbidity among surgical patients in UCCK. Appropriate active surveillance and infection control measures should be introduced during preoperative, intra-operative, and postoperative care to reduce infection rates.

Muscle weakness due to trauma from the surgical approach is anticipated to affect the ability of the patient to undertake daily physical activity early after total hip arthroplasty (THA). The objective of this study was to compare daily physical activity on days 1 to 4 after discharge, in patients following THA performed by 1 of 3 surgical approaches. A cohort study included 60 hip osteoarthritis patients, scheduled for THA, allocated to direct lateral approach, posterior approach, or anterior approach. Daily physical activity was measured by an accelerometer, with upright time per 24 hours as primary outcome and walking time, number of steps, and number of upright events per 24 hours as secondary outcomes. There were no statistically significant group differences in any of the measures of daily physical activity (P > 0.290) or between days of follow-up (P > 0.155). Overall, the median participant had 3.50 hours (interquartile range, 2.85-4.81 hours) of upright time, and participants showed wide variation in all outcomes of daily physical activity. There were no differences in daily physical activity between THA patients undergoing different surgical approaches. The surgical approach may not be a limiting factor for daily physical activity early after surgery in a fast-track treatment course.

To examine the effects of obesity on specialty-specific surgical outcomes in children. Retrospective cohort study using the National Surgical Quality Improvement Program, Pediatric, 2012-2014. Patients included those aged 2-17 years who underwent a surgical procedure in one of six specialties. Obesity was the primary patient variable of interest. Outcomes of interest were postoperative complications and operative times. Odds ratios for development of postoperative complications were calculated using stepwise multivariate regression analysis. Obesity was associated with a significantly greater risk of wound complications (OR 1.24, 95% CI 1.13-1.36), but decreased risk of non-wound complications (OR 0.68, 95% CI 0.63-0.73) and morbidity (OR 0.79, 95% CI 0.75-0.84). Obesity was not a significant factor in predicting postoperative complications in patients undergoing otolaryngology or plastic surgery procedures. Anesthesia times and operative times were significantly longer for obese patients undergoing most types of pediatric surgical procedures. Obesity confers an increased risk of wound complications in some pediatric surgical specialties and is associated with overall decreased non-wound complications and morbidity. These findings suggest that the relationship between obesity and postoperative complications is complex and may be more dependent on underlying procedure- or specialty-related factors than previously suspected.

A comparison of piezosurgery and conventional surgery by heat shock protein 70 expression.

The effects of mechanical instruments on the viability of cells are essential in terms of regeneration. There is considerable interest in cell repair following damage mediated by dental surgical procedures. Cells can tolerate stress by expressing heat shock protein 70 (Hsp70). During and after surgical tooth removal, oxidative stress can activate Hsp70 expression proportional to the intensity of the stress signal stimulus to cope with stress. This study examined the expression of Hsp70 as a potential biomarker of immediate postoperative stress in patients undergoing two different surgical procedures of different severity. Expression of Hsp70 both at mRNA and at protein level in the conventional group was two-fold higher than that of the piezo group. This suggests that tooth movement by the piezo method causes relatively lower stress in the alveolar bone. Piezosurgery provides relatively low stress to the patients and this may help cell repair after the surgical procedure. Patients undergoing more aggressive surgery using conventional methods showed a significant increase in Hsp70 in the immediate postoperative period. Therefore, Hsp70 induction can be a potential tool as a prognostic surgical marker. Copyright © 2012 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

If a skeletal anterior open bite malocclusion is treated by orthognathic surgery directed only at the mandible, the lower jaw is repositioned upward in a counter-clockwise rotation. However, this procedure has a high risk of relapse. In the present study, the key factors associated with post-surgical stability of corrected skeletal anterior open bite malocclusions were investigated. Eighteen orthognathic patients were subjected to cephalometric analysis to assess the dental and skeletal changes following mandibular surgery for the correction of an anterior open bite. The patients were divided into two groups, determined by an increase or decrease in nasion-menton (N-Me) distance as a consequence of surgery. Changes in overbite, the displacements of molars and positional changes in Menton were evaluated immediately before and after surgery and after a minimum of one year post-operatively. The group with a decreased N-Me distance exhibited a significantly greater backward positioning of the mandible. The group with an increased N-Me distance experienced significantly greater dentoalveolar extrusion of the lower molars. A sufficient mandibular backward repositioning is an effective technique in the prevention of open bite relapse. In addition, it is important not to induce molar extrusion during post-surgical orthodontic treatment to preserve stability of the surgical open bite correction.

Surgical Options for the Refractive Correction of Keratoconus: Myth or Reality

Zaldivar, R.; Aiello, F.; Madrid-Costa, D.

2017-01-01

Keratoconus provides a decrease of quality of life to the patients who suffer from it. The treatment used as well as the method to correct the refractive error of these patients may influence on the impact of the disease on their quality of life. The purpose of this review is to describe the evidence about the conservative surgical treatment for keratoconus aiming to therapeutic and refractive effect. The visual rehabilitation for keratoconic corneas requires addressing three concerns: halting the ectatic process, improving corneal shape, and minimizing the residual refractive error. Cross-linking can halt the disease progression, intrastromal corneal ring segments can improve the corneal shape and hence the visual quality and reduce the refractive error, PRK can correct mild-moderate refractive error, and intraocular lenses can correct from low to high refractive error associated with keratoconus. Any of these surgical options can be performed alone or combined with the other techniques depending on what the case requires. Although it could be considered that the surgical option for the refracto-therapeutic treatment of the keratoconus is a reality, controlled, randomized studies with larger cohorts and longer follow-up periods are needed to determine which refractive procedure and/or sequence are most suitable for each case.

Multiple complications are associated with use of ventricular assist devices (VADs). Cardiac-related complications and infections are most frequently reported. VADs, however, can also lead to a number of general surgical complications equally significant in terms of morbidity and mortality. The authors performed a systematic literature search to review current data that specifically relate general surgical complications to patients who undergo left VAD implantation. The review provides a relatively clear understanding of the spectrum of general surgical complications and shows that they contribute significantly to morbidity and mortality in these patients.

OBJECTIVE The objective of this study was to evaluate the clinical efficacy of posterior-only surgical correction of dystrophic scoliosis in patients with neurofibromatosis Type 1 (NF1) using a multiple anchor point method (MAPM). METHODS From 2005 to 2014, 31 patients (mean age 13.5 years old, range 10-22 years old) suffering from dystrophic scoliosis associated with NF1 underwent posterior-only surgical correction using a MAPM. The apex of the deformity was thoracic (n = 25), thoracolumbar (n = 4), and lumbar (n = 2). The mean preoperative coronal Cobb angle was 69.1° (range 48.9°-91.4°). The mean Cobb angle on the side-bending radiograph of the convex side was 58.2° (range 40°-79.8°). The mean flexibility and apical vertebral rotation (AVR) were 15.6% (range 8.3%-28.2%) and 2.5° (range 2°-3°), respectively. The mean angle of sagittal kyphosis was 58.3° (range 34.1°-79.6°). RESULTS The mean follow-up period was 53 months (range 12-96 months). The mean postoperative coronal Cobb angle was 27.4° (range 16.3°-46.7°). Postoperatively, the mean AVR and angle of sagittal kyphosis were 1.2° (range 1°-2°) and 22.4° (range 4.2°-36.3°), respectively. All patients showed good correction of all indices postoperatively. The mean postoperative correction rate was 58.7% (range 46.3%-74.1%). At the final follow-up evaluation, the corrective loss rate of the Cobb angle was only 2.3%. Only 1 patient required revision surgery. No severe complications such as spinal cord, neural, or large vascular injury occurred during the operation. CONCLUSIONS Posterior-only surgical correction of dystrophic scoliosis in patients with NF1 using a MAPM could yield satisfactory clinical efficacy of correction and fusion.

Surgical smoke.

2009-10-01

Surgical smoke is the gaseous by-product formed during surgical procedures. Most surgeons, operating theatre staff and administrators are unaware of its potential health risks. Surgical smoke is produced by various surgical instruments including those used in electrocautery, lasers, ultrasonic scalpels, high speed drills, burrs and saws. The potential risks include carbon monoxide toxicity to the patient undergoing a laparoscopic operation, pulmonary fibrosis induced by non-viable particles, and transmission of infectious diseases like human papilloma virus. Cytotoxicity and mutagenicity are other concerns. Minimisation of the production of surgical smoke and modification of any evacuation systems are possible solutions. In general, a surgical mask can provide more than 90% protection to exposure to surgical smoke; however, in most circumstances it cannot provide air-tight protection to the user. An at least N95 grade or equivalent respirator offers the best protection against surgical smoke, but whether such protection is necessary is currently unknown.

Open esophagectomy is a high-risk procedure in patients with liver cirrhosis. With the advent of minimally invasive surgical techniques, the overall morbidity and mortality rates of esophagectomy have decreased. The aim of this study was to describe short-term outcomes of minimally invasive esophagectomy in patients with proven liver cirrhosis. Retrospective observational cohort study. Demographics, preoperative clinical characteristics, and outcomes of patients undergoing minimally invasive esophagectomy for carcinoma were analyzed. Patients with concomitant liver cirrhosis were compared to patients without liver cirrhosis undergoing similar surgical procedures. In addition, variables possibly associated with postoperative morbidity and mortality in patients with cirrhosis were investigated. Out of 443 patients undergoing minimally invasive esophagectomy, 18 (4.1%) had concomitant liver cirrhosis. Demographics and preoperative clinical variables were similar in the 2 patient groups. While the overall morbidity rate was similar, the 90-day mortality rate was significantly higher in patients with liver cirrhosis (P = .023). There was a significantly higher rate of sepsis and anastomotic, respiratory, and hemorrhagic complications in patients with liver cirrhosis who died in the postoperative period. Minimally invasive esophagectomy is feasible in patients with liver cirrhosis. Future strategies should focus on total minimally invasive procedures and early recognition of surgical complications.

To study patients with mechanical heart valves undergoing non-cardiac surgery and their anticoagulation management during these procedures. It was a cohort study. The study was conducted at the Department of Cardiac Surgery, Punjab Institute of Cardiology, Lahore and Department of Surgery, Services Institute of Medical Sciences, Lahore, from September 1994 to June 2006. Patients with mechanical heart valves undergoing non-cardiac surgical operation during this period, were included. Their anticoagulation was monitored and anticoagulation related complications were recorded. In this study, 507 consecutive patients with a mechanical heart valve replacement were followed-up. Forty two (8.28%) patients underwent non-cardiac surgical operations of which 24 (57.1%) were for abdominal and non-abdominal surgeries, 5 (20.8%) were emergency and 19 (79.2%) were planned. There were 18 (42.9%) caesarean sections for pregnancies. Among the 24 procedures, there were 7(29.1%) laparotomies, 7(29.1%) hernia repairs, 2 (8.3%) cholecystectomies, 2 (8.3%) hysterectomies, 1(4.1%) craniotomy, 1(4.1%) spinal surgery for neuroblastoma, 1(4.1%) ankle fracture and 1(4.1%) carbuncle. No untoward valve or anticoagulation related complication was seen during this period. Patients with mechanical valve prosthesis on life-long anticoagulation, if managed properly, can undergo any type of non-cardiac surgical operation with minimal risk.

Vulvar LS can be a debilitating disease, causing pruritus and pain, and it carries the potential for atrophy, scarring, and significant functional impairment. Recently, many advances have been made regarding the etiology and natural history of the disease process; however, much debate still exists regarding the most advantageous medical and surgical management of this disorder. In an effort to provide a comprehensive review on current vulvar LS literature, the following three controversies will be discussed: (1) optimal disease treatment, (2) theories behind LS's oncogenicity and treatments for minimizing malignancy, and (3) the value of surgical treatment for LS. Ultra-potent topical corticosteroids (TCSs) are the first-line treatment for vulvar LS, while topical calcineurin inhibitors (TCIs) remain second-line agents for patients for whom TCS treatment resulted in incomplete resolution of symptoms or adverse events. Due to the relapsing nature of the disease, long-term maintenance therapy is often required. In addition, recent advances have contributed to the understanding of the association between LS and squamous cell carcinoma (SCC). While the exact mechanism responsible for LS-associated SCC is not known, immune dysregulation and inflammation may play an important role; therefore, successful treatment of LS should be directed towards alleviation of symptoms and reversal of the underlying histopathologic changes. Patients with LS-associated malignancy, as well as patients who need correction of functionally restrictive, scarring processes, can successfully undergo surgical intervention with tissue conservation. © 2013 Elsevier Inc.

Objectives To evaluate knee function in patients undergoing reconstruction of the anterior cruciate ligament (ACL) using the central third of the patellar ligament or the medial flexor tendons of the knee, i.e. quadruple ligaments from the semitendinosus and gracilis (ST-G), by means of the Knee Society Score (KSS) and the Lysholm scale. Methods This was a randomized prospective longitudinal study on 40 patients who underwent arthroscopic ACL reconstruction between September 2013 and August 2014. They comprised 37 males and three females, with ages ranging from 16 to 52 years. The patients were numbered randomly from 1 to 40: the even numbers underwent surgical correction using the ST-G tendons and the odd numbers, using the patellar tendon. Functional evaluations were made using the KSS and Lysholm scale, applied in the evening before the surgical procedure and six months after the operation. Results From the statistical analysis, it could be seen that the patients’ functional capacity was significantly greater after the operation than before the operation. There was strong evidence that the two forms of therapy had similar results (p = >0.05), in all the comparisons. Conclusions The results from the ACL reconstructions were similar with regard to functional recovery of the knee and improvement of quality of life, independent of the type of graft. It was not possible to identify the best method of surgical treatment. The surgeon's clinical and technical experience and the patient are the factors that determine the choice of graft type for use in ACL surgery. PMID:27218084

AIM To evaluate surgical outcomes (SOs) and visual outcomes (VOs) in cataract surgery comparing the Centurion® phacoemulsification system (CPS) with the Infiniti® phacoemulsification system (IPS). METHODS Prospective, consecutive study in a single-site private practice. Totally 412 patients undergoing cataract surgery with either the CPS using the 30-degree balanced® tip (n=207) or the IPS using the 30-degree Kelman® tip (n=205). Intraoperative and postoperative outcomes were documented prospectively up to one month follow-up. Nuclear sclerosis (NS) grade, cumulated dissipated energy (CDE), preoperative corrected distance visual acuity (CDVA), and CDVA at one month were recorded. RESULTS CDE was 13.50% less in the whole CPS compared with the whole IPS subcohort. In eyes with NS grade III or greater, CDE was 28.87% less with CPS (n=70) compared with IPS (n=44) (P=0.010). Surgical complications were not statistically different between the two subcohorts (P=0.083), but in the one case of vitreous loss using the CPS, CDVA of 6/4 was achieved at one month. The mean CDVAs (VOs) at one month for NS grade III and above cataracts were -0.17 logMAR (6/4.5) in the CPS and -0.15 logMAR (6/4.5) in the IPS subcohort respectively (P=0.033). CONCLUSION CDE is 28.87% less, and VOs are significantly improved, in denser cataracts in the CPS compared with the IPS. The authors recommend the CPS for cases with denser nuclei. PMID:29181313

Pediatric surgical training in the United States remained basically unchanged from the model developed by Ladd and Gross in the 1930s until recently. Standardized curriculum and novel evaluation methods are now being implemented. Pediatric Surgical education is currently undergoing a transition to competency-based evaluation and promotion. Unfortunately, there is little data on the efficacy of these changes. This presents an opportunity for further study of how we conduct training, and how we evaluate and promote our trainees.

Bulking agents provide an alternative option in the management of women with stress urinary incontinence and they seem to have an important role in the management flow chart of SUI. However, evidence on this issue is scanty. The most important aspect is to understand whether bulking agents are comparable with the other first-line anti-incontinence surgical procedure (MUS, Burch colposuspension and pubovaginal slings). Hence, the primary aim of the current review was to assess the objective and subjective outcomes of bulking agents in comparison with the other surgical procedures for the treatment of SUI. PubMed and Medline were systematically searched and we included studies evaluating the use of bulking agents in comparison with other surgical approaches for either primary or recurrent treatment of female SUI. Three studies meeting the inclusion criteria were identified. Two of these studies were RCTs evaluating the use of bulking agents versus other surgical procedures for the treatment of primary female SUI; the remnant article was a retrospective cohort study that compared the effectiveness and safety of repeat midurethral sling with urethral bulking after failed midurethral sling. The combined results of all analyses showed that the objective recurrence rate of peri- or trans-urethral injections is significantly higher in comparison with the other surgical procedures. Similar findings were observed when considering separately the treatment for primary or recurrent SUI. Furthermore, lower subjective recurrence rate was observed among patients undergoing other surgical treatment in comparison with those undergoing bulking agents; however, this trend was not statistically significant. Moreover, patients undergoing injection of bulking agents experienced a lower rate of voiding dysfunctions in comparison to the control group. According to current evidence, bulking agents should not be proposed as first-line treatment in those women seeking permanent cure for both primary and recurrent SUI. However, the effectiveness of a procedure should be balanced with its invasiveness and patients' expectations. Bulking agents are a minimally invasive approach to treat SUI and their use should be considered as an alternative strategy particularly in special conditions: patients who are fragile, in those who do not wish to have surgery, or in whom surgical options are restricted (postoperatively, after irradiation).

What surgical approaches for vestibular schwannomas (VS) are best for complete resection and facial nerve (FN) preservation when serviceable hearing is present? There is insufficient evidence to support the superiority of either the middle fossa (MF) or the retrosigmoid (RS) approach for complete VS resection and FN preservation when serviceable hearing is present. Which surgical approach (RS or translabyrinthine [TL]) for VS is best for complete resection and FN preservation when serviceable hearing is not present? There is insufficient evidence to support the superiority of either the RS or the TL approach for complete VS resection and FN preservation when serviceable hearing is not present. Does VS size matter for facial and vestibulocochlear nerve preservation with surgical resection? Level 3: Patients with larger VS tumor size should be counseled about the greater than average risk of loss of serviceable hearing. Should small intracanalicular tumors (<1.5 cm) be surgically resected? There are insufficient data to support a firm recommendation that surgery be the primary treatment for this subclass of VSs. Is hearing preservation routinely possible with VS surgical resection when serviceable hearing is present? Level 3: Hearing preservation surgery via the MF or the RS approach may be attempted in patients with small tumor size (<1.5 cm) and good preoperative hearing. When should surgical resection be the initial treatment in patients with neurofibromatosis type 2 (NF2)? There is insufficient evidence that surgical resection should be the initial treatment in patients with NF2. Does a multidisciplinary team, consisting of neurosurgery and neurotology, provides the best outcomes of complete resection and facial/vestibulocochlear nerve preservation for patients undergoing resection of VSs? There is insufficient evidence to support stating that a multidisciplinary team, usually consisting of a neurosurgeon and a neurotologist, provides superior outcomes compared to either subspecialist working alone. Does a subtotal surgical resection of a VS followed by stereotactic radiosurgery (SRS) to the residual tumor provide comparable hearing and FN preservation to patients who undergo a complete surgical resection? There is insufficient evidence to support subtotal resection (STR) followed by SRS provides comparable hearing and FN preservation to patients who undergo a complete surgical resection. Does surgical resection of VS treat preoperative balance problems more effectively than SRS? There is insufficient evidence to support either surgical resection or SRS for treatment of preoperative balance problems. Does surgical resection of VS treat preoperative trigeminal neuralgia more effectively than SRS? Level 3: Surgical resection of VSs may be used to better relieve symptoms of trigeminal neuralgia than SRS. Is surgical resection of VSs more difficult (associated with higher facial neuropathies and STR rates) after initial treatment with SRS? Level 3: If microsurgical resection is necessary after SRS, it is recommended that patients be counseled that there is an increased likelihood of a STR and decreased FN function.  The full guideline can be found at: https://www.cns.org/guidelines/guidelines-management-patients-vestibular-schwannoma/chapter_8.

2017-08-01

The surgical treatment of malunions after midshaft clavicle fractures is associated with a number of potential complications and the surgical procedure is challenging. However, with appropriate and meticulous preoperative surgical planning, the surgical correction yields satisfactory results. The purpose of this study was to provide a guideline and detailed overview for the computer-assisted planning and 3-dimensional (3D) correction of malunions of the clavicle. The 3D bone surface models of the pathologic and contralateral sides were created on the basis of computed tomography data. The computer-assisted assessment of the deformity, the preoperative plan, and the design of patient-specific guides enabling compression plating are described. We demonstrate the benefit and versatility of computer-assisted planning for corrective osteotomies of malunions of the midshaft clavicle. In combination with patient-specific guides and compression plating technique, the correction can be performed in a more standardized fashion. We describe the determination of the contact-optimized osteotomy plane. An osteotomy along this plane facilitates the correction and enlarges the contact between the fragments at once. We further developed a technique of a stepped osteotomy that is based on the calculation of the contact-optimized osteotomy plane. The stepped osteotomy enables the length to be restored without the need of structural bone graft. The application of the stepped osteotomy is presented for malunions of the clavicle with shortening and excessive callus formation. The 3D preoperative planning and patient-specific guides for corrective osteotomies of the clavicle may help reduce the number of potential complications and yield results that are more predictable.

To compare survival and complications in horses undergoing large colon resection with either sutured end-to-end or stapled functional end-to-end anastomoses. Retrospective cohort study. Twenty-six client-owned horses with gastrointestinal disease. Retrospective data were retrieved from the medical records of 26 horses undergoing colectomy, including 14 horses with sutured end-to-end and 12 horses with stapled functional end-to-end anastomoses, between 2003 and 2016. Records were evaluated for signalment, medical and surgical treatments, and survival to hospital discharge. Long-term follow-up was obtained through owner contact. Continuous variables were compared with Mann-Whitney tests. Fisher's exact testing was used to compare survival to hospital discharge. Survival time was compared by constructing Kaplan-Meier survival curves and performing log-rank curve comparison testing. Mean age of horses undergoing colectomy was 13 years. Reason for colectomy was prophylaxis (12) or salvage (14). Mean surgical time was 169 minutes. Mean hospitalization time was 9 days, which did not differ with anastomosis type (P = .62). Nine of 12 horses undergoing stapled functional end-to-end anastomosis and 12 of 14 horses undergoing sutured end-to-end anastomosis survived to hospital discharge (P = .63). Survival time did not differ with anastomosis technique (P = .35). Short- and long-term survival outcomes are not different between sutured end-to-end or stapled functional end-to-end anastomoses in horses undergoing colectomy. © 2017 The American College of Veterinary Surgeons.

Adolescent varicocele: Tauber antegrade sclerotherapy versus Palomo repair.

PubMed

Mazzoni, G; Spagnoli, A; Lucchetti, M C; Villa, M; Capitanucci, M L; Ferro, F

2001-10-01

There is general agreement on treatment for varicocele in pediatric patients. Randomized prospective studies have shown that anatomical and functional lesions may be corrected. Due to the impossibility of seminal examination patients with moderate to large varicocele or ipsilateral testicular hypertrophy, characterized by a change in testicular consistency or symptoms, should undergo surgical correction. The best therapeutic approach is still under discussion. At 2 centers 2 therapeutic approaches to varicocele treatment in pediatric patients were compared, namely the Palomo repair and antegrade sclerotherapy according to Tauber. The 89 patients from the same geographical area elected 1 procedure after an explanation. From the medical records we retrospectively evaluated operative time, postoperative analgesics, postoperative fever onset, complications, convalescence, recurrence and postoperative hydrocele. After Palomo repair in 45 patients there were 2 recurrences (4.4%) and 2 postoperative hydroceles (4.4%). Of 44 antegrade sclerotherapy cases 1 was converted to Palomo repair, there was no hydrocele formation and recurrence developed in 2 (4.5%). Testicular atrophy was not observed in any patient regardless of the method used. The cost of the procedure was lower in the sclerotherapy group. These data suggest that the failure rate was similar in both groups. The principal advantages of sclerotherapy are simplicity, decreased cost and lack of hydrocele formation.

the surgical correction of tetralogy of Fallot (TOF) is standardized on the way to close the septal defect, but differs in the way of expanding the right ventricular outflow tract (RVOT). The aim was to compare the early postoperative clinical course of the RVOT obstruction enlargement in classical ventriculotomy technique and the small infundibulectomy (SI). We analyzed the database of the pediatric heart surgery service from 2008 to 2011. Patients with non-complex TOF undergoing complete correction by classical ventriculotomy or SI were selected. Anova, χ(2) and Fisher statistical test were applied. the data included 47 patients, 55 % (26) male, mean age 43 months (6-172), classical ventriculotomy was performed in 61.7 % (29). This group had higher peak levels of lactate (9.07 versus 6.8 mmol/L) p = 0049, and greater magnitude in the index bleeding/kg in the first 12 hours (39.1 versus 20.3 mL/kg) p = 0.016. Death occurred in 9 cases (31.03 %) versus one (5.6 %) in the SI group with p = 0.037; complications exclusive as acute renal failure, hemopneumothorax, pneumonia, permanent AV-block and multiple organ failure were observed. morbidity and mortality was higher in classical ventriculotomy group in comparison with SI. This is possibly associated with higher blood volume.

Surgical correction of frontoethmoidal meningoencephalocele, although rare, is still challenging to neurosurgeons and plastic reconstructive surgeons. It is fundamental to establish reliable and safe surgical techniques. The twenty-first century has brought great advances in medical technology, and the 3D models can mimic the correct tridimensional anatomical relation of a tissue organ or body part. They allow both tactile and spatial understanding of the lesion and organ involved. The 3D printing technology allows the preparation for specific surgery ahead of time, planning the surgical approach and developing plans to deal with uncommon and high-risk intraoperative scenarios. The present report describes a case of frontoethmoidal encephalocele, (nasofrontal subtype) of a 19-month-old girl, whose surgical correction was planned using 3D printing modeling. The 3D model allowed a detailed discussion of the aspects of the surgical approach by having tissues of different consistencies and resistances, and also predicting with millimetric precision the bilateral orbitotomy measurements. Moreover, it was a fundamental and valuable factor in the multidisciplinary preoperative discussion. This approach allowed reducing the time of surgery, accurately planning the location of the osteotomies and precontouring the osteosynthesis material. 3D models can be very helpful tools in planning complex craniofacial operative procedures.

Unprocessed real-time imaging of vitreoretinal surgical maneuvers using a microscope-integrated spectral-domain optical coherence tomography system.

2013-01-01

We have recently developed a microscope-integrated spectral-domain optical coherence tomography (MIOCT) device towards intrasurgical cross-sectional imaging of surgical maneuvers. In this report, we explore the capability of MIOCT to acquire real-time video imaging of vitreoretinal surgical maneuvers without post-processing modifications. Standard 3-port vitrectomy was performed in human during scheduled surgery as well as in cadaveric porcine eyes. MIOCT imaging of human subjects was performed in healthy normal volunteers and intraoperatively at a normal pause immediately following surgical manipulations, under an Institutional Review Board-approved protocol, with informed consent from all subjects. Video MIOCT imaging of live surgical manipulations was performed in cadaveric porcine eyes by carefully aligning B-scans with instrument orientation and movement. Inverted imaging was performed by lengthening of the reference arm to a position beyond the choroid. Unprocessed MIOCT imaging was successfully obtained in healthy human volunteers and in human patients undergoing surgery, with visualization of post-surgical changes in unprocessed single B-scans. Real-time, unprocessed MIOCT video imaging was successfully obtained in cadaveric porcine eyes during brushing of the retina with the Tano scraper, peeling of superficial retinal tissue with intraocular forceps, and separation of the posterior hyaloid face. Real-time inverted imaging enabled imaging without complex conjugate artifacts. MIOCT is capable of unprocessed imaging of the macula in human patients undergoing surgery and of unprocessed, real-time, video imaging of surgical maneuvers in model eyes. These capabilities represent an important step towards development of MIOCT for efficient, real-time imaging of manipulations during human surgery.

Presence of young children at home may moderate development of hot flashes during the menopausal transition.

This work aims to determine the role of child care in hot flashes. Broad differences in vasomotor symptom experience are observed among perimenopausal women across cultures. Women in cultures where contact with young children is common report significantly fewer and less severe hot flashes than women in cultures where older women spend less time around children. Could these differences be related to the presence of young children? We surveyed 117 healthy women undergoing prophylactic bilateral oophorectomy (removal of both ovaries to reduce the risk of gynecologic cancers). Participants provided demographic information, including pre-surgical operation menopause status and number of children (younger than 13 y, 13-17 y, and 18 y or older) living at home. They were surveyed for menopausal symptoms 2 weeks before surgical operation and at 2 months, 6 months, and 1 year after surgical operation. Women who were premenopausal at the time of surgical operation experienced a significant increase in vasomotor symptoms. Within this group, participants with young children at home reported significantly fewer vasomotor symptoms across time than did women who did not live with young children. Women who were already menopausal at the time of surgical operation who had young children at home reported more vasomotor symptoms before surgical operation than did those without young children; however, this effect did not remain significant across follow-ups. These findings suggest that interactions with young children may mitigate hot flashes in women undergoing surgical menopause. These findings may be used to counsel women who are considering prophylactic oophorectomy about the likelihood of menopausal symptoms.

To develop recommendations on the evaluation and management procedure in patients undergoing total knee replacement based on best evidence and the experience of a panel of experts. A multidisciplinary group of 12 experts was selected that defined the scope, users and the document parts. Three systematic reviews were performed in patients undergoing knee replacement: (i)efficacy and safety of fast-tracks; (ii)efficacy and safety of cognitive interventions in patients with catastrophic pain, and (iii) efficacy and safety of acute post-surgical pain management on post-surgical outcomes. A narrative review was conducted on the evaluation and management of pain sensitization, and about the efficacy and safety of pre-surgical physiotherapy. The experts generated the recommendations and explicative text. The level of agreement was evaluated in a multidisciplinary group of 85 experts with the Delphi technique. The level of evidence was established as well for each recommendation. A total of 20 recommendations were produced. An agreement higher than 80% was reached in all of them. We found the highest agreement on the need for a full discharge report, on providing proper information about the process and on following available guidelines. There is consensus among professionals involved in the management of patients undergoing total knee replacement, in that it is important to protocolize the replacement process, performing a proper, integrated and coordinated patient evaluation and follow-up, paying special attention to the surgical procedure and postoperative period.

Risk Factors for Postoperative Respiratory Mortality and Morbidity in Patients Undergoing Coronary Artery Bypass Grafting

PubMed Central

Rajaei, Samira; Dabbagh, Ali

2012-01-01

ABSTRACT Nowadays, coronary artery bypass grafting (CABG) is considered to be one of the most common surgical procedures. This procedure has been the main topic in many clinical research studies, which have assessed the effect of the procedure on patients’ outcomes. Like other surgical procedures, this procedure is also accompanied by a number of unwanted complications, including those of the respiratory system. Since the respiratory system plays an integral role in defining the clinical outcome of patients, improvements in studies that can assess and predict clinical outcomes of the respiratory system, assume greater importance. There are a number of predictive models which can assess patients in the preoperative period and introduce a number of risk factors, which could be considered as prognostic factors for patients undergoing CABG. The respiratory system is among the clinical systems that are assessed in many prediction scoring systems. This review assesses the main studies which have evaluated the possible risk factors for postoperative respiratory mortality and morbidity, in patients undergoing CABG. PMID:24223339

When undergo ambulatory surgical operations, the majority of patients experience high level of anxiety. Different experimental studies have shown that distraction techniques are effective in reducing pain and related anxiety. Since Virtual reality (VR) has been demonstrated a good distraction technique, it has been repeatedly used in hospital contexts for reducing pain in burned patients, but it has never been used during surgical operations. With the present randomized controlled study we intended to verify the effectiveness of VR in reducing anxiety in patients undergoing ambulatory operations under local or regional anaesthesia. In particular, we measured the degree to which anxiety associated with surgical intervention was reduced by distracting patients with immersive VR provided through a cell phone connected to an HMD compared to a no-distraction control condition. A significant reduction of anxiety was obtained after 45 minutes of operation in the VR group, but not in the control group and, after 90 minutes, the reduction was larger in the experimental group than in other one. In conclusion, this study presents an innovative promising technique to reduce anxiety during surgical interventions, even if more studies are necessary to investigate its effectiveness in other kinds of operations and in larger numbers of patients.

Background Quality in health care can be evaluated using quality indicators (QIs). Elements contained in the surgical operative report are potential sources for QI data, but little is known about the completeness of the narrative operative report (NR). We evaluated the completeness of the NR for patients undergoing a pancreaticoduodenectomy. Methods We reviewed NRs for patients undergoing a pancreaticoduodenectomy over a 1-year period. We extracted 79 variables related to patient and narrator characteristics, process of care measures, surgical technique and oncology-related outcomes by document analysis. Data were coded and evaluated for completeness. Results We analyzed 74 NRs. The median number of variables reported was 43.5 (range 13–54). Variables related to surgical technique were most complete. Process of care and oncology-related variables were often omitted. Completeness of the NR was associated with longer operative duration. Conclusion The NRs were often incomplete and of poor quality. Important elements, including process of care and oncology-related data, were frequently missing. Thus, the NR is an inadequate data source for QI. Development and use of alternative reporting methods, including standardized synoptic operative reports, should be encouraged to improve documentation of care and serve as a measure of quality of surgical care.

Positive vitreal pressure during phacoemulsification is a known risk factor for posterior capsule rupture. Knowledge of modifiable causes of positive vitreal pressure is imperative to aid in its management intraoperatively. The aim of our study was to determine whether the weight from the accumulation of a large volume of saline in the surgical drapes could have an effect on intraocular pressure in patients. Such an effect could indicate a source of posterior vitreal pressure in patients undergoing prolonged phacoemulsification. In 23 adult patients undergoing phacoemulsification at the Jones Eye Institute at the University of Arkansas for Medical Sciences, intraocular pressure readings were taken before and after the addition of 500 cc of saline to the surgical drapes and taken again after removal of the saline. Statistically significant differences in intraocular pressure were found between the baseline measurement, the measurement with saline, and the measurement after saline removal. No differences in the rise in intraocular pressure were found according to age, race, sex, or which eye was tested. Accumulation of a large volume of saline in surgical drapes has a modest effect on intraocular pressure. This may indicate a contributing cause of posterior vitreal pressure during prolonged phacoemulsification.

Objectives The tumour margin is an important surgical concept significantly affecting patient morbidity and mortality. We aimed in this prospective study to apply the microendoscope on tissue margins from patients undergoing surgery for oral cancer in vivo and ex vivo and compare it to the gold standard "paraffin wax", inter-observer agreement was measured; also to present the surgical pathologist with a practical guide to the every day use of the microendoscope both in the clinical and surgical fields. Materials and methods Forty patients undergoing resection of oral squamous cell carcinoma were recruited. The surgical margin was first marked by the operator followed by microendoscopic assessment. Biopsies were taken from areas suggestive of close or positive margins after microendoscopic examination. These histological samples were later scrutinized formally and the resection margins revisited accordingly when necessary. Results Using the microendoscope we report our experience in the determination of surgical margins at operation and later comparison with frozen section and paraffin section margins "gold standard". We were able to obtain a sensitivity of 95% and a specificity of 90%. Inter-observer Kappa scores comparing the microendoscope with formal histological analysis of normal and abnormal mucosa were 0.85. Conclusion The advantage of this technique is that a large area of mucosa can be sampled and any histomorphological changes can be visualized in real time allowing the operator to make important informed decisions with regards the intra-operative resection margin at the time of the surgery.

The Information Age and Hot Air.

PubMed

Austin, Paul N

2015-08-01

Forced-air warmers have been used for over twenty years to help prevent and treat inadvertent perioperative hypothermia. One result of hypothermia can be an increased risk of surgical site infection. Paradoxically, the question has been raised about the role of forced-air warmers in causing surgical site infections. A manufacturer of a competing device has been sending information directly to clinicians with warnings about using forced-air warmers with patients undergoing total joint arthroplasty. Three reviews have been published and none of these condemned the use of forced-air warmers in the operating room including with patients undergoing total joint arthroplasty. Clinicians must continue to seek information about this problem from peer-reviewed journals and not rely on interpretation by others such as manufacturers.

Could CCI or FBCI Fully Eliminate the Impact of Curve Flexibility When Evaluating the Surgery Outcome for Thoracic Curve Idiopathic Scoliosis Patient? A Retrospective Study

Purpose To clarify if CCI or FBCI could fully eliminate the influence of curve flexibility on the coronal correction rate. Methods We reviewed medical record of all thoracic curve AIS cases undergoing posterior spinal fusion with all pedicle screw systems from June 2011 to July 2013. Radiographical data was collected and calculated. Student t test, Pearson correlation analysis and linear regression analysis were used to analyze the data. Results 60 were included in this study. The mean age was 14.7y (10-18y) with 10 males (17%) and 50 females (83%). The average Risser sign was 2.7. The mean thoracic Cobb angle before operation was 51.9°. The mean bending Cobb angle was 27.6° and the mean fulcrum bending Cobb angle was 17.4°. The mean Cobb angle at 2 week after surgery was 16.3°. The Pearson correlation coefficient r between CCI and BFR was -0.856(P<0.001), and between FBCI and FFR was -0.728 (P<0.001). A modified FBCI (M-FBCI) = (CR-0.513)/BFR or a modified CCI (M-CCI) = (CR-0.279)/FFR was generated by curve estimation has no significant correlation with FFR (r=-0.08, p=0.950) or with BFR (r=0.123, p=0.349). Conclusions Fulcrum-bending radiographs may better predict the outcome of AIS coronal correction than bending radiographs in thoracic curveAIS patients. Neither CCI nor FBCI can fully eliminate the impact of curve flexibility on the outcome of correction. A modified CCI or FBCI can better evaluating the corrective effects of different surgical techniques or instruments. PMID:25984945

2015-02-01

The purpose of this study was to evaluate patients with adolescent idiopathic scoliosis (AIS) to determine whether a low body mass index (BMI) influences surgery outcomes and satisfaction. There were 39 patients in this prospective 3-year cohort study. The BMI, Cobb angle, the Body Shape Questionnaire 14 (BSQ-14), the Scoliosis Research Society Questionnaire 22 (SRS-22) and eight satisfaction questions results were obtained. Having a BMI greater than or less than 18 kg/m(2) was used as a determiner to allocate patients to groups. As a low BMI is related to the presence of a disturbance in body perception, patients were also dichotomized by using the BSQ-14. All scales were worse in both slimmer patients and the group with a body perception disorder. The group with a BMI <18 kg/m(2) obtained a total of 82.31 points in the SRS-22, and it was 93.45 points for the group with a BMI >18 kg/m(2) (p = 0.001). In terms of satisfaction, the percentage of patients that would undergo surgery again was 30.8 vs 69.2 % (p = 0.054). Patients with an alteration of physical perception obtained a total SRS-22 of 82.90 points versus 96.10 points in the control group (p < 0.001). No differences in terms of the Cobb correction (p = 0.29) or the percentage of correction (p = 0.841) were found in any case. The alteration of physical perception and a low BMI negatively affect the outcomes in AIS surgery, regardless of the curve magnitude and the percentage of correction. Considerable care should be taken in recommending surgical correction to these patients.

2013-05-01

Lateral column lengthening (LCL) has been shown to radiographically restore the medial longitudinal arch. However, the impact of LCL on foot function during gait has not been reported using validated clinical outcomes and gait analysis. Thirteen patients with a stage II flatfoot who had undergone unilateral LCL surgery and 13 matched control subjects completed self-reported pain and functional scales as well as a clinical examination. A custom force transducer was used to establish the maximum passive range of motion of first metatarsal dorsiflexion at 40 N of force. Foot kinematic data were collected during gait using 3-dimensional motion analysis techniques. Radiographic correction of the flatfoot was achieved in all cases. Despite this, most patients continued to report pain and dysfunction postoperatively. Participants post LCL demonstrated similar passive and active movement of the medial column when we compared the operated and the nonoperated sides. However, participants post LCL demonstrated significantly greater first metatarsal passive range of motion and first metatarsal dorsiflexion during gait than did controls (P < .01 for all pairwise comparisons). Patients undergoing LCL for correction of stage II adult-acquired flatfoot deformity experience mixed outcomes and similar foot kinematics as the uninvolved limb despite radiographic correction of deformity. These patients maintain a low arch posture similar to their uninvolved limb. The consequence is that first metatarsal movement operates at the end range of dorsiflexion and patients do not obtain full hindfoot inversion at push-off. Longitudinal data are necessary to make a more valid comparison of the effects of surgical correction measured using radiographs and dynamic foot posture during gait. Level III, comparative series.

The current and future role of magnetic resonance imaging in prostate cancer detection and management

2015-01-01

Purpose Accurate detection of clinically significant prostate cancer (PC) and correct risk attribution are essential to individually counsel men with PC. Multiparametric MRI (mpMRI) facilitates correct localization of index lesions within the prostate and MRI-targeted prostate biopsy (TPB) helps to avoid the shortcomings of conventional biopsy such as false-negative results or underdiagnosis of aggressive PC. In this review we summarize the different sequences of mpMRI, characterize the possibilities of incorporating MRI in the biopsy workflow and outline the performance of targeted and systematic cores in significant cancer detection. Furthermore, we outline the potential of MRI in patients undergoing active surveillance (AS) and in the pre-operative setting. Materials and methods An electronic MEDLINE/PubMed search up to February 2015 was performed. English language articles were reviewed for inclusion ability and data were extracted, analyzed and summarized. Results Targeted biopsies significantly outperform conventional systematic biopsies in the detection of significant PC and are not inferior when compared to transperineal saturation biopsies. MpMRI can detect index lesions in app. 90% of cases as compared to prostatectomy specimen. The diagnostic performance of biparametric MRI (T2w + DWI) is not inferior to mpMRI, offering options to diminish cost- and time-consumption. Since app 10% of significant lesions are still MRI-invisible, systematic cores seem to be necessary. In-bore biopsy and MRI/TRUS-fusion-guided biopsy tend to be superior techniques compared to cognitive fusion. In AS, mpMRI avoids underdetection of significant PC and confirms low-risk disease accurately. In higher-risk disease, pre-surgical MRI can change the clinically-based surgical plan in up to a third of cases. Conclusions mpMRI and targeted biopsies are able to detect significant PC accurately and mitigate insignificant PC detection. As long as the negative predictive value (NPV) is still imperfect, systematic cores should not be omitted for optimal staging of disease. The potential to correctly classify aggressiveness of disease in AS patients and to guide and plan prostatectomy is evolving. PMID:26816833

Excision and Patch Grafting of a Lateral Peyronie’s Plaque—Utilizing a Longitudinal “Window” Approach

PubMed Central

Lue, Kathy; Emtage, Justin B; Martinez, Daniel R; Yang, Christopher; Carrion, Rafael

2015-01-01

Introduction Peyronie’s disease (PD) is a debilitating disorder in which collagen deposition, fibrosis, and plaques in the tunica albuginea result in penile curvature, shortening, and pain. For severe curvatures requiring plaque incision or excision with grafting (PIEG), a subcoronal circumcising incision with penile degloving has historically been used. Aims The aim of this study was to report our unique approach to PIEG via a longitudinal “window” incision for the correction of PD, minimizing the surgical manipulation and dissection accompanying the traditional circumcising incisional approach that may lead to increased postoperative edema, pain, and prolonged healing time. Methods A patient presented with a stable, painless, 90-degree midshaft leftward curvature causing penetration difficulties and painful intercourse for his partner. His Sexual Health Inventory for Men (SHIM) score was 23. The patient opted for surgical correction with plaque excision and grafting via a 4-cm longitudinal incision overlying the point of maximal curvature along the left lateral penile shaft. This direct access to the left corpus cavernosum and plaque, along with dissecting skin, dartos, and Buck’s fascia, created a window with sufficient exposure for excision and patch grafting. Main Outcome Measures The main outcome measures were objective data and subjective data in men undergoing PIEG via lateral longitudinal “window” incision for PD repair. Results The plaque was excised and a porcine small intestinal submucosa graft was sewn in. Intraoperative artificial tumescence at the end of surgery revealed complete correction of the curvature. The patient experienced painless rigid erections by postoperative day three with minimal penile edema. By postoperative week four, he could successfully partake in coitus. His SHIM score remained unchanged. At maximum follow-up 6 months postoperatively, he still endorsed excellent cosmetic and functional outcomes with spontaneous unassisted erections and no recurrence of his curvature. Conclusion A lateral longitudinal incision for PIEG is a feasible technique and may reduce the postoperative morbidity and dissection required with traditional circumcising incision with penile degloving. Larger comparative studies are necessary for further evaluation. PMID:26185673

Long-Face Dentofacial Deformities: Occlusion and Facial Esthetic Surgical Outcomes.

Posnick, Jeffrey C; Liu, Samuel; Tremont, Timothy J

2018-06-01

The purpose of this study was to document malocclusion and facial dysmorphology in a series of patients with long face (LF) and chronic obstructive nasal breathing before treatment and the outcomes after bimaxillary orthognathic, osseous genioplasty, and intranasal surgery. A retrospective cohort study of patients with LF undergoing bimaxillary, chin, and intranasal (septoplasty and inferior turbinate reduction) surgery was implemented. Predictor variables were grouped into demographic, anatomic, operative, and longitudinal follow-up categories. Primary outcome variables were the initial postoperative occlusion achieved (T 2 ; 5 weeks after surgery) and the occulsion maintained long-term (>2 years after surgery). Six key occlusion parameters were assessed: overjet, overbite, coincidence of dental midlines, canine Angle classification, and molar vertical and transverse positions. The second outcome variable was the facial esthetic results. Photographs in 6 views were analyzed to document 7 facial contour characteristics. Seventy-eight patients met the inclusion criteria. Average age at surgery was 24 years (range, 13 to 54 yr). The study included 53 female patients (68%). Findings confirmed that occlusion after initial surgical healing (T 2 ) met the objectives for all parameters in 97% of patients (76 of 78). Most (68 of 78; 87%) maintained a favorable anterior and posterior occlusion for each parameter studied long-term (mean, 5 years 5 months). Facial contour deformities at presentation included prominent nose (63%), flat cheekbones (96%), flat midface (96%), weak chin (91%), obtuse neck-to-chin angle (56%), wide lip separation (95%), and excess maxillary dental show (99%). Correction of all pretreatment facial contour deformities was confirmed in 92% of patients after surgery. Long face patients with higher preoperative body mass index levels were more likely to have residual facial dysmorphology after surgery (P = .0009). Using orthognathic surgery techniques, patients with LF dentofacial deformity achieved the planned occlusion and most maintained the corrected occlusion long-term. In unoperated patients with LF, a "facial esthetic type" was identified. Orthognathic surgery proved effective in correcting associated facial dysmorphology in most patients.

To our knowledge, few studies have compared complications and surgical outcomes of adolescent idiopathic scoliosis (AIS) between junior attending surgeons and senior attending surgeons. To compare surgical strategies, complications, and outcomes of posterior corrective surgery for AIS between junior attending surgeons and senior attending surgeons. According to experience level of operation surgeons, the patients were assigned to 2 groups. Group A was the "junior surgeon" group. Group B was the "senior surgeon" group. The following parameters were compared between the 2 groups: age, sex, diagnosis, hospital of record, surgeon experience level, type of instrumentation, type of screws, estimated blood loss, duration of surgery, length of fusion, correction techniques, main curve correction, and thoracic kyphosis correction. A total of 132 patients with AIS were included in group A, whereas 207 were in group B. The translational technique was used more often in group A (P < 0.05). whereas the derotation technique was used more often in group B (P < 0.05). Senior surgeons used more monoaxial screws than junior surgeons (P < 0.05). The junior group had significantly greater estimated blood loss than the senior group (P < 0.05). The senior group had significant better correction rates of severe main curve (>70°) and thoracic kyphosis than the junior group (P < 0.05). Senior attending surgeons outperformed junior surgeons in blood loss control, thoracic kyphosis correction, and correction of severe curves. Copyright © 2018 Elsevier Inc. All rights reserved.

Late revision or correction of facial trauma-related soft-tissue deformities.

Surgical approaches used in accessing the facial skeleton for fracture repair are often the same as or similar to those used for cosmetic enhancement of the face. Rarely does facial trauma result in injuries that do not in some way affect the facial soft-tissue envelope either directly or as sequelae of the surgical repair. Knowledge of both skeletal and facial soft-tissue anatomy is paramount to successful clinical outcomes. Facial soft-tissue deformities can arise that require specific evaluation and management for correction. This article focuses on revision and correction of these soft-tissue-related injuries secondary to facial trauma. Copyright © 2013. Published by Elsevier Inc.

Repair of facial clefts implies wide tissue mobilization with multi-stage surgical treatment. Authors propose pre-surgical orthopedic correction for naso-oro-ocular clefts and a novel surgical option for Tessier No. 3 cleft. Two male infants, a Tessier No. 3 cleft (age 7 months) and another Tessier No. 4 (age 3 months), were treated with a modified orthopedic Latham device with additional septo-premaxillary molding and observed to age four years. Tessier No. 3 orthopedic measurements were obtained by image corrected cephalometric analysis. Subsequent repair included tissue expansion on Tessier No. 4 and naso-frontal Rieger flap combined with myocutaneous upper lid flap on Tessier No. 3. Orthopedic movements ranged from 18.5 mm in bi-planar to 33 mm in oblique analyses. Tissue margins became aligned with platform normalization. Tissue expansion on Tessier No. 4 improved distances from ala base-lower lid and subalar base-lip. The naso-frontal flap combined with myocutaneous upper lid flap on Tessier No. 3 had similar achievement, but also sufficiently lengthened ala base-canthal distance. Repairs were facilitated by pre-surgical orthopedic correction. The naso-frontal flap combined with an upper lid myocutaneous flap seems viable as a single-stage option to lengthen ala base-canthal distance to advance repair achievement in unilateral Tessier No. 3.

Why Do Patients Bleed?

PubMed Central

Curnow, Jennifer; Pasalic, Leonardo; Favaloro, Emmanuel J.

2016-01-01

Patients undergoing surgical procedures can bleed for a variety of reasons. Assuming that the surgical procedure has progressed well and that the surgeon can exclude surgical reasons for the unexpected bleeding, then the bleeding may be due to structural (anatomical) anomalies or disorders, recent drug intake, or disorders of hemostasis, which may be acquired or congenital. The current review aims to provide an overview of reasons that patients bleed in the perioperative setting, and it also provides guidance on how to screen for these conditions, through consideration of appropriate patient history and examination prior to surgical intervention, as well as guidance on investigating and managing the cause of unexpected bleeding.

Polythelia is a rare congenital malformation that occurs in 1–2% of the population. Intra-areolar polythelia is the presence of one or more supernumerary nipples located within the areola. This is extremely rare. This article presents 3 cases of intra-areolar polythelia treated at our Department. These cases did not present other associated malformation. Surgical correction was performed for psychological and cosmetic reasons using advancement flaps. The aesthetic and functional results were satisfactory. PMID:28331667

To study the evolution of deformity of the proximal interphalangeal joint over 5 years after good surgical correction of Dupuytren-induced contracture. We assessed 63 patients (72 fingers; 69 hands) with Dupuytren disease for the degree of contracture, its correction after surgery, and the range of movement at the proximal interphalangeal joints at 3 and 6 months, and 1, 3, and 5 years after fasciectomy with or without the use of a firebreak graft. We investigated associations between the recurrence of contracture and preoperative patient and surgical factors. There were 4 patterns of evolution of contracture after surgical correction. A total of 31 patients (33 hands) showed good improvement that was maintained for 5 years (minimal recontracture group). Twenty patients (23 hands) showed good initial improvement, which mildly worsened (< 20°) but was then maintained over 5 years (mild early recontracture group). Four patients (5 hands) worsened in first 3 months after surgery (> 20°) but there was no further worsening (severe early recontracture group). Eight patients (8 hands) worsened progressively over 5 years (progressive recontracture group). Worsening of contracture more than 6° between 3 and 6 months after surgery predicted progressive recontracture at 5 years. Recurrence of contracture (not disease recurrence) could be predicted as early as 6 months after surgery for Dupuytren disease. Copyright © 2013 American Society for Surgery of the Hand.

We sought to combine parental and child reports in order to describe the behavior, self-perception, and emotional profile of children with a surgically corrected congenital heart disease (CHD). Forty-three children with a surgically corrected CHD were selected and compared to an age- and sex-matched healthy group. The parents of the CHD children completed a behavior rating scale, the Child Behavior Checklist. Children 8 years and older (n = 23) completed a self-report questionnaire concerning perceived competence, their anxiety level, and feelings of depression. Compared to parents of healthy children, those of CHD children report significantly lower school results (p < .01), more school problems in general (p < .01), and a higher percentage of their children repeated a school year (p < .01). They also reported more social (p < .01) and attention problems (p < .01) and more aggressive behavior (p < .05). On self-perception and state anxiety questionnaires, no significant differences were found between the patient group and the healthy group. On a depression scale, however, children with a surgically corrected CHD reported more depressive feelings than healthy controls (p < .01). Parents of children with CHD rate their child's school competence to be weaker than healthy peers, they report more attention and social problems and more aggressive behavior. Children themselves did not report differences on perceived competence or anxiety but they do indicate more depressive symptoms than healthy peers.

Computer-aided surgical planner for a new bone deformity correction device using axis-angle representation.

PubMed

Wu, Ying Ying; Plakseychuk, Anton; Shimada, Kenji

2014-11-01

Current external fixators for distraction osteogenesis (DO) are unable to correct all types of deformities in the lower limb and are difficult to use because of the lack of a pre-surgical planning system. We propose a DO system that consists of a surgical planner and a new, easy-to-setup unilateral fixator that not only corrects all lower limb deformity, but also generates the contralateral/predefined bone shape. Conventionally, bulky constructs with six or more joints (six degrees of freedom, 6DOF) are needed to correct a 3D deformity. By applying the axis-angle representation, we can achieve that with a compact construct with only two joints (2DOF). The proposed system makes use of computer-aided design software and computational methods to plan and simulate the planned procedure. Results of our stress analysis suggest that the stiffness of our proposed fixator is comparable to that of the Orthofix unilateral external fixator. We tested the surgical system on a model of an adult deformed tibia and the resulting bone trajectory deviates from the target bone trajectory by 1.8mm, which is below our defined threshold error of 2mm. We also extracted the transformation matrix that defines the deformity from the bone model and simulated the planned procedure. Copyright © 2014 IPEM. Published by Elsevier Ltd. All rights reserved.

To evaluate the basic principles of surgical correction of concealed penis. From Jan. 1999 to Dec. 2002, 63 cases of concealed penis, aged from 1 year and 6 months to 19 years with a mean age of 7 years and 2 months, were corrected with two different approaches: 37 cases of group A with obesity were corrected by anchoring micrus tissue onto the pubis at the base of the penis, and 26 cases of group B by fixing the subcutateous tissues at both sides of the penile shaft to the deep tunica albuginea at the penile root. Then prepuce plasty was carried out. Six-month postoperative follow-up found adequate exposure of the penis in all of group A, prepuce oedema in 7 cases, abdomen fat liquidization in 3 cases, unsatisfactory recovery of incision hollow in 3 cases and patchy numbness of the glans in 1 case. The 25 cases of group B had satisfactory exposure of the penis, with no obvious prepuce oedema, 1 case with retraction of the penis 7 days after operation. Various surgical procedures could be adopted for concealed penis, and the key to the satisfactory appearance is the restoration of penile tunicae and the fixation at the base of the penis. Further study is needed to determine the natural history of these disorders as well as which conditions and what age will benefit most from surgical intervention.

Retropupillary iris-claw intraocular lens for the surgical correction of aphakia in cases with microspherophakia.

This study aimed to evaluate the safety and efficacy of retropupillary fixation of an iris-claw intraocular lens (IOL; Verisyse polymethyl methacrylate IOL, Abbott Medical Optics [AMO], Netherlands) for the surgical correction of aphakia in microspherophakic eyes without sufficient capsular support. This was a prospective, interventional, noncomparative case series. This interventional case series comprised 17 eyes of 9 microspherophakic patients. Retropupillary fixation of the Verisyse iris-claw IOL (AMO) was performed in all cases. The surgical time was measured. Corrected distance visual acuity, astigmatism, intraocular pressure (IOP), tissue reaction, pigment dispersion, and stability of the IOL were studied 1 day, 3 days, 1 week, 2 weeks, 1 month, and 6 months postoperatively. Eight patients had familial microspherophakia and one patient had Marfan's syndrome. Eighty-two percent of the cases achieved a visual acuity of 0.3 or better. There was no significant postoperative inflammatory reaction. Transient elevation of IOP was recorded in two cases in the 1st week only. One IOL developed disengagement of one of the haptics from the iris and was successfully re-engaged. All the other IOLs were well centered and stable. The mean surgical time was 18.0 ± 4.5 min. Retropupillary fixation of an iris-claw IOL is a safe and effective procedure that provides early visual recovery. It is also a time-saving method for correcting aphakia in microspherophakic eyes without sufficient capsular support.

1996-02-01

We studied all patients operated for partial anomalous pulmonary venous drainage and half-time follow-up. Twenty-eight patients with a mean age of 5 +/- 5 years (5 patients were less than 1 year old). There were sixteen male and twelve female patients. Thirteen patients were symptomatic (47%). The drainage was to the superior vena cava in thirteen cases, to the inferior vena cava in eight cases, to the right atrium in five cases, mixed (to the superior vena cava and to the inferior vena cava) in one case and to the innominate vein in one patient. The diagnosis was made through echocardiography and catheterization in 25 patients, whereas nuclear magnetic resonance was performed in the last five patients. All cases were corrected through medium thoracotomy, except for the single case in which the drainage was to the innominate vein). In 27 patients, the pulmonary veins were guided to the left atrium through an enlarged present atrial septal defect or through a created atrial septal defect. In one case a direct connection was performed from the veins to the left atrium. After the surgical correction, all patients underwent a color-coded Doppler echocardiography study and a nuclear magnetic resonance study was performed in five patients. Twenty-seven patients survived after surgical correction. The patient with a mixed drainage developed an obstruction of the superior vena cava, the pressure gradient was 9 mmHg. He required a second surgical procedure followed with angioplasty on two occasions during a six month period. Two patients showed an ectopic atrial rhythm at some late time. The patient who died was one month old and had an associated pulmonary parenchymal sequestration. Partial anomalous venous connection is a congenital heart disease which has an easy surgical correction. Complications may arise after the surgical correction, among them obstruction of the superior vena cava and arrythmias are most frequently found. Obstruction is present when 50% of the caval area is occupied by the patch. The arrythmias occur following all surgical techniques. In order to decrease the arrythmias it is necessary to perform a good hemosthasis at the site of the patch, to leave the sinus node free of compression and to perform the atrial incision at the posterior wall. The diagnosis and the follow-up can be performed with non-invasive procedures.

This study aims to describe the magnitude of hospital costs among patients undergoing elective colectomy, cholecystectomy, and pancreatectomy, determine whether these costs relate as expected to duration of care, patient case-mix severity and comorbidities, and whether risk-adjusted costs vary significantly by hospital. Correctly estimating the cost of production of surgical care may help decision makers design mechanisms to improve the efficiency of surgical care. Patient data from 202 hospitals in the ACS-NSQIP were linked to Medicare inpatient claims. Patient charges were mapped to cost center cost-to-charge ratios in the Medicare cost reports to estimate costs. The association of patient case-mix severity and comorbidities with cost was analyzed using mixed effects multivariate regression. Cost variation among hospitals was quantified by estimating risk-adjusted hospital cost ratios and 95% confidence intervals from the mixed effects multivariate regression. There were 21,923 patients from 202 hospitals who underwent an elective colectomy (n = 13,945), cholecystectomy (n = 5,569), or pancreatectomy (n = 2,409). Median cost was lowest for cholecystectomy ($15,651) and highest for pancreatectomy ($37,745). Room and board costs accounted for the largest proportion (49%) of costs and were correlated with length of stay, R = 0.89, p < 0.001. The patient case-mix severity and comorbidity variables most associated with cost were American Society of Anesthesiologists (ASA) class IV (estimate 1.72, 95% CI 1.57 to 1.87) and fully dependent functional status (estimate 1.63, 95% CI 1.53 to 1.74). After risk-adjustment, 66 hospitals had significantly lower costs than the average hospital and 57 hospitals had significantly higher costs. The hospital costs estimates appear to be consistent with clinical expectations of hospital resource use and differ significantly among 202 hospitals after risk-adjustment for preoperative patient characteristics and procedure type.

An increased lateral quadriceps vector has been associated with lateral patellar dislocation. Surgical correction of this increased vector through tibial tubercle medialization is often recommended when the quadriceps vector is "excessive". This can be evaluated by physical examination measurements of Q-angle and/or tubercle sulcus angle (TSA), as well as the magnetic resonance imaging (MRI) measurement of tibial tubercle-trochlear groove (TT-TG) distance. This study examined the relationship between three objective measurements of lateral quadriceps vector (TT-TG, Q-angle, TSA). A secondary goal was to relate lateral patellar tilt to these measurements. Consecutive patients undergoing patellofemoral stabilization surgery from 9/2010 to 6/2011 were included. The Q-angle and TSA were measured on intra-operative physical examination. The TT-TG and patellar tilt were measured on MRI. TSA, Q-angle, and patellar tilt were compared to TT-TG using Pearson correlation coefficient. The study cohort included 49 patients, ages 12-37 (mean 23.2); 62% female. The Pearson correlation coefficients showed (+) significance (p < 0.01) between the TT-TG and both TSA and Q-angle. Tilt and TT-TG were (+) non-significantly correlated. Despite positive correlations of each measurement with TT-TG, there is not uniform intra-patient correlation. In other words, if TT-TG is elevated for a patient, it does not guarantee that all other measurements, including tilt, are elevated in that individual patient. The TT-TG distance has significant positive correlation with the measurements of TSA and Q-angle in patients undergoing surgery for patellofemoral instability. The clinical relevance is that the variability within individual patients demonstrates the need for considering both TSA and TT-TG before and during surgical intervention to avoid overcorrection with a medial tibial tubercle osteotomy.

Thyroid eye disease (TED) is an autoimmune condition with an unpredictable course that may lead to permanent facial disfigurement. Eyelid retraction is one of the most common findings, and frequently demands attention due to ocular exposure and impaired cosmesis. Surgical treatment remains the most effective option, but there is a role for temporary corrections during the active phase of the disease, as well as in patients who are poor surgical candidates. The aim of this review is to describe the non-surgical modalities currently available for treatment of eyelid malposition in TED. The authors have focused on the use of hyaluronic acid, triamcinolone injections and botulinum toxin type A as non-surgical treatment alternatives, paying special attention to dosing, technique, efficacy and duration of effect. Non-surgical treatment modalities may represent viable in cases where surgical correction is not an option. Although temporary, these modalities appear to be beneficial for ocular exposure remediation, improving quality of life and broadening our therapeutic arsenal. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Post-Surgical Pain, Physical Activity and Satisfaction with the Decision to Undergo Hernia Surgery: A Prospective Qualitative Investigation

PubMed Central

Powell, Rachael; McKee, Lorna; King, Peter M.; Bruce, Julie

2013-01-01

Surgical repair is a common treatment for inguinal hernias but a substantial number of patients experience chronic pain after surgery. As some patients are pain-free on presentation, it is important to investigate whether patients perceive the treatment to be beneficial. The present study used qualitative methods to explore experiences of pain, activity limitations and satisfaction with treatment as people underwent surgery and recovery. Twenty-nine semi-structured interviews were conducted. Seven participants were interviewed longitudinally: before surgery and two weeks and four months post-surgery. Ten further participants with residual pain four months post-surgery were interviewed once. Semi-structured interviews included experience and perception of pain; activity limitations; reasons for having surgery; satisfaction with the decision to undergo surgery. A thematic analysis was conducted. Pain did not cause concern when perceived as part of the usual surgery and recovery processes. Activity was limited to avoid damage to the hernia site rather than to avoid pain. None of the participants reported dissatisfaction with the decision to have surgery; reducing the risk of life-threatening complications associated with untreated hernias was considered important. These findings suggest that people regarded surgical treatment as worthwhile, despite chronic post-surgical pain. Further research should ascertain whether patients are aware of the actual risk of complications associated with conservative rather than surgical management of inguinal hernia. PMID:26973903

Umbilical hernias present commonly during pregnancy secondary to increased intra-abdominal pressure. As a result, umbilical hernia incarceration or strangulation may affect pregnant females. The purpose of this study is to detail the operative management and 30-day outcomes of umbilical hernias in pregnant patients using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). All female patients undergoing umbilical hernia repair during pregnancy were identified within the ACS-NSQIP. Preoperative patient variables, intraoperative variables, and 30-day patient morbidity and mortality outcomes were investigated using a variety of statistical tests. A total of 126 pregnant patients underwent umbilical hernia repair from 2005 to 2014; 73 (58%) had incarceration or strangulation at the time of surgical intervention. The majority of patients (95%) underwent open umbilical hernia repair. Superficial surgical site infection was the most common morbidity in patients undergoing open umbilical hernia repair. Based on review of the ACS-NSQIP database, the incidence of umbilical hernia repair during pregnancy is very low; however, the majority of patients required repair for incarceration of strangulation. When symptoms develop, these hernias can be repaired with minimal 30-day morbidity to the mother. Additional studies are needed to determine the long-term recurrence rate of umbilical hernia repairs performed in pregnant patients and the effects of surgical intervention and approach on the fetus.

Voice tuning with new instruments for type II thyroplasty in the treatment of adductor spasmodic dysphonia.

2016-10-01

Adductor spasmodic dysphonia is a rare voice disorder characterized by strained and strangled voice quality with intermittent phonatory breaks and adductory vocal fold spasms. Type II thyroplasty differs from previous treatments in that this surgery does not involve any surgical intervention into the laryngeal muscle, nerve or vocal folds. Type II thyroplasty intervenes in the thyroid cartilage, which is unrelated to the lesion. This procedure, conducted with the aim of achieving lateralization of the vocal folds, requires utmost surgical caution due to the extreme delicacy of the surgical site, critically sensitive adjustment, and difficult procedures to maintain the incised cartilages at a correct position. During surgery, the correct separation of the incised cartilage edges with voice monitoring is the most important factor determining surgical success and patient satisfaction. We designed new surgical instruments: a thyroid cartilage elevator for undermining the thyroid cartilage, and spacer devices to gauge width while performing voice monitoring. These devices were designed to prevent surgical complications, and to aid in selecting the optimal size of titanium bridges while temporally maintaining a separation during voice monitoring. We designed new surgical instruments, including a thyroid cartilage elevator and spacer devices. Precise surgical procedures and performing voice tuning during surgery with the optimal separation width of the thyroid cartilage are key points for surgical success. We introduce the technique of voice tuning using these surgical tools in order to achieve a better outcome with minimal surgical complications. Copyright © 2016 Elsevier Ireland Ltd.

Congenital kyphoscoliosis is a disorder that often requires surgical treatment. Although many methods of surgical treatment exist, posterior-only vertebral column resection with instrumentation and fusion seem to have become the gold standard for very severe and very rigid curves. Multiple chevron and concave rib osteotomies have been previously reported to be effective in the treatment of neglected severe idiopathic curves. We hypothesized that this method may also be used successfully in the treatment of congenital kyphoscoliosis. To evaluate the effectiveness and safety of multiple chevron osteotomies combined with concave rib osteotomy and posterior pedicle screw instrumentation. Retrospective chart review in the spine service of a large university hospital. Adolescent patients undergoing a specific surgical treatment for the indication of rigid congenital kyphoscoliotic deformity. Radiographic images were used for the measurement of deformity correction. The Turkish version of the Scoliosis Research Society 22 (SRS-22) Patient Questionnaire has been used as a clinical outcome measure in the patient population. A retrospective chart review was performed. Patients admitted to Hacettepe Hospital Spine Center during the period of 2005 to 2009 were included. Criteria for inclusion were as follows: adolescent age group (10-16 years); congenital kyphoscoliosis; formation and/or segmentation defect of at least two vertebral motion segments; surgical treatment of deformity by posterior all-pedicle screw instrumentation, multiple chevron osteotomies, and multiple concave rib osteotomies; follow-up of at least 24 months; and a complete set of preoperative, postoperative, and follow-up standing posteroanterior and lateral full spinal radiographs. The patients' hospital records and X-rays were reviewed. Duration of surgery, intraoperative blood loss, postoperative transfusion requirements, postoperative stay in postanesthesia care unit (PACU), time of hospitalization, and complications were recorded. Deformity in both coronal and sagittal planes was analyzed for correction and maintenance of the correction in preoperative, postoperative, and follow-up radiographs. Patients' health-related quality of life was assessed using the SRS-22 questionnaire at the final follow-up. Eighteen patients met the inclusion criteria. Their average age was 13.6 years (range, 11-16 years). Chevron osteotomies were performed at apical segments (three to seven levels) and concave rib osteotomies at Cobb-to-Cobb (five to eight levels). No patient had preoperative cord compression because of the sharply angulated deformity or neurologic deficit. The average preoperative scoliosis was 66.0° (range, 31°-116°), 52.4° (range, 22°-85°) on flexibility X-rays, and became 24.9° (range, 12°-52°) postoperatively. The average preoperative global kyphosis (T2-T12) of 75.9° (range, 50°-106°) became 49.5° (range, 18°-66°). The average preoperative local kyphosis of 71.9° (range, 35°-114°) became 31.4° (range, -44° to 64°). The average intraoperative bleeding was 989 cc, surgical time was 292 minutes, and intraoperative transfusion was 2.3 units. The maximum PACU stay was overnight. There were no neurologic complications except one pneumothorax and one pneumonia. The average follow-up was 34.3 months. At follow-up, average scoliosis was 27.5° (range, 10°-50°), global kyphosis was 50.3° (range, 28°-73°), and local kyphosis was 36.9°(range, -36° to 58°). Performed on the last follow-up, the average scores for the five domains of SRS-22 were 4.3, 4.4, 4.2, 4.1, and 4.8 for function, pain, self-image, mental health, satisfaction, and total, respectively. Multiple chevron and concave rib osteotomies with posterior instrumentation provide an acceptable rate of deformity correction and maintenance of correction at 2 years with acceptable intraoperative bleeding, surgical time, postoperative morbidity, and rate of complications. It can be considered as an alternative in the treatment of rigid congenital curves involving more than three levels or multiple curves separated by at least two segments that would otherwise require multiple vertebral resections.

Surgical treatment for severe circumferentially fixed cervical kyphosis has been challenging. Both anterior and posterior releases are necessary to provide the cervical mobility necessary for fusion in a corrected position. In two case reports, we describe the circumferential osteotomy of anterior-posterior-anterior surgical sequence, and the efficacy of this technique when cervical pedicle screw fixation for severe fixed cervical kyphosis is used. Etiology of fixed cervical kyphosis was unknown in one patient and neurofibromatosis in one patient. Both patients had severe fixed cervical kyphosis as determined by cervical radiographs and underwent circumferential osteotomy and fixation via an anterior-posterior-anterior surgical sequence and correction of kyphosis by pedicle screw fixation. Severe fixed cervical kyphosis was treated successfully by the use of circumferential osteotomy and pedicle screw fixation. The surgical sequence described in this report is a reasonable approach for severe circumferentially fixed cervical kyphosis and short segment fixation can be achieved using pedicle screws.

To assess the efficiency and treatment outcome of patients treated with corticotomy-assisted en-masse orthodontic retraction as compared with the en-masse retraction without corticotomy. Forty adult patients with bimaxillary protrusion requiring correction of bidental proclination constituted the sample. The study group consisted of 22 patients (male 11, female 11) willing to undergo surgery to reduce the duration of their orthodontic treatment and 18 patients (male 9, female 9) desirous of undergoing conventional orthodontic treatment without surgical intervention constituted the control group. Comparison of rate of retraction and anchor loss between the study and the control group was assessed. Average rate of space closure of 1.8 mm/month in the maxilla and 1.57 mm/month in the mandible was observed in the study group compared to 1.02 mm/month in the maxilla and 0.87 mm/month in the mandible in the control group. The rate of retraction accelerated during the first 2 months of retraction. Molar anchor loss of approximately 0.6 mm occurred in the study group, and 1.8 mm occurred in the control group during the 4 months. The rate of retraction with study group was twice as faster when compared to the control group, accelerating during the first 2 months of retraction. There was better anchorage control with the undecorticated molar segment during the retraction period but was found to increase as time advanced.

Pelvic organ prolapse affects approximately 8% of women, and the demand for pelvic organ prolapse surgery is expected to increase by nearly 50% over the next 40 years. The surgical techniques used to correct pelvic organ prolapse have evolved over the last 10 years, with multiple well-designed studies addressing the risks, outcomes, reoperation rates, and optimal surgical approaches. Here we review the most recent evidence on the route of access, concomitant procedures, and synthetic materials for augmenting the repair. Ultimately, this review highlights that there is no optimal method for correcting pelvic organ prolapse and that the risks, benefits, and approaches should be discussed in a patient-centered, goal-oriented approach to decision-making.

The association of tetralogy of Fallot with atrial isomerism has been rarely reported. Eight cases (five with left isomerism and three with right isomerism) are known. This paper reports two other cases of tetralogy of Fallot with left atrial isomerism. The syndrome's defects were disguised and without clinical expression because of the presence of the right ventricular outlet obstruction of tetralogy of Fallot. These diagnostic elements, not recognized in one of the patients previous to surgical correction of tetralogy of Fallot, were present: junctional rhythm, bronchial isomerism, partial anomalous pulmonary vein connection, agenesy of inferior vena cava and abdominal heterotaxy; their identification previous to surgical correction of tetralogy of Fallot, is necessary for an adequate surgical management.

Boston keratoprosthesis (KPro) type I is a technique to treat patients with corneal diseases that are not amenable to conventional keratoplasty. Correct assembly and central implantation of the prosthesis are crucial for postoperative visual recovery. This study investigates the potential benefit of intraoperative optical coherence tomography (OCT) to monitor KPro surgery. Retrospective case series are presented for two patients who underwent Boston KPro type I implantation. The surgery in both patients was monitored intraoperatively using a commercially available intraoperative OCT (iOCT) device mounted on a surgical microscope. Microscope-integrated intraoperative OCT was able to evaluate the correct assembly and implantation of the KPro. All parts of the prosthesis were visible, and interfaces between the corneal graft and titanium backplate or anterior optics were clearly depictable. Moreover, iOCT visualized a gap between the backplate and graft in one case, and in the other case, a gap between the anterior optic and graft. Neither gap was visible with a conventional surgical microscope. The gap between the anterior optic and the graft could easily be corrected. Microscope-integrated iOCT delivers enhanced information, adding to the normal surgical microscope view during KPro surgery. Correct assembly can be controlled as well as the correct placement of the Boston KPro into the anterior chamber.

Metastatic adrenocortical carcinoma (ACC) is rapidly fatal, with few options for treatment. Patients with metachronous recurrence may benefit from surgical resection. The survival benefit in patients with hematogenous metastasis at initial presentation is unknown. A review of all patients undergoing surgery (European Network for the Study of Adrenal Tumors) stage IV ACC between January 2000 and December 2012 from two referral centers was performed. Kaplan-Meier estimates were analyzed for disease-free and overall survival (OS). We identified 27 patients undergoing surgery for stage IV ACC. Metastases were present in the lung (19), liver (11), and brain (1). A complete resection (R0) was achieved in 11 patients. The median OS was improved in patients undergoing R0 versus R2 resection (860 vs. 390 days; p = 0.02). The 1- and 2-year OS was also improved in patients undergoing R0 versus R2 resection (69.9 %, 46.9 % vs. 53.0 %, 22.1 %; p = 0.02). Patients undergoing neoadjuvant therapy (eight patients) had a trend towards improved survival at 1, 2, and 5 years versus no neoadjuvant therapy (18 patients) [83.3 %, 62.5 %, 41.7 % vs. 56.8 %, 26.6 %, 8.9 %; p = 0.1]. Adjuvant therapy was associated with improved recurrence-free survival at 6 months and 1 year (67 %, 33 % vs. 40 %, 20 %; p = 0.04) but not improved OS (p = 0.63). Sex (p = 0.13), age (p = 0.95), and location of metastasis (lung, p = 0.51; liver, p = 0.67) did not correlate with OS after operative intervention. Symptoms of hormonal excess improved in 86 % of patients. Operative intervention, especially when an R0 resection can be achieved, following systemic therapy may improve outcomes, including OS, in select patients with stage IV ACC. Response to neoadjuvant chemotherapy may be of use in defining which patients may benefit from surgical intervention. Adjuvant therapy was associated with decreased recurrence but did not improve OS.

We have been developing an automated method to image lymphatic vessels both ex vivo and in vivo with optical coherence tomography (OCT), using their optical transparency. Our method compensates for the OCT signal attenuation for each A-scan in combination with the correction of the confocal function and sensitivity fall-off, enabling reliable thresholding of lymphatic vessels from the OCT scans. Morphological image processing with a segment-joining algorithm is also incorporated into the method to mitigate partial-volume artifacts, which are particularly evident with small lymphatic vessels. Our method is demonstrated for two different clinical application goals: the monitoring of conjunctival lymphatics for surgical guidance and assessment of glaucoma treatment; and the longitudinal monitoring of human burn scars undergoing laser ablation treatment. We present examples of OCT lymphangiography ex vivo on porcine conjunctivas and in vivo on human burn scars, showing the visualization of the lymphatic vessel network and their longitudinal changes due to treatment.

The tricuspid valve was virtually ignored for a long time in the past. However, significant tricuspid regurgitation (TR) often accompanies left-side heart valve pathology and does not always reverse with its correction. If left untreated, TR can progress and result in progressive right ventricular failure. Current guideline recommendations still hold minor differences. Nevertheless, there is a consensus to operate on patients with severe TR undergoing left-sided valve surgery (class I) or those with mild to moderate TR with a dilated annulus (≥40 or ≥21 mm 2 , Class IIa). However, in case of the primary TR, surgical options is limited by a relatively high risk of mortality and morbidity. For these patients, new percutaneous approaches are becoming available but no long-term data are still available. In this review, we provide a comprehensive overview of the epidemiological and pathophysiological aspects of TR, and the current and future directions of therapy. © 2017 American Heart Association, Inc.

The laser irradiation of cartilage results in a plastic deformation of the tissue allowing for the creation of new stable shapes. During photothermal stimulation, mechanically deformed cartilage undergoes a temperature dependent phase transition, which results in accelerated stress relaxation of the tissue matrix. Cartilage specimens thus reshaped can be used to recreate the underlying framework of structures in the head and neck. Optimization of this process has required an understanding of the biophysical processes accompanying reshaping and also determination of the laser dosimetry parameters, which maintain graft viability. Extensive in vitro, ex-vivo, and in vivo animal investigations, as well as human trials, have been conducted. This technology is now in use to correct septal deviations in an office-based setting. While the emphasis of clinical investigation has focused on septoplasty procedures, laser mediated cartilage reshaping may have application in surgical procedures involving the trachea, laryngeal framework, external ear, and nasal tip. Future directions for research and device design are discussed.

Patients with squamous-cell carcinoma of the head and neck (SCCHN) on palliative therapy usually have a bad prognosis and suffer from various symptoms. With increasing use of targeted agents in cancer patients at the end of life, the correct assignment of therapy-related symptoms becomes increasingly difficult as cancer-related symptoms usually increase as well. We report on 2 cases of patients with SCCHN who received multimodal treatment including palliative therapy with cetuximab. Both patients developed severe thoracic and cervicothoracic pain following treatment. In both cases, extensive paraspinal abscess formation proved to be the underlying cause. One patient was treated conservatively; the other one had to undergo surgical intervention. Awareness of multifaceted therapy-related complications is mandatory when patients receive multimodal treatment including targeted therapies. Unexplained pain syndromes in this context should raise suspicions concerning possible infectious complications and should lead to early use of magnetic resonance imaging. © 2018 S.

The aim of this review is to summarize data published on the use of perioperative hypnosis in patients undergoing breast cancer surgery (BCS). Indeed, the majority of BCS patients experience stress, anxiety, nausea, vomiting, and pain. Correct management of the perioperative period and surgical removal of the primary tumor are clearly essential but can affect patients on different levels and hence have a negative impact on oncological outcomes. This review examines the effect of clinical hypnosis performed during the perioperative period. Thanks to its specific properties and techniques allowing it to be used as complementary treatment preoperatively, hypnosis has an impact most notably on distress and postoperative pain. During surgery, hypnosis may be applied to limit immunosuppression, while, in the postoperative period, it can reduce pain, anxiety, and fatigue and improve wound healing. Moreover, hypnosis is inexpensive, an important consideration given current financial concerns in healthcare. Of course, large randomized prospective studies are now needed to confirm the observed advantages of hypnosis in the field of oncology. PMID:27635132

As the most suitable approach for preventing bisphosphonate-related osteonecrosis of the jaw (BRONJ) in patients undergoing surgical tooth extraction is still under discussion, the present study evaluates the incidence of BRONJ after surgical tooth extraction using a standardized surgical protocol in combination with an adjuvant perioperative treatment setting in patients who are at high-risk for developing BRONJ. High-risk patients were defined as patients who received intravenous bisphosphonate (BP) due to a malignant disease. All teeth were removed using a standardized surgical protocol. The perioperative adjuvant treatment included intravenous antibiotic prophylaxis starting at least 24 h before surgery, a gastric feeding tube and mouth rinses with chlorhexidine (0.12%) three times a day. In the follow-up period patients were examined every 4 weeks for the development of BRONJ. Minimum follow-up was 12 weeks. In 61 patients a total number of 184 teeth were removed from 102 separate extraction sites. In eight patients (13.1%) BRONJ developed during the follow-up. A higher risk for developing BRONJ was found in patients where an additional osteotomy was necessary (21.4% vs. 8.0%; p = 0.0577), especially for an osteotomy of the mandible (33.3% vs. 7.3%; p = 0.0268). Parameters including duration of intravenous antibiotic prophylaxis, the use of a gastric feeding tube and the duration of intravenous BP therapy showed no statistical impact on the development of BRONJ. Furthermore, patients currently undergoing intravenous BP therapy showed no higher risk for BRONJ compared with patients who have paused or completed their intravenous BP therapy (p = 0.4232). This study presents a protocol for surgical tooth extraction in high-risk BP patients in combination with a perioperative adjuvant treatment setting, which reduced the risk for postoperative BRONJ to a minimum. However, the risk for BRONJ increases significantly if an additional osteotomy is necessary, especially in the mandible. Copyright © 2015 European Association for Cranio-Maxillo-Facial Surgery.

Diagnostic screening for Anderson-Fabry cardiomyopathy (AFC) is performed in the presence of specific clinical red flags in patients with hypertrophic cardiomyopathy (HCM) older than 25 years. However, left ventricular outflow tract obstruction (LVOTO) has been traditionally considered an exclusion criteria for AFC. To examine a series of patients diagnosed with HCM and severe basal LVOTO undergoing myectomy in whom the diagnosis of AFC was suspected by the cardiac surgeon intraoperatively and confirmed by histological and genetic examinations. This retrospective analysis of patients undergoing surgical septal reduction strategies was conducted in 3 European tertiary referral centers for HCM from July 2013 to December 2016. Patients with a clinical diagnosis of obstructive HCM referred for surgical management of LVOTO were observed for at least 18 months after the procedure (mean [SD] follow-up, 33 [14] months). Etiology of patients with HCM who underwent surgical myectomy. From 2013, 235 consecutive patients with a clinical diagnosis of HCM underwent septal myectomy. The cardiac surgeon suspected a storage disease in 3 patients (1.3%) while inspecting their heart samples extracted from myectomy. The mean (SD) age at diagnosis for these 3 patients was 42 (4) years; all were male. None of the 3 patients presented with extracardiac features suggestive of AFC. All patients showed asymmetrical left ventricular hypertrophy, with maximal left ventricular thickness in the basal septum (19-31 mm), severe basal LVOTO (70-120 mm Hg), and left atrial dilatation (44-57 mm). Only 1 patient presented with late gadolinium enhancement on cardiovascular magnetic resonance at the right ventricle insertion site. The mean (SD) age at surgical procedure was 63 (5) years. On tactile sensation, the surgeon felt a spongy consistency of the surgical samples, different from the usual stony-elastic consistency typical of classic HCM, and this prompted histological examinations. Histology showed evidence of intracellular storage, and genetic analysis confirmed a GLA A gene mutation (p.Asn215Ser) in all 3 patients. Screening for AFC should be performed even in the absence of red flags in patients with HCM older than 25 years.

This retrospective case control study aimed to evaluate the feasibility of using Estimation of Physiological Ability and Surgical Stress (E-PASS) and Physiological and Operative Severity Score for the enumeration of Mortality and Morbidity (POSSUM) systems in patients undergoing spinal surgical procedures. Degenerative spine disease has increased in incidence in aging societies, as has the number of older adult patients undergoing spinal surgery. Many older adults are at a high surgical risk because of comorbidity and poor general health. We retrospectively reviewed 217 patients who had undergone spinal surgery at a single tertiary care. We investigated complications within 1 month after surgery. Criteria for both skin incision in E-PASS and operation magnitude in the POSSUM system were modified to fit spine surgery. We calculated the E-PASS and POSSUM scores for enrolled patients, and investigated the relationship between postoperative complications and both surgical risk scoring systems. To reinforce the predictive ability of the E-PASS system, we adjusted equations and developed modified E-PASS systems. The overall complication rate for spinal surgery was 22.6%. Forty-nine patients experienced 58 postoperative complications. Nineteen major complications, including hematoma, deep infection, pleural effusion, progression of weakness, pulmonary edema, esophageal injury, myocardial infarction, pneumonia, reoperation, renal failure, sepsis, and death, occurred in 17 patients. The area under the receiver operating characteristic curve (AUC) for predicted postoperative complications after spine surgery was 0.588 for E-PASS and 0.721 for POSSUM. For predicted major postoperative complications, the AUC increased to 0.619 for E-PASS and 0.842 for POSSUM. The AUC of the E-PASS system increased from 0.588 to 0.694 with the Modified E-PASS equation. The POSSUM system may be more useful than the E-PASS system for estimating postoperative surgical risk in patients undergoing spine surgery. The preoperative risk scores of E-PASS and POSSUM can be useful for predicting postoperative major complications. To enhance the predictability of the scoring systems, using of modified equations based on spine surgery-specific factors may help ensure surgical outcomes and patient safety. Copyright © 2017.

Demographic changes strongly affect industrialized countries. While free tissue transfer was initially believed to be beneficial only for younger patients, there is an increasing number of elderly patients requiring microvascular operations in our aging society. Medical and surgical risks for head and neck cancer patients over a certain age who undergo free tissue transfer has hardly been investigated. A retrospective mono-center cohort study was performed. All patients with the age 75 or higher undergoing microvascular operations were reviewed. Patient characteristics including the ASA-status, the ACE-27-score, flap survival and postoperative medical and surgical complications were evaluated. The Clavien-Dindo-classification system for postoperative complications was applied to assess the severity of the complications. A total of 31 patients with an average age of 78.8 years were included. 4 patients suffered from venous congestion and had to undergo revision surgery. All flaps could successfully be salvaged. Higher ASA-status and ACE-score were significantly associated with postoperative medical and surgical complications and a higher severity of the complications. However , neither age nor operating time had influence on the complication rate. Microvascular free tissue transfer can be performed with a high degree of security in selected elderly patients. However, serious medical complications remain a concern, correlating strongly with high ASA and ACE-score. Careful patient selection is mandatory to reduce complications to a minimum.

(1) To assess the maintenance of drainage pathway patency in patients who undergo surgical management of cholesterol granulomas, (2) to review the histopathologic and radiologic changes associated with surgical drainage of petrous apex (PA) cholesterol granulomas, and (3) to provide histopathologic evidence regarding the exposed marrow theory of PA cholesterol granulomas. Retrospective case review and histopathologic analysis. Tertiary referral center. Records of 17 patients with surgically managed PA cholesterol granulomas were reviewed. Histopathologic analysis was performed on temporal bones of 11 patients with PA cholesterol granulomas from the Temporal Bone repository at the House Research Institute. Surgical drainage of PA cholesterol granulomas; follow-up radiologic imaging (computed tomography or magnetic resonance imaging), when available. Primary outcome is demonstrated maintenance of a PA outflow drainage pathway after the surgical drainage procedure as assessed by radiologic imaging, available histopathology, and/or recurrence of symptoms indicating failure of maintenance. Other measures include need for revision surgery and histopathology findings. A majority (65%) of patients exhibited maintenance of their PA drainage pathway. Histopathologic evidence suggests that the PA drainage pathway can be maintained for many years after surgical drainage. Recurrence of symptoms was related to obstruction of the drainage pathway by fibrous tissue and/or granulomatous tissue. Placement of a stent improved the patient's chance of remaining symptom-free, with recurrence of symptoms and revision surgery required in only 2 stent cases (18%) as compared with 83% of those with no stent (p ≤ 0.035). Histopathologic evidence for the exposed marrow theory of PA cholesterol granulomas was found. The majority of patients who undergo surgical drainage of PA cholesterol granulomas remain symptom-free after surgical drainage. Histopathologic analysis of temporal bone specimens provides evidence supporting the exposed marrow theory of PA cholesterol granuloma formation. Loss of patency of the PA drainage pathway may be an important predictor for symptomatic recurrence of PA cholesterol granulomas. Placement of a stent may decrease the likelihood of symptomatic recurrence.

Excimer and femtosecond lasers are widely used in ophthalmology to correct refraction. Laser systems for vision correction are based on versatile technical solutions and include multiple hard- and software components. Laser characteristics, properties of laser beam delivery system, algorithms for cornea treatment, and methods of pre-surgical diagnostics determine the surgical outcome. Here we describe the scientific and technological basis for laser systems for refractive surgery developed at the Physics Instrumentation Center (PIC) at the Prokhorov General Physics Institute (GPI), Russian Academy of Sciences.

The constricted ear may be described best as a pursestring closure of the ear. The deformity may include lidding of the upper pole with downward folding, protrusion of the concha, decreased vertical height, and low ear position relative to the face. The goals of surgical correction should include obtaining symmetry and correcting the intra-auricular anatomy. The degree of intervention is based on the severity of the deformity and may range from simple repositioning, soft tissue rearrangement, or manipulation of the cartilage. Multiple surgical techniques are described.

Introduction: Methylprednisolone (MP) is frequently preoperatively administered in children undergoing open heart surgery. The aim of this medication is to inhibit overshooting immune responses. Earlier studies demonstrated cellular and humoral immunological changes in pediatric patients undergoing heart surgeries with and without MP administration. Here in a retrospective study we investigated the modulation of the cellular immune response by MP. The aim was to identify suitable parameters characterizing MP effects by cluster analysis. Methods: Blood samples were analysed from two aged matched groups with surgical correction of septum defects. Group without MP treatment consisted of 10 patients; MP was administered on 21 patients (median dose: 11mg/kg) before cardiopulmonary bypass (CPB). EDTA anticoagulated blood was obtained 24 h preoperatively, after anesthesia, at CPB begin and end (CPB2), 4h, 24h, 48h after surgery, at discharge and at out-patient followup (8.2; 3.3-12.2 month after surgery; median and IQR). Flow cytometry showed the biggest MP relevant changes at CPB2 and 4h postoperatively. They were used for clustering analysis. Classification was made by discriminant analysis and cluster analysis by means of Genes@work software. Results & conclusion: 146 parameters were obtained from analysis. Cross-validation revealed several parameters being able to discriminate between MP groups and to identify immune modulation. MP administration resulted in a delayed activation of monocytes, increased ratio of neutrophils, reduced T-lymphocytes counts. Cluster analysis demonstrated that classification of patients is possible based on the identified cytomics parameters. Further investigation of these parameters might help to understand the MP effects in pediatric open heart surgery.

Mohs micrographic surgery (MMS) has a low rate of surgical site infection (SSI) without the use of prophylactic antibiotics. In the studies to date, there has been variation in the steps taken by each surgeon to prevent SSIs but in all cases sterile technique was used during wound reconstruction. We sought to evaluate the rate of SSIs among patients undergoing MMS with the use of clean surgical technique for all steps of MMS including wound reconstruction in the absence of prophylactic antibiotics. We prospectively evaluated 1000 patients undergoing MMS using clean surgical technique for SSIs. Clean surgical technique includes the use of clean surgical gloves and towels and a single pack of sterile instruments for all steps including wound reconstruction. There were 11 SSIs among 1000 patients with 1204 tumors, with an overall rate of infection of 0.91% (95% confidence interval 0.38%-1.45%). Three of the 11 infections were complications of hematomas. Four of the 11 infections occurred in flap closures, which had the highest rate of SSIs of 2.67% (4/150). The study was a prospective, single-institution uncontrolled study. To our knowledge, this is the first study to examine the rate of SSIs with the use of clean surgical technique, in the absence of antibiotic prophylaxis, for all steps of MMS including wound reconstruction. Our rate of SSIs of 0.91% is exceedingly low, underscoring the overall safety of MMS and its performance in the outpatient setting without the use of antibiotic prophylaxis or sterile technique.

To evaluate time trends in surgical resection rates and operative mortality in older adults diagnosed with locoregional pancreatic cancer and to determine the effect of age on surgical resection rates and 2-year survival after surgical resection. Retrospective cohort study using data from the Surveillance, Epidemiology, and End Results (SEER) and linked Medicare claims database (1992-2005). Secondary data analysis of population-based tumor registry and linked claims data. Medicare beneficiaries aged 66 and older diagnosed with locoregional pancreatic cancer (N=9,553), followed from date of diagnosis to time of death or censorship. Percentage of participants undergoing surgical resection, 30-day operative mortality after resection, and 2-year survival according to age group. Surgical resection rates increased significantly, from 20% in 1992 to 29% in 2005, whereas 30-day operative mortality rates decreased from 9% to 5%. After controlling for multiple factors, participants were less likely to be resected with older age. Resection was associated with lower hazard of death, regardless of age, with hazard ratios of 0.46, 0.51, 0.47, 0.43, and 0.35 for resected participants younger than 70, 70 to 74, 75 to 79, 80 to 84, and 85 and older respectively compared with unresected participants younger than 70 (P<.001). With older age, fewer people with pancreatic cancer undergo surgical resection, even after controlling for comorbidity and other factors. This study demonstrated increased resection rates over time in all age groups, along with lower surgical mortality rates. Despite previous reports of greater morbidity and mortality after pancreatic resection in older adults, the benefit of resection does not diminish with older age in selected people. © 2011, Copyright the Authors.

2015-02-01

The purpose of the paper was to present the results of surgical treatment of foot deformities in peripheral neuropathies using bone procedures: both joint preserving and with joint arthrodesis. The study included 26 patients, 14 males and 12 females (43 feet). The age of the patients at surgery ranged from 5 to 55 years (average 23 years). The follow-up ranged from 0.5 to 15 years (average 4.3 years). Seventeen patients presented Charcot-Marie-Tooth disease, three Friedreich's ataxia and six peripheral motor and sensory neuropathies of undetermined nature. Sixteen patients had bilateral procedures. Four patients had to be re-operated during the follow-up. The patients were divided into four groups depending on the age and the surgical technique applied. The groups I and II (9 children, 17 feet) included patients with growth plate still present in the foot just before surgery. In the groups III and IV (17 adults, 26 feet), bone growth was completed. The assessment of all patients based on a modified AOFAS scale ranged from 44 to 105 points (mean 83.7; SD 17.5). The assessment on the subjective scale ranged from 3 to 10 points (mean 7.4; SD 2.1). The assessment of quality of life on the WOMAC scale ranged from 0 to 41 points (mean 15.7; SD 13.2). All patients stated that they would decide to undergo the treatment again. For groups I and II, joint preserving surgeries gave better results; however, the results could not be statistically confirmed. The results for the groups III and IV were inconclusive as to which surgical techniques should be preferred, arthrodesis or joint preserving. The results show that none of the surgical techniques used for correction of foot deformities in motor-sensory polyneuropathies seems to be preferable.

Craniocerebral gunshot injuries (CGI) are increasingly encountered by neurosurgeons in civilian and urban settings. Unfortunately, more   prevalent condition in developing countries, with major armed conflicts which is still persisting, since the main trigger is violence at the national or state level. Management goals of CGI should focus on aggressive resuscitation and correction of coagulopathy; those with stable vital signs should undergo CT scan head at the earliest possible opportunity. Neuroimaging is vital for   planning of surgical management, especially to determine the type of surgery, routes of the approach to the surgical target area and  extraction of the impacted foreign bodies, however, surgical management is not always indicated. Although subset of such cases may be managed even with non-surgical management. The treatment comprises of immediate life salvaging resuscitative measures including control of the  persistent bleeding, care of associated injury, management of raised intracranial pressure, prevention of cerebrospinal fistula formation by primary watertight dural repair and  prevention of infection, through extensive debridement of contaminated, macerated or ischemic tissues; preservation of nervous tissue and restoration of anatomic structures through the hermetic sealing of dural and scalp defect. Recently, only few studies of craniocerebral penetrating injuries are published that too involving smaller patients sample sizes; although classic studies in the military and civil situation noticed associated relatively very high mortality and morbidity and psychological as well as economic impact on the   affected individual, the family and the health system in providing ongoing care to the sufferers and society at large.  Currently various measures are advocated with aim to reduce the incidence of CGI especially in civilian populations. It is highly necessary and immensely urgent to promote research in a neurocritical care of CGI to provide positive impact on improvement of  the quality of life and further providing better care and reduction of overall health care cost.

To characterize initial voice treatment selection following vocal fold mucosal resection in a Medicare population. Retrospective analysis of a large, nationally representative Medicare claims database. Patients with > 12 months of continuous Medicare coverage who underwent a leukoplakia- or cancer-related vocal fold mucosal resection (index) procedure during calendar years 2004 to 2009 were studied. The primary outcome of interest was receipt of initial voice treatment (thyroplasty, vocal fold injection, or speech therapy) following the index procedure. We evaluated the cumulative incidence of each postindex treatment type, treating the other treatment types as competing risks, and further evaluated postindex treatment utilization using the proportional hazards model for the subdistribution of a competing risk. Patient age, sex, and Medicaid eligibility were used as predictors. A total of 2,041 patients underwent 2,427 index procedures during the study period. In 14% of cases, an initial voice treatment event was identified. Women were significantly less likely to receive surgical or behavioral treatment compared to men. From age 65 to 75 years, the likelihood of undergoing surgical treatment increased significantly with each 5-year age increase; after age 75 years, the likelihood of undergoing either surgical or behavioral treatment decreased significantly every 5 years. Patients with low socioeconomic status were significantly less likely to undergo speech therapy. The majority of Medicare patients do not undergo voice treatment following vocal fold mucosal resection. Further, the treatments analyzed here appear disproportionally utilized based on patient sex, age, and socioeconomic status. Additional research is needed to determine whether these observations reflect clinically explainable differences or disparities in care. 2c.

The aim of this study was to analyze the prognostic value of TP53 mutations in a consecutive series of patients with hepatic metastases (HMs) from colorectal cancer undergoing surgical resection. Ninety-one patients with liver metastases from colorectal carcinoma were included. Mutational analysis of TP53, exons 4-10, was performed by single-strand conformation polymorphism and sequencing. P53 and P21 protein immunostaining was assessed. Multivariate Cox models were adjusted for gender, number of metastasis, resection margin, presence of TP53 mutations and chemotherapy treatment. Forty-six of 91 (50.05%) metastases showed mutations in TP53, observed mainly in exons 5-8, although 14.3% (n = 13) were located in exons 9 and 10. Forty percent (n = 22) were protein-truncating mutations. TP53 status associated with multiple (> or =3) metastases (65.6%, P = 0.033), advanced primary tumor Dukes' stage (P = 0.011) and younger age (<57 years old, P = 0.03). Presence of mutation associated with poor prognosis in univariate (P = 0.017) and multivariate Cox model [hazard ratio (HR) = 1.80, 95% confidence interval (CI) = 1.07-3.06, P = 0.028]. Prognostic value was maintained in patients undergoing radical resection (R0 series, n = 79, P = 0.014). Mutation associated with a worse outcome in chemotherapy-treated patients (HR = 2.54, 95% CI = 1.12-5.75, P = 0.026). The combination of > or =3 metastases and TP53 mutation identified a subset of patients with very poor prognosis (P = 0.009). P53 and P21 protein immunostaining did not show correlation with survival. TP53 mutational status seems to be an important prognostic factor in patients undergoing surgical resection of colorectal cancer HMs.

The association between marijuana use and surgical procedures is a matter of increasing societal relevance that has not been well studied in the literature. The primary aim of this study is to evaluate the relationship between marijuana use and in-hospital mortality, as well as to assess associated comorbidities in patients undergoing commonly billed orthopedic surgeries. The National Inpatient Sample (NIS) database from 2010 to 2014 was used to determine the odds ratios for the associations between marijuana use and in-hospital mortality, heart failure (HF), stroke, and cardiac disease (CD) in patients undergoing five common orthopedic procedures: hip (THA), knee (TKA), and shoulder arthroplasty (TSA), spinal fusion, and traumatic femur fracture fixation. Of 9,561,963 patients who underwent one of the five selected procedures in the four-year period, 26,416 (0.28%) were identified with a diagnosis of marijuana use disorder. In hip and knee arthroplasty patients, marijuana use was associated with decreased odds of mortality compared to no marijuana use (p<0.0001), and increased odds of HF (p = 0.018), stroke (p = 0.0068), and CD (p = 0.0123). Traumatic femur fixation patients had the highest prevalence of marijuana use (0.70%), which was associated with decreased odds of mortality (p = 0.0483), HF (p = 0.0076), and CD (p = 0.0003). For spinal fusions, marijuana use was associated with increased odds of stroke (p<0.0001) and CD (p<0.0001). Marijuana use in patients undergoing shoulder arthroplasty was associated with decreased odds of mortality (p<0.001) and stroke (p<0.001). In this study, marijuana use was associated with decreased mortality in patients undergoing THA, TKA, TSA and traumatic femur fixation, although the significance of these findings remains unclear. More research is needed to provide insight into these associations in a growing surgical population.

To evaluate the alterations on surgical outcomes after of the implementation of 3D laparoscopic technology for the surgical treatment of early-stage cervical carcinoma. Data of patients undergoing type B radical hysterectomy (with or without bilateral salpingo-oophorectomy) and pelvic lymphadenectomy via 3D laparoscopy were compared with a historical cohort of patients undergoing type B radical hysterectomy via conventional laparoscopy. Complications (within 60 days) were graded per the Accordion severity system. Data of 75 patients were studied: 15 (20%) and 60 (80%) patients undergoing surgery via 3D laparoscopy and conventional laparoscopy, respectively. Baseline patient characteristics as well as pathologic findings were similar between groups (p>0.1). Patients undergoing 3D laparoscopy experienced a trend toward shorter operative time than patients undergoing conventional laparoscopy (176.7 ± 74.6 vs 215.9 ± 61.6 minutes; p = 0.09). Similarly, patients undergoing 3D laparoscopic radical hysterectomy experienced shorter length of hospital stay (2 days, range 2-6, vs 4 days, range 3-11; p<0.001) in comparison to patients in the control group, while no difference in estimated blood loss was observed (p = 0.88). No between-group difference in complication rate was observed. 3D technology is a safe and effective way to perform type B radical hysterectomy and pelvic node dissection in early-stage cervical cancer. Further large prospective studies are warranted in order to assess the cost-effectiveness of the introduction of 3D technology in comparison to robotic assisted surgery.

Purpose Women who are newly diagnosed with breast cancer may consider contralateral prophylactic mastectomy (CPM) to reduce their future risk of cancer in their unaffected breast. Pre-surgical BRCA1/2 genetic testing can provide valuable risk information to guide this choice. However, little is understood about why BRCA1/2 mutation noncarriers, who are generally not at substantially elevated risk of contralateral disease, select CPM. Methods We examined the uptake of CPM among breast cancer patients identified as BRCA1/2 mutation noncarriers (n=92) as part of a larger prospective study of the impact of pre-surgical BRCA1/2 testing. Data obtained from self-report questionnaires and patient medical records were used to examine associations between theoretically-relevant background and psychosocial factors and BRCA1/2 mutation noncarriers’ decisions to undergo CPM. Results Among BRCA1/2 mutation noncarriers, 25% (n=23) elected to undergo CPM. Psychosocial factors including a self-reported physician recommendation for CPM, greater perceived contralateral breast cancer risk, and greater perceived benefits of CPM were all significantly associated with the uptake of CPM. Conclusions A sizeable minority of BRCA1/2 mutation noncarriers choose to undergo CPM after learning their mutation status through pre-surgical genetic testing. BRCA1/2 mutation noncarriers’ cognitive perceptions and social influences appear to be important in shaping their decisions regarding CPM. This work highlights the importance of several psychosocial factors in influencing patients’ surgical decisions. Future research is needed that examines the formation of BRCA1/2 mutation noncarriers’ beliefs regarding their disease and available treatment options, and that characterizes the physician-patient communication that occurs in this complex decision-making context.

Optimal perioperative antiplatelet therapy in patients with coronary stents undergoing surgery still remains poorly defined and a matter of debate among cardiologists, surgeons and anaesthesiologists. Surgery represents one of the most common reasons for premature antiplatelet therapy discontinuation, which is associated with a significant increase in mortality and major adverse cardiac events, in particular stent thrombosis. Clinical practice guidelines provide little support with regard to managing antiplatelet therapy in the perioperative phase in the case of patients with non-deferrable surgical interventions and/or high haemorrhagic risk. Moreover, a standard definition of ischaemic and haemorrhagic risk has never been determined. Finally, recommendations shared by cardiologists, surgeons and anaesthesiologists are lacking. The present consensus document provides practical recommendations on the perioperative management of antiplatelet therapy in patients with coronary stents undergoing surgery. Cardiologists, surgeons and anaesthesiologists have contributed equally to its creation. On the basis of clinical and angiographic data, the individual thrombotic risk has been defined. All surgical interventions have been classified according to their inherent haemorrhagic risk. A consensus on the optimal antiplatelet regimen in the perioperative phase has been reached on the basis of the ischaemic and haemorrhagic risk. Aspirin should be continued perioperatively in the majority of surgical operations, whereas dual antiplatelet therapy should not be withdrawn for surgery in the case of low bleeding risk. In selected patients at high risk for both bleeding and ischaemic events, when oral antiplatelet therapy withdrawal is required, perioperative treatment with short-acting intravenous glycoprotein IIb/IIIa inhibitors (tirofiban or eptifibatide) should be taken into consideration.

Women who are newly diagnosed with breast cancer may consider contralateral prophylactic mastectomy (CPM) to reduce their future risk of cancer in their unaffected breast. Pre-surgical BRCA1/2 genetic testing can provide valuable risk information to guide this choice. However, little is understood about why BRCA1/2 mutation noncarriers, who are generally not at substantially elevated risk of contralateral disease, select CPM. We examined the uptake of CPM among breast cancer patients identified as BRCA1/2 mutation noncarriers (n = 92) as part of a larger prospective study of the impact of pre-surgical BRCA1/2 testing. Data obtained from self-report questionnaires and patient medical records were used to examine associations between theoretically relevant background and psychosocial factors and BRCA1/2 mutation noncarriers' decisions to undergo CPM. Among BRCA1/2 mutation noncarriers, 25% (n = 23) elected to undergo CPM. Psychosocial factors including a self-reported physician recommendation for CPM, greater perceived contralateral breast cancer risk, and greater perceived benefits of CPM were all significantly associated with the uptake of CPM. A sizeable minority of BRCA1/2 mutation noncarriers choose to undergo CPM after learning their mutation status through pre-surgical genetic testing. BRCA1/2 mutation noncarriers' cognitive perceptions and social influences appear to be important in shaping their decisions regarding CPM. This work highlights the importance of several psychosocial factors in influencing patients' surgical decisions. Future research is needed that examines the formation of BRCA1/2 mutation noncarriers' beliefs regarding their disease and available treatment options, and that characterizes the physician-patient communication that occurs in this complex decision-making context.

Surgical excision of meningioma is often complicated by significant blood loss requiring blood transfusion with its attendant risks. Although tranexamic acid is used to reduce perioperative blood loss, its blood conservation effect is uncertain in neurosurgery. Sixty adults undergoing elective craniotomy for meningioma excision were randomized to receive either tranexamic acid or placebo, initiated prior to skin incision. Patients in the tranexamic acid group received intravenous bolus of 20mg/kg over 20min followed by an infusion of 1mg/kg/h till the conclusion of surgery. Intraoperative blood loss, transfusion requirements and estimation of surgical hemostasis using a 5-grade scale were noted. Postoperatively, the extent of tumor excision on CT scan and complications were observed. Demographics, tumor characteristics, amount of fluid infusion, and duration of surgery and anesthesia were comparable between the two groups. The amount of blood loss was significantly less in tranexamic acid group compared to placebo (830mlvs 1124ml; p=0.03). The transfusion requirement was less in tranexamic acid group (p>0.05). The patients in tranexamic acid group fared better on a 5-grade surgical hemostasis scale with more patients showing good hemostasis (p=0.007). There were no significant differences between the groups with regards to extent of tumor removal, perioperative complications, hospital stay or neurologic outcome. To conclude, administration of tranexamic acid significantly reduced blood loss in patients undergoing excision of meningioma. Fewer patients in the tranexamic acid group received blood transfusions. Surgical field hemostasis was better achieved in patients who received tranexamic acid. Copyright © 2017 Elsevier Ltd. All rights reserved.

[Comparison of posterior fossa decompression with and without duraplasty for surgical management for adult Chiari malformation type Ⅰ].

Objective: To evaluate and compare the efficacy between posterior fossa decompression without duraplasty (PFD) and posterior fossa decompression with duraplasty (PFDD) in the surgical management for adult Chiari Ⅰ malformation. Methods: Fifty-seven patients suffered from Chiari malformation type Ⅰ were treated in Department of Neurosurgery, Henan Provincial People's Hospital from August 2008 to October 2013. Twenty-three patients received posterior fossa decompression without duraplasty and the other 34 patients received posterior fossa decompression with duraplasty. The clinical results were retrospectively analyzed to compare the efficacy of two different surgical approaches. Results: There was no death or severe neurological dysfunction case in 57 patients of the two groups. Patients undergoing PFD had shorter length of hospital stay[(13.7±3.5) d vs (16.2±4.1) d, P <0.05]and surgical time[(98.7±22.1) min vs (132.3±39.6)min, P <0.05]. Cerebrospinal fluid-related complications and intracranial infection were more common in patients undergoing PFDD[(0/23, 0) vs (8/34, 23.5%), P <0.05]. Clinical improvement was comparable in two groups[(15/23, 65.2%) vs (26/34, 76.5%), P >0.05]at the one-year follow-up. The rate of syrinx regression in patients with Syringomyelia was higher in patients undergoing PFDD[(3/12, 25%) vs (17/22, 77.3%), P <0.05]. Conclusion: For adult patients with Chiari malformation type Ⅰ, PFD has the advantages of simple manipulation, short length of hospital stay and low incidence of cerebrospinal fluid-related complications and intracranial infection, compared with PFDD. It is comparable to PFDD in clinical improvement, but the effect of PFD is not as good as that of PFDD in the aspect of syrinx regression.

To assess anxiety level and factors contributing to its development in patients undergoing surgical treatment for breast cancer. The subjects of the study were 72 women, aged 20-80 years, with the diagnosis of primary breast cancer. The Basic Psycho-Oncological Documentation Scale (PO-BADO), the European Organization for Research, and the Treatment of Cancer Quality of Life Questionnaire and its Breast Cancer Module (EORTC QLQ-C30; BR-23), the Hospital Anxiety and Depression Scale (HADS) were used. The anxiety score showed negative correlation with EORTC QLQ-C30 'physical functioning', 'cognitive functioning', 'emotional functioning', 'global health status/quality of life' subscales (p≤0,002). Anxiety is a highly prevalent in women with breast cancer and has a marked negative impact, in particular on younger patients.

Effectiveness of the surgical safety checklist in correcting errors: a literature review applying Reason's Swiss cheese model.

Approximately 2,700 patients are harmed by wrong-site surgery each year. The World Health Organization created the surgical safety checklist to reduce the incidence of wrong-site surgery. A project team conducted a narrative review of the literature to determine the effectiveness of the surgical safety checklist in correcting and preventing errors in the OR. Team members used Swiss cheese model of error by Reason to analyze the findings. Analysis of results indicated the effectiveness of the surgical checklist in reducing the incidence of wrong-site surgeries and other medical errors; however, checklists alone will not prevent all errors. Successful implementation requires perioperative stakeholders to understand the nature of errors, recognize the complex dynamic between systems and individuals, and create a just culture that encourages a shared vision of patient safety.

In the surgical treatment of spinal dural arteriovenous fistulas (DAVFs), intraoperative definition of anatomic characteristics of the DAVF and identification of the fistulous point is mandatory to effectively exclude the DAVF. Intraoperative ultrasound and contrast-enhanced ultrasound integrated with color Doppler ultrasound was applied in the surgical setting for a cervical DAVF to identify the fistulous point and evaluate correct occlusion of the fistula. Integration of intraoperative ultrasound and contrast-enhanced ultrasound is a simple, cost-effective technique that provides an opportunity for real-time dynamic visualization of DAVF vascular patterns, identification of the fistulous point, and assessment of correct exclusion. Compared with other intraoperative tools, such as indocyanine green videoangiography, it allows the surgeon to visualize hidden anatomic and vascular structures, minimizing surgical manipulation and guiding the surgeon during resection.

Current surgical training is still highly dependent on expensive operating room (OR) experience. Although there have been many attempts to transfer more training to the skills laboratory, little research is focused on which technical behaviors can lead to the highest profit when they are trained outside the OR. The Pareto principle states that in any population that contributes to a common effect, a few account for the bulk of the effect. This principle has been widely used in business management to increase company profits. This study uses the Pareto principle for establishing content criteria for more efficient surgical training. A retrospective study was conducted to assess verbal guidance provided by 9 supervising surgeons to 12 trainees performing 64 laparoscopic cholecystectomies in the OR. The verbal corrections were documented, tallied, and clustered according to the aimed change in novice behavior. The corrections were rank ordered, and a cumulative distribution curve was used to calculate which corrections accounted for 80% of the total number of verbal corrections. In total, 253 different verbal corrections were uttered 1587 times and were categorized into 40 different clusters of aimed changes in novice behaviors. The 35 highest-ranking verbal corrections (14%) and the 11 highest-ranking clusters (28%) accounted for 80% of the total number of given verbal corrections. Following the Pareto principle, we were able to identify the aspects of trainee behavior that account for most corrections given by supervisors during a laparoscopic cholecystectomy on humans. This strategy can be used for the development of new training programs to prepare the trainee in advance for the challenges encountered in the clinical setting in an OR.

2012-11-01

The purpose of this study was to reconsider the factors influencing the remodeling effects in diaphyseal femoral fractures in children based on radiological results. We reviewed 39 patients with more than a 5° residual angulation deformity at the fracture site on anteroposterior and/or lateral views at the primary healing stage. The average follow-up period was 30.4 months. Angulation deformity was measured on plain radiographs both at the primary healing stage and the final follow-up. The correction rate (A - B/A × 100, A angulation deformities at the primary healing, B the angulation at the final follow-up) between at the primary healing stage and final follow-up was analyzed in terms of age at injury (0-5, 6-9, and ≥10 years), fracture site (proximal one third, middle one third, and distal one third) and direction of the deformities (coronal and sagittal planes). The remodeling effect significantly appeared on the coronal plane (correction rate 66.7 %) rather than on the sagittal plane (correction rate 31.6 %) in the 0- to 5-year age group (P < 0.05). There was a statistically significant difference in the correction rate between the 0- to 5-year age group (66.7 %) and the 6- to 9-year group (30.6 %) on the coronal plane (P < 0.05), with no significance between any other two groups on both planes. No statistical difference of remodeling effect appeared among the three fracture sites. The average leg-length discrepancy was 4.7 mm longer. We suggest that a patient ≤5 years at injury could expect more sufficient remodeling on the coronal plane compared with the other age groups on both planes. However, a patient >5 years at injury should be encouraged to undergo the maximum possible correction of the angulation deformity at the initial treatment. Surgical intervention might be considered for that purpose.

The ProSeal™ laryngeal mask airway (PLMA), i-gel™ and Laryngeal Tube Suction-D (LTS-D™) have previously been evaluated alone or in pair-wise comparisons but differing study designs make it difficult to compare the results. The aim of this study was to compare the clinical performance of these three devices in terms of efficacy and safety in patients receiving mechanical ventilation during elective surgical procedures. This prospective, randomised, double-blind study was conducted on 150 American Society of Anesthesiologists physical status I-II patients, randomly allocated into 3 groups, undergoing elective surgical procedures under general anaesthesia. PLMA, i-gel™ or LTS-D™ appropriate for weight or/and height was inserted. Primary outcome measured was airway sealing pressure. Insertion time, ease of insertion, number of attempts, overall success rate and the incidence of airway trauma and complications were also recorded. Intergroup differences were compared using one-way analysis of variance with post hoc correction for continuous data and Chi-square test for categorical variables. Overall success rate was comparable between the three devices (i-gel™ 100%, LTS-D™ 94%, PLMA 96%). Airway sealing pressure was lower with i-gel™ (23.38 ± 2.06 cm H 2 O) compared to LTS-D™ (26.06 ± 2.11 cm H 2 O) and PLMA (28.5 ± 2.8 cm H 2 O; P < 0.0005). The mean insertion time was significantly more in PLMA (38.77 ± 3.2 s) compared to i-gel™ (27.9 ± 2.53 s) and LTS-D™ (21.66 ± 2.31 s; P < 0.0005). Airway sealing pressure and insertion time were significantly higher in PLMA compared to i-gel™ and LTS-D™.

Results of the application of intraoperative mitomycin C in dacryocystorhinostomy.

2004-01-01

Dacryocystorhinostomy (DCR) is widely accepted as the procedure of choice for surgical correction of lacrimal drainage system obstruction distal to common canaliculus in adulthood. The success rate of DCR has been reported to be from 63% to 99%. DCR failure has been attributed to membranous occlusion of the rhinostomy site caused by soft tissue scarring. More recently, use of mitomycin C (MMC) has been described in lacrimal drainage surgery. The beneficial effect of MMC as a surgical adjunct is thought to be related to its potent inhibition of fibroblast proliferation. To improve the success rate of DCR, the authors used MMC as an adjunct to surgery in 130 patients with nasolacrimal duct obstruction undergoing lacrimal surgery. They were assigned randomly into a MMC DCR group and a regular DCR group (control group). The mean age of the MMC group was 40+/-15 years and that of the control group was 42+/-16 years. The standard surgical techniques of an external DCR were used in all patients of both groups. Patients were followed for 6 months. The authors evaluated the patients with subjective symptoms (improvement in tearing) and objective findings such as the height of tear meniscus, fluorescein dye test, and patency at the time of irrigation. There was no significant difference in the age between the two groups (p=1.00). Six patients in the mitomycin group were symptomatic after 6 months' follow-up; probe and irrigation showed non-patency of lacrimal system. The success rate in the MMC group was therefore 90.5% (59/65), and in the conventional group it was 92.4% (60/65). No significant difference between the two groups was present (p=0.75). The authors conclude that the use of intraoperative MMC in DCR surgery does not change the success rate of this procedure.

The aim of this study was to define the indicators predicting improved abdominal wall function after surgical repair of abdominal rectus diastasis (ARD). Preoperative subjective assessment quantified by the validated Ventral Hernia Pain Questionnaire (VHPQ) was related to relative postoperative functional improvement in abdominal muscle strength. Fifty-seven patients undergoing surgery for ARD completed the VHPQ before surgery. Preoperative pain assessment results were compared with the relative improvement in muscle strength measured with the BioDex system 4. There was a correlation between the relative improvement in muscle strength measured by the BioDex System 4 for flexion at 30 degrees (P = 0.046) and 60 degrees per second (P = 0.004) and the preoperative question, "Do you find it painful to sit for more than 30 minutes?" There was also a correlation between BioDex improvement for flexion at 30 degrees (P = 0.022) and for isometric work load (P = 0.038) and the preoperative question, "Has abdominal pain limited your ability to perform sports activities?" The VHPQ responses also formed a pattern with a fairly good correlation between other BioDex modalities (with the exception of extension at 60 degrees per second) and the response to the question regarding complaints when performing sports. Postoperative visual analog scale ratings of abdominal wall stability correlated to the questions regarding complaints when sitting (P = 0.040) and standing (P = 0.047). No other correlation was seen. VHPQ ratings concerning pain while being seated for more than 30 minutes and pain limiting the ability to perform sports are promising indicators in the identification of patients likely to benefit from surgical correction of their ARD.

The present study was designed to evaluate the role of intraoperative ultrasound (IOUS) in intrahepatic staging and the impact on surgical strategy for patients with colorectal liver metastases (CRLM). The study included 515 patients who had undergone liver resection for CRLM at two tertiary care referral centers. Data from a prospectively collected database were retrospectively analysed. Early intrahepatic recurrence was assessed at 3 and 6 months after resection and was considered as residual disease undetected by IOUS. Performance of imaging modalities was compared by analysis of studies on individual patients. A total of 1,370 liver metastases were detected preoperatively with a median of 3 imaging modalities. MRI and PET were performed in 51 and 42 % of the patients, respectively. Median number of days between last imaging and surgery was 18. Contrast-enhanced IOUS was performed in 136 patients (26.4 %). Intraoperatively, 293 new nodules were found in 132 patients: on histology 280 were CRLM (17.6 %). Surgical strategy was changed in 140 patients (27.2 %). On multivariate analysis synchronous and bilobar metastases ≥ 3 in number, BMI ≥ 30, and time between last imaging and surgery longer than 18 days resulted in predictive factors indicating new nodules detected by IOUS. Early intrahepatic recurrences were 3.7 and 7.9 % at 3 and 6 months. Performance of CT, MRI, FDG-PET, and intraoperative staging was compared: sensitivity was 63.6, 68.8, 53.6, and 92 % and specificity was 91, 92.3, 95.8, and 97.8 %, respectively The use of IOUS continues to be mandatory for correct staging of patients with CRLM undergoing liver resection.

Abdominal surgical site infections (SSI) cause substantial morbidity and mortality for patients undergoing operative procedures. We determined the incidence of and risk factors for SSI after abdominal surgery in the Department of Abdominal Surgery at the University Clinical Centre of Kosovo (UCCK). Prospective surveillance of patients undergoing abdominal surgery was performed between December 2005 and June 2006. CDC definitions were followed to detect SSI and study forms were based on Europe Link for Infection Control through Surveillance (HELICS) protocol. A total of 253 surgical interventions in 225 patients were evaluated. The median age of patients was 42 years and 55.1% of them were male. The overall incidence rate of SSI was 12%. Follow-up was achieved for 84.1% of the procedures. For patients with an SSI, the median duration of hospitalization was 9 days compared with 4 days for those without an SSI (p < 0.001). Surgical procedures were classified as emergent in 53.3% of cases. Superficial incisional SSI was most common (55%). Clinical infections were culture positive in 40.7% of cases. Duration of operation, duration of preoperative stay, wound class, ASA score > 2, use of antibiotic prophylaxis and NNIS class of > 2 were all significant at p < .001. The SSI rates for the NNIS System risk classes 0, 1 and 2-3 were 4.2%, 46.7% and 100%, respectively. SSI caused considerable morbidity among surgical patients in UCCK. Appropriate active surveillance and infection control measures should be introduced during preoperative, intra-operative, and postoperative care to reduce infection rates.

Background Patients undergoing coronary artery bypass grafting (CABG) must often see multiple providers dispersed across many care locations. To test whether “teamwork” (assessed with the bipartite clustering coefficient) among these physicians is a determinant of surgical outcomes, we examined national Medicare data from patients undergoing CABG. Methods and Results Among Medicare beneficiaries who underwent CABG between 2008 and 2011, we mapped relationships between all physicians who treated them during their surgical episodes, including both surgeons and nonsurgeons. After aggregating across CABG episodes in a year to construct the physician social networks serving each health system, we then assessed the level of physician teamwork in these networks with the bipartite clustering coefficient. Finally, we fit a series of multivariable regression models to evaluate associations between a health system’s teamwork level and its 60-day surgical outcomes. We observed substantial variation in the level of teamwork between health systems performing CABG (standard deviation for the bipartite clustering coefficient was 0.09). While health systems with high and low teamwork levels treated beneficiaries with comparable comorbidity scores, these health systems differed over several sociocultural and healthcare capacity factors (e.g., physician staff size, surgical caseload). After controlling for these differences, health systems with higher teamwork levels had significantly lower 60-day rates of emergency department visit, readmission, and mortality. Conclusions Health systems with physicians who tend to work together in tightly knit groups during CABG episodes realize better surgical outcomes. As such, delivery system reforms focused on building teamwork may have positive effects on surgical care. PMID:28263939

1975-03-01

A plastic surgical teaching service has been organized at a women's correctional institution to provide a previously unrecognized medical need and to serve a valuable educational function for our residents in training. A total of 177 surgical candidates demonstrating a wide range of reconstructive problems including tattoos, scars, keloids, neoplasms of the skin and hands, deformities of the face and breasts, and numerous disabilities of the hands were identified among 241 inmates requesting examination. Thus far, 116 operative procedures have been performed on 101 patients. Patient acceptance has been high, and the support of prison authorities has been enthusiastic. Persistent efforts to convince legislators of the wisdom of supporting this program financially have only been partially successful and will require further accumulation of sociologic data bearing on the rehabilitative potential of the detained patient with a correctable deformity. Meanwhile, residents in training gain maturity as they provide a very "private" type of service for what has traditionally been considered a very "public" population of patients.

A new technique for correction of simple congenital earlobe clefts: diametric hinge flaps method.

Qing, Yong; Cen, Ying; Xu, Xuewen; Chen, Junjie

2013-06-01

The earlobe plays an important part in the aesthetic appearance of the auricle. Congenital cleft earlobe may vary considerably in severity from a simple notching to extensive tissue deficiency. Most patients with cleft earlobe require surgical correction because of abnormal appearance. In this article, a new surgical technique for correcting congenital simple cleft earlobe using diametric hinge flaps is introduced. We retrospectively reviewed 4 patients diagnosed with congenital cleft earlobe between 2008 and 2010. All of them received this new surgical method. The patients were followed up from 3 to 6 months. All patients attained relatively full bodied earlobes with smooth contours, inconspicuous scars, and found their reconstructed earlobes to be aesthetically satisfactory. One patient experienced hypoesthesia in the area operated on, but recovered 3 months later. No other complications were noted. This simple method not only makes full use of the surrounding tissues to reconstruct full bodied earlobes but also avoids small notch formation caused by the linear scar contraction sometimes seen when using more traditional methods.

Autonomic nervous system function, child behavior, and maternal sensitivity in three-year-old children with surgically corrected transposition.

Explore relationships among autonomic nervous system (ANS) function, child behavior, and maternal sensitivity in three-year-old children with surgically corrected transposition of the great arteries (TGA) and in children healthy at birth. Children surviving complex congenital heart defects are at risk for behavior problems. ANS function is associated with behavior and with maternal sensitivity. Child ANS function (heart rate variability) and maternal sensitivity (Parent-Child Early Relational Assessment) were measured during a challenging task. Mother completed the Child Behavior Checklist. Data were analyzed descriptively and graphically. Children with TGA had less responsive autonomic function and more behavior problems than healthy children. Autonomic function improved with more maternal sensitivity. Alterations in ANS function may continue years after surgical correction in children with TGA, potentially impacting behavioral regulation. Maternal sensitivity may be associated with ANS function in this population. Continued research on relationships among ANS function, child behavior, and maternal sensitivity is warranted.

Plication procedures—excisional and incisional corporoplasty and imbrication for Peyronie’s disease

PubMed Central

Chen, Roger; McCraw, Casey

2016-01-01

Plication procedures for the correction of Peyronie’s disease (PD) curvature are management options for PD patients. There are basically three types of procedures: excisional corporoplasty, incisional corporoplasty, and plication-only. This review is a compilation of English literature, peer-reviewed, published articles addressing these types of operations for Peyronie’s curvature correction, not congenital curvature. According to the urology literature, this surgical type was initially used for correction of curvature associated with hypospadias repair or congenital penile curvature. The procedures also, for the most part, historically became an alternative for plaque excision and graft repair, because of the difficulty with such repairs and the often-resultant erectile dysfunction (ED). A brief section traces some of the origins of these various repairs, followed by a brief section on the selection criteria for these types of surgery for the patient with PD penile curvature. We also review the significant articles in which the three types were presented with modifications. Finally, several articles that compare the various surgical repairs are summarized in the order that they appear in the literature. These types of surgery have become a mainstay for the surgical correction of penile curvature due to PD. PMID:27298779

The advent of high-tech diagnostic methods raises concerns nowadays about the value of the clinical approach and bedside diagnosis. This at least is the impression given by modern scientific literature, which rarely even mentions this part of examination of the patient. In order to define the actual role played by auscultation in the management of cardiological patients by the primary care physician, the records of 250 patients consecutively referred to a cardiologist are analyzed. The practitioner's initial clinical diagnosis is compared to the final cardiological diagnosis. Per referred patient, 1.76 specialized consultations were needed. In 64% of the cases only one such consultation took place. Initial diagnosis was correct in 80% of all cases, partly correct in 11% and incorrect in 9% of the cases. Out of the 64 cases of valvular diseases, 33 were initially correctly recognized by the physician. The cardiological investigation was also invasive in 6.5% of all cases, 4.5% of the patients eventually undergoing invasive or surgical treatment. Thus the great majority of the patients (93.5%) were managed by the primary physician with "first-line" cardiologist's support, which was often only occasional (only one specialized consultation in about two thirds of all cases). This highly independent and presumably cost-effective patient management by the primary care physician implies a high level of clinical skill. It stresses the outstanding importance of continuing teaching of the clinical approach and particularly of cardiac auscultation, which is still the best screening method for valvular heart disease.

To develop and validate a partially automated algorithm to identify surgical site infections (SSIs) using commonly available electronic data to reduce manual chart review. Retrospective cohort study of patients undergoing specific surgical procedures over a 4-year period from 2007 through 2010 (algorithm development cohort) or over a 3-month period from January 2011 through March 2011 (algorithm validation cohort). A single academic safety-net hospital in a major metropolitan area. Patients undergoing at least 1 included surgical procedure during the study period. Procedures were identified in the National Healthcare Safety Network; SSIs were identified by manual chart review. Commonly available electronic data, including microbiologic, laboratory, and administrative data, were identified via a clinical data warehouse. Algorithms using combinations of these electronic variables were constructed and assessed for their ability to identify SSIs and reduce chart review. The most efficient algorithm identified in the development cohort combined microbiologic data with postoperative procedure and diagnosis codes. This algorithm resulted in 100% sensitivity and 85% specificity. Time savings from the algorithm was almost 600 person-hours of chart review. The algorithm demonstrated similar sensitivity on application to the validation cohort. A partially automated algorithm to identify potential SSIs was highly sensitive and dramatically reduced the amount of manual chart review required of infection control personnel during SSI surveillance.

To determine the efficacy of combined endoscopic medial and external lateral orbital decompression for the treatment of compressive optic neuropathy (CON) in thyroid eye disease (TED). A retrospective review of all patients undergoing combined surgical orbital decompression for CON between 2000 and 2010 was conducted. Fifty-nine eyes of 34 patients undergoing combined surgical orbital decompression for CON. Clinical outcome measures included visual acuity, Hardy-Rand-Rittler (HRR) colour plate testing, relative afferent pupillary defect, intraocular pressure measurement, and Hertel exophthalmometry. A CON score was calculated preoperatively and postoperatively based on the visual acuity and the missed HRR plates. A higher CON score correlates with more severe visual dysfunction. All patients had improvement of their optic neuropathy after surgical decompression. CON score was calculated for 54 eyes and decreased significantly from a mean of 13.2 ± 10.35 preoperatively to a mean of 8.51 ± 10.24 postoperatively (p < 0.0001). Optic neuropathy was completely resolved in 93.22% (55/59 eyes). Eighteen of 34 patients (52.94%) experienced development of new-onset postoperative strabismus that required subsequent surgical intervention. Endoscopic medial combined with external lateral orbital decompression is an effective technique for the treatment of TED-associated CON. © 2013 Canadian Ophthalmological Society Published by Canadian Ophthalmological Society All rights reserved.

Introduction: We analyze the outcomes of patients with urethral stricture who underwent surgical treatment within the past 5 years. Methods: This is a retrospective study of male patients who underwent surgery for urethral stricture at our service from January 2008 to June 2012. We analyzed the comorbidities, type, length and location of the stricture and the surgical treatment outcome after endoscopic urethrotomy, urethroplasty or both. Results: In total, 45 patients with a mean age of 53.7 ± 16.7 years underwent surgical treatment for urethral stricture. Six months after surgery, 46.7% of the patients had a maximum urinary flow greater than 15 mL/s, whereas 87.3% of the patients exhibited no stricture by urethrography after the treatment. The success rate in the patients undergoing urethrotomy was 47.8% versus 86.4% in those undergoing urethroplasty (p = 0.01). Twenty percent of the patients in whom the initial urethrotomy had failed subsequently underwent urethroplasty, thereby increasing the treatment success. Conclusion: In most cases, the treatment of choice for urethral stricture should be urethroplasty. Previous treatment with urethrotomy does not appear to produce adverse effects that affect the outcome of a urethroplasty if urethrotomy failed, so urethrotomy may be indicated in patients with short strictures or in patients at high surgical risk.

Moscardi, Paulo R. M.; Gosalbez, Rafael; Castellan, Miguel Alfedo

2017-01-01

Penile curvature is a frequent feature associated with hypospadias with also a great variability of severity among each patient. While the low-grade curvature (<30°) can be relatively easily corrected by simple techniques like penile degloving and dorsal plication, severe cases often demand more complex maneuvers to manage it. A great number of surgical techniques have been developed to adequately correct curvatures greater than 30°; however, each one of them should be individualized to different patients and local conditions encountered. In this article, we will review the evaluation of the pediatric patient with penile curvature associated with hypospadias with a special attention to high-grade cases, their management, indications for surgical treatment, and several surgical options for their definitive treatment.

The authors' primary objective was to test the hypothesis that Cerebral State Index (CSI)-guided control of anesthetic depth might reduce the consumption of anesthetics and shorten the duration of ICU and hospital stays after surgical correction of combined valve disorders. Single center, randomized trial. City Hospital Number 1 of Arkhangelsk, Russian Federation. Fifty adult patients with combined valve disorders requiring surgical correction. The patients were randomized into 2 groups. In the CSI group, anesthetic depth was monitored, and the rate of infusion of propofol was titrated to maintain the depth of anesthesia corresponding to a CSI of 40-60. In the control group, the depth of anesthesia was monitored clinically, and the dosage of propofol was administered according to the recommendations of the manufacturer. All patients received standard perioperative monitoring. Consumption of anesthetics and length of ICU and hospital stays were recorded. Preoperative patient characteristics did not differ significantly between the groups. In the CSI group, average intraoperative doses of midazolam and propofol were reduced by 41% and 19%, respectively (p<0.01). Maintenance of anesthesia guided by CSI shortened the time until fit for ICU discharge by 50% and reduced the lengths of ICU and postoperative hospital stays by 35% and 25%, respectively (p< 0.05). Monitoring of anesthetic depth reduces the requirements for midazolam and propofol, resulting in a faster recovery and a shorter postoperative ICU and hospital stay after surgical correction of combined valve disorders.

To reduce short-term complications of radical cystectomy (RC) and intestinal urinary diversion with vescica ileale Padovana (VIP) neobladder, we described and assessed an enhanced recovery protocol (ERP) in a series of consecutive patients. An ERP was introduced focusing on reduced bowel preparation, standardized feeding and analgesic regimens. We analyzed the outcomes with all patients consecutively undergoing RC and VIP neobladder who met the following inclusion criteria: American Society of Anesthesiologists score <3; absence of malnutrition according to the Mini Nutritional Assessment-Short Form criteria; absence of inflammatory bowel diseases. Thirty-one consecutive patients were recruited to undergo our ERP. Mean age of patients was 62.16 years. No patients died due to surgical complications. Nine of 31 patients experienced complications (29.03%), none requiring surgical intervention. According to Clavien grading, all complications were grade <2. The application of our ERP to our patients undergoing RC and VIP neobladder contributed to reduce postoperative morbidity. Copyright © 2013 S. Karger AG, Basel.

To evaluate the feasibility to perform peripartum hysterectomy (PH) with the introduction of LigaSure™ vessels-sealing device (LVSD) and how it influenced the surgical outcomes. We retrospectively evaluated procedures and outcome of women undergoing PH during the period between January 2001 and October 2013. Perioperative surgical results of patients undergoing PH using LVSD were compared to patients undergoing PH without LVSD. Forty-nine subjects had PH during the study period. Twenty (41%) hysterectomies were performed for placenta accreta, 8 (16%) for placenta previa, 21 (43%) for atony. Twenty-three subjects had PH using LVSD and 26 subjects had hysterectomy without the use of this device. We observe significant differences in estimated blood loss (p = 0.001), massive blood transfusions (>10 units RBC) (p = 0.025), operative time (p = 0.06). No difference in term of hospital stay and complications were observed (p = 0.78 and p = 0.35). One patient for each group had intraoperative complication (p = 0.9). The use of LVSD during PH does not increase operative complications, blood loss, and operative time in comparison to standard procedure.

Surgical limb lengthening is undertaken to correct pathological short stature. Among the possible complications related to this procedure, painful and retractile scars are a cause for both functional and cosmetic concern. Our team has already shown the efficacy of autologous fat grafting in the treatment of scars with varying aetiology, so we decided to apply this technique to scars related to surgical correction of dwarfism. A prospective study was conducted to evaluate the efficacy of autologous fat grafting in the treatment of post-surgical scars in patients with short-limb dwarfism using durometer measurements and a modified patient and observer scar assessment scale (POSAS), to which was added a parameter to evaluate movement impairment. Between January 2009 and September 2012, 36 children (28 female and 8 male) who presented retractile and painful post-surgical scars came to our unit and were treated with autologous fat grafting. Preoperative and postoperative mean durometer measurements were analysed using the analysis of variance (ANOVA) test and POSAS parameters were studied using the Wilcoxon rank sum test. There was a statistically significant reduction in all durometer measurements (p-value <0.05) and in all but one of the POSAS parameters (p-value <0.05) following treatment with autologous fat grafting. Surgical procedures to camouflage scars on lower limbs are not often used as a first approach and non-surgical treatments often lead to unsatisfactory results. In contrast, our autologous fat grafting technique in the treatment of post-surgical scars has been shown to be a valuable option in patients with short-limb dwarfism. There was a reduction of skin hardness and a clinical improvement of all POSAS parameters in all patients treated. Moreover, the newly introduced POSAS parameter appears to be reliable and we recommend that it is included to give a more complete evaluation of patient perception. Copyright © 2014 Elsevier Ltd.

A retrospective study. The aim of this study was to investigate the correlation between pelvic incidence (PI) and lumbar lordosis (LL) mismatch and knee flexion during standing in patients with lumbar degenerative diseases and to examine the effects of surgical correction of the PI-LL mismatch on knee flexion. Only several studies focused on knee flexion as a compensatory mechanism of the PI-LL mismatch. Little information is currently available on the effects of lumbar correction on knee flexion in patients with the PI-LL mismatch. A group of patients with lumbar degenerative diseases were divided into PI-LL match group (PI-LL ≤ 10°) and PI-LL mismatch group (PI-LL > 10°). A series of radiographic parameters and knee flexion angle (KFA) were compared between the two groups. The PI-LL mismatch group was further subdivided into operative and nonoperative group. The changes in KFA with PI-LL were examined. The PI-LL mismatch group exhibited significantly greater sagittal vertical axis (SVA), pelvic tilt (PT) and KFA, and smaller LL, thoracic kyphosis (TK), and sacral slope than the PI-LL match group. PI-LL, LL, PI, SVA, and PT were significantly correlated with KFA in the PI-LL mismatch group. From baseline to 6-month follow-up, all variables were significantly different in the operative group with the exception of PI, although there was no significant difference in any variable in the nonoperative group. The magnitude of surgical correction in the PI-LL mismatch was significantly correlated with the degree of spontaneous changes in KFA, PT, and TK. The PI-LL mismatch would contribute to compensatory knee flexion during standing in patients with lumbar degenerative disease. Surgical correction of the PI-LL mismatch could lead to a spontaneous improvement of compensatory knee flexion. The degree of improvement in knee flexion depends in part on the amount of correction in the PI-LL mismatch. 3.

We conducted this study to explore the influence of the ocular residual aberrations changes on contrast sensitivity(CS)function in eyes undergoing orthokeratology using adaptive optics technique.Nineteen subjects’ nineteen eyes were included in this study.The subjects were between 12 and 20years(14.27±2.23years)of age.An adaptive optics(AO)system was adopted to measure and compensate the residual aberrations through a 4-mm artificial pupil,and at the same time the contrast sensitivities were measured at five spatial frequencies(2,4,8,16,and 32 cycles per degree).The CS measurements with and without AO correction were completed.The sequence of the measurements with and without AO correction was randomly arranged without informing the observers.A two-interval forced-choice procedure was used for the CS measurements.The paired t-test was used to compare the contrast sensitivity with and without AO correction at each spatial frequency.The results revealed that the AO system decreased the mean total root mean square(RMS)from 0.356μm to 0.160μm(t=10.517,P<0.001),and the mean total higher-order RMS from 0.246μm to 0.095μm(t=10.113,P<0.001).The difference in log contrast sensitivity with and without AO correction was significant only at 8cpd(t=-2.51,P=0.02).Thereby we concluded that correcting the ocular residual aberrations using adaptive optics technique could improve the contrast sensitivity function at intermediate spatial frequency in patients undergoing orthokeratology.

Purpose To determine the ability of motion corrected optical coherence tomography (OCT) to measure the corneal refractive power change due to laser in situ keratomileusis (LASIK). Design Evaluation of a diagnostic test or technology in a cohort. Subjects 70 eyes from 37 subjects undergoing LASIK were measured preoperatively. 39 eyes from 22 subjects were measured postoperatively and completed the study. Methods Consecutive patients undergoing LASIK at the Duke Eye Center who consented to participate were imaged with Placido-ring topography, Scheimpflug photography and OCT on the day of their surgery. Patients were then reimaged with the same imaging systems at the post-operative month 3 visit. Change in pre- to post-operative corneal refractive power as measured by each of the imaging modalities was compared to the pre- to post-operative change in manifest refraction using t-test with generalized estimating equations. Main Outcome Measures Corneal refractive power change due to LASIK as measured by Placido-ring topography, Scheimpflug Photography, and OCT compared to the manifest refraction change vertexed to the corneal plane. The change in manifest refraction should correspond to the change in the corneal refractive power from LASIK and was considered the reference measurement. Results In 22 returning post-LASIK individuals (39 eyes), we found no significant difference between the clinically measured pre to post LASIK change in manifest refraction and both Scheimpflug photography (p = 0.714) and OCT (p = 0.216). In contrast, keratometry values from Placido-ring topography were found to be significantly different from the measured refractive change (p < 0.001). Additionally, of the three imaging modalities, OCT recorded the smallest mean absolute difference from the reference measurement with the least amount of variability. Conclusion Motion corrected OCT more accurately measures the change in corneal refractive power due to laser refractive surgery than currently available clinical devices. By offering accurate corneal refractive power measurements in normal and surgically modified subjects, OCT offers a compelling alternative to current clinical devices for determining corneal refractive power.

To study the safety, efficacy, and outcomes of manual cyclotorsion compensation in small incision lenticule extraction (SMILE) for myopic astigmatism. Eligible patients with myopia from -1.00 to -10.00 diopters (D) spherical equivalent with a minimum astigmatism of 0.75 D undergoing SMILE were included. Intraoperative cyclotorsion compensation was performed by gently rotating the cone and aligning the 0° to 180° limbal marks with the horizontal axis of the reticule of the right eye piece of the microscope of the femtosecond laser after activating the suction. In this study, 81 left eyes from 81 patients were analyzed for vector analysis of astigmatism. The mean cyclotorsion was 5.64° ± 2.55° (range: 2° to 12°). No significant differences were found for surgically induced astigmatism, difference vector, angle of error (AE), correction index, magnitude of error, index of success (IOS), and flattening index between 2 weeks and 3 months postoperatively (P > .05). The eyes were categorized into low (≤ 1.50 D, n = 37) and high (> 1.50 D, n = 44) cylinder groups. At 3 months, intergroup analysis showed a comparable correction index of 0.97 for the low and 0.93 for the high cylinder groups, suggesting a slight undercorrection of 3% and 7%, respectively (P = .14). However, the AE and IOS were significantly lower in the high compared to the low cylinder group (P = .032 and .024 for AE and IOS, respectively), suggesting better alignment of the treatment in the high cylinder group. However, the mean uncorrected distance visual acuity of both groups was comparable (P = .21), suggesting good visual outcomes in the low cylinder group despite a less favorable IOS. Manual compensation may be a safe, feasible, and effective approach to refine the results of astigmatism with SMILE, especially in higher degrees of cylinders. [J Refract Surg. 2017;33(8):506-512.].

Ambispective cohort review. To examine the effects of early mobilization on patient outcomes, complications profile, and 30-day readmission rates. Prolonged immobilization after surgery can result in functional decline and an increased risk of hospital-associated complications. We conducted an ambispective study of 125 elderly patients (>65 years) undergoing elective spinal surgery for correction of adult degenerative scoliosis. We identified all unplanned readmissions within 30 days of discharge. Unplanned readmissions were defined to have occurred as a result of either a surgical or a nonsurgical complication. "Days of immobility" was defined as the number of days until a patient moved out of bed beyond a chair. Patients in the top and bottom quartiles were dichotomized into "early ambulators" and "late ambulators", respectively. Early ambulators were ambulatory within 24 hours of surgery, whereas late ambulators were ambulatory at a minimum of 48 hours after surgery. Complication rates, duration of hospital stay, and 30-day readmission rates were compared between early ambulators and late ambulators. Baseline characteristics were similar between both cohorts. Compared with patients with a longer duration of immobility (i.e., late ambulators), the prevalence of at least one perioperative complication was significantly lower in the early ambulators cohort (30% vs. 54%, P = 0.06). The length of inhospital stay was 34% shorter in the early ambulators cohort (5.33 days vs. 8.11 days, P = 0.01). Functional independence was superior in the early ambulators cohort, with the majority of patients discharged directly home after surgery compared with late ambulators (71.2% vs. 22.0%, P = 0.01). Early ambulation after surgery significantly reduces the incidence of perioperative complications, shortens duration of inhospital stay, and contributes to improved perioperative functional status in elderly patients. Even a delay of 24 hours to ambulation is associated with higher complication rates and inferior functional outcomes. 3.

Correction of gynecomastia in males is a frequently performed aesthetic procedure. Various surgical options involving the removal of excess skin, fat, or glandular tissue have been described. However, poor aesthetic outcomes, including a flat or depressed pectoral area, limit the success of these techniques. The authors sought to determine patient satisfaction with the results of upper chest augmentation by direct intrapectoral fat injection in conjunction with surgical correction of gynecomastia. In this prospective study, 26 patients underwent liposuction and glandular excision, glandular excision alone, or Benelli-type skin excision. All patients received intramuscular fat injections in predetermined zones of the pectoralis major (PM). The mean volume of fat injected was 160 mL (range, 80-220 mL per breast) bilaterally. Patients were monitored for an average of 16 months (range, 8-24 months). Hematoma formation and consequent infraareolar depression was noted in 1 patient and was corrected by secondary lipografting. Mean patient satisfaction was rated as 8.4 on a scale of 1 (unsatisfactory) to 10 (highly satisfactory). Autologous intrapectoral fat injection performed simultaneously with gynecomastia correction can produce a masculine appearance. The long-term viability of fat cells injected into the PM needs to be determined. 4 Therapeutic. © 2015 The American Society for Aesthetic Plastic Surgery, Inc.

Several suspension methods are used to try to prevent pelvic organ prolapse (POP) after hysterectomy. We aimed to evaluate agreement on terminology and surgical procedure of these methods. We randomly chose 532 medical records of women with a history of hysterectomy from the Danish Hysterectomy and Hysteroscopy Database (DHHD). Additionally, we video-recorded 36 randomly chosen hysterectomies. The hysterectomies were registered in the DHHD. The material was categorized according to predefined suspension methods. Agreement compared suspension codes in DHHD (gynecologists' registrations) with medical records (gynecologists' descriptions) and with videos (reviewers' categorizations) respectively. Whether the vaginal vault was suspended (pooled suspension) or not (no suspension method + not described) was analyzed, in addition to each suspension method. Regarding medical records, agreement on terminology was good among patients undergoing pooled suspension in cases of hysterectomy via the abdominal and vaginal route (agreement 78.7, 92.3%). Regarding videos, agreement on surgical procedure was good among pooled suspension patients in cases of hysterectomy via the abdominal, laparoscopic, and vaginal routes (agreement 88.9, 97.8, 100%). Agreement on individual suspension methods differed regarding both medical records (agreement 0-90.1%) and videos (agreement 0-100%). Agreement on terminology and surgical procedure regarding suspension method was good in respect of pooled suspension. However, disagreement was observed when individual suspension methods and operative details were scrutinized. Better consensus of terminology and surgical procedure is warranted to enable further research aimed at preventing POP among women undergoing hysterectomy.

A review of surgical repair methods and patient outcomes for gluteal tendon tears.

Ebert, Jay R; Bucher, Thomas A; Ball, Simon V; Janes, Gregory C

2015-01-01

Advanced hip imaging and surgical findings have demonstrated that a common cause of greater trochanteric pain syndrome (GTPS) is gluteal tendon tears. Conservative measures are initially employed to treat GTPS and manage gluteal tears, though patients frequently undergo multiple courses of non-operative treatment with only temporary pain relief. Therefore, a number of surgical treatment options for recalcitrant GTPS associated with gluteal tears have been reported. These have included open trans-osseous or bone anchored suture techniques, endoscopic methods and the use of tendon augmentation for repair reinforcement. This review describes the anatomy, pathophysiology and clinical presentation of gluteal tendon tears. Surgical techniques and patient reported outcomes are presented. This review demonstrates that surgical repair can result in improved patient outcomes, irrespective of tear aetiology, and suggests that the patient with "trochanteric bursitis" should be carefully assessed as newer surgical techniques show promise for a condition that historically has been managed conservatively.

Traditionally, surgical intervention for patients with a spinal deformity has been considered for cosmetic benefits, but surgical intervention can alter the lung physiology or volumes and in turn leads to increase in physical capacity and exercise tolerance. Therefore, we conducted this to determine whether a surgical correction would restore the lung physiology, physical capacity and exercise tolerance in patients with kyphoscoliosis. To evaluate the usage of six-minute walk test scores and modified Borg scores as tools/measures for exercise tolerance in patients with spinal deformity and to study the effects of surgical correction of spinal deformity on exercise tolerance with above parameters as the measures. Thirty patients with spinal deformity, who had undergone surgery for deformity correction, were evaluated. All patients were investigated pre-operatively with x-rays of the spine (anteroposterior and lateral views). Clinical tests like breath holding time (after full inspiration) in number of seconds, modified Borg scores, six-minute walk test scores (heart rate, respiratory rate, maximum distance walked); were recorded as measures of exercise tolerance. The patients were followed up on the first, third, sixth and twelfth month post-operatively and tested clinically for breath holding time, modified Borg scores, six-minute walk test scores (heart rate, respiratory rate, maximum distance walked) and x-rays of the spine (anteroposterior and lateral views). In our study, breath holding time (p-value = 0.001) and modified Borg scores (p-value = 0.012) showed a significant improvement at 12 months post-operatively. We noted similar findings with heart rate, respiratory rate and maximum distance walked after a six-minute walk test. Improvements were noted in all the parameters, especially in the group of patients with greater than 60 degrees of cobb angle. However, the differences between the two groups (pre-operative cobb angle less than 60 degrees and pre-operative cobb angle more than 60 degrees) were not significant. The results were analysed and tested for significance using Student's t-test (paired and unpaired as appropriate) and Wilcoxon signed rank test. Surgical correction in cases of spinal deformity improves the cosmetic appearance and balance in the patients. Favourable results of surgical intervention were found in exercise tolerance with improvements in modified Borg scores, six-minute walk test results and breath holding time. The above parameters appear to be good tools for the assessment of physical capacity and exercise tolerance in patients with spinal deformity.

Importance Previous studies of checklist-based quality improvement interventions have reported mixed results. Objective To evaluate whether implementation of a checklist-based quality improvement intervention, Keystone Surgery, was associated with improved outcomes in patients undergoing general surgery in large statewide population. Design, Setting and Exposure Retrospective longitudinal study examining surgical outcomes in Michigan patients using Michigan Surgical Quality Collaborative clinical registry data from the years 2006–2010 (n=64,891 patients in 29 hospitals). Multivariable logistic regression and difference-in-differences analytic approaches were used to evaluate whether Keystone Surgery program implementation was associated with improved surgical outcomes following general surgery procedures, apart from existing temporal trends toward improved outcomes during the study period. Main Outcome Measures Risk-adjusted rates of superficial surgical site infection, wound complications, any complication, and 30-day mortality. Results Implementation of Keystone Surgery in participating centers (n=14 hospitals) was not associated with improvements in surgical outcomes during the study period. Adjusted rates of superficial surgical site infection (3.2 vs. 3.2%, p=0.91), wound complications (5.9 vs. 6.5%, p=0.30), any complication (12.4 vs. 13.2%, p=0.26), and 30-day mortality (2.1 vs. 1.9%, p=0.32) at participating hospitals were similar before and after implementation. Difference-in-differences analysis accounting for trends in non-participating centers (n=15 hospitals), and sensitivity analysis excluding patients receiving surgery in the first 6- or 12-months after program implementation yielded similar results. Conclusions and Relevance Implementation of a checklist-based quality improvement intervention did not impact rates of adverse surgical outcomes among patients undergoing general surgery in participating Michigan hospitals. Additional research is needed to understand why this program was not successful prior to further dissemination and implementation of this model to other populations. PMID:25588183

Cancellations have an important role in the effectiveness of the surgical schedule. Analyze the evolution of the cancellations during the years 1994-1997, after institution of several corrective measures. We started in 1994 together with the Quality Unit of the Hospital, a program to reduce surgical cancellations. It consisted in improvement of parents information, surgical schedule centralization, and increasing the awareness of the importance of constant improvement. Cancellations have been divided in: inevitables and inevitables, and analyzed for the entire Service and for each speciality. A significant reduction of cancellations have been obtain (from 12.38% in 1992 to 3.35% in 1997). The inevitable causes (no presentation, inadequate preparation and lack of time in the surgical room) have shown the most improvement. Although the inevitable causes (intercurrent disease) were also significantly improved, after obtaining prior information of the health of the child, by telephone call or parents advise. ENT is the speciality with greatest improvement by significant reduction of the non presentation and intercurrent disease. After corrective measures conjointly with a realistic surgical schedule, prior telephone call and improvement quality concept, have permitted a significant reduction of cancellations.

A grossly displaced segmental zygomatic arch fracture with marked ventro-lateral deviation of the left globe was diagnosed in a 3-month-old male German Shepherd dog following a bite injury. The fracture was approached via a modified lateral orbitotomy and a fragment of the lacrimal bone removed. The rostral portion of the fracture was stabilized with a 5-hole 2.0 dynamic compression plate bone plate. The surgical correction achieved sufficient skeletal fixation for proper anatomical reduction of the globe and excellent cosmetic and functional outcomes.

Orthognathic surgery has become an acceptable treatment plan for patients with various maxillofacial deformities. The rehabilitation of severe class III adult patients requires a complex interdisciplinary orthodontic and orthognathic approach. This presentation aims to show a case of combination of camouflage and bilateral sagittal split osteotomy (BSSO).Camouflage in maxillary arch was accepted after analysing visual treatment objective (VTO) and pleasing soft tissue compensation which gave us the clue to go ahead for surgical correction of excess mandibular length to achieve best aesthetic outcome while maintaining nature's compensation in upper arch.

Surgical correction of pectus excavatum (PE) via a minimally invasive approach involves placement of a steel bar, which is subsequently removed. The purpose of our study was to evaluate the incidence of pneumothorax and the role for chest radiography (CXR) in patients undergoing pectus bar removal. A retrospective review of 84 patients who underwent pectus bar removal from 2006 to 2014 was performed. Results of postoperative CXR, repeat imaging, need for chest thoracostomy tube placement, and complications were analyzed. Mean Haller index prior to correction was 4.3 ± 0.9. The mean time between PE repair and bar removal was 2.3 ± 0.6 years. Sixty-one patients (72.6 %) had a postoperative CXR. Thirty-one (50.8 %) had no acute findings, 20 (32.8 %) had findings of atelectasis or subcutaneous emphysema, and 10 (16.4 %) had a pneumothorax. One patient (1.6 %) had a second postoperative CXR for a small pneumothorax and rib fractures. There were two complications (2.4 %). No chest tubes were placed for pneumothorax, and 95 % of patients were discharged the day of surgery. Postoperative CXR following pectus bar removal is unnecessary given the low incidence of postoperative pneumothorax requiring intervention. Patients can be safely discharged the day of surgery without the need for routine postoperative chest imaging.

Prosthetic Correction of Postenucleation Socket Syndrome: A Case Report.

2014-12-01

Postenucleation socket syndrome is a frequent late complication of enucleation of eye globe. Several pathophysiological mechanisms have been proposed to account for the symptoms of postenucleation socket syndrome, which include lost orbital volume, superior sulcus deformity, upper eyelid ptosis, lower eyelid laxity, and backward tilt of the prosthesis. The goal of postenucleation socket syndrome treatment is to achieve the best possible functional and esthetic result. The treatment can be either conservative or surgical. For the patient interested in a non-surgical correction, the conservative treatment is simple and non invasive and can be done with prosthesis modification for good positioning, comfort, and mobility. This paper describes prosthetic correction of a patient with postenucleation socket syndrome by modified ocular prosthesis.

We provide a correction factor to be added in ablation algorithms when a Gaussian beam is used in photorefractive laser surgery. This factor, which quantifies the effect of pulse overlapping, depends on beam radius and spot size. We also deduce the expected post-surgical corneal radius and asphericity when considering this factor. Data on 141 eyes operated on LASIK (laser in situ keratomileusis) with a Gaussian profile show that the discrepancy between experimental and expected data on corneal power is significantly lower when using the correction factor. For an effective improvement of post-surgical visual quality, this factor should be applied in ablation algorithms that do not consider the effects of pulse overlapping with a Gaussian beam.

This article aimed to present a case of 22 year-old Thai female with cleft lip and palate who had malocclusion developed from dental problems, skeletal disharmony and unrepaired alveolar cleft. The treatment was orthodontic combined with one-stage surgical correction which corrected skeletal discrepancy and alveolar cleft in single operation. After treatment, the patient had improved in facial esthetics, attaining good occlusal function and continuous maxillary dental arch. This procedure can reduce morbidity, preclude a second hospitalization and the cost of two-stage surgical correction. However this is only an alternative treatment for adult cleft patients who need late alveolar bone graft and orthognathic surgery.

To describe the surgical technique of complex distal femoral deformity correction with the aid of stereolithography apparatus (SLA) biomodels, stabilized with locking plate fixation. Full-size replica epoxy bone biomodels of the affected femurs (4 dogs/ 5 limbs) were used as templates for surgical planning. A rehearsal procedure was performed on the biomodels aided by a guide wire technique and stabilized with locking plate fixation. Surgery performed in all dogs was guided by the rehearsal procedure. All pre-contoured implants were subsequently used in the definitive surgical procedure with minimal modification. All dogs had markedly improved, with near normal functional outcomes; all but one had a mild persistent lameness at the final in-hospital follow-up examination (mean: 54.4 weeks; range: 24-113 weeks after surgery). All femurs healed without complications (mean: 34 weeks, median: 12 weeks; range: 8-12 weeks for closing osteotomies, and 26-113 weeks for opening wedge osteotomies). Long-term follow-up examination (mean: 28.6 months; range: 5-42 months) revealed all but one owner to be highly satisfied with the outcome. Complications were observed in two dogs: prolonged tibiotarsal joint decreased flexion that resolved with physical therapy. In one of these dogs, iatrogenic transection of the long digital extensor tendon was repaired, and the other had a peroneal nerve neurapraxia. Stereolithography apparatus biomodels and rehearsal surgery simplified the definitive surgical corrections of complex femoral malunions and resulted in good functional outcomes.

Retrospective study. To analyze the perioperative major non-neurological complications (MNNCs) in posterior vertebral column resection (PVCR) procedures for severe rigid deformities and to identify the factors that may increase the risk. Although surgeons constantly attempted to increase the corrective efficacy and neurological safety after PVCR, there are still significant risks of major and potentially life-threatening complications. A total of 105 consecutive patients with severe rigid deformity who underwent 1-stage PVCR at a single center from 2004 to 2013 were reviewed. The demographic data, medical and surgical histories, perioperative and final follow-up radiographical measurements, and prevalence of perioperative MNNCs were reviewed. The mean age of patients at the time of surgery was 18.9 years (range: 10-45 yr). The major curve of scoliosis was 108.9 ± 25.5 preoperatively and 37.2 ± 16.8 at the final follow-up, and segmental kyphosis was from 89.8 ± 31.1 to 30.4 ± 15.3. There were 31 MNNCs in 24 patients: 16 respiratory complications in 13 patients, 9 cardiovascular adverse events in 7 cases, 1 malignant hyperthermia, and 1 optic deficit. There were 3 patients with wound infection, and 1 of them had to undergo partial removal of the implant for infection control. One patient with neurofibromatosis died 1 day after operation. Factors that showed no relationships with an increased prevalence of MNNCs were age, sex, presence of cardiac disease or neural axis malformation, and both sagittal and coronal correction rate. Patients with T6 and upper resected level, undergoing PVCR at the early period, showed a trend toward more MNNCs encountered. Moreover, nonidiopathic deformity, large scoliotic curve greater than 150°, percent predicated forced vital capacity and forced expiratory volume in 1 second (FEV1.0) less than 40%, and estimated blood loss volume more than 5000 mL were identified as risk factors associated with MNNCs. Patients who had undergone PVCR experienced expected higher rate of MNNCs, with an overall prevalence of 22.9%. When considering PVCR, it is important to recognize the significantly higher inherent risks and provide appropriate preoperative counseling on the risks and benefits of surgery. 3.

Studies have shown that physiopathological changes to the respiratory system can occur following thoracic and abdominal surgery. Laminectomy is considered to be a peripheral surgical procedure, but it is possible that thoracic spinal surgery exerts a greater influence on lung function. The aim of this study was to evaluate the pulmonary volumes and maximum respiratory pressures of patients undergoing cervical, thoracic or lumbar spinal surgery. Prospective study in a tertiary-level university hospital. Sixty-three patients undergoing laminectomy due to diagnoses of tumors or herniated discs were evaluated. Vital capacity, tidal volume, minute ventilation and maximum respiratory pressures were evaluated preoperatively and on the first and second postoperative days. Possible associations between the respiratory variables and the duration of the operation, surgical diagnosis and smoking status were investigated. Vital capacity and maximum inspiratory pressure presented reductions on the first postoperative day (20.9% and 91.6%, respectively) for thoracic surgery (P = 0.01), and maximum expiratory pressure showed reductions on the first postoperative day in cervical surgery patients (15.3%; P = 0.004). The incidence of pulmonary complications was 3.6%. There were reductions in vital capacity and maximum respiratory pressures during the postoperative period in patients undergoing laminectomy. Surgery in the thoracic region was associated with greater reductions in vital capacity and maximum inspiratory pressure, compared with cervical and lumbar surgery. Thus, surgical manipulation of the thoracic region appears to have more influence on pulmonary function and respiratory muscle action.

Hip dysplasia, pelvic obliquity, and scoliosis in cerebral palsy: a qualitative analysis using 3D CT reconstruction

1998-06-01

Five patients with cerebral palsy, hip dysplasia, pelvic obliquity, and scoliosis were evaluated retrospectively using three dimensional computed tomography (3DCT) scans of the proximal femur, pelvis, and lumbar spine to qualitatively evaluate their individual deformities by measuring a number of anatomical landmarks. Three dimensional reconstructions of the data were visualized, analyzed, and then manipulated interactively to perform simulated osteotomies of the proximal femur and pelvis to achieve surgical correction of the hip dysplasia. Severe deformity can occur in spastic cerebral palsy, with serious consequences for the quality of life of the affected individuals and their families. Controversy exists regarding the type, timing and efficacy of surgical intervention for correction of hip dysplasia in this population. Other authors have suggested 3DCT studies are required to accurately analyze acetabular deficiency, and that this data allows for more accurate planning of reconstructive surgery. It is suggested here that interactive manipulation of the data to simulate the proposed surgery is a clinically useful extension of the analysis process and should also be considered as an essential part of the pre-operative planning to assure that the appropriate procedure is chosen. The surgical simulation may reduce operative time and improve surgical correction of the deformity.

Evaluation of new Deflux administration techniques: intraureteric HIT and Double HIT for the endoscopic correction of vesicoureteral reflux.

Kirsch, Andrew J; Arlen, Angela M

2014-09-01

Vesicoureteral reflux (VUR) is one of the most common urologic diagnoses affecting children, and optimal treatment requires an individualized approach that considers potential risks. Management options include observation with or without continuous antibiotic prophylaxis and surgical correction via endoscopic, open or laparoscopic/robotic approaches. Endoscopic correction of VUR is an outpatient procedure associated with decreased morbidity compared with ureteral reimplantation. The concept of ureteral hydrodistention and intraluminal submucosal injection (Hydrodistention Implantation Technique [HIT]) has led to improved success rates in eliminating VUR compared with the subureteral transurethral injection technique. Further modifications now include use of proximal and distal intraluminal injections (Double HIT) that result in coaptation of both the ureteral tunnel and orifice. Endoscopic injection of dextranomer/hyaluronic acid copolymer, via the HIT and Double HIT, has emerged as a highly successful, minimally invasive alternative to open surgical correction, with minimal associated morbidity.

We describe a new video-assisted operative technique for correction of pectus carinatum (PC) using a modified Nuss procedure. A new design of the steel bar was developed, so that it could be introduced and placed in a suitable position through very small skin incisions. Substantial modifications were introduced in the bar length and shape aimed at facilitating insertion and subsequent removal when required. All the surgical manoeuvres took place under direct vision using a 30° thoracoscope. Single unilateral fixation of the bar in a subpectoral pocket provided satisfactory stabilisation without the need for lateral stabilisers. Adequate correction of the deformity was achieved with minor postoperative scars. Our results support the view that minimally invasive surgical repair should be preferred over open surgery for correction of pectus carinatum in young adults and children.

Scoliosis is defined as a spinal pathology characterized as a three-dimensional deformity of the spine combined with vertebral rotation. Treatment for severe scoliosis is achieved when the scoliotic spine is surgically corrected and fixed using implanted rods and screws. Several studies performed biomechanical modeling and corrective forces measurements of scoliosis correction. These studies were able to predict the clinical outcome and measured the corrective forces acting on screws, however, they were not able to measure the intraoperative three-dimensional geometry of the spinal rod. In effect, the results of biomechanical modeling might not be so realistic and the corrective forces during the surgical correction procedure were intra-operatively difficult to measure. Projective geometry has been shown to be successful in the reconstruction of a three-dimensional structure using a series of images obtained from different views. In this study, we propose a new method to measure the three-dimensional geometry of an implant rod using two cameras. The reconstruction method requires only a few parameters, the included angle θ between the two cameras, the actual length of the rod in mm, and the location of points for curve fitting. The implant rod utilized in spine surgery was used to evaluate the accuracy of the current method. The three-dimensional geometry of the rod was measured from the image obtained by a scanner and compared to the proposed method using two cameras. The mean error in the reconstruction measurements ranged from 0.32 to 0.45 mm. The method presented here demonstrated the possibility of intra-operatively measuring the three-dimensional geometry of spinal rod. The proposed method could be used in surgical procedures to better understand the biomechanics of scoliosis correction through real-time measurement of three-dimensional implant rod geometry in vivo.

Purpose Facial asymmetry often persists even after mandibular deviation corrected by the bilateral sagittal split ramus osteotomy (BSSRO) operation, since the reference facial sagittal plane for the asymmetry analysis is usually set up before the mandibular menton (Me) point correction. Our aim is to develop a predictive and quantitative method to assess the true asymmetry of the mandible after a midline correction performed by a virtual BSSRO, and to verify its availability by evaluation of the post-surgical improvement. Patients and Methods A retrospective cohort study was conducted at the Hospital of Stomatology, Sun Yat-sen University (China) of patients with pure hemi-mandibular elongation (HE) from September 2010 through May 2014. Mandibular models were reconstructed from CBCT images of patients with pre-surgical orthodontic treatment. After mandibular de-rotation and midline alignment with virtual BSSRO, the elongation hemi-mandible was virtually mirrored along the facial sagittal plane. The residual asymmetry, defined as the superimposition and boolean operation of the mirrored elongation side on the normal side, was calculated, including the volumetric differences and the length of transversal and vertical asymmetry discrepancy. For more specific evaluation, both sides of the hemi-mandible were divided into the symphysis and parasymphysis (SP), mandibular body (MB), and mandibular angle (MA) regions. Other clinical variables include deviation of Me point, dental midline and molar relationship. The measurement of volumetric discrepancy between the two sides of post-surgical hemi-mandible were also calculated to verify the availability of virtual surgery. Paired t-tests were computed and the P value was set at .05. Results This study included 45 patients. The volume differences were 407.8±64.8 mm3, 2139.1±72.5 mm3, and 422.5±36.9 mm3; residual average transversal discrepancy, 1.9 mm, 1.0 mm, and 2.2 mm; average vertical discrepancy, 1.1 mm, 2.2 mm, and 2.2 mm (before virtual surgery). The post-surgical volumetric measurement showed no statistical differences between bilateral mandibular regions. Conclusions Mandibular asymmetry persists after Me point correction. A 3D quantification of mandibular residual asymmetry after Me point correction and mandible de-rotation with virtual BSSRO sets up a true reference mirror plane for comprehensive asymmetry assessment of bilateral mandibular structure, thereby providing an accurate guidance for orthognathic surgical planning.

The National Surgical Quality Improvement Program (NSQIP) of the American College of Surgeons provides risk-adjusted surgical outcome measures for participating hospitals that can be used for performance improvement of surgical mortality and morbidity. A surgical clinical nurse reviewer collects 135 clinical variables including preoperative risk factors, intraoperative variables, and 30-day postoperative mortality and morbidity outcomes for patients undergoing major surgical procedures. A report on mortality and complications is prepared twice a year. This article summarizes briefly the history of NSQIP and how its report on surgical outcomes can be used for performance improvement within a hospital system. In particular, it describes how to drive performance improvement with NSQIP data using the example of postoperative respiratory complications--a major factor of postoperative mortality. In addition, this article explains the benefit of a collaborative of several participating NSQIP hospitals and describes how to develop a "playbook" on the basis of an outcome improvement project.

The difference between medial (MAOR) and anterior (AAOR) approaches for open reduction of developmental hip dysplasia in terms of risk for avascular necrosis (AVN) and need for further corrective surgery (FCS, femoral and/or acetabular osteotomy) is unclear. This study compared age-matched cohorts undergoing either MAOR or AAOR in terms of these 2 primary outcomes. Prognostic impact of presence of ossific nucleus at time of open reduction was also investigated. Institutional review board approval was obtained. Nineteen hips (14 patients) managed by MAOR were matched with 19 hips (18 patients) managed by AAOR based on age at operation (mean 6.0; range, 1.4 to 14.9 mo). Patients with neuromuscular conditions and known connective tissue disorders were excluded. Primary outcomes assessed at minimum 2 years' follow-up included radiographic evidence of AVN (Kalamchi and MacEwen) or requiring FCS. MAOR and AAOR cohorts were similar regarding age at open reduction, sex, laterality, and follow-up duration. One hip in each group had AVN before open reduction thus were excluded from AVN analysis. At minimum 2 years postoperatively (mean 6.2; range, 1.8 to 11.7 y), 4/18 (22%) MAOR and 5/18 (28%) AAOR met the same criteria for AVN (P=1.0). No predictors of AVN could be identified by regression analysis. Presence of an ossific nucleus preoperatively was not a protective factor from AVN (P=0.27). FCS was required in 4/19 (21%) MAOR and 7/19 (37%) AAOR hips (P=0.48). However, 7/12 (54%) hips failing closed reduction required FCS compared with 4/26 (16%) hips without prior failed closed reduction (P=0.024). Cox regression analysis showed that patients who failed closed reduction had an annual risk of requiring FCS approximately 6 times that of patients without a history of failed closed reduction (hazard ratio=6.1; 95% CI, 1.5-24.4; P=0.009), independent of surgical approach (P=0.55) or length of follow-up (P=0.78). In this study of age-matched patients undergoing either MAOR or AAOR, we found no association between surgical approach and risk of AVN or FCS. In addition, we identified no protective benefit of a preoperative ossific nucleus in terms of development of AVN. However, failing closed reduction was associated with a 6-fold increased annual risk of requiring FCS. To the best of our knowledge, this is the first study comparing these 2 surgical techniques in an age-matched manner. It further corroborates previous studies stating that there may be no difference in risk of AVN based on surgical approach or presence of ossific nucleus preoperatively.

Adolescent idiopathic scoliosis is a complex spinal pathology characterized as a three-dimensional spine deformity combined with vertebral rotation. Various surgical techniques for correction of severe scoliotic deformity have evolved and became more advanced in applying the corrective forces. The objective of this study was to investigate the relationship between corrective forces acting on deformed rods and degree of scoliosis correction. Implant rod geometries of six adolescent idiopathic scoliosis patients were measured before and after surgery. An elasto-plastic finite element model of the implant rod before surgery was reconstructed for each patient. An inverse method based on Finite Element Analysis was used to apply forces to the implant rod model such that it was deformed the same after surgery. Relationship between the magnitude of corrective forces and degree of correction expressed as change of Cobb angle was evaluated. The effects of screw configuration on the corrective forces were also investigated. Corrective forces acting on rods and degree of correction were not correlated. Increase in number of implant screws tended to decrease the magnitude of corrective forces but did not provide higher degree of correction. Although greater correction was achieved with higher screw density, the forces increased at some level. The biomechanics of scoliosis correction is not only dependent to the corrective forces acting on implant rods but also associated with various parameters such as screw placement configuration and spine stiffness. Considering the magnitude of forces, increasing screw density is not guaranteed as the safest surgical strategy. Copyright © 2012 Elsevier Ltd. All rights reserved.

Technical progress in the surgical operating room (OR) increases constantly, facilitating the development of intelligent OR systems functioning as "safety backup" in the background of surgery. Precondition is comprehensive data retrieval to identify imminent risky situations and inaugurate adequate security mechanisms. Radio-frequency-identification (RFID) technology may have the potential to meet these demands. We set up a pilot study investigating feasibility and appliance reliability of a stationary RFID system for real-time surgical sponge monitoring (passive tagged sponges, position monitoring: mayo-stand/abdominal situs/waste bucket) and OR team tracking (active transponders, position monitoring: right/left side of OR table). In vitro: 20/20 sponges (100%) were detected on the mayo-stand and within the OR-phantom, however, real-time detection accuracy declined to 7/20 (33%) when the tags were moved simultaneously. All retained sponges were detected correctly. In vivo (animal): 7-10/10 sterilized sponges (70%-100%) were detected correctly within the abdominal cavity. OR-team: detection accuracy within the OR (surveillance antenna) and on both sides of the OR table (sector antenna) was 100%. Mean detection time for position change (left to right side and contrariwise) was 30-60 s. No transponder failure was noted. This is the first combined RFID system that has been developed for stationary use in the surgical OR. Preclinical evaluation revealed a reliable sponge tracking and correct detection of retained textiles (passive RFID) but also demonstrated feasibility of comprehensive data acquisition of team motion (active RFID). However, detection accuracy needs to be further improved before implementation into the surgical OR. Copyright © 2012 Elsevier Inc. All rights reserved.

Iatrogenic flattening of lumbar lordosis in patients with adolescent idiopathic scoliosis (AIS) was a major downside of first generation instrumentation. Current instrumentation systems allow a three-dimensional scoliosis correction, but flattening of lumbar lordosis remains a significant problem which is associated with decreased health-related quality of life. This study sought to identify risk factors for loss of lumbar lordosis in patients who had surgical correction of AIS with the use of segmental instrumentation. Patients were included if they had surgical correction for AIS with segmental pedicle screw instrumentation Lenke type 1 or 2 and if they had a minimum follow-up of 24 months. Two groups were created, based on the average loss of lumbar lordosis. The two groups were then compared and multivariate analysis was performed to identify parameters that correlated to loss of lumbar lordosis. Four hundred and seventeen patients were analyzed for this study. The average loss of lumbar lordosis at 24 months follow-up was an increase of 10° lordosis for group 1 and a decrease of 15° for group 2. Risk factors for loss of lumbar lordosis included a high preoperative lumbar lordosis, surgical decrease of thoracic kyphosis, and the particular operating surgeon. The lowest instrumented vertebra or spinopelvic parameters were two of many parameters that did not seem to influence loss of lumbar lordosis. This study identified important risk factors for decrease of lumbar lordosis in patients who had surgical treatment for AIS with segmental pedicle screw instrumentation, including a high preoperative lumbar lordosis, surgical decrease of thoracic kyphosis, and factors attributable to a particular operating surgeon that were not quantified in this study.

Neoplastic disease is common in pet birds, particularly in psittacines, and treatment should be primarily aimed at tumor eradication. Nineteen cases of pet birds submitted to diagnostic and/or therapeutic surgical procedures due to neoplastic disease characterized by the presence of visible masses were retrospectively analyzed; affected species, types of neoplasms and respective locations, and outcomes of surgical procedures were determined. All birds undergoing surgery belonged to the order Psittaciformes; the Blue-fronted parrot (Amazona aestiva) was the prevalent species. Lipoma was the most frequent neoplasm in the sample studied. Most neoplasms affected the integumentary system, particularly the pericloacal area. Tumor resection was the most common surgical procedure performed, with high resolution and low recurrence rates.

There is scarce evidence about the prognosis of venous thromboembolism in patients undergoing orthopedic surgery and in patients suffering non-surgical trauma. We used the RIETE database (Registro Informatizado de pacientes con Enfermedad Trombo Embólica) to compare the prognosis of venous thromboembolism and the use of thromboprophylaxis in patients undergoing different orthopedic procedures and in trauma patients not requiring surgery. From March 2001 to March 2015, a total of 61,789 patients were enrolled in RIETE database. Of these, 943 (1.52%) developed venous thromboembolism after elective arthroplasty, 445 (0.72%) after hip fracture, 1,045 (1.69%) after non-major orthopedic surgery and 2,136 (3.46%) after non-surgical trauma. Overall, 2,283 patients (50%) initially presented with pulmonary embolism. Within the first 90 days of therapy, 30 patients (0.66%; 95% CI 0.45-0.93) died from pulmonary embolism. The rate of fatal pulmonary embolism was significantly higher after hip fracture surgery (n = 9 [2.02%]) than after elective arthroplasty (n = 5 [0.53%]), non-major orthopedic surgery (n = 5 [0.48%]) or non surgical trauma (n = 11 [0.48%]). Thromboprophylaxis was more commonly used for hip fracture (93%) or elective arthroplasty (94%) than for non-major orthopedic surgery (71%) or non-surgical trauma (32%). Major bleeding was significantly higher after hip fracture surgery (4%) than that observed after elective arthroplasty (1.6%), non-major orthopedic surgery (1.5%) or non-surgical trauma (1.4%). Thromboprophylaxis was less frequently used in lower risk procedures despite the absolute number of fatal pulmonary embolism after non-major orthopedic surgery or non-surgical trauma, exceeded that observed after high risk procedures.

Aneurysms and dissections of the right-sided aortic arch are rare and published data are limited to a few case reports and small series. The optimal treatment strategy of this entity and the challenges associated with their management are not yet fully investigated and conclusive. We performed a systematic review of the literature to identify all patients who underwent surgical or endovascular intervention for right aortic arch aneurysms or dissections. The search was limited to the articles published only in English. We focused on presentation and critically assessed different management strategies and outcomes. We identified 74 studies that reported 99 patients undergoing surgical or endovascular intervention for a right aortic arch aneurysm or dissection. The median age was 61 years. The commonest presenting symptoms were chest or back pain and dysphagia. Eighty-eight patients had an aberrant left subclavian artery with only 11 patients having the mirror image variant of a right aortic arch. The commonest pathology was aneurysm arising from a Kommerell's diverticulum occurring in over 50% of the patients. Twenty-eight patients had dissections, 19 of these were Type B and 9 were Type A. Eighty-one patients had elective operations while 18 had emergency procedures. Sixty-seven patients underwent surgical treatment, 20 patients had hybrid surgical and endovascular procedures and 12 had totally endovascular procedure. There were 5 deaths, 4 of which were in patients undergoing emergency surgery and none in the endovascular repair group. Aneurysms and dissections of a right-sided aortic arch are rare. Advances in endovascular treatment and hybrid surgical and endovascular management are making this rare pathology amenable to these approaches and may confer improved outcomes compared with conventional extensive repair techniques.

Total joint arthroplasty (TJA) is a highly successful treatment, but is burdensome to the national healthcare budget. National quality initiatives seek to reduce costly complications. Smoking's role in perioperative complication after TJA is less well known. This study aims to identify smoking's independent contribution to the risk of short-term complication after TJA. All patients undergoing primary TJA between 2011 and 2012 were selected from the American College of Surgeon's National Surgical Quality Improvement Program's database. Outcomes of interest included rates of readmission, reoperation, mortality, surgical complications, and medical complications. To eliminate confounders between smokers and nonsmokers, a propensity score was used to generate a 1:1 match between groups. A total of 1251 smokers undergoing TJA met inclusion criteria. Smokers in the combined total hip and knee arthroplasty cohort had higher 30-day readmission (4.8% vs 3.2%, P = .041), were more likely to have a surgical complication (odds ratio 1.84, 95% confidence interval 1.21-2.80), and had a higher rate of deep surgical site infection (SSI) (1.1% vs 0.2%, P = .007). Analysis of total hip arthroplasty only revealed that smokers had higher rates of deep SSI (1.3% vs 0.2%, P = .038) and higher readmission rate (4.3% vs 2.2%, P = .034). Analysis of total knee arthroplasty only revealed greater surgical complications (2.8% vs 1.2%, P = .048) and superficial SSI (1.8% vs 0.2%, P = .002) in smokers. Smoking in TJA is associated with higher rates of SSI, surgical complications, and readmission. Copyright © 2017 Elsevier Inc. All rights reserved.

The degree of neuromuscular blockade is one of the important factors that determine the condition of surgical space during laparoscopic surgery. Magnesium sulfate potentiates the actions of neuromuscular blocking agent, and we hypothesized that intraoperative magnesium sulfate infusion may improve surgical space condition during laparoscopic surgery. Eighty-four patients undergoing elective laparoscopic gastrectomy were randomized to receive isotonic saline (group C) or magnesium sulfate (group M, loading dose with 50 mg/kg over 10 min and then 15 mg/kg/h by continuous infusion) to maintain the moderate neuromuscular blockade using rocuronium. Two experienced surgeons scored the quality of surgical space condition using a 5-point surgical rating scale (SRS). The secondary outcomes included recovery profiles, postoperative pain and adverse events. The SRS in group M was higher than that of group C. The proportion of patients with a SRS of 5 (optimal) was 2.7 % in the group C and 40.5 % in the group M (P < 0.0001) although a lower amount of rocuronium was required in group M than group C [24.2 (6.5) mg/h for group M vs. 27.5 (6) mg/h for group C; P = 0.017]. Pain after operation site was less severe in group M than in group C at postoperative 24 h (P = 0.009). Recovery profiles and adverse events were similar between the two groups. Intraoperative administration of magnesium sulfate improved the quality of surgical space conditions and decreased neuromuscular blocking agent requirement and postoperative pain in patients undergoing laparoscopic gastrectomy.

Little is known about the perioperative complication rates of the surgical management of midshaft clavicle nonunions. The purpose of the current study was to report on the perioperative complication rates after surgical management of nonunions and to compare them with complication rates of acute fractures using a population cohort. The American College of Surgeons National Surgical Quality Improvement Program database was queried to identify patients who had undergone open reduction-internal fixation of midshaft clavicle fractures between 2007 and 2013. Patients were stratified by operative indication: acute fracture or nonunion. Patient characteristics and 30-day complication rates were compared between the 2 groups using univariate and multivariate analyses. A total of 1215 patients were included in our analysis. Of these, 1006 (82.8%) were acute midshaft clavicle fractures and 209 (17.2%) were midshaft nonunions. Patients undergoing surgical fixation for nonunion had a higher rate of total complications compared with the acute fracture group (5.26% vs. 2.28%; P = .034). On multivariate analysis, patients with a nonunion were at a >2-fold increased risk of any postsurgical complication (odds ratio, 2.29 [95% confidence interval, 1.05-5.00]; P = .037) and >3-fold increased risk of a wound complication (odds ratio, 3.22 [95% confidence interval, 1.02-10.20]; P = .046) compared with acute fractures. On the basis of these findings, patients undergoing surgical fixation for a midshaft clavicle nonunion are at an increased risk of short-term complications compared with acute fractures. This study provides additional information to consider in making management decisions for these common injuries. Copyright © 2016 Journal of Shoulder and Elbow Surgery Board of Trustees.

With the adoption of routine screening mammography, breast cancers are being diagnosed at earlier stages, with DCIS now accouting for 22.5% of all newly diagnosed breast cancers. This has been attributed to both increased breast cancer awareness and improvements in breast imaging techniques. How have these changes, including the increased use of image-guided sampling techniques, influenced the clinical practice of breast surgery? The institutional pathology database was queried for all breast surgeries, including breast reconstruction, performed in 1995 and 2005. Cosmetic procedures were excluded. The results were analysed utilizing the Chi-square test. Surgical indications changed during 10-year study period, with an increase in preoperatively diagnosed cancers undergoing definitive surgical management. ADH, and to a lesser extent, ALH, became indications for surgical excision. Fewer surgical biopsies were performed for indeterminate abnormalities on breast imaging, due to the introduction of stereotactic large core biopsy. While the rate of benign breast biopsies remained constant, there was a higher percentage of precancerous and DCIS cases in 2005. The overall rate of mastectomy decreased from 36.8% in 1995 to 14.5% in 2005. With the increase in sentinel node procedures, the rate of ALND dropped from 18.3% to 13.7%. Accompanying the increased recognition of early-stage cancers, the rate of positive ALND also decreased, from 43.3% to 25.0%. While the rate of benign breast biopsies has remained constant over a recent 10-year period, fewer diagnostic surgical image-guided biopsies were performed in 2005. A greater percentage of patients with breast cancer or preinvasive disease have these diagnoses determined before surgery. More preinvasive and Stage 0 cancers are undergoing surgical management. Earlier stage invasive cancers are being detected, reflected by the lower incidence of axillary nodal metastases.

Surgical results can be assessed as a function of what was aimed for, what was done, and what was achieved. One of the aims of refractive surgery is to reduce astigmatism; the smaller the postoperative astigmatism the better the result. Determination of what was done--that is, the surgical effect, can be calculated from the preoperative and postoperative astigmatism. A simplified formulation is described which facilitates the calculation (magnitude and direction) of this surgical effect. In addition, an expression for surgical accuracy is described, as a function of what was aimed for and what was achieved.

Long-Term-Monitoring (LTM) is a valuable tool for seizure localization/lateralization among children with refractory-epilepsy undergoing pre-surgical-monitoring. The aim of this study was to examine the factors predicting occurrence of single/multiple seizures in children undergoing pre-surgical monitoring in the LTM unit. Chart review was done on 95 consecutive admissions on 92 children (40 females) admitted to the LTM-unit for pre-surgical workup. Relationship between occurrence of multiple (≥ 3) seizures and factors such as home seizure-frequency, demographics, MRI-lesions/seizure-type and localization/AED usage/neurological-exam/epilepsy-duration was evaluated by logistic-regression and survival-analysis. Home seizure-frequency was further categorized into low (up-to 1/month), medium (up-to 1/week) and high (>1/week) and relationship of these categories to the occurrence of multiple seizures was evaluated. Mean length of stay was 5.24 days in all 3 groups. Home seizure frequency was the only factor predicting the occurrence of single/multiple seizures in children undergoing presurgical workup. Other factors (age/sex/MRI-lesions/seizure-type and localization/AED-usage/neurological-exam/epilepsy-duration) did not affect occurrence of single/multiple seizures or time-to-occurrence of first/second seizure. Analysis of the home-seizure frequency categories revealed that 98% admissions in high-frequency, 94% in the medium, and 77% in low-frequency group had at-least 1 seizure recorded during the monitoring. Odds of first-seizure increased in high vs. low-frequency group (p=0.01). Eighty-nine percent admissions in high-frequency, 78% in medium frequency, versus 50% in low-frequency group had ≥ 3 seizures. The odds of having ≥ 3 seizures increased in high-frequency (p=0.0005) and in medium-frequency (p=0.007), compared to low-frequency group. Mean time-to-first-seizure was 2.7 days in low-frequency, 2.1 days in medium, and 2 days in high-frequency group. Time-to-first-seizure in high and medium-frequency was less than in low-frequency group (p<0.0014 and p=0.038). Majority of the admissions (92%) admitted to the LTM-unit for pre-surgical workup had at-least one seizure during a mean length of stay of 5.24 days. Home seizure-frequency was the only predictor influencing occurrence of single/multiple seizures in the LTM unit. Patients with low seizure-frequency are at risk for completing the monitoring with less than the optimum number (<3) of seizures captured. Copyright © 2013 British Epilepsy Association.

Paediatric obstructive sleep apnoea: is our operative management evidence-based?

Pabla, L; Duffin, J; Flood, L; Blackmore, K

2018-04-01

Despite the plethora of publications on the subject of paediatric obstructive sleep apnoea, there seems to be wide variability in the literature and in practice, regarding recourse to surgery, the operation chosen, the benefits gained and post-operative management. This may reflect a lack of high-level evidence. A systematic review of four significant controversies in paediatric ENT was conducted from the available literature: tonsillectomy versus tonsillotomy, focusing on the evidence base for each; anaesthetic considerations in paediatric obstructive sleep apnoea surgery; the objective evidence for the benefits of surgical treatment for obstructive sleep apnoea; and the medical treatment options for residual obstructive sleep apnoea after surgical treatment. There are many gaps in the evidence base for the surgical correction of obstructive sleep apnoea. There is emerging evidence favouring subtotal tonsillectomy. There is continuing uncertainty around the prediction of the level of post-operative care that any individual child might require. The long-term benefit of surgical correction is a particularly fertile ground for further research.

In the last few years there have been increasing claims that robotic assisted laparoscopic radical prostatectomy decreases short-term morbidity in patients undergoing surgical treatment for prostate cancer. However, there is surprisingly little objective evidence to support this point, which is often used to market the procedure to patients. To address this issue we prospectively evaluated patients undergoing open and robotic assisted laparoscopic radical prostatectomy at baseline and weekly through the postoperative period using a validated questionnaire. A total of 162 men undergoing radical prostatectomy, including open radical prostatectomy in 120 and robotic assisted laparoscopic radical prostatectomy in 42, for clinically localized prostate cancer completed the SF-12, version 2 Physical and Mental Health Survey Acute Form preoperatively and each week postoperatively for 6 weeks. Physical and Mental Component Scores were calculated from the questionnaires at each time point. Comparisons between the 2 surgical approaches were made at each time point. No significant differences were seen between the open and robotic assisted laparoscopic radical prostatectomy groups with regard to patient age, clinical stage or preoperative prostate specific antigen. Mean surgical blood loss was significantly higher in the open group compared to that in the robotic assisted laparoscopic group. Physical Component Scores in the robotic assisted laparoscopic group were significantly higher than those in the open cohort beginning postoperative week 1 and extending through week 6. On statistical extrapolation Physical Component Scores returned to baseline between weeks 5 and 6 postoperatively in the robotic assisted laparoscopic group and between weeks 6 and 7 in the open group. Mental Component Score scores were not statistically different between the groups except preoperatively. This study helps prospectively define short-term health related quality of life in patients undergoing robotic assisted laparoscopic vs open radical prostatectomy. Higher physical scores were seen in the robotic assisted laparoscopic group than the open group beginning postoperative week 1 and continuing weekly throughout the 6-week study period. Physical Component Score scores returned to baseline sooner in the robotic assisted laparoscopic group than in the open group.

The purpose was to understand the processes Hispanic parents undergo in managing postoperative care of children after routine surgical procedures. Sixty parents of children undergoing outpatient surgery were interviewed. Data were analyzed using grounded theory methodology. Parents experienced five subprocesses that comprised the overall process of caring for a child after routine surgery: (a) becoming informed; (b) preparing; (c) seeking reassurance; (d) communicating with one's child; and (e) making pain management decisions. Addressing cultural factors related to pain management in underserved families may instill greater confidence in managing pain. © 2015, Wiley Periodicals, Inc.

Prenatal and accurate perinatal diagnosis of type 2 H or ductular duplicate gallbladder.

Double gallbladder is a rare biliary anomaly. Perinatal diagnosis of the disorder has been reported in only 6 cases, and in 5 of them the diagnosis was based on ultrasound imaging only. However, the ultrasound technique alone does not provide a sufficiently precise description of cystic ducts and biliary anatomy, an information that is crucial for a correct classification and for a possible future surgery. At 21 weeks of gestational age of an uneventful pregnancy in a 38 year old primipara mother, a routine ultrasound screening detected a biliary anomaly in the fetus suggestive of a double gallbladder. A neonatal abdominal ultrasonography performed on postnatal day 2 confirmed the diagnosis. On day 12 the newborn underwent a Magnetic Resonance Cholangiopancreatography (MRCP) that clearly characterized the anatomy of the anomaly: both gallbladders had their own cystic duct and both had a separate insertion in the main biliary duct. We report a case of early prenatal suspected duplicate gallbladder that was confirmed by a neonatal precise diagnosis of a Type 2, H or ductular duplicate gallbladder, using for the first time 3D images of Magnetic resonance cholangiopancreatography in a newborn. An accurate anatomical diagnosis is mandatory in patients undergoing a possible future cholecystectomy, to avoid surgical complications or reoperations. Therefore, in case of a perinatal suspicion of a double gallbladder, neonates should undergo a Magnetic resonance cholangiopancreatography. A review of the Literature about this variant is included.

Gynecomastia associated with herniated nipples: an optimal surgical approach.

PubMed

Jaiswal, Rohit; Pu, Lee L Q

Gynecomastia is a common disorder observed in male plastic surgery patients. Treatment options may include observation, surgical excision, or liposuction techniques. Congenital herniated nipple is a more rare condition, especially in male patients. We present the case of a 12-year-old boy with bilateral gynecomastia and herniated nipple-areolar complexes. A staged repair was undertaken in this patient with grade 2 gynecomastia. The first operation was ultrasonic liposuction bilaterally, yielding 200 mL of aspirate from the left and 400 mL on the right, to correct the gynecomastia. The second procedure, performed 6 months later, was a bilateral periareolar mastopexy to repair the herniated nipple-areolar complexes. The result of the first procedure was flattened and symmetrical breast tissue bilaterally, essentially a correction of the gynecomastia. The herniated nipples were still present, however. Bilateral periareolar mastopexies were then performed with resulting reduction of the herniations. There were no complications with either procedure, and a good cosmetic result was achieved. A staged surgical approach was successful in correcting both conditions with an excellent aesthetic result and the advantage of decreased risk for nipple complications.

Objective: To introduce a novel surgical technique for correction of adult congenital webbed penis. Methods: From March 2010 to December 2011, 12 patients (age range: 14–23 years old) were diagnosed as having a webbed penis and underwent a new surgical procedure designed by us. Results: All cases were treated successfully without severe complication. The operation time ranged from 20 min to 1 h. The average bleeding volume was less than 50 ml. All patients achieved satisfactory cosmetic results after surgery. The penile curvature disappeared in all cases and all patients remained well after 1 to 3 months of follow-up. Conclusions: Adult webbed penis with complaints of discomfort or psychological pressure due to a poor profile should be indicators for surgery. Good corrective surgery should expose the glans and coronal sulcus, match the penile skin length to the penile shaft length dorsally and ventrally, and provide a normal penoscrotal junction. Our new technique is a safe and effective method for the correction of adult webbed penis, which produces satisfactory results. PMID:22949367

Simplicity and treatment of the typical cleft hand.

PubMed

Upton, J

2004-01-01

The typical cleft hand is now distinguished from symbrachydactyly. This review of the surgical treatment of 108 hands in 63 patients treated over a 28-year period concentrates upon the technical principles of surgical correction. The key to these reconstructions is a wide incision which extends from the ulnar side of the cleft around the malpositioned index finger to the thumb. This wide exposure provides clear identification of all anatomic structures within the palm. There are no tenuous flaps with narrow random pedicles. These difficult surgical corrections may often include index transposition, metacarpal and/or phalangeal osteotomies, joint releases, phalangeal ostectomies, preservation of the adductor pollicis muscle, first dorsal interosseous muscle release, syndactyly separation(s) and thumb duplication correction. Following reposition of all skeletal structures the dorsal and palmar full-thickness flaps are easily contoured to create a satisfactory first webspace. Outcomes data shows that although the pinch and grip remain weak, these hands are quite functional. It is important that the repositioned index ray not interfere with gripping and precision maneuvers between the mobile thumb and the ulnar two digits (ring and small) of the hand.

We evaluated our simulated major lung resection employing anatomically correct lung models as "off-the-job training" for video-assisted thoracic surgery trainees. A total of 76 surgeons voluntarily participated in our study. They performed video-assisted thoracic surgical lobectomy employing anatomically correct lung models, which are made of sponges so that vessels and bronchi can be cut using usual surgical techniques with typical forceps. After the simulation surgery, participants answered questionnaires on a visual analogue scale, in terms of their level of interest and the reality of our training method as off-the-job training for trainees. We considered that the closer a score was to 10, the more useful our method would be for training new surgeons. Regarding the appeal or level of interest in this simulation surgery, the mean score was 8.3 of 10, and regarding reality, it was 7.0. The participants could feel some of the real sensations of the surgery and seemed to be satisfied to perform the simulation lobectomy. Our training method is considered to be suitable as an appropriate type of surgical off-the-job training.

The physiological and psychological stress that brain tumor patients undergo during the entire surgical experience can considerably affect several aspects of their hospitalization. The purpose of this study was to examine the effects of live music therapy on quality of life indicators, amount of medications administered and length of stay for persons receiving elective surgical procedures of the brain. Subjects (N = 27) were patients admitted for some type of surgical procedure of the brain. Subjects were randomly assigned to either the control group receiving no music intervention (n = 13) or the experimental group receiving pre and postoperative live music therapy sessions (n = 14). Anxiety, mood, pain, perception of hospitalization or procedure, relaxation, and stress were measured using a self-report Visual Analog Scale (VAS) for each of the variables. The documented administration of postoperative pain medications; the frequency, dosage, type, and how it was given was also compared between groups. Experimental subjects live and interactive music therapy sessions, including a pre-operative session and continuing with daily sessions until the patient was discharged home. Control subjects received routine hospital care without any music therapy intervention. Differences in experimental pretest and posttest scores were analyzed using a Wilcoxon Matched-Pairs Signed-Rank test. Results indicated statistically significant differences for 4 of the 6 quality of life measures: anxiety (p = .03), perception of hospitalization (p = .03), relaxation (p = .001), and stress (p = .001). No statistically significant differences were found for mood (p > .05) or pain (p > .05) levels. Administration amounts of nausea and pain medications were compared with a Two-Way ANOVA with One Repeated Measure resulting in no significant differences between groups and medications, F(1, 51) = 0.03; p > .05. Results indicate no significant differences between groups for length of stay (t = .97, df = 25, p > .05). This research study indicates that live music therapy using patient-preferred music can be beneficial in improving quality of life indicators such as anxiety, perception of the hospitalization or procedure, relaxation, and stress in patients undergoing surgical procedures of the brain.

Dual pathology causing severe pulmonary hypertension following surgical repair of total anomalous pulmonary venous connection: Successful outcome following serial transcatheter interventions.

Surgical repair of total anomalous pulmonary venous connection (TAPVC) can be complicated by the development of pulmonary venous stenosis later on. In addition, the vertical vein, if left unligated, can remain patent and lead to hemodynamically significant left to right shunting. We report an infant who required transcatheter correction of both these problems after surgical repair of TAPVC.

[Update on upper eyelid blepharoplasty].

PubMed

Klingenstein, A; Hintschich, C

2018-04-01

Upper eyelid blepharoplasty is among the most frequent oculoplastic surgical procedures. It is often performed as one of the first esthetic surgical interventions by surgeons of various disciplines. While there is a high probability of happy and satisfied patients postoperatively, there are important potential surgical complications that should be prevented. This requires a careful preoperative, perioperative and postoperative approach. This synopsis presents the basic considerations concerning upper eyelid blepharoplasty to serve as practical surgical guidelines. This is a compendium of important preoperative, perioperative and postoperative contemplations derived from the medical literature, expert opinions and the authors' personal experiences. Careful examination and documentation of eyelid and periorbital findings are required in order to identify additional pathologies to dermatochalasis and plan the surgical approach accordingly. There is a trend in the literature and in expert opinions away from large tissue resection and towards volume preserving and volume reconstructing surgical techniques. Correct placement of the skin fold as well as maintaining lid symmetry are crucial points in order to achieve a natural appearance and patient satisfaction. Careful and realistic patient information, state of the art surgery including cautious tissue resection and correct symmetrical formation of the skin fold as well as postoperative assistance and availability increase the likelihood of satisfied patients after blepharoplasty.

Prospective evaluation of surgical site infection rate among patients with Mohs micrographic surgery without the use of prophylactic antibiotics.

Antibiotics may be indiscriminately given to patients undergoing Mohs micrographic surgery (MMS) for the prevention of surgical site infections, despite a low risk of infection in these patients. We sought to evaluate the rate of wound infections among patients undergoing MMS without the use of prophylactic antibiotics. We prospectively evaluated 1000 consecutive patients undergoing MMS for nonmelanoma skin cancer or modified MMS/"slow Mohs" for lentigo maligna melanoma in situ. The overall wound infection rate among 1000 patients with 1115 tumors was 0.7% (8/1115 tumors). Five (62.5%) of 8 infections occurred on the nose with an overall 1.7% (5/302) nose infection rate. Seven (87.5%) of 8 infections occurred after flap reconstruction with an overall 2.4% (7/296) flap closure infection rate. Four (50%) of 8 infections occurred in patients requiring more than one Mohs stage for tumor clearance with a 0.8% (4/487) overall infection rate in cases requiring multiple Mohs stages. Two (25%) of 8 infections had cultures positive for oxacillin-resistant Staphylococcus aureus. No wound infections occurred in cases involving the lips or ears, skin-graft closures, or below-knee or modified MMS procedures. This was a prospective single institution uncontrolled study. Rates of infections among patients undergoing MMS or modified MMS are exceedingly low. Indiscriminate use of antibiotics increases patient risk to adverse drug reactions and antibiotic resistance. Administration of antibiotics to patients undergoing MMS should be on a case-by-case basis according to the known risk factors combined with clinical judgment.

The main treatment strategies for chronic pancreatitis in young patients include therapeutic endoscopic retrograde cholangio-pancreatography (ERCP) intervention and surgical intervention. Therapeutic ERCP intervention is performed much more extensively for its minimally invasive nature, but a part of patients are referred to surgery at last. Historical and follow-up data of 21 young patients with chronic pancreatitis undergoing duodenum-preserving total pancreatic head resection were analyzed to evaluate the outcomes of therapeutic ERCP intervention and surgical intervention in this study. The surgical complications of repeated therapeutic ERCP intervention and surgical intervention were 38% and 19% respectively. During the first therapeutic ERCP intervention to surgical intervention, 2 patients developed diabetes, 5 patients developed steatorrhea, and 5 patients developed pancreatic type B pain. During the follow-up of surgical intervention, 1 new case of diabetes occurred, 1 case of steatorrhea recovered, and 4 cases of pancreatic type B pain were completely relieved. In a part of young patients with chronic pancreatitis, surgical intervention was more effective than therapeutic ERCP intervention on delaying the progression of the disease and relieving the symptoms.

New surgical procedures taking advantage of the regenerative abilities of the liver are being introduced as potential curative therapies to these patients either to provide auxiliary support while the native liver recovers or undergoes hypertrophy. For patients with hepatocellular carcinoma outside of the Milan criteria or bilobar colorectal metastases liver transplantation is not an option. Fulminant hepatic failure can be treated but requires life-long immunosuppression. These complex surgical procedures require high quality and directed imaging.

Improving Functional and Aesthetic Outcomes in Syndromic Patients With Webbed Neck Deformity: Utilizing a Staged Endoscopic-Assisted Approach to Improve the Posterior Hairline and Decrease Scar Burden.

2017-06-01

Webbed neck deformity (WND) can have significant functional and psychosocial impact on the developing child. Surgical correction can be challenging depending on the extent of the deformity, and patients often also have low posterior hairlines requiring simultaneous correction. Current surgical techniques include various methods of single-stage radical excision that often result in visible scar burden and residual deformity. There is currently no general consensus of which technique provides the best outcomes. A modified approach to WND was designed by the senior author aimed to decrease scar burden. Endoscopic-assisted fasciectomy was performed with simultaneous posterior hairline reconstruction with local tissue rearrangement camouflaged within the hair-bearing scalp. Staged surgical correction was planned rather than correction in a single operation. A retrospective review was performed to evaluate all patients who underwent this approach over a 2-year period. Two patients underwent the modified approach, a 17-year-old female with Noonan syndrome and a 2-year-old female with Turner syndrome. Both patients showed postoperative improvement in range of motion, contour of the jaw and neckline, and posterior hairline definition. Patients were found to have decreased scar burden compared with traditional techniques. A staged, combination approach of endoscopic-assisted fasciectomy and strategic local tissue reconstruction of the posterior hairline to correct WND achieves good functional and aesthetic results and good patient satisfaction. This modification should be considered when managing WND.

Heller Myotomy for Achalasia: Quality of Life Comparison of Laparoscopic and Open Approaches

PubMed Central

Katilius, Marius

2001-01-01

Background: Achalasia is a relatively rare disorder with a variety of treatment options. Although laparoscopic Heller myotomy has become the surgical treatment of choice, little data exist on the overall quality of life of patients undergoing this technique versus standard open approaches. Methods: We prospectively evaluated all patients surgically treated for achalasia by a single surgeon. Laparoscopic Heller myotomy consisted of a long (≥ 6 cm) esophageal cardiomyotomy extending at least 2 cm onto the gastric cardia, with a concomitant Dor fundoplication. Patients were evaluated preoperatively and postoperatively for symptoms and quality of life using the SF-36, a standardized, generic quality of life instrument. Results: A total of 23 patients were surgically treated: 15 patients had a planned laparoscopic procedure, with 3 conversions; 8 had planned open procedures. Dysphagia resolved in 20 of 21 patients, with 1 patient in the laparoscopic group requiring reoperation due to an inadequate gastric myotomy. Compared with preoperative scores, a statistically significant improvement occurred in the general health domain of the SF-36 (70 to 82, P = 0.04). Compared with that in patients undergoing open surgery, the laparoscopic group had better scores in the domains of physical functioning and bodily pain. Conclusions: Laparoscopic Heller myotomy has comparable success to open Heller myotomy, and causes less early detriment to quality of life. This should be the primary treatment in all fit surgical patients with achalasia. PMID:11548827

Randomized Trial Comparing Amniotic Membrane Transplantation with Lamellar Corneal Graft for the Treatment of Corneal Thinning.

PubMed

de Farias, Charles C; Allemann, Norma; Gomes, José Á P

2016-04-01

There are few studies comparing different surgical procedures for the treatment of corneal thinning. Lamellar corneal transplantation (LCT) has been reported to be efficient, but its results can be jeopardized by allograft rejection, opacification, or high astigmatism. Amniotic membrane transplantation (AMT) has been considered a good alternative, but it is not as resistant as LCT and the tissue can be reabsorbed after surgery. A prospective, randomized, interventional, and comparative study of consecutive patients with corneal thinning over 6 months was performed. Ophthalmological examination was performed before transplant surgery and then repeated 1, 7, 15, 30, 90, and 180 days after surgery and ultrasound biomicroscopy was performed before and then 30, 90, and 180 days after surgery to assess corneal thinning. Herpes simplex infection was the main cause of corneal thinning (9 eyes), followed by surgery (cataract, glaucoma, 5 cases), rheumatoid arthritis (1), chemical burn (1), perforating trauma (1), previous band keratopathy treatment (1), and Stevens-Johnson syndrome (1). Although all patients showed significant increase in final thickness in the area of thinning, it was higher in those submitted to LCT at 180 days postoperatively. Regardless of the surgical technique, all patients showed epithelialization. Patients undergoing AMT showed an 89% decrease in neovascularization. Final corrected distance visual acuity was better in patients submitted to AMT. LCT proved to be the best option for treating corneal thinning. AMT represents an alternative that allows good visual recovery but does not restore corneal thickness as efficiently as LCT.

A systematic approach to the surgical treatment of gynaecomastia.

Fruhstorfer, B H; Malata, C M

2003-04-01

Numerous techniques have been described for the correction of gynaecomastia, and the surgeon is faced with a wide range of excisional and liposuction procedures. There is a paucity of literature describing an integrated approach to the management of this condition and the roles of the different treatment modalities. A review of all gynaecomastia patients operated on by one surgeon over a 2-year period was undertaken. Patient satisfaction was assessed using a linear analogue scale with a maximum score of 10. In total, 48 breasts in 29 patients were treated--31 breasts by liposuction alone (19 by conventional liposuction, 12 by ultrasound-assisted liposuction), eight breasts by liposuction and open excision, and nine breasts by liposuction, open excision and skin reduction (concentric or Lejour mastopexy). There were no early postoperative complications, such as haematoma, seroma or infection, and 91% of patients were very satisfied (score: 8-10) with their cosmetic outcome. The most frequently encountered complication was a residual subareolar lump (five breasts), all in patients treated by conventional liposuction alone. In order to avoid the common complication of an uncomfortable residual subareolar nodule, the threshold for open excision in patients undergoing conventional liposuction should be low. Ultrasound-assisted liposuction extends the role of liposuction in gynaecomastia patients. Although skin excess remains a challenge, it can be satisfactorily managed without excessive scarring. A practical approach to the surgical management of gynaecomastia, which takes into account breast size, consistency, skin excess and skin quality, is proposed.

Rational approach to transfusion in liver transplantation.

Saner, Fuat H; Abeysundara, Lasitha; Hartmann, Matthias; Mallett, Susan V

2018-03-01

For over 50 years patients with liver cirrhosis were considered to be at markedly increased risk of bleeding. This dogma was seemingly supported by abnormalities in standard laboratory tests (SLTs), such as the prothrombin time, that were interpreted as indicating a bleeding diathesis. However, publications from the last decade have revealed SLTs to be poor predictors of bleeding and it is now understood that stable patients with cirrhosis have a rebalanced haemostatic system and preserved thrombin generation. Viscoelastic tests (VETs), such as ROTEM® or TEG™ allow dynamic assessment of the entire coagulation process and provide a better illustration of the interactions between pro- and anticoagulants as well as platelets. Despite their documented success in reducing transfusion rates in liver transplantation more than 30 years ago, the adoption of VETs has been met with some resistance and has only recently gained significant momentum. Bleeding risk should be assessed in every patient undergoing invasive intervention and must consider markers of disease severity, underlying coagulation incompetence, anaemia and surgical factors. The recognition that bleeding in this patient cohort is predominantly linked to mechanistic factors such as portal hypertension, rather than primary coagulopathy, has led to a paradigm shift in their perioperative management. Cognizant of their detrimental effect, the use of large volumes of fresh frozen plasma to correct derangements in SLTs has given way to more refined haemostatic management with specific factor concentrates guided by VETs, coupled with measures to minimize portal venous pressure and meticulous surgical hemostasis.

Pectus excavatum (PE) can be associated with congenital and acquired cardiac disorders that also require surgical repair. The timing and specific surgical technique for repair of PE remains controversial. The present study reports the experience of combined repair of PE and open heart surgery at Johns Hopkins Hospital. A retrospective case review was conducted of all patients who presented for repair of PE deformity while undergoing concurrent open heart surgery from 1998 through 2011. A total of 9 patients met inclusion criteria. All patients had a connective tissue disorder. Repair of PE was performed by modified Nuss technique after completion of the cardiac procedure, performed through a median sternotomy. Open heart procedures were either aortic root replacement or mitral valvuloplasty. Eight patients had bar removal after an average period of 30.3 months. No PE recurrence, bar displacement, or upper sternal depression was reported in 7 patients. Postoperatively, 1 patient exhibited pectus carinatum after a separate spinal fusion surgery for scoliosis. One patient died of unrelated cardiac complications before bar removal. Simultaneous repair of PE and open heart surgery is safe and effective. We recommend that the decision to perform a single-stage versus a multistage procedure should be reserved until after the cardiac procedure has been completed. In such cases, the Nuss technique allows for correction of the pectus deformity with good long-term cosmetic and functional results. Copyright © 2013 The Society of Thoracic Surgeons.

Surgical attire is intended to protect both patients and perioperative personnel. AORN published the "Recommended practices for surgical attire" to guide perioperative RNs in establishing protocols for selecting, wearing, and laundering surgical attire. Perioperative RNs should work with vendors and managers to ensure appropriate surgical attire is available, model the correct practices for donning and wearing surgical attire, and teach team members about evidence-based practices. The recommendation that surgical attire not be home laundered is supported by evidence that perioperative nurses can share with their colleagues and managers to help support appropriate practices. Hospital and ambulatory surgery center scenarios have been included as examples of appropriate execution of these recommended practices. Copyright © 2012 AORN, Inc. Published by Elsevier Inc.

Disposable surgical face masks for preventing surgical wound infection in clean surgery.

PubMed

Lipp, Allyson; Edwards, Peggy

2014-02-17

Surgical face masks were originally developed to contain and filter droplets containing microorganisms expelled from the mouth and nasopharynx of healthcare workers during surgery, thereby providing protection for the patient. However, there are several ways in which surgical face masks could potentially contribute to contamination of the surgical wound, e.g. by incorrect wear or by leaking air from the side of the mask due to poor string tension. To determine whether disposable surgical face masks worn by the surgical team during clean surgery prevent postoperative surgical wound infection. We searched The Cochrane Wounds Group Specialised Register on 23 October 2013; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE; and EBSCO CINAHL. Randomised controlled trials (RCTs) and quasi-randomised controlled trials comparing the use of disposable surgical masks with the use of no mask. Two review authors extracted data independently. Three trials were included, involving a total of 2113 participants. There was no statistically significant difference in infection rates between the masked and unmasked group in any of the trials. From the limited results it is unclear whether the wearing of surgical face masks by members of the surgical team has any impact on surgical wound infection rates for patients undergoing clean surgery.

Different etiologies for recurrent pregnancy loss have been identified, among them are: anatomical, endocrine, genetic, chromosomal and thrombophilia pathologies. To assess medical and obstetric characteristics, and pregnancy outcomes, among women with uterine abnormalities and recurrent pregnancy loss (RPL). This study also aims to assess the impact of uterine anatomic surgical correction on pregnancy outcomes. A retrospective case control study of 313 patients with two or more consecutive pregnancy losses followed by a subsequent (index) pregnancy. Anatomic abnormalities were detected in 80 patients. All patients were evaluated and treated in the RPL clinic at Soroka University Medical Center. Out of 80 patients with uterine anatomic abnormalities, 19 underwent surgical correction, 32 did not and 29 had no clear record of surgical intervention, and thus were excluded from this study. Women with anatomic abnormalities had a higher rate of previous cesarean section (18.8% vs. 8.6%, P=0.022), tended to have a lower number of previous live births (1.05 vs. 1.37, P=0.07), and a higher rate of preterm delivery (22.9% vs. 10%, P=0.037). Using multivariate logistic regression analysis, anatomic abnormality was identified as an independent risk factor for RPL in patients with previous cesarean section after controlling for place of residence, positive genetic/autoimmune/endocrine workup, and fertility problems (OR 7.22; 95% CI 1.17-44.54, P=0.03). Women suffering from anatomic abnormalities tended to have a higher rate of pregnancy loss compared to those without anatomic abnormalities (40% vs. 30.9%, P=0.2). The difference in pregnancy loss rate among women who underwent surgical correction compared to those who did not was not statistically significant. In patients with previous cesarean section, uterine abnormality is an independent risk factor for pregnancy loss. Surgical correction of uterine abnormalities among RPL patients might have the potential to improve live birth rate.

A study was undertaken to assess whether results of laser vision correction with the LADARVISION 193-nm excimer laser (Alcon-Autonomous technologies) can be improved with the use of wavefront analysis generated by a proprietary system including a Hartman-Schack sensor and expressed using Zernicke polynomials. A total of 82 eyes underwent LASIK in several centers with an improved algorithm, using the CustomCornea system. A subgroup of 48 eyes of 24 patients was randomized so that one eye undergoes conventional treatment and one eye undergoes treatment based on wavefront analysis. Treatment parameters were equal for each type of refractive error. 83% of all eyes had uncorrected vision of 20/20 or better and 95% were 20/25 or better. In all groups, uncorrected visual acuities did not improve significantly in eyes treated with wavefront analysis compared to conventional treatments. Higher order aberrations were consistently better corrected in eyes undergoing treatment based on wavefront analysis for LASIK at 6 months postop. In addition, the number of eyes with reduced RMS was significantly higher in the subset of eyes treated with a wavefront algorithm (38% vs. 5%). Wavefront technology may improve the outcomes of laser vision correction with the LADARVISION excimer laser. Further refinements of the technology and clinical trials will contribute to this goal.

To investigate the frequency, source, and risk factors of intraoperative (IO) surgeon and patient bacterial contamination during clean orthopedic surgeries, and to investigate the relationship between IO contamination and surgical site infection (SSI) in dogs. Prospective clinical study. Client-owned dogs undergoing stifle surgery (n = 100). IO cultures were taken in each case from surgical foot wrap, peri-incisional skin, surgical gloves, and the surgical team's hands. The environment (operating room [OR] lights, computers, scrub sink faucet, anesthesia gurney, and radiology table) was sampled every 5 months. Bacteria were identified and the contamination of each case was categorized. All gloves from the surgical team were collected and tested for perforations using a water infusion test. Cases were followed for at least 8 weeks to determine the presence or absence of SSI. Perioperative variables were evaluated for association with IO contamination and SSI. Bacterial isolates were yielded from 81% of procedures from 1 or more sources; 58% had positive hand cultures, 46% had positive glove cultures, 23% had positive patient skin cultures, and 12% had positive foot wrap cultures. Staphylococcus spp. was the most commonly recovered bacteria. There was no apparent association between IO contamination and SSI. The highest level of environmental contamination was associated with the scrub sink faucet, followed by the radiology table, anesthesia gurney, and OR computers. The IO glove perforation rate was 18%. Clean orthopedic procedures commonly had clinically insignificant bacterial contamination. In our study, bacteria responsible for SSI did not appear to colonize the patient in the OR. © Copyright 2016 by The American College of Veterinary Surgeons.

Objective-To identify variables associated with prognosis in dogs undergoing surgical excision of anal sac apocrine gland adenocarcinomas (ASACs) with and without adjunctive chemotherapy. Design-Retrospective case series. Animals-42 dogs with ASACs. Procedures-Information on signalment, clinical signs, diagnostic procedures, surgical procedures, adjunctive therapies, survival time, and disease-free interval was obtained from the medical records. Results-Survival time was significantly associated with the presence of sublumbar lymphadenopathy and sublumbar lymph node extirpation, with median survival time significantly shorter for dogs with sublumbar lymphadenopathy (hazard ratio, 2.31) than for those without and for dogs that underwent lymph node extirpation (hazard ratio, 2.31) than for those that did not. Disease-free interval was significantly associated with the presence of sublumbar lymphadenopathy, lymph node extirpation, and administration of platinum-containing chemotherapeutic agents, with median disease-free interval significantly shorter for dogs with sublumbar lymphadenopathy (hazard ratio, 2.47) than for those without, for dogs that underwent lymph node extirpation (hazard ratio, 2.47) than for those that did not, and for dogs that received platinum-containing chemotherapeutic agents (hazard ratio, 2.69) than for those that did not. Survival time and disease-free interval did not differ among groups when dogs were grouped on the basis of histopathologic margins (complete vs marginal vs incomplete excision). Conclusions and Clinical Relevance-Results suggested that in dogs with ASAC undergoing surgical excision, the presence of sublumbar lymphadenopathy and lymph node extirpation were both negative prognostic factors. However, completeness of surgical excision was not associated with survival time or disease-free interval.

This paper illustrates the results of surgical correction in 11 cases with orbital deformities such as periorbital deficiency after orbitotomy for retinoblastoma and orbital malposition after facial trauma. EH composite material, mixture of hydroxyapatite and epoxide acrylate maleic resin in constant proportion, was used as a good bone graft substitute in all 11 cases. This material was easier to be molded during surgery, safe to human body, had no toxic effects, no irritation and no implant-related complications. The early results obtained in these patients are encouraging.

Three dogs presented for evaluation of acute onset tachypnoea and dyspnoea following episodes of vomiting and/or regurgitation. Thoracic radiographs were suggestive of a gastro-oesophageal intussusception in all three dogs; one dog also showed evidence of aspiration pneumonia. All three dogs underwent surgical correction with a bilateral incisional gastropexy. All dogs recovered from anaesthesia uneventfully and were discharged from the hospital 3 days after presentation. Persistent megaoesophagus was evident in all three dogs, and they are being chronically managed with a strict feeding regime and pro-motility agents. © 2015 British Small Animal Veterinary Association.

2011-01-01

The natural history of congenitally corrected transposition of the great arteries is of clinical/surgical importance once the fetus is born without heart block or signs of heart failure. Without significant tricuspid valve malformation, associated defects such as ventricular septal defect and left ventricular outflow obstruction can be repaired surgically. The mortality and long-term outcome appear to be linked strongly with the severity of tricuspid valve regurgitation. Some patients with an intact ventricular septum and no right ventricular dysfunction will live long lives without detection, and some women will successfully complete pregnancy.

Swan neck and boutonniere deformities of the proximal interphalangeal (PIP) joint are challenging to treat. In a swan neck deformity, the PIP joint is hyperextended with flexion at the distal interphalangeal (DIP) joint. In a boutonniere deformity, there is flexion the PIP joint with hyperextension of the DIP joint. When the deformities are flexible, treatment begins with splinting. However, when the deformity is fixed, serial casting or surgery is often necessary to restore joint motion before surgical correction. Many surgical techniques have been described to treat both conditions. Unfortunately, incomplete correction and deformity recurrence are common. Published by Elsevier Inc.

There are little primary data available on the delivery or quality of surgical treatment in rural sub-Saharan African hospitals. To initiate a quality improvement system, we characterized the existing data capture at a Ugandan Regional Referral Hospital. We examined the surgical ward admission (January 2008-December/2011) and operating theater logbooks (January 2010-July 2011) at Mbarara Regional Referral Hospital. There were 6346 admissions recorded over three years. The mean patient age was 31.4 ± 22.3 years; 29.8 % (n = 1888) of admissions were children. Leading causes of admission were general surgical problems (n = 3050, 48.1 %), trauma (n = 2041, 32.2 %), oncology (n = 718, 11.3 %) and congenital condition (n = 193, 3.0 %). Laparotomy (n = 468, 35.3 %), incision and drainage (n = 188, 14.2 %) and hernia repair (n = 90, 6.8 %) were the most common surgical procedures. Of 1325 operative patients, 994 (75 %) had an ASA I-II score. Of patients undergoing 810 procedures booked as non-elective, 583 (72 %) had an ASA "E" rating. Records of 41.3 % (n-403/975) of patients age 5 years or older undergoing non-obstetric operations were missing from the ward logbook. Missing patients were younger (25 [13,40] versus 30 [18,46] years, p = 0.002) and had higher ASA scores (ASA III-V 29.0 % versus 18.9 %, p < 0.001) than patients recorded in the logbbook; there was no diffence in gender (male 62.8 % versus 67.0 %, p = 0.20). The hospital records system measures surgical care, but improved data capture is needed to determine outcomes with sufficient accuracy to guide and record expansion of surgical capacity.

Tricuspid regurgitation (TR) presents as either primary valve pathology or secondary to pulmonary or left-sided heart disease. Severe TR portends a worse prognosis independent of age, right ventricular size and function, severe left ventricular dysfunction, and increased pulmonary arterial pressures. Surgical treatment for TR has mostly been limited to patients undergoing mitral valve repair since those at high surgical risk are not candidates for traditional TR surgery. For these patients, minimally invasive techniques could be of great benefit, yet these techniques have been slow to develop because of the various anatomic and physiological aspects of the tricuspid valve apparatus. Several promising new techniques are currently undergoing clinical investigation, including caval valve implantation, percutaneous tricuspid annuloplasty techniques (Trialign, TriCinch, Cardioband), edge-to-edge repair with the MitraClip system, the FORMA device, and the GATE tricuspid Atrioventricular Valved Stent. Further evaluation of their safety and long-term efficacy is warranted prior to commercial approval and widespread adoption. PMID:29743996

The Perioperative Surgical Home: Improving the Value and Quality of Care in Total Joint Replacement.

PubMed

Chimento, George F; Thomas, Leslie C

2017-09-01

The perioperative surgical home (PSH) is a patient-centered, physician-led, multidisciplinary care pathway developed to deliver value-based care based on shared decision-making. Physician and hospital reimbursement will be tied to providing quality care at lower cost, and the PSH model has been used in providing care to patients undergoing lower extremity arthroplasty. The purpose of this review is to discuss the rationale, definition, development, current state, and future direction of the PSH. The PSH model guides the patient throughout the pre and perioperative process and into the postoperative phase. It has been shown in multiple studies to decrease length of stay, improve functional outcomes, allow more home discharges, and lower costs. There is no increase in complications or readmission rates. The PSH pathway is a safe and effective method of providing value-based care to patients undergoing hip and knee arthroplasty.

Postoperative nausea and vomiting (PONV) is a common source of patient discomfort and decreased satisfaction. Aromatherapy has been identified as a complementary modality for the prevention and management of PONV. The purpose of this study was to assess the effect of aromatherapy on the severity of postoperative nausea (PON) in women undergoing surgical procedures in the postanesthesia care unit. Women complaining of PON received traditional antiemetics, inhalation of peppermint oil, or saline vapor. A visual analog scale was used to rate nausea at the first complaint; at 5 minutes after intervention; and, if nausea persisted, at 10 minutes after intervention. At both 5 and 10 minutes, statistical analysis showed no significant differences between intervention and nausea rating. Obtaining eligible subjects was challenging. Although many women consented, most received intraoperative antiemetics and did not report nausea postoperatively. Copyright © 2012 American Society of PeriAnesthesia Nurses.

An Interdisciplinary Education Initiative to Promote Blood Conservation in Cardiac Surgery.

PubMed

Goda, Tamara S; Sherrod, Brad; Kindell, Linda

Transfusion practices vary extensively for patients undergoing cardiac surgical procedures, leading to high utilization of blood products despite evidence that transfusions negatively impact outcomes. An important factor affecting transfusion practice is recognition of the importance of teams in cardiac surgery care delivery. This article reports an evidenced-based practice (EBP) initiative constructed using the Society of Thoracic Surgery (STS) 2011 Blood Conservation Clinical Practice Guidelines (CPGs) to standardize transfusion practice across the cardiac surgery team at a large academic medical center. Project outcomes included: a) Improvement in clinician knowledge related to the STS Blood Conservation CPGs; and b) Decreased blood product utilization for patients undergoing cardiac surgical procedures. Participants' scores reflected an improvement in the overall knowledge of the STS CPGs noting a 31.1% (p = 0.012) increase in the number of participants whose practice reflected the Blood Conservation CPGs post intervention. Additionally, there was a reduction in overall blood product utilization for all patients undergoing cardiac surgery procedures post intervention (p = 0.005). Interdisciplinary education based on the STS Blood Conservation CPGs is an effective way to reduce transfusion practice variability and decrease utilization of blood products during cardiac surgery.

The aim of this systematic review and meta-analysis was to evaluate the risk of surgical infection, alveolar osteitis, and adverse effects using systemic metronidazole in comparison with placebo in healthy patients undergoing third molar surgery. The eligible reports were identified from diverse science sources. Clinical trials meeting the inclusion and exclusion criteria and an acceptable Oxford Quality Score were included in this study. The evaluation of risk was done using the Risk Reduction Calculator and Review Manager 5.3., from the Cochrane Library. A significant risk reduction was assumed when the upper limit of the 95% confidence intervals was <1 and the lower limit did not cross zero (negative number) alongside a p value of <0.05 for the overall test. Data of 667 patients from five clinical trials were used for the assessment of risk. Our analysis showed no reduction of the risk of infection or dry socket in patients receiving metronidazole compared to whom took placebo. Meanwhile, the adverse effects did not exhibit a difference between the studied groups. The routine use of systemic metronidazole to prevent surgical site infection and/or dry socket in healthy patients undergoing third molar surgery is not recommended.

To evaluate the feasibility and the efficiency of intraoperative ex vivo ultrasound of resection margins in patients undergoing partial nephrectomy by urologist. Patients undergoing partial nephrectomy from July 2010 to November 2012 for T1-T2 renal tumors were included in analysis. Tumor margin status was immediately determined by ex vivo ultrasound done by the surgeon himself. Results were compared with margin status on definitive pathological evaluation. A total of 26 men and 15 women with a median age of 61 (30-82) years old were included in analysis. Intraoperative ex vivo ultrasound revealed negative surgical margins in 38 cases and positive margins in two. Final pathological results revealed negative margins in all except one case. Ultrasound sensitivity and specificity were 100% and 97%, respectively. Mean ultrasound duration was 1minute±1. Mean tumor and margin sizes were 3.4±1.8cm and 2.38±1.76mm, respectively. Intraoperative ex vivo ultrasound of resection margins in patients undergoing partial nephrectomy by a urologist seemed to be feasible, efficient and easy. Copyright © 2013 Elsevier Masson SAS.

Chest physical therapy: comparative efficacy of preoperative and postoperative in the elderly.

PubMed

Castillo, R; Haas, A

1985-06-01

Although chest physical therapy (PT) immediately after surgery lowers the risk of postoperative pulmonary complications, several reports indicate preoperative chest PT results in further improvement. This study compares the effects of initiating chest PT either before and/or after chest surgery in patients over age 65. We studied two groups: 130 patients (the PRE group) undergoing both pre- and postoperative therapy and 150 patients (the POST group) undergoing only postoperative therapy, dividing them into four surgical subgroups: lung, cardiac and other thoracic surgery, upper abdominal, and lower abdominal (considered low risk compared with the other three). Overall complication rates and atelectasis rates were significantly lower in the PRE high-risk subgroups. PRE and POST pneumonia rates, however, were statistically equivalent in all surgical subgroups. Since the low rate of pulmonary complications for PRE-group patients undergoing thoracic or upper abdominal procedures is comparable to that for PRE-group therapy in much younger populations, advanced age alone does not appear to be a significant risk factor. The lack of effect on incidence of pneumonia indicates that preoperative chest PT only counters the altered pulmonary mechanics responsible for atelectasis, but has no effect on pulmonary complications due to infection.

Three-column osteotomy surgery versus standard surgical management for the correction of adult spinal deformity: a cohort study.

The aim of this study was to analyze and compare the surgical data, clinical outcomes, and complications between three-column osteotomy (3-COS) and standard surgical management (SSM) for the treatment of adult spine deformity (ASD). A total of 112 patients who underwent consecutive 3-COS (n = 48) and SSM (n = 64) procedures for ASD correction at a single institution from 2001 to 2011 were reviewed in this study. The outcomes were assessed using the Scoliosis Research Society (SRS)-22 scores. The complications of patients with 3-COS and SSM were also compared. No significant differences were found in patient characteristics between SSM and 3-COS groups. Surgical data and radiographic parameters showed that the patients of the 3-COS group suffered more severe ASD than those of the SSM group. The distribution of surgical complications revealed that SSM group underwent more complications than 3-COS groups with no significant differences. At final follow-up, the total SRS-22 score of SSM was not significant between pre-operation and post-operation. However, the total SRS-22 score of 3-COS at final follow-up was significantly higher than pre-operation. For severe ASD patients with high grade pelvic incidence (PI), pelvic tilt (PT), and PI/lumbar lordosis (LL) mismatch and who have subjected to spine surgeries more than twice before, 3-COS might be more effective than SSM in improving the clinical outcomes. However, due to the higher reoperation rate of 3-COS, SSM may be more appropriate than SSM for correcting the not serious ASD patients.

One and a half ventricular repair as an alternative for hypoplastic right ventricle.

Maluf, Miguel Angel; Carvalho, Antonio Carlos; Carvalho, Werther Brunow

2010-01-01

Patients with complex congenital heart disease, characterized by right ventricle hypoplasia, had a palliative surgical option with one and a half ventricular repair. From July 2001 to March 2009, nine patients (mean age 5.2 years, range 3 to 9 years) with hypoplastic right ventricle, underwent correction with one and a half ventricle technique. Preoperative diagnoses included: pulmonary atresia with intact ventricular septum, in six and Ebstein's anomaly, in three cases. Six patients had bidirectional cavo-pulmonary shunt (Glenn operation) previously. The surgical approach was performed with cardiopulmonary bypass to correct intracardiac defects: atrial septal defect closure (nine cases); right ventricle outlet tract reconstruction with porcine pulmonary prosthesis (seven cases); tricuspid valvuloplasty (three cases). There was one (11.1%) hospital death. All the patients left the hospital in good clinical conditions. One patient presented pulmonary stenosis at distal prosthesis anastomosis and needed surgical correction. There was one (12.5%) late deaths after reoperation. At mean follow-up of 39.8 months (range 16 months to 8.4 years) seven patients are alive in functional class I (NYHA). Surgical treatment of congenital cardiac anomalies in the presence of a hypoplastic right ventricle by means of one and a half ventricle repair has the advantages of reducing the surgical risk of biventricular repair compared to the Fontan circulation; it maintains a low right atrium pressure, a pulsatile pulmonary blood flow and improves the systemic oxygen saturation with short and medium-term promising results. Longer follow-up is needed to prove the efficacy of such a repair in the long term.

2010-12-01

Dupuytren's disease is one of the fibro-proliferative conditions affecting the palmar and digital fascia. This disease has been known to surgeons and treated by them for at least 200 years. Dupuytren's disease is very common in Northern Europe and also in countries inhabited by immigrants from Northern Europe. Dupuytren's contracture is stated to be uncommon in Indian subcontinent and very little has been written about this disease in India. The authors have however come across 30 patients with Dupuytren's contracture and they are the subject of this paper, with special emphasis on its surgical correction and complications of surgical treatment. Patients were categorized into stages I, II and III as per the severity of disease. Regional fasciectomy was performed in 90% of the patients and extensive fasciectomy in 10% of patients. Most of wounds were closed by primary closure with z-plasty. In rest of the patients free skin grafts were used to close the wound, when primary closure was not possible. The patients were followed up regularly for 5 years and the results of surgical treatment were categorized into excellent, good, fair and poor. The results were excellent in 23 patients (76.66%), good in six patients (20%) and fair in one patient (3.33%). Post operative edema and some stiffness was seen in two patients. Wound infection was seen in one patient and haematoma in one patient. The correct surgical technique and meticulous post operative care is needed to achieve higher rates of correction and to limit the complications and recurrence.

The correct and timely referral of patients, from peripheral hospitals, without specialized surgical care, namely in hand surgery, like Plastic Surgery or Orthopedics is of crucial importance. The authors report the case of a patient that presents in the Plastic Surgery Department with a chronic infection of the hypothenar eminence of the right hand. The clinical history suggests the persistence of a foreign body, despite two previous surgical procedures for removal, performed in the residence hospital. Surgical exploration was performed and the foreign body was removed without complications. The intent of this presentation is to alert for the importance of the timely referral of patients that can benefit of specialized care, namely of plastic surgery, when this is no possible in the residence hospital, in view of better health care and better patient treatment.

Protocol for concomitant temporomandibular joint custom-fitted total joint reconstruction and orthognathic surgery utilizing computer-assisted surgical simulation.

Movahed, Reza; Teschke, Marcus; Wolford, Larry M

2013-12-01

Clinicians who address temporomandibular joint (TMJ) pathology and dentofacial deformities surgically can perform the surgery in 1 stage or 2 separate stages. The 2-stage approach requires the patient to undergo 2 separate operations and anesthesia, significantly prolonging the overall treatment. However, performing concomitant TMJ and orthognathic surgery (CTOS) in these cases requires careful treatment planning and surgical proficiency in the 2 surgical areas. This article presents a new treatment protocol for the application of computer-assisted surgical simulation in CTOS cases requiring reconstruction with patient-fitted total joint prostheses. The traditional and new CTOS protocols are described and compared. The new CTOS protocol helps decrease the preoperative workup time and increase the accuracy of model surgery.

Optimal surgical management of severe tricuspid regurgitation in cardiac transplant patients.

Severe tricuspid regurgitation (TR) with signs of right-sided heart failure is rare after orthotopic heart transplantation (OHT). In some instances, this condition will require surgical correction using reconstructive surgery or prosthetic valve replacement. Repair techniques of atrioventricular valves are now well described. However, the results of the different surgical procedures in this setting have not been widely reported and may depend on the type of valvular dysfunction and lesions present. Herein we report our experience in a group of patients requiring surgical correction of symptomatic severe TR after OHT. We reviewed our transplant experience during the period from July 1992 to July 1999 (n = 138 cardiac transplants). Eight patients (5.8%) developed symptomatic severe TR requiring surgical correction after a mean duration of 21 months after OHT. Patients were divided into 2 groups based on the mechanism of regurgitation using Carpentier's functional classification. In Group 1 (n = 4), the mechanism of tricuspid regurgitation was Carpentier's Type I, secondary to annular dilation. In Group 2 (n = 4) the mechanism of TR was leaflet prolapse (Type II), due to chordal rupture after biopsy injury. Initially, tricuspid valve integrity was surgically restored in all 8 patients with either valve repair (n = 6) or replacement (n = 2). In Group 1, 2 patients underwent valve repair using a ring annuloplasty and 2 patients underwent valve replacement with a bioprosthetic valve (n = 1) or pulmonary allograft (n = 1). In Group 2, all patients underwent valve repair using a variety of techniques in combination with tricuspid annuloplasty. During the follow-up period, 3 of the 6 (50%) primary repairs (1 patient in Group 1 and 2 in Group 2) failed and required replacement with a bioprosthesis at 8 days, 14 days and 4 years, respectively. The pulmonary allograft failed secondary to valvular stenosis and was replaced with a bioprosthesis after 10 months. Overall, no failures occurred in any of the 5 bioprosthetic valves placed at the primary operation (n = 1) or after failed tricuspid repair/pulmonary allograft (n = 4), after a mean follow-up of 55 months. TR requiring surgical correction after OHT is a rare condition and requires a tailored surgical strategy. This strategy should take into account the mechanism of valve dysfunction and specific valvular lesions. In patients with Type I dysfunction secondary to annular dilation, valve repair with a remodeling annuloplasty should be performed; however, in the presence of any residual TR on transesophageal echocardiography (TEE) at the completion of cardiopulmonary bypass (CPB), a valve replacement with a bioprosthesis is warranted during the same procedure. In patients with Type II dysfunction with leaflet prolapse and biopsy-induced chordal injury, a bioprosthetic valve replacement seems a reliable surgical option.

Robotic technological aids in esophageal surgery.

Robotic technology is an emerging technology that has been developed in order to overcome some limitations of the standard laparoscopic approach, offering a stereoscopic three-dimensional visualization of the surgical field, increased maneuverability of the surgical tools with consequent increased movement accuracy and precision and improved ergonomics. It has been used for the surgical treatment of most benign esophageal disorders. More recently, it has been proposed also for patients with operable esophageal cancer. The current evidence shows that there are no real benefits of the robotic technology over conventional laparoscopy in patients undergoing a fundoplication for gastroesophageal reflux disease (GERD), hiatal closure for giant hiatal hernia, or Heller myotomy for achalasia. A few small studies suggest potential advantages in patients undergoing redo surgery for failed fundoplication or Heller myotomy, but large comparative studies are needed to better clarify the role of the robotic technology in these patients. Robot-assisted esophagectomy seems to be safe and effective in selected patients; however, there are no data showing superiority of this approach over both conventional laparoscopic and open surgery. The short-term and long-term oncologic results of ongoing randomized controlled trials (RCTs) are awaited to validate this approach for the treatment of esophageal cancer.

Controlled invasive mechanical ventilation strategies in obese patients undergoing surgery.

2017-06-01

The obesity prevalence is increasing in surgical population. As the number of obese surgical patients increases, so does the demand for mechanical ventilation. Nevertheless, ventilatory strategies in this population are challenging, since obesity results in pathophysiological changes in respiratory function. Areas covered: We reviewed the impact of obesity on respiratory system and the effects of controlled invasive mechanical ventilation strategies in obese patients undergoing surgery. To date, there is no consensus regarding the optimal invasive mechanical ventilation strategy for obese surgical patients, and no evidence that possible intraoperative beneficial effects on oxygenation and mechanics translate into better postoperative pulmonary function or improved outcomes. Expert commentary: Before determining the ideal intraoperative ventilation strategy, it is important to analyze the pathophysiology and comorbidities of each obese patient. Protective ventilation with low tidal volume, driving pressure, energy, and mechanical power should be employed during surgery; however, further studies are required to clarify the most effective ventilation strategies, such as the optimal positive end-expiratory pressure and whether recruitment maneuvers minimize lung injury. In this context, an ongoing trial of intraoperative ventilation in obese patients (PROBESE) should help determine the mechanical ventilation strategy that best improves clinical outcome in patients with body mass index≥35kg/m 2 .

Comfort and hope have been identified as important components in the care of perianesthesia patients. The purpose of this study was to explore the relationship between comfort and hope in the preanesthesia stage in patients undergoing surgery. A descriptive cross-sectional survey was conducted with 191 surgical patients. Data were collected using the Perianesthesia Comfort Questionnaire and Herth Hope Index. Direct and significant relationships were observed between comfort and hope (P≤.001, r=0.65). Also, significant relationships were observed between educational level and marital status with comfort (P≤.01). The relationship between educational level and hope was significant (P≤.001). Significant relationships were also observed between gender and marital status with hope (P≤.01). Overall, this study showed that a significant relationship exists between comfort and hope. Additionally, some demographic characteristics influenced comfort and hope in these patients. Health care providers should arrange the environment in a way that allows the surgical patients to experience comfort and hope and recognize the impact of personal characteristics when caring for surgical patients, particularly in the preanesthesia stage.

2013-01-01

Acute surgical patients are particularly vulnerable to human error. The Acute Physiological Support Team (APST) was created with the twin objectives of identifying high-risk acute surgical patients in the general wards and reducing both the incidence of error and impact of error on these patients. A number of error taxonomies were used to understand the causes of human error and a simple risk stratification system was adopted to identify patients who are particularly at risk of error. During the period November 2012-January 2013 a total of 101 surgical patients were cared for by the APST at Edendale Hospital. The average age was forty years. There were 36 females and 65 males. There were 66 general surgical patients and 35 trauma patients. Fifty-six patients were referred on the day of their admission. The average length of stay in the APST was four days. Eleven patients were haemo-dynamically unstable on presentation and twelve were clinically septic. The reasons for referral were sepsis,(4) respiratory distress,(3) acute kidney injury AKI (38), post-operative monitoring (39), pancreatitis,(3) ICU down-referral,(7) hypoxia,(5) low GCS,(1) coagulopathy.(1) The mortality rate was 13%. A total of thirty-six patients experienced 56 errors. A total of 143 interventions were initiated by the APST. These included institution or adjustment of intravenous fluids (101), blood transfusion,(12) antibiotics,(9) the management of neutropenic sepsis,(1) central line insertion,(3) optimization of oxygen therapy,(7) correction of electrolyte abnormality,(8) correction of coagulopathy.(2) CONCLUSION: Our intervention combined current taxonomies of error with a simple risk stratification system and is a variant of the defence in depth strategy of error reduction. We effectively identified and corrected a significant number of human errors in high-risk acute surgical patients. This audit has helped understand the common sources of error in the general surgical wards and will inform on-going error reduction initiatives. Copyright © 2013 Surgical Associates Ltd.

Prevalence of Chronic Gastritis or Helicobacter pylori Infection in Adolescent Sleeve Gastrectomy Patients Does Not Correlate with Symptoms or Surgical Outcomes.

In adults undergoing gastric bypass surgery, it is routine practice to perform pre-operative testing for Helicobacter pylori infection. Evidence suggests that infection impairs anastomotic healing and contributes to complications. There currently are no data for adolescents undergoing bariatric procedures. Despite few patients with pre-operative symptoms, we noted occasional patients with H. pylori detected after sleeve gastrectomy. We reviewed our experience with our adolescent sleeve gastrectomy cohort to determine the prevalence of H. pylori infection, its predictive factors, and association with outcomes. We hypothesized that H. pylori infection would be associated with pre-operative symptoms, but not surgical outcomes. All patients undergoing sleeve gastrectomy at our hospital were included. We conducted a chart review to determine pre- or post-operative symptoms of gastroesophageal reflux disease GERD or gastritis, operative complications, and long-term anti-reflux therapy after surgery. Pathology reports were reviewed for evidence of gastritis and H. pylori infection. 78 adolescents had laparoscopic sleeve gastrectomy from January 2010 through July 2014. The prevalence of chronic gastritis was 44.9% (35/78) and 11.4% of those patients had H. pylori (4/35). Only one patient with H. pylori had pre-operative symptoms, and only 25.7% (9/35) of patients with pathology-proven gastritis had symptoms. One staple line leak occurred but this patient did not have H. pylori or gastritis. Mean patient follow-up was 10 (3-26) mos. There is a moderate prevalence of gastritis among adolescents undergoing sleeve gastrectomy, but only a small number of these patients had H. pylori infection. Neither the presence of chronic gastritis nor H. pylori infection correlated with symptoms or outcomes. Thus, in the absence of predictive symptomology or adverse outcome in those who are infected, we advocate for continued routine pathologic evaluation without the required need for pre-operative determination unless or until H. pylori infection is associated with adverse surgical outcomes.

To explore the patients' perspective of surgery and early recovery when undergoing lower limb (hip or knee) arthroplasty. Lower limb arthroplasty is a commonly performed procedure for symptomatic arthritis, which has not responded to conservative medical treatment. Each patient's perspective of the surgical process and early recovery period impacts on their quality of life. Open, semistructured qualitative interviews were used to allow for a deeper understanding of the patient perspective when undergoing a hip or knee arthroplasty. Following ethical approval, 30 patients were interviewed between August and November 2016 during the perioperative period while undergoing an elective hip or knee arthroplasty (n = 30). The interviews were performed between the day of surgery and a nine-week postoperative clinic appointment. Data were analysed using an in-depth narrative thematic analysis method. NVivo qualitative data analysis software was used. Seven main themes evolved from the interviews: "improving function and mobility", "pain", "experiences of health care", "support from others", "involvement and understanding of care decisions", "behaviour and coping" and "fatigue and sleeping". The early postoperative recovery period is of vital importance to all surgical patients. This is no different for the orthopaedic patient. However, identifying key self-reported areas of importance from patients can guide clinical focus for healthcare professionals. To have specific patient-reported information regarding key areas of importance during the perioperative phase is invaluable when caring for the orthopaedic surgical patient. It gives insight and understanding in to this increasing population group. This study has also served as a starting point in the development of a questionnaire which could be used to assess interventions in the lower limb arthroplasty population. These results will influence both items and content of the questionnaire. © 2017 John Wiley & Sons Ltd.

Abstract Background: Risk factors for catheter-associated urinary tract infections (CAUTIs) in patients undergoing non-cardiac surgical procedures have been well documented. However, the variables associated with CAUTIs in the cardiac surgical population have not been clearly defined. Therefore, the purpose of this study was to investigate risk factors associated with CAUTIs in patients undergoing cardiac procedures. Methods: All patients undergoing cardiac surgery at a single institution from 2006 through 2012 (4,883 patients) were reviewed. Patients with U.S. Centers for Disease Control (CDC) criteria for CAUTI were identified from the hospital's Quality Assessment database. Pre-operative, operative, and post-operative patient factors were evaluated. Univariate and multivariable analyses were used to identify significant correlations between perioperative characteristics and CAUTIs. Results: There were 55 (1.1%) documented CAUTIs in the study population. On univariate analysis, older age, female gender, diabetes mellitus, cardiogenic shock, urgent or emergent operation, packed red blood cell (PRBC) units transfused, and intensive care unit length of stay (ICU LOS) were all significantly associated with CAUTI [p<0.05]. On multivariable logistic regression, older age, female gender, diabetes mellitus, and ICU LOS remained significantly associated with CAUTI. Additionally, there was a significant association between CAUTI and 30-d mortality on univariate analysis. However, when controlling for common predictors of operative mortality on multivariable analysis, CAUTI was no longer associated with mortality. Conclusions: There are several identifiable risk factors for CAUTI in patients undergoing cardiac procedures. CAUTI is not independently associated with increased mortality, but it does serve as a marker of sicker patients more likely to die from other comorbidities or complications. Therefore, awareness of the high-risk nature of these patients should lead to increased diligence and may help to improve peri-operative outcomes. Recognizing patients at high risk for CAUTI may lead to improved measures to decrease CAUTI rates within this population. PMID:26115336

Outcomes for extracorporeal membrane oxygenation (ECMO) have been described for patients with single ventricle physiology (SVP) undergoing cavopulmonary connection (Glenn procedure). An alternative surgical pathway for patients with SVP consists of an initial hybrid procedure followed by a comprehensive Stage II procedure. No data exist describing the outcomes of patients requiring ECMO after the comprehensive Stage II procedure. The goal of this study is to describe the outcomes for patients who required ECMO after the comprehensive Stage II procedure. Data from the Extracorporeal Life Support Organization (ELSO) registry from 2001 to 2015 for children undergoing the comprehensive Stage II procedure older than 3 months of age were retrospectively analyzed. Demographics and ECMO characteristics were recorded. A total of six children required ECMO support after the comprehensive Stage II procedure (2 males, 4 females). Four patients had the diagnosis of hypoplastic left heart syndrome and two patients had the diagnosis of an unbalanced atrioventricular septal defect. Bypass time was 242.8 ± 110.9 min and cross-clamp time was 91.2 ± 46.2 min for the surgical procedure. Weight was 5.8 ± 1.3 kg and age was 150.2 + 37.9 days at time of ECMO. ECMO duration was 276.0 ± 218.1 h. Complications during the ECMO run included hemorrhage in four patients (67%), renal dysfunction in two patients (33%), and neurologic injury in two patients (33%). Four patients (67%) were discharged alive after ECMO decannulation. Despite being a much more extensive surgical procedure, the morbidity and mortality after ECMO in patients undergoing the comprehensive Stage II procedure are similar to those in patients undergoing the Glenn procedure. If needed, ECMO support is reasonable for patients after the comprehensive Stage II procedure. © 2016 International Center for Artificial Organs and Transplantation and Wiley Periodicals, Inc.

2017-07-01

Certain critically ill patients with advanced acute limb ischemia with a nonviable extremity may be unsuitable for transport to the operating room to undergo definitive amputation. In these unstable patients, rapid regional cryotherapy allows for prompt infectious source control and correction of hemodynamic and metabolic abnormalities, thereby lessening the risk associated with definitive surgical amputation. We describe our refined technique for lower extremity physiologic cryoamputation and review our institutional experience. After adequate analgesia is administered to the patient, a heating pad is secured circumferentially at the proximal amputation margin and the affected extremity is placed in a customized Styrofoam cooler. A circumferential seal is secured at the proximal chill zone without use of a tourniquet and dry ice is placed into the cooler to surround the entire affected leg. Delayed definitive lower extremity amputation is later performed when hemodynamic and metabolic derangements are corrected. We reviewed 5 patients who underwent lower extremity cryoamputation with this technique identified at our institution between 2005 and 2015. Age ranged from 31 to 79 years old. All presented with severe foot infection and septic shock requiring vasopressor support. All 5 patients stabilized hemodynamically following the initial cryoamputation and later underwent definitive lower extremity amputation, with a median time of 3 days following initial cryoamputation. Lower extremity physiologic cryoamputation is an effective, immediate bedside procedure that can provide local source control and the opportunity for correction of metabolic derangements in initially unstable patients to lessen the risk for definitive major lower extremity amputation. Refinement of the cryoamputation technique, as described in this report, allows for a predictable and reproducible physiologic amputation. Copyright © 2017 Elsevier Inc. All rights reserved.

Thoracic-lumbar vertebral fracture is very common in clinic, and late post-traumatic kyphosis is the main cause closely related to the patients' life quality, which has evocated extensive concern for the surgical treatment of the disease. This study aimed to analyze the clinical outcomes and surgical strategies for late post-traumatic kyphosis after failed thoracolumbar fracture operation. All patients presented back pain with kyphotic apex vertebrae between T12 and L3. According to Frankel classification grading system, among them, 3 patients were classified as grade D, with the ability to live independently. A systematic review of 12 case series of post-traumatic kyphosis after failed thoracolumbar fracture operation was involved. Wedge osteotomy was performed as indicated-posterior closing osteotomy correction in 5 patients and anterior open-posterior close correction in 7 patients.Postoperatively, thoracolumbar x-rays were obtained to evaluate the correction of kyphotic deformity, visual analog scales (VAS) and Frankel grading system were used for access the clinical outcomes. All the patients were followed up, with the average period of 38.5 months (range 24-56 months). The Kyphotic Cobb angle was improved from preoperative (28.65 ± 11.41) to postoperative (1.14 ± 2.79), with the correction rate of 96.02%. There was 1 case of intraoperative dural tear, without complications such as death, neurological injury, and wound infection. According to Frankel grading system, no patient suffered deteriorated neurological symptoms after surgery, and 2 patients (2/3) experienced significant relief after surgery. The main VAS score of back pain was improved from preoperative (4.41 ± 1.08) to postoperative (1.5 ± 0.91) at final follow-up, with an improvement rate of 65.89%. Surgical treatment of late post-traumatic kyphosis after failed thoracolumbar fracture operation can obtain good radiologic and clinical outcomes by kyphosis correction, decompression, and posterior stability.

Surgical treatment for spinal tuberculosis includes focal tuberculosis debridement, segmental stability reconstruction, neural decompression and kyphotic deformity correction. For the lesions mainly involved anterior and middle column of the spine, anterior operation of debridement and fusion with internal fixation has been becoming the most frequently used surgical technique for the spinal tuberculosis. However, high risk of structural damage might relate with anterior surgery, such as damage in lungs, heart, kidney, ureter and bowel, and the deformity correction is also limited. Due to the organs are in the front of spine, there are less complications in posterior approach. Spinal pedicle screw passes through the spinal three-column structure, which provides more powerful orthopedic forces compared with the vertebral body screw, and the kyphotic deformity correction effect is better in posterior approach. In this paper, we report a 68-year-old male patient with thoracic tuberculosis who underwent surgical treatment by debridement, interbody fusion and internal fixation via posterior approach only. The patient was placed in prone position under general anesthesia. Posterior midline incision was performed, and the posterior spinal construction was exposed. Then place pedicle screw, and fix one side rod temporarily. Make the side of more bone destruction and larger abscess as lesion debridement side. Resect the unilateral facet joint, and retain contralateral structure integrity. Protect the spinal cord, nerve root. Clear sequestrum, necrotic tissue, abscess of paravertebral and intervertebral space. Specially designed titanium mesh cages or bone blocks were implanted into interbody. Fix both side rods and compress both sides to make the mesh cages and bone blocks tight. Reconstruct posterior column structure with allogeneic bone and autologous bone. Using this technique, the procedures of debridement, spinal cord decompression, deformity correction, bone grafting, and internal fixation can be completed with only one incision and surgical position, and the deformity correction efficiency is higher than anterior surgery. © 2016 Chinese Orthopaedic Association and John Wiley & Sons Australia, Ltd.

Recent reports have suggested that caudal anesthesia may be associated with an increased risk of postoperative surgical complications. We examined our experience with caudal anesthesia in hypospadias repair to evaluate for increased risk of urethrocutaneous fistula or glanular dehiscence. All hypospadias repairs performed by a single surgeon in 2001-2014 were reviewed. Staged or revision surgeries were excluded. Patient age, weight, hypospadias severity, surgery duration, month and year of surgery, caudal anesthesia use, and postoperative complications were recorded. Bivariate and multivariate statistical analyses were performed. We identified 395 single-stage primary hypospadias repairs. Mean age was 15.6 months; 326 patients had distal (83%) and 69 had proximal (17%) hypospadias. Caudal anesthetics were used in 230 (58%) cases; 165 patients (42%) underwent local penile block at the discretion of the surgeon and/or anesthesiologist. Complications of urethrocutaneous fistula or glanular deshiscence occurred in 22 patients (5.6%) and were associated with caudal anesthetic use (OR 16.5, 95% CI 2.2-123.8, P = 0.007), proximal hypospadias (OR 8.2, 95% CI 3.3-20.0, P < 0.001), increased surgical duration (OR 1.01, 95% CI 1.01-1.02, P < 0.001), and earlier year of practice (OR 3.0, 95% CI 1.2-7.9, P = 0.03 for trend). After adjusting for confounding variables via multivariable logistic regression, both caudal anesthetic use (OR 13.4, 95% CI 1.8-101.8, P = 0.01) and proximal hypospadias (OR 6.8, 95% CI 2.7-16.9, P < 0.001) remained highly associated with postoperative complications. In our experience, caudal anesthesia was associated with an over 13-fold increase in the odds of developing postoperative surgical complications in boys undergoing hypospadias repair even after adjusting for urethral meatus location. Until further investigation occurs, clinicians should carefully consider the use of caudal anesthesia for children undergoing hypospadias repair. © 2017 John Wiley & Sons Ltd.

To assess incremental charges of patients experiencing venous thromboembolisms (VTE) across various types of elective inpatient surgical procedures with administration of general anesthesia in the US. The authors performed a retrospective study utilizing data from a nationwide hospital operational records database from July 2014 through June 2015 to compare a group of inpatients experiencing a VTE event post-operatively to a propensity score matched group of inpatients who did not experience a VTE. Patients included in the analysis had a hospital admission for an elective inpatient surgical procedure with the use of general anesthesia. Procedures of the heart, brain, lungs, and obstetrical procedures were excluded, as these procedures often require a scheduled ICU stay post-operatively. Outcomes examined included VTE events during hospitalization, length of stay, unscheduled ICU transfers, number of days spent in the ICU if transferred, 3- and 30-day re-admissions, and total hospital charges incurred. The study included 17,727 patients undergoing elective inpatient surgical procedures. Of these, 36 patients who experienced a VTE event were matched to 108 patients who did not. VTE events occurred in 0.2% of the study population, with most events occurring for patients undergoing total knee replacement. VTE patients had a mean total hospital charge of $60,814 vs $48,325 for non-VTE patients, resulting in a mean incremental charge of $11,979 (p < .05). Compared to non-VTE patients, VTE patients had longer length of stay (5.9 days vs 3.7 days, p < .001), experienced a higher rate of 3-day re-admissions (3 vs 0 patients) and 30-day re-admissions (7 vs 2 patients). Patients undergoing elective inpatient surgical procedures with general anesthesia who had a VTE event during their primary hospitalization had a significantly longer length of stay and significantly higher total hospital charges than comparable patients without a VTE event.

To assess how obesity or diabetes mellitus impacts outcomes in patients undergoing cardiac surgery in pediatric hospitals. A multi-institutional, matched case-control study of the Pediatric Health Information System database was performed. Tertiary children's hospitals in the United States. All cardiac surgical cases in patients with obesity or diabetes mellitus between 2004 and 2012 were included. Cases were matched to controls by age, sex, race, and Risk Adjustment for Congenital Heart Surgery score. Mortality, surgical complications, and hospital utilization. Differences in outcome measures were assessed by chi-square and Mann-Whitney tests. P value < .05 was significant. Six hundred twenty-nine cardiac surgical cases (median age 17 years [IQR 12-32]) with obesity or diabetes mellitus were matched to 629 controls. Cases demonstrated lower median household income than those in the control group ($38,031 [IQR $31,900-$48,844] vs. ($41,896 [IQR $32,854-$56,020], P < .001). Mortality was similar between cases and controls (22% vs. 1.9%, P =.692). Surgical complications occurred similarly between cases and controls (13.5% vs. 12.4%, P = .535). Cases had longer intensive care unit length of stay than controls (3 vs. 2 days, P = .001), resulting in longer overall hospital length of stay (5 vs. 4 days, P < .001). Cases also had a higher odds of undergoing mechanical ventilation for >96 hours (OR 2.0, 95% CI 1.1-3.7) and higher rate of total parenteral nutrition use (7.2% vs. 4.5%, P = .040). Median hospital charges were higher in cases (clinical: $6,696 vs. $5,872; laboratory: $14,168 vs. $12,251; pharmacy: $12,971 vs. $10,426; imaging: $6,259 vs. $5,660; P ≤ .030 for all). The presence of obesity or diabetes mellitus was associated with increased postoperative morbidity, hospital utilization, and cost in patients undergoing cardiac surgery in pediatric hospitals. © 2016 Wiley Periodicals, Inc.

Operative hysteroscopy versus vacuum aspiration for incomplete spontaneous abortion (HY-PER): study protocol for a randomized controlled trial.

Incomplete spontaneous abortions are defined by the intrauterine retention of the products of conception after their incomplete or partial expulsion. This condition may be managed by expectant care, medical treatment or surgery. Vacuum aspiration is currently the standard surgical treatment in most centers. However, operative hysteroscopy has the advantage over vacuum aspiration of allowing the direct visualization of the retained conception product, facilitating its elective removal while limiting surgical complications. Inadequately powered retrospective studies reported subsequent fertility to be higher in patients treated by operative hysteroscopy than in those treated by vacuum aspiration. These data require confirmation in a randomized controlled trial comparing fertility rates between women undergoing hysteroscopy and those undergoing vacuum aspiration for incomplete spontaneous abortion. After providing written informed consent, 572 women with incomplete spontaneous abortion recruited from 15 centers across France will undergo randomization by a centralized computer system for treatment by either vacuum aspiration or operative hysteroscopy. Patients will not be informed of the type of treatment that they receive and will be cared for during their hospital stay in accordance with standard practices at each center. The patients will be monitored for pregnancy or adverse effects by a telephone conversation or questionnaire sent by e-mail or post over a period of two years. In cases of complications, failure of the intervention or diagnosis of uterine cavity disease, patient care will be left to the discretion of the medical center team. If our hypothesis is confirmed, this study will provide evidence that the use of operative hysteroscopy can increase the number of pregnancies continuing beyond 22 weeks of gestation in the two-year period following incomplete spontaneous abortion without increasing the incidence of morbidity and peri- and postoperative complications. The standard surgical treatment of this condition would thus be modified. This study would therefore have a large effect on the surgical management of incomplete spontaneous abortion.

Lumbar disc herniation (LDH) surgery is usually recommended when conservative treatments fail to manage patients' symptoms. However, many patients undergoing LDH surgery continue to report pain and disability. Preoperative psychological factors have shown to be predictive for postoperative outcomes. Our aim was to systematically review studies that prospectively examined the prognostic value of factors in the Fear Avoidance Model (FAM), including back pain, leg pain, catastrophizing, anxiety, fear-avoidance, depression, physical activity and disability, to predict postoperative outcomes in patients undergoing LDH surgery. We performed a systematic literature review of prospective studies that measured any FAM factors preoperatively to predict postoperative outcomes for patients undergoing LDH surgery. Our search databases included PubMed, CINAHL, and PsycINFO. We assessed the quality of each included study using a certain quality assessment list. Degree of agreement between reviewers on quality assessment was examined. Results related to FAM factors in the included studies were summarized. Thirteen prospective studies met our inclusion criteria. Most studies were considered high quality. Heterogeneity was present between the included studies in many aspects. The most common FAM factors examinered were baseline pain, disability and depression. In, general, depression, fear-avoidance behaviors, passive pain coping, and anxiety FAM factors appeared to have negative influence on LDH surgical outcome. Baseline back pain and leg pain appeared to have differing prognostic value on LDH surgical outcomes. FAM factors seem to influence LDH surgical outcomes. Patients with high levels of depression, anxiety and fear-avoidance behaviors are more likely to have poor outcomes following LDH surgery. Conversely, high levels of leg pain, but not back pain seem to be predictor for favorable LDH surgery outcome. More research is needed to determine the exact role of FAM factors on LDH surgical outcome and the value for screening for these factors.

Glucocorticoid injection (GCI) and surgical rotator cuff repair are two widely used treatments for rotator cuff tendinopathy. Little is known about the way in which medical and surgical treatments affect the human rotator cuff tendon in vivo. We assessed the histological and immunohistochemical effects of these common treatments on the rotator cuff tendon. Controlled laboratory study. Supraspinatus tendon biopsies were taken before and after treatment from 12 patients undergoing GCI and 8 patients undergoing surgical rotator cuff repair. All patients were symptomatic and none of the patients undergoing local GCI had full thickness tears of the rotator cuff. The tendon tissue was then analysed using histological techniques and immunohistochemistry. There was a significant increase in nuclei count and vascularity after rotator cuff repair and not after GCI (both p=0.008). Hypoxia inducible factor 1α (HIF-1α) and cell proliferation were only increased after rotator cuff repair (both p=0.03) and not GCI. The ionotropic N-methyl-d-aspartate receptor 1 (NMDAR1) glutamate receptor was only increased after GCI and not rotator cuff repair (p=0.016). An increase in glutamate was seen in both groups following treatment (both p=0.04), while an increase in the receptor metabotropic glutamate receptor 7 (mGluR7) was only seen after rotator cuff repair (p=0.016). The increases in cell proliferation, vascularity and HIF-1α after surgical rotator cuff repair appear consistent with a proliferative healing response, and these features are not seen after GCI. The increase in the glutamate receptor NMDAR1 after GCI raises concerns about the potential excitotoxic tendon damage that may result from this common treatment.

OBJECTIVE The goal of this analysis was to define temporal and geographic trends in the surgical treatment of Chiari malformation Type I (CM-I) in a large, privately insured health care network. METHODS The authors examined de-identified insurance claims data from a large, privately insured health care network of over 58 million beneficiaries throughout the United States for the period between 2001 and 2014 for all patients undergoing surgical treatment of CM-I. Using a combination of International Classification of Diseases (ICD) diagnosis codes and Current Procedural Terminology (CPT) codes, the authors identified CM-I and associated diagnoses and procedures over a 14-year period, highlighting temporal and geographic trends in the performance of CM-I decompression (CMD) surgery as well as commonly associated procedures. RESULTS There were 2434 surgical procedures performed for CMD among the beneficiaries during the 14-year interval; 34% were performed in patients younger than 20 years of age. The rate of CMD increased 51% from the first half to the second half of the study period among younger patients (p < 0.001) and increased 28% among adult patients between 20 and 65 years of age (p < 0.001). A large sex difference was noted among adult patients; 78% of adult patients undergoing CMD were female compared with only 53% of the children. Pediatric patients undergoing CMD were more likely to be white with a higher household net worth. Regional variability was identified among rates of CMD as well. The average annual rate of surgery ranged from 0.8 surgeries per 100,000 insured person-years in the Pacific census division to 2.0 surgeries per 100,000 insured person-years in the East South Central census division. CONCLUSIONS Analysis of a large nationwide health care network showed recently increasing rates of CMD in children and adults over the past 14 years.

Sarcopenia, severe skeletal muscle loss, has been identified as a prognostic factor in various malignancies. This study aims to investigate whether sarcopenia is associated with overall survival (OS) and surgical complications in patients with advanced ovarian cancer undergoing primary debulking surgery (PDS). Ovarian cancer patients (n = 216) treated with PDS were enrolled retrospectively. Total skeletal muscle surface area was measured on axial computed tomography at the level of the third lumbar vertebra. Optimum stratification was used to find the optimal skeletal muscle index cut-off to define sarcopenia (≤38.73 cm 2 /m 2 ). Cox-regression and Kaplan-Meier analysis were used to analyse the relationship between sarcopenia and OS. The effect of sarcopenia on the development of major surgical complications was studied with logistic regression. Kaplan-Meier analysis showed a significant survival disadvantage for patients with sarcopenia compared to patients without sarcopenia (p = 0.010). Sarcopenia univariably predicted OS (HR 1.536 (95% CI 1.105-2.134), p = 0.011) but was not significant in multivariable Cox-regression analysis (HR 1.362 (95% CI 0.968-1.916), p = 0.076). Significant predictors for OS in multivariable Cox-regression analysis were complete PDS, treatment in a specialised centre and the development of major complications. Sarcopenia was not predictive of major complications. Sarcopenia was not predictive of OS or major complications in ovarian cancer patients undergoing primary debulking surgery. However a strong trend towards a survival disadvantage for patients with sarcopenia was seen. Future prospective studies should focus on interventions to prevent or reverse sarcopenia and possibly increase ovarian cancer survival. Complete cytoreduction remains the strongest predictor of ovarian cancer survival.

This case report describes the surgical-orthodontic treatment of a 26-year-old post-pubertal male patient with a Class III dentofacial deformity. In the pre-surgical orthodontic phase of treatment, a reverse overjet of 5.5 mm was created and arch compatibility was obtained. A mandibualr set back with BSSO was performed during surgery to restore ideal overjet, overbite, occlusion and optimal esthetics. After 1 year of treatment, the results remained stable.

Patients with idiopathic scoliosis, although otherwise healthy, often have significant concerns about their self-image and appearance. In a group of juveniles and adolescents, this can impact adjustment in school, functioning in peer groups, and general sense of well-being. There are limited data to help physicians reliably and precisely identify those who are at higher risk of poor emotional adjustment even after spine deformity correction. The purpose of this study was to determine the predictors of emotional maladjustment in juvenile and adolescent patients after surgical correction of idiopathic scoliosis. A total of 233 juveniles, mean age 11.26 ± 1.02 (range, 8 to 12) years and 909 adolescents, mean age 14.91 ± 1.61 (range, 13 to 21) years, who underwent surgical correction for idiopathic scoliosis and who were participating in a prospective longitudinal multicenter database, were enrolled in the study. Participants completed the Scoliosis Research Society-22 (SRS-22) questionnaire before surgery and 2 years postoperatively. Radiographs were used to measure Cobb angle and surface measurements were used to determine decompensation and trunk shift. Adolescents reported poorer mental health preoperatively (P<0.05) and 2 years postoperatively (P<0.001) than juveniles; however, both groups reported improved mental health (P<0.001) and self-image (P<0.01) postoperatively. Mental health 2 years postoperatively was predicted by preoperative self-image (P<0.05), mental health (P<0.001), and main thoracic Cobb angle (P<0.05) in the juvenile group. Within the adolescent group, mental health 2 years postoperatively was predicted by preoperative mental health (P<0.001); self-image 2 years postoperatively was predicted by preoperative mental health (P<0.01) and self-image (P<0.001). Self-image and mental health are significantly improved after spine deformity correction in juveniles and adolescents with idiopathic scoliosis. However, consistent with normative development, adolescents are at higher risk for emotional maladjustment than juveniles. Surgical decision making in scoliosis correction should take the emotional status of the patient into consideration.

Obstructive Sleep Apnea and Surgery: Quality Improvement Imperatives and Opportunities

2014-01-01

Obstructive sleep apnea (OSA) is more common in surgical candidates than in the general population and may increase susceptibility to perioperative complications that range from transient desaturation to catastrophic injuries. Understanding the potential impact of OSA on patients’ surgical risk profile is of particular interest to otolaryngologists, who routinely perform airway procedures—including surgical procedures for treatment of OSA. Whereas the effects of OSA on long-term health outcomes are well documented, the relationship between OSA and surgical risk is not collinear, and clear consensus on the nature of the association is lacking. Better guidelines for optimization of pain control, perioperative monitoring, and surgical decision making are potential areas for quality improvement efforts. Many interventions have been suggested to mitigate the risk of adverse events in surgical patients with OSA, but wide variations in clinical practice remain. We review the current literature, emphasizing recent progress in understanding the complex pathophysiologic interactions noted in OSA patients undergoing surgery and outlining potential strategies to decrease perioperative risks.

Surgical site infections are the most common complication of surgery in the United States. Of surgeries in women of reproductive age, hysterectomy is one of the most frequently performed, second only to cesarean birth. Therefore, prevention of surgical site infections in women undergoing gynecologic surgery is an ideal topic for a patient safety bundle. The primary purpose of this safety bundle is to provide recommendations that can be implemented into any surgical environment in an effort to reduce the incidence of surgical site infection. This bundle was developed by a multidisciplinary team convened by the Council on Patient Safety in Women's Health Care. The bundle is organized into four domains: Readiness, Recognition and Prevention, Response, and Reporting and Systems Learning. In addition to recommendations for practice, each of the domains stresses communication and teamwork between all members of the surgical team. Although the bundle components are designed to be adaptable to work in a variety of clinical settings, standardization within institutions is encouraged.

In this study, we examined differences in inpatient costs, length of stay, and in-hospital mortality between hospitalizations for patients with and without sickle cell disease (SCD) undergoing high-volume surgical procedures. We used Clinical Classification Software (CCS) codes to identify discharges in the 2002–2005 Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project for patients who had undergone either cholecystectomy or hip replacement. We limited the non-SCD cohort to hospitals where patients with SCD had undergone the same procedure. We compared inpatient outcomes using summary statistics and generalized linear regression analysis to adjust for patient, hospital, and procedural characteristics. Overall, the median age of surgical patients with SCD was more than 3 decades less than the median age of patients without SCD undergoing the same procedure. In recognition of the age disparity, we limited the analyses to patients aged 18 to 64 years. Nonetheless, patients with SCD undergoing cholecystectomy or hip replacement were 12.1 and 14.4 years younger, had inpatient stays that were 73% and 82% longer, and incurred costs that were 46% and 40% higher per discharge than patients without SCD, respectively. Inpatient mortality for these procedures was low, approximately 0.6% for cholecystectomy and 0.2% for hip replacement, and did not differ significantly between patients with and without SCD. Multivariable regression analyses revealed that higher inpatient costs among patients with SCD were primarily attributable to longer hospital stays. Patients with SCD who underwent cholecystectomy or hip replacement required more health care resources than patients without SCD. PMID:19787790

Chiari malformation type 1 (CM-1) is a variation of hindbrain development that can sometimes occur in asymptomatic individuals. Conventional treatment is surgical decompression, but little is known about the natural history of patients who do not undergo surgical management. This information is critical to determine how these patients should be managed. We conducted a systematic literature review to determine the natural history of CM-1, particularly in patients who did not undergo surgery and in asymptomatic individuals, to help patients and physicians determine when surgery is likely to be beneficial. The literature search was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using the electronic databases PubMed, Scopus, Cochrane Library, and Web of Science. Inclusion and exclusion criteria were predefined. In symptomatic patients who did not undergo surgery, headaches and nausea often improved, whereas ataxia and sensory disturbance tended not to improve spontaneously. Of patients, 27%-47% had an improvement in symptoms after 15 months, and 37%-40% with cough headache and 89% with nausea who were managed nonoperatively improved at follow-up. Most asymptomatic individuals with CM-1 remained asymptomatic (93.3%) even in the presence of syringomyelia. The natural history of mild symptomatic and asymptomatic CM-1 in adults is relatively benign and nonprogressive; the decision to perform surgical decompression should be based on severity and duration of a patient's symptoms at presentation. It is reasonable to observe a patient with mild or asymptomatic symptoms even in the presence of significant tonsillar descent or syringomyelia. Copyright © 2017 Elsevier Inc. All rights reserved.

Diagnostic and therapeutic management of hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is an increasing health problem, representing the second cause of cancer-related mortality worldwide. The major risk factor for HCC is cirrhosis. In developing countries, viral hepatitis represent the major risk factor, whereas in developed countries, the epidemic of obesity, diabetes and nonalcoholic steatohepatitis contribute to the observed increase in HCC incidence. Cirrhotic patients are recommended to undergo HCC surveillance by abdominal ultrasounds at 6-mo intervals. The current diagnostic algorithms for HCC rely on typical radiological hallmarks in dynamic contrast-enhanced imaging, while the use of α-fetoprotein as an independent tool for HCC surveillance is not recommended by current guidelines due to its low sensitivity and specificity. Early diagnosis is crucial for curative treatments. Surgical resection, radiofrequency ablation and liver transplantation are considered the cornerstones of curative therapy, while for patients with more advanced HCC recommended options include sorafenib and trans-arterial chemo-embolization. A multidisciplinary team, consisting of hepatologists, surgeons, radiologists, oncologists and pathologists, is fundamental for a correct management. In this paper, we review the diagnostic and therapeutic management of HCC, with a focus on the most recent evidences and recommendations from guidelines. PMID:26576088
