Cytoreductive surgery plus hypertermic intraperitoneal chemotherapy has emerged as a major comprehensive treatment of peritoneal malignancies and is currently the standard of care for appendiceal epithelial neoplasms and pseudomyxoma peritonei syndrome as well as malignant peritoneal mesothelioma. Unfortunately, there are some worldwide variations of the cytoreductive surgery and hypertermic intraperitoneal chemotherapy techniques since no single technique has so far demonstrated its superiority over the others. Therefore, standardization of practices might enhance better comparisons between outcomes. In these settings, the Brazilian Society of Surgical Oncology considered it important to present a proposal for standardizing cytoreductive surgery plus hypertermic intraperitoneal chemotherapy procedures in Brazil, with a special focus on producing homogeneous data for the developing Brazilian register for peritoneal surface malignancies.

To evaluate the cost-effectiveness of a diagnostic laparoscopy prior to primary cytoreductive surgery to prevent futile primary cytoreductive surgery (i.e. leaving >1cm residual disease) in patients suspected of advanced stage ovarian cancer. An economic analysis was conducted alongside a randomized controlled trial in which patients suspected of advanced stage ovarian cancer who qualified for primary cytoreductive surgery were randomized to either laparoscopy or primary cytoreductive surgery. Direct medical costs from a health care perspective over a 6-month time horizon were analyzed. Health outcomes were expressed in quality-adjusted life-years (QALYs) and utility was based on patient's response to the EQ-5D questionnaires. We primarily focused on direct medical costs based on Dutch standard prices. We studied 201 patients, of whom 102 were randomized to laparoscopy and 99 to primary cytoreductive surgery. No significant difference in QALYs (utility=0.01; 95% CI 0.006 to 0.02) was observed. Laparoscopy reduced the number of futile laparotomies from 39% to 10%, while its costs were € 1400 per intervention, making the overall costs of both strategies comparable (difference € -80 per patient (95% CI -470 to 300)). Findings were consistent across various sensitivity analyses. In patients with suspected advanced stage ovarian cancer, a diagnostic laparoscopy reduced the number of futile laparotomies, without increasing total direct medical health care costs, or adversely affecting complications or quality of life.

Treatment in advanced stage epithelial ovarian cancer (EOC) is based on primary cytoreductive surgery followed by platinum-based chemotherapy. Successful cytoreduction to minimal residual tumour burden is the most important determinant of prognosis. However, extensive surgical procedures to achieve maximal debulking are inevitably associated with postoperative morbidity and mortality. The objective of this study is to determine predictors of 30-day morbidity after primary cytoreductive surgery for advanced stage EOC. All patients in the South Western part of the Netherlands who underwent primary cytoreductive surgery for advanced stage EOC between January 2004 and December 2007 were identified from the Rotterdam Cancer Registry database. All peri- and postoperative complications within 30 days after surgery were registered and classified according to the definitions of the National Surgical Quality Improvement Programme (NSQIP). To investigate independent predictors of 30-day morbidity, a Cox proportional hazards model with backward stepwise elimination was utilised. The identified predictors were entered into a nomogram. Two hundred and ninety-three patients entered the study protocol. Optimal cytoreduction was achieved in 136 (46%) patients. 30-day morbidity was seen in 99 (34%) patients. Postoperative morbidity could be predicted by age (P=0.007; odds ratio [OR] 1.034), WHO performance status (P=0.046; OR 1.757), extent of surgery (P=0.1308; OR=2.101), and operative time (P=0.017; OR 1.007) with an optimism corrected c-statistic of 0.68. 30-day morbidity could be predicted by age, WHO performance status, operative time and extent of surgery. The generated nomogram could be valuable for predicting operative risk in the individual patient.

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

Maximal cytoreduction to minimal residual tumor is the most important determinant of prognosis in patients with advanced stage epithelial ovarian cancer (EOC). Preoperative prediction of suboptimal cytoreduction, defined as residual tumor >1 cm, could guide treatment decisions and improve counseling. The objective of this study was to identify predictive computed tomographic (CT) scan and clinical parameters for suboptimal cytoreduction at primary cytoreductive surgery for advanced stage EOC and to generate a nomogram with the identified parameters, which would be easy to use in daily clinical practice. Between October 2005 and December 2008, all patients with primary surgery for suspected advanced stage EOC at six participating teaching hospitals in the South Western part of the Netherlands entered the study protocol. To investigate independent predictors of suboptimal cytoreduction, a Cox proportional hazard model with backward stepwise elimination was utilized. One hundred and fifteen patients with FIGO stage III/IV EOC entered the study protocol. Optimal cytoreduction was achieved in 52 (45%) patients. A suboptimal cytoreduction was predicted by preoperative blood platelet count (p=0.1990; odds ratio (OR)=1.002), diffuse peritoneal thickening (DPT) (p=0.0074; OR=3.021), and presence of ascites on at least two thirds of CT scan slices (p=0.0385; OR=2.294) with a for-optimism corrected c-statistic of 0.67. Suboptimal cytoreduction was predicted by preoperative platelet count, DPT and presence of ascites. The generated nomogram can, after external validation, be used to estimate surgical outcome and to identify those patients, who might benefit from alternative treatment approaches.

Extensive surgical procedures to achieve maximal cytoreduction in patients with advanced stage epithelial ovarian cancer (EOC) are inevitably associated with postoperative morbidity and mortality. This study aimed to identify preoperative predictors of 30-day morbidity after primary cytoreductive surgery for advanced stage EOC and to develop a nomogram for individual risk assessment. Patients in The Netherlands who underwent primary cytoreductive surgery for advanced stage EOC between January 2004 and December 2007. All peri- and postoperative complications within 30 days after surgery were registered and classified. To investigate predictors of 30-day morbidity, a Cox proportional hazard model with backward stepwise elimination was utilized. The identified predictors were entered into a nomogram. The main outcome was to identify parameters that predict operative risk. 293 patients entered the study protocol. Optimal cytoreduction was achieved in 136 (46%) patients. Thirty-day morbidity was seen in 99 (34%) patients. Morbidity could be predicted by age (p = 0.033; OR 1.024), preoperative hemoglobin (p = 0.194; OR 0.843), and WHO performance status (p = 0.015; OR 1.821) with a optimism-corrected c-statistic of 0.62. Determinants co-morbidity status, serum CA125 level, platelet count, and presence of ascites were comparable in both groups. Thirty-day morbidity after primary cytoreductive surgery for advanced stage EOC could be predicted by age, hemoglobin, and WHO performance status. The generated nomogram could be valuable for predicting operative risk in the individual patient.

A review of 92 patients with Stage III nonseminomatous tumors treated at Roswell Park Memorial Institute between 1970-1979 was undertaken to verify changes in concepts as related to multiple agent chemotherapy and cytoreductive surgery. Each patient had a minimal follow-up of 18 months. Fifty-three patients were seen before 1975. Eighteen had metastasis to the lungs only. These were treated with a variety of single chemotherapeutic agents and cytoreductive surgery. The survival of this group was 38%. Among 35 patients with lung and visceral involvement seen at the same time, only one patient is alive. Thirty-nine patients were seen after 1975 and treated with multi-drug chemotherapy and cytoreductive surgery. The current survival rate of 23 patients with lung metastasis only is 69%. Among 16 patients with lung and visceral involvement, the present survival rate is 31%. This report confirms the effectiveness of multi-drug therapy in conjunction with cytoreductive surgery in the treatment of disseminated testicular tumors.

Surgery for advanced epithelial ovarian cancer.

Cytoreductive surgery for patients with advanced epithelial ovarian cancer has been practised since the pioneering work of Tom Griffiths in 1975. Further research has demonstrated the prognostic significance of the extent of metastatic disease pre-operatively, and of complete cytoreduction post-operatively. Patients with advanced epithelial ovarian cancer should be referred to high volume cancer units, and managed by multidisciplinary teams. The role of thoracoscopy and resection of intrathoracic disease is presently investigational. In recent years, there has been increasing use of neoadjuvant chemotherapy and interval cytoreductive surgery in patients with poor performance status, which is usually due to large volume ascites and/or large pleural effusions. Neoadjuvant chemotherapy reduces the post-operative morbidity, but if the tumour responds well to the chemotherapy, the inflammatory response makes the surgery more difficult. Post-operative morbidity is generally tolerable, but increases in older patients, and in those having multiple, aggressive surgical procedures, such as bowel resection or diaphragmatic stripping. Primary cytoreductive surgery should be regarded as the gold standard for most patients until a test is developed which would allow the prediction of platinum resistance pre-operatively.

To assess the impact of 5 or more cycles of neoadjuvant chemotherapy (NACT) and cytoreductive outcomes on overall survival (OS) in patients undergoing interval debulking surgery (IDS) for advanced ovarian cancer. A retrospective review of patients receiving NACT followed by IDS between 2007 and 2017. Patients were analysed according to number of NACT cycles received: group 1 consisted of patients receiving ≤4 cycles and group 2 consisted of those receiving ≥5 cycles. Outcomes were stratified by cytoreductive outcome, surgical complexity, stage and chemotherapy exposure. 231 patients in group 1 and 167 in group 2 were identified. In group 1, the OS for those achieving Complete (R0), Optimal<1 cm (R1) and Suboptimal (R2) was 51.1, 36.1, and 34.3 months respectively. Statistically significant differences in survival were seen in patients achieving R0vR2 (p < 0.019) but not in R0vR1 (p = 0.125) or R1vR2 (p = 0.358). In group 2, the OS for those achieving R0, R1 and R2 was 53.0, 24.7, and 22.1 months respectively. Statistically significant differences were seen between R0vR1 and R0vR2 (p < 0.00001) but not between R1vR2 (p = 0.917). No difference in OS was seen between groups 1 and 2. In patients achieving R1, there was a trend towards decreasing OS with increasing exposure to NACT from 36.1 (95%CI 32.0-40.2)months with 3 cycles to 24.3 (95%CI 14.4-34.2)months with ≥6 cycles. Surgery with utilisation of cytoreductive procedures to achieve complete clearance should be offered to all patients even after ≥5 cycles if R0 can be achieved. R1 cytoreduction has questionable value in those receiving ≤4 cycles and no value in those receiving ≥5 cycles.

Peritoneal surface malignancy (PSM) is a frequent occurrence in the natural history of colorectal cancer (CRC). Although significant advances have been made in screening of CRC, similar progress has yet to be made in the early detection of PSM of colorectal cancer origin. The fact that advanced CRC can be confined to the peritoneal surface without distant dissemination forms the basis for aggressive multi-modality therapy consisting of cytoreductive surgery (CRS) plus hyperthermic intra-peritoneal chemotherapy (HIPEC), and neoadjuvant and/or adjuvant systemic therapy. Reported overall survival with complete CRS+HIPEC exceeds that of systemic therapy alone for the treatment of PSM from CRC, underscoring the advantage of this multi-modality therapeutic approach. Patients with limited peritoneal disease from CRC can undergo complete cytoreduction, which is associated with the best reported outcomes. As early or limited peritoneal carcinomatosis is undetectable by conventional imaging modalities, second look laparotomy is an important means to identify disease in high-risk patients at a stage most amenable to complete cytoreduction. This review focuses on the identification of patients at risk for PSM from CRC and discusses the role of second look laparotomy. PMID:23459716

Purpose: To identify the prognostic role of adjuvant abdominal radiation therapy (RT) on oncologic outcomes as a part of multimodal treatment in the management of desmoplastic small round cell tumor (DSRCT) and to determine its impact according to the quality of surgical resection. Methods and Materials: All patients treated for primary abdominal DSRCT in 8 French centers from 1991 to 2014 were included. Patients were retrospectively staged into 3 groups: group A treated with adjuvant RT after cytoreductive surgery, group B without RT after cytoreductive surgery, and group C by exclusive chemotherapy. Peritoneal progression-free survival (PPFS), progression-free survival (PFS), andmore » overall survival (OS) were evaluated. We also performed a direct comparison between groups A and B to evaluate RT after cytoreductive surgery. Radiation therapy was also evaluated according to completeness of surgery: complete cytoreductive surgery (CCS) or incomplete cytoreductive surgery (ICS). Results: Thirty-seven (35.9%), thirty-six (34.9%), and thirty (28.0%) patients were included in groups A, B, and C, respectively. Three-year OS was 61.2% (range, 41.0%-76.0%), 37.6% (22.0%-53.1%), and 17.3% (6.3%-32.8%) for groups A, B, and C, respectively. Overall survival, PPFS, and PFS differed significantly among the 3 groups (P<.001, P<.001, and P<.001, respectively). Overall survival and PPFS were higher in group A (RT group) compared with group B (no RT group) (P=.045 and P=.006, respectively). Three-year PPFS was 23.8% (10.3%-40.4%) for group A and 12.51% (4.0%-26.2%) for group B. After CCS, RT improved PPFS (P=.024), but differences in OS and PFS were not significant (P=.40 and P=.30, respectively). After ICS, RT improved OS (P=.044). A trend of PPFS and PFS increase was observed, but the difference was not statistically significant (P=.073 and P=.076). Conclusions: Adjuvant RT as part of multimodal treatment seems to confer oncologic benefits for patients treated for abdominal DSRCT after cytoreductive surgery and perioperative chemotherapy.« less

To construct a tool, using computed tomography (CT) imaging and preoperative clinical variables, to estimate successful primary cytoreduction for advanced epithelial ovarian cancer (EOC). Women who underwent primary cytoreductive surgery for stage IIIC/IV EOC at Mayo Clinic between 1/2/2003 and 12/30/2011 and had preoperative CT images of the abdomen and pelvis within 90days prior to their surgery available for review were included. CT images were reviewed for large-volume ascites, diffuse peritoneal thickening (DPT), omental cake, lymphadenopathy (LP), and spleen or liver involvement. Preoperative factors included age, body mass index (BMI), Eastern Cooperative Oncology Group performance status (ECOG PS), American Society of Anesthesiologists (ASA) score, albumin, CA-125, and thrombocytosis. Two prediction models were developed to estimate the probability of (i) complete and (ii) suboptimal cytoreduction (residual disease (RD) >1cm) using multivariable logistic analysis with backward and stepwise variable selection methods. Internal validation was assessed using bootstrap resampling to derive an optimism-corrected estimate of the c-index. 279 patients met inclusion criteria: 143 had complete cytoreduction, 26 had suboptimal cytoreduction (RD>1cm), and 110 had measurable RD ≤1cm. On multivariable analysis, age, absence of ascites, omental cake, and DPT on CT imaging independently predicted complete cytoreduction (c-index=0.748). Conversely, predictors of suboptimal cytoreduction were ECOG PS, DPT, and LP on preoperative CT imaging (c-index=0.685). The generated models serve as preoperative evaluation tools that may improve counseling and selection for primary surgery, but need to be externally validated. Copyright © 2015 Elsevier Inc.

Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is an effective treatment for peritoneal carcinomatosis (PC) from multiple origins, however is associated with increased complications compared to conventional gastrointestinal surgery. The aetiology of enterocutaneous fistulas (ECF) in most cases is a result of various contributing factors and therefore remains a major clinical problem, occurring in 4-34% of patients post-CRS. The aim of this study was to analyze the incidence and outcome of ECF following CRS/HIPEC. From April 1999 to September 2015, 53 patients of 918 CRS/HIPEC procedures developed an ECF. Patient, operative and postoperative data were retrospectively analyzed to determine aetiology, classification outcome and possible contributing factors were reviewed on univariate and multivariate analysis. We report a 5.8% ECF rate, diagnosed at a median of 13 days. The mortality rate was 5.7% and other morbidity was significantly increased (p = 0.0001). Twenty-five (47.2%), 8 (15.1%) and 20 patients (37.7%) had low, moderate and high output ECF respectively. Patients that had a CC2 cytoreduction, abdominal VAC or smoked had a higher risk of fistula (p = 0.004, p < 0.0001, p = 0.008). Spontaneous closure was achieved in 49.2% with conservative treatment (median 29 days) and 33.9% underwent surgical intervention. Preoperative serum albumin <35 g/L (p = 0.04), PCI>17 (p = 0.025) and operation >8.6 h s (p = 0.001) were independent risk factors on multivariate analysis. Overall and 5-year survival was significantly reduced (p < 0.0001,p = 0.016). CRS/HIPEC remains an effective treatment modality for PC in selected patients with a comparable ECF incidence to reported elective gastrointestinal surgery rates. This study identifies multiple risk factors that should be considered in patients undergoing CRS/HIPEC. Copyright © 2016 Elsevier Ltd. All rights reserved.

Serum tumor markers are prognostic in patients with colorectal cancer peritoneal carcinomatosis (CRPC) undergoing cytoreductive surgery (CRS) and intraperitoneal chemotherapy (IPC). Assessment of the ratio of tumor marker to volume, as depicted by peritoneal carcinomatosis index (PCI), and how this may affect overall (OS) and recurrence free survival (RFS) has not been reported. Survival effect of this ratio was analyzed in patients with CRPC managed from 1996 to 2016 with CRS and IPC. Of 260 patients included, those with low CEA/PCI ratio (<2.3) had longer median OS (56 vs 24 months, P = 0.001) and RFS (13 vs 9 months, P = 0.02). The prognostic impact of CEA/PCI ratio was most pronounced in patients with PCI ≤ 10 (OS of 72 vs 30 months, P < 0.001; RFS of 21 vs 10 months, P = 0.002). In multivariable analysis, elevated CEA/PCI ratio was independently associated with poorer OS (adjusted HR 1.85, 95%CI 1.11-3.10, P = 0.02) and RFS (adjusted HR 1.58, 95%CI 1.04-2.41, P = 0.03). CEA/PCI ratio is an independent prognostic factor for OS and RFS in CRPC. This novel approach allows both tumor activity and volume to be accounted for in one index, thus potentially providing a more accurate indication of tumor biological behavior. © 2017 Wiley Periodicals, Inc.

Features of ultrasound picture of morphologically verified recurrence of ovarian cancer in 21 patients are presented, who received combined treatment including cytoreductive surgery in the form of hysterectomy with oophorectomy, resection of the greater omentum and 6 courses of chemotherapy CAP for ovarian cancer stage III (FIGO). In all patients cytoreductive surgery was optimal--without residual tumor. Recurrence of the disease was detected in 12-48 months in 80.9% of the cases. Three variants of recurrence was revealed by ultrasonography: isolated peritoneal dissemination, in 14.2% of the cases, which was mainly detected during the first 12 months; single entities in the projection of the small pelvis (61.9%) and mixed form (local lesions of small pelvis and peritoneal dissemination) in 23.8% of the cases.

To determine the clinical manifestations and optimal management of female patients with advanced colorectal cancer (CRC) metastasis in ovaries mimicking advanced ovarian malignancy. A retrospective medical records review of female patients with primary CRC metastasis to ovaries, which were initially diagnosed as ovarian malignancy, and treated between 2001 and 2013. Clinical presentations, pathologic findings, and treatment outcomes were analyzed. In total, 19 cases were collected in the study through a hospital tumor registry. The mean age of the patients at the time of diagnosis was 45 years (range, 28-63 years). The most common symptoms were abdominal pain or increased abdominal girth (63%). None of them had rectal bleeding. The ratio of cancer antigen-125 to carcinoembryonic antigen was available in 13 out 19 patients (less than 25 in 76.9%). Barium enema or colonoscopic exam was only performed in 10 outpatients. None of them had a positive finding. All 19 patients went for surgery, all of them had ovarian metastasis but only eight of them had bilateral involvement, and 14 of them had carcinomatosis. All patients went for either optimal cytoreduction surgery or suboptimal cytoreduction surgery. The patients who received optimal cytoreduction surgery had a significant better progression-free and overall survival than those who did not. Clinical manifestations of primary CRC with ovarian metastasis may be confused with advanced ovarian cancer. Negative barium enema or colonoscopic exam cannot rule out the possibility of CRC. For patients with a cancer antigen-125 to carcinoembryonic antigen ratio less than 25, 76% are good reference of CRC metastasis to ovaries. Optimal cytoreduction surgery like that used for treating advanced ovarian cancer had a better prognosis than suboptimal cytoreduction colorectal cancer treatment. Copyright © 2017.

5-aminolevulinic acid (ALA) is a precursor of haemoglobin which leads to the synthesis of porphyrins in malignant gliomas which then appears with red fluorescence under blue light. In the literature we see that there is class Ib evidence that 5-ALA guided surgery significantly increases the radicalism of surgery and gives rise to a marked improvement in 6-month progression-free survival and that there is now class II evidence confirming the value of maximal cytoreductive surgery. Furthermore, existing class II evidence indicates that there is a synergistic effect between aggressive cytoreductive surgery and radiochemotherapy.

Interval debulking surgery in advanced epithelial ovarian cancer.

Pecorelli, Sergio; Odicino, Franco; Favalli, Giuseppe

Cytoreductive surgery and chemotherapy are the mainstay for the treatment of advanced epithelial ovarian cancer. In order to minimize the tumour burden before chemotherapy, cytoreductive surgery is usually performed first. The importance of the amount of residual disease as the main prognostic factor for patients suffering from advanced disease has been almost universally accepted even in the absence of prospective randomized trials addressing the benefit of cytoreductive surgery. In the last decade, the value of debulking surgery after induction chemotherapy - interval debulking surgery, IDS - has been widely debated, especially after the completion of a prospective randomized study from the EORTC addressing the introduction of a surgical procedure with debulking intent preceded and followed by cytoreductive chemotherapy. The rationale of such a strategy in the context of the primary treatment of advanced ovarian cancer lies in a higher cytoreductibility to the 'optimal' status forwarded, and possibly facilitated, by chemotherapy. The results demonstrated a prolongation of both progression-free survival and median survival in favour of patients randomized to IDS (5 and 6 months, respectively). Multivariate analysis revealed IDS to be an independent prognostic factor which reduced the risk of death by 33% at 3 years and by 48% in subsequent re-evaluation after more than 6 years of observation. Despite the above, results have been questioned by many, leading the GOG to perform a similar study which has been concluded very recently. Nevertheless, the main concern regarding the application of IDS in all instances relates to the morbidity of two major surgical procedures integrated within a short period during which cytotoxic chemotherapy is also administered. Neoadjuvant chemotherapy has been recently proposed to avoid a non-useful surgical procedure in patients considered 'optimally unresectable' after diagnosis of advanced ovarian cancer. Whether or not this newer approach will translate into a longer survival with a better quality of life is going to be addressed by a novel EORTC study. Finally, the concept of a 'chemical' cytoreduction preceding and facilitating a subsequent 'surgical' effort has been recently introduced also in the treatment of recurrent disease. The EORTC has recently initiated a prospective randomized study (LOROCSON - Late Onset Recurrent Ovarian Cancer: Surgery or Not) to validate the importance of such an approach to be balanced with medical treatment alone not only in terms of survival but also as far as quality of life is concerned.

INTRODUCTION Cytoreductive surgery (CRS) along with hyperthermic intraperitoneal chemotherapy (HIPEC) is the treatment of choice for selected patients with peritoneal carcinomatosis, a previously lethal condition with dismal survival rates. METHODS We reviewed CRS and HIPEC procedures performed at our centre from January 1997 to December 2012, focusing on perioperative events and anaesthetic implications. RESULTS In total, 111 patients underwent 113 procedures. Mean age of the patients was 51.7 (range 14–74) years and 84.1% were women. Mean duration of surgery was 9 hours 10 minutes ± 2 hours 56 minutes. Most tumours were ovarian or colorectal in origin, and the mean peritoneal cancer index (PCI) score was 14.3 ± 8.9. Mean estimated blood loss was 1,481 ± 1,064 mL. Mean total intravenous fluids and blood products administered was 8,498 ± 3,941 mL. Postoperatively, 79.5% of the patients needed intensive care, as 75.2% of the 113 procedures required interval extubation. Patients with lower PCI scores were more likely to be extubated immediately after surgery (p < 0.05). 80.0% of patients had coagulopathy postoperatively, and this was associated with longer HIPEC duration (p < 0.05). Median lengths of intensive care unit and hospital stays were two days and 14 days, respectively. Longer duration of surgery significantly correlated with longer hospitalisation. Prolonged hospitalisation was due to nosocomial pneumonia, pleural effusions, respiratory failure, sepsis, surgical complications (such as anastomotic or wound dehiscence), and intra-abdominal infections. CONCLUSION The CRS and HIPEC technique is a major surgery with significant morbidity, as highlighted by the perioperative concerns observed in our study. PMID:27121920

To investigate opioid use and pain scores associated with incisional injection of liposomal bupivacaine compared with bupivacaine hydrochloride after laparotomy for gynecologic malignancies. A retrospective cohort study was conducted to compare abdominal incision infiltration with liposomal bupivacaine with bupivacaine hydrochloride after modification of a pre-existing enhanced recovery pathway. Patients undergoing staging laparotomy or complex cytoreductive surgery under the updated pathway were compared with patients treated under the original pathway (historic controls). Endpoints included cumulative opioid use (primary outcome) in oral morphine equivalents and cumulative pain score. In the complex cytoreductive cohort, median oral morphine equivalents were lower in the liposomal bupivacaine group through 24 hours (30 compared with 53.5 mg, P=.002), 48 hours (37.5 compared with 82.5 mg, P=.005), and the length of stay (62 compared with 100.5 mg, P=.006). Fewer liposomal bupivacaine patients required intravenous rescue opioids (28.9% compared with 55.6%, P<.001) or patient-controlled analgesia (4.1% compared with 33.3%, P<.001). Cumulative pain score was no different between groups through 48 hours (161 compared with 158, P=.69). Postoperative nausea and ileus were less frequent in patients receiving liposomal bupivacaine. Median hospital stay was 5 days in both groups. In the staging laparotomy cohort, cumulative opioids and cumulative pain score were no different between groups (through 48 hours: 162 compared with 161, P=.62; 38 compared with 38, P=.68, respectively). Intravenous rescue opioids (15.3% compared with 28.6%, P=.05) and patient-controlled analgesia (1.4% compared with 8.3%, P=.05) were used less frequently in the liposomal bupivacaine group. Median hospital stay was 4 days in both groups. Despite the higher cost of liposomal bupivacaine, total pharmacy costs did not differ between groups. Abdominal incision infiltration with liposomal bupivacaine was associated with less opioid and patient-controlled analgesia use with no change in pain scores compared with bupivacaine hydrochloride after complex cytoreductive surgery for gynecologic malignancies. Improvements were also seen in patients undergoing staging laparotomy.

Primary cytoreductive surgery (PDS) followed by platinum-based chemotherapy is the cornerstone of treatment and the absence of residual tumor after PDS is universally considered the most important prognostic factor. The aim of the present analysis was to evaluate trend and predictors of 30-day mortality in patients undergoing primary cytoreduction for ovarian cancer. Literature was searched for records reporting 30-day mortality after PDS. All cohorts were rated for quality. Simple and multiple Poisson regression models were used to quantify the association between 30-day mortality and the following: overall or severe complications, proportion of patients with stage IV disease, median age, year of publication, and weighted surgical complexity index. Using the multiple regression model, we calculated the risk of perioperative mortality at different levels for statistically significant covariates of interest. Simple regression identified median age and proportion of patients with stage IV disease as statistically significant predictors of 30-day mortality. When included in the multiple Poisson regression model, both remained statistically significant, with an incidence rate ratio of 1.087 for median age and 1.017 for stage IV disease. Disease stage was a strong predictor, with the risk estimated to increase from 2.8% (95% confidence interval 2.02-3.66) for stage III to 16.1% (95% confidence interval 6.18-25.93) for stage IV, for a cohort with a median age of 65 years. Metaregression demonstrated that increased age and advanced clinical stage were independently associated with an increased risk of mortality, and the combined effects of both factors greatly increased the risk.

The incidence of venous thromboembolism (VTE) in peritoneal malignancies can approach 30 to 50 per cent without prophylaxis. Prophylaxis in cytoreductive surgeries (CRS) presents a challenge to preoperative heparin-based therapy because of an increased risk of coagulopathy and potential for bleeding. Herein, we report the large series of CRS and hyperthermic intraperitoneal chemotherapy receiving dextran-40 prophylaxis. Retrospective chart review of peritoneal malignancies patients undergoing CRS at University of Nebraska Medical Center identified 69 individuals who received dextran-40 between 2010 and 2013. The incidences of VTEs, perioperative bleeding, complications, morbidity, and mortality were determined in-hospital and at 90 days. Of the 69 patients treated, the 30-day VTE rate was 8.7 per cent, and no pulmonary embolisms, bleeding, anaphylactoid reaction, or mortality were observed with dextran usage. The specific VTE events included three upper extremity and three lower extremity VTEs. No additional VTE events were identified between 30 and 90 days. In conclusion, dextran-40 prophylaxis was not associated with any perioperative bleeding events, and the observed incidence of VTE was comparable to reported heparin-based prophylaxis in CRS/hyperthermic intraperitoneal chemotherapy patients. This data supports further exploration of dextran-40 as a VTE prophylactic agent in complex surgical oncology cases.

Patients with PMCA commonly undergo surgery before CRS/HIPEC. We evaluated the role of extensive surgical treatment before CRS/HIPEC in terms of overall survival (OS). 105 patients with PMCA who underwent a CRS/HIPEC procedure were identified from a prospective database. Patients were divided into two groups based on Prior Surgery Score (PSS): PSS ≤ 1 limited surgery group (LSG), PSS >1 extensive surgery group (ESG). Survival of lymph node (LN) negative and positive patients was analyzed separately. 40 patients were in LSG and 65 in ESG. Mean time from diagnosis to CRS/HIPEC was 6 and 17 months for LSG and ESG, respectively (p = 0.004). Groups were well balanced in peritoneal cancer index, complete cytoreduction rate, and LN status. One, 3, and 5-year OS among LN negative patients was 95, 83, and 75% for the LSG (n = 22) group and 87, 55, and 32% for the ESG (n = 35), group respectively (p = 0.026). One, 3, and 5-year OS among LN positive patients was 69, 50, and 17% for the LSG (n = 18) group and 80, 21, and 14% for the ESG (n = 30), group respectively (p = 0.613). For all patients 1, 3, and 5-year OS was 84, 65, and 54% for the LSG (n = 40) group and 86, 43, and 26% for the ESG (n = 65) group, respectively (p = 0.029). Extensive surgical treatment before CRS/HIPEC is associated with delay of CRS/HIPEC and poorer OS overall, especially among LN negative patients. We recommend early referral of PMCA patients to a peritoneal surface malignancy center. Copyright © 2015 Elsevier Ltd. All rights reserved.

Background. Peritoneal Carcinomatosis Index (PCI) is a widely established scoring system that describes disease burden in isolated colorectal peritoneal carcinomatosis (CPC). Its significance may be diminished with complete cytoreduction. We explore the utility of the recently described Peritoneal Surface Disease Severity Score (PSDSS) and compare its prognostic value against PCI. Methods. The endpoints were overall survival (OS), progression-free survival (PFS), and survival less than 18 months (18 MS). Results. Fifty patients underwent cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) for CPC from 2003 to 2014, with 98% achieving complete cytoreduction. Median OS was 28.8 months (95% CI, 18.0–39.1); median PFS was 9.4 months (95% CI, 7.7–13.9). Univariate analysis showed that higher PCI was significantly associated with poorer OS (HR 1.11; 95% CI, 1.03–1.20) and PFS (HR 1.09; 95% CI, 1.03–1.14). Conversely, PSDSS was not associated with either endpoint. Multivariate analysis showed that PCI, but not PSDSS, was predictive of OS and PFS. PCI was also able to discriminate survival outcomes better than PSDSS for both OS and PFS. There was no association between 18 MS and either score. Conclusion. PCI is superior to PSDSS in predicting OS and PFS and remains the prognostic score of choice in CPC patients undergoing CRS/HIPEC. PMID:27006828

Achieving complete cytoreduction of peritoneal surface malignancies (PSM) can be challenging. In most cases, delivery of heated intra-peritoneal chemotherapy (HIPEC) is straightforward. However, using the closed technique in some cases may be technically challenging; for example, in patients requiring abdominal closure using a large synthetic mesh. In cases where groin hernias are present, it is imperative to resect the hernia sac, since it may contain tumor deposits. In cases with major inguinal involvement where disease may spread out of the hernia sac or in cases where a hernia repair was performed while disease is present, inguinal perfusion should be considered. To describe our experience with combined intra-peritoneal and inguinal perfusion of HIPEC following cytoreductive surgery. This is a retrospective review of all patients who underwent cytoreductive surgery (CRS) and HIPEC at our institution. A prospectively maintained database containing data of patients treated by CRS and HIPEC (n=122) was reviewed. All patients with macroscopic inguinal involvement by PSM with complete cytoreduction perfused by HIPEC were included. We identified five cases who underwent CRS and combined intraperitoneal and inguinal perfusion after resection of large inguinal tumor deposits (n=4) or after a recent hernia repair with hernial sac involvement by mucinous adenocarcinoma (n=1). All five patients were successfully perfused using an additional outflow catheter placed in the groin. In cases of inguinal involvement by PSM, complete cytoreduction should be achieved and perfusion of the involved groin considered as it is feasible and safe.

To compare the perioperative outcomes of minimally invasive secondary cytoreduction surgery (SCS) plus hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) versus open surgery plus HIPEC in a group of platinum-sensitive patients with advanced epithelial ovarian cancer (AEOC) with isolated relapse. Retrospective cohort study (Canadian Task Force classification II-2). Department of Obstetrics and Gynecology, Division of Gynecologic Oncology, Catholic University of the Sacred Heart, Rome, Italy. We selected 22 patients with a peritoneal cancer index value of 2. The laparoscopic group consisted of 11 patients who underwent laparoscopic and/or robotic complete cytoreduction plus HIPEC, whereas the laparotomic group consisted of 11 patients who underwent complete laparotomic cytoreduction plus HIPEC. The minimally invasive surgery (MIS) group were platinum-sensitive single recurrent ovarian cancer patients who underwent either laparoscopic or robotic complete secondary cytoreduction plus HIPEC, whereas the open group were women with similar clinical characteristics who underwent complete secondary cytoreduction plus HIPEC by laparotomy. The median operative time, calculated from the skin incision to the end of SCS (i.e., excluding HIPEC phase) was 125 min (range 95-150 min) in the MIS group and 295 min (range 180-420) in the open group (p = .001), with a median estimated blood loss of 50 mL (range 50-100) and 500 mL (range 50-1300), respectively (p = .025). The median length of hospital stay was 4 days (range 3-17) in the MIS group and 8.5 days (range 4-30) in the open group (p = .002). No statistically significant differences were registered in terms of intra- and postoperative complications between the 2 groups. The minimally invasive approach for SCS plus HIPEC is safe and efficient in terms of toxicity and postoperative outcomes for single isolated relapse. HIPEC should not be considered a major contraindication to a minimally invasive approach. Copyright © 2015 AAGL. Published by Elsevier Inc. All rights reserved.

Appendix adenocarcinomas are rare tumors with propensity for peritoneal metastasis. Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy is an established treatment with curative intent, but, to date, studies reporting survival have been heterogeneous with regard to their patient groups (including other tumor types), interventions (not all patients receiving intraperitoneal chemotherapy), and follow-up (varying surveillance protocols). The aim of this study is to quantify the impact of this intervention on survival in a homogeneous group of patients with appendix adenocarcinoma receiving standardized treatment and follow-up, and to determine the impact of prognostic indicators on survival. This is a retrospective analysis of a prospective database at a national peritoneal tumor center where all patients had their appendix pathology reviewed and management planned by a specialized peritoneal tumor multidisciplinary team. Data were extracted on prognostic indicators including peritoneal cancer index, completeness of cytoreduction score, preoperative tumor markers, and histological features. Overall and disease event-free survival from the date of intervention were evaluated using Kaplan Meier curves and univariate Cox proportional hazards regression analysis. A total of 65 patients underwent cytoreductive surgery with hyperthermic intraperitoneal chemotherapy for appendix adenocarcinoma between 2005 and 2015. Median follow-up was 44.3 months. The overall survival was 55.5% and disease event-free survival was 36.1% (5-year rate). Peritoneal Cancer Index <7, complete cytoreduction score of 0, and preoperative CEA of <6 were all associated with significantly higher overall and disease event-free survival. CA19-9 <38 and CA125 <31 were not associated with a significantly higher overall or disease event-free survival. The sample size was limited because of the rarity of this tumor type. This study quantifies the impact of cytoreductive surgery with hyperthermic intraperitoneal chemotherapy on overall and disease event-free survival for appendix adenocarcinoma, identifying key prognostic indicators that may guide treatment. It supports the referral of these rare tumors to specialist centers with appropriate expertise for initial management and follow-up. See Video Abstract at http://www.links.lww.com/DCR/A595.

Optimal primary surgical treatment for advanced epithelial ovarian cancer.

Ovarian cancer is the sixth most common cancer among women. In addition to diagnosis and staging, primary surgery is performed to achieve optimal cytoreduction (surgical efforts aimed at removing the bulk of the tumour) as the amount of residual tumour is one of the most important prognostic factors for survival of women with epithelial ovarian cancer. An optimal outcome of cytoreductive surgery remains a subject of controversy to many practising gynae-oncologists. The Gynaecologic Oncology group (GOG) currently defines 'optimal' as having residual tumour nodules each measuring 1 cm or less in maximum diameter, with complete cytoreduction (microscopic disease) being the ideal surgical outcome. Although the size of residual tumour masses after surgery has been shown to be an important prognostic factor for advanced ovarian cancer, it is unclear whether it is the surgical procedure that is directly responsible for the superior outcome that is associated with less residual disease. To evaluate the effectiveness and safety of optimal primary cytoreductive surgery for women with surgically staged advanced epithelial ovarian cancer (stages III and IV).To assess the impact of various residual tumour sizes, over a range between zero and 2 cm, on overall survival. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2010, Issue 3) and the Cochrane Gynaecological Cancer Review Group Trials Register, MEDLINE and EMBASE (up to August 2010). We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. Retrospective data on residual disease from randomised controlled trials (RCTs) or prospective and retrospective observational studies which included a multivariate analysis of 100 or more adult women with surgically staged advanced epithelial ovarian cancer and who underwent primary cytoreductive surgery followed by adjuvant platinum-based chemotherapy. We only included studies that defined optimal cytoreduction as surgery leading to residual tumours with a maximum diameter of any threshold up to 2 cm. Two review authors independently abstracted data and assessed risk of bias. Where possible, the data were synthesised in a meta-analysis. There were no RCTs or prospective non-RCTs identified that were designed to evaluate the effectiveness of surgery when performed as a primary procedure in advanced stage ovarian cancer.We found 11 retrospective studies that included a multivariate analysis that met our inclusion criteria. Analyses showed the prognostic importance of complete cytoreduction, where the residual disease was microscopic that is no visible disease, as overall (OS) and progression-free survival (PFS) were significantly prolonged in these groups of women. PFS was not reported in all of the studies but was sufficiently documented to allow firm conclusions to be drawn.When we compared suboptimal (> 1 cm) versus optimal (< 1 cm) cytoreduction the survival estimates were attenuated but remained statistically significant in favour of the lower volume disease group There was no significant difference in OS and only a borderline difference in PFS when residual disease of > 2 cm and < 2 cm were compared (hazard ratio (HR) 1.65, 95% CI 0.82 to 3.31; and HR 1.27, 95% CI 1.00 to 1.61, P = 0.05 for OS and PFS respectively).There was a high risk of bias due to the retrospective nature of these studies where, despite statistical adjustment for important prognostic factors, selection bias was still likely to be of particular concern.Adverse events, quality of life (QoL) and cost-effectiveness were not reported by treatment arm or to a satisfactory level in any of the studies. During primary surgery for advanced stage epithelial ovarian cancer all attempts should be made to achieve complete cytoreduction. When this is not achievable, the surgical goal should be optimal (< 1 cm) residual disease. Due to the high risk of bias in the current evidence, randomised controlled trials should be performed to determine whether it is the surgical intervention or patient-related and disease-related factors that are associated with the improved survival in these groups of women. The findings of this review that women with residual disease < 1 cm still do better than women with residual disease > 1 cm should prompt the surgical community to retain this category and consider re-defining it as 'near optimal' cytoreduction, reserving the term 'suboptimal' cytoreduction to cases where the residual disease is > 1 cm (optimal/near optimal/suboptimal instead of complete/optimal/suboptimal).

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is associated with high morbidity. The Quality of Life (QoL) assessment in this patient group with a limited life expectancy and high recurrence rate is important. Published data show an impairment of postoperative Quality of Life at 3 months postoperatively with an improvement over 6-12 months at levels higher than the baseline. Standardized instruments QoL have to be included in clinical trials assessing the efficacy of CRS and HIPEC. (c) 2009 Wiley-Liss, Inc.

To evaluate the oncological outcomes of patients with metastatic renal cell carcinoma (mRCC) involving the inferior vena cava (IVC) who received cytoreductive nephrectomy. This study included 75 consecutive metastatis renal cell carcinoma (mRCC) patients with inferior vena cava (IVC) tumor thrombus undergoing cytoreductive nephrectomy and tumor thrombectomy followed by systemic therapy. Of the 75 patients, 11, 33, 24 and 7 had level I, II, III and IV IVC thrombus, respectively. Following surgical treatment, 25 (group A), 27 (group B) and 23 (group C) received cytokine therapy alone, molecular-targeted therapy alone and both therapies, respectively, as management for metastatic diseases. The median overall survival (OS) of the 75 patients was 16.2 months. No significant differences in OS were noted according to the level of the IVC tumor thrombus. There were no significant differences in OS among groups A, B and C; however, OS in groups B and C was significantly superior to that in group A. Furthermore, multivariate analysis of several parameters identified the following independent predictors of poor OS-elevated C-reactive protein, liver metastasis and postoperative treatment with cytokine therapy alone. The prognosis of mRCC patients with IVC thrombus undergoing cytoreductive nephrectomy may be significantly affected by the type of postoperative systemic therapy rather than the level of the IVC tumor thrombus. Accordingly, cytoreductive nephrectomy should be considered as a major therapeutic option for patients with mRCC involving the IVC, particularly in the era of targeted therapy.

Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy has emerged as one of the primary modalities of treatment of diffuse peritoneal malignancies. It is a complex surgical procedure with the patients facing major and potentially life threatening alterations of haemodynamic, respiratory, metabolic and thermal balance with significant fluid losses and the perioperative management is challenging for anaesthesiologists and intensive care physicians. Though the alterations are short lived, these patients require advanced organ function monitoring and support perioperatively. The anaesthesiologist is involved in the management of haemodynamics, respiratory function, coagulation, haematologic parameters, fluid balance, thermal variations, and metabolic and nutritional support perioperatively. The chemotherapy instillate used are known to cause nephrotoxicity, cardiotoxicity, dyselectrolytemia and lactic acidosis. The preoperative polypharmacy for pain control, previous surgery and/or chemotherapy, malnourished status secondary to feeding problems and tumour wasting syndrome make the task all the more challenging. The anaesthesiologist also needs to consider the perioperative care from a quality of life perspective and proper preoperative counselling is important. The present overview summarizes the challenges faced by the anaesthesiologist regarding the pathophysiological alterations during the Cytoreductive surgery and Hyperthermic intraperitoneal chemotherapy in the preoperative, intraoperative and postoperative periods.

Primary signet-ring cell carcinoma (SRCC) of the breast is an uncommon variant, accounting for 2-4.5% of all primary breast cancers. Secondary SRCC of the endometrium is very rare and usually originates from the breast or gastrointestinal tract. A 54-year-old, postmenopausal woman with a past history of breast cancer four years previously was admitted with abnormal uterine bleeding. An endometrial biopsy revealed undifferentiated adenocarcinoma with signet-ring cells. The patient underwent laparotomy and cytoreductive surgery was performed. Pathological analysis and immunohistochemical tests demonstrated a uterine (endomyometrial) metastasis of breast SRCC. Omentum, peritoneal surfaces and retroperitoneal lymph nodes also included tumoral tissue with signet-ring cell morphology. The patient received adjuvant systemic chemotherapy with adriamycin, cyclophosphamide and paclitaxel. This case report discusses the patient's clinical characteristics and the role of cytoreductive surgery on patient survival in SRCC of the breast metastasizing to the uterus. © 2012 The Authors.

To analyze the 5- and 7-year survival outcomes for women with platinum-sensitive recurrent epithelial ovarian cancer (REOC) who underwent secondary cytoreductive surgery (SCS) plus platinum-based hyperthermic intraperitoneal chemotherapy (HIPEC). From the electronic databases of the Department of Obstetrics and Gynecology at the Catholic University of the Sacred Heart of Rome and of the S. Orsola Hospital, University of Bologna, a consecutive series of REOC patients were selected using the following inclusion criteria: primary platinum-free interval (PFI-1) of 6 months or longer, completeness of secondary cytoreduction score (CC) of 1 or lower, minimum follow-up period of 48 months, Eastern Cooperative Group (ECOG) performance status at recurrence of 1 or less, and platinum-based HIPEC. Progression-free survival (PFS) and post-relapse survival (PRS) were calculated as the time between SCS + HIPEC and secondary recurrence or death, respectively. The final study population included 70 women with platinum-sensitive REOC. The median follow-up time was 73 months (range 48-128 months), and the median PFI-1 was 19 months (range 6-100 months). At the time of recurrence, the median peritoneal cancer index was 7 (range 1-21), and a CC score of 0 was achieved for 62 patients (88.6 %). As the HIPEC drug, we used oxaliplatin in 17 cases (38.6 %) and cisplatin in 43 cases (61.4 %). No postoperative deaths were observed, and the complication rate for grades 3 and 4 disease was 8.6 %. The median PFS duration was 27 months (range 5-104 months), and the 5- and 7-year PRS rates were respectively 52.8 and 44.7 %, (median PRS 63 months). The current study demonstrated favorable 5- and 7-year PRS rates for platinum-sensitive REOC patients undergoing SCS + HIPEC, which encourages the inclusion of patients in randomized clinical trials for definitive conclusions to be drawn.

To analyze the ability of magnetic resonance imaging (MRI) and systematic evaluation at surgery to predict optimal cytoreduction in primary advanced ovarian cancer and to develop a preoperative scoring system for cancer staging. Preoperative MRI and standard laparotomy were performed in 99 women with either ovarian or primary peritoneal cancer. Using univariate and multivariate logistic regression analysis of a systematic description of the tumor in nine abdominal compartments obtained by MRI and during surgery plus clinical parameters, a scoring system was designed that predicted non-optimal cytoreduction. Non-optimal cytoreduction at operation was predicted by the following: (A) presence of comorbidities group 3 or 4 (ASA); (B) tumor presence in multiple numbers of different compartments, and (C) numbers of specified sites of organ involvement. The score includes: number of compartments involved (1-9 points), >1 subdiaphragmal location with presence of tumor (1 point); deep organ involvement of liver (1 point), porta hepatis (1 point), spleen (1 point), mesentery/vessel (1 point), cecum/ileocecal (1 point), rectum/vessels (1 point): ASA groups 3 and 4 (2 points). Use of the scoring system based on operative findings gave an area under the curve (AUC) of 91% (85-98%) for patients in whom optimal cytoreduction could not be achieved. The score AUC obtained by MRI was 84% (76-92%), and 43% of non-optimal cytoreduction patients were identified, with only 8% of potentially operable patients being falsely evaluated as suitable for non-optimal cytoreduction at the most optimal cut-off value. Tumor in individual locations did not predict operability. This systematic scoring system based on operative findings and MRI may predict non-optimal cytoreduction. MRI is able to assess ovarian cancer with peritoneal carcinomatosis with satisfactory concordance with laparotomic findings. This scoring system could be useful as a clinical guideline and should be evaluated and developed further in larger studies. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Danger-associated molecular patterns (DAMPs) can elicit immune responses and may subsequently induce an immune-suppressed state. Previous work showed that increased plasma levels of DAMPs are associated with immune suppression and increased susceptibility toward infections in trauma patients. Like trauma, major surgical procedures, such as cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC), are also thought to cause profound DAMP release. Furthermore, the incidence of postoperative infections in these patients, ranging from 10 to 36%, is very high compared to that observed in patients undergoing other major surgical procedures. We hypothesized that the double hit of surgical trauma (CRS) in combination with HIPEC causes excessive DAMP release, which in turn contributes to the development of immune suppression. To investigate this, we assessed DAMP release in patients undergoing CRS-HIPEC, and investigated its relationship with immune suppression and postoperative infections. In 20 patients undergoing CRS-HIPEC, blood was obtained at five time points: just before surgery (baseline), after CRS, after HIPEC, at ICU admission, and 1 day after surgery. Circulating levels of DAMPs [heat shock protein (HSP)70, high mobility group box (HMGB)1, S100A12, S100A8/S100A9, nuclear (n)DNA, mitochondrial (mt)DNA, lactate dehydrogenase (LDH), a marker of unscheduled cell death], and cytokines [tumor necrosis factor (TNF)α, IL-6, IL-8, IL-10, macrophage inflammatory protein (MIP)-1α, MIP-1β, and MCP-1] were measured. The extent of immune suppression was determined by measuring HLA-DR gene expression and ex vivo leukocytic cytokine production capacity. Plasma levels of DAMPs (maximum fold increases of HSP70: 2.1 [1.5-2.8], HMGB1: 5.9 [3.2-9.8], S100A8/S100A9: 3.6 [1.8-5.6], S100A12: 2.6 [1.8-4.3], nDNA 3.9 [1.0-10.8], LDH 1.7 [1.2-2.5]), and all measured cytokines increased profoundly following CRS-HIPEC. Evidence of immune suppression was already apparent during the procedure, illustrated by a decrease of HLA-DR expression compared with baseline (0.5-fold [0.3-0.9]) and diminished ex vivo pro-inflammatory cytokine production capacity. The increase in HMGB1 levels correlated with the decrease in HLA-DR expression ( r  = -0.46, p  = 0.04), and peak HMGB1 concentrations were significantly higher in the five patients who went on to develop a postoperative infection (p = 0.04). CRS-HIPEC is associated with profound DAMP release and immune suppression, and plasma HMGB1 levels are related with the occurrence of postoperative infections in these patients.

Optimum cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is essential for the curative treatment of peritoneal carcinomatosis of colorectal origin. At present, surgeons depend on visual inspection and palpation for tumour detection. Improved detection of tumour tissue using molecular fluorescence-guided surgery could not only help attain a complete cytoreduction of metastatic lesions, but might also prevent overtreatment by avoiding resection of benign lesions. For this non-randomised, single-centre feasibility study, we enrolled patients with colorectal peritoneal metastases scheduled for cytoreductive surgery and HIPEC. 2 days before surgery, 4·5 mg of the near-infrared fluorescent tracer bevacizumab-IRDye800CW was administered intravenously. The primary objectives were to determine the safety and feasibility of molecular fluorescence-guided surgery using bevacizumab-IRDye800CW. Molecular fluorescence-guided surgery was deemed safe if no allergic or anaphylactic reactions were recorded and no serious adverse events were attributed to bevacizumab-IRDye800CW. The technique was deemed feasible if bevacizumab-IRDye800CW enabled detection of fluorescence signals intraoperatively. Secondary objectives were correlation of fluorescence with histopathology by back-table imaging of the fresh surgical specimen and semi-quantitative ex-vivo analyses of formalin-fixed paraffin embedded (FFPE) tissue on all peritoneal lesions. Additionally, VEGF-α staining and fluorescence microscopy was done. This study is registered with the Netherlands Trial Registry, number NTR4632. Between July 3, 2014, and March 2, 2015, seven patients were enrolled in the study. One patient developed an abdominal sepsis 5 days postoperatively and another died from an asystole 4 days postoperatively, most probably due to a cardiovascular thromboembolic event. However, both serious adverse events were attributed to the surgical cytoreductive surgery and HIPEC procedure. No serious adverse events related to bevacizumab-IRDye800CW occurred in any of the patients. Intraoperatively, fluorescence was seen in all patients. In two patients, additional tumour tissue was detected by molecular fluorescence-guided surgery that was initially missed by the surgeons. During back-table imaging of fresh surgical specimens, a total of 80 areas were imaged, marked, and analysed. All of the 29 non-fluorescent areas were found to contain only benign tissue, whereas tumour tissue was detected in 27 of 51 fluorescent areas (53%). Ex-vivo semi-quantification of 79 FFPE peritoneal lesions showed a tumour-to-normal ratio of 6·92 (SD 2·47). Molecular fluorescence-guided surgery using the near-infrared fluorescent tracer bevacizumab-IRDye800CW is safe and feasible. This technique might be of added value for the treatment of patients with colorectal peritoneal metastases through improved patient selection and optimisation of cytoreductive surgery. A subsequent multicentre phase 2 trial is needed to make a definitive assessment of the diagnostic accuracy and the effect on clinical decision making of molecular fluorescence-guided surgery.

[Cost of an intraperitoneal chemohyperthermia (IPCH) related to cytoreductive surgery].

A complete cytoreductive surgery followed with an intraperitoneal chemohyperthermia (IPCH) is a new treatment allowing curing some patients with a peritoneal carcinomatosis. The cost of this treatment, evaluated in different countries, is high. In France, we do not have any cost evaluation of this therapy, and this state slows its diffusion in our country. The aim of this study is to evaluate the real cost of maximal cytoreductive surgery with IPCH, and to compare it with the financial support given by the Ministery of Health. The real cost of this therapy was established on the standard analytic accountancy of our Institute. The analysis of the financial support received was done after the classification of the patients in the current official diagnosis-related groups, and according to the current rates of reimbursing of these acts. Seventy-three patients were treated with IPCH in our Institute during 2002 and 2003. The real mean cost for our hospital was 39,358 euros per patient, with a mean hospital staying of 27.7 days. In counterpart, our hospital received a mean financial support of 20,485 euros, resulting in a deficit of 18,873 euros per patient (and close to 1.4 million of euros for the two years). Our current classification of diagnosis-related groups does not allow to describe the real importance of this therapy which combines a maximal cytoreductive surgery with IPCH. In our system of reimbursing, the hospital which offers this type of new therapy to its patients receives only half of the real rate. Two correctives measures are suitable: to describe this combining treatment in the official list of medical acts, and to determine its specific cost for reimbursing.

Purpose To investigate whether initial diagnostic laparoscopy can prevent futile primary cytoreductive surgery (PCS) by identifying patients with advanced-stage ovarian cancer in whom > 1 cm of residual disease will be left after PCS. Patients and Methods This multicenter, randomized controlled trial was undertaken within eight gynecologic cancer centers in the Netherlands. Patients with suspected advanced-stage ovarian cancer who qualified for PCS were eligible. Participating patients were randomly assigned to either laparoscopy or PCS. Laparoscopy was used to guide selection of primary treatment: either primary surgery or neoadjuvant chemotherapy followed by interval surgery. The primary outcome was futile laparotomy, defined as a PCS with residual disease of > 1 cm. Primary analyses were performed according to the intention-to-treat principle. Results Between May 2011 and February 2015, 201 participants were included, of whom 102 were assigned to diagnostic laparoscopy and 99 to primary surgery. In the laparoscopy group, 63 (62%) of 102 patients underwent PCS versus 93 (94%) of 99 patients in the primary surgery group. Futile laparotomy occurred in 10 (10%) of 102 patients in the laparoscopy group versus 39 (39%) of 99 patients in the primary surgery group (relative risk, 0.25; 95% CI, 0.13 to 0.47; P < .001). In the laparoscopy group, three (3%) of 102 patients underwent both primary and interval surgery compared with 28 (28%) of 99 patients in the primary surgery group ( P < .001). Conclusion Diagnostic laparoscopy reduced the number of futile laparotomies in patients with suspected advanced-stage ovarian cancer. In women with a plan for PCS, these data suggest that performance of diagnostic laparoscopy first is reasonable and that if cytoreduction to < 1 cm of residual disease seems feasible, to proceed with PCS.

Complete cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has changed the therapeutic landscape, improving overall survival in patients with peritoneal carcinomatosis with a colonic origin. The main limitation of this aggressive locoregional procedure, however, is extra-abdominal or distant spread. The objective of this study was to identify the prognostic value of circulating tumor cells (CTCs) in patients with peritoneal carcinomatosis of colonic origin undergoing CRS + HIPEC. Fourteen patients diagnosed with peritoneal carcinomatosis from colon cancer and suitable for potentially curative treatment with CRS + HIPEC were included in this study. CTCs were isolated from the peripheral blood by immunomagnetic techniques by the use of a multi-cytokeratin-specific antibody and detected via immunocytochemical methods. The phenotypic characterization of EGFR on CTCs was analyzed by immunofluorescence. At baseline, 50% of the patients were positive for CTCs, with a mean value of 5.5 CTCs per 10 mL of peripheral blood. After surgery, 28.57% of the patients presented CTCs, with a mean value of 6.75 CTCs per 10 mL. A positive correlation was found between the presence of CTC-negative, epidermal growth factor receptor-positive at baseline and the patients who had symptoms of intestinal obstruction (21.4%). In addition, the presence of CTCs identified patients with distant dissemination and was also significantly correlated with progression-free survival (P = .0024). The detection and characterization of CTCs are good prognostic and predictive markers in patients with peritoneal carcinomatosis resulting from colon cancer. These analyses could be used as a new tool to identify subpopulations of patients who could benefit from CRS + HIPEC treatment. Copyright © 2016 Elsevier Inc. All rights reserved.

The modified Glasgow prognostic score (incorporating C-reactive protein and albumin) predicts survival in patients with gastro-intestinal tract cancer but has not been evaluated in patients with peritoneal malignancy. The aim was to evaluate the modified Glasgow score preoperatively in patients undergoing complete cytoreductive surgery (CCRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) for pseudomyxoma peritonei (PMP) of appendiceal origin. Prospectively collected data from patients with PMP of appendiceal origin following CCRS and HIPEC between January 2007 and December 2011 were analysed. The mGPS was calculated from preoperative C-reactive protein and albumin. Predicted overall survival (OS) and disease-free survival (DFS) for each mGPS score were calculated using the Kaplan-Meier model. In a separate analysis, a comparison was made between mGPS and Tumour Markers (TM). 260 patients were included in the study. The mGPS of 0, 1, and 2 were found in 111, 130, and 19 patients respectively. The median follow-up was 48 months. For mGPS-0, -1, and -2, the predicted OS was 82.2, 73.7, and 69.2 months and the DFS was 73.5, 62.9, and 54.4 months respectively. As mGPS increases, there is a reduction in long-term survival. There was no difference between mGPS and TM. Preoperative mGPS may be a cost effective prognostic tool for predicting OS and DFS in patients following complete CRS-HIPEC, and performs well compared to TM for predicting patients at high risk of recurrence.

Posterior fossa ependymoma comprises two distinct molecular variants termed EPN_PFA and EPN_PFB that have a distinct biology and natural history. The therapeutic value of cytoreductive surgery and radiation therapy for posterior fossa ependymoma after accounting for molecular subgroup is not known. Four independent nonoverlapping retrospective cohorts of posterior fossa ependymomas (n = 820) were profiled using genome-wide methylation arrays. Risk stratification models were designed based on known clinical and newly described molecular biomarkers identified by multivariable Cox proportional hazards analyses. Molecular subgroup is a powerful independent predictor of outcome even when accounting for age or treatment regimen. Incompletely resected EPN_PFA ependymomas have a dismal prognosis, with a 5-year progression-free survival ranging from 26.1% to 56.8% across all four cohorts. Although first-line (adjuvant) radiation is clearly beneficial for completely resected EPN_PFA, a substantial proportion of patients with EPN_PFB can be cured with surgery alone, and patients with relapsed EPN_PFB can often be treated successfully with delayed external-beam irradiation. The most impactful biomarker for posterior fossa ependymoma is molecular subgroup affiliation, independent of other demographic or treatment variables. However, both EPN_PFA and EPN_PFB still benefit from increased extent of resection, with the survival rates being particularly poor for subtotally resected EPN_PFA, even with adjuvant radiation therapy. Patients with EPN_PFB who undergo gross total resection are at lower risk for relapse and should be considered for inclusion in a randomized clinical trial of observation alone with radiation reserved for those who experience recurrence. © 2016 by American Society of Clinical Oncology.

Adjuvant Bidirectional Chemotherapy Using an Intraperitoneal Port

PubMed Central

Sugarbaker, Paul H.; Bijelic, Lana

2012-01-01

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been established as treatment options for patients with peritoneal metastases or peritoneal mesothelioma. However, this novel treatment strategy remains associated with a large percentage of local-regional treatment failures. These treatment failures are attributed to the inadequacy of HIPEC to maintain a surgical complete response. Management strategies to supplement CRS and HIPEC are indicated. A simplified approach to the intraoperative placement of an intraperitoneal port for adjuvant bidirectional chemotherapy (ABC) was devised. Four different chemotherapy treatment plans were utilized depending upon the primary site of the malignancy. Thirty-one consecutive patients with an intraoperative placement of the intraperitoneal port were available for study. The incidence of adverse events that caused an early discontinuation of the bidirectional chemotherapy occurred in 75% of the 8 patients who had an incomplete cytoreduction and in 0% of patients who had a complete cytoreduction. All of the patients who had complete cytoreduction completed at least 5 of the scheduled 6 bidirectional chemotherapy treatments. Adjuvant bidirectional chemotherapy is possible following a major cytoreductive surgical procedure using a simplified method of intraoperative intraperitoneal port placement. PMID:22888340

A retrospective study of anal sac tumours without pulmonary metastases, from the author's clinical records for the period July 1989 to July 2002, was conducted to establish the response to treatment with surgery and melphalan chemotherapy. Of 21 dogs with tumours of the anal sacs 19 had apocrine gland adenocarcinomas of anal sac origin, one had a benign papillary cystadenoma and another had a malignant melanoma. Two of the 19 dogs had bilateral anal sac adenocarcinomas. Ten of the 19 dogs with apocrine gland adenocarcinomas of anal sac origin had sublumbar lymphadenopathy. Five dogs were excluded by their owners from recommended treatment. Fourteen dogs with apocrine gland adenocarcinomas of anal sac origin were treated by surgical cytoreduction and chemotherapy with melphalan. Seven of the 14 dogs had regional lymph node metastases. Cytoreduction was by local excision of the anal sac in all 14 dogs and concurrent removal of the sublumbar retroperitoneal lymph nodes in the seven dogs with regional lymph node metastases. The median survival time of dogs with sublumbar nodal metastasis was 20 months and for dogs with tumour localised to the anal sac the median survival time was 29.3 months. There was no difference in median survival of those dogs with sublumbar metastases compared to those without. This study suggests there is a role for melphalan in the treatment of dogs with anal sac adenocarcinoma when combined with cytoreductive surgery, with treatment survival times and the local recurrence rate of the primary tumour comparing favourably with previously published treatment regimes.

Peritoneal metastases of colorectal origin - cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC). The financial aspect.

The incidence of peritoneal carcinomatosis of colorectal cancer amounts to 5%-15% for synchronous metastases and as much as 40% in cases of local recurrence. Best results are obtained for cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC). This treatment offers much better outcomes, leading to 5-year survival rates of as much as 30%-50%. The procedures require significant experience in abdominal surgery, are time-consuming (mean duration of the procedure ranging from 6 to 8 hours) and are burdened by complications that are due not only to the procedure itself but also to the intraperitoneal administration of the cytostatic drug at elevated temperature (41.5 °C). After the procedure, patients are required to be admitted to intensive care units due to potential complications associated with the extent and duration of the procedure as well as chemotherapy administered in hyperthermia. Postoperative management of these patients requires appropriate experience of the entire medical and nursing team. Cytoreductive surgeries combined with HIPEC as highly specialized medical procedures should be assessed for their potential long-term benefits and their costs should be appropriately calculated with consideration to realistic reimbursement rates. Realistic valuation and reimbursement covering the overall average cost of the procedure is recommended by the National Consultant in Surgical Oncology as well as the ESMO consensus guidelines.

Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC), used to treat peritoneal surface malignancies (PSM), is a complex procedure with significant major morbidity (MM). To investigate the learning curve (LC) of CRS with HIPEC in a new specialized surgical unit with a fully trained senior surgeon and individualize the variables associated with morbidity and oncological results. A total of 290 consecutive patients with PSM were included. Complete CRS with HIPEC was performed in 204 patients. A risk-adjusted sequential probability ratio test was used to assess the LC on the basis of rates of incomplete cytoreduction (IC) and MM. Complete CRS, MM, and mortality rates were 70.4%, 30.4%, and 2.5%, respectively. Tumor histotype, a high peritoneal cancer index (PCI) and the invaded region were the major independent risk factors for IC, whereas previous surgery, high PCI, stomia realization and blood transfusion were predictors of MM. RA-SPRT showed that 140 and 40 cases were needed to achieve the lowest risk of IC and MM, respectively. CRS with HIPEC to treat PSM has a steep LC. Drastic selection has to be made at the beginning, excluding high PCI, rare peritoneal disease and patients previously operated on. Copyright © 2015 Elsevier Ltd. All rights reserved.

The aim was to evaluate the feasibility and the effectiveness of neoadjuvant systemic chemotherapy using FLOT - protocol followed by cytoreductive surgery (CRS), hyperthermic intraperitoneal chemotherapy (HIPEC) followed by systemic chemotherapyand in patients with peritoneal carciriomatosis (PC) from gastric cancer. Twenty six (median age 53 years, range 39 - 71) were scheduled for three cycles of neoadjuvant systemic chemotherapy using bi-weekly FLOT - protocol followed by CRS + HIPEC. Thereafter 3 additional cycles of FLOT were given. During HIPEC in Colliseum technique Oxaliplatin was given in a dosage of 200 mg/m2 and Docetaxel in a dosage of 80 mg/m2. All patients underwent cytoreductive surgery plus HIPEC. Peritoneal Cancer index was > 15 in 3 cases only. Complete resection could be carried out in all cases (CC-O 18, CC-18). Postoperative complication rate was 23% with no mortality within 30 days. Anastomotic leakage rate was 3.2%. Overall survival was 19.0 months with a 2-year survival rate 38%. Regression analysis demonstrated a Peritoneal Cancer Index PCI > 12 as negative factor for survival. Neoadju- vant chemotherapy using FLOT - protocol followed by CRS + HIPEC seems to be associated with prolonged OS in patients with peritoneal carcinomatosis from gastric cancer. This treatment is not recommended for patients with extensive peritoneal involvement and PCI > 12.

Purpose Desmoplastic small round cell tumor (DSRCT), which harbors EWSR1-WT1 t(11;22)(p13:q12) chromosomal translocation, is an aggressive malignancy that typically presents as intra-abdominal sarcomatosis in young males. Given its rarity, optimal treatment has not been defined. Experimental Design We conducted a retrospective study of 187 DSRCT patients treated at MD Anderson Cancer Center over two decades. Univariate and multivariate regression analyses were performed. We determined whether chemotherapy, complete cytoreductive surgery (CCS), hyperthermic intraperitoneal cisplatin (HIPEC), and/or whole abdominal radiation (WART) improve overall survival in DSRCT patients. Critically, since our institutional practice limits HIPEC and WART to patients with less extensive, potentially resectable disease that had benefited from neoadjuvant chemotherapy, a time-variant analysis was performed to evaluate those adjunct treatment modalities. CONCLUSIONS Improved 3- and 5-year overall survival were observed following multidisciplinary treatment that includes ES-based chemotherapy and complete tumor cytoreductive surgery, but few if any patients are cured. Prospective randomized studies will be required to prove whether HIPEC or WART are important. In the meantime, chemotherapy and CCS remain the cornerstone of treatment and provide a solid foundation to evaluate new biologically targeted therapies.

Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemoperfusion (HIPEC) is routinely used to treat certain peritoneal carcinomatoses (PC), but it can be associated with relatively high complication rates, prolonged hospital length of stay, and potential mortality. Our objective was to determine the learning curve (LC) of CRS/HIPEC in our high-volume institution. A total of 370 patients with PC from mucinous appendiceal neoplasms (MAN = 282), malignant peritoneal mesothelioma (MPM = 60), and gastric cancer (GC = 24) were studied. Outcomes analyzed included incomplete cytoreduction (IC), severe morbidity (SM), 60-day mortality, progression-free survival (PFS), and overall survival (OS). Risk-adjusted sequential probability ratio test (RA-SPRT) was employed to assess the LC of CRS/HIPEC for IC and SM using prespecified odds ratio (OR) boundaries derived from previously published data. Risk adjusted-cumulative average probability (RA-CAP) was used to analyze 1-year PFS and 2-year OS. Complete cytoreduction, severe morbidity, and 60-day mortality were 84.2, 30, and 1.9 % respectively. Higher simplified peritoneal cancer index was the major independent risk factor for IC, whereas high-grade histology, IC, and diagnosis of MPM and GC (compared with MAN) were predictors of SM after CRS/HIPEC (p < 0.05). RA-SPRT showed that approximately 180 cases are needed to achieve the lowest risk of IC and SM. Ninety cases were needed to achieve a steady 1-year PFS and 2-year OS in RA-CAP plots. The completeness of cytoreduction, morbidity, and mortality rates for CRS/HIPEC at our institution are comparable to previously reported data. Approximately 180 and 90 procedures are required to improve operative and oncologic outcomes respectively.

Pseudomyxoma peritonei (PMP) is a rare neoplasm of the appendix, which if untreated disseminates throughout the abdominal cavity and generates considerable morbidity. Since 2002 in the UK, patients with PMP have been managed via two nationally commissioned centres. We evaluated referrals and treatment pathways over time at the Manchester centre. Data from all patients referred with suspected PMP were prospectively collected (2002-2015). Definitive treatment was cytoreductive surgery (CRS) and hyperthermic intra-peritoneal chemotherapy (HIPEC). Disease burden was quantified using the Peritoneal Cancer Index (PCI: score 0-39) and complete cytoreduction (CC) defined by scores of 0/1. Novel treatment algorithms were developed for patients with low-grade appendiceal mucinous neoplasm (LAMN) localised to the peri-appendiceal tissue. 817 patients with confirmed PMP were referred increasing from 11 in 2002 to 103 in 2015. Disease burden was high with mean PCI of 31 in the first quartile (Q1), levelling-off to 15,15,17 thereafter (p = 0.002). The proportion of CC0/1 increased from 67% in Q1 to 77% Q2 and 74% Q3/4. Where complete cytoreduction was achieved, 5 and 10-year overall survival was 77% and 66%. The proportion of patients referred with localised LAMN increased over time reaching 25% each year since 2010 (P trend <0.0001). Two-thirds of localised LAMN now undergo laparoscopically-assisted risk-reducing CRS. The establishment of a national treatment centre was associated with an initial presentation of patients with advanced disease. The programme has demonstrated a clear trend over time towards earlier referral and adoption of minimal invasive techniques for localised disease. This article is protected by copyright.

Background Readmission within 30 days is a measure of care quality. Ovarian cancer patients are at high risk for readmission, but specific risk factors are not defined. This study was designed to determine risk factors in patients with ovarian cancer receiving upfront surgery and chemotherapy. Methods The study population was enrolled to GOG 0218. Factors predictive of admission within 30 days of a previous admission or 40 days of cytoreductive surgery were investigated. Categorical variables were compared by Pearson chi-square test, continuous variables by Wilcoxon–Mann–Whitney test. A logistic regression model was used to evaluate independent prognostic factors and to estimate covariate-adjusted odds. All tests were two-tailed, α = 0.05. Results Of 1873 patients, 197 (10.5%) were readmitted, with 59 experiencing >1 readmission. One-hundred-forty-four (73%) readmissions were post-operative (readmission rate 7.7%). Significant risk factors include: disease stage (stage 3 vs 4, p = 0.008), suboptimal cytoreduction (36% vs 64%, p = 0.001), ascites, (p = 0.018), BMI (25.4 vs 27.6, p < 0.001), poor PS (p < 0.001), and higher baseline CA 125 (p = 0.017). Patients readmitted within 40 days of surgery had a significantly shorter interval from surgery to chemotherapy initiation (22 versus 32 days, p < 0.0001). Patients treated with bevacizumab had higher readmission rates in the case of patients with >1 readmission. On multivariate analysis, the odds of re-hospitalization increased with doubling of BMI (OR = 1.81, 95% CI: 1.07–3.07) and PS of 2 (OR = 2.05, 95% CI 1.21–3.48). Conclusion Significant risk factors for readmission in ovarian cancer patients undergoing primary surgery and chemotherapy include stage, residual disease, ascites, high BMI and poor PS. Readmissions are most likely after the initial surgical procedure, a discrete period to target with a prospective intervention. PMID:26335594

To investigate whether patients' altered body composition (measured with bioimpedentiometry), due to a poor nutritional status, predicts the incidence of no residual disease at primary debulking and the risk of complications in patients with newly-diagnosed advanced epithelial ovarian cancer (EOC). Data regarding patients with newly-diagnosed stage IIIC-IV EOC undergoing elective nutritional assessment between December 2016 and March 2017, were prospectively collected. Bioelectrical impedance analysis (BIA) with measurement of BIA-derived phase angle [PhA] at 50KHz, was accomplished. Only patients with disease which was considered resectable at staging laparoscopy were submitted to open primary cytoreduction. The rate of residual tumor (RT)=0 and the incidence of complications were assessed. Seventy patients were included. Fifty-two of them were submitted to primary cytoreduction (74.3%) and 48 (68.6% of the entire cohort, 92.3% of those who underwent primary debulking) had RT=0 at the end of surgery. Median values of PhA were significantly lower in patients with RT>vs. =0 (4.7, range: 3.6-5.8 vs. 5.3, range: 4.2-6.8; p=0.001). Twenty-four (out of the 52 operated) patients (46.2%) developed at least one complication. PhA was significantly lower in patients with vs. without complications (5, range: 3.6-6.4, vs. 5.4, range 4.5-6.8; p=0.03). After multivariable analysis, Fagotti score and PhA were the only independent predictors of residual disease (OR:13.56; 95%CI:1.33-137.6; p=0.027 and 9.24; 1.16-73.43; p=0.036, respectively) and of any complication (OR:4.9;95%CI:1.17-20.6; p=0.03 and 7.27; 1.45-36.4; p=0.01, respectively). Derangement of body composition (likely due to disease-related malnutrition) expressed as a low phase angle, is an independent predictor of residual disease and peri-operative complications at the time of upfront cytoreduction for advanced EOC.

Several studies suggest that young patients may derive less oncologic benefit from surgical resection of cancers compared with older patients. We hypothesized that young patients may have worse outcomes following cytoreductive surgery with hyperthermic intraperitoneal chemoperfusion (CRS/HIPEC) for peritoneal metastases. Perioperative and oncologic outcomes in adolescent and young adults (AYA), defined as younger than age 40 years (n = 135), undergoing CRS/HIPEC between 2001 and 2015 were reviewed and compared with middle-aged adults, defined as aged 40-65 years (n = 684). The two groups were similar with regards to perioperative characteristics except that AYA were more likely to be symptomatic at presentation (65.2 vs. 50.9%, p = 0.003), had lower Charleson comorbidity index (median 6 vs. 8, p < 0.001), were less likely to receive neoadjuvant chemotherapy (32.8 vs. 42.5%, p = 0.042), and had longer operative times (median 543 vs. 493 min, p = 0.010). Postoperative Clavien-Dindo grade 3-4 morbidity was lower in AYA (17 vs. 26%, p = 0.029), and they required fewer reoperations for complications (3.7 vs. 10.4%, p = 0.014). AYA had longer median overall survival (103.6 vs. 73.2 months, p = 0.053). In a multivariate Cox regression analysis, age was an independent predictor of improved overall survival [hazard ratio 0.705; 0.516-0.963, p = 0.028]. Young patients with peritoneal metastases derive similar benefits from CRS/HIPEC as middle-aged patients. Young age should not be a deterrent to consideration of CRS/HIPEC for peritoneal metastases.

The use of adequate fluid therapy during cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) remains controversial. The aim of the study was to assess whether the use of fluid therapy protocol combined with goal-directed therapy (GDT) is associated with a significant change in morbidity, length of hospital stay, and mortality compared to standard fluid therapy. Patients American Society of Anesthesiologists (ASA) II-III undergoing CRS and HIPEC were randomized into two groups. The GDT group (N = 38) received fluid therapy according to a protocol guided by monitored hemodynamic parameters. The control group (N = 42) received standard fluid therapy. We evaluated incidence of major complications, total length of hospital stay, total amount of fluids administered, and mortality rate. The incidence of major abdominal complications was 10.5% in GDT group and 38.1% in the control group (P = 0.005). The median duration of hospitalization was 19 days in GDT group and 29 days in the control group (P < 0.0001). The mortality rate was zero in GDT group vs. 9.5% in the control group (P = 0.12). GDT group received a significantly (P < 0.0001) lower amount of fluid (5812 ± 1244 ml) than the control group (8269 ± 1452 ml), with a significantly (P < 0.0001) lower volume of crystalloids (3884 ± 1003 vs. 68,528 ± 1413 ml). In CRS and HIPEC, the use of a GDT improves outcome in terms of incidence of major abdominal and systemic postoperative complications and length of hospital stay, compared to standard fluid therapy protocol.

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are an established treatment for pseudomyxoma peritonei (PMP), but it is a major surgical procedure and may be associated with long-term morbidity. To date, health-related quality-of-life (HRQL) data among survivors are lacking. A two-period qualitative study investigated patients undergoing CRS-HIPEC for PMP at a national peritoneal tumor center between 2003 and 2011. First, the European Organization for Research and Treatment (EORTC)-QLQ C30 HRQL questionnaire was used longitudinally preoperatively and at postoperative months 3, 6, 9, 12, 18, and 24, then yearly thereafter. Second, it was updated in 2016 as a cross-sectional study. Both studies were compared with age- and sex-matched reference populations (one-way t tests). A total of 553 longitudinal HRQL questionnaires were completed for 137 patients, truncated at 60 months. In the 2016 update, 85 responses were received from 103 survivors (mean follow-up period, 8.11 years). Patients' physical, role, and social function scores were impaired until 12 months postoperatively, after which the scores did not differ significantly from those of with reference populations. Similarly, fatigue, appetite loss, insomnia, and financial difficulties worsened significantly compared with reference populations in the first 12-months and then normalized. In contrast, impaired cognitive function (82.3 vs 88.5; P = 0.017), constipation (13.7 vs 7.3; P = 0.032), and diarrheal symptoms (15.1 vs 4.9; P = 0.0006) persisted through both periods. Global health scores did not differ significantly from those of the reference population. Beyond 12 months postoperatively, CRS-HIPEC for PMP is associated with a good quality of life except for some cognitive functional impairment and bowel disturbances.

Background Completeness of cytoreduction is an independent prognostic factor following cure-intended surgery for peritoneal carcinomatosis (PC). Intraoperative detection of the minimal residual disease may aid in achieving complete cytoreduction. NV1066, a genetically-engineered herpes simplex virus carrying the transgene for green fluorescent protein (GFP), selectively infects cancer cells. NV1066-infected cancer cells express GFP that can be detected by fluorescence laparoscopy. We sought to determine the feasibility of Virally-directed Fluorescent Imaging (VFI) in the intraoperative detection of minimal residual disease following cytoreductive surgery. Methods Human cancer cell lines OCUM-2MD3 (gastric) and JMN (malignant Mesothelioma) were infected with NV1066 at MOIs (multiplicity of infection; ratio of viral particles to cancer cells) of 0.01, 0.1 and 1.0. Viral infectivity was determined by flow cytometry for GFP and cytotoxicity was determined by a colorimetric assay. PC was established in mice by injection of OCUM cells into the peritoneal cavity. Forty-eight hours following intraperitoneal injection of NV1066, two experienced surgeons resected all visible disease and identified mice free of disease. Five independent observers examined these mice by bright-field and fluorescent laparoscopy and documented residual disease as per the peritoneal cancer index. Selective expression of GFP in tumor tissue was evaluated by histology and PCR for the viral gene ICP0. Results In vitro, NV1066 infected, expressed GFP, and killed both cell lines at all MOIs. GFP signal was detected as early as 4-6 hours following infection. GFP signal intensity of infected cells was significantly higher than the autofluorescence of normal cells (230 – 670 -logs). In vivo, macroscopically undetectable tumor nodules by gross examination and conventional bright-field laparoscopy were identified by GFP fluorescence. Following resection, 8 of 13 mice thought to be free of disease were found to have residual disease as identified by green fluorescence (mean number of observations: 5 range: 1-9). Residual disease was most frequently observed in the retroperitoneum, pelvis, peritoneal surface, and liver (inter-observer agreement 99%). Specificity of NV1066 infection to tumor nodules was confirmed by immunohistochemistry and by PCR for viral gene. Conclusion We have demonstrated that virally-directed fluorescent imaging (VFI), a novel molecular imaging technology, can be used for real-time visualization of minimal residual disease following cytoreductive surgery and can improve the completeness of cure-intended resection.

Purpose GOG 152 was a randomized trial of secondary cytoreductive surgery (SCS) in patients with suboptimal residual disease (residual tumor nodule >1 cm in greatest diameter) following primary cytoreductive surgery for advanced stage ovarian cancer. The current analysis was undertaken to evaluate the impact of disease findings at SCS on progression-free survival (PFS) and overall survival (OS). Methods Among the 550 patients enrolled on GOG-152, two-hundred-sixteen patients were randomly assigned following 3 cycles of cisplatin and paclitaxel to receive SCS. In 15 patients (7%) surgery was declined or contraindicated. In the remaining 201 patients the operative and pathology reports were utilized to classify their disease status at the beginning of SCS as; no gross disease/microscopically negative N= 40 (19.9%), no gross disease/microscopically positive N= 8 (4.0%), and gross disease N=153 (76.1%). Results The median PFS for patients with no gross disease/microscopically negative was 16.1 months, no gross disease/microscopically positive was 13.5 months and for gross disease was 11.7 months, p=0.002. The median OS for patients with no gross disease/microscopically negative was 51.5 months, no gross disease/microscopically positive was 42.6 months and for gross disease was 34.9 months, p=0.018. Conclusion Although as previously reported SCS did not change PFS or OS, for those who underwent the procedure, their operative and pathologic findings were predictive of PFS and OS. Surgical/pathological residual disease is a biomarker of response to chemotherapy and predictive of PFS and OS. PMID:27692669

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.

Most of the ovarian cancers are diagnosed at advanced stages. As peritoneal carcinomatosis increases, especially when it extends to the diaphragm and intestinal mesos, probability of obtaining complete cytoreduction is reduced. Complete cytoreduction (residue zero: R0) is one of the main factors affecting survival [1-3]. Here we present a novel technique of stripping the peritoneal surfaces as a part of cytoreductive surgery in such cases. A 55year-old woman diagnosed with peritoneal carcinomatosis was considered appropriate for primary cytoreduction after assessment of her thorax-abdominopelvic tomography, which revealed resectable intra-abdominal disease. Upon laparotomy, omental cake adherent to pelvis-filling mass, disseminated implants on the diaphragm, meso of the descending colon and small intestine were observed. The mass invaded the rectosigmoid colon, uterus, adnexa and the bladder resulting in frozen pelvis. Palpable retroperitoneal pelvic and para-aortic lymph nodes were detected. On the other side, stomach, anti-mesenteric surfaces and mesentery root of the small bowel were tumor-free. Hence, upon these perioperative and preoperative imaging findings, complete cytoreduction was thought to be achievable. Therefore, primary cytoreduction was performed. Total omentectomy, hysterectomy with bilateral salpingo-oophorectomy, rectosigmoid low anterior resection and retroperitoneal lymphadenectomy were performed. With the assistance of an injector needle connected to the insufflator tube (as in laparoscopic surgery), carbon dioxide gas was blown into the right retroperitoneal area and subsequently peritoneum was rapidly stripped up to the right diaphragm. The same procedure was then applied to the diaphragm and meso of the bowels, respectively. Owing to this technique, total stripping of all involved peritoneal surfaces was clearly facilitated and R0 goal was reached. Gas insufflation caused convenient detachment of the peritoneal surfaces along their anatomical line which led to concluding the stripping procedures easily, rapidly and safely without bleeding. Thus, according to our experience, about 10 to 15min per procedure are saved in such cases. Potential complications of CO 2 gas used here are not superior to those in transperitoneal or retroperitoneal laparoscopic procedures. During the operation, patient was followed-up for potential complications such as subcutaneous emphysema and CO 2 gas embolism.Thus, hourly blood gas was monitored. Another potential complication is injury of the vessels while inserting the needle which can be avoided by cautious inserting under the peritoneal surfaces superficially and using transillumination. In case such injuries happen, tamponing is a sufficient measure. In our serial, no perioperative complications belonging to this technique were encountered. However, long term outcomes such as precise time difference, difference in blood loss, complication rates, adhesions, morbidity associated with this technique and its impact on survival of the patients with advanced ovarian cancer have yet to be investigated. Therefore, a prospective study to validate this technique's long-term usefulness has been initiated in our clinic. We believe that this practical and effective technique will offer significant improvements in efforts to achieve complete cytoreduction. Copyright © 2017 Elsevier Inc. All rights reserved.

Optimal cytoreduction is one the main factors improving survival outcomes in patients affected by ovarian cancer (OC). It is estimated that approximately 40% of OC patients have gross disease located on the diaphragm. However, no mature data evaluating outcomes of surgical techniques for the management of diaphragmatic carcinosis exist. In the present study, we aimed to estimate surgery-related morbidity of different surgical techniques for diaphragmatic cytoreduction in advanced or recurrent OC. PubMed (MEDLINE), Web of Science, and Clincaltrials.gov databases were searched for records estimating outcomes of diaphragmatic peritoneal stripping (DPS) or diaphragmatic full-thickness resection (DFTR) for OC. The meta-analysis was performed using the Cochrane Review software. For the final analysis, 5 articles were available, including 272 patients. Diaphragmatic peritoneal stripping and DFTR were performed in 197 patients (72%) and 75 patients (28%), respectively. Pooled analysis suggested that the estimated pleural effusion rate was 43% and 51% after DPS and DFTR, respectively. The need for pleural punctures or chest tube placement was 4% and 9% after DPS and DFTR, respectively. The rate of postoperative pneumothorax (4% vs 9%; odds ratio, 0.31; 95% confidence interval, 0.05-2.08) and subdiaphragmatic abscess (3% vs 3%; odds ratio, 0.45; 95% confidence interval, 0.09-2.31) were similar after the execution of DPS and DFTR. Diaphragmatic surgery is a crucial step during cytoreduction for advanced or recurrent OC. Obviously, the choice to perform DPS or DFTR depends on the infiltration of the diaphragmatic muscle or not. Both the procedures are associated with a low pulmonary complication and chest tube placement rates.

Peritoneal spread from colorectal cancer is second only to the liver as a site for metastasis. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is a well-established treatment option for patients with peritoneal carcinomatosis (PC) of colorectal origin. However, due to concerns regarding both its clinical benefit and high cost, its universal adoption as the standard of care for patients with limited peritoneal dissemination has been slow. The purpose of this review was to clarify the clinical utility and cost effectiveness of CRS-HIPEC in the treatment of colorectal PC using the framework of value-based medicine, which attempts to combine both benefit and cost into a single quantifiable metric. Our comprehensive review of the clinical outcomes and cost effectiveness of CRS-HIPEC demonstrate that it is a highly valuable oncologic therapy and a good use of healthcare resources.

Cytoreductive nephrectomy vs medical therapy as initial treatment: a rational approach to the sequence question in metastatic renal cell carcinoma.

Renal cell carcinoma (RCC) can be considered as two distinct entities: localized and metastatic disease. We conducted a review of the scientific literature published within the past decade pertaining to cytoreductive nephrectomy for metastatic RCC. Retrospective data and historical prospective series have demonstrated the survival benefit of debulking nephrectomy in well-selected RCC patients. New medical therapies, including vascular endothelial growth factor and mTOR pathway blocking drugs, are active biological agents, with survival improvement and potential regression of metastatic and primary tumors. Our current therapeutic challenge is the optimal integration of multimodal therapy consisting of systemic therapy and surgery including cytoreductive nephrectomy, debulking, and metastasectomy. Empiric data to guide this decision are limited. The decision concerning whether medical or surgical therapy should be the primary treatment approach selected must be made on an individual basis, taking into account patient performance status, clinical parameters, and physician expertise and recommendations, thus making each case a unique therapeutic challenge.

Prognosis in women with ovarian cancer mainly depends on International Federation of Gynecology and Obstetrics stage and the ability to perform optimal cytoreductive surgery. Since ovarian cancer has a heterogeneous presentation and clinical course, predicting progression-free survival (PFS) and overall survival (OS) in the individual patient is difficult. The objective of this study was to determine predictors of PFS and OS in women with advanced stage epithelial ovarian cancer (EOC) after primary cytoreductive surgery and first-line platinum-based chemotherapy. Retrospective observational study. Two teaching hospitals and one university hospital in the south-western part of the Netherlands. Women with advanced stage EOC. All women who underwent primary cytoreductive surgery for advanced stage EOC followed by first-line platinum-based chemotherapy between January 1998 and October 2004 were identified. To investigate independent predictors of PFS and OS, a Cox' proportional hazard model was used. Nomograms were generated with the identified predictive parameters. The primary outcome measure was OS and the secondary outcome measures were response and PFS. A total of 118 women entered the study protocol. Median PFS and OS were 15 and 44 months, respectively. Preoperative platelet count (P = 0.007), and residual disease <1 cm (P = 0.004) predicted PFS with a optimism corrected c-statistic of 0.63. Predictive parameters for OS were preoperative haemoglobin serum concentration (P = 0.012), preoperative platelet counts (P = 0.031) and residual disease <1 cm (P = 0.028) with a optimism corrected c-statistic of 0.67. PFS could be predicted by postoperative residual disease and preoperative platelet counts, whereas residual disease, preoperative platelet counts and preoperative haemoglobin serum concentration were predictive for OS. The proposed nomograms need to be externally validated.

Ovarian cancer (OC) ranks fifth in mortality among females cancer patients. Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) have radically changed the treatment of OC. The aim of this study was to evaluate overall survival (OS) and disease-free survival (DFS) in our patient population after the application of combined CRS and HIPEC treatment. The study included patients who met defined inclusion and exclusion criteria and had undergone CRS of peritoneal carcinomatosis from 2006 to 2011. Tumor extension was intraoperatively calculated using peritoneal cancer index (PCI). After CRS had been performed, selected patients underwent closed HIPEC. Assessment of successful surgery was estimated with the completeness of cytoreduction score. The study involved 31 patients. The median DFS was 19 months. The DFS for 1 and 2-year period were 69.2 and 35.2%, respectively. The mean OS was 51 months. The 1-, 2- and 5-year OS was 85.4, 63.3 and 56.3%, respectively. PCI ranged from 1 to 24 and the majority (77.4%) of the patients had PCI score below 13. The most frequent carcinomatosis was observed in the omentum (80.6%), followed by adnexae (61.3%), uterus (58.1%), colon (58.1%). spleen (25.8%), diaphragm (25.8%), small intestine (19.4%), bursa omentalis 19.4, liver (9.7%), and pancreas (3.2%). The results of the current study are in concordance with the literature which clearly favors combined the CRS and HIPEC treatment. The reported data suggest that this method could be successfully applied in our region and outline the necessity of future multicentric studies that will involve major regional hospitals.

This study describes the outcomes of patients with colorectal peritoneal carcinomatosis (PC) with or without liver metastases (LMs) after curative surgery combined with hyperthermic intraperitoneal chemotherapy, in order to assess prognostic factors. Cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) increases overall survival (OS) in patients with PC. The optimal treatment both for PC and for LMs within one surgical operation remains controversial. Patients with PC who underwent CRS followed by HIPEC were evaluated from a prospective database. Overall survival and disease free survival (DFS) rates in patients with PC and with or without LMs were compared. Univariate and multivariate analyses were performed to evaluate predictive variables for survival. From 1999 to 2011, 22 patients with PC and synchronous LMs (PCLM group), were compared to 36 patients with PC alone (PC group). No significant difference was found between the two groups. The median OS were 36 months [range, 20-113] for the PCLM group and 25 months [14-82] for the PC group (p > 0.05) with 5-year OS rates of 38% and 40% respectively (p > 0.05). The median DFS were 9 months [9-20] and 11.8 months [6.5-23] respectively (p = 0.04). The grade III-IV morbidity and cytoreduction score (CCS) >0 (p < 0.05) were identified as independent factors for poor OS. Resections of LMs and CCS >0 impair significantly DFS. Synchronous complete CRS of PC and LMs from a colorectal origin plus HIPEC is a feasible therapeutic option. The improvement in OS is similar to that provided for patients with PC alone.

Surgical cytoreduction has been postulated to affect survival by increasing the efficacy of chemotherapy in ovarian cancer. We hypothesized that women with high-grade serous ovarian cancer, which usually responds to chemotherapy, would derive greater benefit from complete cytoreduction than those with histologic subtypes that are less responsive to chemotherapy, such as mucinous and clear cell carcinoma. We conducted a retrospective cohort study of patients who underwent primary cytoreductive surgery and adjuvant chemotherapy for stage IIIC or IV epithelial ovarian cancer from 2011 to 2013 using data from the National Cancer Database. We constructed multivariable models to quantify the magnitude of associations between residual disease status (no residual disease, ≤1cm, or >1cm) and all-cause mortality by histologic type among women with clear cell, mucinous, and high-grade serous ovarian cancer. Because 26% of the sample had unknown residual disease status, we used multiple imputations in the primary analysis. We identified 6,013 women with stage IIIC and IV high-grade serous, 307 with clear cell, and 140 with mucinous histology. The association between residual disease status and mortality hazard did not differ significantly among histologic subtypes of ovarian cancer (p for interaction=0.32). In covariate adjusted models, compared to suboptimal cytoreduction, cytoreduction to no gross disease was associated with a hazard reduction of 42% in high-grade serous carcinoma (hazard ratio [HR]=0.58, 95% confidence interval [CI]=0.49-0.68), 61% in clear cell carcinoma (HR=0.39, 95% CI=0.22-0.69), and 54% in mucinous carcinoma (HR=0.46, 95% CI=0.22-0.99). We found no evidence that surgical cytoreduction was of greater prognostic importance in high-grade serous carcinomas than in histologies that are less responsive to chemotherapy.

The aim of this retrospective study is to analyze the prognostic role and the practical implication of mesenteric lymph nodes (MLN) involvements in advanced ovarian cancer (AOC). A total of 429 patients with AOC underwent surgery between December 2007 and May 2017. We included in the study 83 patients who had primary (PDS) or interval debulking surgery (IDS) for AOC with bowel resection. Numbers, characteristics and surgical implication of MLN involvement were considered. Eighty-three patients were submitted to bowel resection during cytoreduction for AOC. Sixty-seven patients (80.7%) underwent primary debulking surgery (PDS). Sixteen patients (19.3%) experienced interval debulking surgery (IDS). 43 cases (51.8%) showed MLN involvement. A statistic correlation between positive MLN and pelvic lymph nodes (PLN) (p = 0.084), aortic lymph nodes (ALN) (p = 0.008) and bowel infiltration deeper than serosa (p = 0.043) was found. A longer overall survival (OS) and disease-free survival was observed in case of negative MLN in the first 20 months of follow-up. No statistical differences between positive and negative MLN in terms of operative complication, morbidity, Ca-125, type of surgery (radical vs supra-radical), length and site of bowel resection, residual disease and site of recurrence were observed. An important correlation between positive MLN, ALN and PLN was detected; these results suggest a lymphatic spread of epithelial AOC similar to that of primary bowel cancer. The absence of residual disease after surgery is an independent prognostic factor; to achieve this result should be recommended a radical bowel resection during debulking surgery for AOC with bowel involvement.

Non-thermal irreversible electroporation (N-TIRE) has shown promise as an ablative therapy for a variety of soft-tissue neoplasms. Here we describe the therapeutic planning aspects and first clinical application of N-TIRE for the treatment of an inoperable, spontaneous malignant intracranial glioma in a canine patient. The N-TIRE ablation was performed safely, effectively reduced the tumor volume and associated intracranial hypertension, and provided sufficient improvement in neurological function of the patient to safely undergo adjunctive fractionated radiotherapy (RT) according to current standards of care. Complete remission was achieved based on serial magnetic resonance imaging examinations of the brain, although progressive radiation encephalopathy resulted in the death of the dog 149 days after N-TIRE therapy. The length of survival of this patient was comparable to dogs with intracranial tumors treated via standard excisional surgery and adjunctive fractionated external beam RT. Our results illustrate the potential benefits of N-TIRE for in vivo ablation of undesirable brain tissue, especially when traditional methods of cytoreductive surgery are not possible or ideal, and highlight the potential radiosensitizing effects of N-TIRE on the brain.

High-grade (HG) mucinous appendiceal neoplasms (MAN) have a worse prognosis than low-grade histology. Our objective was to assess the safety and efficacy of cytoreductive surgery with hyperthermic intraperitoneal chemoperfusion (CRS/HIPEC) in patients with high-grade, high-volume (HG-HV) peritoneal metastases in whom the utility of this aggressive approach is controversial. Prospectively collected perioperative data were compared between patients with peritoneal metastases from HG-HV MAN, defined as simplified peritoneal cancer index (SPCI) ≥12, and those with high-grade, low-volume (HG-LV; SPCI <12) disease. Kaplan-Meier curves and multivariate Cox regression models identified prognostic factors affecting oncologic outcomes. Overall, 54 patients with HG-HV and 43 with HG-LV peritoneal metastases underwent CRS/HIPEC. The HG-HV group had longer operative time, increased blood loss/transfusion, and increased intensive care unit length of stay (p < 0.05). Incomplete macroscopic cytoreduction (CC-1/2/3) was higher in the HG-HV group compared with the HG-LV group (68.5 vs. 32.6 %; p = 0.005). Patients with HG-HV disease demonstrated worse survival than those with HG-LV disease (overall survival [OS] 17 vs. 42 m, p = 0.009; time to progression (TTP) 10 vs. 14 m, p = 0.024). However, when complete macroscopic resection (CC-0) was achieved, the OS and progression-free survival of patients with HG-HV disease were comparable with HG-LV disease (OS 56 vs. 52 m, p = 0.728; TTP 20 vs. 19 m, p = 0.393). In a multivariate Cox proportional hazard regression model, CC-0 resection was the only significant predictor of improved survival for patients with HG-HV disease. Although patients with HG-HV peritoneal metastases from MAN have worse prognosis compared with patients with HG-LV disease, their survival is comparable when complete macroscopic cytoreduction is achieved.

[Quality control criteria in the surgical management of advanced ovarian cancers].

Two concurrent policies can be proposed to improve the quality of care for ovarian cancer surgery: organization of care, audit. The two policies are not to be opposed: the efficacy of any policy must be audited, targets are more rapidly reached and more easily audited when an underlying organization is available. However, the arbitrary definition of criteria is a challenge. The interpretation of results depends on the context of each individual center. There is a definite risk of unwanted effects: competition to reach the cut-off if quantitative caseload criteria are demanded, reduction of the quality of cytoreduction if the complication rate is included, selection of patients if the rate of complete cytoreduction is chosen as a major parameter. Quality control must encompass the standard of preoperative workup, the quality of operative report, the complication rate and the oncological outcome. Although quantitative yearly caseload requirements may contribute to the quality of care, it seems more pertinent to recall the prerequisites that the surgeon must fulfil before undertaking a surgery for ovarian cancer. Knowledge of the specific features of the disease and of all the components of its medical management, skills in general surgical procedures required to complete staging and cytoreduction, and contribution to a multidisciplinary team involved in clinical research are mandatory. Even though no definitive proof is available, the available information tend to show a superiority of the standard of surgical care provided by experienced or specialized surgeons.

This study assesses the value of using Intraoperative Near Infrared Fluorescence Imaging and Indocyanine green to detect colorectal carcinomatosis during oncological surgery. In colorectal carcinomatosis cancer, two of the most important prognostic factors are completeness of staging and completeness of cytoreductive surgery. Presently, intraoperative assessment of tumoral margins relies on palpation and visual inspection. The recent introduction of Near Infrared fluorescence image guidance provides new opportunities for surgical roles, particularly in cancer surgery. The study was a non-randomized, monocentric, pilot "ex vivo" blinded clinical trial validated by the ethical committee of University Hospital of Saint Etienne. Ten patients with colorectal carcinomatosis cancer scheduled for cytoreductive surgery were included. Patients received 0.25 mg/kg of Indocyanine green intravenously 24 h before surgery. A Near Infrared camera was used to detect "ex-vivo" fluorescent lesions. There was no surgical mortality. Each analysis was done blindly. In a total of 88 lesions analyzed, 58 were classified by a pathologist as cancerous and 30 as non-cancerous. Among the 58 cancerous lesions, 42 were correctly classified by the Intraoperative Near-Infrared camera (sensitivity of 72.4%). Among the 30 non-cancerous lesions, 18 were correctly classified by the Intraoperative Near-Infrared camera (specificity of 60.0%). Near Infrared fluorescence imaging is a promising technique for intraoperative tumor identification. It could help the surgeon to determine resection margins and reduce the risk of locoregional recurrence.

2017-01-01

Most cases with advanced-stage epithelial ovarian malignancies will experience recurrent disease at a certain moment of their evolution, even if maximal cytoreductive surgery has been performed at the moment of initial diagnosis. However, it seems that the best therapeutic strategy, in case of relapse, remains aggressive re-resection, with complete cytoreduction being the most efficient way to improve survival. We present the case of a 55-year-old patient diagnosed with an isolated pelvic recurrence after stage IIIC surgically-treated ovarian cancer three years after primary cytoreduction. Intraoperatively, the diagnosis of an isolated pelvic recurrence invading the urinary bladder was confirmed. The recurrent tumor was resected en bloc with partial cystectomy. The postoperative course was uneventful, while histopathological studies confirmed the presence of a poorly differentiated epithelial ovarian recurrent adenocarcinoma. At two year follow-up, the patient is free of any recurrent disease. Isolated pelvic recurrences after surgically-treated ovarian adenocarcinomas can be safely removed and might improve survival.

To describe our experience with cisplatin- and paclitaxel-based IP chemotherapy in patients treated initially with either neoadjuvant chemotherapy and interval debulking surgery (IDS) or primary cytoreductive surgery (PCRS). We performed a retrospective review of the records of 67 patients (38 IDS, 29 PCRS) enrolled in the intraperitoneal (IP) chemotherapy program at the Tom Baker Cancer Centre between 2006 and 2009. Information pertaining to patient demographics, IP chemotherapy toxicity, and catheter complications was extracted, and the median time to recurrence was calculated. Most patients in the study were aged 50 to 70 years and had a diagnosis of stage III serous ovarian cancer. Overall, 295/393 IP cycles (75%) were successfully administered. The proportion of patients completing six cycles of chemotherapy in the IDS and PCRS groups was 53% and 59%, respectively. Frequent (> 25%) Grade 1 to 2 chemotherapy toxicities included fatigue, peripheral neuropathy, and nausea. Catheter complications were observed in 34% of patients (23/67). The recurrence rates for patients completing four or more cycles of IP chemotherapy in the IDS and PCRS groups were 58% and 35%, respectively, with the median time to recurrence approximately one year. Although IP chemotherapy is well tolerated in both IDS and PCRS patients, the median time to recurrence is shorter than expected.

The majority of advanced ovarian cancer patients have peritoneal carcinomatosis involving from the pelvis to upper abdomen, which is a major obstacle to optimal cytoreduction. Since total parietal peritonectomy was introduced for treating peritoneal carcinomatosis from colorectal cancer [3], similar surgical techniques including pelvic peritonectomy have been applied in advanced ovarian cancer with peritoneal carcinomatosis [1], and these can increase the rate of complete cytoreduction up to 60% [2]. However, there are few reports on total parietal peritonectomy for ovarian cancer patients. In this surgical film, we showed total parietal peritonectomy with en bloc pelvic resection for treating advanced ovarian cancer with peritoneal carcinomatosis. A 43years-old woman was diagnosed with high-grade serous carcinoma of the ovary after right adnexectomy. Computed tomography demonstrated subdiaphragmatic involvements, omental cake, lymph node metastases and huge pelvic mass infiltrating the uterus, cul-de-sac, and pelvic peritoneum. Primary debulking surgery was considered because of a high likelihood for complete cytoreduction. First, the whole abdomen and pelvis were adequately exposed and the visceral organs thoroughly mobilized. Then, the parietal peritoneum was dissected from the subdiaphragmatic, paracolic and pelvic areas. Tumor-infiltrated visceral organs such as the uterus, adnexae, rectosigmoid colon and cul-de-sac were resected en bloc with the parietal peritoneum (Fig. 1). Total parietal peritonecotmy with en bloc pelvic resection is a feasible procedure for removing peritoneal metastasis in advanced ovarian cancer patients, which contributes to optimal cytoreduction improving prognosis.

Locoregional spread of abdominopelvic malignant tumors frequently results in peritoneal carcinomatosis (PC). The prognosis of PC patients treated by conventional systemic chemotherapy is poor, with a median survival of < 6 mo. However, over the past three decades, an integrated treatment strategy of cytoreductive surgery (CRS) + hyperthermic intraperitoneal chemotherapy (HIPEC) has been developed by the pioneering oncologists, with proved efficacy and safety in selected patients. Supported by several lines of clinical evidence from phases I, II and III clinical trials, CRS + HIPEC has been regarded as the standard treatment for selected patients with PC in many established cancer centers worldwide. In China, an expert consensus on CRS + HIPEC has been reached by the leading surgical and medical oncologists, under the framework of the China Anti-Cancer Association. This expert consensus has summarized the progress in PC clinical studies and systematically evaluated the CRS + HIPEC procedures in China as well as across the world, so as to lay the foundation for formulating PC treatment guidelines specific to the national conditions of China.

Residual disease (RD) after primary debulking surgery (PDS) is one of the main factors driving ovarian cancer prognosis. The primary end point of this study was assessment of the impact that surgery had on survival outcomes for patients with advanced ovarian cancer. Data on the effect of newly diagnosed advanced-stage ovarian, tubal, and peritoneal cancers were analyzed during two study periods (T1: 2001-2006 and T2: 2007-2012), in which the concepts of optimal and complete cytoreduction were introduced and implemented. In this study, 260 patients (36%) had surgery during T1 and 462 patients (64%) had surgery during T2. The rate of PDS increased, from 55.4% (144/260) during T1 to 85.5% (395/462) during T2 (p < 0.001). At the time of PDS, complete resection (RD0) was achieved for 45.1% of the patients during T1 and 76.7% of the patients during T2 (p < 0.001), whereas optimal resection (RD < 1 cm) was achieved for 60.4% of the patients during T1 and 85.3% of the patients during T2 (p < 0.001). Disease-free survival improved during the study periods (p = 0.006). Overall survival was similar in T1 and T2 (p = 0.18). The preoperative CA125 level, disease stage, and RD remained independently associated with disease-free survival (p ≤ 0.05). The performance of interval debulking surgery (IDS) instead of PDS correlated with worse survival outcomes (hazard ratio [HR] 1.47; 95% confidence interval [CI] 1.24-1.92; p = 0.02), whereas achievement of RD0 and RD < 1 cm independently improved overall survival (HR 0.45; 95% CI 0.22-0.91; p = 0.02 for RD0 and HR 0.47; 95% CI 0.23-0.96; p = 0.03 for RD0). The implementation of extensive cytoreduction allows improvement of patient outcomes. Further studies are needed to assess the risk-to-benefit ratio between PDS and IDS and to identify patients who benefit much more from one treatment method than from another.

Background Urinary tract involvement in patients with peritoneal surface disease treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) often requires complex urologic resections and reconstruction to achieve optimal cytoreduction. The impact of these combined procedures on surgical outcomes is not well defined. Methods A prospective database of CRS/HIPEC procedures was analyzed retrospectively. Type of malignancy, performance status, resection status, hospital and intensive care unit stay, morbidity, mortality, and overall survival were reviewed. Results A total of 864 patients underwent 933 CRS/HI-PEC procedures, while 64 % (550) had preoperative ureteral stent placement. A total of 7.3 % had an additional urologic procedure without an increase in 30-day (p = 0.4) or 90-day (p = 1.0) mortality. Urologic procedures correlated with increased length of operating time (p < 0.001), blood loss (p < 0.001), and length of hospitalization (p = 0.003), yet were not associated with increased overall 30-day major morbidity (grade III/IV, p = 0.14). In multivariate analysis, independent predictors of additional urologic procedures were prior surgical score (p < 0.001), number of resected organs (p = 0.001), and low anterior resection (p = 0.03). Long-term survival was not statistically different between patients with and without urologic resection for low-grade appendiceal primary lesions (p = 0.23), high-grade appendiceal primary lesions (p = 0.40), or colorectal primary lesions (p = 0.14). Conclusions Urinary tract involvement in patients with peritoneal surface disease does not increase overall surgical morbidity. Patients with urologic procedures demonstrate survival patterns with meaningful prolongation of life. Urologic involvement should not be considered a contraindication for CRS/HIPEC in patients with resectable peritoneal surface disease. PMID:24217789

Peritoneal carcinomatosis is an increasingly common finding in gastric carcinoma. Previously, patients were treated as terminal, and median survival was poor. The use of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in this context is still highly debatable. The aim of this study was to evaluate the long-term outcomes associated with CRS and HIPEC, and define prognostic factors for cure, if possible. All patients with gastric carcinomatosis from five French institutions who underwent combined complete CRS and HIPEC and had a minimum follow-up of 5 years were included in this study. Cure was defined as a disease-free interval of more than 5 years from the last treatment until the last follow-up. Of the 81 patients who underwent CRS and HIPEC from 1989 to 2009, 59 had a completeness of cytoreduction score (CCS) of 0 (complete macroscopic resection), and the median Peritoneal Cancer Index (PCI) score was 6. Mitomycin C was the most commonly used drug during HIPEC (88 %). The 5-year overall survival (OS) rate was 18 %, with nine patients still disease-free at 5 years, for a cure rate of 11 %. All 'cured' patients had a PCI score below 7 and a CCS of 0. Factors associated with improved OS on multivariate analysis were synchronous resection (p = 0.02), a lower PCI score (p = 0.12), and the CCS (p = 0.09). The cure rate of 11 % for patients with gastric carcinomatosis who are deemed terminal emphasizes that CRS and HIPEC should be considered in highly selected patients (low disease extent and complete CRS).

The multi-institutional registry in this study evaluated the outcome after cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) for patients with peritoneal metastases (PM) from small bowel adenocarcinoma (SBA). A multi-institutional data registry including 152 patients with PM from SBA was established. The primary end point was overall survival (OS) after CRS plus HIPEC. Between 1989 and 2016, 152 patients from 21 institutions received a treatment of CRS plus HIPEC. The median follow-up period was 20 months (range 1-100 months). Of the 152 patients, 70 (46.1%) were women with a median age of 54 years. The median peritoneal cancer index (PCI) was 10 (mean 12; range 1-33). Completeness of cytoreduction (CCR) 0 or 1 was achieved for 134 patients (88.2%). After CRS and HIPEC, the median OS was 32 months (range 1-100 months), with survival rates of 83.2% at 1 year, 46.4% at 3 years, and 30.8% at 5 years. The median disease-free survival after CCR 0/1 was 14 months (range 1-100 months). The treatment-related mortality rate was 2%, and 29 patients (19.1%) experienced grades 3 or 4 operative complications. The period between detection of PM and CRS plus HIPEC was 6 months or less (P = 0.008), and multivariate analysis identified absence of lymph node metastasis (P = 0.037), well-differentiated tumor (P = 0.028), and PCI of 15 or lower (P = 0.003) as independently associated with improved OS. The combined treatment strategy of CRS plus HIPEC achieved prolonged survival for selected patients who had PM from SBA with acceptable morbidity and mortality.

Neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) may be a valuable treatment option in advanced ovarian cancer when primary cytoreduction is not feasible. However, a consensus on the ideal number of NACT cycles is still lacking. In the present investigation, we aimed to evaluate how number of cycles of NACT influenced patients' outcomes. Data of consecutive patients undergoing NACT and IDS were retrospectively reviewed in 4 Italian centers, and survival outcomes were evaluated. Overall, 193 patients were included. Cycles of NACT were 3, 4, and at least 5 in 77 (40%), 74 (38%), and 43 (22%) patients, respectively. Patients undergoing 3 cycles experienced a similar disease-free survival (hazard ratio [HR], 1.12; 95% confidence interval [CI], 0.89-1.65; P = 0.20) but an improved overall survival (HR, 1.64; 95% CI, 1.05-2.4; P = 0.02) in comparison to patients receiving at least 4 cycles. Five-year overall survival was 46% and 31% for patients having 3 and at least 4 cycles. Ten-year overall survival was 26% and 18% for patients having 3 and at least 4 cycles (HR, 1.70; 95% CI, 1.13-2.55; P = 0.009). Using multivariate analysis, we observed that only Eastern Cooperative Oncology Group performance status correlated with overall survival (HR, 1.76; 95% CI, 1.2-2.49; P = 0.001). In addition, a trend toward worse overall survival was observed for patients with residual disease at IDS (HR, 1.29; 95% CI, 0.98-1.70; P = 0.06) and patients receiving at least 4 cycles (HR, 1.76; 95% CI, 0.95-3.22; P = 0.06). Our data underline the potential implication of number of cycles of NACT before IDS. Further prospective studies are warranted to assess this correlation.

We investigated the risk factors, incidence, and role of thromboprophylaxis in the development of thrombosis following cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). We reviewed data of patients with CRS/HIPEC in three hospitals. Overall, 192 patients underwent CRS/HIPEC during 2007-2016. Mechanical (thigh-length pneumatic compression stockings) and pharmacologic thromboprophylaxis (40 mg enoxaparin daily, starting 12 h before surgery until discharge) was provided for all patients; and 116 (60.4%) also received an extended course of enoxaparin for 2-4 weeks after discharge. Twenty-six patients experienced thrombotic complications (13.5%) including portal-splenic-mesenteric venous thrombosis (n = 11, 5.7%), pulmonary embolism (n = 10, 5.2%), and deep vein thrombosis (n = 5, 2.6%); most (n = 21, 80.8%) occurred after hospital discharge. Univariate analysis identified Peritoneal Cancer Index, intraoperative transfusion requirement, operative blood loss, operative time, lengths of hospital, and intensive care unit stay, and lack of administration of anticoagulation at discharge as significantly associated with thrombosis. With multivariate analysis, only the lack of anticoagulation therapy at discharge remained significantly associated with thrombosis (P = 0.0001). Thromboembolic complications are common following CRS/HIPEC. As significantly lower rates of thrombosis were found in patients who received an extended course of anticoagulation, we support its use for at least 2 weeks after discharge. © 2017 Wiley Periodicals, Inc.

Objective To analyze the postoperative recurrence of renal cell carcinoma associated with Xp11.2 translocation/TFE3 gene fusion (Xp11.2 tRCC). Methods This retrospective study was approved by the institutional review board and performed in accordance with the ethical standards established by the institution. Demographic, clinical, pathological, and follow-up data were compiled for the study cohort. Results During a mean follow-up of 41.3 months (range, 3-104 months), 8 of 34 patients with Xp11.2 tRCC were confirmed to have recurrence. Three of these patients died with poor outcomes due to a vena cava tumor embolus, and one died of distant metastasis 48 months after the initial nephrectomy during which lymph node metastasis was found. Three patients survived after cytoreduction surgery. One patient was diagnosed with lung metastasis 11 months postoperatively. Conclusions The TNM classification provides significant prognostic information for Xp11.2 tRCC. A relatively active surveillance algorithm is recommended, and cytoreduction surgery is an effective approach for recurrent Xp11.2 tRCC. Larger studies are required to more extensively investigate the recurrence of these potentially aggressive tumors.

To determine the effect of disseminated cancer on perioperative outcomes following radical nephrectomy. We conducted a retrospective cohort study of patients undergoing radical nephrectomy for kidney cancer from 2005 to 2014 using the American College of Surgeons National Surgical Quality Improvement Program, a multi-institutional prospective registry that captures perioperative surgical complications. Patients were stratified according to the presence (n = 657) or absence (n = 7143) of disseminated cancer at the time of surgery. We examined major complications (death, reoperation, cardiac event, or neurologic event) within 30 days of surgery. Secondary outcomes included pulmonary, infectious, venous thromboembolic, and bleeding complications; prolonged length of stay; and concomitant procedures (bowel, liver, spleen, pancreas, and vascular procedures). Adjusted odds ratio (aOR) and 95% confidence interval (95% CI) were calculated using multivariate logical regression models. Patients with disseminated cancer were older and more likely to be male, have greater comorbidities, and have undergone open surgery. Major complications were more common among patients with disseminated cancer (7.8%) than those without disseminated cancer (3.2%; aOR 2.01, 95% CI 1.46-2.86). Mortality was significantly higher in patients with disseminated cancer (3.2%) than those without disseminated cancer (0.5%; P < .0001). Pulmonary (aOR 1.68, 95% CI 1.09-2.59), thromboembolic (aOR 1.72, 95% CI 1.01-2.96), and bleeding complications (aOR 2.12, 95% CI 1.73-2.60) were more common among patients with disseminated cancer as was prolonged length of stay (aOR 1.27, 95% CI 1.06-1.53). Nephrectomy in patients with disseminated cancer is a morbid operation with significant perioperative mortality. These data may be used for preoperative counseling of patients undergoing cytoreductive nephrectomy. Copyright © 2016 Elsevier Inc. All rights reserved.

Background Postoperative pancreatic fistulas (POPFs) are potentially morbid complications that often require therapeutic interventions. Distal pancreatectomy performed during cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemoperfusion (HIPEC) puts patients at risk for POPF. The authors hypothesized that POPFs are more severe after CRS/HIPEC than after pancreatectomy alone. Methods Clinicopathologic and perioperative details, including POPF by International Study Group of Pancreatic Fistula criteria (ISGPF), and oncologic outcomes for patients undergoing distal pancreatectomy during CRS/HIPEC for peritoneal carcinomatosis of appendiceal (n = 31) or colorectal (n = 23) origin (HIPEC group) were compared with those for patients undergoing minimally invasive or open distal pancreatectomy without HIPEC (n = 66) for locally resectable pancreatic adenocarcinoma (non-HIPEC group). Results The incidence of POPF was similar between the HIPEC and non-HIPEC groups (26 %). The severity of POPF according to the ISGPF criteria was significantly worse in the HIPEC group. The HIPEC patients had 13 grade B fistulas and 1 grade C fistula compared with 12 grade A fistulas and 4 grade B fistulas in the non-HIPEC group. The HIPEC patients with POPF did not differ in the extent of their CRS, peritoneal cancer index, length of hospital stay, or other postoperative complications from the the HIPEC patients without POPF. The HIPEC patients with colorectal carcinomatosis who experienced POPF had higher disease recurrence in the first year after CRS/HIPEC than those without POPF. Conclusion The findings showed that POPFs are more severe when distal pancreatectomy is combined with CRS/HIPEC. Moreover, selective use of distal pancreatectomy is important during CRS/HIPEC because POPFs may increase early disease recurrence for patients with colorectal carcinomatosis. PMID:25348781

Worldwide, cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has been used for nearly 3 decades to treat peritoneal metastases (PM), improve quality of life, and prolong survival substantially in selected patients. In India, the use of the combined modality of treatment dates back a decade with majority of the efforts taking place within the last 5 years. The first PSOGI workshop (India) held in April 2015, at Bangalore, India offered an opportunity for Indian surgeons performing CRS and HIPEC to share their experience. To study the methodologies of CRS and HIPEC (hospital set up, equipment, training and surgical background) as well as the outcomes in terms of perioperative morbidity and mortality and short and long term survival of patients treated in India, Indian surgeons who had treated at least 10 patients with this combined modality were invited to present their experience. Data collection was retrospective. Analysis of the pooled data was carried out. Eight surgeons treated 384 patients with CRS and HIPEC over a period of 10 years. The commonest primary sites were ovary (as first line therapy n = 124), followed by appendix, including pseudomyxoma peritonei (n = 99), colorectum (n = 77), recurrent ovary (as second line therapy, n = 33), stomach (n = 15), primary peritoneal cancer (n = 10), peritoneal mesothelioma (n = 9) and rare tumors in 17 patients. The weighted mean PCI for all 384 patients was 18.25. 349/384 patients (90.88 %) had a complete cytoreduction (completeness of cytoreduction score of CC-0/1). Grade 3-5 complications developed in 108 patients (27.34 %) and 30 day mortality occurred in 28 (7.29 %) patients. This study showed that CRS and HIPEC can be performed with an acceptable morbidity and mortality in Indian patients. Most of the surgeons are on the learning curve and further improvement in these outcomes is expected over a period of time. Pooling of data related to both common and rare peritoneal cancers would be useful in knowing the disease behavior, response to treatment and outcomes in Indian patients. The 2015 PSOGI meeting provided a unique platform for data presentation with feedback from international experts in the field of peritoneal surface oncology. Future meetings are planned to expand the evaluation of Indian data and progress.

Endometrial carcinoma is the most common gynecologic malignancy worldwide. Prognosis of patients with peritoneal carcinomatosis (PC) from endometrial carcinoma is deadly, with an estimated median survival not exceeding 12 months. The objective of this study was to report our experience with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for managing PC from primary and recurrent endometrial carcinoma. A retrospective analysis of 6 patients with PC arising from endometrial cancer, who were managed with CRS and HIPEC at our referral tertiary care center, from November 2010 to August 2013. Six patients underwent CRS and HIPEC. CRS was performed using standard peritonectomy procedures and visceral resections directed toward the complete elimination of tumors from ab.dominopelvic cavity. HIPEC was performed with cisplatin (50 mg/m2) and doxorubicin (15 mg/m2) and allowed to circulate in abdominopelvic cavity for 90 minutes at 41.0 to 42.2°C. Two patients with primary endometrial carcinoma and 4 patients with recurrent endometrial carcino.ma confined to peritoneal cavity were studied. Complete cytoreduction (CC-0) was achieved in 5 patients. The International Federation of Gynecology and Obstetrics (FIGO) stages and histopathological types were as follows: IB endometrioid adenocarcinomas (n=1), IC mesonephric carcinomas (n=1), IIIA endometrioid adenocarcino.mas (n=2), IIIA papillary serous carcinomas (n=1), and IIIC clear-cell carcinomas (n=1). Anastomotic leak (grade I) was the most commonly encountered postoperative complication. Two patients developed grade IV compli.cations due to septicemia and pulmonary embolism. No intraoperative mortality occurred. Postoperatively, all patients received chemotherapy (carboplatin and paclitaxel). In 1 patient, the clear-cell carcinoma histologic lesion relapsed within 6 months; the metastases spread to hepatic, pelvic, and mesenteric lymph nodes, and the patient died 5 months later. One patient with cytoreduction completeness of CC-2 developed hepatic metastases within 3 months and is still alive at a follow-up up 6 months. Remaining patients (n=4) are alive and disease free without evidence of recurrence of follow-ups at 35, 34, 19, and 7 months. CRS and HIPEC are well-tolerated and feasibly promising management modalities in PC from primary and recurrent endometrial carcinoma. Further research is needed for in-depth analysis.

We report a case of a 59-year-old woman with a very rare giant mesentery malignant solitary fibrous tumor that recurred as dedifferentiated liposarcoma. The woman was admitted to the hospital because of low abdominal pain. Radiological and biopsy findings revealed a multi-lobulated giant malignant solitary fibrous tumor that had invaded the inferior vena cava, abdominal aorta, and superior mesentery vessels. The tumor was completely removed during the first cytoreductive surgery. Histopathologically, tumor had a heterogeneous cell population, composed of spindle cells with fibrous collagen proliferation. The spindle cells were not arranged in a specific pattern. Immunohistochemistry revealed that the tumor cells were positive for CD34, CD99, Bcl-2, and smooth muscle actin( SMA) and negative for CD117, epithelial membrane antigen (EMA), CAM5.7, S100, desmin, and caldesmon. The tumor recurred 9 months after surgery, and another cytoreductive surgery was then performed. The postoperative histopathological appearance of the invaded area indicated a well-differentiated liposarcoma. Formation of tumorous bone was also noted in the same area, in addition to atypical mesenchymal cells and multi-vacuolated lipoblasts in the area of the well-differentiated liposarcoma. Proliferated spindle cells arranged in a storiform pattern were found in the area adjacent to the tumor. Immunohistochemical analysis revealed that the tumors cells were positive for SMA, HHF-35, and caldesmon and negative for CD117, CD34, and S100. A diagnosis of dedifferentiated liposarcoma was made.

Background Water lavage (WL) during gastrointestinal cancer surgery has osmotically mediated lytic effects on tumor cells. We investigated the safety and efficacy of WL with CRS-HIPEC. Methods This is a retrospective review, 1/2003–7/2014, of a single institution experience with CRS-HIPEC comparing patients who had WL (WL+) to those who did not (WL−). Results Of 157 CRS-HIPECs, 16 (10.2%) were WL+. WL+ had more PCI scores > 20 compared to WL− (56.3% vs 19.4%, respectively, p=0.003); however, the completeness of cytoreduction (CC) was similar. There were no differences in hospital length of stay or post-operative complications. The average POD 1 sodium (Na) level was statistically lower in the WL+ group (133.6±2.5 vs 135.5±3.2 mEq/L, p=0.023); however, the average Na at discharge for each group was 140 mEq/L. There were no differences in 3-year OS (3WL+:0.63 vs WL−:0.68, p=0.97) or RFS (WL+:0.32 vs WL−:0.39, p=0.47). A subset analysis for patients with PCI > 20 showed no difference between groups. Conclusions WL offers a low cost, safe and theoretically efficacious method of tumor cell lysis for peritoneal malignancy. PMID:28622839

Ovarian cancer (OC) is the third most common gynecologic malignancy worldwide. Most of cases it is of epithelial origin. At the present time there is not a standardized screening method, which makes difficult the early diagnosis. The 5-year survival is 90% for early stages, however most cases present at advanced stages, which have a 5-year survival of only 5-20%. GICOM collaborative group, under the auspice of different institutions, have made the following consensus in order to make recommendations for the diagnosis and management regarding to this neoplasia. The following recommendations were made by independent professionals in the field of Gynecologic Oncology, questions and statements were based on a comprehensive and systematic review of literature. It took place in the context of a meeting of two days in which a debate was held. These statements are the conclusions reached by agreement of the participant members. No screening method is recommended at the time for the detection of early lesions of ovarian cancer in general population. Staging is surgical, according to FIGO. In regards to the pre-surgery evaluation of the patient, it is recommended to perform chest radiography and CT scan of abdomen and pelvis with IV contrast. According to the histopathology of the tumor, in order to consider it as borderline, the minimum percentage of proliferative component must be 10% of tumor's surface. The recommended standardized treatment includes primary surgery for diagnosis, staging and cytoreduction, followed by adjuvant chemotherapy Surgery must be performed by an Oncologist Gynecologist or an Oncologist Surgeon because inadequate surgery performed by another specialist has been reported in 75% of cases. In regards to surgery it is recommended to perform total omentectomy since subclinic metastasis have been documented in 10-30% of all cases, and systematic limphadenectomy, necessary to be able to obtain an adequate surgical staging. Fertility-sparing surgery will be performed in certain cases, the procedure should include a detailed inspection of the contralateral ovary and also negative for malignancy omentum and ovary biopsy. Until now, laparoscopy for diagnostic-staging surgery is not well known as a recommended method. The recommended chemotherapy is based on platin and taxanes for 6 cycles, except in Stage IA, IB and grade 1, which have a good prognosis. In advanced stages, primary cytoreduction is recommended as initial treatment. Minimal invasion surgery is not a recommended procedure for the treatment of advanced ovarian cancer. Radiotherapy can be used to palliate symptoms. Follow up of the patients every 2-4 months for 2 years, every 3-6 months for 3 years and anually after the 5th year is recommended. Evaluation of quality of life of the patient must be done periodically. In the present, there is not a standardized screening method. Diagnosis in early stages means a better survival. Standardized treatment includes primary surgery with the objective to perform an optimal cytoreduction followed by chemotherapy Treatment must be individualized according to each patient. Radiotherapy can be indicated to palliate symptoms.

Population-based data on the percentage of colorectal cancer (CRC) patients with synchronous peritoneal carcinomatosis (PC) being treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are currently lacking. The current population-based study describes trends in the use of CRS-HIPEC in the Netherlands, one of the first countries where CRS and HIPEC was introduced. All patients diagnosed with synchronous PC of CRC between 2005 and 2012 were extracted from the Netherlands Cancer Registry (n = 4623). Patients with primary appendiceal cancer were excluded resulting in a study population of 4430 patients. Trends in the use of CRS-HIPEC over time were analyzed by means of a Cochrane-Armitage trend test. Survival proportions were calculated as the time between diagnosis and date of death or last follow-up (January 2014). Of the total 4430 patients with synchronous PC, 297 (6.4%) underwent treatment with CRS-HIPEC. The proportion of colorectal PC patients receiving CRS-HIPEC increased significantly over time from 3.6% in 2005-2006 to 9.7% in 2011-2012 (p < 0.0001). Overall median survival (MS) for patients treated with CRS-HIPEC was 32.3 months, whereas MS rates were respectively 12.6, 6.1 and 1.5 for months palliative chemotherapy with/without surgery, palliative surgery and best supportive care. The proportion of patients diagnosed with synchronous PC from CRC treated with CRS-HIPEC has increased significantly over time and currently almost 10% of PC patients are treated with CRS-HIPEC. Median survival in this population based group is 32.3 months. Copyright © 2015 Elsevier Ltd. All rights reserved.

Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) can be complicated by pulmonary emboli (PE). Patients are at high risk due to surgery, underlying malignancy, immobility and indwelling lines. This paper aims to identify clinically significant signs and symptoms preceding acute PE in post CRS-HIPEC patients, assess the PE investigative approach in this population and the significance of PE on patient management. 25 cases with a positive and 50 controls with a negative CTPA for PE were isolated from the peritonectomy database at St George Hospital Sydney, January 2006 to July 2013. Vital signs, patient symptoms, adjunct investigation findings and patient outcomes were collected and graphed in Microsoft Excel. P values and 95% confidence intervals were calculated using GraphPad Prism version 6. 25 of 562 (4.4%) CRS-HIPEC patients were diagnosed with acute PE. Raised body temperature was the only statistically significant clinical finding that differentiated cases from controls (p value 0.02). Arterial blood gas results did not correlate with PE (p values 0.62; 0.29; 0.55, 0.84). Troponin, ECG and CXR were not routinely conducted. CXR and CTPA findings were similar between cases and controls (Table 4). PE patients required lower supplementary oxygen and escalation of care. Body temperature is the only statistically significant clinical finding observed with PE. We recommend a standardised investigative approach consisting of troponin, ECG and CXR. PE in CRS-HIPEC does not cause significant cardio-respiratory dysfunction, or escalation of care. PE rates are higher than other major surgeries, thus we propose a trial with increased chemical prophylaxis in CRS-HIPEC patients. Copyright © 2015 Elsevier Ltd. All rights reserved.

The combination of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is a promising treatment option for selected patients with peritoneal carcinomatosis. This retrospective study investigated the relationship between baseline nutritional assessment with subsequent parenteral nutritional (PN) and clinical outcomes in cancer patients undergoing CRS and HIPEC. A consecutive series of 60 patients undergoing CRS and HIPEC at our institution between January 2009 and May 2011. Subjective Global Assessment (SGA) was used to assess nutritional status. Patients were classified preoperatively as: well nourished (SGA-A), mildly-moderately malnourished (SGA-B), and severely malnourished (SGA-C). For PN, patients were divided into 2 groups: those who received PN (PN+) and those who did not receive PN (PN-). The primary outcomes of interest were length of stay (LOS), postoperative complications, ECOG performance status (PS) and survival. LOS was calculated as the number of days in the hospital post surgery. Performance status was measured on a scale of 0-4. Survival was calculated from the date of first visit to the date of death/last contact. Of 60 patients, 19 were males and 41 females. The mean age at presentation was 50.3 years. The most common cancer types were colorectal (n = 24) and gynecologic (n = 19) with the majority of patients (n = 47) treated previously before coming to our institution. 33 patients were SGA-A, 22 SGA-B and 5 SGA-C prior to surgery. Of a total of 60 patients, 31 received PN. Mean LOS for the entire cohort was 16.2 days (SD = 9.8). Mean LOS for preoperative SGA-A, SGA-B and SGA-C were 15.0, 15.2 and 27.8 days respectively (ANOVA p = 0.02). Overall incidence of complications was 26.7% (16/60). Complications were recorded in 9 of 33 (27.3%) preoperative SGA-A patients and 7 of 27 (25.9%) SGA-B + C patients (p = 0.91). The median overall survival was 17.5 months (95% CI = 13.0 to 22.1 months). Median survival for preoperative SGA-A and SGA-B + C cohorts was 22.4 and 10.4 months respectively (p = 0.006). The preoperative SGA predicts LOS and survival in cancer patients undergoing HIPEC. Future randomized clinical trials in this patient population should investigate the systematic provision of PN to all malnourished patients in the preoperative period for a minimum of 7-10 days with the continuation of PN in the postoperative period.

Gastrointestinal leak (GIL) after cytoreductive surgery with heated intraperitoneal chemotherapy (CRS/HIPEC) is associated with significant morbidity and mortality. This study aimed to identify GIL prognostic factors and its impact on overall survival. A retrospective analysis of a prospectively maintained database comprising 1270 CRS/HIPEC procedures was performed. Type of GIL, functional and resection status, morbidity, mortality, and survival were reviewed. Gastrointestinal leaks were identified in 8.7% (110/1270) of CRS/HIPEC procedures, including 53 anastomotic leaks (4.2%), 53 hollow viscus perforations (4.2%), and four leaks at unknown sites. The multivariate predictors of leak were Eastern Cooperative Oncology Group (ECOG) functional status (ECOG 1 vs. 0: odds ratio [OR] 2.12, p = 0.009; ECOG 2 vs. 0: OR 2.90, p = 0.004), and number of anastomoses (OR 5.34; p < 0.0001). The in-hospital mortality rate for the GIL cohort was 21.8% (24/110), with a 72% (80/110) reoperation rate. The leak cohort had a higher major morbidity rate (88.3 vs. 23.3%; p < 0.0001), a longer hospital stay (39.0 vs. 9.9 days; p < 0.0001), and a longer intensive care unit (ICU) stay (7.7 vs. 1.7 days; p = 0.0003). After surgical mortality was excluded, the overall survival periods for the leak and no-leak patients with complete cytoreduction were respectively 1.5 and 4.98 years (p = 0.0001). Clinically significant decreases in survival were observed for all primary malignancies. Gastrointestinal leak after CRS/HIPEC is a source of significant mortality, with a decrease in overall survival even after complete CRS. Preoperative functional status and number of anastomoses are predictors of leak for CRS/HIPEC patients.

Aim of the study is to assess the reliability and correlation with surgical peritoneal cancer index (PCI) of combined PET/CT and ceCT scans (PET/ceCT) performed in a session in patients with peritoneal carcinomatosis candidates for cytoreductive surgery (CS) and hyperthermic intraperitoneal chemotherapy (HIPEC). We retrospectively analyzed data collected from 27 patients with different types of peritoneal carcinomatosis candidates to CS + HIPEC who underwent FDG PET/ceCT in a single session. Two nuclear medicine physicians and two radiologists independently and blindly evaluated PET/CT and ceCT imaging, respectively. In the case of discordance, the consensus was reached by a discussion between the specialists. Moreover, the combined images were evaluated by all the specialists in consensus. The PCIs obtained from surgical look, PET/CT, ceCT, and PET/ceCT were compared with each other. The coefficients of correlation (r) were calculated. The study was conducted after approval of local ethics committee. Surgical PCI was available in 21 patients. The coefficient of correlation between PCI of PET/CT and surgery was 0.528, while it resulted higher between PET/ceCT and surgery (r = 0.878), very similar to ceCT and surgery (r = 0.876). The r coefficient between surgical PCI and PET/CT was higher in patients with a non-mucinous cancer (n = 12) than the counterpart (0.601 vs. 0.303) and the addition of ceCT significantly increases the correlation (r = 0.863), which is anyway similar to ceCT alone (r = 0.856). PET/ceCT as single examination is more accurate than PET/CT but not than ceCT alone for the definition of PCI in a selected group of patients candidates to CS + HIPEC.

To evaluate the accuracy of MDCT in the preoperative definition of Peritoneal Cancer Index (PCI) in patients with advanced ovarian cancer who underwent a peritonectomy and hyperthermic intraperitoneal chemotherapy (HIPEC) after neoadjuvant chemotherapy to obtain a pre-surgery prognostic evaluation and a prediction of optimal cytoreduction surgery. Pre-HIPEC CT examinations of 43 patients with advanced ovarian cancer after neoadjuvant chemotherapy were analyzed by two radiologists. The PCI was scored according to the Sugarbaker classification, based on lesion size and distribution. The results were compared with macroscopic and histologic data after peritonectomy and HIPEC. To evaluate the accuracy of MDCT to detect and localize peritoneal carcinomatosis, both patient-level and regional-level analyses were conducted. A correlation between PCI CT and histologic values for each patient was searched according to the PCI grading. Considering the patient-level analysis, CT shows a sensitivity, specificity, PPV, NPV, and an accuracy in detecting the peritoneal carcinomatosis of 100 %, 40 %, 93 % 100 %, and 93 %, respectively. Considering the regional level analysis, a sensitivity, specificity, PPV, NPV, and diagnostic accuracy of 72 %, 80 %, 66 %, 84 %, and 77 %, respectively were obtained for the correlation between CT and histology. Our results encourage the use of MDCT as the only technique sufficient to select patients with peritoneal carcinomatosis for cytoreductive surgery and HIPEC on the condition that a CT examination will be performed using a dedicated protocol optimized to detect minimal peritoneal disease and CT images will be analyzed by an experienced reader.

The majority of ovarian cancer patients are initially diagnosed at an advanced-stage [1]. Upper abdominal bulky metastasis cephalad to the greater omentum reported to be present in 42% of patients [2]. Many complex surgical procedures such as splenectomy, pancreatectomy, mobilization and partial resection of liver, porta hepatis dissection, diaphragmatic peritonectomy and resection are frequently performed to achieve complete resection of metastatic disease [3]. Our aim in this surgical film is to show the resection of a left sided diaphragmatic implant located beneath the heart, with dissection from the pericardium after entrance to the pericardial cavity. Additionally, step by step splenectomy with distal pancreatectomy also presented. A 67years-old woman referred to our clinic for interval debulking for advanced stage suboptimally debulked high grade serous ovarian carcinoma. The tumor invading distal pancreas, hilum and parenchyma of spleen is clearly seen on magnetic resonance imaging. Another implant was also visible on left side of the diaphragm. We achieved complete cytoreduction with no macroscopic disease at the end of the surgery. She stayed at the intensive care unit for two days and in our clinic for seven days. We did not encounter any grade 3 or 4 adverse event in post-operative period. The surgical treatment of ovarian cancer has evolved in time in favor of radical surgery. The surgical team should be highly motivated, skilled and experienced for this complex procedures, since being able to reach complete cytoreduction is the most important predictor of survival in ovarian cancer patients.

Abstract. Ovarian cancer is the most deadly gynecologic cancer, a fact which is attributable to poor early detection and survival once the disease has reached advanced stages. Intraoperative laparoscopic volume holographic imaging has the potential to provide simultaneous visualization of surface and subsurface structures in ovarian tissues for improved assessment of developing ovarian cancer. In this ex vivo ovarian tissue study, we assembled a benchtop volume holographic imaging system (VHIS) to characterize the microarchitecture of 78 normal and 40 abnormal tissue specimens derived from ovarian, fallopian tube, uterine, and peritoneal tissues, collected from 26 patients aged 22 to 73 undergoing bilateral salpingo-oophorectomy, hysterectomy with bilateral salpingo-oophorectomy, or abdominal cytoreductive surgery. All tissues were successfully imaged with the VHIS in both reflectance- and fluorescence-modes revealing morphological features which can be used to distinguish between normal, benign abnormalities, and cancerous tissues. We present the development and successful application of VHIS for imaging human ovarian tissue. Comparison of VHIS images with corresponding histopathology allowed for qualitatively distinguishing microstructural features unique to the studied tissue type and disease state. These results motivate the development of a laparoscopic VHIS for evaluating the surface and subsurface morphological alterations in ovarian cancer pathogenesis. PMID:24676382

Ovarian clear cell carcinoma represents a distinct histopathological subtype of epithelial ovarian cancer, with poor outcomes, especially in cases diagnosed in advanced stages of disease. However, even in these cases, it seems that the most effective treatment remains debulking surgery to no residual disease. We present the case of a 56-year-old patient diagnosed with a large pelvic mass invading the rectosigmoidal colon, and ileal loop who was successfully submitted to cytoreductive surgery to no residual disease. The histopathological studies demonstrated the presence of a well-differentiated clear cell ovarian carcinoma of the ovary. At 1-year follow-up there is no evidence of residual disease.

Water lavage (WL) during gastrointestinal cancer surgery has osmotically mediated lytic effects on tumor cells. We investigated the safety and efficacy of WL with CRS-HIPEC. This is a retrospective review, 1/2003-7/2014, of a single institution experience with CRS-HIPEC comparing patients who had WL (WL+) to those who did not (WL-). Of 157 CRS-HIPECs, 16 (10.2%) were WL+. WL+ had more PCI scores >20 compared to WL- (56.3% vs 19.4%, respectively, p = 0.003); however, the completeness of cytoreduction (CC) was similar. There were no differences in hospital length of stay or post-operative complications. The average POD 1 sodium (Na) level was statistically lower in the WL+ group (133.6 ± 2.5 vs 135.5 ± 3.2 mEq/L, p = 0.023); however, the average Na at discharge for each group was 140 mEq/L. There were no differences in 3-year OS (3WL+:0.63 vs WL-:0.68, p = 0.97) or RFS (WL+:0.32 vs WL-:0.39, p = 0.47). A subset analysis for patients with PCI >20 showed no difference between groups. WL offers a low cost, safe and theoretically efficacious method of tumor cell lysis for peritoneal malignancy. Copyright © 2017 Elsevier Inc. All rights reserved.

Purpose The current study examined prospective relationships between preoperative depressive symptoms and short-term (30-day morbidity and readmission) and long-term (overall survival) outcomes after hyperthermic intraperitoneal chemotherapy with cytoreductive surgery (HIPEC + CS). Methods Ninety-eight patients scheduled for HIPEC + CS completed the Center for Epidemiologic Studies–Depression (CES-D) scale before surgery. Demographic and disease-specific factors and information about morbidity and readmission within 30 days after discharge were gathered from medical records. Survival was measured from date of surgery to death. Results Twenty-eight percent of patients had CES-D scores indicative of clinically significant depressive symptoms. Thirty-day morbidity occurred in 31.9% of patients and readmission in 22.2%. At the time of analysis (median follow-up of 49 months), 71.6% of patients were deceased, with median survival time of 11 months for those who died. After adjusting for relevant preoperative demographic and disease-specific factors, depressive symptoms were associated with greater odds of 30-day morbidity (n = 68; odds ratio, 5.50; 95% CI, 1.23 to 24.73; P = .03) and greater likelihood of 30-day readmission (n = 72; odds ratio, 5.92; 95% CI, 1.27 to 27.64; P = .02). Depressive symptoms were associated with shorter survival after adjustment for preoperative demographic and disease-specific factors (n = 87; hazard ratio, 1.88; 95% CI, 1.07 to 3.31; P = .03). This association was no longer significant when intraoperative/postoperative prognostic variables were added to the statistical model (n = 87; hazard ratio, 1.31; 95% CI, 0.72 to 2.37; P = .37). Conclusion Patients with clinically significant levels of preoperative depressive symptoms are at risk for poor clinical outcomes after HIPEC + CS, including greater risk of 30-day morbidity and readmission. Further research is warranted to determine biobehavioral mechanisms and examine whether effective interventions targeting preoperative depressive symptoms can reduce postoperative risk in this patient population.

Targeted medications for metastatic adult Xp11.2 translocation renal cell carcinoma (RCC) remain to be identified. We herein report a case of metastatic Xp11.2 translocation RCC controlled with cytoreductive nephrectomy (CN) and axitinib therapy. A 57-year-old woman complained of fatigue and low back pain. Imaging studies revealed a right renal tumor, with multiple lung and mediastinal lymph node metastases. Although the patient received 10 mg axitinib therapy for 5 months at the hospital she was initially admitted to, the size of the primary and metastatic lesions was not reduced. Thus, she was referred to the Tokyo Women's Medical University Hospital (Tokyo, Japan) for further treatment, where she underwent CN. On macroscopic examination, almost the entire kidney was replaced by a yellowish brown tumor >80 mm in diameter. Immunohistochemical examination confirmed the diagnosis of Xp11.2 translocation RCC. One month after surgery, axitinib therapy was resumed and the size of the metastatic lesions gradually decreased. These findings suggest that axitinib therapy is effective for adult Xp11.2 translocation RCC.

The prophylactic use of a preoperative, intraoperative, and postoperative high-dose continuous octreotide acetate infusion was evaluated for its ability to minimize the incidence of carcinoid crises during neuroendocrine tumor (NET) cytoreductive surgeries. A retrospective study was approved by the institutional review boards at Ochsner Medical Center-Kenner and Louisiana State University Health Sciences Center. Ochsner Medical Center-Kenner operating room and multispecialty NET clinic. One hundred fifty consecutive patients who underwent a total of 179 cytoreductive surgeries for stage IV, small bowel NETs. All patients received a 500-μg/h infusion of octreotide acetate preoperatively, intraoperatively, and postoperatively. Anesthesia and surgical records were reviewed. Carcinoid crisis was defined as a systolic blood pressure of less than 80mm Hg for greater than 10minutes. Patients who experienced intraoperative hypertension or hypotension, profound tachycardia, or a "crisis" according to the operative note were also reviewed. One hundred sixty-nine (169/179; 94%) patients had normal anesthesia courses. The medical records of 10 patients were further investigated for a potential intraoperative crisis using the aforementioned criteria. Upon review, 6 patients were determined to have had a crisis. The final incidence of intraoperative crisis was 3.4% (6/179). A continuous high-dose infusion of octreotide acetate intraoperatively minimizes the incidence of carcinoid crisis. We believe that the low cost and excellent safety profile of octreotide warrant the use of this therapy during extensive surgical procedures for midgut and foregut NETs.

Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is an appropriate treatment for select patients with peritoneal carcinomatosis. While most commonly performed through an open incision, the laparoscopic approach has been reported and offers short-term benefits. A robotic-assisted approach for carcinomatosis of gastrointestinal origin, however, has not yet been described. We report our approach to robotic-assisted CRS-HIPEC for a patient with a perforated appendiceal mucocele. Our dynamic video highlights the advantages of this approach. Our patient was a 57-year-old woman with minimal residual disseminated peritoneal adenomucinosis (DPAM), having a peritoneal carcinomatosis index (PCI) score of 1. She had a previous surgical history of a Roux-en-Y gastric bypass. A robotic-assisted approach was utilized using the Intuitive daVinci Xi robotic surgical system through 4 ports. No laparoscopic assistant port was required. The operative time was 426 min, and the estimated blood loss was 50 cc. The greater omentum, falciform ligament, bilateral ovaries, and two small areas of tumor implant were resected. The post-operative length of stay was 4 days, and the patient had regained bowel function by post-operative day 2. Our video demonstrates the feasibility of a robotic-assisted CRS-HIPEC in a patient with minimal, residual DPAM. Similar to a laparoscopic approach, the short-term outcomes are improved as compared to an open approach. An MIS approach to CRS-HIPEC, now with the first-reported robotic-assisted approach, is a viable option for select patients with peritoneal tumors.

Cytoreductive Surgery in the Management of Renal Tumours: Rationale, Current Evidence and Future Perspectives.

Renal cell carcinoma accounts for 3% of adult solid malignant tumours. Approximately 25% of the patients present with metastatic disease at presentation. In the era of immunotherapy (interferon alpha-2b and interleukin-2), studies showed significant survival benefit with cytoreductive nephrectomy (CRN) followed by interferon alpha-2b than interferon alpha 2-b alone. Introduction of targeted therapies (vascular endothelial growth factor receptor-tyrosine kinase inhibitors, mammalian target of rapamycin inhibitors) in 2005 generated a great interest in the management of metastatic renal cell carcinoma (mRCC) as these drugs exhibited tumour shrinkage in the primary tumour as well as in the metastatic site/s. Though there is no level 1 evidence, many studies have shown the usefulness of cytoreductive nephrectomy along with targeted therapy as against to targeted therapy alone. This review is aimed at the rationale behind the cytoreductive nephrectomy in mRCC, the current evidence and what is in store for the future. A detailed search on the management of mRCC was carried out on MEDLINE, Embase, CANCERLIT and Cochrane Library databases using the key words "cytoreductive nephrectomy", "immunotherapy" and "targeted therapy" since 1980 till 2015. Original articles, review articles, monograms, book chapters on metastatic renal cancer and textbooks on urologic oncology, oncology and urology were reviewed. Various international guidelines on this issue were also studied. An identical search was performed using the American Society of Clinical Oncology Abstract database. Trials in the progress or recently completed that were relevant to this paper were identified through clinicaltrials.gov. The latest information for new articles ahead of publication was last accessed in November 2015. CRN has remained an integral part to the management of metastatic renal cell carcinoma mainly for the patients with good performance status, life expectancy of more than 12 months and in the absence of adverse prognostic factors. It had shown measurable survival benefit in the era of immunotherapy (CRN + immunotherapy vs. immunotherapy alone). In the era of targeted therapy, many studies have shown significant survival benefit with CRN + targeted therapy. However, there is no clear level 1 evidence to support this. The ongoing trials (CARMENA and European Organisation for Research and Treatment of Cancer SURTIME) would perhaps guide us in the way in which we should manage mRCC disease in the future. Maybe we may find some answers on the issues of the effectiveness of targeted therapy, the timing of CRN and sequencing these treatment arms once the results of these ongoing and future trials are through.

Surgical management in epithelial ovarian cancer (EOC) has a significant impact in overall survival (OS) and progression free survival (PFS). Brazilian Society of Surgical Oncology (BSSO) supported a taskforce with experts for consensus: experienced and specialized trained surgeons, in cancer centers, provide the best EOC surgery. Laparoscopic and/or radiological staging prognosticate the possibility of complete cytoreduction (CC0) and help to reduce unnecessary laparotomies. Surgical techniques were reviewed. Multidisciplinary input is essential for treatment planning. Quality assurance criteria are proposed and need national consensus. Genetic testing is mandatory. This consensus states the final recommendations from BSSO for management of EOC. This article is protected by copyright. All rights reserved. This article is protected by copyright.

Pseudomyxoma peritonei (PMP) is a rare carcinomatosis limited to the peritoneal cavity, mainly supplied by the superior mesenteric artery (SMA). The only curative treatment is cytoreductive surgery (CRS) associated with hyperthermic intraperitoneal chemotherapy. This study aimed to evaluate the ability of blood flow volume (BFV) recorded in the SMA using Doppler ultrasonography pre-operatively to predict the extent and resectability of the disease and post-operatively to assess clinical outcome. BFV was measured in the SMA of forty-nine patients before and the year following CRS. Patients were categorized in 3 groups according to clinical and surgical outcomes: group-1 (n = 22): patient with completed CRS, group-2 (n = 16): incomplete resection with slowly progressive disease (alive at 2 years without severe clinical symptoms), group-3 (n = 11): incomplete resection and with severe clinical symptoms or dead within two years. Pre-operative mean SMA BFV was higher in group-2 (510 mL/min, p = 0.027) and in group-3 (572 mL/min, p = 0.004) than in group-1 (378 mL/min). After surgery, BFV dropped to normal values (203 mL/min, p = 0.001) in group-1, and to 423 mL/min (p = 0.047) in group-2. It remained elevated in group-3 (626 mL/min, p = 0.566). BFV allowed stratification of 1) resectability before CRS (group-2 and -3 vs group-1, area under the ROC curve: 0.794 [0.650-0.939]), and 2) non progression after incomplete CRS (group-3 vs group-2, area under the ROC curve: 0.827 [0.565-1.00]. Pre-operative BFV in the SMA correlates with extent and resectability of PMP. After incomplete surgery, post-operative BFV might aid in identifying patients who may benefit of post-operative therapy.

Current role of hyperthermic intraperitoneal chemotherapy in the treatment of peritoneal carcinomatosis from colorectal cancer

PubMed Central

Rampone, Bernardino; Schiavone, Beniamino; Martino, Antonio; Confuorto, Giuseppe

2010-01-01

Peritoneal carcinomatosis is one of the most common routes of dissemination of colorectal cancer (CRC). It is encountered in 7% of patients at primary surgery, while it develops in about 4% to 19% of patients after curative surgery and in up to 44% of patients with recurrent CRC. Peritoneal involvement from colorectal malignancies has been considered traditionally as a manifestation of terminal disease, due to limited response to conventional surgical and chemotherapeutic treatments. In the past few years the introduction of cytoreductive surgery combined with hyperthermic intraperitoneal chemoperfusion has shown promising results in selected patients. Currently, the surgical management of peritoneal surface malignancies of colonic origin with this combined locoregional therapy has resulted in a significant improvement in survival of these patients. However, further controlled studies will help to standardize indications and the technique of this locoregional therapy in order to achieve an improvement of morbidity and mortality rates.

Epithelial ovarian cancer remains to be the most deadly gynecologic cancer among the female population. Carcinogenesis and abdomen extension are the reasons why ovarian cancer is still examined in advances stages. Ovarian cancer frequent metastasizes to the uterus, rectosigmoid colon, and other pelvic structures by intraperitoneal seeding of tumor deposits, as well as direct extension. Multiple modalities of therapy are utilized in the management of the disease. Numerous medical trials and research programs have demonstrated the most important role of surgery in the treatment of this disease. A vast majority of authors are of the opinion that the surgical interventions have a major influence on the overall survival (OS) and progression free survival (PFS) in ovarian cancer cases. The paper presents a case of a 35-year-old woman diagnosed with advanced ovarian cancer who underwent modified posterior exenteration as a part of extensive cytoreductive surgery

Malignancies of the peritoneum remain a challenge in any hospital that accepts to manage them, due not only to difficulties associated with the complexity of the procedures involved but also the costs, which - in Italy and other countries that use a diagnosis-related group (DRG) system - are not adequately reimbursed. We analyzed data relative to 24 patients operated on between September 2010 and May 2013 with special regard to operating room expenditure, ICU stay, duration of hospitalization, and DRG reimbursement. The total costs per patient included clinical, operating room, procedure, pathology, imaging, ward care, allied healthcare, pharmaceutical, and ICU costs. Postoperative hospital stay, drugs and materials, and operating room occupancy were the main factors affecting the expenditure for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. We had a median hospitalization of 14 days, median ICU stay of 2.4 days, and median operating room occupancy of 585 min. The median expenditure for each case was € 21,744; the median reimbursement by the national health system € 8,375. In a DRG reimbursement system, the economic effort in the management of patients undergoing peritonectomy procedures may not be counterbalanced by adequate reimbursement. Joint efforts between medical and administration parties are mandatory to develop appropriate treatment protocols and keep down the costs. Copyright © 2014 Elsevier Ltd. All rights reserved.

Fluorescent imaging of cancerous tissues for targeted surgery

PubMed Central

Bu, Lihong; Shen, Baozhong; Cheng, Zhen

2014-01-01

To maximize tumor excision and minimize collateral damage is the primary goal of cancer surgery. Emerging molecular imaging techniques have to “image-guided surgery” developing into “molecular imaging-guided surgery”, which is termed “targeted surgery” in this review. Consequently, the precision of surgery can be advanced from tissue-scale to molecule-scale, enabling “targeted surgery” to be a component of “targeted therapy”. Evidence from numerous experimental and clinical studies has demonstrated significant benefits of fluorescent imaging in targeted surgery with preoperative molecular diagnostic screening. Fluorescent imaging can help to improve intraoperative staging and enable more radical cytoreduction, detect obscure tumor lesions in special organs, highlight tumor margins, better map lymph node metastases, and identify important normal structures intraoperatively. Though limited tissue penetration of fluorescent imaging and tumor heterogeneity are two major hurdles for current targeted surgery, multimodality imaging and multiplex imaging may provide potential solutions to overcome these issues, respectively. Moreover, though many fluorescent imaging techniques and probes have been investigated, targeted surgery remains at a proof-of-principle stage. The impact of fluorescent imaging on cancer surgery will likely be realized through persistent interdisciplinary amalgamation of research in diverse fields. PMID:25064553

Background Peritoneal carcinomatosis (PC) in the setting of mucinous appendiceal neoplasms is characterized by the intraperitoneal accumulation of mucinous ascites and mucin-secreting epithelial cells that leads to progressive compression of intra-abdominal organs, morbidity, and eventual death. We assessed postoperative and oncologic outcomes after aggressive surgical management by experienced surgeons. Methods We analyzed clinicopathologic, perioperative, and oncologic outcome data in 282 patients with PC from appendiceal adenocarcinomas between 2001 and 2010 from a prospective database. Kaplan–Meier survival curves and multivariate Cox-regression models were used to identify prognostic factors affecting oncologic outcomes. Results Adequate cytoreduction was achieved in 82% of patients (completeness of cytoreduction score (CC)-0: 49%; CC-1: 33%). Median simplified peritoneal cancer index (SPCI), operative time, and estimated blood loss were 14 (range, 0–21), 483.5 min (range, 46–1,402), and 800 ml (range, 0–14,000), respectively. Pathology assessment demonstrated high-grade tumors in 36% of patients and lymph node involvement in 23% of patients. Major postoperative morbidity occurred in 70 (25%) patients. Median overall survival was 6.72 years (95% confidence interval (CI), 4.17 years not reached), with 5 year overall survival probability of 52.7% (95% CI, 42.4, 62%). In a multivariate Cox-regression model, tumor grade, age, preoperative SPCI and chemo-naïve status at surgery were joint significant predictors of overall survival. Tumor grade, postoperative CC-score, prior chemotherapy, and preoperative SPCI were joint significant predictors of time to progression. Conclusions Aggressive management of PC from mucinous appendiceal neoplasms, by experienced surgeons, to achieve complete cytoreduction provides long-term survival with low major morbidity.

Ovarian cancer carries a significant mortality. Since symptoms tend to be minimal, the disease is often diagnosed when peritoneal metastases are already present. The standard of care in advanced ovarian cancer consists of platinum-based chemotherapy combined with cytoreductive surgery. Unfortunately, even after optimal cytoreduction and adjuvant chemotherapy, most patients with stage III disease will develop a recurrence. Intraperitoneal administration of chemotherapy is an alternative treatment for patients with localized disease. The pharmacological and physiochemical properties of melflufen, a peptidase potentiated alkylator, raised the hypothesis that this drug could be useful in ovarian cancer and particularily against peritoneal carcinomatosis. In this study the preclinical effects of melflufen were investigated in different ovarian cancer models. Melflufen was active against ovarian cancer cell lines, primary cultures of patient-derived ovarian cancer cells, and inhibited the growth of subcutaneous A2780 ovarian cancer xenografts alone and when combined with gemcitabine or liposomal doxorubicin when administered intravenously. In addition, an intra- and subperitoneal xenograft model showed activity of intraperitoneal administered melflufen for peritoneal carcinomatosis, with minimal side effects and modest systemic exposure. In conclusion, results from this study support further investigations of melflufen for the treatment of peritoneal carcinomatosis from ovarian cancer, both for intravenous and intraperitoneal administration.

Peritoneal carcinomatosis (PC) is manifested in up to 40% of gastric cancer (GC) patients, after which their 5-year survival drops to less than 5%. The currently most acceptable treatment option for advanced GC (AGC) is systemic chemo and radio therapies with however generally very unsatisfying results and this led to a resurgence of interest in regional therapies like cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Small trials have indicated an association with prolonged survival when applying this technique to AGC manifesting with PC. High procedure-related morbidity and mortality associated with the CRS-HIPEC approach have however brought by a polemic on the merits of the latter: with the advent of regulatory approval of more effective as well as novel, more personalized treatment options in AGC, along with advances in tailoring investigational agents specifically for peritoneal delivery, there clearly is a need to outline the appropriate role of CRS-HIPEC in this disease. In a clear objective to improve the therapeutic efficiency of HIPEC, there have been immense developments in the technical aspects of this technology including the use of nanotechnology in more precise drug delivery systems (DDS) or choice of more efficient drugs such as gene-target technology, laparoscopy and so on. Henceforth, in this review, we will be highlighting the past and current status of the CRS + HIPEC procedure, shedding light on the pros and cons in order to boost up the efficiency of this multimodality approach.

Causes of peritoneal carcinomatosis (PC) in patients with a history of breast carcinoma include both metastatic breast carcinoma (MBC) and primary peritoneal/ovarian carcinoma (PPOC). The origin of PC is important to determine the appropriate treatment strategy. Cytological examination of the peritoneal fluid (PF), which may be the first diagnostic approach to PC, is of distinct value in confirming the presence of malignant cells and determining the origin of PC. We analyzed the clinicopathological and cytomorphological characteristics of 33 patients with a history of breast carcinoma whose PF cytology contained malignant cells. Cases showing positive immunoreactivity for PAX8 and a lack of GATA3 expression were considered as PPOC. Sixteen patients developed PC caused by PPOC. PPOC patients were characterized by early-stage primary breast carcinoma, absence of non-peritoneal MBC before PC, and normal serum levels of CEA and CA15-3. Fourteen PPOC patients had pathogenic germline BRCA mutations. Cytological examination revealed that most of the PPOC cases had a dominant papillary arrangement of the tumor cells with severe nuclear pleomorphism, occasional bizarre nuclei, and atypical mitotic figures. Patients with PPOC who underwent cytoreductive surgery had a significantly longer survival time compared to those who did not, or MBC patients. In patients with a history of breast carcinoma presenting with PC, the presence of early-stage primary breast carcinoma, no prior non-peritoneal MBC, and a dominant papillary cellular arrangement pattern in the PF cytology were independent predictors of PPOC. Cytoreductive surgery significantly improved survival for patients with PPOC.

This systematic review aimed to provide an overview of (inter)national guidelines on the treatment of peritoneal metastases of colorectal cancer origin (PMCRC) and to determine the degree of consensus and available evidence with identification of topics for future research. A systematic search of MEDLINE, Embase, PubMed as well as Tripdatabase, National Guideline Clearinghouse, BMJ Best Practice and Guidelines International Network was performed to identify (inter)national guidelines and consensus statements from oncological or surgical societies on PMCRC. The quality of guidelines was assessed using the AGREE-II score. Topics followed by recommendations were extracted from the guidelines. The recommendations, highest level of supporting evidence and the degree of consensus were determined for each topic. Twenty-one guidelines were included, in most (15) of which cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) was recommended in selected patients based on level 1b evidence. Substantial consensus was also reached on the benefit of multidisciplinary team discussion and the achievability of a (near) complete cytoreduction (CC0-1) without supporting evidence. Both evidence and consensus were lacking regarding other aspects including preoperative positron emission tomography/CT, second look surgery in high risk patients, the optimal patient selection for CRS/HIPEC, procedural aspects of HIPEC and (perioperative) systemic therapy. In currently available guidelines, evidence and consensus on the treatment strategy for PMCRC are lacking. Updates of guidelines are ongoing and future (randomized) clinical trials should contribute to multidisciplinary and international consensus on treatment strategies for PMCRC.

Management of intracranial chordomas remains challenging, despite improvements in microsurgical techniques and radiotherapy. Here, we analyzed the prognostic factors associated with improved rates of tumor control in patients with intracranial chordomas, who received either gross (GTR) or subtotal resections (STR). A retrospective review was performed to identify all patients who were undergoing resection of their intracranial chordomas at the Ronald Reagan University of California Los Angeles Medical Center from 1990 to 2011. In total, 57 patients undergoing 81 resections were included. There were 24 females and 33 males with a mean age of 44.6 years, and the mean tumor diameter was 3.36 cm. The extent of resection was not associated with recurrence. For all 81 operations, the 1 and 5 year progression free survival (PFS) was 87.5 and 40.4%, and 88.0 and 33.6% for STR and GTR, respectively (p=0.90). Adjuvant radiotherapy was associated with improved rates of PFS (hazard ratio [HR] 0.20; p=0.009). Additionally, age >45 years (HR 5.88; p=0.01) and the presence of visual deficits (HR 7.59; p=0.03) were associated with worse rates of tumor control. Tumor size, sex, tumor histology, and recurrent tumors were not predictors of recurrence. Younger age, lack of visual symptoms on presentation and adjuvant radiotherapy were associated with improved rates of tumor control following surgery. However, GTR and STR produced comparable rates of tumor control. The surgical management of intracranial chordomas should take a conservative approach, with the aim of maximal but safe cytoreductive resection with adjuvant radiation therapy, and a major focus on quality of life.

Peritoneal carcinomatosis is a common evolution of neoplasms and the terminal stage of disease. A new therapeutic technique, based on the total surgical removal of peritoneal lesions (peritonectomy procedure - PP) combined with the intraperitoneal chemohyperthermia (IPCH), has been developed. Proper patient selection is mandatory for optimizing the results of treatment. The aim of this study was to investigate the role of [(18)F]fluoro-2-deoxy-d-glucose Positron Emission Tomography/Computed Tomography ((18)F-FDG PET/CT) in patients with peritoneal carcinosis selected to undergo PP and IPCH. Furthermore, we aimed to identify characteristic patterns of abdominal(18)F-FDG uptake and to correlate these patterns with available anatomic findings after surgery. Patients with either histologically confirmed peritoneal carcinosis or suspected upon clinical follow-up and/or imaging findings were prospectively submitted to pre-surgery (18)F-FDG PET/CT scan. Only those patients without evidence of extra-peritoneal metastases at PET/CT scan were treated with PP and IPCH. 11 patients with peritoneal carcinomatosis (5 colorectal, 4 ovarian, 1 pancreatic) and 1 unknown primitive cancer, were eligible for the study. In all cases PET/CT scan showed multiple peritoneal implants. In 6 out of 11 cases (54%) metastases were evidenced by (18)F-FDG PET/CT: 2 cases with liver metastases; 1 case with bone metastases; 3 patients with lymph-node lesions. Two distinct imaging patterns, with focal or diffuse increased (18)F-FDG uptake, were recognized. PP+IPCH of patients selected by (18)F-FDG PET/CT seems to be safe and feasible. PET/CT scan appears as a reliable tool for the detection, characterization of peritoneal implants with potential impact in the therapeutic management of these patients.

Ovarian peritoneal carcinomatosis is a pathology for which effective cures are currently lacking. New research protocols seek to eradicate residual micrometastases following cytoreductive surgery by using hyperthermic intraperitoneal chemotherapy (HIPEC) or radioimmunotherapy (RIT). This study aims to first develop alpha-RIT using an anti-CD138 mAb radiolabeled with an alpha-emitter, bismuth-213 ((213)Bi-B-B4) and HIPEC in a nude mouse model and second to compare and combine these techniques. A murine model of postoperative ovarian peritoneal carcinomatosis was established. A pilot group of six mice received an intraperitoneal injection of luciferase-tagged SHIN-3 cells and bioluminescence was measured every day. Cytoreductive surgery was performed at day 14 (n = 4) and 29 (n = 2). Because the residual bioluminescence signal measured after surgery was equivalent to that obtained 3 days after the graft, HIPEC or alpha-RIT treatments were applied 3 days after the graft. Ten mice were treated by HIPEC with cisplatine (37.5 mg/mL), 11 with 7.4 MBq of (213)Bi-B-B4, seven with 11.1 MBq of (213)Bi-B-B4, and 10 mice were treated with the combined therapy (HIPEC + 7.4 MBq of (213)Bi-B-B4). Eleven mice received no treatment. Bioluminescence imaging and survival were assessed. Alpha-RIT 7.4 MBq and 11.1 MBq significantly improved survival (p = 0.0303 and p = 0.0070, respectively), whereas HIPEC and HIPEC + alpha-RIT treatments did not significantly ameliorate survival as compared to the control group. Survival was significantly increased by alpha-RIT treatment in mice with peritoneal carcinomatosis of ovarian origin; however, HIPEC alone or in combination with alpha-RIT had no significant effect.

A young woman was referred to us for the management of an umbilical hernia with macerated overlying skin through which massive ascites was leaking. On examination we found a jelly-like substance seeping out of the opening. A contrast-enhanced CT scan of the abdomen revealed bilateral ovarian cystadenocarcinoma with pseudomyxoma peritonei. The patient underwent cytoreductive surgery along with hysterectomy and bilateral oophorectomy followed by hyperthermic intraperitoneal chemotherapy with mitomycin C. Histopathological examination showed bilateral borderline cystadenoma with peritoneal adenomucinosis. Follow-up at 1 year showed no signs of recurrence. PMID:24855082

Local control is a major challenge in treating canine nasal tumours. Surgical cytoreduction prior to radiation therapy has not been shown to offer a survival advantage. Only one study has previously evaluated the outcome when surgery is performed after radiation, which demonstrated an improved survival time compared with radiation alone. The purpose of this study was to investigate the outcome of surgery after definitive radiation on survival times in dogs with sinonasal tumours. Medical records were retrospectively reviewed for dogs with nasal tumours that received definitive radiation followed by surgery. Information obtained from medical record review included signalment, diagnosis, treatment and outcome. The median survival time was 457 days. No long-term side effects were observed. These findings suggest that exenteration of the nasal cavity following definitive radiation for treatment of dogs with nasal tumours is well-tolerated and provides a similar survival duration to previous reports of radiation alone. © 2014 John Wiley & Sons Ltd.

To test whether the combination of number and location of distant metastases affects cancer-specific survival in patients with metastatic renal cell carcinoma. Overall, 242 metastatic renal cell carcinoma patients with synchronous metastases at diagnosis underwent cytoreductive nephrectomy at a single institution. Combinations of number and location of distant metastases were coded as: single metastasis and single organ affected, multiple metastases and single organ affected, single metastasis for each of the multiple organs affected, and multiple metastases for each of the multiple organs affected. Covariates included age, symptoms, performance status, American Society of Anesthesiologists score, hemoglobin, lactate dehydrogenase, tumor size, Fuhrman grade, T stage, lymph node status, necrosis, sarcomatoid features and metastasectomy at the time of nephrectomy. The median survival was 34.7 versus 32.3 versus 29.6 versus 8.5 months for single metastasis and single organ affected, multiple metastases and single organ affected single metastasis for each of the multiple organs affected, and multiple metastases for each of the multiple organs affected patients, respectively. At multivariable analyses, the combination of number and location of distant metastases resulted in one of the most informative and independent predictors of cancer-specific survival in metastatic renal cell carcinoma patients. The lung was the location with the highest rate of single organ affected (50.3% vs 35.1% in other sites; P < 0.001). Considering only patients with a single metastasis, no statistically significantly different cancer-specific survival rates were recorded (P > 0.3) among different metastatic organs. Among metastatic renal cell carcinoma patients undergoing cytoreductive nephrectomy, the combination of the number and location of distant metastases is a major independent predictor of cancer-specific survival. Patients with multiple organs affected by multifocal disease are more likely to have poorer survival. © 2012 The Japanese Urological Association.

Complete cytoreductive surgery (CCRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) is on the verge of becoming the gold standard treatment for selected patients presenting peritoneal metastases (PM) of colorectal origin. PM is scored with the peritoneal cancer index (PCI), which is the main prognostic factor. However, small bowel (SB) involvement could exert an independent prognostic impact. To define an adequate cut-off for the PCI and to appraise whether SB involvement exerts an impact on this cut-off. Patients (n = 139) treated with CCRS plus HIPEC were prospectively verified and retrospectively analyzed. One hundred presented with SB involvement of different extents and at different locations. All the patients with a PCI ≥ 15 exhibited SB involvement. Five-year overall survival was 48% when the PCI was <15 vs 12% when it was ≥ 15 (p < 0.0001. The multivariate analysis retained two prognostic factors: PCI ≥ 15 (p = 0.02, HR = 1.8), and the involvement of area 12 (lower ileum) (p = 0.001, HR = 3.1). When area 12 was invaded, it significantly worsened the prognosis: 5-year overall survival of patients with a PCI <15 and area 12 involved was 15%, close to that of patients with a PCI ≥ 15 (12%) and far lower than that of patients with a PCI <15 and no area 12 involvement (70%). A PCI greater than 15 appears to be a relative contraindication for treatment of colorectal PM with CCRS + HIPEC. Involvement of the lower ileum is also a negative prognostic factor to be taken into consideration. Copyright © 2014. Published by Elsevier Ltd.

Ovarian cancer is the most common deadly cancer of gynecologic origin. Patients often are diagnosed at advanced stage with peritoneal metastasis. There are many rare histologies of ovarian cancer; some have outcomes worse than serous ovarian cancer. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) can be considered for patients with recurrence. This study was designed to assess the impact of CRS and HIPEC on survival of patient with peritoneal metastasis from rare ovarian malignancy. A prospective, multicentric, international database was retrospectively searched to identify all patients with rare ovarian tumor (mucinous, clear cells, endometrioid, small cell hypercalcemic, and other) and peritoneal metastasis who underwent CRS and HIPEC through the Peritoneal Surface Oncology Group International (PSOGI) and BIG-RENAPE working group. The postoperative complications, long-term results, and principal prognostic factors were analyzed. The analysis included 210 patients with a median follow-up of 43.5 months. Median overall survival (OS) was 69.3 months, and the 5-year OS was 57.7%. For mucinous tumors, median OS and DFS were not reached at 5 years. For granulosa tumors, median overall survival was not reached at 5 years, and median DFS was 34.6 months. Teratoma or germinal tumor showed median overall survival and DFS that were not reached at 5 years. Differences in OS were not statistically significant between histologies (p = 0.383), whereas differences in DFS were (p < 0.001). CRS and HIPEC may increases long-term survival in selected patients with peritoneal metastasis from rare ovarian tumors especially in mucinous, granulosa, or teratoma histological subtypes.

A current challenge in the treatment of peritoneal carcinomatosis is the inability to detect, visualize, and resect small or microscopic tumors of pancreatic, ovarian, or mesothelial origin. In these diseases, the completeness of primary tumor resection is directly correlated with patient survival, and hence, identifying small sub-millimeter tumors (i.e., disseminated disease) is critical. Thus, new imaging techniques and probes are needed to improve cytoreductive surgery and patient outcomes. Highly fluorescent rhodamine-labeled expansile nanoparticles (HFR-eNPs) are described for use as a visual aid during cytoreductive surgery of pancreatic carcinomatosis. The covalent incorporation of rhodamine into ∼30 nm eNPs increases the fluorescent signal compared to free rhodamine, thereby affording a brighter and more effective probe than would be achieved by a single rhodamine molecule. Using the intraperitoneal route of administration, HFR-eNPs localize to regions of large (∼1 cm), sub-centimeter, and sub-millimeter intraperitoneal tumor in three different animal models, including pancreatic, mesothelioma, and ovarian carcinoma. Tumoral localization of the HFR-eNPs depends on both the material property (i.e., eNP polymer) as well as the surface chemistry (anionic surfactant vs PEGylated noncharged surfactant). In a rat model of pancreatic carcinomatosis, HFR-eNP identification of tumor is validated against gold-standard histopathological analysis to reveal that HFR-eNPs possess high specificity (99%) and sensitivity (92%) for tumors, in particular, sub-centimeter and microscopic sub-millimeter tumors, with an overall accuracy of 95%. Finally, as a proof-of-concept, HFR-eNPs are used to guide the resection of pancreatic tumors in a rat model of peritoneal carcinomatosis.

Cytoreductive surgery with heated intraperitoneal chemotherapy (CRS/HIPEC) often includes stoma creation. We evaluated the indications, morbidity, and mortality associated with stoma creation and reversal after CRS/HIPEC. Retrospective analysis of a prospective database of 1149 CRS-HIPEC procedures was performed. Patient demographics, type of malignancy, comorbidities, Clavien-graded morbidity, mortality, indications for stoma creation, and outcomes of subsequent reversal were abstracted. Sixteen percent (186/1149) of CRS/HIPEC procedures included stoma creation, whereas 1.1 % (11/963) of patients without initial stoma creation developed anastomotic leaks requiring stoma. Patients who required a stoma had worse preoperative performance status (ECOG 0/1: 77.2 vs. 86.1 %, p = 0.002), greater burden of disease (PCI 17.6 vs. 12.9, p < 0.0001), and were more likely to have R2 resections (74.5 vs. 48.8 %, p < 0.0001) than those without stoma creation. Stomas were intended to be permanent in 17.5 % (35/199). Of 164 patients with potentially reversible ostomies, only 26.2 % (43/164) underwent reversal. Disease progression (43/164, 26.2 %) and death (40/164, 24.3 %) most commonly precluded reversal. After reversal, 27.9 % (12/43) suffered a Clavien I/II morbidity, 27.9 % (12/43) suffered Clavien III/IV morbidity, and 30-day mortality was 4.7 % (2/43). Anastomotic leak occurred after 9 % (3/33) of ileostomy and 10 % (1/10) of colostomy reversals. Stomas are more common among CRS/HIPEC patients with a high burden of disease and poor functional status. Reversal is uncommon and is associated with significant major morbidity. Preoperative counseling for those with high disease burden and poor functional status should include the risk of permanent stoma.

Ovarian cancer quality measures are being developed to improve health care delivery and outcomes. Our objective is to evaluate compliance with 8 quality indicators proposed by the Society of Gynecologic Oncology. A review of 123 ovarian cancer patients who underwent primary surgical staging/cytoreduction and chemotherapy from 2010-2012 was undertaken. Medical records were reviewed, and descriptive statistics were performed to determine compliance. A timely operative report documenting residual disease was dictated for 121/123 (98.4%) patients. Complete surgical staging was performed in 33/55 (60.0%) stage I-IIIB patients, with lymphadenectomy most frequently omitted. For optimally debulked stage III patients, 52/56 (92.9%) were offered intraperitoneal chemotherapy. Ultimately, 29/56 (51.8%) received this route and 19/56 (33.9%) within 42 days (range 18-48, median 40 days). Clinical trial randomization and co-morbidities accounted for most cases of non-compliance. All 105 patients for whom chemotherapy was indicated received platin/taxane therapy, and 79/105 (75.2%) within 42 days (range 4-82, median 37days). Venous thromboembolism prophylaxis was provided mechanically in 122/123 (99.2%) and pharmacologically in 99/123 (80.5%) patients within 24h of surgery. Prophylactic parenteral antibiotics were administered within 60 min of cytoreduction in 119/123 (96.7%) and discontinued within 24h after surgery in 120/123 (97.6%) cases. Compliance with strict definitions of ovarian cancer quality indicators varies depending on the care delivered and documentation of that care. Increased attention to comprehensive surgical staging and timely initiation of chemotherapy appears warranted. With the move toward value-based payment models, quality indicators will play a significant role in health care delivery. Copyright © 2015 Elsevier Inc. All rights reserved.

Whether cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) is safe and worthwhile for elderly patients remains unclear. This meta-analysis of outcomes after CRS plus HIPEC for the elderly aimed to generate a higher level of evidence and precise indications for these patients. A systematic literature search for studies reporting postoperative outcomes after CRS plus HIPEC for elderly patients was performed in the MEDLINE, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, Web of Knowledge Conference Proceedings Citation Index-Science, and Google Scholar databases. The included studies evaluated the overall 30-day postoperative morbidity, 90-day postoperative mortality, grade 3 or higher postoperative morbidity, rates of anastomotic leaks, reoperation and readmission, and length of hospital stay. The inclusion criteria were met by 13 retrospective studies involving 2544 patients. Considering only comparative studies, the 90-day postoperative mortality was significantly increased for elderly patients [odds ratio (OR), 0.49; 95% confidence interval (CI), 0.27-0.88; I 2  = 79%]. The 30-day grade 3 or higher postoperative morbidity was increased in the patients 70 years of age or older (14.5%; 95% CI 8.1-24.4 vs. 32.3%; 95% CI 22.4-44.0%; p = 0.004; I 2  = 85%). The overall 30-day postoperative morbidity, rates of anastomotic leaks, reoperation and readmission, and length of hospital stay were not affected by age. Treatment of the elderly with CRS plus HIPEC was associated with increased severe postoperative morbidity and mortality. However, these conclusions should be weighted given the existence of major biases in the included studies. Age alone probably would not be a formal contraindication, but frailty should be taken into account. Further prospective studies are needed.

The aim of this study is to investigate the effect of first chromosome long arm duplication (dup(1q)) in cases with endometrial carcinoma detected with array based comperative genomic hybridization (aCGH) on survival from the cancer. A total of 53 patients with the diagnosis of endometrial carcinom due to endometrial biopsy and who have been operated for this reason have been allocated in the study. Frozen section biopsy and staging surgery have been performed for all the cases. Samples obtained from the tumoral mass have been investigated for chromosomal aberrations with aCGH method. Kaplan-Meier and Cox-regression analysis have been performed for survival analysis. Among 53 cases with endometrial carcinomas, dup(1q) was diagnosed in 14 (26.4%) of the cases. For the patient group that has been followed-up for 24 months (3-33 months), dup(1q) (p=.01), optimal cytoreduction (p<.001), lymph node positivity (p=.006), tumor stage >1 (p=.006) and presence of high risk tumor were the factors that were associated with survival. Cox-regression analysis has revealed that optimal cytoreduction was the most important prognostic factor (p=.02). Presence of 1q duplication can be used as a prognostic factor in the preoperative period.

Intraperitoneal chemotherapy together with cytoreductive surgery is the standard of care for a number of peritoneal surface malignancies. However, this approach fails to maintain the complete response and disease recurs due to microscopic residual disease. Although safer than systemic chemotherapy regimens, locoregional treatment with chemotherapeutics can induce toxicity which is a major concern affecting the patient’s treatment protocol and outcome. For an enhanced treatment efficacy, efforts should be made to maximize cytotoxic effects of chemotherapeutic agents on tumor cells while minimizing their toxic effects on host cells. Bromelain and N-acetylcysteine are two natural agents with good safety profiles shown to have anti-cancer effects. However, their interaction with chemotherapeutics is unknown. In this study, we investigated if these agents have the potential to sensitize in vitro gastrointestinal cancer models to cisplatin, paclitaxel, 5-fluorouracil, and vincristine. The drug-drug interaction was also analyzed. Our findings suggest that combination of bromelain and N-acetylcysteine with chemotherapeutic agents could give rise to an improved chemotherapeutic index in therapeutic approaches to peritoneal surface malignancies of gastrointestinal origin so that maximum benefits could result from less toxic and more patient-friendly doses. This represents a potentially efficacious strategy for the enhancement of microscopic cytoreduction and is a promising area for future research. PMID:27186409

Peritoneal Metastases from Gastrointestinal Cancer.

PubMed

Sugarbaker, Paul H

Peritoneal metastases may occur from a majority of cancers that occur within the abdomen or pelvis. When cancer spread to the peritoneal surfaces is documented, a decision regarding palliation vs. an aggressive approach using cytoreductive surgery (CRS) and perioperative intraperitoneal chemotherapy must be made. The perioperative chemotherapy may be hyperthermic intraperitoneal chemotherapy (HIPEC) administered in the operating room or early postoperative intraperitoneal chemotherapy (EPIC) administered in the first 4 or 5 postoperative days. This decision is dependent on a well-defined group of prognostic indicators. In addition to treatment, the clinical and pathologic features of a primary cancer can be used to select perioperative treatments that may prevent cancer cells within the abdomen and pelvis from progressing to established peritoneal metastases. In some clinical situations with appendiceal and colorectal cancers, the clinical or histopathologic features may indicate that second-look surgery plus perioperative chemotherapy should occur. Peritoneal metastases should always be considered for treatment or prevention.

Some recently developed concepts concerning the management of ovarian cancer are discussed. Cytoreductive surgery to debulk the tumor to a minimum, even in those cases which were considered inoperable in the past, improves the chances for cure. Adjuvant radiotherapy or combination chemotherapy with new drugs have proved highly effective in inducing complete remission and potential cures in these patients. The definition and better understanding of prognostic criteria play a primary role in the selection of treatment. In designing the strategy for adequate treatment, the following points are of major importance: (1) exact definition of tumor spread as determined by accurate surgical staging; (2) histologic and cytologic grading; and (3) evaluation of response.

The cytoreductive efficacy of the individual components of multidrug chemotherapy for canine lymphoma is difficult to evaluate after complete remission. To compare the cytoreductive efficacy of vincristine (VCR), cyclophosphamide (CPA), and doxorubicin (DXR) in dogs that received a 6-month modified version of the University of Wisconsin-Madison chemotherapy protocol (UW-25). Twenty-nine dogs with high-grade B-cell multicentric lymphoma. Rearranged immunoglobulin heavy chain gene fragments from lymphoma cells were amplified by polymerase chain reaction (PCR) and sequenced to prepare clone-specific primers and probes for real-time PCR. The number of lymphoma cells in peripheral blood was measured from diagnosis to week 11 of UW-25. The number of lymphoma cells after the 1st administration of VCR, CPA, and DXR in weeks 1-4 was decreased in 29/29 (100%), 15/29 (51.7%), and 26/27 (96.3%) dogs, respectively. The cytoreductive efficacy of CPA was less than that of VCR and DXR. VCR, CPA, and DXR administered in weeks 6-9 were effective in 5/26 (19.2%), 5/20 (25.0%), and 14/19 (73.7%) dogs, respectively, indicating the sustained cytoreductive efficacy of DXR. CPA nonresponders were heavier and exhibited a shorter 1st remission than CPA responders. When using UW-25 for treatment of canine lymphoma, CPA was found to have less cytoreductive efficacy than VCR and DXR. Real-time PCR-based quantification of tumor cells is an objective marker of the efficacy of chemotherapeutic agents. Copyright © 2011 by the American College of Veterinary Internal Medicine.

Bariatric surgery is effective in reducing all-cause and cause-specific long-term mortality. Whether the long-term mortality benefit of surgery applies to all ages at which surgery is performed is not known. To examine whether gastric bypass surgery is equally effective in reducing mortality in groups undergoing surgery at different ages. All-cause and cause-specific mortality rates and hazard ratios (HRs) were estimated from a retrospective cohort within 4 categories defined by age at surgery: younger than 35 years, 35 through 44 years, 45 through 54 years, and 55 through 74 years. Mean follow-up was 7.2 years. Patients undergoing gastric bypass surgery seen at a private surgical practice from January 1, 1984, through December 31, 2002, were studied. Data analysis was performed from June 12, 2013, to September 6, 2015. A cohort of 7925 patients undergoing gastric bypass surgery and 7925 group-matched, severely obese individuals who did not undergo surgery were identified through driver license records. Matching criteria included year of surgery to year of driver license application, sex, 5-year age groups, and 3 body mass index categories. Roux-en-Y gastric bypass surgery. All-cause and cause-specific mortality compared between those undergoing and not undergoing gastric bypass surgery using HRs. Among the 7925 patients who underwent gastric bypass surgery, the mean (SD) age at surgery was 39.5 (10.5) years, and the mean (SD) presurgical body mass index was 45.3 (7.4). Compared with 7925 matched individuals not undergoing surgery, adjusted all-cause mortality after gastric bypass surgery was significantly lower for patients 35 through 44 years old (HR, 0.54; 95% CI, 0.38-0.77), 45 through 54 years old (HR, 0.43; 95% CI, 0.30-0.62), and 55 through 74 years old (HR, 0.50; 95% CI, 0.31-0.79; P < .003 for all) but was not lower for those younger than 35 years (HR, 1.22; 95% CI, 0.82-1.81; P = .34). The lack of mortality benefit in those undergoing gastric bypass surgery at ages younger than 35 years primarily derived from a significantly higher number of externally caused deaths (HR, 2.53; 95% CI, 1.27-5.07; P = .009), particularly among women (HR, 3.08; 95% CI, 1.4-6.7; P = .005). Patients undergoing gastric bypass surgery had a significantly lower age-related increase in mortality than severely obese individuals not undergoing surgery (P = .001). Gastric bypass surgery was associated with improved long-term survival for all patients undergoing surgery at ages older than 35 years, with externally caused deaths only elevated in younger women. Gastric bypass surgery is protective against mortality even for older patients and also reduces the age-related increase in mortality observed in severely obese individuals not undergoing surgery.

Gastric cancer remains one of the most aggressive malignancies, being associated with very poor therapeutic outcomes, especially in the advanced disease patients. Due to this evidence, finding a better treatment, a better control and higher survival rates is the current scientific focus of the medical community. Once the benefits of cytoreductive surgery in association with intraperitoneal hyperthermy (HIPEC) have been widely demonstrated in patients presenting peritoneal carcinomatosis from colorectal or ovarian origin,attention was focused on the possible benefit of this method in patients diagnosed with peritoneal carcinomatosis with gastric origin. Moreover, using laparoscopy for the cytoreductive surgery (L-CRS) and hyperthermic intraperitoneal chemotherapy (L-HIPEC), the advantages of minimal invasive surgery (MIS) are expected to contribute to improved postoperative outcomes. In this way, the patients benefit from a faster administration of the adjuvant chemotherapeutic treatment, whenever is necessary. to present the technique of L-CRS + L-HIPEC and the early therapeutic outcomes in a case series of two patients diagnosed with peritoneal carcinomatosis from gastric cancer. A complete investigational work-up including diagnostic laparoscopy to evaluate the Peritoneal Carcinomatosis Index (PCI) was fulfilled in all the cases. The institutional Tumor Board decided the therapeutic strategy: laparoscopic radical resection and HIPEC (L-CRS +L-HIPEC). The procedures were performed into a private setting (Ponderas Academic Hospital). Results: Two male patients,46 and 69years old, presenting carcinomatosis from gastric cancer were included into the study. Initial PCI was assessed by laparoscopy and it was 18 and 7, respectively. Both cases underwent neoadjuvant chemotherapy. D2 laparoscopic radical gastrectomy and L-HIPEC was then performed. Time of procedure was360 and 320 minutes, respectively. The intraperitoneal temperature varied between 41 and 42°C, while the intra-esophageal temperature reached a maximum value of 37,7 °C. There was no perioperative or postoperative complication, nor mortality. The hospital stay was 8 days. Conclusions: Explorative laparoscopy can help select patients for conversion chemotherapy in the setting of high peritoneal carcinomatosis index (PCI) score. Laparoscopy radical excision + L-HIPEC were successfully performed with very good therapeutic outcomes. Celsius.

Metastasectomy is accepted as standard of care for selected patients with colorectal pulmonary metastases (CLM); however, the role of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for colorectal peritoneal metastases (CPM) is not universally accepted. We aim to compare oncological outcomes of patients with CLM and CPM after pulmonary resection and CRS-HIPEC, respectively, by comparing overall survival (OS) and disease-free survival (DFS). A retrospective review of 49 CLM patients who underwent pulmonary resection, and 52 CPM patients who underwent CRS-HIPEC in a single institution from January 2003 to March 2015, was performed. The 5-year OS for CLM patients and CPM patients were 59.6 and 40.5%, respectively (p = 0.100), while the 5-year DFS were 24.0 and 14.2%, respectively (p = 0.173). CPM patients had longer median operative time (8.38 vs. 1.75 h, p < 0.001), median hospital stay (13 vs. 5 days, p < 0.001), a higher rate of intensive care unit (ICU) admissions (67.3 vs. 8.2%, p < 0.001), and a higher rate of high-grade complications (17.3 vs. 4.1%, p < 0.001). Multivariate analysis demonstrated that recurrent lung metastasis after metastasectomy was an independent prognostic factor for OS of CLM patients (OR = 0.045, 95%, CL 0.003-0.622, p = 0.021). There were no independent prognostic factors for OS in CPM patients by multivariate analysis. There were no independent prognostic factors for DFS in CLM patients by multivariate analysis, but peritoneal cancer index score, bladder involvement, and higher nodal stage at presentation of the initial malignancy were independent prognostic factors for DFS in CPM patients. OS and DFS for CPM patients after CRS and HIPEC are comparable to CLM patients after lung resection, although morbidity appears higher. The prognostic factors affecting survival after surgery are different between CPM and CLM patients and must be considered when selecting patients for metastasectomy.

Our study aimed to elucidate the role of Kisspeptin (KISS1) in tumor tissues of patients with epithelial ovarian cancer (EOC) and investigate the prognostic value of this biomarker.Forty EOC patients and 20 uterine fibroids female patients with healthy ovaries undergoing cytoreductive surgery between January 2010 and January 2014 in our hospital were enrolled in this study. KISS1 expression in tumor and normal tissues was detected. Correlations between clinic-pathologic variables and KISS1 expression in EOC tissues and the prognostic value of KISS1 for overall survival were evaluated.During the follow-up of 11.2 to 62.1 months, the overall survival rate and mean survival time were 28.9% (11/38) and 38.35 ± 2.84 months. Preoperative KISS1 mRNA was higher in tumor tissue than in normal tissue (P <0.001), and it was associated with histologic grade of tumor, surgical FIGO stage, metastasis, and residual tumor size (all P <0.05). Multivariate survival analysis indicated significant influence of residual tumor size (HR = 2.357, P = 0.039) and preoperative KISS1 mRNA (HR = 0.0001, P <0.001) on mean survival time. Patients with low KISS1 mRNA expression had shorter survival time than those with high expression (P = 0.001).Preoperative KISS1 mRNA was a potential prognostic biomarker for EOC, and high preoperative KISS1 expression indicated a favorable prognosis.

Introduction Next-generation sequencing and advances in ‘omics technology have rapidly increased our understanding of the molecular landscape of epithelial ovarian cancers. Areas covered Once characterized only by histologic appearance and clinical behavior, we now understand many of the molecular phenotypes that underlie the different ovarian cancer subtypes. While the current approach to treatment involves standard cytotoxic therapies after cytoreductive surgery for all ovarian cancers regardless of histologic or molecular characteristics, focus has shifted beyond a ‘one size fits all’ approach to ovarian cancer. Expert commentary Genomic profiling offers potentially ‘actionable’ opportunities for development of targeted therapies and a more individualized approach to treatment with concomitant improved outcomes and decreased toxicity.

Obesity: an endocrine tumor?

PubMed

Dizdar, Omer; Alyamaç, Evrim

2004-01-01

Obesity is one of the most common disorders in clinical practice. The prevalance of obesity has increased by more than 60% since 1990. Adipose tissue acts as an endocrine organ secreting many factors into the blood, known as adipokines, including leptin, adipsin, acylation-stimulating protein, adiponectin, etc. This article examines the hypothesis that obesity may be evaluated as an endocrine tumor, regarding its genetic basis, hyperplasia and hypertrophy of adipocytes, neovascularisation within the adipose tissue associated with growth, and beneficisal metabolic effects of surgical removal of excess adipose tissue by liposuction. Assuming obesity as an endocrine tumor may bring out new treatment modalities. Liposuction as "cytoreductive surgery", antiangiogenic teraphy or anti-neoplastic drugs may be important components of obesity treatment in future.

Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is an emerging curative treatment option for patients with peritoneal carcinomatosis. It has a long-term survival benefit but is associated with high rates of morbidity, ranging from 12 % to 65 %, mainly due to infectious complications. We sought to evaluate the clinical relevance of routine intraoperative bacteriological sampling following CRS/HIPEC. Between November 2010 and December 2014, every patients receiving CRS/HIPEC were included. Three samples were routinely collected from standardized locations for intraperitoneal rinsing liquid bacteriological analysis (RLBA) after completion of HIPEC. The clinical and surgical features, bacteriological results, and short-term outcomes were retrospectively reviewed. The overall mortality and morbidity rates were 5 and 45 %, respectively. Among the 75 included patients, 40 % (n = 30) had at least one positive bacterial culture. Risk factors for a positive culture were colorectal resection (adjusted hazard ratio [HR] = 3.072, 95 % CI 1.843-8.004; p = 0.009) and blood loss >1000 mL (HR = 4.272, 95 % CI 1.080-18.141; p = 0.031). Among 26 (35 %) patients with abdominal infectious complications, 13 (17 %) experienced isolated complications. A positive RLBA result was independently associated with abdominal infectious complications (HR = 5.108, 95 % CI 1.220-16.336; p = 0.024) and isolated abdominal infectious complications (HR = 4.199, 95 % CI 1.064-15.961; p = 0.04). Forty percent of the RLBA samples obtained following CRS/HIPEC tested positive for bacteria. Bacterial sampling of rinsing liquid should be systematically performed. An aggressive and immediate antibiotic strategy needs to be evaluated.

Background It is estimated that 37 % of the U.S. population is obese. It is unknown how obesity influences the operative and survival outcomes of cytoreductive surgery (CRS)/hyperthermic intraperitoneal chemotherapy (HIPEC) procedures. Methods A retrospective analysis of a prospective database of 1,000 procedures was performed. Type of malignancy, performance status, resection status, hospital and intensive care unit stay, comorbidities, morbidity, mortality, and survival were reviewed. Results A total of 246 patients with body mass index (BMI) of >30 kg/m2 underwent 272 CRS/HIPEC procedures. Ninety-five (38.6 %) were severely obese (BMI > 35 kg/m2). A total of 135 (49.6 %) procedures were performed for appendiceal and 60 (22.1 %) for colon cancer. Median follow-up was 52 months. Both major and minor morbidity were similar for obese and non-obese patients. The 30-day mortality rates for obese and nonobese patients were 1.5 and 2.5 %, respectively. Median intensive care unit and hospital stay were 1 and 9 days, regardless of BMI. The 30-day readmission rate was similar between obese and non-obese patients (24.8 vs. 19.4 %, p = 0.11). Median survival for low-grade appendiceal cancer (LGA) was 76 months for obese patients and 107 months for non-obese patients (p = 0.32). Survival was worse for severely obese patients (median survival 54 months) versus non-obese patients with LGA (p = 0.04). Survival was similar for obese and non-obese patients with peritoneal surface disease (PSD) from colon cancer or high-grade appendiceal cancer. Conclusions Obesity does not influence postoperative morbidity or mortality of patients with PSD, regardless of primary tumor. Severe obesity is associated with decreased long-term survival only in patients with LGA primary disease; however, application of CRS/HIPEC still offers meaningful prolongation of life. Obesity should not be considered a contraindication for CRS/HIPEC procedures. PMID:23800899

Research was conducted to gain insight into potential clients' decisions to undergo plastic surgery, their perception of benefits and risks, their judgment of outcomes, and their selection of a plastic surgeon. Semistructured, open-ended interviews were conducted with 60 people who expressed interest in plastic surgery. Qualitative analysis revealed their "mental models" regarding influences on their decision to undergo plastic surgery and their choice of a surgeon. Interview results were used to design a Web-based survey in which 644 individuals considering plastic surgery responded. The desire for change was the most direct motivator to undergo plastic surgery. Improvements to physical well-being were related to emotional and social benefits. When prompted about risks, participants mentioned physical, emotional, and social risks. Surgeon selection was a critical influence on decisions to undergo plastic surgery. Participants gave considerable weight to personal consultation and believed that finding the "right" plastic surgeon would minimize potential risks. Findings from the Web-based survey were similar to the mental models interviews in terms of benefit ratings but differed in risk ratings and surgeon selection criteria. The mental models interviews revealed that interview participants were thoughtful about their decision to undergo plastic surgery and focused on finding the right plastic surgeon.

Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is a treatment option in patients with carcinomatosis from high-grade appendiceal (HGA) primaries. It is unknown if there is a Peritoneal Carcinomatosis Index (PCI) upper limit above which a complete CRS/HIPEC does not assure long-term survival. Retrospective analysis from three centers was performed. The PCI was used to grade volume of of disease. Survival in relation to PCI was studied on patients with complete cytoreduction. Overall, 521 HGA patients underwent CRS/HIPEC from 1993 to 2015, with complete CRS being achieved in 50% (260/622). Mean PCI was 14.8 (standard deviation 8.7, range 0-36). Median survival for the complete CRS cohort was 6.1 years, while 5- and 10-year survival was 51.7% (standard error [SE] 4.6) and 36.1% (SE 6.3), respectively. Arbitrary cut-off PCI limits with 5-point splits (p = 0.63) were not predictive of a detrimental effect on survival as long as a complete CRS was achieved. A linear effect of the PCI on survival (p = 0.62) was not observed, and single-point PCI cohort splits within a PCI range of < 5 to > 10 were not predictive of survival for complete CRS patients. The PCI correlated with the ability to achieve a complete CRS, with a mean PCI of 14.7 (8.7) for completeness of cytoreduction (CC)0, 22.3 (7.8) for CC1 and 26.1 (9.5) for CC2/3 resections (p = 0.0001, hazard ratio 1.12, 95% confidence interval 1.09), with an HR of 1.15 for each 1-unit increase in the PCI score. Only 21% of the cohort achieved a complete CRS with a PCI ≥ 21. The PCI correlates with the ability to achieve a complete CRS in carcinomatosis from HGA. PCI is not associated with survival as long as a complete CRS can be achieved.

OBJECTIVE To determine factors affecting race speed in Swedish Standardbred horses undergoing surgery of the carpal flexor sheath (CFS), to investigate whether preoperative racing speed was associated with specific intraoperative findings and whether horses returned to racing, and to compare the performance of horses undergoing surgery of the CFS with that of age- and sex-matched control horses. ANIMALS 149 Swedish Standardbred trotters undergoing surgery of the CFS and 274 age- and sex-matched control horses. PROCEDURES Medical records of CFS horses were examined. Racing data for CFS and control horses were retrieved from official online records. Generalizing estimating equations were used to examine overall and presurgery racing speeds and the association of preoperative clinical and intraoperative findings with preoperative and postoperative speeds. Multivariable regression analysis was used to examine career earnings and number of career races. Kaplan-Meier survival analysis was used to compare career longevity between CFS and control horses. RESULTS CFS horses were significantly faster than control horses. The CFS horses that raced before surgery were slower as they approached the surgery date, but race speed increased after surgery. There were 124 of 137 (90.5%) CFS horses that raced after surgery. No intrathecal pathological findings were significantly associated with preoperative racing speed. Career longevity did not differ between CFS and control horses. CONCLUSIONS AND CLINICAL RELEVANCE Horses undergoing surgery of the CFS had a good prognosis to return to racing after surgery. Racing careers of horses undergoing surgery of the CFS were not significantly different from racing careers of control horses.

Drugs, doses, and durations of intraperitoneal chemotherapy: standardising HIPEC and EPIC for colorectal, appendiceal, gastric, ovarian peritoneal surface malignancies and peritoneal mesothelioma.

Peritoneal surface malignancy (PSM) is a common manifestation of digestive and gynaecologic malignancies alike. At present, patients with isolated PSM are treated with a combination therapy of cytoreductive surgery (CRS) and hyperthermic peroperative intraperitoneal chemotherapy (HIPEC). The combination of CRS and intraperitoneal (IP) chemotherapy should now be considered standard of care for PSM from appendiceal epithelial cancers, colorectal cancer and peritoneal mesothelioma. Although there is a near universal standardisation regarding the CRS, we are still lacking a much-needed standardisation amongst the various IP chemotherapy treatment modalities used today in clinical practice. Pharmacologic evidence should be generated to answer important questions raised by the myriad of variables associated with IP chemotherapy.

New approach to peritoneal surface malignancies

2010-01-01

Peritoneal surface malignancies (PSM) are a clinical entity with an unfavourable prognosis. They comprise peritoneal carcinomatosis, pseudomyxoma peritonei, and primitive tumors of the peritoneum. Because the treatment of PSM presents unique and challenging problems to the cancer clinician, many new approaches have been attempted in recent years. In the current and next issues of World Journal of Gastrointestinal Oncology, some international groups of researchers discuss the most important and innovative aspects of PSM treatment, with particular accuracy for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. In conclusion, because this new approach to PSM has a reputation for being based more on common sense than on experimental data, I hope that highlighting this topic can make a contribution to the treatment of this group of diseases.

Objective This study was designed to compare the effectiveness of granisetron plus dexamethasone for preventing postoperative nausea and vomiting (PONV) in patients undergoing laparoscopic surgery. Methods We searched the literature in the Cochrane Library, PubMed, EMBASE, and CNKI. Results In total, 11 randomized controlled trials were enrolled in this analysis. The meta-analysis showed that granisetron in combination with dexamethasone was significantly more effective than granisetron alone in preventing PONV in patients undergoing laparoscopy surgery. No significant differences in adverse reactions (dizziness and headache) were found in association with dexamethasone. Conclusion Granisetron in combination with dexamethasone was significantly more effective than granisetron alone in preventing PONV in patients undergoing laparoscopic surgery, with no difference in adverse reactions between the two groups. Granisetron alone or granisetron plus dexamethasone can be used to prevent PONV in patients undergoing laparoscopic surgery. PMID:28436248

The ability to provide accurate prognostic and predictive information to patients is becoming increasingly important as clinicians enter an era of personalized medicine. For a disease as heterogeneous as epithelial ovarian cancer, conventional algorithms become too complex for routine clinical use. This study therefore investigated the potential for an artificial intelligence model to provide this information and compared it with conventional statistical approaches. The authors created a database comprising 668 cases of epithelial ovarian cancer during a 10-year period and collected data routinely available in a clinical environment. They also collected survival data for all the patients, then constructed an artificial intelligence model capable of comparing a variety of algorithms and classifiers alongside conventional statistical approaches such as logistic regression. The model was used to predict overall survival and demonstrated that an artificial neural network (ANN) algorithm was capable of predicting survival with high accuracy (93 %) and an area under the curve (AUC) of 0.74 and that this outperformed logistic regression. The model also was used to predict the outcome of surgery and again showed that ANN could predict outcome (complete/optimal cytoreduction vs. suboptimal cytoreduction) with 77 % accuracy and an AUC of 0.73. These data are encouraging and demonstrate that artificial intelligence systems may have a role in providing prognostic and predictive data for patients. The performance of these systems likely will improve with increasing data set size, and this needs further investigation.

Context This article discusses the anesthetic considerations in patients undergoing bariatric surgery in the preoperative, intraoperative, and postoperative phases of surgery. Evidence Acquisition This review includes studies involving obese patients undergoing bariatric surgery. Searches have been conducted in PubMed, MEDLINE, EMBASE, Google Scholar, Scopus, and Cochrane Database of Systematic Review using the terms obese, obesity, bariatric, anesthesia, perioperative, preoperative, perioperative, postoperative, and their combinations. Results Obesity is a major worldwide health problem associated with many comorbidities. Bariatric surgery has been proposed as the best alternative treatment for extreme obese patients when all other therapeutic options have failed. Conclusions Anesthetists must completely assess the patients before the surgery to identify anesthesia- related potential risk factors and prepare for management during the surgery. PMID:29430407

Immune function, pain, and psychological stress in patients undergoing spinal surgery.

This study was an exploratory repeated measures design comparing patients undergoing two magnitudes of surgery in the lumbar spine: lumbar herniated disc repair and posterior lumbar fusion. The present study evaluated and compared the effect of perceived pain, perceived stress, anxiety, and mood on natural killer cell activity (NKCA) and IL-6 production among adult patients undergoing lumbar surgery. Presurgical stress and anxiety can lead to detrimental patient outcomes after surgery, such as increased infection rates. It has been hypothesized that such outcomes are due to stress-immune alterations, which may be further exacerbated by the extent of surgery. However, psychologic stress, anxiety, and mood have not been previously characterized in patients undergoing spinal surgery. Pain, stress, anxiety, and mood were measured using self-report instruments at T1 (1 week before surgery), T2 (the day of surgery), T3 (the day after surgery), and T4 (6 weeks after surgery). Blood (30 mL) was collected for immune assessments at each time point. Pain, stress, anxiety, and mood state were elevated at baseline in both surgical groups and were associated with significant reduction in NKCA compared with the nonsurgical control group. A further decrease in NKCA was observed 24 hours after surgery in both surgical groups with a significant rise in stimulated IL-6 production, regardless of the magnitude of surgery. In the recovery period, NKCA increased to or above baseline values, which correlated with decreased levels of reported pain, perceived stress, anxiety, and mood state. This study demonstrated that patients undergoing elective spinal surgery are highly stressed and anxious, regardless of the magnitude of surgery and that such psychologic factors may mediate a reduction in NKCA.

As bariatric surgery rates continue to climb, anaemia will become an increasing concern. We assessed the prevalence of anaemia and length of hospital stay in patients undergoing bariatric surgery. Prospective data (anaemia [haemoglobin <12 g/dL], haematinics and length of hospital stay) was analysed on 400 hundred patients undergoing elective laparoscopic bariatric surgery. Results from a prospective database of 1530 patients undergoing elective general surgery were used as a baseline. Fifty-seven patients (14%) were anaemic pre-operatively, of which 98% were females. Median MCV (fL) and overall median ferritin (μg/L) was lower in anaemic patients (83 vs. 86, p=0.001) and (28 vs. 61, p<0.0001) respectively. In the elective general surgery patients, prevalence of anaemia was similar (14% vs. 16%) but absolute iron deficiency was more common in those undergoing bariatric surgery; microcytosis p<0.0001, ferritin <30 p<0.0001. Mean length of stay (days) was increased in the anaemic compared to in the non-anaemic group (2.7 vs. 1.9) and patients who were anaemic immediately post-operatively, also had an increased length of stay (2.7 vs. 1.9), p<0.05. Absolute iron deficiency was more common in patients undergoing bariatric surgery. In bariatric patients with anaemia there was an overall increased length of hospital stay.

Actigraphy for Measurement of Sleep and Sleep-Wake Rhythms in Relation to Surgery

PubMed Central

Madsen, Michael T.; Rosenberg, Jacob; Gögenur, Ismail

2013-01-01

Study Objectives: Patients undergoing surgery have severe sleep and sleep-wake rhythm disturbances resulting in increased morbidity. Actigraphy is a tool that can be used to quantify these disturbances. The aim of this manuscript was to present the literature where actigraphy has been used to measure sleep and sleep-wake rhythms in relation to surgery. Methods: A systematic review was performed in 3 databases (Medline, Embase, and Psycinfo), including all literature until July 2012. Results: Thirty-two studies were included in the review. Actigraphy could demonstrate that total sleep time and sleep efficiency was reduced after surgery and number of awakenings was increased in patients undergoing major surgery. Disturbances were less severe in patients undergoing minor surgery. Actigraphy could be used to differentiate between delirious and non-delirious patients after major surgery. Actigraphy measurements could determine a differential effect of surgery based on the patient's age. The effect of pharmacological interventions (chronobiotics and hypnotics) in surgical patients could also be demonstrated by actigraphy. Conclusion: Actigraphy can be used to measure sleep and sleep-wake rhythms in patients undergoing surgery. Citation: Madsen MT; Rosenberg J; Gögenur I.

Cardiac surgery may account for complications such as cognitive impairment, depression, and delay of convalescence. This study investigated the influence of different risk factors on cognitive performance, emotional state, and convalescence. We included 83 patients undergoing cardiac surgery who had no indication of postoperative delirium. Psychometric testing was performed 1 day before and 7 days after surgery. Neuron-specific enolase (NSE) levels were measured 1 day before and 36 h after surgery. Depression score increased after surgery, but patients showed no clinically significant depression. Postoperative cognitive performance correlated with postoperative depression level and preoperative cognitive performance. Forty-three percent of patients showed postoperative decline. Older patients exhibited a higher postoperative increase in NSE concentrations. Patients undergoing coronary artery bypass grafts or combined procedures exhibited more medical risk factors than those undergoing valve surgery alone. The number of bypass grafts was associated with time of hospitalization, and the number of patient-related risk factors correlated with stay in intensive care unit. For elderly patients undergoing cardiac surgery, older age, total preexisting medical risk factors, and surgery duration seem to be the most important factors influencing cognitive outcome and convalescence. Results show that, also for patients without postoperative delirium, medical risk factors and intraoperative parameters can result in delay of convalescence.

Background Diverticular disease of the colon is frequent in clinical practice, and a large number of patients each year undergo surgical procedures worldwide for their symptoms. Thus, there is a need for better knowledge of the basic pathophysiologic mechanisms of this disease entity. Objectives Because patients with colonic diverticular disease have been shown to display abnormalities of the enteric nervous system, we assessed the frequency of myenteric plexitis (i.e. the infiltration of myenteric ganglions by inflammatory cells) in patients undergoing surgery for this condition. Methods We analyzed archival resection samples from the proximal resection margins of 165 patients undergoing left hemicolectomy (60 emergency and 105 elective surgeries) for colonic diverticulitis, by histology and immunochemistry. Results Overall, plexitis was present in almost 40% of patients. It was subdivided into an eosinophilic (48%) and a lymphocytic (52%) subtype. Plexitis was more frequent in younger patients; and it was more frequent in those undergoing emergency surgery (50%), compared to elective (28%) surgery (p = 0.007). All the severe cases of plexitis displayed the lymphocytic subtype. Conclusions In conclusion, myenteric plexitis is frequent in patients with colonic diverticular disease needing surgery, and it might be implicated in the pathogenesis of the disease. PMID:26668745

Megavoltage radiation therapy currently is the standard of care for dogs with nasal tumors. Some studies report that surgery and adjunctive orthovoltage radiation therapy result in longer control of these tumors than does megavoltage radiation therapy alone. This study reports less effective control of nasal tumors in dogs treated with surgery and orthovoltage radiation than previously observed, supporting the superiority of megavoltage radiation therapy for these tumors. In addition, this study suggests 2 new prognostic indicators for dogs with nasal tumors and describes toxicity associated with surgery and orthovoltage therapy. Forty-two dogs with nasal tumors were treated with surgical cytoreduction and 48 Gy orthovoltage radiation therapy administered in twelve 4-Gy fractions. Median survival was 7.4 months. One- and 2-year survival rates were 37% and 17%, respectively. Dogs with facial deformity had shorter survival than those without deformity (P = .005). Dogs with resolution of clinical signs after treatment had longer survival than those with chronic nasal signs (P = .0001). Acute radiation toxicity was moderate to severe for skin and eye and negligible for oral mucosa. Toxicity healed within 1 month after radiation therapy. Late toxicity was mild, but 70% of evaluable dogs experienced persistent ocular signs. Only 39% of dogs achieved a disease-free period.

Essential thrombocythemia can be complicated by life-threatening thrombosis with a risk of converting into acute leukemia. Cytoreductive therapy may reduce the risk of thromboembolic complications. We usually recommend cytoreductive treatment for asymptomatic adult patients with platelet counts of more than 1.5 million/micro liter, but treatment remains obscure in children. Herein, we report the results of child with ET, treated successfully with hydroxuea.

Bariatric surgery has been shown to be the most effective method of achieving weight loss and alleviating obesity-related comorbidities. Yet, it is not being used equitably. This study seeks to identify if there is a disparity in payer status of patients undergoing bariatric surgery and what factors are associated with this disparity. We performed a case-control analysis of National Inpatient Sample. We identified adults with body mass index (BMI) greater than or equal to 25 kg/m 2 who underwent bariatric surgery and matched them with overweight inpatient adult controls not undergoing surgery. The sample was analyzed using multivariate logistic regression. We identified 132,342 cases, in which the majority had private insurance (72.8%). Bariatric patients were significantly more likely to be privately insured than any other payer status; Medicare- and Medicaid-covered patients accounted for a low percentage of cases (Medicare 5.1%, OR 0.33, 95% CI 0.29-0.37, p < 0.001; Medicaid 8.7%, OR 0.21, 95% CI 0.18-0.25, p < 0.001). Medicare (OR 1.54, 95% CI 1.33-1.78, p < 0.001) and Medicaid (OR 1.31, 95% CI 1.08-1.60, p = 0.007) patients undergoing bariatric surgery had an increased risk of complications compared to privately insured patients. Publicly insured patients are significantly less likely to undergo bariatric surgery. As a group, these patients experience higher rates of obesity and related complications and thus are most in need of bariatric surgery.

Cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy improves survival of gastric cancer with peritoneal carcinomatosis: evidence from an experimental study

PubMed Central

2011-01-01

Background Cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) has been considered as a promising treatment modality for gastric cancer with peritoneal carcinomatosis (PC). However, there have also been many debates regarding the efficacy and safety of this new approach. Results from experimental animal model study could help provide reliable information. This study was to investigate the safety and efficacy of CRS + HIPEC to treat gastric cancer with PC in a rabbit model. Methods VX2 tumor cells were injected into the gastric submucosa of 42 male New Zealand rabbits using a laparotomic implantation technique, to construct rabbit model of gastric cancer with PC. The rabbits were randomized into control group (n = 14), CRS alone group (n = 14) and CRS + HIPEC group (n = 14). The control group was observed for natural course of disease progression. Treatments were started on day 9 after tumor cells inoculation, including maximal removal of tumor nodules in CRS alone group, and maximal CRS plus heperthermic intraperitoneal chemoperfusion with docetaxel (10 mg/rabbit) and carboplatin (40 mg/rabbit) at 42.0 ± 0.5°C for 30 min in CRS + HIPEC group. The primary endpoint was overall survival (OS). The secondary endpoints were body weight, biochemistry, major organ functions and serious adverse events (SAE). Results Rabbit model of gastric cancer with PC was successfully established in all animals. The clinicopathological features of the model were similar to human gastric PC. The median OS was 24.0 d (95% confidence interval 21.8 - 26.2 d ) in the control group, 25.0 d (95% CI 21.3 - 28.7 d ) in CRS group, and 40.0 d (95% CI 34.6 - 45.4 d ) in CRS + HIPEC group (P = 0.00, log rank test). Compared with CRS only or control group, CRS + HIPEC could extend the OS by at least 15 d (60%). At the baseline, on the day of surgery and on day 8 after surgery, the peripheral blood cells counts, liver and kidney functions, and biochemistry parameters were all comparable. SAE occurred in 0 animal in control group, 2 animals in CRS alone group including 1 animal death due to anesthesia overdose and another death due to postoperative hemorrhage, and 3 animals in CRS + HIPEC group including 1 animal death due to anesthesia overdose, and 2 animal deaths due to diarrhea 23 and 27 d after operation. Conclusions In this rabbit model of gastric cancer with PC, CRS alone could not bring benefit while CRS + HIPEC with docetaxel and carboplatin could significantly prolong the survival with acceptable safety.

The objective of this study was to assess the impact of robotic approaches on outcomes of coronary bypass surgery. Retrospective national database analysis. United States hospitals. A weighted sample of 484,128 patients undergoing isolated coronary artery surgery identified from the Nationwide Inpatient Sample from 2008 through 2010. Robotically assisted coronary artery bypass surgery versus conventional bypass surgery. Robotic approaches were used in 2,582 patients (0.4%). Patients undergoing robotic surgery were less likely to be female (odds ratio [OR] 0.71, 95% confidence interval [CI] 0.57-0.87), present with acute myocardial infarction (OR 0.53, 95% CI 0.38-0.73), or have cerebrovascular disease (OR 0.41, 95% CI 0.23-0.71) compared to patients undergoing conventional surgery. In 59% of robotic cases, a single bypass was performed, and 2 bypasses were performed in 25% of cases. After adjusting for comorbidity, reduced postoperative stroke (0.0% v 1.5%, p = 0.045) and transfusion (13.5% v 24.4%, p = 0.001) rates were observed in patients who underwent robotic single-bypass surgery compared to conventional surgery. In patients undergoing multiple bypass grafts, higher mortality (1.1% v 0.5%), and cardiovascular complications (12.2% v 10.6%) were observed when robotic assistance was used, but the differences were not statistically significant (p = 0.5). The mean number of robotic cases carried out annually at institutions sampled was 6. Robotic assistance is associated with lower rates of postoperative complications in highly selected patients undergoing single coronary artery bypass surgery, but the benefits of this approach are reduced in patients who require multiple coronary artery bypass grafts.

The Society of Thoracic Surgeons 2008 cardiac surgery risk models have been developed for heart valve surgery with and without coronary artery bypass grafting. The aim of our study was to evaluate the performance of Society of Thoracic Surgeons 2008 cardiac risk models in Chinese patients undergoing single valve surgery and the predicted mortality rates of those undergoing multiple valve surgery derived from the Society of Thoracic Surgeons 2008 risk models. A total of 12,170 patients underwent heart valve surgery from January 2008 to December 2011. Combined congenital heart surgery and aortal surgery cases were excluded. A relatively small number of valve surgery combinations were excluded. The final research population included the following isolated heart valve surgery types: aortic valve replacement, mitral valve replacement, and mitral valve repair. The following combined valve surgery types were included: mitral valve replacement plus tricuspid valve repair, mitral valve replacement plus aortic valve replacement, and mitral valve replacement plus aortic valve replacement and tricuspid valve repair. Evaluation was performed by using the Hosmer-Lemeshow test and C-statistics. Data from 9846 patients were analyzed. The Society of Thoracic Surgeons 2008 cardiac risk models showed reasonable discrimination and poor calibration (C-statistic, 0.712; P = .00006 in Hosmer-Lemeshow test). Society of Thoracic Surgeons 2008 models had better discrimination (C-statistic, 0.734) and calibration (P = .5805) in patients undergoing isolated valve surgery than in patients undergoing multiple valve surgery (C-statistic, 0.694; P = .00002 in Hosmer-Lemeshow test). Estimates derived from the Society of Thoracic Surgeons 2008 models exceeded the mortality rates of multiple valve surgery (observed/expected ratios of 1.44 for multiple valve surgery and 1.17 for single valve surgery). The Society of Thoracic Surgeons 2008 cardiac surgery risk models performed well when predicting the mortality for Chinese patients undergoing valve surgery. The Society of Thoracic Surgeons 2008 models were suitable for single valve surgery in a Chinese population; estimates of mortality for multiple valve surgery derived from the Society of Thoracic Surgeons 2008 models were less accurate.

This study summarises the results of a National Audit of sino-nasal surgery carried out in England and Wales. It describes patient and operative characteristics as well as patient outcomes up to 36 months after surgery. Prospective cohort study. NHS hospitals in England and Wales. Consecutive patients undergoing surgery for nasal polyposis and/or chronic rhinosinusitis. The total score derived from a 22-item version of the Sino-Nasal Outcome Test (SNOT-22). Lower scores represent better health-related quality of life. A total of 3128 consecutive patients at 87 NHS hospitals were enrolled. There is a large improvement in SNOT-22 scores from the pre-operative period (mean = 42.0) to 3 months after surgery (mean = 25.5). The scores for patients undergoing nasal polypectomy improved from 41.0 before surgery to 23.1 at 3 months after surgery, while the scores for patients undergoing surgery for chronic rhinosinusitis alone improved from 44.2 to 31.2. The SNOT-22 scores reported at 12 and 36 months after surgery were similar to those reported at 3 months. Excessive bleeding occurred in 5% of patients during the operation and in 1% of patients after the operation. Intra-orbital complications were reported in 0.2%. Of those patients undergoing primary surgery for bilateral grade I or II polyposis, 18% had not received a pre-operative course of steroid treatment. At the 36-month follow-up, 11.4% of patients had undergone revision surgery. The audit confirms that sino-nasal surgery is generally safe and effective. There is some evidence that patient selection for surgery could be improved.

Risk of iron overload is decreased in beating heart coronary artery surgery compared to conventional bypass.

Conventional cardiopulmonary bypass surgery (CCPB) increases the iron loading of plasma transferrin often to a state of plasma iron overload, with the presence of low molecular mass iron. Such iron is a potential risk factor for oxidative stress and microbial virulence. Here we assess 'off-pump' coronary artery surgery on the beating heart for changes in plasma iron chemistry. Seventeen patients undergoing cardiac surgery using the 'Octopus' myocardial wall stabilisation device were monitored at five time points for changes in plasma iron chemistry. This group was further divided into those (n=9) who had one- or two- (n=8) vessel grafts, and compared with eight patients undergoing conventional coronary artery surgery. Patients undergoing beating heart surgery had significantly lower levels of total plasma non-haem iron, and a decreased percentage saturation of their transferrin at all time points compared to conventional bypass patients. Plasma iron overload occurred in only one patient undergoing CCPB. Beating heart surgery appears to decrease red blood cell haemolysis, and tissue damage during the operative procedures and thereby significantly decreases the risk of plasma iron overload associated with conventional bypass.

Bone marrow transplantation (BMT) for class 3 patients with thalassemia is challenging due to high rates of graft rejection and transplant-related mortality. Since the first studies of BMT in the late 1980s, a number of conditioning regimens have been designed to improve outcomes, but with suboptimal results. Here we report the outcome of transplantation in class 3 patients using a modified protocol. Sixty-three patients between 5 and 16.7 years of age with class 3 thalassemia received HLA-matched sibling BMT following either the original protocol (26 patients) or the modified protocol (37 patients). Both regimens comprised preconditioning cytoreduction with hydroxyurea and azathioprine starting at -45 days pretransplant, and fludarabine from days -16 to -12. Conditioning was performed with busulfan and cyclophosphamide (original protocol) or with busulfan, thiotepa, and cyclophosphamide (modified protocol). The 2 groups showed similar patient demographics. At day 0, the degree of cytoreduction (lymphopenia, neuthropenia, and thrombocytopenia) achieved by the modified protocol was greater than the original protocol. The incidence of graft failure/rejection was significantly higher in the original group (15%; 95% confidence interval [95% CI], 5-32%) compared with the modified group (0%) (P = 0.014). The respective 5-year thalassemia-free survival rates were 73% (95% CI, 51-86%) and 92% (95% CI, 77-97%) (P = 0.047). Both groups showed similar incidences of grades II to IV acute graft-versus host disease. Modified protocol did not increase nonhematological toxicity or infectious complications. The modified treatment protocol effectively and safely prevented graft failure/rejection and significantly increased thalassemia-free survival of class 3 patients with thalassemia.

Late-stage ovarian cancer patient's survival depends on complete cytoreduction and chemotherapy. Complete cytoreduction is more often achieved in institutions with a case volume of >20 cases per year. The Integrated care program Ovar (IgV Ovar) was founded in 2005 and started recruiting in 2006 with 21 health insurances and six expert centers of ovarian cancer treatment as a quality initiative. Results of the pilot and outcomes of patients of three participating centers will be presented here. Data of 1038 patients with ovarian cancer were collected. Adjuvant patients (n = 505) stage FIGO IIB-IV (n = 307) were analyzed for cytoreduction and survival. FIGO IIIC patients were analyzed separately. Median follow-up was 32.7 months. Progression-free survival (PFS) was 23.1 months and overall survival (OS) was 53.6 months for stage IIB-IV. Patients with FIGO IIIC were completely cytoreduced in 48 %. PFS was 21, 29 months if completely cytoreduced. OS was 47.4, 64.9 months if completely cytoreduced.D ISCUSSION: Although the IgV Ovar Rhineland proved to have some structural problems with recruitment and prospective data collection, cytoreduction rates and outcome of patients prove treatment of patients in expert centers is superior to the national and international mean. Therefore, a new quality initiative will be started to bring more awareness to women and to their gynecologists and general practitioners of just how important a good referral strategy is.

Epithelial ovarian cancer is the leading cause of death from gynaecologic cancers in the Western world. If possible, initial cytoreductive surgery is the treatment of choice, followed by adjuvant chemotherapy, usually with a platinum/taxane combination. Increased survival has been recently reported in women who were given adjuvant chemotherapy weekly rather than at three-week intervals, which has been the standard. At our centre, we have been treating patients with advanced ovarian cancer with a dose-dense protocol since March 2010. Treatment is given in an outpatient setting on days 1, 8, and 15 of a 21-day cycle for six cycles. Carboplatin for an AUC of 5 mg/mL/min and paclitaxel 80mg/m² are given on day 1, followed by paclitaxel 80mg/m² on days 8 and 15. Our objective was to determine whether this protocol is a feasible alternative treatment in our population and whether or not the toxicity profile is acceptable. We performed a chart review of 46 patients undergoing treatment with dose-dense chemotherapy for advanced ovarian cancer. Demographic information, patient characteristics, adverse events, and treatment endpoints were recorded. Sixty-one percent of women completed the six-cycle protocol as planned with minimal interruption, which is comparable to the only previously reported trial using this regimen. The most common side effects of treatment were fatigue, neuropathy, and neutropenia. Supplementation with regular magnesium and granulocyte colony-stimulating factor reduced delays. Dose-dense paclitaxel with carboplatin chemotherapy for the treatment of advanced ovarian cancer shows promise in terms of progression-free and overall survival. We have shown this protocol to be practical and feasible in our population.

Patient-reported outcomes (PRO) represent an important measure of cancer therapy effect. For patients with metastatic epidural spinal cord compression (MESCC), hybrid therapy using separation surgery and stereotactic radiosurgery preserves neurologic function and provides tumor control. There is currently a paucity of data reporting PRO after such combined modality therapy for MESCC. Delineation of hybrid surgery-radiosurgery therapy effect on PRO validates the hybrid approach as an effective therapy resulting in meaningful symptom relief. Brief Pain Inventory (BPI) and MD Anderson Symptom Inventory-Spine Tumor (MDASI-SP), PROs validated in the cancer population, were prospectively collected. Patients with MESCC who underwent separation surgery followed by stereotactic radiosurgery were included. Separation surgery included a posterolateral approach without extensive cytoreductive tumor excision. A median postoperative radiosurgery dose of 2700 cGy was delivered. The change in PRO 3 months after the hybrid therapy represented the primary study outcome. Preoperative and postoperative evaluations were analyzed using the Wilcoxon signed-rank test for matched pairs. One hundred eleven patients were included. Hybrid therapy resulted in a significant reduction in the BPI items "worst" and "right now" pain ( P < .0001), and in all BPI constructs (severity, interference with daily activities, and pain experience, P < .001). The MDASI-SP demonstrated reduction in spine-specific pain severity and interference with general activity ( P < .001), along with decreased symptom interference ( P < .001). Validated PRO instruments showed that in patients with MESCC, hybrid therapy with separation surgery and radiosurgery results in a significant decrease in pain severity and symptom interference. These prospective data confirm the benefit of hybrid therapy for treatment of MESCC and should facilitate referral of patients with MESCC for surgical evaluation.

Summary Statement Impaired olfaction, identified in 33% of patients undergoing cardiac surgery, was associated with the adjusted risk for postoperative delirium but not cognitive decline. Objectives The prevalence and significance of impaired olfaction is not well characterized in patients undergoing cardiac surgery. Because impaired olfaction has been associated with underlying neurologic disease, impaired olfaction may identify patients who are vulnerable to poor neurological outcomes in the perioperative period. The objective of this study was to determine the prevalence of impaired olfaction among patients presenting for cardiac surgery and the independent association of impaired olfaction with postoperative delirium and cognitive decline. Design Nested prospective cohort study Setting Academic hospital Participants 165 patients undergoing coronary artery bypass and/or valve surgery Measurements Olfaction was measured using the Brief Smell Identification Test, with impaired olfaction defined as an olfactory score < 5th percentile of normative data. Delirium was assessed using a validated chart-review method. Cognitive performance was assessed using a neuropsychological testing battery at baseline and 4–6 weeks after surgery. Results Impaired olfaction was identified in 54 of 165 patients (33%) prior to surgery. Impaired olfaction was associated with increased adjusted risk for postoperative delirium (relative risk [RR] 1.90, 95% CI 1.17–3.09; P=0.009). There was no association between impaired olfaction and change in composite cognitive score in the overall study population. Conclusion Impaired olfaction is prevalent in patients undergoing cardiac surgery and is associated with increased adjusted risk for postoperative delirium, but not cognitive decline. Impaired olfaction may identify unrecognized vulnerability for postoperative delirium among patients undergoing cardiac surgery. PMID:25597555

Abnormalities on magnetic resonance imaging scans are common both before and after surgery for congenital heart disease in early infancy. The aim of this study was to prospectively investigate the nature, timing, and consequences of brain injury on magnetic resonance imaging in a cohort of young infants undergoing surgery for congenital heart disease both with and without cardiopulmonary bypass. A total of 153 infants undergoing surgery for congenital heart disease at <8 weeks of age underwent serial magnetic resonance imaging scans before and after surgery and at 3 months of age, as well as neurodevelopmental assessment at 2 years of age. White matter injury (WMI) was the commonest type of injury both before and after surgery. It occurred in 20% of infants before surgery and was associated with a less mature brain. New WMI after surgery was present in 44% of infants and at similar rates after surgery with or without cardiopulmonary bypass. The most important association was diagnostic group (P<0.001). In infants having arch reconstruction, the use and duration of circulatory arrest were significantly associated with new WMI. New WMI was also associated with the duration of cardiopulmonary bypass, postoperative lactate level, brain maturity, and WMI before surgery. Brain immaturity but not brain injury was associated with impaired neurodevelopment at 2 years of age. New WMI is common after surgery for congenital heart disease and occurs at the same rate in infants undergoing surgery with and without cardiopulmonary bypass. New WMI is associated with diagnostic group and, in infants undergoing arch surgery, the use of circulatory arrest.

Our aim in this study was to assess the impact of the turnover of residents in July on patients undergoing pituitary surgery. This work was a retrospective cohort study of cases from the National Inpatient Sample (NIS). Patients who underwent pituitary surgery from 2005 to 2012 were selected in the NIS. Patients undergoing surgery in July and in non-July months were compared to determine differences in demographics, comorbidities, and complications. Of the 12,939 patients, 1098 (8.5%) underwent pituitary surgery in July. Patients receiving surgery in July had similar demographics and Agency for Healthcare Research and Quality comorbidity values compared with patients receiving surgery in other months. There were no significant differences in mortality, cerebral edema, cerebrospinal fluid leakage, iatrogenic pituitary complications, iatrogenic cerebrovascular accidents, urinary tract infections, pulmonary edema, pulmonary complications, or acute cardiac complications. There were no differences in the rate of postoperative fistulas, hematomas, perforations, or infections. The use of meningeal suturing, pedicled or free-flap reconstruction, and skin reconstruction was more frequent in July. Finally, hospitalization costs in July were similar to costs in other months. The turnover of new residents in July showed no change in complication rates for patients undergoing pituitary surgery. Patient care in July is similar to care during other months, demonstrating that hospitals are adequately supervising surgical residents during this transition. © 2018 ARS-AAOA, LLC.

The role of SC before CRS/HIPEC for patients with PMCA is unclear. This study explores the effect of SC prior to CRS/HIPEC on overall survival (OS) in patients with PMCA. 72 patients with recently diagnosed PMCA who underwent CRS/HIPEC were identified from a prospective database. Thirty patients had SC before CRS/HIPEC (Group 1) and 42 did not (Group 2). Patients who were referred to our center after multiple lines of SC were excluded from this analysis. OS was estimated. Median follow-up was 3.2 years. Groups were similar regarding lymph node positivity, postoperative SC and rate of complete cytoreduction. Twenty-four (80%) patients in Group 1 and 21 (50%) in Group 2 had high grade histology (HG) (p = 0.01). OS from CRS/HIPEC at 1, 2, and 3 years was 93, 68, 51% in Group 1 and 82, 64, 60% in Group 2, respectively (p = 0.74). Among HG patients 3-year survival was 36% in the SC group vs. 35% in the group without SC (p = 0.67). The 3-year OS for patients with low grade (LG) tumors was 100% in the SC group vs. 79% in the group with no prior SC (p = 0.26). Among patients with signet ring cell (SRC) histology, 1, 2 and 3-year survival was 94, 67 and 22% in the SC group vs. 43, 14, 14% in the group with no SC, respectively (p = 0.028). There were only 6 patients with LG PMCA who received prior SC. Preoperative SC could improve the prognosis of patients with high-grade PMCA with SRC histology. Copyright © 2015 Elsevier Ltd.

Peritoneal tumour dissemination is still considered as a terminal disease. For the last two decades, cytoreductive surgery (CRS) combined with intraoperative hyperthermic chemotherapy (HIPEC) has been popularised by Paul Sugarbaker almost doubling survival in selected patients compared with systemic chemotherapy alone. Nowadays, this particular treatment protocol is available in comprehensive cancer centres with reasonable mortality and morbidity. However, patient selection is still challenging. In general, CRS and HIPEC is indicated in primary peritoneal tumours such as mesothelioma and pseudomyxoma peritonei as well as in peritoneal metastases derived from gastrointestinal malignancies and ovarian cancers. Since systemic tumour spread is uncommon in patients with peritoneal metastases, peritoneal tumour dissemination was defined as localised disease within the "compartment abdomen". However, CRS and HIPEC are only beneficial as long as complete cytoreduction is achieved (CC-0 or CC-1). Histopathological parameters, the Sugarbaker peritoneal carcinomatosis index (PCI) and general condition of the patient have been established as patient selection criteria. In primary peritoneal cancers, individual tumour biology is the predominant criterium for patient selection as opposed to intraabdominal tumour load in peritoneal metastases derived from gastrointestinal cancers. In gastric cancer, CRS and HIPEC should be restricted to synchronous limited disease because of its biological aggressiveness. In patients with free floating cancer cells without macroscopic signs of peritoneal spread, however, CRS and HIPEC following preoperative "neoadjuvant" chemotherapy preserves chances for cure. So far, there is no general recommendation for CRS and HIPEC by clinical practice guidelines. In the recent S3 guideline for treatment of colorectal cancer, however, CRS and HIPEC have been included as possible treatment options. Georg Thieme Verlag KG Stuttgart · New York.

2017-01-01

Objectives Treatment options for patients with gastrointestinal cancer and oligometastastic disease remain the domain of the medical oncologist. However, in selected cases, attempts to remove or destroy the tumor burden seem appropriate. Background Data During the last decade, the treatment of localized and isolated tumor nodules, such as lung, liver or peritoneal metastasis, has changed. Previously, these patients with metastatic disease only received palliative chemotherapy. Combined treatment approaches and new techniques demonstrate that additional surgery to destroy or remove the metastases seem to be of major benefit to patients. Methods The recently published important literature regarding peritoneal metastases and oligometastases in gastrointestinal cancer was analyzed. Results The most important factor in the treatment of peritoneal metastases and in cytoreductive surgery is patient selection. Resection of peritoneal metastases should be considered. Hyperthermic intraperitoneal chemotherapy is feasible. However, further results of randomized trials are necessary. Several randomized trials are on the way and will be available in 1–2 years. Systemic chemotherapy alone as an adequate management plan for all sites of metastatic disease is not compatible with a high standard of care. Formulating an optimal plan combining re-operative surgery with regional plus systemic chemotherapy is a necessary task of the multidisciplinary team. Conclusions In oligometastastic disease of gastrointestinal cancer origin, the selection process is the most important factor for survival. Further studies are needed to determine optimal treatment options. PMID:28612016

Does intraoperative facial nerve monitoring during vestibular schwannoma surgery lead to better long-term facial nerve function? This recommendation applies to adult patients undergoing vestibular schwannoma surgery regardless of tumor characteristics. Level 3: It is recommended that intraoperative facial nerve monitoring be routinely utilized during vestibular schwannoma surgery to improve long-term facial nerve function. Can intraoperative facial nerve monitoring be used to accurately predict favorable long-term facial nerve function after vestibular schwannoma surgery? This recommendation applies to adult patients undergoing vestibular schwannoma surgery. Level 3: Intraoperative facial nerve can be used to accurately predict favorable long-term facial nerve function after vestibular schwannoma surgery. Specifically, the presence of favorable testing reliably portends a good long-term facial nerve outcome. However, the absence of favorable testing in the setting of an anatomically intact facial nerve does not reliably predict poor long-term function and therefore cannot be used to direct decision-making regarding the need for early reinnervation procedures. Does an anatomically intact facial nerve with poor electromyogram (EMG) electrical responses during intraoperative testing reliably predict poor long-term facial nerve function? This recommendation applies to adult patients undergoing vestibular schwannoma surgery. Level 3: Poor intraoperative EMG electrical response of the facial nerve should not be used as a reliable predictor of poor long-term facial nerve function. Should intraoperative eighth cranial nerve monitoring be used during vestibular schwannoma surgery? This recommendation applies to adult patients undergoing vestibular schwannoma surgery with measurable preoperative hearing levels and tumors smaller than 1.5 cm. Level 3: Intraoperative eighth cranial nerve monitoring should be used during vestibular schwannoma surgery when hearing preservation is attempted. Is direct monitoring of the eighth cranial nerve superior to the use of far-field auditory brain stem responses? This recommendation applies to adult patients undergoing vestibular schwannoma surgery with measurable preoperative hearing levels and tumors smaller than 1.5 cm. Level 3: There is insufficient evidence to make a definitive recommendation.  The full guideline can be found at: https://www.cns.org/guidelines/guidelines-manage-ment-patients-vestibular-schwannoma/chapter_4.

2015-08-01

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.

Primary fallopian tube carcinoma (PFTC) is a rare tumour of the female genital tract with an incidence of 0.1-1.8% of all genital malignancies, and it is very difficult to diagnose preoperatively, because of its non-specific symptomatology. In most cases, it is an intraoperative finding or a histopathological diagnosis. It is a tumour that histologically and clinically resembles epithelial ovarian cancer. We are reporting a case of a 62-year-old, postmenopausal women with primary fallopian tube carcinoma of the right fallopian tube in stage IA. The patient has lower abdominal pain, watery vaginal discharge and repeated episodes of bleeding from the vagina. The clinical and radiological findings suggested a right adnexal tumour with elevated CA-125 levels. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy and peritoneal washing were performed. Pathologic confirmation of primary serous cystadenocarcinoma of the right fallopian tube was made. Peritoneal washings were negative for malignancy. FIGO stage was considered as IA, and the patient received no courses of chemotherapy and postoperative radiation because she refused it. Ten months after initial surgery, the patient is alive and in good condition. Cytoreduction surgery followed by adequate cycles of chemotherapy is an important strategy to improve patients' prognosis.

To compare postoperative outcomes in children undergoing cardiac surgery during the viral respiratory season and nonviral season at our institution. This was a retrospective cohort study and secondary matched case-control analysis. The setting was an urban academic tertiary-care children's hospital. The study was comprised of all patients <18 years of age who underwent cardiac surgery at Johns Hopkins Hospital from October 2002 through September 2007. Patients were stratified by season of surgery, complexity of cardiac disease, and presence or absence of viral respiratory infection. Measurements included patient characteristics and postoperative outcomes. The primary outcome was postoperative length of stay (LOS). A total of 744 patients were included in the analysis. There was no difference in baseline characteristics or outcomes, specifically, no difference in postoperative LOS, intensive care unit (ICU) LOS, and mortality, among patients by seasons of surgery. Patients with viral respiratory illness were more likely to have longer postoperative LOS (p < 0.01) and ICU LOS (p < 0.01) compared with matched controls. We identified no difference in postoperative outcomes based on season in patients undergoing cardiac surgery. Children with viral respiratory infection have significantly worse outcomes than matched controls, strengthening the call for universal administration of influenza vaccination and palivizumab to appropriate groups. Preoperative testing for respiratory viruses should be considered during the winter months for children undergoing elective cardiac surgery.

To ascertain contemporary overall and differential thirty-day mortality (TDM) rates after all types of nephrectomy in the UK, and to identify potential new risk factors for death. We conducted a retrospective analysis of the 110 deaths that occurred within 30 days of surgery out of the total of 21 380 nephrectomies performed, and calculated the odds ratio (OR) and 95% confidence interval (CI) for TDM based on peri-operative characteristics. The overall TDM rate was 110/21380 (0.5%). The TDM rates after radical, partial, simple nephrectomy and nephro-ureterectomy were 0.6% (63/11057), 0.1% (4/3931), 0.4% (11/2819) and 0.9% (28/3091), respectively. TDM increased with age, stage, estimated blood loss (EBL), operating time and performance status. EBL of 1-2 L was associated with a greater risk of TDM than EBL of 2-5 L (OR 1.38; 95% CI 1.03-2.24). Conversion from minimally invasive surgery was associated with higher risk than non-conversion (OR 2.53; 95% CI 1.14-4.51. Curative surgery was safer than cytoreductive surgery (OR 0.31; 95% CI 0.18-0.54). There was an association between surgical volume and TDM. This study provides contemporary insights into the true risks of all types of nephrectomy. The TDM rate after nephrectomy in the UK appears acceptably low at 0.5%. Established risk factors were confirmed and the following novel risk factors were identified: modest EBL (1-2 L) and conversion from minimally invasive surgery. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

Peritoneal carcinomatosis (PC) is a cancer disease with an urgent need for effective treatment. Conventional chemotherapy failed to show acceptable results. Cytoreductive surgery and hyperthermic chemoperfusion (HIPEC) are only beneficial in few patients with resectable peritoneal metastasis. Immunotherapy could be attractive against PC, as all requirements for immunotherapy are available in the peritoneal cavity. This review analyzes the present literature for immunotherapy of PC. Advances from immune stimulators, radionucleotide-conjugated- and bispecific antibodies to future developments like adoptive engineered T-cells with chimeric receptors are discussed. The clinical development of catumaxomab, which was the first intraperitoneal immunotherapy to be approved for clinical treatment, is discussed. The requirements for future developments are illustrated. Expert commentary: Immunotherapy of peritoneal carcinomatosis is manageable, showing striking cancer cell killing. Improved profiles of adverse events by therapy-induced cytokine release, enhanced specific killing and optimal treatment schedules within multimodal treatment will be key factors.

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.

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.

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.

Both diabetes mellitus and hyperglycemia per se are associated with negative outcomes after cardiac surgery. In this article, we review these associations, the possible mechanisms that lead to adverse outcomes, and the epidemiology of diabetes focusing on those patients requiring cardiac surgery. We also examine outpatient and perioperative management of diabetes with the same focus. Finally, we discuss our own efforts to improve glycemic management of patients undergoing cardiac surgery at our institution, including keys to success, results of implementation, and patient safety concerns.

This study aimed to develop and assess the effectiveness of a protocol for antibiotic prophylaxis based on preoperative kidney function in patients undergoing open heart surgery. We established a protocol for antibiotic prophylaxis based on preoperative kidney function in patients undergoing open heart surgery. This novel protocol was assessed by comparing patients undergoing open heart surgery before (control group; n = 30) and after its implementation (protocol group; n = 31) at Kyoto University Hospital between July 2012 and January 2013. Surgical site infections (SSIs) were observed in 4 control group patients (13.3 %), whereas no SSIs were observed in the protocol group patients (P < 0.05). The total duration of antibiotic use decreased significantly from 80.7 ± 17.6 h (mean ± SD) in the control group to 55.5 ± 14.9 h in the protocol group (P < 0.05). Similarly, introduction of the protocol significantly decreased the total antibiotic dose used in the perioperative period (P < 0.05). Furthermore, antibiotic regimens were changed under suspicion of infection in 5 of 30 control group patients, whereas none of the protocol group patients required this additional change in the antibiotic regimen (P < 0.05). Our novel antibiotic prophylaxis protocol based on preoperative kidney function effectively prevents SSIs in patients undergoing open heart surgery.

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.

A pilot study to measure and compare blood and urine microRNAs miR-210 and miR-16 in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB) and off-pump coronary artery bypass grafting surgery. Frequent serial blood and urine samples were taken from patients undergoing cardiac surgery with CPB (n = 10) and undergoing off-pump cardiac surgery (n = 5) before, during, and after surgery. Circulating miR-210 and miR-16 levels were determined by relative quantification real-time polymerase chain reaction. Levels of plasma-free haemoglobin (fHb), troponin-T, creatine kinase, and creatinine were measured. Perioperative serum miR-210 and miR-16 were elevated significantly compared to preoperative levels in patients undergoing cardiac surgery with CPB (CPB vs. Pre Op and Rewarm vs. Pre Op; p < .05 for both). There were increases of greater than 200% in miR-210 levels during rewarming and immediately postoperatively and a 3,000% increase in miR-16 levels immediately postoperatively in urine normalized to urinary creatinine concentration. Serum levels of miR-16 were relatively constant during off-pump surgery. miR-210 levels increased significantly in off-pump patients perioperatively ( p < .05 Octopus on vs. Pre Op); however, the release was less marked when compared to cardiac surgery with CPB. A significant association was observed between both miR-16 and miR-210 and plasma fHb when CPB was used ( r = -.549, p < .0001 and r = -.463, p < .0001 respectively). Serum and urine concentrations of hypoxically regulated miR-210 and hemolysis-associated miR-16 increased in cardiac surgery using CPB compared to off-pump surgery. These molecules may have utility in indicating severity of cardiac, red cell, and renal injury during cardiac surgery.

Background: The thought of having a surgery can be stressful for everyone. Providing the necessary information to the patient can help both the patient and the treatment team. This study was conducted to compare the effectiveness of face-to-face verbal training and educational pamphlets on the readiness of patients for undergoing non-emergency surgeries. Materials and Methods: The study was a before–after randomized clinical trial. 90 patients scheduled to undergo non-emergency surgery who referred to Shahrekord Ayatollah Kashani Hospital in 2013 were distributed randomly and gradually into two experimental groups (group of face-to-face verbal training and group of educational pamphlet) and one control group. Dependent variable of the study was pre-surgery readiness. Data analysis was carried out by using SPSS statistical software. Statistical analysis were analysis of variance (ANOVA) and correlation test. Results: Results showed that the mean scores of pre-surgery readiness in both interventional groups were significantly higher than that in the control group after the intervention (P < 0.05). However, there was no significant difference between the two experimental groups (P > 0.05). Conclusions: Each of the methods of face-to-face verbal education and using the pamphlet could be equally effective in improving the readiness of the patients undergoing surgery. Therefore, in environments where the health care providers are facing with the pressure of work and lack of sufficient time for face-to-face verbal training, suitable educational pamphlets can be used to provide the necessary information to patients and prepare them for surgery.

Managing hip fracture and lower limb surgery in the emergency setting: Potential role of non-vitamin K antagonist oral anticoagulants.

PubMed

Fisher, William

2017-06-01

Trauma, immobilization, and subsequent surgery of the hip and lower limb are associated with a high risk of developing venous thrombo-embolism (VTE). Individuals undergoing hip fracture surgery (HFS) have the highest rates of VTE among orthopedic surgery and trauma patients. The risk of VTE depends on the type and location of the lower limb injury. Current international guidelines recommend routine pharmacological thromboprophylaxis based on treatment with heparins, fondaparinux, dose-adjusted vitamin K antagonists and acetylsalicylic acid for patients undergoing emergency HFS; however, not all guidelines recommend pharmacological prophylaxis for patients with lower limb injuries. Non-vitamin K antagonist oral anticoagulants (NOACs) are indicated for VTE prevention after elective hip or knee replacement surgery, but at present are not widely recommended for other orthopedic indications despite their advantages over conventional anticoagulants and promising real-world evidence. In patients undergoing HFS or lower limb surgery, decisions on whether to anticoagulate and the most appropriate anti-coagulation strategy can be guided by weighing the risk of thromboprophylaxis against the benefit in relation to each patient's medical history and age. In addition, the nature and location of the fracture, operating times and times before fracture fixation should be considered. The current review discusses the need for anticoagulation in patients undergoing emergency HFS or lower limb surgery together with the current guidelines and available evidence on the use of NOACs in this setting. Appropriate thromboprophylactic strategies and practical advice on the peri-operative management of patients who present to the Emergency Department on a NOAC before emergency surgery are further outlined.

Spinal fusion surgery: From relief to insecurity.

PubMed

Damsgaard, Janne B; Jørgensen, Lene B; Norlyk, Annelise; Birkelund, Regner

2017-02-01

During their decision-making process patients perceive surgery as a voluntary yet necessary choice. Surgery initiates hope for a life with less pain but also creates a feeling of existential insecurity in terms of fear, isolation and uncertainty. The aim of this study was to explore how patients experience their situation from the point of making the decision to undergo spinal fusion surgery to living their everyday life after surgery. A phenomenological-hermeneutic study design was applied based on the French philosopher Paul Ricoeur's theory of interpretation. Data were collected through observations and semi-structured interviews. The recommendation and decision to undergo spinal fusion surgery felt like a turning point for the patients and brought hope of regaining their normal lives, of being a more resourceful parent, partner, friend and colleague with no or less pain. Thus, deciding to undergo surgery created a brief feeling of relief. However, life with back pain had changed the patients' understanding of themselves. Consequently, some patients postoperatively experienced insecurity and a weakened self-image with difficulties creating meaning in their lives. Being recommended and undergoing spinal fusion surgery initiates hope for a life with less pain and altered life conditions. At the same time, paradoxically, this creates a feeling of existential insecurity in terms of facing the surgery and the future to come. It is, therefore, important to recognise and include the patients' everyday life experiences concerning how they give (or may not give) meaning to their illness, i.e. their understanding of how it is affecting them. These aspects are essential for the patients' definition and re-definition of themselves and thus crucial to draw upon in the relationship and communication between patient and healthcare professional.

Lubbe, D; Semple, P

To demonstrate the importance of pre-operative ear, nose and throat assessment in patients undergoing endoscopic, transsphenoidal surgery for pituitary tumours. Literature pertaining to the pre-operative otorhinolaryngological assessment and management of patients undergoing endoscopic anterior skull base surgery is sparse. We describe two cases from our series of 59 patients undergoing endoscopic pituitary surgery. The first case involved a young male patient with a large pituitary macroadenoma. His main complaint was visual impairment. He had no previous history of sinonasal pathology and did not complain of any nasal symptoms during the pre-operative neurosurgical assessment. At the time of surgery, a purulent nasal discharge was seen emanating from both middle meati. Surgery was abandoned due to the risk of post-operative meningitis, and postponed until the patient's chronic rhinosinusitis was optimally managed. The second patient was a 47-year-old woman with a large pituitary macroadenoma, who presented to the neurosurgical department with a main complaint of diplopia. She too gave no history of previous nasal problems, and she underwent uneventful surgery using the endoscopic, transnasal approach. Two weeks after surgery, she presented to the emergency unit with severe epistaxis. A previous diagnosis of hereditary haemorrhagic telangiectasia was discovered, and further surgical and medical intervention was required before the epistaxis was finally controlled. Pre-operative otorhinolaryngological assessment is essential prior to endoscopic pituitary or anterior skull base surgery. A thorough otorhinolaryngological history will determine whether any co-morbid diseases exist which could affect the surgical field. Nasal anatomy can be assessed via nasal endoscopy and sinusitis excluded.

Anesthesiologists are confronted with an increasing population of patients undergoing noncardiac surgery who are at risk for cardiac complications in the perioperative period. Perioperative cardiac complications are responsible for significant mortality and morbidity. The aim of the present study was to determine the incidence of perioperative (operative and postoperative) cardiac complications and correlations between the incidence of perioperative cardiac complications and type of surgical procedure, age, presence of concurrent deseases. A total of 100 patients with cardiac diseases undergoing noncardiac surgery were included in the prospective study (Group A 50 patients undergoing intraperitoneal surgery and Group B 50 patients undergoing breast and thyroid surgery). The patients were followed up during the perioperative period and after surgery until leaving hospital to assess the occurrence of cardiac events. Cardiac complications (systemic arterial hypertension, systemic arterial hypotension, abnormalities of cardiac conduction and cardiac rhythm, perioperative myocardial ischemia and acute myocardial infarction) occurred in 64% of the patients. One of the 100 patients (1%) had postoperative myocardial infarction which was fatal. Systemic arterial hypertension occured in 57% of patients intraoperatively and 33% postoperatively, abnormalities of cardiac rhythm in 31% of patients intraoperatively and 17% postoperatively, perioperative myocardial ischemia in 23% of patients intraoperatively and 11% of postoperatively. The most often cardiac complications were systemic arterial hypertension, abnormalities of cardiac rhythm and perioperative mvocardial ischemia. Factors independently associated with the incidence of cardiac complications included the type of surgical procedure, advanced age, duration of anaesthesia and surgery, abnormal preoperative electrocardiogram, abnormal preoperative chest radiography and diabetes.

PubMed Central

2014-01-01

Introduction The aim of this study was to identify the determinants of distance walked in six-minute walk test (6MWD) in patients undergoing cardiac surgery at hospital discharge. Methods The assessment was performed preoperatively and at discharge. Data from patient records were collected and measurement of the Functional Independence Measure (FIM) and the Nottingham Health Profile (NHP) were performed. The six-minute walk test (6MWT) was performed at discharge. Patients undergoing elective cardiac surgery, coronary artery bypass grafting or valve replacement were eligible. Patients older than 75 years who presented arrhythmia during the protocol, with psychiatric disorders, muscular or neurological disorders were excluded from the study. Results Sixty patients (44.26% male, mean age 51.53 ± 13 years) were assessed. In multivariate analysis the following variables were selected: type of surgery (P = 0.001), duration of cardiopulmonary bypass (CPB) (P = 0.001), Functional Independence Measure - FIM (0.004) and body mass index - BMI (0.007) with r = 0.91 and r2 = 0.83 with P < 0.001. The equation derived from multivariate analysis: 6MWD = Surgery (89.42) + CPB (1.60) + MIF (2.79 ) - BMI (7.53) - 127.90. Conclusion In this study, the determinants of 6MWD in patients undergoing cardiac surgery were: the type of surgery, CPB time, functional capacity and body mass index. PMID:24885130

Retrospective administrative database analysis. To investigate the effect of osteoporosis (OS) on complications and outcomes in patients undergoing cervical spine surgery. OS is the most prevalent degenerative human bone disease, and spine surgeons will inevitably perform procedures on patients with OS. These patients might present a difficult patient cohort because many fixation techniques depend on bone quality and adequate bone healing--both of which are compromised in OS. The nationwide inpatient sample was queried using the Ninth Revision, Clinical Modification procedural codes for cervical spine procedures and diagnosis codes for degenerative conditions of cervical spine from 2002 to 2011. Patients were separated into two cohorts, those patients with OS and those without OS. Demographics, hospital characteristics, and adjusted complication likelihood were analyzed. Multivariate regression analysis was performed to determine odds of revision surgery in patients with OS. Of all patients undergoing degenerative cervical spine surgery, 2% were identified as having OS (32,557 of a sample of 1,602,129 patients). Osteoporotic patients were more likely to undergo posterior cervical spine fusion when compared with those patients without OS (11.3% vs. 5.4%, P < 0.0001). Moreover, circumferential fusion was performed 3 times more frequently in the osteoporotic cohort. Adjusted complications showed increased odds for postoperative hemorrhage (odds ratio = 1.70, 95% confidence interval = 1.46-1.98, P < 0.0001). Patients with OS stayed in the hospital longer (3.5 vs. 2.5 days, P < 0.0001) and had 30% costlier hospitalizations. Multivariate for revision surgery indicated that osteoporotic patients had significantly increased odds of revision surgery (odds ratio = 1.54, P ≤ 0.0001) when referenced to non-osteoporotic patients undergoing cervical spine surgery. Osteoporotic patients were more likely to undergo revision surgery, have longer hospitalizations, and have higher hospitalization costs, than their non-osteoporotic counterparts. 3.

To determine the prevalence of impaired olfaction in individuals presenting for cardiac surgery and the independent association between impaired olfaction and postoperative delirium and cognitive decline. Nested prospective cohort study. Academic hospital. Individuals undergoing coronary artery bypass, valve surgery, or both (n = 165). Olfaction was measured using the Brief Smell Identification Test, with impaired olfaction defined as an olfactory score below the fifth percentile of normative data. Delirium was assessed using a validated chart review method. Cognitive performance was assessed using a neuropsychological testing battery at baseline and 4 to 6 weeks after surgery. Impaired olfaction was identified in 54 of 165 participants (33%) before surgery. Impaired olfaction was associated with greater adjusted risk of postoperative delirium (relative risk = 1.90, 95% confidence interval = 1.17-3.09, P = .009). There was no association between impaired olfaction and change in composite cognitive score in the overall study population. Impaired olfaction is prevalent in individuals undergoing cardiac surgery and is associated with greater adjusted risk of postoperative delirium but not cognitive decline. Impaired olfaction may identify unrecognized vulnerability to postoperative delirium in individuals undergoing cardiac surgery. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

To investigate the non-inferiority of postoperative single-dose intravenous antimicrobial prophylaxis to multiple-dose intravenous antimicrobial prophylaxis in terms of the incidence of surgical site infections (SSIs) in patients undergoing elective rectal cancer surgery by a prospective randomized study. Patients undergoing elective surgery for rectal cancer were randomized to receive a single intravenous injection of flomoxef (group 1) or five additional doses (group 2) of flomoxef after the surgery. All the patients had received preoperative oral antibiotic prophylaxis (kanamycin and erythromycin) after mechanical cleansing within 24 h prior to surgery, and had received intravenous flomoxef during surgery. A total of 279 patients (including 139 patients in group 1 and 140 in group 2) were enrolled in the study. The incidence of SSIs was 13.7% in group 1 and 13.6% in group 2 (difference [95% confidence interval]: -0.2% [-0.9 to 0.7%]). The incidence of SSIs was not significantly different in patients undergoing elective rectal surgery who were treated using a single dose of postoperative antibiotics compared to those treated using multiple-dose antibiotics when preoperative mechanical and chemical bowel preparations were employed.

Elderly patients are often judged to be fit for emergency surgery based on age alone. This study identified risk factors predictive of in-hospital mortality amongst octogenarians undergoing emergency general surgery. A retrospective review of octogenarians undergoing emergency general surgery over 3 years was performed. Parametric survival analysis using Cox multivariate regression model was used to identify risk factors predictive of in-hospital mortality. Hazard ratios (HR) and corresponding 95% confidence interval were calculated. Seventy-three patients with a median age of 84 years were identified. Twenty-eight (38%) patients died post-operatively. Multivariate analysis identified ASA grade (ASA 5 HR 23.4 95% CI 2.38-230, p = 0.007) and chronic obstructive pulmonary disease (COPD) (HR 3.35 95% CI 1.15-9.69, p = 0.026) to be the only significant predictors of in-hospital mortality. Identification of high risk surgical patients should be based on physiological fitness for surgery rather than chronological age. Crown Copyright © 2014. Published by Elsevier Ltd.

The presence of clowns in health care settings is a program used in many countries to reduce distress in children who are undergoing surgery. The aim of the present study is to determine the effect of the presence of clowns on children's distress and maladaptive behaviours while in hospital for minor surgery. The sample consisted of 61 pediatric patients (aged 3-12 years) undergoing general anesthesia for minor surgery. Participants were assigned to two groups: experimental and control group. The child's distress was assessed using FAS (Facial Affective Scale). Postoperative maladaptive behaviors were evaluated one week after surgery, using the PHBQ (Post-Hospital Behavior Questionnaire). Our results suggest that clowns are not able to reduce the child's level of distress. However, postoperative maladaptive behaviours in the experimental group decreased, but the decrease was not statistically significant. Further research is needed to determine the effects of clowns in hospitals, taking into account age, sex, parents' presence, and diverse hospital settings.

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.

Respiratory support of neonates during and following laser surgery for retinopathy of prematurity (ROP) is commonly accomplished using endotracheal intubation and mechanical ventilation. However, most patients undergoing ROP surgery have been weaned off mechanical ventilation days or weeks before the surgery. When they are electively re-intubated for ROP surgery, it can be difficult to extubate them postoperatively. One of the three level III neonatal intensive care units (NICUs) in the Intermountain Healthcare system initiated a program of using nasopharyngeal prongs, rather than endotracheal intubation, for respiratory support during ROP surgery. We performed an historic cohort analysis of all neonates undergoing ROP surgery during their NICU stay at the three level III NICU's between 1 January 2002 and 31 March 2006. Data collected included birth weight, gestational age at delivery and corrected gestational age at ROP surgery, whether or not they were intubated in the days immediately preceding the ROP surgery, whether or not they were electively intubated for the ROP surgery, the respiratory modality used during and the 3 days following ROP surgery, and all blood gas determinations and respiratory charges during this period. Fifty-four patients underwent ROP surgery during this period. All 23 from NICUs 'A' and 'B' had endotracheal intubation for surgery, while in NICU 'C' 24 were managed using nasopharyngeal prongs. The birth weights of those intubated for surgery (661+/-180 g, mean+/-s.d.) were similar to those not intubated (732+/-180 g). Similarly, the gestational age at birth did not differ between those intubated for surgery (25.2+/-1.3 week) and those not (25.6+/-2.1 week). The day following surgery, 77% (23/30) of those who had been intubated for surgery remained intubated and on mechanical ventilation, whereas only one (4%) of those not intubated for surgery was intubated in the postoperative period (P<0.001). On day 3 following surgery, 50% (15/30) of those intubated for surgery remained intubated and on mechanical ventilation, whereas none of those not intubated for surgery were intubated (P<0.001). Management with nasopharyngeal prongs did not result in higher PCO(2)s, or lower pH values, during or after surgery. Respiratory charges for the 3 days following surgery were 1762+/-678 dollars (mean+/-s.d.)/patient among those intubated versus 357+/-352 dollars/patient for those managed with nasopharyngeal prongs (P<0.001). Neonates undergoing laser surgery for ROP can often be supported intraoperatively and postoperatively using nasopharyngeal prongs, thus avoiding the need for endotracheal intubation.

The aim of this study was to determine the influence of music on anxiety levels and physiologic parameters in women undergoing gynecologic surgery. This study employed a pre- and posttest experimental design with nonrandom assignment. Ninety-seven women undergoing gynecologic surgery were included in the study, where 49 were allocated to the control group (nonmusic group) and 48 were assigned to the experimental group (music group). Preoperative anxiety was measured using the State Trait Anxiety Inventory (STAI) while noninvasive instruments were used in measuring the patients' physiologic parameters (blood pressure [BP], pulse [P], and respiration [R]) at two time periods. Women allocated in the experimental group had lower STAI scores (t = 17.41, p < .05), systolic (t = 6.45, p < .05) and diastolic (t = 2.80, p < .006) BP, and P rate (PR; t = 7.32, p < .05) than in the control group. This study provides empirical evidence to support the use of music during the preoperative period in reducing anxiety and unpleasant symptoms in women undergoing gynecologic surgery. © The Author(s) 2014.

To examine whether there are changes in the distance between the orotracheal tubeand carina induced by orthostatic retractor placement or by pneumoperitoneum insufflation in obese patients undergoing gastroplasty. 60 patients undergoing bariatric surgery by two techniques: open (G1) or videola-paroscopic (G2) gastroplasty were studied. After tracheal intubation, adequate ventilation of both hemitoraxes was confirmed by lung auscultation. The distance orotracheal tube-carina was estimated with the use of a fiber bronchoscope before and after installation of orthostatic retractors in G1 or before and after insufflation of pneumoperitoneum in patients in G2. G1 was composed of 22 and G2 of 38 patients. No cases of endobronchial intubationwere detected in either group. The mean orotracheal tube-carina distance variation was estimated in -0.03 cm (95% CI 0.06 to -0.13) in the group of patients undergoing open gastroplastyand in -0.42 cm (95% CI -0.56 to -1.4) in the group of patients undergoing videolaparoscopic gastroplasty. The extremes of variation in each group were: 0.5 cm to -1.6 cm in patients under-going open surgery and 0.1 cm to -2.2 cm in patients undergoing videolaparoscopic surgery. There was no significant change in orotracheal tube-CA distance after placementof orthostatic retractors in patients undergoing open gastroplasty. There was a reduction inorotracheal tube-CA distance after insufflation of pneumoperitoneum in patients undergoing videolaparoscopic gastroplasty. We recommend attention to lung auscultation and to signals of ventilation monitoring and reevaluation of orotracheal tube placement after peritoneal insufflation.

Complete cytoreduction is the most important prognostic factor in ovarian cancer. However, there exist conflicting data on whether the removal of microscopic tumor metastasis in macroscopically unsuspicious retroperitoneal lymph nodes is beneficial. Ovarian cancer tissues and tissues from lymph node metastasis of 30 patients with FIGO IIIC or IV disease undergoing neoadjuvant chemotherapy (NACT) were obtained and assessed using a validated regression score. Histopathological markers, size of largest tumor focus, and overall score were evaluated in lymph node and ovarian tissue. Regression and known prognostic factors were analyzed for influence on survival. No difference in the overall score between lymph nodes and ovarian tissue was shown, however, single parameters such as fibrosis and pattern of tumor infiltration, were significantly different. The pattern of tumor regression in lymph nodes and ovarian tissue are of prognostic value. Lymph node dissection even of unsuspicious nodes should, therefore, be performed.

To determine if dogs that undergo laparotomy for cholecystectomy suffer from a greater number or magnitude of perianesthetic complications, including hypotension, hypothermia, longer recovery time, and lower survival rate, than dogs that undergo laparotomy for hepatic surgery without cholecystectomy. Retrospective cohort study. One hundred and three dogs, anesthetised between January 2007 and October 2011. The variables collected from the medical record included age, weight, gender, surgical procedure, pre-operative bloodwork, American Society of Anesthesiologists (ASA) status, emergency status, total bilirubin concentration, anesthetic agents administered, body temperature nadir, final body temperature, hypotension, duration of hypotension, blood pressure nadir, intraoperative drugs, anesthesia duration, surgery duration, time to extubation, final diagnosis, days spent in the intensive care unit (ICU), total bill, survival to discharge, and survival to follow-up. No significant difference in body temperature nadir, final temperature, presence of hypotension, duration of hypotension, blood pressure nadir, the use of inotropes, or final outcome was found between dogs undergoing cholecystectomy and dogs undergoing exploratory laparotomy for other hepatic disease. Dogs that had cholecystectomy had longer anesthesia durations and longer surgery durations than dogs that did not have cholecystectomy. No significant differences existed for temperature nadir (34.8 versus 35.3°C; non-cholecystectomy versus cholecystectomy), final temperature (35.6 versus 35.9°C), time to extubation (30 versus 49 minutes), duration of hypotension (27 versus 21 minutes), or MAP nadir (56 versus 55 mmHg). Hypotension occurred in 66% and 74% and inotropes were used in 64% and 53%, for non-cholecystectomy and cholecystectomy patients, respectively. Dogs that underwent cholecystectomies did not suffer a greater number of anesthesia complications than did dogs undergoing hepatic surgery without cholecystectomies. © 2013 Association of Veterinary Anaesthetists and the American College of Veterinary Anesthesia and Analgesia.

Assessing the neurodevelopmental status of infants with congenital heart disease before surgery provides a means of identifying those at heightened risk of developmental delay. This study aimed to investigate factors impacting clinical feasibility of pre-operative neurodevelopmental assessment of infants undergoing early open heart surgery. Infants who underwent open heart surgery prior to 4 months of age participated in this cross-sectional study. The Test of Infant Motor Performance and Prechtl's Assessment of General Movements were undertaken on infants pre-operatively. When assessments could not be undertaken, reasons were ascribed to either infant or environmental circumstances. Demographic data and Aristotle scores were compared between groups of infants who did or did not undergo assessment. Binary logistic regression was used to explore associations. A total of 60 infants participated in the study. Median gestational age was 38.78 weeks (interquartile range: 36.93-39.72). Of these infants, 37 (62%) were unable to undergo pre-operative assessment. Twenty-four (40%) could not complete assessment due to infant-related factors and 13 (22%) due to environmental-related factors. For every point increase in the Aristotle Patient-Adjusted Complexity score, the infants likelihood of being unable to undergo assessment increased by 35% (odds ratio: 0.35; 95% confidence interval: 1.03-1.77, P = 0.03). Over half of the infants undergoing open heart surgery were unable to complete pre-operative neurodevelopmental assessment. The primary reason for this was infant-related medical instability. Findings suggest further research is warranted to investigate whether the Aristotle Patient-Adjusted Complexity score might serve as an indicator to inform developmental surveillance with this medically fragile cohort. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

To predict who will undergo midurethral sling surgery (surgery) after initial pelvic floor muscle training (physiotherapy) for stress urinary incontinence in women. This was a cohort study including women with moderate to severe stress incontinence who were allocated to the physiotherapy arm from a previously reported multicentre trial comparing initial surgery or initial physiotherapy in treating stress urinary incontinence. Crossover to surgery was allowed. Data from 198/230 women who were randomized to physiotherapy was available for analysis, of whom 97/198 (49 %) crossed over to surgery. Prognostic factors for undergoing surgery after physiotherapy were age <55 years at baseline (OR 2.87; 95 % CI 1.30-6.32), higher educational level (OR 3.28; 95 % CI 0.80-13.47), severe incontinence at baseline according to the Sandvik index (OR 1.77; 95 % CI 0.95-3.29) and Urogenital Distress Inventory; incontinence domain score (OR 1.03; per point; 95 % CI 1.01-1.65). Furthermore, there was interaction between age <55 years and higher educational level (OR 0.09; 95 % CI 0.02-0.46). Using these variables we constructed a prediction rule to estimate the risk of surgery after initial physiotherapy. In women with moderate to severe stress incontinence, individual prediction for surgery after initial physiotherapy is possible, thus enabling shared decision making for the choice between initial conservative or invasive management of stress urinary incontinence.

Patients with Addison's disease undergoing cardiac surgery are at risk of developing a crisis. There is no consensus on the preoperative and intraoperative management of this group of patients undergoing cardiac surgery so the recommendations for non-cardiac patients are often used. The consensus statement from the international task force of the American College of Critical Care medicine recommends 100 mg of intravenous hydrocortisone for patients with adrenal insufficiency in septic shock, but in patients undergoing surgery, especially with extracorporeal circulation, the dosage may even be higher. We report our management of a patient with well-controlled adrenal insufficiency for 30 years who developed intraoperative Addisonian crisis despite the recommended preoperative corticosteroid supplementation. The importance of adequate corticosteroid supplementation for cardiac surgery patients, adapting the surgical strategy to allow for optimal management of potential complications and close monitoring with heightened awareness are discussed.

Significant mitral regurgitation in patients undergoing transcatheter aortic valve replacement (TAVR) is associated with increased mortality. The aim of this study is to determine if surgical correction of both aortic and mitral valves in high risk patients with concomitant valvular disease would offer patients better outcomes than TAVR alone. A retrospective analysis of 43 high-risk patients who underwent concomitant surgical aortic valve replacement and mitral valve surgery from 2008 to 2012 was performed. Immediate and long term survival were assessed. There were 43 high-risk patients with severe aortic stenosis undergoing concomitant surgical aortic valve replacement and mitral valve surgery. The average age was 80 ± 6 years old. Nineteen (44%) patients had prior cardiac surgery, 15 (34.9%) patients had chronic obstructive lung disease, and 39 (91%) patients were in congestive heart failure. The mean Society of Thoracic Surgeons Predicted Risk of Mortality for isolated surgical aortic valve replacement for the cohort was 10.1% ± 6.4%. Five patients (11.6%) died during the index admission and/or within thirty days of surgery. Mortality rate was 25% at six months, 35% at 1 year and 45% at 2 years. There was no correlation between individual preoperative risk factors and mortality. High-risk patients with severe aortic stenosis and mitral valve disease undergoing concomitant surgical aortic valve replacement and mitral valve surgery may have similar long term survival as that described for such patients undergoing TAVR. Surgical correction of double valvular disease in this patient population may not confer mortality benefit compared to TAVR alone.

Parenchymal transection represents a crucial step during liver surgery and many different techniques have been described so far. Stapler resection is supposed to be faster than CUSA resection. However, whether speed impacts on the inflammatory response in patients undergoing liver resection (LR) remains unclear. This is a randomized controlled trial including 40 patients undergoing anatomical LR. Primary endpoint was transection speed (cm2/min). Secondary endpoints included the perioperative change of pro- and anti-inflammatory cytokines, overall surgery duration, length of hospital stay, morbidity and mortality. Mean transection speed was significantly higher in patients undergoing stapler hepatectomy compared to CUSA resection (CUSA: 1 (0.4) cm2/min vs. Stapler: 10.8 (6.1) cm2/min; p<0.0001). Analyzing the impact of surgery duration on inflammatory response revealed a significant correlation between IL-6 levels measured at the end of surgery and the overall length of surgery (p<0.0001, r = 0.6188). Patients undergoing CUSA LR had significantly higher increase of interleukin-6 (IL-6) after parenchymal transection compared to patients with stapler hepatectomy in the portal and hepatic veins, respectively (p = 0.028; p = 0.044). C-reactive protein levels on the first post-operative day were significantly lower in the stapler cohort (p = 0.010). There was a trend towards a reduced overall surgery time in patients with stapler LR, especially in the subgroup of patients undergoing minor hepatectomies (p = 0.020). Liver resection using staplers is fast, safe and suggests a diminished inflammatory response probably due to a decreased parenchymal transection time. ClinicalTrials.gov NCT01785212.

Background Parenchymal transection represents a crucial step during liver surgery and many different techniques have been described so far. Stapler resection is supposed to be faster than CUSA resection. However, whether speed impacts on the inflammatory response in patients undergoing liver resection (LR) remains unclear. Materials and Methods This is a randomized controlled trial including 40 patients undergoing anatomical LR. Primary endpoint was transection speed (cm2/min). Secondary endpoints included the perioperative change of pro- and anti-inflammatory cytokines, overall surgery duration, length of hospital stay, morbidity and mortality. Results Mean transection speed was significantly higher in patients undergoing stapler hepatectomy compared to CUSA resection (CUSA: 1 (0.4) cm2/min vs. Stapler: 10.8 (6.1) cm2/min; p<0.0001). Analyzing the impact of surgery duration on inflammatory response revealed a significant correlation between IL-6 levels measured at the end of surgery and the overall length of surgery (p<0.0001, r = 0.6188). Patients undergoing CUSA LR had significantly higher increase of interleukin-6 (IL-6) after parenchymal transection compared to patients with stapler hepatectomy in the portal and hepatic veins, respectively (p = 0.028; p = 0.044). C-reactive protein levels on the first post-operative day were significantly lower in the stapler cohort (p = 0.010). There was a trend towards a reduced overall surgery time in patients with stapler LR, especially in the subgroup of patients undergoing minor hepatectomies (p = 0.020). Conclusions Liver resection using staplers is fast, safe and suggests a diminished inflammatory response probably due to a decreased parenchymal transection time.

The effect of mannitol on intraoperative brain relaxation in patients undergoing supratentorial tumor surgery: study protocol for a randomized controlled trial

PubMed Central

2014-01-01

Background The risk of brain swelling after dural opening is high in patients with midline shift undergoing supratentorial tumor surgery. Brain swelling may result in increased intracranial pressure, impeded tumor exposure, and adverse outcomes. Mannitol is recommended as a first-line dehydration treatment to reduce brain edema and enable brain relaxation during neurosurgery. Research has indicated that mannitol enhanced brain relaxation in patients undergoing supratentorial tumor surgery; however, these results need further confirmation, and the optimal mannitol dose has not yet been established. We propose to examine whether different doses of 20% mannitol improve brain relaxation in a dose-dependent manner when administered at the time of incision. We will examine patients with preexisting mass effects and midline shift undergoing elective supratentorial brain tumor surgery. Methods This is a single-center, randomized controlled, parallel group trial that will be carried out at Beijing Tiantan Hospital, Capital Medical University. Randomization will be achieved using a computer-generated table. The study will include 220 patients undergoing supratentorial tumor surgery whose preoperative computed tomography/magnetic resonance imaging results indicate a brain midline shift. Patients in group A, group B, and group C will receive dehydration treatment at incision with 20% mannitol solutions of 0.7, 1.0, and 1.4 g/kg, respectively, at a rate of 600 mL/h. The patients in the control group will not receive mannitol. The primary outcome is an improvement in intraoperative brain relaxation and dura tension after dehydration with mannitol. Secondary outcomes are postoperative outcomes and the incidence of mannitol side effects. Discussion The aim of this study is to determine the optimal dose of 20% mannitol for intraoperative infusion. We will examine brain relaxation and outcome in patients undergoing supratentorial tumor surgery. If our results are positive, the study will indicate the optimal dose of mannitol to improve brain relaxation and avoid side effects during brain tumor surgery.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors located in the alimentary tract. Its usual manifestation is gastrointestinal bleeding. However, small asymptomatic lesions are frequently detected as incidental finding. Characteristically, most GISTs (> 95%) are positive for the KIT protein (CD117) by IHC staining and approximately 80%-90% of GISTs carry a mutation in the c-KIT or PDGFRA genes. Mutational analysis should be performed when planning adjuvant and neoadjuvant therapy, due to its possible resistance to conventional treatment. The arise of tyrosine kinase inhibitor has supposed a revolution in GISTs treatment being useful as adjuvant, neoadjuvant or recurrence disease treatment. That is why a multidisciplinary approach to this disease is required. The correct characterization of the tumor at diagnosis (the diagnosis of recurrences and the evaluation of the response to treatment with tyrosine kinase inhibitors) is fundamental for facing these tumors and requires specialized Endoscopist, Radiologists and Nuclear Medicine Physician. Surgery is the only potentially curative treatment for suspected resectable GIST. In the case of high risk GISTs, surgery plus adjuvant Imatinib-Mesylate for 3 years is the standard treatment. Neoadjuvant imatinib-mesylate should be considered to shrink the tumor in case of locally advanced primary or recurrence disease, unresectable or potentially resectable metastasic tumors, and potentially resectable disease in complex anatomic locations to decrease the related morbidity. In the case of Metastatic GIST under Neoadjuvant treatment, when there are complete response, stable disease or limited disease progression, complete cytoreductive surgery could be a therapeutic option if feasible.

To gather standardized information of current perioperative management of gynecological oncology patients and to evaluate up to what extent the Enhanced Recovery after Surgery (ERAS) elements are established in the clinical routine of gynecologic oncology units in Germany. We performed a multi-centric nationwide survey among 654 primary, secondary and maximal health care gynecological departments in Germany. A multiple-choice questionnaire based on the principles of ERAS was developed to gather information about perioperative management of two fictional cases in gynecological oncology. One hundred four units (22%) have been taken the survey. Only 49.5% of surveyed hospitals claimed to be adherent to more than 70% of ERAS elements in managing perioperative period of primary cytoreductive surgery in ovarian cancer patients. 21% of these hospitals implemented more than 80% and only 8.4% implemented more than 90%. The results in border-line tumors operations did not differ from those of ovarian cancer operations. The implementation of ERAS elements in gynecologic oncology in Germany is still not satisfying as only half of the departments will now be able to apply 70% of these principles. Therefore, we plan the second step of this survey in order to be able to build a consistent structured reporting platform between gynecological oncology units in Germany to facilitate the wide implementation and standardization of ERAS protocol.

Occlusive complication is a common event in the colo-rectal cancer (20-30% of cases). Operative mortality and 5 yrs survival of not occlusive cancer vs occlusive cancer is 11% vs 23% and 45% vs 25% rispectively. In occlusive cancer the level of parietal infiltration affects considerably the local and peritoneal recurrence. 50% of all patients underwent a surgical re-operation for colo-rectal cancer have peritoneal neoplastic implant. The resolution of occlusive complication in immediate or delayed urgency with decompressive derivation, it allows to perform an integrated treatment of choice that it could guarantee the oncological radical procedure. RATIONALE-METHODS: The intraperitoneal hyperthermic chemotherapy (IPHC) combined with radical or cytoriductive surgery performs its action through sinergistic effects of high dosage and concentration of drugs and hyperthermia. These agents perform a cell killing with a direct contact against micro and/or macroscopic neoplastic residue. In radical surgery with curative intent, the association with IPHC ("preventive" adjuvant) has got as objective the distruction of microscopic local or peritoneal metastasis. In occlusive cancer with synchronous or metachronous peritoneal carcinomatosis, the performance of the cytoreductive surgery with IPHC ("therapeutic" adjuvant) is the only treatment that improves the survival and the quality of remainig life. The clinical results reported by many Istitutions indicates that the 2-5 yrs survivals are 45-60% and 20-30% rispectively. These data lead us to believe that an optimal eradication of micro and/or macroscopic peritoneal spreading could be optained also in occlusive colo-rectal cancer.

Clinical management of renal cell carcinoma with venous tumor thrombus.

Agochukwu, Nnenaya; Shuch, Brian

2014-06-01

Venous invasion is common in advanced renal cell carcinoma (RCC) due to the unique biology of this cancer. The presence of a tumor thrombus often makes clinical management challenging. In this review, we detail specific preoperative, perioperative, and surgical strategies involving the care of the complex kidney cancer patient with venous tumor involvement. We performed a comprehensive review of selected peer-reviewed publications regarding RCC tumor thrombus biology, medical and surgical management techniques, and immediate and long-term outcomes. The perioperative management may require special imaging techniques, preoperative testing, very recent imaging, and consultation with other surgical services. There are various approaches to these patients as the clinical presentation, stage of disease, primary tumor size, level of thrombus, degree of venous occlusion, presence of bland thrombus, and primary tumor laterality influence management. Select patients with metastatic disease can do well with cytoreductive nephrectomy and thrombectomy. Those with localized disease have a high risk of recurrence; however, some patients can exhibit durable survival with surgery alone. The evolving surgical and medical treatments are discussed. Even when these surgeries are performed in high volume centers, significant perioperative complications are common and greater complications are seen with higher thrombus extent. If surgery is attempted, it is important for urologic oncologists to follow strict attention to specific surgical principles. These general principles include complete vascular control, avoidance of thrombus embolization, close hemodynamic monitoring, and institutional resources for caval resection/replacement and venous bypass if necessary.

Update on the prevention of local recurrence and peritoneal metastases in patients with colorectal cancer.

PubMed

Sugarbaker, Paul H

2014-07-28

The prevention of a disease process has always been superior to the treatment of the same disease throughout the history of medicine and surgery. Local recurrence and peritoneal metastases occur in approximately 8% of colon cancer patients and 25% of rectal cancer patients and should be prevented. Strategies to prevent colon or rectal cancer local recurrence and peritoneal metastases include cytoreductive surgery and hyperthermic perioperative chemotherapy (HIPEC). These strategies can be used at the time of primary colon or rectal cancer resection if the HIPEC is available. At institutions where HIPEC is not available with the treatment of primary malignancy, a proactive second-look surgery is recommended. Several phase II studies strongly support the proactive approach. If peritoneal metastases were treated along with the primary colon resection, 5-year survival was seen and these results were superior to the results of treatment after peritoneal metastases had developed as recurrence. Also, prophylactic HIPEC improved survival with T3/T4 mucinous or signet ring colon cancers. A second-look has been shown to be effective in two published manuscripts. Unpublished data from MedStar Washington Cancer Institute also produced favorable date. Rectal cancer with peritoneal metastases may not be so effectively treated. There are both credits and debits of this proactive approach. Selection factors should be reviewed by the multidisciplinary team for individualized management of patients with or at high risk for peritoneal metastases.

To better define the prevalence and location of full-thickness articular cartilage lesions in elite football players undergoing knee magnetic resonance imaging (MRI) at the National Football League (NFL) Invitational Combine and assess the association of these lesions with previous knee surgery. We performed a retrospective review of all participants in the NFL Combine undergoing a knee MRI scan from 2005 to 2009. Each MRI scan was reviewed for evidence of articular cartilage disease. History of previous knee surgery including anterior cruciate ligament reconstruction, meniscal procedures, and articular cartilage surgery was recorded for each athlete. Knees with a history of previous articular cartilage restoration surgery were excluded from the analysis. A total of 704 knee MRI scans were included in the analysis. Full-thickness articular cartilage lesions were associated with a history of any previous knee surgery (P < .001) and, specifically, previous meniscectomy (P < .001) but not with anterior cruciate ligament reconstruction (P = .7). Full-thickness lesions were present in 27% of knees with a previous meniscectomy compared with 12% of knees without any previous meniscal surgery. Full-thickness lesions in the lateral compartment were associated with previous lateral meniscectomy (P < .001); a similar relation was seen for medial meniscus tears in the medial compartment (P = .01). Full-thickness articular cartilage lesions of the knee were present in 17.3% of elite American football players at the NFL Combine undergoing MRI. The lateral compartment appears to be at greater risk for full-thickness cartilage loss. Previous knee surgery, particularly meniscectomy, is associated with these lesions.

This study aims to conduct a meta-analysis to identify and compare the effectiveness of compressive cryotherapy and cryotherapy alone for patients undergoing knee surgery. Postoperative management is an important guarantee for the success of surgery. Cryotherapy and compression are two common nursing techniques after knee surgery, and are considered to be effective for postoperative clinical symptoms such as local pain and swelling. However, no previous meta-analyses have compared the effectiveness of compressive cryotherapy and cryotherapy alone in patients undergoing knee surgery. A meta-analysis of randomized controlled trials (RCTs). We conducted a search in MEDLINE (via Pubmed, 1990-2014), EMBASE (via Elsevier, 1990-2014), Cochrane Central Register of Controlled Trials (The Cochrane Library, 1990-2014), CINAHL (1990-2014) and China National Knowledge Infrastructure (1990-2014) databases for RCTs published in English and Chinese. The primary outcome measure of interest was visual analog scale and girth measure. Finally, a meta-analysis was carried out using RevMan 5.3. Among the 593 RCTs, 10 RCTs were selected and included into this study. These studies included 522 patients who underwent knee surgery. Patients who underwent compressive cryotherapy tended to have less pain than patients who underwent cryotherapy alone at POD2 and POD3, while compressive cryotherapy had a strong tendency towards less swelling over cryotherapy alone at POD1 and POD2. However, there was no significant difference between compressive cryotherapy and cryotherapy alone at the intermediate stage of rehabilitation after knee surgery. All adverse reactions were recorded in all included RCTs. Current evidence suggests that compressive cryotherapy is beneficial to patients undergoing knee surgery at the early rehabilitation stage. At the last stage, the effectiveness of compressive cryotherapy and cryotherapy alone were found to be similar.

Prospective cross-sectional survey. To determine the perspectives of parents of patients undergoing posterior instrumented fusion for adolescent idiopathic scoliosis (AIS) regarding simultaneous surgery and trainee participation. Simultaneous ("at the same time") surgery is under scrutiny by the public, government, payers and the medical community. The objective of this study is to determine the perspectives of parents of patients undergoing posterior instrumented fusion for adolescent idiopathic scoliosis. Our goal is to inform the national conversation on this subject with real patient and family voices. A survey was prospectively administered to 31 consecutive parents of patients undergoing posterior instrumented fusion for adolescent idiopathic scoliosis at a large academic medical center. "Overlapping" was defined as simultaneity during "noncritical" parts of an operation. "Concurrent" was defined as simultaneity that includes "critical" part(s) of an operation. Participants were asked to provide levels of agreement with overlapping and concurrent surgery and anesthesia, as well as with trainee involvement. On average, respondents "strongly agree" with the need to be informed about overlapping or concurrent surgery. They "disagree" with both overlapping and concurrent scheduling, and "disagree" with trainees operating without direct supervision, even for "non-critical" parts. Informing parents about the presence of a back-up surgeon or research demonstrating safety of simultaneous surgery did not make them agreeable to simultaneous scheduling. Parents have a strong desire to be informed of simultaneous spinal surgery as part of consent on behalf of their children. Their disagreement with simultaneous surgery, as well as with trainees operating without direct supervision, suggests discordance with current guidelines and practice and should inform the national conversation moving forward.

Reduction of cognitive function is a possible side effect after the use of cardiopulmonary bypass (CPB) during cardiac surgery. Since it has been proven that piracetam is cerebroprotective in patients undergoing coronary bypass surgery, we investigated the effects of piracetam on the cognitive performance of patients undergoing open heart surgery. Patients scheduled for elective open heart surgery were randomized to the piracetam or placebo group in a double-blind study. Patients received 12 g of piracetam or placebo at the beginning of the operation. Six neuropsychological subtests from the Syndrom Kurz Test and the Alzheimer's Disease Assessment Scale were performed preoperatively and on day 3, postoperatively. To assess the overall cognitive function and the degree of cognitive decline across all tests after the surgery, we combined the six test-scores by principal component analysis. A total of 88 patients with a mean age of 67 years were enrolled into the study. The mean duration of CPB was 110 minutes. Preoperative clinical parameters and overall cognitive functions were not significantly different between the groups. The postoperative combined score of the neuropsychological tests showed deterioration of cognitive function in both groups (piracetam: preoperative 0.19 ± 0.97 vs. postoperative -0.97 ± 1.38, p <0.0005 and placebo: preoperative -0.14 ± 0.98 vs. postoperative -1.35 ± 1.23, p <0.0005). Patients taking piracetam did not perform better than those taking placebo, and both groups had the same decline of overall cognitive function (p = 0.955). Piracetam had no cerebroprotective effect in patients undergoing open heart surgery. Unlike the patients who underwent coronary surgery, piracetam did not reduce the early postoperative decline of neuropsychological abilities in heart valve patients.

Previous studies reported conflicting evidence on the effects of obesity on outcomes after gastrointestinal surgery. The aims of this study were to explore the relationship of obesity with major post-operative complications in an international cohort and to present a meta-analysis of all available prospective data. This prospective, multi-centre study included adults undergoing both elective and emergency gastrointestinal resection, reversal of stoma, or formation of stoma. The primary endpoint was 30-day major complications (Clavien-Dindo grades III-V). A systematic search was undertaken for studies assessing the relationship between obesity and major complications after gastrointestinal surgery. Individual patient meta-analysis (IPMA) was used to analyse pooled results. This study included 2519 patients across 127 centres, of whom 560 (22.2%) were obese. Unadjusted major complication rates were lower in obese versus normal weight patients (13.0% versus 16.2%, respectively), but this did not reach statistical significance (p=0.863) on multivariate analysis for patients having surgery for either malignant or benign conditions. IPMA demonstrated that obese patients undergoing surgery for malignancy were at increased risk of major complications (odds ratio 2.10, 95% confidence interval 1.49-2.96, p<0.001), whereas obese patients undergoing surgery for benign indications were at decreased risk (OR 0.59, 95% CI 0.46-0.75, p<0.001), compared to normal weight patients. In our international data, obesity was not found to be associated with major complications following gastrointestinal surgery. Meta-analysis of available prospective data made a novel finding of obesity being associated with different outcomes depending on whether patients were undergoing surgery for benign or malignant disease.

Infusions of carbohydrates before surgery have been shown to reduce postoperative insulin resistance. Presently, we investigated the effects of a carbohydrate drink, given shortly before surgery, on postoperative insulin sensitivity. Insulin sensitivity and glucose turnover ([6, 6,(2)H(2)]-D-glucose) were measured using hyper-insulinemic, normoglycemic clamps before and after elective surgery. Sixteen patients undergoing total hip replacement were randomly assigned to preoperative oral carbohydrate administration (CHO-H, n = 8) or the same amount of a placebo drink (placebo, n = 8) before surgery. Insulin sensitivity was measured before and immediately after surgery. Patients undergoing elective colorectal surgery were studied before surgery and 24 h postoperatively (CHO-C (n = 7), and fasted (n = 7), groups). The fasted group underwent surgery after an overnight fast. In both studies, the CHO groups received 800 ml of an isoosmolar carbohydrate rich beverage the evening before the operation (100g carbohydrates), as well as another 400 ml (50g carbohydrates) 2 h before the initiation of anesthesia. Immediately after surgery, insulin sensitivity was reduced 37% in the placebo group (P < 0.05 vs. preoperatively) while no significant change was found in the CHO-H group (-16%, p = NS). During clamps performed 24h postoperatively, insulin sensitivity and whole-body glucose disposal was reduced in both groups, but the reduction was greater compared to that in the CHO-C group (-49 +/- 6% vs. -26 +/- 8%, P> 0.05 fasted vs. CHO-C). Patients given a carbohydrate drink shortly before elective surgery displayed less reduced insulin sensitivity after surgery as compared to patients undergoing surgery after an overnight fast.

Bariatric surgery is a well-documented treatment for obesity, but there are uncertainties about the degree to which such surgery is associated with health care cost reductions that are sustained over time. To provide a comprehensive, multiyear analysis of health care costs by type of procedure within a large cohort of privately insured persons who underwent bariatric surgery compared with a matched nonsurgical cohort. Longitudinal analysis of 2002-2008 claims data comparing a bariatric surgery cohort with a matched nonsurgical cohort. Seven BlueCross BlueShield health insurance plans with a total enrollment of more than 18 million persons. A total of 29 820 plan members who underwent bariatric surgery between January 1, 2002, and December 31, 2008, and a 1:1 matched comparison group of persons not undergoing surgery but with diagnoses closely associated with obesity. Standardized costs (overall and by type of care) and adjusted ratios of the surgical group's costs relative to those of the comparison group. Total costs were greater in the bariatric surgery group during the second and third years following surgery but were similar in the later years. However, the bariatric group's prescription and office visit costs were lower and their inpatient costs were higher. Those undergoing laparoscopic surgery had lower costs in the first few years after surgery, but these differences did not persist. Bariatric surgery does not reduce overall health care costs in the long term. Also, there is no evidence that any one type of surgery is more likely to reduce long-term health care costs. To assess the value of bariatric surgery, future studies should focus on the potential benefit of improved health and well-being of persons undergoing the procedure rather than on cost savings.

Despite several experimental studies on the role of S100B and NSE in fractures, no studies on the influence of surgery on the biomarker serum levels have been performed yet. The serum levels of S100B and NSE were analysed in patients with fractures that were located in the spine (group 1, n = 35) or in the lower extremity (group 2, n = 32) pre- and post-operatively. The mean S100B serum level showed a significant increase (p = 0.04) post-surgery in the patients of group 1. In patients undergoing acute surgery (< 24 hours) the mean S100B serum level was 0.23 ± 0.22 μg L(-1) pre-operatively and 1.24 ± 1.38 μg L(-1) post-operatively. Likewise, the mean S100B serum level significantly increased in group 2 after surgery (p < 0.0001). In this group patients undergoing acute surgery showed a mean S100B serum level of 0.23 ± 0.14 μg L(-1) and 1.11 ± 0.73 μg L(-1) pre- and post-operatively. This study demonstrates significant alterations of the biomarker S100B serum levels in patients undergoing surgery. Higher S100B serum levels were found within 24 hours and might be related to the acute fracture. The NSE serum levels were unchanged and this biomarker may offer the probability to serve as a future outcome predictor in studies with patients with traumatic brain injury and additional extracerebral injuries.

To describe people's experiences of suffering a lower limb fracture and undergoing surgery, from the time of injury through to the care given at the hospital and recovery following discharge. There is a lack of research on people's experiences of suffering a lower limb fracture and undergoing surgery - from injury to recovery. A qualitative approach was used. Interviews with nine participants were subjected to thematic content analysis. One theme was expressed: from realising the seriousness of the injury to regaining autonomy. Participants described feelings of frustration and helplessness when realising the seriousness of their injury. The wait prior to surgery was a strain and painful experience, and participants needed orientation for the future. They expressed feelings of vulnerability about being in the hands of staff during surgery. After surgery, in the postanaesthesia unit, participants expressed a need to have control and to feel safe in their new situation. To mobilise and regain their autonomy was a struggle, and participants stated that their recovery was extended. Participants found themselves in a new and unexpected situation and experienced pain, vulnerability and a striving for control during the process, that is, 'from realising the seriousness of the injury to regaining autonomy'. How this is managed depends on how the patient's needs are met by nurses. The nursing care received while suffering a lower limb fracture and undergoing surgery should be situation specific as well as individual specific. The safe performance of technical interventions and the nurse's comprehensive explanations of medical terms may help the patient to feel secure during the process. © 2013 John Wiley & Sons Ltd.

Primary Fallopian Tube Carcinoma: A Case Report and Literature Review

PubMed Central

Rexhepi, Meral; Trajkovska, Elizabeta; Ismaili, Hysni; Besimi, Florin; Rufati, Nagip

2017-01-01

BACKGROUND: Primary fallopian tube carcinoma (PFTC) is a rare tumour of the female genital tract with an incidence of 0.1-1.8% of all genital malignancies, and it is very difficult to diagnose preoperatively, because of its non-specific symptomatology. In most cases, it is an intraoperative finding or a histopathological diagnosis. It is a tumour that histologically and clinically resembles epithelial ovarian cancer. CASE PRESENTATION: We are reporting a case of a 62-year-old, postmenopausal women with primary fallopian tube carcinoma of the right fallopian tube in stage IA. The patient has lower abdominal pain, watery vaginal discharge and repeated episodes of bleeding from the vagina. The clinical and radiological findings suggested a right adnexal tumour with elevated CA-125 levels. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy and peritoneal washing were performed. Pathologic confirmation of primary serous cystadenocarcinoma of the right fallopian tube was made. Peritoneal washings were negative for malignancy. FIGO stage was considered as IA, and the patient received no courses of chemotherapy and postoperative radiation because she refused it. Ten months after initial surgery, the patient is alive and in good condition. CONCLUSION: Cytoreduction surgery followed by adequate cycles of chemotherapy is an important strategy to improve patients’ prognosis. PMID:28698755

The hepatic bridge.

The hepatic bridge forms a tunnel of liver parenchyma that may obscure peritoneal metastases associated with the round ligament. Visualization and then resection of nodules associated with this structure is necessary. The incidence of a hepatic bridge and the extent that it covered the round ligament was determined in consecutive patients. Extent of coverage of the round ligament by the hepatic bridge was determined: Class 1 indicates up to one-third of the round ligament obscured, Class 2 up to two-thirds and Class 3 more than two-thirds. In 102 patients in whom the round ligament of the liver could be completely visualized, 50 had a hepatic bridge. Class 1 was 22 (44%) of the bridges, Class 2 was 16 (32%) and Class 3 was 12 (24%). A hepatic bridge was more frequently present in 28 of 45 male patients (62%) vs. 22 of 57 female patients (38%). Approximately one-half of our patients having cytoreductive surgery for peritoneal metastases were observed to have a hepatic bridge. Up to 56% of these patients have Class 2 or 3 hepatic bridge and may require division of the hepatic bridge to completely visualize the contents of the tunnel created by this structure.

Jones, K R; Burney, R E; Christy, B

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.

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 purpose of this study was to determine the effect of music listening on postoperative anxiety and intubation time in patients undergoing cardiovascular surgery. Coronary artery disease and valvular heart disease affect approximately 15 million Americans and 5 million persons in the U.K. annually, with the majority of these patients being older adults. The anxiety experienced before, during and after surgery increases cardiovascular workload, thereby prolonging recovery time. Music listening as a nursing intervention has shown an ability to reduce anxiety. The study used a randomized control trial design. Sixty adults older than 65 years were randomly assigned to the control and the experimental groups. The experimental group listened to music during and after surgery, while the control group received standard postoperative care. The Spielberger State Trait Anxiety Inventory was administered to both groups before surgery and 3 days postoperatively. The mean of the differences between scores was compared using analysis of variance. Differences in mean intubation time were measured in both groups. Older adults who listened to music had lower scores on the state anxiety test (F = 5.57, p = .022) and had significantly fewer minutes of postoperative intubation (F = 5.45, p = .031) after cardiovascular surgery. Older adults undergoing cardiovascular surgery who listen to music had less anxiety and reduced intubation time than those who did not.

Women with breast cancer who carry BRCA1 or BRCA2 mutations must also consider risk-reducing salpingo-oophorectomy (RRSO) and how to coordinate this procedure with their breast surgery. We report the factors associated with coordinated versus sequential surgery and compare the outcomes of each. Patients in our cancer risk database who had breast cancer and a known deleterious BRCA1/2 mutation before undergoing breast surgery were included. Women who chose concurrent RRSO at the time of breast surgery were compared to those who did not. Sixty-two patients knew their mutation carrier status before undergoing breast cancer surgery. Forty-three patients (69%) opted for coordinated surgeries, and 19 (31%) underwent sequential surgeries at a median follow-up of 4.4 years. Women who underwent coordinated surgery were significantly older than those who chose sequential surgery (median age of 45 vs. 39 years; P = .025). There were no differences in comorbidities between groups. Patients who received neoadjuvant chemotherapy were more likely to undergo coordinated surgery (65% vs. 37%; P = .038). Sequential surgery patients had longer hospital stays (4.79 vs. 3.44 days, P = .01) and longer operating times (8.25 vs. 6.38 hours, P = .006) than patients who elected combined surgery. Postoperative complications were minor and were no more likely in either group (odds ratio, 4.76; 95% confidence interval, 0.56-40.6). Coordinating RRSO with breast surgery is associated with receipt of neoadjuvant chemotherapy, longer operating times, and hospital stays without an observed increase in complications. In the absence of risk, surgical options can be personalized. Copyright © 2016 Elsevier Inc. All rights reserved.

Healthcare providers' caring: Nothing is too small for parents and children hospitalized for heart surgery.

PubMed

Wei, Holly; Roscigno, Cecelia I; Swanson, Kristen M

Parents of children with congenial heart disease (CHD) face frequent healthcare encounters due to their child's care trajectory. With an emphasis on assuring caring in healthcare, it is necessary to understand parents' perceptions of healthcare providers' actions when their child undergoes heart surgery. To describe parents' perceptions of healthcare providers' actions when their child is diagnosed with CHD and undergoes heart surgery. This is a qualitative study with in-depth interviews. Parents of children with CHD were interviewed twice after surgery. We analyzed data using directed content analysis guided by Swanson Caring Theory. Findings of the study indicate that parents perceive caring when providers seek to understand them (knowing); accompany them physically and emotionally (being with); help them (doing for); support them to be the best parents they can be (enabling); and trust them to care for their child (maintaining belief). Healthcare providers play an irreplaceable role in alleviating parents' emotional toll when their child undergoes cardiac surgery. Providers' caring is an integral component in healthcare.

As the efficacy of surgical ablation for atrial fibrillation (AF) is reported to be suboptimal for patients with a giant left atrium (LA), its routine use on this population has remained controversial. We sought to evaluate the clinical outcomes of patients with a giant LA undergoing mitral valve (MV) surgery with/without the maze procedure. We identified 759 patients with a giant LA (>60 mm) and AF undergoing MV surgery from 1999 through 2012. Of these, 400 underwent MV surgery with the maze procedure (maze group), and the remainder (n=359) underwent MV surgery only (no-maze group). To reduce the impact of selection bias, propensity score analyses were performed based on 25 baseline covariates. Early death occurred in five (1.3%) and nine (2.5%) patients in the maze and the no-maze group, respectively (p=0.28). Freedom from AF at 5 years was 68.9% in the maze group and 9.6% in the no-maze group (p<0.001). After adjustment, the maze group showed a significantly lower risk of death (HR, 0.65; 95% CI 0.44 to 0.98; p=0.038), thromboembolic events (HR, 0.23; 95% CI 0.09 to 0.58; p=0.002) and composite adverse outcomes (death, congestive heart failure and valve-related complications; HR, 0.55; 95% CI 0.42 to 0.71; p<0.001) than the no-maze group. In subgroup analyses, MV surgery with the maze procedure resulted in higher survival and event-free survival in most risk subgroups than without the maze procedure. The concomitant maze procedure improved postoperative rhythm status, clinical outcomes and cardiac functions in patients with a giant LA undergoing MV surgery. This study indicates that the patients with a giant LA undergoing MV surgery may benefit from an addition of the maze procedure. Published by the BMJ Publishing Group Limited.

Abstract Objective: To construct a clinical decision support system (CDSS) for undergoing surgery based on domain ontology and rules reasoning in the setting of hospitalized diabetic patients. Materials and Methods: The ontology was created with a modified ontology development method, including specification and conceptualization, formalization, implementation, and evaluation and maintenance. The Protégé–Web Ontology Language editor was used to implement the ontology. Embedded clinical knowledge was elicited to complement the domain ontology with formal concept analysis. The decision rules were translated into JENA format, which JENA can use to infer recommendations based on patient clinical situations. Results: The ontology includes 31 classes and 13 properties, plus 38 JENA rules that were built to generate recommendations. The evaluation studies confirmed the correctness of the ontology, acceptance of recommendations, satisfaction with the system, and usefulness of the ontology for glycemic management of diabetic patients undergoing surgery, especially for domain experts. Conclusions: The contribution of this research is to set up an evidence-based hybrid ontology and an evaluation method for CDSS. The system can help clinicians to achieve inpatient glycemic control in diabetic patients undergoing surgery while avoiding hypoglycemia. PMID:24730353

Background We hypothesized that patients undergoing surgery for colorectal cancer (CRC) with COPD as a comorbidity would consume more resources and have worse in-hospital outcomes than similar patients without COPD. Therefore, we compared different aspects of the care process and short-term outcomes in patients undergoing surgery for CRC, with and without COPD. Methods This was a prospective study and it included patients from 22 hospitals located in Spain – 472 patients with COPD and 2,276 patients without COPD undergoing surgery for CRC. Clinical variables, postintervention intensive care unit (ICU) admission, use of invasive mechanical ventilation, and postintervention antibiotic treatment or blood transfusion were compared between the two groups. The reintervention rate, presence and type of complications, length of stay, and in-hospital mortality were also estimated. Hazard ratio (HR) for hospital mortality was estimated by Cox regression models. Results COPD was associated with higher rates of in-hospital complications, ICU admission, antibiotic treatment, reinterventions, and mortality. Moreover, after adjusting for other factors, COPD remained clearly associated with higher and earlier in-hospital mortality. Conclusion To reduce in-hospital morbidity and mortality in patients undergoing surgery for CRC and with COPD as a comorbidity, several aspects of perioperative management should be optimized and attention should be given to the usual comorbidities in these patients.

The purpose of this study was to identify the incidence, causes and impact of non-adherence to oral and subcutaneous chronic treatments for patients with polycythemia vera or essential thrombocythemia. Patients receiving cytoreductive drugs for polycythemia vera or essential thrombocythemia were recruited at our institution ( Observatoire Brestois des Néoplasies Myéloprolifératives registry). They completed a one-shot questionnaire designed by investigators ( Etude de l'Observance Thérapeutique et des Effets Secondaires des Traitements study). Data about complications (thrombosis, transformation and death) at any time in the patient's life (before diagnosis, up until consultation and after the completion of the questionnaire) were collected. Sixty-five (22.7%) of 286 patients reported poor adherence (<90%) to their treatment with cytoreductive drugs and 46/255/18%) also declared non-adherence to antithrombotic drugs. In total, 85/286 patients (29.7%) declared they did not adhere to their treatment. Missing an intake was rare and was mostly due to forgetfulness especially during occupational travel and holidays. Patients who did not adhere to their treatment were characterized by younger age, living alone, having few medications but a high numbers of pills and determining their own schedule of drug intake. Having experienced thrombosis or hematologic evolution did not influence the adherence rate. Non-adherence to oral therapy was associated with a higher risk of phenotypic evolution (7.3 versus 1.8%, P =0.05). For patients treated for polycythemia vera or essential thrombocythemia, non-adherence to cytoreductive and/or antithrombotic therapies is frequent and is influenced by age, habitus and concomitant treatments, but not by disease history or treatment side effects. Phenotypic evolution seems to be more frequent in the non-adherent group. Copyright© 2018 Ferrata Storti Foundation.

Post-bariatric surgery body contouring in the NHS: a survey of UK bariatric surgeons.

Highton, Lyndsey; Ekwobi, Chidi; Rose, Victoria

2012-04-01

Following massive weight loss, patients are left with folds of redundant skin that may cause physical and psychological problems. These problems can be addressed through body contouring procedures such as abdominoplasty and the thigh lift. Despite an exponential rise in the number of bariatric surgery procedures performed in the United Kingdom, there are no national guidelines on the provision of body contouring procedures after massive weight loss. We conducted a survey of UK Bariatric Surgeons to determine the pre-operative counselling that patients receive on this issue, their opinions towards post-bariatric surgery body contouring and current referral patterns to Plastic Surgery. By exploring the relationship between Bariatric and Plastic Surgery, we aimed to identify how the comprehensive treatment of patients undergoing bariatric surgery could be improved. A questionnaire was sent to 86 surgeon members of the British Obesity and Metabolic Surgery Society. Questionnaires were analysed from the 61/86 respondents (71% response rate). 92% of the responding surgeons feel that patients face functional problems relating to skin redundancy after massive weight loss, and a high percentage of patients complain about this problem. However, only 66% of surgeons routinely counsel patients about these problems before they undergo bariatric surgery. 96% of respondents feel that body contouring for these patients should be funded on the NHS in selected cases. However, it is difficult for patients to access consultation with a Plastic Surgeon and there are no explicit guidelines on the criteria that patients must fulfil to undergo body contouring surgery on the NHS. At present, these criteria are locally determined and represent a postcode lottery. The NICE guidelines on obesity recommend that patients undergoing bariatric surgery should have information on, or access to plastic surgery where appropriate, but this standard is not being achieved. National guidelines on post-bariatric body contouring surgery are needed to improve the comprehensive treatment of these patients. The clinical and cost effectiveness of bariatric surgery has been well established. Further studies focussing on the outcome of body contouring after massive weight loss could support this becoming and integral part of the bariatric surgery pathway.

Cardiac surgery is a highly complex procedure which generates worsening of lung function and decreased inspiratory muscle strength. The inspiratory muscle training becomes effective for muscle strengthening and can improve functional capacity. To investigate the effect of inspiratory muscle training on functional capacity submaximal and inspiratory muscle strength in patients undergoing cardiac surgery. This is a clinical randomized controlled trial with patients undergoing cardiac surgery at Instituto Nobre de Cardiologia. Patients were divided into two groups: control group and training. Preoperatively, were assessed the maximum inspiratory pressure and the distance covered in a 6-minute walk test. From the third postoperative day, the control group was managed according to the routine of the unit while the training group underwent daily protocol of respiratory muscle training until the day of discharge. 50 patients, 27 (54%) males were included, with a mean age of 56.7±13.9 years. After the analysis, the training group had significant increase in maximum inspiratory pressure (69.5±14.9 vs. 83.1±19.1 cmH2O, P=0.0073) and 6-minute walk test (422.4±102.8 vs. 502.4±112.8 m, P=0.0031). We conclude that inspiratory muscle training was effective in improving functional capacity submaximal and inspiratory muscle strength in this sample of patients undergoing cardiac surgery.

Clinical predictors of perioperative mortality in geriatric patients undergoing emergent general surgery have not been well described. The purpose of this study was to determine the incidence of postoperative morbidity and mortality in geriatric patients and factors associated with mortality. A retrospective review of patients 65 years of age or older undergoing emergent general surgery at a public teaching hospital was performed over a 7-year period. Data collected included demographics, comorbidities, laboratory studies, perioperative morbidities, and mortality. Descriptive statistics and predictors of morbidity and mortality are described. The mean age was 74 years. Indications for surgery included small bowel obstruction (24%), diverticulitis (20%), perforated viscous (16%), and large bowel obstruction (9%). The overall complication rate was 41 per cent with six cardiac complications (14%) and seven perioperative (16%) deaths. Mean admission serum creatinine was significantly higher in patients who died (3.6 vs 1.5 mg/dL, P = 0.004). Mortality for patients with an admission serum creatinine greater than 2.0 mg/dL was 42 per cent (5 of 12) compared with 3 per cent (2 of 32) for those 2.0 mg/dL or less (OR, 10.7; CI, 1.7 to 67; P = 0.01). Morbidity and mortality in geriatric patients undergoing emergency surgery remains high with the most significant predictor of mortality being the presence of renal insufficiency on admission.

Background Among the traditional systems of medicine practiced all over the world, Ayurveda and Yoga has a documented history dating back to beyond 200 BC. Robotic and video assisted thoracic surgery (VATS) is an invention of the 21st century. We aim to quantify the effects of integration of Ayurveda and Yoga on patients undergoing minimally invasive robotic and VATS. Methods Four hundred and fifty-four patients undergoing VATS and robotic thoracic surgery were introduced to a pre and postoperative protocol of Yoga therapy, mediation and oil massages. Yoga exercises included Pranayam, Anulom Vilom, and Oil Massages included Urotarpan. Preoperative and postoperative respiratory functions were recorded. Patient satisfaction questionnaire were noted. Statistical comparison was made to control group undergoing minimally invasive thoracic surgery without integrative medicine. Only one patient refused to undergo Ayurveda therapy and was deleted from the group. Results Acceptability was high among all patients. Preoperative training led to implementation as early as 6 hours post surgery. Pulmonary function test showed significant improvement. All patients suggested an improvement in satisfaction score. Pain score were less in study patients. Quicker mobilization led to early discharge and drain removal. Chronic pain was prevented in patients having oil massages over the healed wound sites. Conclusions Integration of Ayurveda, Yoga and minimally invasive robotic and VATS is acceptable to Indian patients and gives better clinical results and higher patient satisfaction. PMID:26941975

Cross-sectional study. To investigate the factors associated with work ability in patients undergoing surgery for cervical radiculopathy. Surgery is a common treatment of cervical radiculopathy in people of working age. However, few studies have investigated the impact on the work ability of these patients. Patients undergoing surgery for cervical radiculopathy (n = 201) were recruited from spine centers in Sweden to complete a battery of questionnaires and physical measures the day before surgery. The associations between various individual, psychological, and work-related factors and self-reported work ability were investigated by Spearman rank correlation coefficient, multivariate linear regression, and forward stepwise regression analyses. Factors that were significant (P < 0.05) in each statistical analysis were entered into the successive analysis to reveal the factors most related to work ability. Work ability was assessed using the Work Ability Index. The mean Work Ability Index score was 28 (SD, 9.0). The forward stepwise regression analysis revealed 6 factors significantly associated with work ability, which explained 62% of the variance in the Work Ability Index. Factors highly correlated with greater work ability included greater self-efficacy in performing self-cares, lower physical load on the neck at work, greater self-reported chance of being able to work in 6 months' time, greater use of active coping strategies, lower frequency of hand weakness, and higher health-related quality of life. Psychological, work-related and individual factors were significantly associated with work ability in patients undergoing surgery for cervical radiculopathy. High self-efficacy was most associated with greater work ability. Consideration of these factors by surgeons preoperatively may provide optimal return to work outcomes after surgery. 3.

Interdisciplinary management of elderly patients requiring spine surgery has been shown to improve short- and long-term outcomes. The aim of this study was to determine whether an interdisciplinary team approach mitigates use of intensive care unit (ICU) resources. A unique comanagement model for elderly patients undergoing lumbar fusion surgery was implemented at a major academic medical center. The Peri-operative Optimization of Senior Health Program (POSH) was launched with the aim of improving outcomes in elderly patients (>65 years old) undergoing complex lumbar spine surgery. In this model, a geriatrician evaluates elderly patients preoperatively, comanages daily throughout hospital course, and coordinates multidisciplinary rehabilitation, along with the neurosurgical team. We retrospectively reviewed the first 100 cases after the initiation of the POSH protocol and compared them with the immediately preceding 25 cases to assess the rates of ICU transfer and independent predictors of ICU admission. A total of 125 patients undergoing lumbar decompression and fusion surgery were enrolled in this pilot program. Baseline characteristics and intraoperative variables, as well as number of fusion levels and duration of surgery, were similar between both cohorts. There was a significant difference in the use of ICU services (ICU admission rates) between both cohorts, with the non-POSH cohort having a 3-fold increase compared with the POSH cohort (P < 0.0001). In a multivariate analysis, lack of an interdisciplinary comanagement team approach was an independent predictor for ICU transfers in elderly patients undergoing corrective surgery (odds ratio 8.51, 95% confidence interval 2.972-24.37, P < 0.0001). Our study suggests that an interdisciplinary comanagement model between geriatrics and neurosurgery is independently associated with reduced use of critical care services.

Gastric cancer surgery is increasingly being centralized in the Netherlands, whereas the diagnosis is often made in hospitals where gastric cancer surgery is not performed. The aim of this study was to assess whether hospital of diagnosis affects the probability of undergoing surgery and its impact on overall survival. All patients with potentially curable gastric cancer according to stage (cT1/1b-4a, cN0-2, cM0) diagnosed between 2005 and 2013 were selected from The Netherlands Cancer Registry. Multilevel logistic regression was used to examine the probability of undergoing surgery according to hospital of diagnosis. The effect of variation in probability of undergoing surgery among hospitals of diagnosis on overall survival during the intervals 2005-2009 and 2010-2013 was examined by using Cox regression analysis. A total of 5620 patients with potentially curable gastric cancer, diagnosed in 91 hospitals, were included. The proportion of patients who underwent surgery ranged from 53.1 to 83.9 per cent according to hospital of diagnosis (P < 0.001); after multivariable adjustment for patient and tumour characteristics it ranged from 57.0 to 78.2 per cent (P < 0.001). Multivariable Cox regression showed that patients diagnosed between 2010 and 2013 in hospitals with a low probability of patients undergoing curative treatment had worse overall survival (hazard ratio 1.21; P < 0.001). The large variation in probability of receiving surgery for gastric cancer between hospitals of diagnosis and its impact on overall survival indicates that gastric cancer decision-making is suboptimal. © 2015 BJS Society Ltd Published by John Wiley & Sons Ltd.

Adults with hemophilia A (HA), hemophilia B (HB), and von Willebrand disease (VWD) frequently require surgery and invasive procedures. However, there is variability in perioperative management guidelines. We describe our periprocedural outcomes in this setting. A retrospective chart review from January 2006 to December 2012 of patients with HA, HB, and VWD undergoing surgery or invasive procedures was conducted. Type of procedures, management including the use of continuous factor infusion, and administration of antifibrinolytics were reviewed. Adverse outcomes were defined as acute bleeding (<48 hours), delayed bleeding (≥48 hours), transfusion, inhibitor development, and thrombosis. We identified 59 patients with HA and HB. In all, 24 patients had severe hemophilia and 12 had mild/moderate hemophilia. Twelve patients had inhibitors. There were also 5 female carriers of HA and 6 patients with VWD. There were 34 major surgeries (26 orthopedic, 8 nonorthopedic) and 129 minor surgeries. Continuous infusion was used in 55.9% of major surgeries versus 8.5% of minor surgeries. Antifibrinolytics were administered in 14.7% of major surgeries versus 23.2% of minor surgeries. In all, 4 patients developed acute bleeding and 10 patients developed delayed bleeding. Delayed bleeding occurred in 28.6% of genitourinary procedures and in 16.1% of dental procedures. Five patients acquired an inhibitor and 2 had thrombosis. In conclusion, patients with HA, HB, or VWD had similar rates of adverse outcomes when undergoing minor surgeries or major surgeries. This finding underscores the importance of an interdisciplinary management and procedure-specific guidelines for patients with hemophilia and VWD prior to even minor invasive procedures.

To compare analgesic and adverse effects of ketoprofen and carprofen when used to control pain associated with elective orthopedic surgeries in dogs. Prospective randomized clinical trial. 93 client-owned dogs: 46 undergoing reconstruction of the cranial cruciate ligament, 47 undergoing femoral head and neck excision, and 15 control dogs anesthetized for radiographic procedures. Dogs undergoing surgery were randomly given ketoprofen, carprofen, or saline (0.9% NaCl) solution, SC, prior to surgery. Pain score and serum cortisol concentration were recorded for 12 hours after surgery for all dogs. When pain score was > or = 7, oxymorphone was administered i.m. Bleeding time was measured prior to and during surgery. The proportion of dogs that required oxymorphone was significantly higher for the carprofen and placebo groups than for the ketoprofen group. Pain score for the placebo group was significantly higher than for the ketoprofen and carprofen groups, 2, 8, and 9 hours after surgery. Cortisol concentration was significantly higher for the placebo group than for the carprofen group at 4 and 6 hours after surgery. Significant differences were not detected between ketoprofen and carprofen groups with respect to pain score and cortisol concentration. Bleeding time was significantly longer for the ketoprofen group than for the other groups during surgery. One dog treated with ketoprofen developed a hematoma at the surgical site. Ketoprofen and carprofen given prior to surgery were effective for postoperative pain relief in dogs. However, ketoprofen should not be used when noncompressible bleeding may be a problem.

The use of laparoscopy in trauma is, in general, limited for diagnostic purposes. We aim to evaluate the therapeutic role of laparoscopic surgery in trauma patients. We analyzed the National Trauma Data Bank (2007 to 2010) for all patients undergoing diagnostic laparoscopy. Patients undergoing a therapeutic laparoscopic surgical procedure were identified and tabulated. Mortality and hospital length of stay for patients with isolated abdominal injuries were compared between the open and laparoscopic groups. Of a total of 2,539,818 trauma visits in the National Trauma Data Bank, 4,755 patients underwent a diagnostic laparoscopy at 467 trauma centers. Of these, 916 (19.3%) patients underwent a therapeutic laparoscopic intervention. Common laparoscopic operations included diaphragm repair, bowel repair or resection, and splenectomy. Patients undergoing laparoscopic surgery had a significantly shorter length of stay than the open group (5 vs 6 days; P < .001). Therapeutic laparoscopic surgery for trauma is feasible and may provide better outcomes. Copyright © 2015 Elsevier Inc. All rights reserved.

To evaluate the clinical efficacy of intravenous (IV) fluid warming in patients undergoing laparoscopic colorectal surgery. Adult patients undergoing laparoscopic colorectal surgery were randomly assigned to receive either IV fluids at room temperature (control group) or warmed IV fluids (warm fluids group). Each patient received a standardized goal-directed fluid regimen based on stroke volume variances. Oesophageal temperature was measured at 15 min intervals for 2 h after induction of anaesthesia. A total of 52 patients were enrolled in the study. The drop in core temperature in the warm fluids group was significantly less than in the control group 2 h after the induction of anaesthesia. This significant difference was seen from 30 min after induction. IV fluid warming was associated with a smaller drop in core temperature than room temperature IV fluids in laparoscopic colorectal surgery incorporating goal-directed fluid therapy. © The Author(s) 2016.

The aim of this study was to use machine learning to predict abdominal recurrence on CT on the basis of serial cancer antigen 125 (CA125) levels in patients with advanced high-grade serous ovarian cancer on surveillance. This institutional review board-approved, HIPAA-compliant, retrospective, hypothesis-generating study included all 57 patients (mean age, 61 ± 11.2 years) with advanced high-grade serous ovarian cancer who underwent cytoreductive surgery from January to December 2012, followed by surveillance abdominopelvic CT and corresponding CA125 levels. A blinded radiologist reviewed abdominopelvic CT studies until recurrence was noted. Four measures of CA125 were assessed: actual CA125 levels at the time of CT, absolute change since prior CT, relative change since prior CT, and rate of change since prior CT. Using machine learning, support vector machine models were optimized and evaluated using 10-fold cross-validation to determine the CA125 measure most predictive of abdominal recurrence. The association of the most accurate CA125 measure was further analyzed using Cox proportional-hazards model along with age, tumor size, stage, and degree of cytoreduction. Rate of change in CA125 was most predictive of abdominal recurrence in a linear kernel support vector machine model and was significantly higher preceding CT studies showing abdominal recurrence (median 13.2 versus 0.6 units/month; P = .007). On multivariate analysis, a higher rate of CA125 increase was significantly associated with recurrence (hazard ratio, 1.02 per 10 units change; 95% confidence interval, 1.0006-1.04; P = .04). A higher rate of CA125 increase is associated with abdominal recurrence. The rate of increase of CA125 may help in the selection of patients who are most likely to benefit from abdominopelvic CT in surveillance of ovarian cancer.

The standard management for advanced-stage epithelial ovarian cancer is optimum cytoreductive surgery followed by platinum based chemotherapy. However, retroperitoneal lymph node resection remains controversial. The multiple directions of the lymph drainage pathway in ovarian cancer have been recognized. The incidence and pattern of lymph node involvement depends on the extent of the disease and the histological type. Several published cohorts suggest the survival benefit of pelvic and para-aortic lymphadenectomy. A recent large randomized trial have demonstrated the potential benefit for surgical removal of bulky lymph nodes in term of progression-free survival but failed to show any overall survival benefit because of a critical methodology. Further randomised trials are needed to balance risks and benefits of systematic lymphadenectomy in advanced-stage disease. CARACO is a French ongoing trial, built to bring a reply to this important question. A huge effort for inclusion of the patients, and involving new teams, are mandatory.

Ovarian cancer often presents at an advanced stage, but tends to be an intra-peritoneal disease that respects peritoneal planes. Thus, colo-rectal perforation of the tumor is an extremely rare presentation. The surgical treatment of malignant colo-ovarian fistula should include complete cyto-reduction at the same time as the treatment of the fistula. However, prognosis remains poor, because of the advanced stage of neoplasia. We report the case of a patient with an ovarian malignant tumor perforating into the recto-sigmoid colon. CT scan was the cornerstone of the radiological diagnosis. We managed to perform a complete cyto-reduction, including an en-bloc resection of the uterus, the mass, adnexa and recto-sigmoid with removal of the associated pelvic abscess.

Study Objective To evaluate if the administration of intraperitoneal bupivacaine decreased postoperative pain in patients undergoing minimally invasive gynecologic and gynecologic cancer surgery. Design Retrospective cohort study (Canadian Task Force classification II-3). Setting University-based gynecologic oncology practice operating at a tertiary medical center. Patients All patients on the gynecologic oncology service undergoing minimally invasive surgery between September 2011 and June 2013. Interventions Starting August 2012, intraperitoneal administration of .25% bupivacaine was added to all minimally invasive surgeries. These patients were compared with historical control subjects who had surgery between September 2011 and July 2012 but did not receive intraperitoneal bupivacaine. Measurements and Main Results One-hundred thirty patients were included in the study. The patients who received intraperitoneal bupivacaine had lower median narcotic use on the day of surgery and the first postoperative day compared with those who did not receive intraperitoneal bupivacaine (day 0: 7.0 mg morphine equivalents vs 11.0 mg, p = .007; day 1: .3 mg vs 1.7 mg, p = .0002). The median patient-reported pain scores were lower on the day of surgery in the intraperitoneal bupivacaine group (2.7 vs 3.2, p = .05) Conclusions The administration of intraperitoneal bupivacaine was associated with improved postoperative pain control in patients undergoing minimally invasive gynecologic and gynecologic cancer surgery and should be further evaluated in a prospective study.

Management of the axilla in patients with early-stage breast cancer (ESBC) has evolved. Recent trials support less extensive axillary surgery in patients undergoing mastectomy. We examine factors affecting regional lymph node (RLN) surgery and outcomes in patients with ESBC undergoing mastectomy. Women with clinical T1/2 N0 M0 invasive BC who underwent mastectomy with 1-2 positive nodes were selected from the National Cancer Database (2004-2015). Axillary surgery was defined by number of RLNs examined: 1-5 sentinel LN dissection (SLND), and ≥ 10 axillary LND (ALND). Binary logistic regression and survival analyses were performed to assess the association between axillary surgery and clinical characteristics, and overall survival (OS), respectively. 34,243 patients were included: 13,821 SLND (40%) and 20,422 ALND (60%). SLND significantly increased from 21% (2004) to 45% (2015) (p < .001). Independent factors associated with SLND were treatment year, non-Academic centers, geographic region, tumor histology, and postmastectomy radiotherapy (PMRT). Multivariable survival analysis showed that ALND was associated with better OS (HR 0.78, 95% CI 0.72-0.83, p < .001) relative to SLND; however, there was no difference in patients with LN micrometastases treated without RT (HR 0.87, 95% CI 0.73-1.05, p = .153) or patients receiving PMRT (HR 0.92, 95% CI 0.76-1.13, p = .433). SLND has significantly increased in patients undergoing mastectomy with limited axillary disease and is influenced by patient, tumor, and treatment factors. Survival outcomes did not differ by axillary treatment for patients with LN micrometastases treated without RT or patients who received PMRT. SLND may be considered in select patients with ESBC and limited axillary disease undergoing mastectomy.

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.

Background Few studies evaluated the association between nutritional disorders, quality of life and weight loss in patients undergoing bariatric surgery. Aim To identify nutritional changes in patients undergoing bariatric surgery and correlate them with weight loss, control of comorbidities and quality of life. Method A prospective cohort, analytical and descriptive study involving 59 patients undergoing bariatric surgery was done. Data were collected preoperatively at three and six months postoperatively, evaluating nutritional aspects and outcomes using BAROS questionnaire. The data had a confidence interval of 95%. Results The majority of patients was composed of women, 47 (79.7%), with 55.9% of the series with BMI between 40 to 49.9 kg/m². In the sixth month after surgery scores of quality of life were significantly higher than preoperatively (p<0.05) and 27 (67.5 %) patients had comorbidities resolved, 48 (81.3 %) presented BAROS scores of very good or excellent. After three and six months of surgery 16 and 23 presented some nutritional disorder, respectively. There was no relationship between the loss of excess weight and quality of life among patients with or without nutritional disorders. Conclusions Nutritional disorders are uncommon in the early postoperative period and, when present, have little or no influence on quality of life and loss of excess weight. PMID:25861070

Although stapling is an alternative to hand-suturing in gastrointestinal surgery, recent trials specifically designed to evaluate differences between the two in surgery time, anastomosis time, and return to bowel activity are lacking. This trial compared the outcomes of the two in subjects undergoing open gastrointestinal surgery. Adult subjects undergoing emergency or elective surgery requiring a single gastric, small, or large bowel anastomosis were enrolled into this open-label, prospective, randomized, interventional, parallel, multicenter, controlled trial. Randomization was assigned in a 1:1 ratio between the hand-sutured group (n = 138) and the stapled group (n = 142). Anastomosis time, surgery time, and time to bowel activity were collected and compared as primary endpoints. A total of 280 subjects were enrolled from April 2009 to September 2010. Only the time of anastomosis was significantly different between the two arms: 17.6 ± 1.90 min (stapled) and 20.6 ± 1.90 min (hand-sutured). This difference was deemed not clinically or economically meaningful. Safety outcomes and other secondary endpoints were similar between the two arms. Mechanical stapling is faster than hand-suturing for the construction of gastrointestinal anastomoses. Apart from this, stapling and hand-suturing are similar with respect to the outcomes measured in this trial.

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.

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 relationship between the transfusion of red blood cell (RBC) units and outcomes in patients undergoing cardiac surgery is the subject of intense debates. In this study, we investigated the relationship between the transfusion of 1-2 leucocyte-depleted (LD) RBC units and outcomes in patients undergoing open-heart valve surgery. The investigation encompassed consecutive patients undergoing open-heart valve surgery at our institution between July 2009 and March 2015 who received no (RBC- group) or 1-2 units of LD RBC (RBC+ group). End-points were 30-day mortality (primary), the incidence of in-hospital major organ dysfunctions and 1-year mortality (secondary). Propensity score (PS)-adjusted statistical analysis was used to assess the effect of RBC transfusion on end-points. Thirty-day mortality rate was 0.2% (3/1485) in the RBC- group and 0.4% (6/1672) in the RBC+ group, with a PS-adjusted odds ratio (OR) for 30-day mortality of 1.00 (95% CI: 0.21-4.83;P = 0.99). The two groups showed no significant differences in PS-adjusted ORs for major complications, such as stroke, low cardiac output syndrome, thoracic wound infection and prolonged mechanical ventilation (>24 h). The PS-adjusted ORs for prolonged intensive care unit stay (>48 h) were, however, significantly higher in the RBC+ group (OR = 1.34 [95%CI: 1.04-1.72; P = 0.02]) than in the RBC- group. One-year mortality was comparable between groups (PS-adjusted hazard ratio for the RBC+ group: 0.85 [95% CI: 0.42-1.72; P = 0.65]). Our data do not provide evidence that in patients undergoing valve surgery with cardiopulmonary bypass, transfusion of 1-2 units of LD RBC increases operative mortality, the incidence of postoperative complications or 1-year mortality. © The Author 2016.

Purpose: To analyze the outcomes of therapy and identify prognostic factors for patients treated with surgery followed by intraoperative radiotherapy (IORT) for gynecologic malignancies at a single institution. Methods and Materials: We performed a retrospective review of 36 consecutive patients treated with IORT to 44 sites with mean follow-up of 50 months. The primary site was the cervix in 47%, endometrium in 31%, vulva in 14%, vagina in 6%, and fallopian tubes in 3%. Previous RT had failed in 72% of patients, and 89% had recurrent disease. Of 38 IORT sessions, 84% included maximal cytoreductive surgery, including 18% exenterations. Themore » mean age was 52 years (range, 30-74), mean tumor size was 5 cm (range, 0.5-12), previous disease-free interval was 32 months (range, 0-177), and mean IORT dose was 1,152 cGy (range, 600-1,750). RT and systemic therapy after IORT were given to 53% and 24% of the cohort, respectively. The outcomes measured were locoregional control (LRC), distant metastasis-free survival (DMFS), disease-specific survival (DSS), and treatment-related complications. Results: The Kaplan-Meier 5-year LRC, DMFS, and DSS probability for the whole group was 44%, 51%, and 47%, respectively. For cervical cancer patients, the Kaplan-Meier 5-year LRC, DMFS, and DSS estimate was 45%, 60%, and 46%, respectively. The prognostic factors found on multivariate analysis (p {<=} 0.05) were the disease-free interval for LRC, tumor size for DMFS, and cervical primary, previous surgery, and locoregional relapse for DSS. Our cohort had 10 Grade 3-4 complications associated with treatment (surgery and IORT) and a Kaplan-Meier 5-year Grade 3-4 complication-free survival rate of 72%. Conclusions: Survival for pelvic recurrence of gynecologic cancer is poor (range, 0-25%). IORT after surgery seems to confer long-term local control in carefully selected patients.« less

Postoperative cardiocerebral and renal complications are a major threat for patients undergoing cardiac surgery. This study was aimed to examine the effect of preoperative aspirin use on patients undergoing cardiac surgery. An observational cohort study was performed on consecutive patients (n = 1879) receiving cardiac surgery at this institution. The patients excluded from the study were those with preoperative anticoagulants, unknown aspirin use, or underwent emergent cardiac surgery. Outcome events included were 30-day mortality, renal failure, readmission and a composite outcome--major adverse cardiocerebral events (MACE) that include permanent or transient stroke, coma, perioperative myocardial infarction (MI), heart block and cardiac arrest. Of all patients, 1145 patients met the inclusion criteria and were divided into two groups: those taking (n = 858) or not taking (n = 287) aspirin within 5 days preceding surgery. Patients with aspirin presented significantly more with history of hypertension, diabetes, peripheral arterial disease, previous MI, angina and older age. With propensity scores adjusted and multivariate logistic regression, however, this study showed that preoperative aspirin therapy (vs. no aspirin) significantly reduced the risk of MACE (8.4% vs. 12.5%, odds ratio [OR] 0.585, 95% CI 0.355-0.964, P = 0.035), postoperative renal failure (2.6% vs. 5.2%, OR 0.438, CI 0.203-0.945, P = 0.035) and dialysis required (0.8% vs. 3.1%, OR 0.230, CI 0.071-0.742, P = 0.014), but did not significantly reduce 30-day mortality (4.1% vs. 5.8%, OR 0.744, CI 0.376-1.472, P = 0.396) nor it increased readmissions in the patients undergoing cardiac surgery. Preoperative aspirin therapy is associated with a significant decrease in the risk of MACE and renal failure and did not increase readmissions in patients undergoing non-emergent cardiac surgery.

Postoperative atrial fibrillation is a major cause of morbidity and mortality for stroke after cardiac surgery. Both systemic inflammation and oxidative stress play a role in the initiation of postoperative atrial fibrillation after cardiac surgery. The possible association between long-term intake of antioxidant-rich foods and postoperative atrial fibrillation incidence was examined in patients undergoing cardiac surgery. A total of 217 consecutive patients (74% were men; median age, 68.4 years) undergoing cardiac surgery, mainly coronary artery bypass grafting and valve replacement or repair, were recruited from January 2010 to September 2012. Total antioxidant capacity was measured in foods by the Trolox equivalent antioxidant capacity assay. The European Prospective Investigation into Cancer and Nutrition Food Frequency Questionnaire was used for dietary total antioxidant capacity assessment. The association among tertiles of dietary total antioxidant capacity and postoperative atrial fibrillation incidence was assessed using multivariable logistic analysis. The overall incidence of total arrhythmias and postoperative atrial fibrillation was 42.4% and 38.2%, respectively. In multivariable analysis, after adjustment for age, gender, use of hypoglycemic drugs, physical activity, education, previous diagnosis of atrial fibrillation, and total energy intake, patients in the highest tertile of dietary total antioxidant capacity had a lower risk of postoperative atrial fibrillation than patients in the 2 lowest tertiles (odds ratio, 0.46; 95% confidence interval, 0.22-0.95; P = .048). A restricted cubic spline transformation confirmed the nonlinear relationship between total antioxidant capacity (in continuous scale) and postoperative atrial fibrillation (P = .023). When considering only coronary artery bypass grafting, valve replacement/repair, and combined surgeries, the protective effect on postoperative atrial fibrillation of a diet rich in antioxidants was confirmed. Long-term consumption of antioxidant-rich foods is associated with a reduced incidence of postoperative atrial fibrillation in patients undergoing cardiac surgery.

While the neuroprotective benefits of estrogen and progesterone in critical illness are well established, the data regarding the effects of androgens are conflicting. Surgical repair of congenital heart disease is associated with significant morbidity and mortality, but there are scant data regarding the postoperative metabolism of sex steroids in this setting. The objective of this prospective observational study was to compare the postoperative sex steroid patterns in pediatric patients undergoing major cardiac surgery (MCS) versus those undergoing less intensive non-cardiac surgery. Urinary excretion rates of estrogen, progesterone, and androgen metabolites (μg/mmol creatinine/m(2) body surface area) were determined in 24-h urine samples before and after surgery using gas chromatography-mass spectrometry in 29 children undergoing scheduled MCS and in 17 control children undergoing conventional non-cardiac surgery. Eight of the MCS patients had Down's syndrome. There were no significant differences in age, weight, or sex between the groups. Seven patients from the MCS group showed multi-organ dysfunction after surgery. Before surgery, the median concentrations of 17β-estradiol, pregnanediol, 5α-dihydrotestosterone (DHT), and dehydroepiandrosterone (DHEA) were (control/MCS) 0.1/0.1 (NS), 12.4/11.3 (NS), 4.7/4.4 (NS), and 2.9/1.1 (p=0.02). Postoperatively, the median delta 17β-estradiol, delta pregnanediol, delta DHT, and delta DHEA were (control/MCS) 0.2/6.4 (p=0.0002), -3.2/23.4 (p=0.013), -0.6/3.7 (p=0.0004), and 0.5/4.2 (p=0.004). Postoperative changes did not differ according to sex. We conclude that MCS, but not less intensive non-cardiac surgery, induced a distinct postoperative increase in sex steroid levels. These findings suggest that sex steroids have a role in postoperative metabolism following MCS in prepubertal children. Copyright © 2013 Elsevier Ltd. All rights reserved.

In open heart surgery using cardiopulmonary bypass, perfusion of the lower extremities is markedly reduced which may induce critical ischaemia in patients with pre-existing peripheral artery disease. Whether these patients have an increased risk for amputation and should better undergo peripheral revascularization prior to surgery remains unclear. From 1 January 2009 to 31 December 2010, 785 consecutive patients undergoing open heart surgery were retrospectively included. In 443 of these patients, preoperative ankle brachial index (ABI) measurements were available. The cohort was divided into four groups: (i) ABI < 0.5, (ii) ABI 0.5-0.69, (iii) ABI 0.7-0.89 or (iv) ABI ≥ 0.9. Follow-up data of 413 (93.2%) patients were analysed with regard to mortality and amputations. The groups differed significantly in terms of age, cardiac risk factors, performed cardiac surgery and renal function. Postoperative delayed wound healing was significantly associated with lower ABI (25.9, 15.2, 27.0 and 9.6% in Groups I-IV, respectively, P = 0.003), whereas 30-day mortality was not significantly higher in patients with lower ABI (0, 4.3, 8.1 and 3.9%, respectively, P = 0.4). Kaplan-Meier models showed a significantly lower long-term survival over 4 years in patients with reduced ABI (P = 0.001, long-rank test) while amputations occurred rarely with only one minor amputation in Group II (P = 0.023). Patients with reduced ABIs undergoing heart surgery showed more wound-healing disturbances, and higher long-term mortality compared with those with normal ABIs. However, no perioperative ischaemia requiring amputation occurred. Thus, reduced ABIs were not associated with increased peripheral risks in open heart surgery but ABI may be helpful in selecting the site for saphenectomy to potentially avoid delayed healing of related wounds in legs with severely impaired arterial perfusion. © The Author 2015.

The aim of the present study was to investigate changes in emotional state and the relationship between emotional state and demographic/clinical factors and coping style among gynecologic patients undergoing surgery. Using the Japanese version of the Profile of Mood States (POMS), 90 patients (benign disease: 32, malignancy: 58) were examined on three occasions: before surgery, before discharge, and 3 months after discharge. They were also examined using the Coping Inventory for Stressful Situations (CISS) on one occasion before discharge. The scores for the subscales depression, anger, and confusion were the highest after discharge while those for anxiety were the highest before surgery. The average scores of the POMS subscales for all subjects were within the normal range. With regard to the relationship between these emotional states and other factors, multiple regressions showed that the principal determinants of anxiety before surgery were religious belief, psychological symptoms during hospitalization and emotion-oriented (E) coping style; further, it was found that depression after discharge could be explained by chemotherapy, duration of hospitalization, and E coping style. The principal determinants of anger after discharge and vigor before surgery were length of education and E coping style, and severity of disease, chemotherapy, E coping style and task-oriented coping style, respectively. Those of post-discharge fatigue and confusion were length of education, psychological symptoms, and E coping style. In summary it is suggested that the following should be taken into account in patients undergoing gynecologic surgery: anxiety before surgery, depression, anger, and confusion after surgery, including coping styles.

Despite scientific progress with regard to pain neuroscience, perioperative education tends to stick to the biomedical model. This may involve, for example, explaining the surgical procedure or 'back school' (education that focuses on biomechanics of the lumbar spine and ergonomics). Current perioperative education strategies that are based on the biomedical model are not only ineffective, they can even increase anxiety and fear in patients undergoing spinal surgery. Therefore, perioperative pain neuroscience education is proposed as a dramatic shift in educating patients prior to and following surgery for lumbar radiculopathy. Rather than focusing on the surgical procedure, ergonomics or lumbar biomechanics, perioperative pain neuroscience education teaches people about the underlying mechanisms of pain, including the pain they will feel following surgery. The primary objective of the study is to examine whether perioperative pain neuroscience education ('brain school') is more effective than classic back school in reducing pain and improving pain inhibition in patients undergoing surgery for spinal radiculopathy. A secondary objective is to examine whether perioperative pain neuroscience education is more effective than classic back school in: reducing postoperative healthcare expenditure, improving functioning in daily life, increasing return to work, and improving surgical experience (ie, being better prepared for surgery, reducing incongruence between the expected and actual experience) in patients undergoing surgery for spinal radiculopathy. A multi-centre, two-arm (1:1) randomised, controlled trial with 2-year follow-up. People undergoing surgery for lumbar radiculopathy (n=86) in two Flemish hospitals (one tertiary care, university-based hospital and one regional, secondary care hospital) will be recruited for the study. All participants will receive usual preoperative and postoperative care related to the surgery for lumbar radiculopathy. The experimental group will also receive perioperative pain neuroscience education comprising one preoperative and one postoperative individual educational session plus an educational booklet. Participants in the control group will receive perioperative back school on top of usual preoperative and postoperative care, comprising one preoperative and one postoperative individual educational session plus an educational booklet. Self-reported pain and endogenous pain modulation (including measurements of simultaneous cortical activation via electroencephalography) will be the primary outcome measures. Secondary outcome measures will include daily functioning, return to work, postoperative healthcare utilisation and surgical experience/satisfaction. Psychological factors will be measured as possible treatment mediators. All assessments will take place in the week preceding surgery (baseline), and at 3 days and 6 weeks after surgery. Intermediate and long-term follow-up assessments will take place at 6, 12 and 24 months after surgery. All data analyses will be based on the intention-to-treat principle. Repeated measures AN(C)OVA analyses will be used to evaluate and compare treatment effects. Baseline data, treatment centre, age and gender will be included as covariates. Statistical, as well as clinically, significant differences will be evaluated and effect sizes will be determined. In addition, the numbers needed to treat will be calculated. This study will determine whether pain neuroscience education is worthwhile for patients undergoing surgery for lumbar radiculopathy. It is expected that participants who receive perioperative pain neuroscience education will report less pain and have improved endogenous pain modulation, lower postoperative healthcare costs and improved surgical experience. Lower pain and improved endogenous pain modulation after surgery may reduce the risk of developing postoperative chronic pain. Copyright © 2016 Australian Physiotherapy Association.

Rectus sheath block (RSB) is used for postoperative pain relief in patients undergoing abdominal surgery with midline incision. Preoperative RSB has been shown to be effective, but it has not been compared with postoperative RSB. The aim of the present study is to evaluate postoperative pain, sleep quality and changes in the cytokine levels of patients undergoing gynaecological surgery with RSB performed preoperatively versus postoperatively. This study is a prospective, randomised, controlled (randomised, parallel group, concealed allocation), single-blinded trial. All patients undergoing transabdominal gynaecological surgery will be randomised 1:1 to the treatment intervention with general anaesthesia as an adjunct to preoperative or postoperative RSB. The objective of the trial is to evaluate postoperative pain, sleep quality and changes in the cytokine levels of patients undergoing gynaecological surgery with RSB performed preoperatively (n = 32) versus postoperatively (n = 32). All of the patients, irrespective of group allocation, will receive patient-controlled intravenous analgesia (PCIA) with oxycodone. The primary objective is to compare the interval between leaving the post-anaesthesia care unit and receiving the first PCIA bolus injection on the first postoperative night between patients who receive preoperative versus postoperative RSB. The secondary objectives will be to compare (1) cumulative oxycodone consumption at 24 hours after surgery; (2) postoperative sleep quality, as measured using a BIS-Vista monitor during the first night after surgery; and (3) cytokine levels (interleukin-1, interleukin-6, tumour necrosis factor-α and interferon-γ) during surgery and at 24 and 48 hours postoperatively. Clinical experience has suggested that RSB is a very effective postoperative analgesic technique, and we will answer the following questions with this trial. Do preoperative block and postoperative block have the same duration of analgesic effects? Can postoperative block extend the analgesic time? The results of this study could have actual clinical applications that could help to reduce postoperative pain and shorten hospital stays. Current Controlled Trials NCT02477098 15 June 2015.

Our aim was to examine hospital outcomes of coronary artery bypass surgery in patients with and without left ventricular dysfunction, with regard to the surgical technique (off- or on-pump). Between March 2007 and March 2008, 689 consecutive patients underwent isolated first-time coronary artery bypass; 127 had ejection fractions < or = 30% (group 1) and 562 had ejection fractions >30% (group 2). Data of preoperative risk profiles and hospital outcomes were collected prospectively. Off-pump operations were performed in 49 (38.6%) patients in group 1 and 196 (34.9%) in group 2. The incidences of infectious, neurologic, and cardiac complications postoperatively were significantly higher in group 1. In multivariate analysis, preoperative ejection fraction < or = 30% was found to be an independent risk factor for postoperative complications and hospital mortality. The subgroup of patients undergoing off-pump surgery in both groups had a significantly lower rate of total complications than those undergoing conventional on-pump operations, but no significant difference in mortality was observed between those undergoing off-pump or conventional surgery in either group. Off-pump surgery helped to limit the increased morbidity rate after coronary bypass in patients with ventricular dysfunction.

To evaluate perioperative pain in patients undergoing major head and neck cancer surgery and identify associations between preoperative and postoperative pain characteristics. Patients undergoing head and neck surgery with regional/free tissue transfer were enrolled. Preoperative pain and validated screens for symptoms (neuropathic pain, anxiety, depression, fibromyalgia) were assessed. Postoperatively, patients completed a pain diary for 4 weeks. Twenty-seven patients were enrolled. Seventy-eight percent had pain prior to surgery, and for 38%, the pain had neuropathic characteristics. Thirteen patients (48%) completed at least 2 weeks of the postoperative pain diary. Patients with moderate/severe preoperative pain report significantly greater pain scores postoperatively, though daily pain decreased at a similar linear rate for all patients. Patients with more severe preoperative pain consumed greater amounts of opioids postoperatively, and this correlated with daily postoperative pain scores. Patients who screened positive for neuropathic pain also reported worse postoperative pain. Longitudinal perioperative pain assessment in head and neck patients undergoing surgery suggests that patients with worse preoperative pain continue to endorse worse pain postoperatively and require more narcotics. Patients with preoperative neuropathic pain also report poor pain control postoperatively, suggesting an opportunity to identify these patients and intervene with empiric neuropathic pain treatment.

Patient-reported outcome measures reveal the quality of surgical care from the patient's perspective. We aimed to compare body image, self-esteem, hospital anxiety and depression, and cosmetic outcomes by using validated tools between patients undergoing robot-assisted surgery and those undergoing conventional open surgery. This single-center, multidisciplinary, randomized, prospective study of 62 patients who underwent cardiac surgery was conducted at Hospital from May 2013 to January 2015. The patients were divided into two groups: the robotic group (n = 33) and the open group (n = 29). The study employed five different tools to assess body image, self-esteem, and overall patient-rated scar satisfaction. There were statistically significant differences between the groups in terms of self-esteem scores (p = 0.038), body image scores (p = 0.026), overall Observer Scar Assessment Scale (p = 0.013), and overall Patient Scar Assessment Scale (p = 0.036) scores in favor of the robotic group during the postoperative period. Robot-assisted surgery protected the patient's body image and self-esteem, while conventional open surgery decreased these levels but without causing pathologies. Preoperative depression and anxiety level was reduced by both robot-assisted surgery and conventional open surgery. The groups did not significantly differ on Patient Satisfaction Scores and depression/anxiety scores. The results of this study clearly demonstrated that a minimally invasive approach using robotic-assisted surgery has advantages in terms of body image, self-esteem, and cosmetic outcomes over the conventional approach in patients undergoing cardiac surgery.

The Canadian Cardiovascular Society Guidelines Committee and key Canadian opinion leaders believed there was a need for up to date guidelines that used the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system of evidence assessment for patients who undergo noncardiac surgery. Strong recommendations included: 1) measuring brain natriuretic peptide (BNP) or N-terminal fragment of proBNP (NT-proBNP) before surgery to enhance perioperative cardiac risk estimation in patients who are 65 years of age or older, are 45-64 years of age with significant cardiovascular disease, or have a Revised Cardiac Risk Index score ≥ 1; 2) against performing preoperative resting echocardiography, coronary computed tomography angiography, exercise or cardiopulmonary exercise testing, or pharmacological stress echocardiography or radionuclide imaging to enhance perioperative cardiac risk estimation; 3) against the initiation or continuation of acetylsalicylic acid for the prevention of perioperative cardiac events, except in patients with a recent coronary artery stent or who will undergo carotid endarterectomy; 4) against α 2 agonist or β-blocker initiation within 24 hours before surgery; 5) withholding angiotensin-converting enzyme inhibitor and angiotensin II receptor blocker starting 24 hours before surgery; 6) facilitating smoking cessation before surgery; 7) measuring daily troponin for 48 to 72 hours after surgery in patients with an elevated NT-proBNP/BNP measurement before surgery or if there is no NT-proBNP/BNP measurement before surgery, in those who have a Revised Cardiac Risk Index score ≥1, age 45-64 years with significant cardiovascular disease, or age 65 years or older; and 8) initiating of long-term acetylsalicylic acid and statin therapy in patients who suffer myocardial injury/infarction after surgery.

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.

To test the effects of the implementation of 3D laparoscopic technology for the execution of nerve-sparing radical hysterectomy. Thirty patients undergoing nerve-sparing radical hysterectomy via 3D laparoscopic (3D-LNSRH, n = 10) or open surgery (NSRH, n = 20) were studied prospectively. No significant differences were observed in baseline patient characteristics. Operative times were similar between groups. We compared the first 10 patients undergoing 3D-LNSRH with the last 20 patients undergoing NSRH. Baseline characteristics were similar between groups (p>0.2). Patients undergoing 3D-LNSRH had longer operative time (264.4 ± 21.5 vs 217.2 ± 41.0 minutes; p = 0.005), lower blood loss (53.4 ± 26.1 vs 177.7 ± 96.0 mL; p<0.001), and shorter length of hospital stay (4.3 ± 1.2 vs 5.4 ± 0.7 days; p = 0.03) in comparison to patients undergoing open abdominal procedures. No intraoperative complication occurred. One (10%) patient had conversion to open surgery due to technical difficulties and the inability to insert the uterine manipulator. A trend towards higher complication (grade 2 or worse) rate was observed for patients undergoing NSRH in comparison to 3D-LNSRH (p = 0.06). Considering only severe complications (grade 3 or worse), no difference was observed (0/10 vs 2/20; p = 0.54). 3D-laparoscopic nerve-sparing radical hysterectomy is a safe and effective procedure. The implementation of 3D laparoscopic technology allows the execution of challenging operations via minimally invasive surgery, thus reducing open abdominal procedure rates. Further large prospective studies are warranted.

Women undergoing minimally invasive robotic-assisted surgery for a gynecologic malignancy have many questions and concerns related to the cancer diagnosis and surgery. The provision of information enhances coping with such illness-related challenges. A lack of print materials for these patients prompted the creation of a written teaching tool to improve informational support. A booklet was developed using guidelines for the design of effective patient education materials, including an iterative process of collaboration with healthcare providers and women who had undergone robotic-assisted surgery, as well as attention to readability. The 52-page booklet covers the trajectory of the woman's experience and includes the physical, psychosocial, and sexual aspects of recovery.

Although there have been meta-analyses of the effects of exercise prehabilitation on patients undergoing colorectal surgery, little is known about the effects of nutrition-only (oral nutritional supplements and/or counseling) and multi-modal (oral nutritional supplements and/or counseling with exercise) prehabilitation on clinical outcomes and patient function after surgery. We performed a systemic review and meta-analysis to determine the individual and combined effects of nutrition-only and multi-modal prehabilitation, compared with no prehabilitation (control), on outcomes of patients undergoing colorectal resection. We searched MEDLINE, EMBASE, CINAHL, CENTRAL, and ProQuest for cohort and randomized controlled studies of adults awaiting colorectal surgery who received at least 7 days of oral nutrition supplements and/or nutrition counselling with or without exercise. We performed a random effects meta-analysis to estimate the pooled risk ratio for categorical data and the weighted mean difference for continuous variables. The primary outcome was length of hospital stay; the secondary outcome was recovery of functional capacity, based on results of a 6-minute walk test. We identified 9 studies (5 randomized controlled studies and 4 cohort studies) comprising 914 patients undergoing colorectal surgery (438 received prehabilitation and 476 served as controls). Receipt of any prehabilitation significantly reduced days spent in hospital compared with controls (weighted mean difference of length of hospital stay, -2.2 days; 95% CI, -3.5 days to -0.9 days). Only 3 studies reported functional outcomes but could not be pooled due to methodological heterogeneity. In the individual studies, multimodal prehabilitation significantly improved results of the 6-minute walk test at 4 and 8 weeks after surgery compared with standard enhanced recovery pathway care, and at 8 weeks compared with standard enhanced recovery pathway care with added rehabilitation. The 4 observational studies had a high risk of bias. In a systematic review and meta-analysis, we found that nutritional prehabilitation alone, or when combined with an exercise program, significantly reduced length of hospital stay by 2 days in patients undergoing colorectal surgery. There is some evidence that multimodal prehabilitation accelerated the return to pre-surgery functional capacity. Copyright © 2018 AGA Institute. Published by Elsevier Inc. All rights reserved.

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.

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.

Arthroscopic hip surgery has risen 18-fold in the past decade; however, there is a dearth of clinical trials comparing surgery with nonoperative management. To determine the comparative effectiveness of surgery and physical therapy for femoroacetabular impingement syndrome. Randomized controlled trial; Level of evidence, 1. Patients were recruited from a large military hospital after referral to the orthopaedic surgery clinic and were eligible for surgery. Of 104 eligible patients, 80 elected to participate, and the majority were active-duty service members (91.3%). No patients withdrew because of adverse events. The authors randomly selected patients to undergo either arthroscopic hip surgery (surgery group) or physical therapy (rehabilitation group). Patients in the rehabilitation group began a 12-session supervised clinic program within 3 weeks, and patients in the surgery group were scheduled for the next available surgery at a mean of 4 months after enrollment. Patient-reported outcomes of pain, disability, and perception of improvement over a 2-year period were collected. The primary outcome was the Hip Outcome Score (HOS; range, 0-100 [lower scores indicating greater disability]; 2 subscales: activities of daily living and sport). Secondary measures included the International Hip Outcome Tool (iHOT-33), Global Rating of Change (GRC), and return to work at 2 years. The primary analysis was on patients within their original randomization group. Statistically significant improvements were seen in both groups on the HOS and iHOT-33, but the mean difference was not significant between the groups at 2 years (HOS activities of daily living, 3.8 [95% CI, -6.0 to 13.6]; HOS sport, 1.8 [95% CI, -11.2 to 14.7]; iHOT-33, 6.3 [95% CI, -6.1 to 18.7]). The median GRC across all patients was that they "felt about the same" (GRC = 0). Two patients assigned to the surgery group did not undergo surgery, and 28 patients in the rehabilitation group ended up undergoing surgery. A sensitivity analysis of "actual surgery" to "no surgery" did not change the outcome. Twenty (33.3%) patients who underwent surgery and 4 (33.3%) who did not undergo surgery were medically separated from military service at 2 years. There was no significant difference between the groups at 2 years. Most patients perceived little to no change in status at 2 years, and one-third of military patients were not medically fit for duty at 2 years. Limitations include a single hospital, a single surgeon, and a high rate of crossover. Registration: NCT01993615 ( ClinicalTrials.gov identifier).

Severe blood loss is a common complication of craniofacial reconstruction surgery. The antifibrinolytic ε-aminocaproic acid (EACA) reduces transfusion requirements in children undergoing cardiac surgery and in older children undergoing spine surgery. Tranexamic acid (TXA), another antifibrinolytic with a similar mechanism of action, has been shown to reduce blood loss and transfusion requirements in children undergoing craniofacial surgery. However, TXA has been associated with an increase in post-operative seizures and is more expensive than EACA. There is currently little published data evaluating the efficacy of EACA in children undergoing craniofacial surgery. This is a retrospective study of prospectively collected data from our craniofacial perioperative registries for children under 6 years of age who underwent anterior or posterior cranial vault reconstruction. We compared calculated blood loss, blood donor exposures, and post-operative drain output between subjects who received EACA and those who did not. The registry queries returned data from 152 subjects. Eighty-six did not receive EACA and 66 received EACA. The EACA group had significantly lower calculated blood loss (82 ± 43 vs. 106 ± 63 ml/kg, P = 0.01), fewer intraoperative blood donor exposures (median 2, interquartile range 1-2 vs. median 2, interquartile range 1-3; P = 0.02) and lower surgical drain output in the first post-operative 24 h (28 ml/kg vs. 37 ml/kg, P = 0.001) than the non-EACA group. In this analysis of prospectively captured observational data, EACA administration was associated with less calculated blood loss, intraoperative blood donor exposures, and post-operative surgical drain output. © 2015 The Acta Anaesthesiologica Scandinavica Foundation.

We aimed to investigate whether fluid therapy with a goal of near-maximal stroke volume (SV) guided by oesophageal Doppler (ED) monitoring result in a better outcome than that with a goal of maintaining bodyweight (BW) and zero fluid balance in patients undergoing colorectal surgery. In a double-blinded clinical multicentre trial, 150 patients undergoing elective colorectal surgery were randomized to receive fluid therapy after either the goal of near-maximal SV guided by ED (Doppler, D group) or the goal of zero balance and normal BW (Zero balance, Z group). Stratification for laparoscopic and open surgery was performed. The postoperative fluid therapy was similar in the two groups. The primary endpoint was postoperative complications defined and divided into subgroups by protocol. Analysis was performed by intention-to-treat. The follow-up was 30 days. The trial had 85% power to show a difference between the groups. The number of patients undergoing laparoscopic or open surgery and the patient characteristics were similar between the groups. No significant differences between the groups were found for overall, major, minor, cardiopulmonary, or tissue-healing complications (P-values: 0.79; 0.62; 0.97; 0.48; and 0.48, respectively). One patient died in each group. No significant difference was found for the length of hospital stay [median (range) Z: 5.00 (1-61) vs D: 5.00 (2-41); P=0.206]. Goal-directed fluid therapy to near-maximal SV guided by ED adds no extra value to the fluid therapy using zero balance and normal BW in patients undergoing elective colorectal surgery.

Biliary lithiasis is not much frequent in paediatric patients. The manegement of cholelithiasis in patients undergoing laparoscopic cholecystectomy is still controversial. We propose the preoperatory echographic study of the biliary tree 24-48 h before surgery, as the first choice, instead of the intraoperatory cholangiography. We made a retrospective study of 42 patients undergoing laparoscopic cholecystectomy due to symptomatic biliary lithiasis during the last 15 years, with ages between 18 months and 17-years-old (mean age 9,6-years-old) and weight between 11 and 70 kg (mean weight 42 kg) at the moment of surgery. Six of them had haematological illnesses, 17 came to the hospital because of acute abdominal pain, 10 had been studied because of recurrent abdominal pain and 9 had casual diagnoses. Abdominal sonography was performed in all patients 24-48 hours before surgery. Four children were diagnosed of biliary duct lithiasis: two choledocolithiasis and two stones in the cystic duct. One of the cystic stones was extracted in the operating room and the rest resolved spontaneously. One patient presented dilatation of choledocal duct after surgery, without any stones' evidence. Also this patient resolved spontaneously. We had no complications. Biliary lithiasis is not frequent in children, even if it seems to be increasing. A few of these patients will suffer of choledocolithiasis. The intraoperatory exploration of the biliary tree during laparoscopic surgery is technically difficult due the small size of paediatric patients. Cholangiography is not always successful and can produce some important complications as pancreatitis. Preoperative sonography 24-48 hours before surgery is a safe and efficient method for the diagnosis and follow-up of paediatric patients with biliary lithiasis undergoing laparoscopic cholecystectomy. It is safe enough to be performed without intraoperatory cholangiography.

The objective of this study was to evaluate the effects of musical intervention on preoperative anxiety and vital signs in patients undergoing day surgery. Studies and systematic meta-analyses have shown inconclusive results of the efficacy of music in reducing preoperative anxiety. We designed a study to provide additional evidence for its use in preoperative nursing care. Randomised, controlled study. Patients (n = 183) aged 18-65 admitted to our outpatient surgery department were randomly assigned to either the experimental group (music delivered by earphones) or control group (no music) for 20 minutes before surgery. Anxiety, measured by the State-Trait Anxiety Inventory, and vital signs were measured before and after the experimental protocol. A total of 172 patients (60 men and 112 women) with a mean age of 40·90 (SD 11·80) completed the study. The largest number (35·7%) was undergoing elective plastic surgery and 76·7% of the total reported previous experience with surgery. Even though there was only a low-moderate level of anxiety at the beginning of the study, both groups showed reduced anxiety and improved vital signs compared with baseline values; however, the intervention group reported significantly lower anxiety [mean change: -5·83 (SD 0·75) vs. -1·72 (SD 0·65), p < 0·001] on the State-Trait Anxiety Inventory compared with the control group. Patients undergoing day surgery may benefit significantly from musical intervention to reduce preoperative anxiety and improve physiological parameters. Finding multimodal approaches to ease discomfort and anxiety from unfamiliar unit surroundings and perceived risks of morbidity (e.g. disfigurement and long-term sequelae) is necessary to reduce preoperative anxiety and subsequent physiological complications. This is especially true in the day surgery setting, where surgical admission times are often subject to change and patients may have to accommodate on short notice or too long a wait that may provoke anxiety. Our results provide additional evidence that musical intervention may be incorporated into routine nursing care for patients undergoing minor surgery. © 2011 Blackwell Publishing Ltd.

Rajyoga meditation is a form of mind body intervention that is promoted by the Brahma Kumaris World Spiritual University. This form of meditation can be easily performed without rituals or mantras and can be practiced anywhere at any time. The practice of Rajyoga meditation can have beneficial effects on modulating anxiety and cortisol level in patients undergoing major cardiac surgery. A prospective randomized control study was carried out in a single tertiary care center. One hundred and fifty patients undergoing elective coronary artery bypass surgery were enrolled in the study. The patients were randomized in two groups namely, Group 1 (Rajyoga group) and Group 2 (Control Group). Anxiety was measured on a visual analog scale 1-10 before the start of Rajyoga training or patient counseling (T1), on the morning of the day of surgery (T2), on the 2nd postoperative day (T3), and on the 5th postoperative day (T4). The serum cortisol level was measured in the morning of the day of surgery (T1), on the 2nd postoperative day (T2) and on the 5th postoperative day (T3), respectively. In the study, it was seen that the anxiety level of the patients before the surgery (T1) and on the day of surgery (T2) were comparable between the two groups. However on the 2nd postoperative day (T3), the patients who underwent Rajyoga training had lower anxiety level in comparison to the control group (3.12 ± 1.45 vs. 6.12 ± 0.14, P < 0.05) and on the 5th postoperative day (T4) it was seen that Rajyoga practice had resulted in significant decline in anxiety level (0.69 ± 1.1 vs. 5.6 ± 1.38, P < 0.05). The serum cortisol level was also favorably modulated by the practice of Rajyoga meditation. Mindbody intervention is found to effective in reducing the anxiety of the patients and modulating the cortisol level in patients undergoing wellknown stressful surgery like coronary artery bypass surgery.

Patients undergoing vascular surgery procedures constitute a 'high-risk' group. Fatal and disabling perioperative complications are common. Complications arise via multiple aetiological pathways. This mechanistic redundancy limits techniques to reduce complications that target individual mechanisms, for example, anti-platelet agents. Remote ischaemic preconditioning (RIPC) induces a protective phenotype in at-risk tissue, conferring protection against ischaemia-reperfusion injury regardless of the trigger. RIPC is induced by repeated periods of upper limb ischaemia-reperfusion produced using a blood pressure cuff. RIPC confers some protection against cardiac and renal injury during major vascular surgery in proof-of-concept trials. Similar trials suggest benefit during cardiac surgery. Several uncertainties remain in advance of a full-scale trial to evaluate clinical efficacy. We propose a feasibility trial to fully evaluate arm-induced RIPC's ability to confer protection in major vascular surgery, assess the incidence of a proposed composite primary efficacy endpoint and evaluate the intervention's acceptability to patients and staff. Four hundred major vascular surgery patients in five Irish vascular centres will be randomised (stratified for centre and procedure) to undergo RIPC or not immediately before surgery. RIPC will be induced using a blood pressure cuff with four cycles of 5 minutes of ischaemia followed by 5 minutes of reperfusion immediately before the start of operations. There is no sham intervention. Participants will undergo serum troponin measurements pre-operatively and 1, 2, and 3 days post-operatively. Participants will undergo 12-lead electrocardiograms pre-operatively and on the second post-operative day. Predefined complications within one year of surgery will be recorded. Patient and staff experiences will be explored using qualitative techniques. The primary outcome measure is the proportion of patients who develop elevated serum troponin levels in the first 3 days post-operatively. Secondary outcome measures include length of hospital and critical care stay, unplanned critical care admissions, death, myocardial infarction, stroke, mesenteric ischaemia and need for renal replacement therapy (within 30 days of surgery). RIPC is novel intervention with the potential to significantly improve perioperative outcomes. This trial will provide the first evaluation of RIPC's ability to reduce adverse clinical events following major vascular surgery. www.clinicaltrials.gov NCT02097186 Date Registered: 24 March 2014.

To develop and evaluate an individualized fluid therapy in the elderly patients with coronary heart disease undergoing gastrointestinal surgery. In this prospective study, 60 coronary heart disease patients undergoing gastrointestinal surgery were included in the First Affiliated Hospital of Xinjiang Medical University from March 2009 to March 2012. Patients were randomized into the intervention group and the control group with 30 patients in each group. Individualized fluid therapy was used during surgery and postoperative period in the ICU, which was determined based on target controlled fluid therapy according to cardiac index, stroke volume, and stroke volume variation. Traditional fluid therapy was used in the control group in the intraoperative and postoperative period. The two groups were compared in terms of postoperative hemodynamic parameters, total fluid volume, incidence of adverse cardiac events, and recovery of bowel function. Compared with the control group, mean arterial pressure was significantly increased at the commencement of the surgery. The cardiac index was significantly elevated during surgery and at the end of the surgery. Stroke volume was significantly increased after induction of anesthesia, during the surgery, and at the early stay of ICU period(all P<0.05). Serum lactic acid in the intervention group was significantly lower at the end of surgery and during ICU stay than that in the control group (all P<0.05). During surgery and 24-hour stay in ICU, the total fluid volume, crystal usage, and urine were significantly less, while colloidal fluid use was significantly more in the intervention group as compared to the control group(all P<0.05). The perioperative adverse cardiac event rate was 36.7%(11/30) in the intervention group, lower than 56.7%(17/30) in the control group, but the difference was no statistically significance(P>0.05). In the intervention group, defecation time, time to first flatus, resumption of liquid intake, length of ICU stay and hospital stay were significantly less compared with the control group(P<0.05). In the elderly patients with coronary arterial disease undergoing gastrointestinal surgery, individualized fluid therapy can effectively decrease adverse cardiac events, improve postoperative gastrointestinal function, and reduce length of hospital stay.

Deep infection remains a serious complication of orthopaedic surgery. Knowledge of infection rates and causative organisms is important to guide infection control measures. The aim of the present study was to determine infection rates and causative organisms in elective shoulder surgery. Cases complicated by infection were identified and prospectively recorded over a 2-year period. All patients undergoing elective shoulder surgery in the concurrent period at a single Specialist Upper Limb Unit in the UK were identified from the hospital electronic database. In total, 1574 elective shoulder cases were performed: 1359 arthroscopic (540 with implant insertion) and 215 open (197 with implant insertion). The overall infection rate in open surgery of 2.5% was significantly higher than arthroscopic implant cases at 0.7% ( p  < 0.005). The overall infection rate in implant arthroscopic surgery was significantly higher at 0.7% compared to 0% in non-implant related surgery. ( p  < 0.05). Patients undergoing open shoulder surgery have a significantly higher risk of infection compared to arthroscopic shoulder surgery. Arthroscopic surgery with implant insertion has a statistically significantly higher risk of developing deep infection compared to procedures with no implant insertion. We recommend prophylactic antibiotics in open shoulder surgery and arthroscopic shoulder surgery with implant insertion.

Relative to outpatient surgery in hospital settings, ambulatory surgery centers (ASCs) are more efficient and associated with a lower cost per case. However, these facilities may also spur higher overall procedure utilization and thus lead to greater overall health care costs. The authors used the State Ambulatory Surgery Database from the State of Florida to identify Medicare-aged patients undergoing 4 common ambulatory procedures in 2006, including knee arthroscopy, cystoscopy, cataract removal, and colonoscopy. Hospital service areas (HSAs) were characterized according to ASC market share, that is, the proportion of residents undergoing outpatient surgery in these facilities. The authors then examined relationships between ASC market share and rates of each procedure. Age-adjusted rates of ambulatory surgery ranged from 190.5 cases per 1000 to 320.8 cases per 1000 in HSAs with low and high ASC market shares, respectively (P < .01). For all 4 procedures, adjusted rates of procedures were significantly higher in HSAs with the highest ASC market share. The greatest difference, both in relative and absolute terms, was observed for patients undergoing cystoscopy. In areas of high ASC market share, the age-adjusted rate of cystoscopy was nearly 3-fold higher than in areas with low ASC market share (34.5 vs 11.9 per 1000 population; P < .01). The presence of an ASC is associated with higher utilization of common outpatient procedures in the elderly. Whether ASCs are meeting unmet clinical demand or spurring overutilization is not clear.

Preoperative exposure to clopidogrel and aspirin significantly increases postoperative bleeding in patients undergoing on-pump coronary artery bypass graft surgery. Off-pump coronary bypass grafting has been proposed as an alternative technique to attenuate postoperative bleeding associated with clopidogrel. This study aimed to determine the effects of aspirin and clopidogrel therapy on perioperative blood loss and blood transfusion requirements in off-pump coronary artery bypass grafting. One hundred six patients scheduled for off-pump coronary artery bypass grafting were divided into three groups: aspirin and clopidogrel discontinued more than 6 days before surgery (group 1, n = 35), aspirin and clopidogrel continued until 3 to 5 days before surgery (group 2, n = 51), and both medications continued within 2 days of surgery (group 3, n = 20). Thromboelastographic tracings were analyzed before induction of anesthesia. Routine coagulation profiles were measured before and after surgery. A cell salvage device was used during surgery and salvaged blood was reinfused. Chest tube drainage and blood transfusion requirement were recorded postoperatively. Patient characteristics, operative data, and thromboelastographic tracings were similar among the groups. There were significant decreases in hematocrit level and platelet count and prolongation in prothrombin time postoperatively in all groups without any intergroup differences. The amounts of perioperative blood loss and blood transfusion required were all similar among the groups. Preoperative clopidogrel and aspirin exposure even within 2 days of surgery does not increase perioperative blood loss and blood transfusion requirements in patients undergoing elective off-pump coronary artery bypass grafting.

To compare revision rates for ptosis surgery between posterior-approach and anterior-approach ptosis repair techniques. This is the retrospective, consecutive cohort study. All patients undergoing ptosis surgery at a high-volume oculofacial plastic surgery practice over a 4-year period. A retrospective chart review was conducted of all patients undergoing posterior-approach and anterior-approach ptosis surgery for all etiologies of ptosis between 2011 and 2014. Etiology of ptosis, concurrent oculofacial surgeries, revision, and complications were analyzed. The main outcome measure is the ptosis revision rate. A total of 1519 patients were included in this study. The mean age was 63 ± 15.4 years. A total of 1056 (70%) of patients were female, 1451 (95%) had involutional ptosis, and 1129 (74.3%) had concurrent upper blepharoplasty. Five hundred thirteen (33.8%) underwent posterior-approach ptosis repair, and 1006 (66.2%) underwent anterior-approach ptosis repair. The degree of ptosis was greater in the anterior-approach ptosis repair group. The overall revision rate for all patients was 8.7%. Of the posterior group, 6.8% required ptosis revision; of the anterior group, 9.5% required revision surgery. The main reason for ptosis revision surgery was undercorrection of one or both eyelids. Concurrent brow lifting was associated with a decreased, but not statistically significant, rate of revision surgery. Patients who underwent unilateral ptosis surgery had a 5.1% rate of Hering's phenomenon requiring ptosis repair in the contralateral eyelid. Multivariable logistic regression for predictive factors show that, when adjusted for gender and concurrent blepharoplasty, the revision rate in anterior-approach ptosis surgery is higher than posterior-approach ptosis surgery (odds ratio = 2.08; p = 0.002). The overall revision rate in patients undergoing ptosis repair via posterior-approach or anterior-approach techniques is 8.7%. There is a statistically higher rate of revision with anterior-approach ptosis repair.

The present study aimed to compare the utility of various inflammatory marker- and nutritional status-based prognostic factors, including many previous established prognostic factors, for predicting the prognosis of stage IV gastric cancer patients undergoing non-curative surgery. A total of 33 patients with stage IV gastric cancer who had undergone palliative gastrectomy and gastrojejunostomy were included in the study. Univariate and multivariate analyses were performed to evaluate the relationships between the mGPS, PNI, NLR, PLR, the CONUT, various clinicopathological factors and cancer-specific survival (CS). Among patients who received non-curative surgery, univariate analysis of CS identified the following significant risk factors: chemotherapy, mGPS and NLR, and multivariate analysis revealed that the mGPS was independently associated with CS. The mGPS was a more useful prognostic factor than the PNI, NLR, PLR and CONUT in patients undergoing non-curative surgery for stage IV gastric cancer.

To evaluate the prophylactic use of dexamethasone with sevoflurane in outpatient anorectal surgery. Randomized, controlled study. Operating room and Postanesthesia Care Unit of a general hospital. 60 adult, ASA physical status I and II outpatients undergoing anorectal surgery. Patients were randomized to receive either dexamethasone 5 mg intravenously (IV; Group D; n = 30) or an equal volume of saline (Group S; n = 30) before anesthesia induction. Anesthesia was induced with propofol 2.5 mg.kg(-1), fentanyl two microg.kg(-1), and 2% lidocaine one mg.kg(-1) followed by placement of a Laryngeal Mask Airway. Frequency of postoperative nausea and vomiting (PONV), visual analog scale (VAS) pain scores, and patient satisfaction were recorded. Frequency of PONV and VAS pain scores were significantly lower in Group D than Group S (P < 0.05). The time required for "home readiness" was significantly shorter in Group D than Group S (P < 0.05). The prophylactic administration of 5 mg dexamethasone IV can reduce the frequency of PONV, lower VAS pain scores, facilitate recovery to home readiness, and improve satisfaction in outpatients undergoing anorectal surgery.

Purpose To determine clinicodemographic factors associated with complications of continence procedures, the impact of concomitant surgeries on complication rates and the relationship between incidence of cystitis and method of post-operative bladder drainage. Materials and Methods Serious adverse events (SAEs) and adverse events (AEs) of the Stress Incontinence Surgical Efficacy Trial (SISTEr), a randomized trial comparing Burch colposuspension to autologous rectus fascial sling, were reviewed. Clinicodemographic variables were analyzed to determine those associated with the development of AEs using logistic regression analysis. Complications were stratified based on the presence or absence of concomitant surgery. Differences in complication rates (controlling for concomitant surgery) and cystitis rates (controlling for method of bladder emptying) were compared using Fisher’s exact test. Results Blood loss (p=0.0002) and operative time (p<0.0001) were significantly associated with development of an AE. Subjects undergoing concomitant surgeries had a significantly higher SAE rate (14.2% vs 7.3%, p=0.01) and AE rate (60.5% vs. 48%, p<0.01) compared to subjects undergoing continence surgery alone. Cystitis rates were higher (p<0.01) in the sling versus the Burch group up to 6 weeks postoperatively regardless of concomitant surgery status. Intermittent self catheterization (ISC) increased the rate of cystitis by 17% and 23% in the Burch and sling groups, respectively. Conclusions Concomitant surgeries at the time of continence surgery increased the risk for complications. Sling surgery was associated with a higher risk of cystitis within the first 6 weeks postoperatively. ISC increased risk of cystitis in both groups. The occurrence of complications was associated with surgical factors, not patient-related factors. PMID:19296969

The aim of the study was to evaluate selected blood coagulation and fibrinolysis parameters in patients undergoing total hip replacement surgery with normovolemic hemodilution and standard enoksaparine profilaxis. The study included 66 patients undergoing hip replacement surgery. The group consisted of 51 women and 15 men, within the age range of 47-78, the mean age was 64. In 32 (subgroup II) patients the surgery was performed with the use of normovolemic hemodilution, in 34 (subgroup I) the hemodilution procedure was not applied. The enoksaparine as prophylaxis started 12 hours prior to surgery and continued during hospitalisation. The examination of the coagulation system was performed: on the day of the operation in the morning, on the day of the operation in the evening and on the first day after operation. We determined the concentrations of TAT and PAP complexes, prothrombin fragments 1 + 2 (F1 + 2) and d-dimers (DD). 1) during total hip replacement surgery and particularly in the period of the first 12 hours after the procedure marked activation of coagulation and fibrinolysis occurRed; 2) the application of the hemodilution procedure does not influence significantly the degree of coagulation and fibrinolysis disorders in the perioperative period, but could reduced incidence of thromboembolic complications in the postoperative period.

Forty-six adult patients with cognitive impairment undergoing day-case dental surgery under general anesthesia were allocated to receive intraoperatively either fentanyl 50 μg iv bolus (group F, n = 23) or continuous infusion of remifentanil 0.5-1 μg/kg/min (group R, n = 23). Iintraoperative hemodynamic parameters were recorded and serum inflammatory mediators [tumor necrosis factor-α, substance-P], stress hormons (melatonin, cortisol) and β-endorphin were measured. Postoperative pain was assessed during the first postoperative 12 hours with the Wong-Baker faces pain-rating scale. Demographics were similar in two groups. The two groups did not differ regarding their effects on inflammatory mediators, stress hormons and postoperative pain scores. However, the use of remifentanil prevented intraoperative increases of arterial blood pressure and heart rate. Remifentanil and fentanyl did not affect differently stress and inflammatory hormones during day-case dental surgery, although remifentanil may render intraoperative management of hemodynamic responses easier. Both opioids are equally efficient for postoperative pain management following dental surgery in people with special needs.

Combined adenocarcinoid and mucinous cystadenoma of the appendix: a case report

PubMed Central

2009-01-01

Introduction Adenocarcinoid of the appendix is a rare malignant tumour with features of both adenocarcinoma and carcinoid, showing both epithelial and endocrine differentiation. Mucinous cystadenoma is the commonest of the benign neoplasms of the appendix, with an incidence of 0.6% in appendicectomy specimens. We report a rare combination of these tumours and discuss the latest treatment options. To the best of our knowledge, only six cases have been reported in the literature to date. Case presentation A 71-year-old Caucasian man presented to our department with a right iliac fossa mass associated with pain. Laparoscopy revealed an adenocarcinoid of the appendix in combination with mucinous cystadenoma. He underwent a radical right hemicolectomy with clear margins and lymph nodes. Conclusion Adenocarcinoids account for 2% of primary appendiceal malignancies. Most tumours are less than 2 cm in diameter and 20% of them metastasize to the ovaries. The mean age for presentation is 59 years and the 5-year survival rate ranges from 60% to 84%. Right hemicolectomy is generally advised if any of the following features are present: tumours greater than 2 cm, involvement of resection margins, greater than 2 mitoses/10 high-power fields on histology, extension of tumour beyond serosa. Chemotherapy mostly with 5-Fluorouracil and Leucovorin is advised for remnant disease after surgery. Cytoreductive surgery with intraperitoneal chemotherapy can offer improved survival for advanced peritoneal dissemination. PMID:19171048

Transpulmonary thermodilution allows the measurement of cardiac index for high risk surgical patients. Oncologic patients often have a central venous access (port-a-catheter) for chronic treatment. The validity of the measurement by a port-a-catheter of the absolute cardiac index and the detection of changes in cardiac index induced by fluid challenge are unknown. We conducted a monocentric prospective study. 27 patients were enrolled. 250 ml colloid volume expansions for fluid challenge were performed during ovarian cytoreductive surgery. The volume expansion-induced changes in cardiac index measured by transpulmonary thermodilution by a central venous access (CIcvc) and by a port-a-catheter (CIport) were recorded. 23 patients were analyzed with 123 pairs of measurements. Using a Bland and Altman for repeated measurements, the bias (lower and upper limits of agreement) between CIport and CIcvc was 0.14 (-0.59 to 0.88) L/min/m2. The percentage error was 22%. The concordance between the changes in CIport and CIcvc observed during volume expansion was 92% with an r = 0.7 (with exclusion zone). No complications (included sepsis) were observed during the follow up period. The transpulmonary thermodilution by a port-a-catheter is reliable for absolute values estimation of cardiac index and for measurement of the variation after fluid challenge. clinicaltrials.gov NCT02063009.

Laparoscopic surgery is well accepted as a safe technique when performed on a third trimester pregnant woman. The aim is to describe the anaesthetic management of a group of patients undergoing this type of surgery. An analysis was made of records of 6 patients in their third trimester of pregnancy and who underwent urgent laparoscopic surgery from 2011 to 2013. The study included 6 patients, with a diagnosis of acute cholecystitis in 4 of them. The other 2 patients had acute appendicitis, both of who presented threatened preterm labour. The most frequent indications for laparoscopic surgery during the last trimester of birth were found to be acute cholecystitis and acute appendicitis. Acute appendicitis is related to an elevated risk of presenting threatened preterm labour. Copyright © 2015 Academia Mexicana de Cirugía A.C. Publicado por Masson Doyma México S.A.

Retrospective database analysis. To evaluate outcomes of human immunodeficiency virus (HIV) positive patients after cervical spine surgery. Highly active antiretroviral medications have qualitatively altered the natural history of HIV, thus increasing the number of HIV-positive patients seeking treatment for chronic degenerative conditions. Minimal data exist on HIV patients undergoing degenerative cervical spine surgery. The Nationwide Inpatient Sample was examined from 2002 to 2011. Hospitalizations were identified using International Classification of Diseases Ninth Revision, Clinical Modification (ICD-9-CM) procedural codes for cervical spine surgery and diagnoses codes for degenerative conditions of the cervical spine, and HIV. Statistical analysis was conducted to evaluate associations between HIV status and perioperative complications. A total of 1,602,129 patients underwent degenerative cervical spine surgery, of which 3700 patients (0.23%) had HIV. The prevalence of HIV increased over the study period from 0.19% to 0.33% (P < 0.001). Patients with HIV were younger (48.6 yrs vs. 53.4 yrs, P < 0.001) and more likely to be male (P < 0.001). HIV patients had significantly greater odds of having chronic pulmonary disease, liver disease, and drug abuse. Unadjusted analysis did not reveal increased rate of acute complications among HIV-positive patients compared with negative controls (3.8% vs. 3.7%, P = 0.62). Multivariate analysis did not identify HIV as a significant predictor of complication (odds ratio = 1.04, P = 0.84). HIV was associated with a 1.5 day increased length of stay AND 1.29 fold increase in median costs compared with controls ($14,551 vs. 18,846, P < 0.001). The prevalence of HIV patients undergoing degenerative cervical spine surgery is increasing. A diagnosis of HIV was not associated with an increased risk of perioperative complication among patients undergoing degenerative cervical spine surgery. Further clinical studies are needed to evaluate predictors of complications among HIV patients and long-term outcomes. 4.

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.

Tranexamic acid reduces the risk of bleeding among patients undergoing cardiac surgery, but it is unclear whether this leads to improved outcomes. Furthermore, there are concerns that tranexamic acid may have prothrombotic and proconvulsant effects. In a trial with a 2-by-2 factorial design, we randomly assigned patients who were scheduled to undergo coronary-artery surgery and were at risk for perioperative complications to receive aspirin or placebo and tranexamic acid or placebo. The results of the tranexamic acid comparison are reported here. The primary outcome was a composite of death and thrombotic complications (nonfatal myocardial infarction, stroke, pulmonary embolism, renal failure, or bowel infarction) within 30 days after surgery. Of the 4662 patients who were enrolled and provided consent, 4631 underwent surgery and had available outcomes data; 2311 were assigned to the tranexamic acid group and 2320 to the placebo group. A primary outcome event occurred in 386 patients (16.7%) in the tranexamic acid group and in 420 patients (18.1%) in the placebo group (relative risk, 0.92; 95% confidence interval, 0.81 to 1.05; P=0.22). The total number of units of blood products that were transfused during hospitalization was 4331 in the tranexamic acid group and 7994 in the placebo group (P<0.001). Major hemorrhage or cardiac tamponade leading to reoperation occurred in 1.4% of the patients in the tranexamic acid group and in 2.8% of the patients in the placebo group (P=0.001), and seizures occurred in 0.7% and 0.1%, respectively (P=0.002 by Fisher's exact test). Among patients undergoing coronary-artery surgery, tranexamic acid was associated with a lower risk of bleeding than was placebo, without a higher risk of death or thrombotic complications within 30 days after surgery. Tranexamic acid was associated with a higher risk of postoperative seizures.

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.

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

To determine the frequency of dehiscence of hand-sutured and stapled intestinal anastomoses in the dog and compare the surgery duration for the methods of anastomosis. Historical cohort study. Two hundred fourteen client-owned dogs undergoing hand-sutured (n = 142) or stapled (n = 72) intestinal anastomoses. Medical records from 5 referral institutions were searched for dogs undergoing intestinal resection and anastomosis between March 2006 and February 2014. Demographic data, presence of septic peritonitis before surgery, surgical technique (hand-sutured or stapled), surgery duration, surgeon (resident versus faculty member), indication for surgical intervention, anatomic location of resection and anastomosis, and if dehiscence was noted postoperatively were retrieved. Estimated frequencies were summarized and presented as proportions and 95% confidence intervals (CI) and continuous outcomes as mean (95% CI). Comparisons were made across methods of anastomosis. Overall, 29/205 dogs (0.14, 95% CI 0.10-00.19) had dehiscence, including 21/134 dogs (0.16, 0.11-0.23) undergoing hand-sutured anastomosis and 8/71 dogs (0.11, 0.06-0.21) undergoing stapled anastomosis. There was no significant difference in the frequency of dehiscence across anastomosis methods (χ(2), P = .389). The mean (95% CI) surgery duration of 140 minutes (132-147) for hand- sutured anastomoses and 108 minutes (99-119) for stapled anastomoses was significantly different (t-test, P < .001). No significant difference in frequency of dehiscence was noted between hand- sutured and stapled anastomoses in dogs but surgery duration is significantly reduced by the use of staples for intestinal closure. © Copyright 2015 by The American College of Veterinary Surgeons.

It is well known that liver disease has an adverse effect on postoperative outcomes. However, what is still unknown is how to appropriately risk stratify this patient population based on the degree of liver failure. Because data are limited, specifically in general surgery practice, we analyzed the model of end-stage liver disease (MELD) in terms of predicting postoperative complications after one of three general surgery operations: inguinal hernia repair (IHR), umbilical hernia repair (UHR), and colon resection (CRXN). National Surgical Quality Improvement Program data on 17,812 total patients undergoing one of three general surgery operations from 2008 to 2012 were analyzed retrospectively. There were 7402 patients undergoing IHR; 5014 patients undergoing UHR; 5396 patients undergoing CRXN. MELD score was calculated using international normalized ratio, total bilirubin, and creatinine. The primary end point was any postoperative complication. The statistical method used was logistic regression. For IHR, UHR, and CRXN, the overall complication rates were 3.4, 6.4, and 45.9 per cent, respectively. The mean MELD scores were 8.6, 8.5, and 8.5, respectively. For every 1-point increase greater than the mean MELD score, there was a 7.8, 13.8, and 11.6 per cent increase in any postoperative complication. The overall 30-day mortality rate was 0.9 per cent. In conclusion, the MELD score continuum adequately predicts patients' increased risk of postoperative complications after IHR, UHR, and CRXN. Therefore, MELD could be used for preoperative risk stratification and guide clinical decision making for general surgery in the cirrhotic patient.

We performed a systematic review and meta-analysis to determine whether perioperative depression and anxiety are associated with increased postoperative mortality in patients undergoing cardiac surgery. MEDLINE and EMBASE were searched through January 2017 using PubMed and OVID, to identify observational studies enrolling patients undergoing cardiac surgery and reporting relative risk estimates (RREs) (including odds, hazard, or mortality ratios) of short term (30 days or in-hospital) and/or late all-cause mortality for patients with versus without perioperative depression or anxiety. Study-specific estimates were combined using inverse variance-weighted averages of logarithmic RREs in the random-effects models. Our search identified 16 eligible studies. In total, the present meta-analysis included data on 236,595 patients undergoing cardiac surgery. Pooled analysis demonstrated that perioperative depression was significantly associated with increased both postoperative early (RRE, 1.44; 95% confidence interval [CI] 1.01-2.05; p = 0.05) and late mortality (RRE, 1.44; 95% CI 1.24-1.67; p < 0.0001), and that perioperative anxiety significantly correlated with increased postoperative late mortality (RRE, 1.81; 95% CI 1.20-2.72; p = 0.004). The relation between anxiety and early mortality was reported in only one study and not statistically significant. In the association of depression with late mortality, there was no evidence of significant publication bias and meta-regression indicated that the effects of depression are not modulated by the duration of follow-up. In conclusion, perioperative depression and anxiety may be associated with increased postoperative mortality in patients undergoing cardiac surgery.

We evaluated the incidence of perioperative stroke following the institution's 2007 practice change of discontinuing combined carotid endarterectomy and open heart surgery (OHS) for patients with severe carotid stenosis. In this retrospective cohort study, we compared 113 patients undergoing coronary artery bypass grafting, aortic valve replacement, or both from 2007 to 2011 with data collected from 2001 to 2006 from a similar group of patients. Our aim was to assess whether the practice change led to a greater incidence of stroke. A total of 7350 consecutive patients undergoing OHS during the specified time period were screened. Of these, 3030 had OHS between 2007 and 2011 but none were combined with carotid artery surgery (new cohort). The remaining 4320 had OHS before 2007 and 44 had combined procedures (old cohort). Of patients undergoing OHS during the 10-year period of observation, 230 had severe (>80%) carotid stenosis. In the old cohort (before 2007), carotid stenosis was associated with perioperative stroke in 2.5% of cases. None of the 113 patients having cardiac procedures after 2007 received combined carotid artery surgery; only 1 of these patients harboring severe carotid stenosis had an ischemic stroke (.9%) during the perioperative period. The difference in stroke incidence between the 2 cohorts was statistically significant (P = .002). The incidence of stroke in patients with severe carotid artery stenosis undergoing OHS was lower after combined surgery was discontinued. Combined carotid and OHS itself seems to be an important risk factor for stroke. Copyright © 2017 National Stroke Association. Published by Elsevier Inc. All rights reserved.

Interatrial block (IAB) is a well-known entity that is associated with an increased risk of atrial fibrillation (AF). This association is called Bayes' syndrome. The aim of our study was to define the prevalence of IAB among patients younger than 65 years undergoing cardiac surgery and determine whether there is an association between the presence of interatrial conduction delay and postoperative atrial fibrillation (POAF). A total of 207 patients were enrolled. Partial IAB was defined as P-wave>120ms. Advanced IAB was defined as P-wave>120ms+biphasic morphology in the inferior leads. Ocurrence of POAF was assessed and a comparative analysis was conducted between patients that did and did not develop AF. IAB prevalence was 78.3% (partial 66.2%, advanced 12.1%). POAF occurred in 28.5% of all patients, and was more frequent among patients with advanced IAB (44%) compared to 27.7% and 24.4% of POAF among patients with partial IAB and without IAB, respectively. Patients who developed POAF were significantly older, had significantly higher NTproBNP, higher prevalence of atrial enlargement and thyroid disease. After multivariate analysis, advanced IAB was found to be independently associated with POAF. IAB is a frequent finding among patients undergoing cardiac surgery. According to our results, advanced IAB is independently associated with POAF in younger patients (<65 years) undergoing cardiac surgery.

Undergoing surgery is an anxious experience for children. Applying anxiety reduction age-appropriate programs by nurses would be beneficial in reducing anxiety to children. To test the effectiveness of age-appropriate preoperative information session in reducing anxiety levels of school-age children undergoing elective surgery in Jordan. The study used a quasi-experimental design. One hundred and twenty-six children were recruited from an educational hospital in Amman from January to June 2012 and were randomly assigned to intervention and control groups. The anxiety levels of children were assessed using the State Anxiety Scale for children, and children's levels of cooperation after surgery were assessed using Children Emotional Manifestation Scale. The heart rate and blood pressure of children were also measured 1 hour before going to operation room. The study results revealed that children in the intervention group reported lower anxiety levels and more cooperation than children in the control group. Also, they displayed lower heart rate and blood pressure than children in the control group. The application of age-appropriate preoperative intervention for children could be beneficial in decreasing anxiety levels and increasing their cooperation post surgery. © 2018 John Wiley & Sons Australia, Ltd.

Intraoperative hypothermia is common in patients undergoing general anesthesia during arthroscopic hip surgery. In the present study, we assessed the effect of heating and humidifying the airway with a heated wire humidification circuit (HHC) to attenuate the decrease of core temperature and prevent hypothermia in patients undergoing arthroscopic hip surgery under general anesthesia. Fifty-six patients scheduled for arthroscopic hip surgery were randomly assigned to either a control group using a breathing circuit connected with a heat and moisture exchanger (HME) (n = 28) or an HHC group using a heated wire humidification circuit (n = 28). The decrease in core temperature was measured from anesthetic induction and every 15 minutes thereafter using an esophageal stethoscope. Decrease in core temperature from anesthetic induction to 120 minutes after induction was lower in the HHC group (-0.60 ± 0.27℃) compared to the control group (-0.86 ± 0.29℃) (P = 0.001). However, there was no statistically significant difference in the incidence of intraoperative hypothermia or the incidence of shivering in the postanesthetic care unit. The use of HHC may be considered as a method to attenuate intraoperative decrease in core temperature during arthroscopic hip surgery performed under general anesthesia and exceeding 2 hours in duration.

To describe the clinical course of paediatric patients undergoing surgery for congenital heart disease in UMAE of Yucatan. Descriptive review was performed on the records of paediatric patients undergoing surgery for congenital heart disease from 1 November 2011 to 30 November 2013. The most frequent heart diseases were persistent ductus arteriosus (37.6%) and transposition of the great vessels. The median intensive care stay was 3 days. Mortality was 11.76%, with septic shock (44.4%) in most cases. The most frequent complications were sepsis (5.9%), low cardiac output syndrome (4.7%), cardiac arrest, and AV block and ventricular tachycardia (2.4% each). There was a moderate positive correlation between surgical complications and survival or death. The number of surgical patients is lower compared to reference centres for cardiovascular surgery. There is a marked tendency to perform corrective and palliative surgeries in specific disease in patients with added risk or 'bad' cardiac anatomy that prevent full correction at the first attempt. Prospective epidemiological and clinical studies should be conducted to understand the behaviour of congenital heart diseases treated in the region.

The authors determined the pharmacokinetics of fentanyl 100 micrograms X kg-1 iv in patients undergoing elective abdominal aortic surgery. The mean (+/- SD) age of the ten patients was 67.2 +/- 8.7 yr; their mean weight was 78.5 +/- 13.7 kg. Seven patients had aortic aneurysm repair, and the other three patients had aortobifemoral grafts. Serum fentanyl concentrations were determined from samples drawn at increasing intervals over a 24-h period. A three-compartment pharmacokinetic model was fit to the concentration versus time data. Total drug clearance was 9.8 +/- 1.8 ml X min-1 X kg-1. The volume of distribution at steady-state (Vdss) was 5.4 +/- 1.9 X 1 kg-1. Elimination half-time was 8.7 +/- 2.5 h. There were no significant correlations between these pharmacokinetic parameters and patient's age, duration of aortic cross-clamping, duration of surgery, intraoperative blood loss, or volume of iv fluids given intraoperatively. In healthy volunteers or patients undergoing general surgery, other investigators report mean elimination half-times for fentanyl ranging from 1.7 to 4.4 h. The prolonged elimination half-time in patients having abdominal aortic surgery has important clinical implications. In particular, recovery from large doses will take much longer than would have been anticipated from previously published fentanyl pharmacokinetic data.

This study investigated the effects of dexmedetomidine on heart-type fatty acid binding protein (H-FABP), creatine kinase isoenzymes (CK-MB), and troponin I (cTnI) levels, neurological function and near-term prognosis in patients undergoing heart valve replacement. Patients undergoing heart valve replacement were randomly allocated to remifentanil anesthesia (control group, n=48) or dexmedetomidine anesthesia (observation group, n=48). Hemodynamic parameters were measured before anesthesia induction (T1), 1 min after intubation (T2), 10 min after start of surgery (T3), and on completion of surgery (T4). Levels of plasma H-FABP, CK-MB and cTnI were measured 10 min before anesthesia induction (C1), 10 min after start of surgery (C2), on completion of surgery (C3), 6 h after surgery (C4), and 24 h after surgery (C5). S100β protein and serum neuron-specific enolase (NSE) were detected 10 min before anesthesia induction (C1), and 24 h after surgery (C5). Neurological and cardiac function was evaluated 24 h after surgery. Incidence of cardiovascular adverse events was recorded for 1 year of follow-up. There were no significant differences in the average heart rate between the two groups during the perioperative period. The mean arterial pressure in the observation group was significantly lower than control group (P<0.05). Levels of H-FABP, CK-MB and cTnI at C2, C3, C4 and C5, were significantly higher than C1, but significantly lower in the observation versus control group (P<0.05). Twenty-four hours after surgery, levels of S100β and NSE in both groups were higher than those before induction (P<0.05), but significantly lower in the observation versus control group (P<0.05). Twenty-four hours after surgery, neurological function scores were better, and myocardial contractility and arrhythmia scores significantly lower in the observation versus control group (P<0.05 for all). After follow-up for 1 year, incidence of cardiovascular adverse events was significantly lower in the observation versus control group (P<0.05). Dexmedetomidine anesthesia can effectively maintain hemodynamic stability, reduce myocardial injury and the occurrence of cognitive dysfunction, and improve prognosis in patients undergoing heart valve replacement.

To evaluate the main factors associated with mortality in patients undergoing surgery for perforated peptic ulcer referred to an academic department of general surgery in a large southern Italian city. One hundred and forty-nine consecutive patients (M:F ratio=110:39, mean age 52 yrs, range 16-95) with peptic ulcer disease were investigated for clinical history (including age, sex, previous history of peptic ulcer, associated diseases, delayed abdominal surgery, ulcer site, operation type, shock on admission, postoperative general complications, and intra-abdominal and/or wound infections), serum analyses and radiological findings. The overall mortality rate was 4.0%. Among all factors, an age above 65 years, one or more associated diseases, delayed abdominal surgery, shock on admission, postoperative abdominal complications and/or wound infections, were significantly associated (chi2) with increased mortality in patients undergoing surgery (0.0001

Patient anxiety about nail surgery relates mainly to pain associated with needle puncture, anesthetic flow during the procedure, and postoperative care, as well as possible past traumatic experience. The aims of this study were to compare anxiety levels among patients undergoing nail surgery and skin punch biopsy and to assess the effects of demographic characteristics on anxiety. Forty-eight consecutive patients who were referred to a dermatological surgery unit for nail surgery intervention (group 1) and 50 age- and sex-matched patients referred to the same unit for skin punch biopsy (group 2) were enrolled in the study. Patients' anxiety levels were measured using Spielberger's State-Trait Anxiety Inventory. There was no significant difference in median anxiety level between group 1 (42.00; interquartile range, 6.50) and group 2 (41.00; interquartile range, 8.25) (P = .517). The demographic factors of patient sex, educational status, and prior surgery showed no significant effects on anxiety levels. Nail surgery does not seem to cause significantly greater anxiety than skin punch biopsy. © The Author(s) 2015.

To assess and compare the efficacy and safety of topical versus peribulbar anaesthesia in patients undergoing routine cataract surgery. The unicentre, prospective, randomized, clinical interventional trial included 140 consecutive patients undergoing routine cataract surgery performed by one of two surgeons. The patients were randomly distributed to either peribulbar anaesthesia or topical anaesthesia. To assess intraoperative pain, each patient was asked immediately after surgery to quantitate his/her pain using a 10-point pain rating scale. The study groups did not differ significantly in pain score (p=0.54), duration of surgery (p=0.52), anaesthesia-related intraoperative difficulties (p=0.17), postoperative visual acuity (p=0.94), overall intraoperative surgical complication rate, blood pressure rise (p=0.16) or blood oxygen saturation (p=0.74) Patient comfort and surgery-related complications did not differ between topical anaesthesia and peribulbar anaesthesia. As there are no significant differences between the two techniques in terms of subjective pain experienced by patients, intraoperative complications and postoperative visual outcome, and in view of the minimally invasive character of topical anaesthesia compared to peribulbar anaesthesia, the present study suggests the use of topical anaesthesia for routine cataract surgery.

Determinants of demand for total hip and knee arthroplasty: a systematic literature review

PubMed Central

2012-01-01

Background Documented age, gender, race and socio-economic disparities in total joint arthroplasty (TJA), suggest that those who need the surgery may not receive it, and present a challenge to explain the causes of unmet need. It is not clear whether doctors limit treatment opportunities to patients, nor is it known the effect that patient beliefs and expectations about the operation, including their paid work status and retirement plans, have on the decision to undergo TJA. Identifying socio-economic and other determinants of demand would inform the design of effective and efficient health policy. This review was conducted to identify the factors that lead patients in need to undergo TJA. Methods An electronic search of the Embase and Medline (Ovid) bibliographic databases conducted in September 2011 identified studies in the English language that reported on factors driving patients in need of hip or knee replacement to undergo surgery. The review included reports of elective surgery rates in eligible patients or, controlling for disease severity, in general subjects, and stated clinical experts’ and patients’ opinions on suitability for or willingness to undergo TJA. Quantitative and qualitative studies were reviewed, but quantitative studies involving fewer than 20 subjects were excluded. The quality of individual studies was assessed on the basis of study design (i.e., prospective versus retrospective), reporting of attrition, adjustment for and report of confounding effects, and reported measures of need (self-reported versus doctor-assessed). Reported estimates of effect on the probability of surgery from analyses adjusting for confounders were summarised in narrative form and synthesised in odds ratio (OR) forest plots for individual determinants. Results The review included 26 quantitative studies−23 on individuals’ decisions or views on having the operation and three about health professionals’ opinions-and 10 qualitative studies. Ethnic and racial disparities in TJA use are associated with socio-economic access factors and expectations about the process and outcomes of surgery. In the United States, health insurance coverage affects demand, including that from the Medicare population, for whom having supplemental Medicaid coverage increases the likelihood of undergoing TJA. Patients with post-secondary education are more likely to demand hip or knee surgery than those without it (range of OR 0.87-2.38). Women are as willing to undergo surgery as men, but they are less likely to be offered surgery by specialists than men with the same need. There is considerable variation in patient demand with age, with distinct patterns for hip and knee. Paid employment appears to increase the chances of undergoing surgery, but no study was found that investigated the relationship between retirement plans and demand for TJA. There is evidence of substantial geographical variation in access to joint replacement within the territory covered by a public national health system, which is unlikely to be explained by differences in preference or unmeasured need alone. The literature tends to focus on associations, rather than testing of causal relationships, and is insufficient to assess the relative importance of determinants. Conclusions Patients’ use of hip and knee replacement is a function of their socio-economic circumstances, which reinforce disparities by gender and race originating in the doctor-patient interaction. Willingness to undergo surgery declines steeply after the age of retirement, at the time some eligible patients may lower their expectations of health status achievement. There is some evidence that paid employment independently increases the likelihood of operation. The relative contribution of variations in surgical decision making to differential access across regions within countries deserves further research that controls for clinical need and patient lifestyle preferences, including retirement decisions. Evidence on this question will become increasingly relevant for service planning and policy design in societies with ageing populations. PMID:22846144

What is the current management of women with ovarian endometriomas undergoing assisted reproductive treatment (ART) in the UK? It appears that the majority of gynaecologists in the UK offer surgery (mostly cystectomy) for endometriomas prior to ART, regardless of the presence of symptoms. The ideal management of endometriomas in women undergoing ART remains controversial and presents a dilemma to reproductive specialists. This was a national cross-sectional survey. A total of 388 gynaecologists completed the questionnaire. All clinicians fully registered with the Royal College of Obstetricians and Gynaecologists were contacted. An 11-item survey was administered electronically using Survey Monkey software. Quantitative data were analysed using descriptive and comparative statistics. The majority of responders were consultants (65%), 25% practiced ART and 65% performed laparoscopic surgery. Overall, 95% of responders would offer surgery for endometriomas in women undergoing ART, either on the basis of the size (>3-5 cm) of the endometrioma (52%), the presence of symptoms (16%), the presence of multiple/bilateral endometriomas (2%), regardless of the size and symptoms (19%) or only to women undergoing IVF (6%). The remaining 5% of responders would not offer surgery before ART. Excision was the most common surgical modality (68%), followed by ablation (25%). Laparoscopic surgeons were almost twice as likely to 'offer surgery to all patients with endometriomas prior to ART' compared with clinicians performing laparotomy (22 versus 12%, P < 0.001). Our overall response rate, with answers to the questionnaire, was low (15%). However, the response rate amongst reproductive specialists was estimated at 60%. It is possible that there might have been an element of bias towards over-representation of responders who are more concerned about 'normalization' of the pelvic anatomy. Furthermore, our survey relied on self-reporting of practice and it is possible that being presented with a list of 'ideal' options may have resulted in respondent bias. Despite the available evidence that surgery for endometriomas does not improve the outcome of ART and may damage ovarian reserve, it seems that the majority of gynaecologists in the UK offer ovarian cystectomy to their patients.

Outcomes of robotic versus laparoscopic surgery for mid and low rectal cancer after neoadjuvant chemoradiation therapy and the effect of learning curve

Abstract Randomized controlled trials have demonstrated that laparoscopic surgery for rectal cancer is safe and can accelerate recovery without compromising oncological outcomes. However, such a surgery is technically demanding, limiting its application in nonspecialized centers. The operational features of a robotic system may facilitate overcoming this limitation. Studies have reported the potential advantages of robotic surgery. However, only a few of them have featured the application of this surgery in patients with advanced rectal cancer undergoing neoadjuvant chemoradiation therapy (nCRT). From January 2012 to April 2015, after undergoing nCRT, 40 patients with mid or low rectal cancer were operated using the robotic approach at our institution. Another 38 patients who were operated using the conventional laparoscopic approach were matched to patients in the robotic group by sex, age, the body mass index, and procedure. All operations were performed by a single surgical team. The clinicopathological characteristics and short-term outcomes of these patients were compared. To assess the effect of the learning curve on the outcomes, patients in the robotic group were further subdivided into 2 groups according to the sequential order of their procedures, with an equal number of patients in each group. Their outcome measures were compared. The robotic and laparoscopic groups were comparable with regard to pretreatment characteristics, rectal resection type, and pathological examination result. After undergoing nCRT, more patients in the robotic group exhibited clinically advanced diseases. The complication rate was similar between the 2 groups. The operation time and the time to the resumption of a soft diet were significantly prolonged in the robotic group. Further analysis revealed that the difference was mainly observed in the first robotic group. No significant difference was observed between the second robotic and laparoscopic groups. Although the robotic approach may offer potential advantages for rectal surgery, comparable short-term outcomes may be achieved when laparoscopic surgery is performed by experienced surgeons. However, our results suggested a shorter learning curve for robotic surgery for rectal cancer, even in patients who exhibited more advanced disease after undergoing nCRT. PMID:28984767

Postoperative acute kidney injury (AKI) is a frequent and serious complication after cardiac surgery. Clinical factors alone have failed to accurately predict the incidence of AKI after cardiac surgery. Ethnicity has been shown to be a predictor of AKI in the Western population. We tested the hypothesis that ethnicity is an independent predictor of AKI in patients undergoing cardiac surgery in a South East Asian population. A total of 1756 consecutive patients undergoing cardiac surgery were prospectively recruited. Among them, data of 1639 patients met the criteria for analysis. There were 1182 Chinese, 195 Indian, and 262 Malay patients. The main outcome was postoperative AKI, defined as a 25% or greater increase in preoperative to a maximum postoperative serum creatinine level within 3 days after surgery. Five hundred and seventy-nine patients (35.3%) developed AKI after cardiac surgery. Ethnicity was shown to be an independent predictor of AKI after cardiac surgery with Indians and Malays having a higher risk of developing AKI when compared with Chinese patients (odds ratio: Indian vs Chinese 1.44, Malay vs Chinese 1.51). Indians and Malays have a higher risk of developing AKI after cardiac surgery than Chinese in a South East Asian population. Ethnicity was shown to be an independent predictor of AKI after cardiac surgery.

OBJECTIVE Geriatric patients undergoing lumbar spine surgery have unique needs due to the physiological changes of aging. They are at risk for adverse outcomes such as delirium, infection, and iatrogenic complications, and these complications, in turn, contribute to the risk of functional decline, nursing home admission, and death. Whether preoperative and perioperative comanagement by a geriatrician reduces the incidence of in-hospital complications and length of in-hospital stay after elective lumbar spine surgery remains unknown. METHODS A unique model of comanagement for elderly patients undergoing lumbar fusion surgery was implemented at a major academic medical center. The Perioperative Optimization of Senior Health (POSH) program was launched with the aim of improving outcomes in elderly patients (> 65 years old) undergoing complex lumbar spine surgery. In this model, a geriatrician evaluates elderly patients preoperatively, in addition to performing routine preoperative anesthesia surgical screening, and comanages them daily throughout the course of their hospital stay to manage medical comorbid conditions and coordinate multidisciplinary rehabilitation along with the neurosurgical team. The first 100 cases were retrospectively reviewed after initiation of the POSH protocol and compared with the immediately preceding 25 cases to assess the incidence of perioperative complications and clinical outcomes. RESULTS One hundred twenty-five patients undergoing lumbar decompression and fusion were enrolled in this pilot program. Baseline characteristics were similar between both cohorts. The mean length of in-hospital stay was 30% shorter in the POSH cohort (6.13 vs 8.72 days; p = 0.06). The mean duration of time between surgery and patient mobilization was significantly shorter in the POSH cohort compared with the non-POSH cohort (1.57 days vs 2.77 days; p = 0.02), and the number of steps ambulated on day of discharge was 2-fold higher in the POSH cohort (p = 0.04). Compared with the non-POSH cohort, the majority of patients in the POSH cohort were discharged to home (24% vs 54%; p = 0.01). CONCLUSIONS Geriatric comanagement reduces the incidence of postoperative complications, shortens the duration of in-hospital stay, and contributes to improved perioperative functional status in elderly patients undergoing elective spinal surgery for the correction of adult degenerative scoliosis.

There is a paucity of literature describing the association of age with the risk of adverse events following bariatric surgery. The purpose of this study is to investigate the association of age with 30-day morbidity and mortality following laparoscopic bariatric surgery using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database. All adult patients undergoing laparoscopic Roux-en-Y gastric bypass (RNGYB) or sleeve gastrectomy (SG) were identified within the MBSAQIP database. Patients were divided into five equal age quintiles. Binary outcomes of interest, including cardiac, pulmonary, wound, septic, clotting, and renal events, in addition to the incidence of related 30-day unplanned reintervention, related 30-day mortality, and a composite morbidity and mortality outcome were compared across the age quintiles and procedures. A total of 266,544 patients met inclusion criteria. Older age was associated with an increased risk of all morbidity outcomes except venous thromboembolism events, 30-day mortality, and the composite morbidity and mortality outcome. Patients who underwent Roux-en-Y gastric bypass had worse outcomes per quintile for almost every outcome of interest when compared to patients who underwent sleeve gastrectomy. Older patients and patients who undergo Roux-en-Y gastric bypass are at an increased risk of perioperative morbidity and mortality following laparoscopic bariatric surgery. Additional studies are needed to determine the association of age with long-term weight loss and cardiometabolic comorbidity resolution following bariatric surgery in order to determine if the increased perioperative risk is offset by improved long-term outcomes in older patients undergoing bariatric surgery.

The aim of this study is to determine whether preoperative scores on a screening measure for cognitive status (the Saint Louis University mental status examination), were associated with discharge to a location other than home in older patients undergoing surgery for deformity. Older patients (≥65 years) undergoing a planned elective spinal surgery for correction of adult degenerative scoliosis were enrolled in this study. Preoperative baseline cognition was assessed using the validated Saint Louis University mental status (SLUMS) test. SLUMS is 11 questions with a maximum of 30 points. Mild cognitive impairment was defined as a SLUMS score of 21-26 points, and severe cognitive impairment as a SLUMS score of 20 points or greater. Normal cognition was defined as a SLUMS score of 27 points or more. Postoperative length of stay and discharge location were recorded on all patients. Eighty-two subjects were included, with mean ± standard deviation age of 73.26 ± 6.08 years; 51% of patients were discharged to a facility (skilled nursing or acute rehabilitation). After adjustment for demographic variables, comorbidities, and baseline cognitive impairment, patients with preoperative cognitive impairment were 4-fold more likely to be discharged to a facility (skilled nursing or acute rehabilitation) compared with patients with normal cognitive status (odds ratio [OR], 3.93). In addition, patients who were not ambulatory before surgery were also more likely to be discharged to a facility (OR, 7.14). In geriatric patients undergoing surgery for deformity correction, cognitive screening before surgery can identify patients with impaired cognitive status who are less likely than those with normal cognitive status to return home after surgery.

Background and purpose - Detailed information on the symptoms and limitations that patients with meniscal tears experience is lacking. This study was undertaken to map the most prevalent self-reported symptoms and functional limitations among patients undergoing arthroscopic meniscal surgery and investigate which symptoms and limitations had improved most at 1 year after surgery. Patients and methods - Patients aged 18-76 years from the Knee Arthroscopy Cohort Southern Denmark (KACS) undergoing arthroscopic meniscal surgery were included in this analysis of individual subscale items from the Knee Injury and Osteoarthritis Outcome Score and 1 question on knee stability. Severity of each item was scored as none, mild, moderate, severe, or extreme. Improvements were evaluated using Wilcoxon's signed-rank test and effect size (ES). Results - The most common symptoms were knee grinding and clicking, knee pain in general, pain when twisting and bending the knee and climbing stairs (88-98%), while the most common functional limitations were difficulty bending to the floor, squatting, twisting, kneeling, and knee awareness (97-99%). Knee pain in general and knee awareness improved most 1 year after meniscal surgery (ES -0.47 and -0.45; p < 0.001), while knee instability and general knee difficulties improved least (ES 0.10 and -0.08; p < 0.006). Interpretation - Adults undergoing surgery for a meniscal tear commonly report clinical symptoms and functional limitations related to their daily activities. Moderate improvements were observed in some symptoms and functional limitations and small to no improvement in others at 1 year after surgery. These findings can assist the clinical discussion of symptoms, treatments, and patients' expectations.

To evaluate the effects of repetition of the 6-minute walk test in patients scheduled to undergo abdominal surgery within the next 48 hours, and to verify the physical capacity of these subjects before surgery. Cross-sectional study. University teaching hospital. Forty-two patients scheduled for elective abdominal surgery within the next 48 hours. Distance walked in the 6-minute walk test, heart rate, peripheral oxygen saturation, dyspnoea and leg fatigue. Thirty-one patients (74%) were able to walk for a longer distance when the test was repeated. In these subjects, the mean increase in distance walked was 35.4 [standard deviation (SD) 19.9]m. Heart rate, dyspnoea and leg fatigue increased significantly over time on both tests (P<0.05). The mean heart rate at the end of the sixth minute was significantly higher on the second test (P=0.022). Peripheral oxygen saturation remained above 90% in both tests. The furthest distance walked was, on average, 461.3 (SD 89.7)m. This value was significantly lower than that predicted for the sample (P<0.001). Patients scheduled to undergo abdominal surgery were able to walk further when they performed a second 6-minute walk test. Moreover, they showed reduced physical ability before surgery. These findings suggest that repetition of the 6-minute walk test may increase the accuracy of the distance walked, which is useful for studies assessing the physical capacity of patients undergoing abdominal surgery.

Background Tumors may induce systemic immune dysfunction, which can be aggravated by surgery and anesthesia/analgesia. Data on the effect of flurbiprofen preemptive analgesia on immune dysfunction is limited. The aim of this study was to investigate the effect of flurbiprofen preemptive analgesia on lymphocytes and natural killer (NK) cells in patients undergoing thoracotomy and thoracoscopy radical esophagectomy, and to explore the analgesic methods suitable for tumor patients. Methods This was a randomized controlled pilot study of 89 patients with esophageal cancer treated with surgery at the Henan Cancer Hospital between January 1, 2015 and December 31, 2016. The patients were divided into three groups: group 1, thoracotomy; group 2, thoracoscopy and laparoscopic surgery; and group 3, flurbiprofen, thoracoscopy, and laparoscopic surgery. CD3+, CD19+, NK, CD4+, and CD8+ cells in whole blood were measured by flow cytometry 30 minutes before surgery (T0), at the end of the thoracic section of the procedure (T1), and at the end of the operation (T2). Results There were no significant differences in CD3+, CD19+, CD8+, NK, and CD4+ cells between the three groups or regarding the time points during the procedure (all P > 0.05). Thoracotomy and thoracoscopy surgery resulted in similar immunological outcomes. Conclusion Flurbiprofen ester preemptive analgesia did not suppress the immune function in patients and could be a safe analgesic method for patients with esophageal cancer undergoing surgery.

Patients with glutaric aciduria type I are at risk for acute striatal injury precipitated by catabolic stress. Here, we report the successful interdisciplinary anesthetic and perioperative management of a child with glutaric aciduria type I undergoing cardiac surgery with extracorporeal circulation. Given the central focus on prevention of acute striatal injury, our anesthetic strategy emphasized avoiding a high protein load, high-dose inotropics, especially epinephrine (associated with impaired glucose utilization), deliberate hyperventilation, and other interventions associated with systemic inflammatory response.

In recent years, thoracic wall nerve blocks, such as the pectoral nerve (PECS) block and the serratus plane block have become popular for peri-operative pain control in patients undergoing breast cancer surgery. The effect of PECS block on quality of recovery (QoR) after breast cancer surgery has not been evaluated. To evaluate the ability of PECS block to decrease postoperative pain and anaesthesia and analgesia requirements and to improve postoperative QoR in patients undergoing breast cancer surgery. Randomised controlled study. A tertiary hospital. Sixty women undergoing breast cancer surgery between April 2014 and February 2015. The patients were randomised to receive a PECS block consisting of 30 ml of levobupivacaine 0.25% after induction of anaesthesia (PECS group) or a saline mock block (control group). The patients answered a 40-item QoR questionnaire (QoR-40) before and 1 day after breast cancer surgery. Numeric Rating Scale score for postoperative pain, requirement for intra-operative propofol and remifentanil, and QoR-40 score on postoperative day 1. PECS block combined with propofol-remifentanil anaesthesia significantly improved the median [interquartile range] pain score at 6 h postoperatively (PECS group 1 [0 to 2] vs. Control group 1 [0.25 to 2.75]; P = 0.018]. PECS block also reduced propofol mean (± SD) estimated target blood concentration to maintain bispectral index (BIS) between 40 and 50 (PECS group 2.65 (± 0.52) vs. Control group 3.08 (± 0.41) μg ml; P < 0.001) but not remifentanil consumption (PECS group 10.5 (± 4.28) vs. Control group 10.4 (± 4.68) μg kg h; P = 0.95). PECS block did not improve the QoR-40 score on postoperative day 1 (PECS group 182 [176 to 189] vs. Control group 174.5 [157.75 to 175]). In patients undergoing breast cancer surgery, PECS block combined with general anaesthesia reduced the requirement for propofol but not that for remifentanil, due to the inability of the PECS block to reach the internal mammary area. Further, PECS block improved postoperative pain but not the postoperative QoR-40 score due to the factors that cannot be measured by analgesia immediately after surgery, such as rebound pain. This trial is registered with the University Hospital Medical Information Network Clinical Trials Registry (UMIN000013435).

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.

There is a lack of published, validated questionnaires for evaluating psychosocial morbidity in patients with breast hypertrophy undergoing breast reduction surgery. To validate the breast evaluation questionnaire (BEQ), originally developed for the assessment of breast augmentation patients, for the assessment of psychosocial morbidity in patients with breast hypertrophy undergoing breast reduction surgery. Validation study Subjects: Women with macromastia Methods: The validation of the BEQ, adapted to breast reduction, was performed in several steps. Content validity, reliability, construct validity and responsiveness were assessed. The original version was adjusted according to the results for content validity and resulted in item reduction and a modified BEQ (mBEQ) that was then assessed for reliability, construct validity and responsiveness. Internal and external validation was performed for the modified BEQ. Convergent validity was tested against Breast-Q (reduction) and discriminate validity was tested against the SF-36. Known-groups validation revealed significant differences between the normal population and patients undergoing breast reduction surgery. The BEQ showed good reliability by test-re-test analysis and high responsiveness. The modified BEQ may be reliable, valid and responsive instrument for assessing women who undergo breast reduction.

Objective To determine whether the probability of undergoing coronary bypass surgery within a certain time was related to the number of patients on the wait list at registration for the operation in a publicly funded health system. Methods A prospective cohort study comparing waiting times among patients registered on wait lists at the hospitals delivering adult cardiac surgery. For each calendar week, the list size, the number of new registrations, and the number of direct admissions immediately after angiography characterized the demand for surgery. Results The length of delay in undergoing treatment was associated with list size at registration, with shorter times for shorter lists (log-rank test 1,198.3, p<.0001). When the list size at registration required clearance time over 1 week patients had 42 percent lower odds of undergoing surgery compared with lists with clearance time less than 1 week (odds ratio [OR] 0.58 percent, 95 percent, confidence interval [CI] 0.53–0.63), after adjustment for age, sex, comorbidity, period, and hospital. The weekly number of new registrations exceeding weekly service capacity had an independent effect toward longer service delays when the list size at registration required clearance time less than 1 week (OR 0.56 percent, 95 percent CI 0.45–0.71), but not for longer lists. Every time the operation was performed for a patient requiring surgery without registration on wait lists, the odds of surgery for listed patients were reduced by 6 percent (OR 0.94, CI 0.93–0.95). Conclusion For wait-listed patients, time to surgery depends on the list size at registration, the number of new registrations, as well as on the weekly number of patients who move immediately from angiography to coronary bypass surgery without being registered on a wait list. Hospital managers may use these findings to improve resource planning and to reduce uncertainty when providing advice on expected treatment delays. PMID:16430599

The use of a patient's image in plastic surgery is common today. Thus, plastic surgeons should master the use of the image and be aware of the implications of the patients' perception of themselves. The mere-exposure effect is a psychological phenomenon in which a person tends to rate things more positively merely because (s)he is familiar with them. Faces are asymmetric, so faces in photos are different from those observed in mirrors. The main objective of this study was to assess whether patients within a plastic surgery population, particularly those undergoing facial aesthetic surgery, preferred standard photographs or mirror-reversed photographs of themselves. A prospective study was conducted in a plastic surgery department, which included women who were admitted to the hospital the day before their procedures. The patients were separated into the following two groups: Group 1 was composed of patients who were undergoing facial aesthetic surgeries, and Group 2 consisted of other patients who presented to the plastic surgery department for surgery. The patients were required to rate their appreciation of their own faces and to choose between standard and mirror-reversed photos of themselves. A total of 214 patients participated. The median age was 47.9 years (interquartile range (IQR): 36.4-60.6), and the median face appreciation was 5 (IQR: 5-7). The preference for the mirror-reversed photograph was significantly different from chance (p < 0.001, binomial (214, 156, 0.5)); 73% of the patients preferred the mirror-reversed photographs. The proportions of patients who preferred the mirror-reversed photograph differed significantly (p = 0.047) between Groups 1 (84%) and 2 (70%). Plastic surgery patients have a significant preference for mirror-reversed photographs of themselves over standard photographs. This preference is even more pronounced among patients who are undergoing facial aesthetic surgery. III. Copyright © 2015 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Patients with cystic fibrosis (CF) frequently present with severe sinonasal disease often requiring radiologic imaging and surgical intervention. Few studies have focused on the relationship between radiologic scoring systems and the need for sinus surgery in this population. The objective of this study is to evaluate the Lund-Mackay (LM) and modified Lund-Mackay (m-LM) scoring systems in predicting the need for sinus surgery or revision surgery in patients with CF. We performed a retrospective chart review of CF patients undergoing computed tomography (CT) sinus imaging at a tertiary care pediatric hospital from 1995 to 2008. Patient scans were scored using both the LM and m-LM systems and compared to the rate of sinus surgery or revision surgery. Receiver-operator characteristics curves (ROC) were used to analyze the radiological scoring systems. A total of 41 children with CF were included in the study. The mean LM score for patients undergoing surgery was 17.3 (±3.1) compared to 11.5 (±6.2) for those treated medically (p<0.01). For the m-LM, the mean score of patients undergoing surgery was 20.3 (±3.5) and 13.5 (±7.3) for those medically treated (p<0.01). Using a ROC curve with a threshold score of 13 for the LM, the sensitivity was 89.3% (95% CI of 72-98) and specificity of 69.2% (95% CI of 39-91). At an optimal score of 19, the m-LM system produced a sensitivity of 67.7% (95% CI of 48-84) and specificity of 84.6% (95% CI of 55-98). The modified Lund-Mackay score provides a high specificity while the Lund-Mackay score a high sensitivity for CF patients who required sinus surgery. The combination of both radiologic scoring systems can potentially predict the need for surgery in this population. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Deep Vein Thrombosis After Complex Posterior Spine Surgery: Does Staged Surgery Make a Difference?

PubMed

Edwards, Charles C; Lessing, Noah L; Ford, Lisa; Edwards, Charles C

Retrospective review of a prospectively collected database. To assess the incidence of deep vein thrombosis (DVT) associated with single- versus multistage posterior-only complex spinal surgeries. Dividing the physiologic burden of spinal deformity surgery into multiple stages has been suggested as a potential means of reducing perioperative complications. DVT is a worrisome complication owing to its potential to lead to pulmonary embolism. Whether or not staging affects DVT incidence in this population is unknown. Consecutive patients undergoing either single- or multistage posterior complex spinal surgeries over a 12-year period at a single institution were eligible. All patients received lower extremity venous duplex ultrasonographic (US) examinations 2 to 4 days postoperatively in the single-stage group and 2 to 4 days postoperatively after each stage in the multistage group. Multivariate logistic regression was used to assess the independent contribution of staging to developing a DVT. A total of 107 consecutive patients were enrolled-26 underwent multistage surgery and 81 underwent single-stage surgery. The single-stage group was older (63 years vs. 45 years; p < .01) and had a higher Charlson comorbidity index (2.25 ± 1.27 vs. 1.23 ± 1.58; p < .01). More multistage patients had positive US tests than single-stage patients (5 of 26 vs. 6 of 81; 19% vs. 7%; p = .13). Adjusting for all the above-mentioned covariates, a multistage surgery was 8.17 (95% CI 0.35-250.6) times more likely to yield a DVT than a single-stage surgery. Patients who undergo multistage posterior complex spine surgery are at a high risk for developing a DVT compared to those who undergo single-stage procedures. The difference in DVT incidence may be understated as the multistage group had a lower pre- and intraoperative risk profile with a younger age, lower medical comorbidities, and less per-stage blood loss.

Specialization and high volume are reported to be related to a better outcome after abdominal aortic aneurysm repair. The aim of this study was to compare, in patients undergoing abdominal aortic aneurysm repair, the outcomes of those whose surgery was done by general surgeons with the outcomes of those whose surgery was done by specialist vascular surgeons. All patients undergoing abdominal aortic aneurysm repair at the Basel University Hospital (referral center) from January 1990 to December 2000 were included. Patients with endovascular treatment were excluded. Operations in group A (n = 189), between January 1990 and May 1995, were done by general surgeons. Operations in group B (n = 291), between June 1995 and December 2000, were done by vascular surgeons. In-hospital mortality and local and systemic complications were assessed. In-hospital mortality rates were significantly lower for group B (with specialist surgeons) than for group A, both overall (group B, 11.7%; group A, 21.7%; p = .003) and for emergency interventions (group B, 28.1%; group A, 41.9%; p = .042). The reduction in mortality for elective surgery in group B was not statistically significant (group B, 1.1%; group A, 4.9%; p = .054). There were significantly fewer pulmonary complications in group B compared with group A (p = .000). We conclude that in patients undergoing abdominal aortic aneurysm repair, those whose surgery is done by a specialized team have a significantly better outcome than those whose surgery is done by general surgeons.

The aim of the study was to determine if Sonoclot with its sensitive glass bead-activated, viscoelastic test can predict postoperative bleeding in patients undergoing cardiac surgery at predefined time points. A prospective, observational clinical study. A teaching hospital, single center. Consecutive patients undergoing cardiac surgery (N = 300). Besides routine laboratory coagulation studies and heparin management with standard (kaolin) activated clotting time, additional native blood samples were analyzed on a Sonoclot using glass bead-activated tests. Glass bead-activated clotting time, clot rate, and platelet function were recorded immediately before anesthesia induction and at the end of surgery after heparin reversal but before chest closure. Primary outcome was postoperative blood loss (chest tube drainage at 4, 8, and 12 hours postoperatively). Secondary outcome parameters were transfusion requirements, need for surgical re-exploration, time of mechanical ventilation, length of intensive care unit and hospital stay, and hospital morbidity and mortality. Patients were categorized into "bleeders" and "nonbleeders." Patient characteristics, operations, preoperative standard laboratory parameters, and procedural times were comparable between bleeders and nonbleeders except for sex and age. Bleeders had higher rates of transfusions, surgical re-explorations, and complications. Only glass bead measurements by Sonoclot after heparin reversal before chest closure but not preoperatively were predictive for increased postoperative bleeding. Sonoclot with its glass bead-activated tests may predict the risk for postoperative bleeding in patients undergoing cardiac surgery at the end of surgery after heparin reversal but before chest closure.

Coleman, Anne L; Yu, Fei; Evans, Stacy J

2006-12-01

The American Academy of Ophthalmology Preferred Practice Patterns for angle closure and open-angle glaucoma (OAG) patients recommends performing bilateral gonioscopy upon initial presentation to evaluate the possibility of narrow angle or angle-closure glaucoma (ACG) and then repeating the examination at least every 5 years. This study aims to assess how commonly eye care providers perform gonioscopy before planned glaucoma surgery in OAG, anatomic narrow angle, and ACG in the Medicare population. Data obtained from a 5% random sample of Medicare beneficiaries undergoing glaucoma surgery in the United States in 1999 were retrospectively reviewed. The proportion of patients with evidence of at least one gonioscopic examination before glaucoma surgery was determined for the period of 1995 to 1999. Demographic and clinical factors potentially influencing the decision to perform gonioscopy were also examined. Overall, gonioscopy is apparently performed in 49% of Medicare beneficiaries during the 4 to 5 years preceding glaucoma surgery. This rate was significantly lower (P < 0.001) in patients with OAG (46%), as compared with anatomic narrow angle (58%) and ACG (57%) patients. Hispanics, elderly (aged 70 to 84), patients undergoing laser iridotomy, and patients receiving care in the New York/New Jersey area all had significantly higher apparent preoperative gonioscopy rates (P < 0.05). Gonioscopy examination before glaucoma surgery in Medicare beneficiaries is underused, undercoded, and/or miscoded, given current recommendations. Underuse is of particular concern in patients undergoing laser iridotomy as it is the diagnostic test of choice in ACG.

Respiratory problems occur more frequently in patients who undergo open heart surgery. Intraoperative and postoperative ventilation strategies can prevent these complications and reduce mortality. We hypothesized that PCV would have better effects on gas exchange, lung mechanics and hemodynamics compared to VCV in CABG surgery. Our primary outcome was to compare the PaO 2 /FiO 2 ratio. Patients were randomized into two groups, (VCV, PCV) consisting of 30 individuals each. Two patients were excluded from the study. I/E ratio was adjusted to 1:2 and, RR:10/min fresh air gas flow was set at 3L/min in all patients. In the VCV group TV was set at 8 mL/kg of the predicted body weight. In the PCV group, peak inspiratory pressure was adjusted to the same tidal volume with the VCV group. PaO2/FiO2 was found to be higher with PCV at the end of the surgery. Time to extubation and ICU length of stay was shorter with PCV. Ppeak was similar in both groups. Pplateau was lower and Pmean was higher at the and of the surgery with PCV compared to VCV. The hemodynamic effects of both ventilation modes were found to be similar. PVC may be preferable to VCV in patients who undergo open heart surgery. However, it would be convenient if our findings are supported by similar studies.

Background Aortic stenosis is a frequent valvular disease especially in elderly patients. Catheter-based valve implantation has emerged as a valuable treatment approach for these patients being either at very high risk for conventional surgery or even deemed inoperable. The German Aortic Valve Registry (GARY) provides data on conventional and catheter-based aortic procedures on an all-comers basis. Methods and results A total of 13 860 consecutive patients undergoing repair for aortic valve disease [conventional surgery and transvascular (TV) or transapical (TA) catheter-based techniques] have been enrolled in this registry during 2011 and baseline, procedural, and outcome data have been acquired. The registry summarizes the results of 6523 conventional aortic valve replacements without (AVR) and 3464 with concomitant coronary bypass surgery (AVR + CABG) as well as 2695 TV AVI and 1181 TA interventions (TA AVI). Patients undergoing catheter-based techniques were significantly older and had higher risk profiles. The stroke rate was low in all groups with 1.3% (AVR), 1.9% (AVR + CABG), 1.7% (TV AVI), and 2.3% (TA AVI). The in-hospital mortality was 2.1% (AVR) and 4.5% (AVR + CABG) for patients undergoing conventional surgery, and 5.1% (TV AVI) and AVI 7.7% (TA AVI). Conclusion The in-hospital outcome results of this registry show that conventional surgery yields excellent results in all risk groups and that catheter-based aortic valve replacements is an alternative to conventional surgery in high risk and elderly patients.

The utility of routine preoperative electrocardiography (ECG) for assessing perioperative cardiovascular risk in patients undergoing noncardiac, nonvascular surgery (NCNVS) is unclear. There would be an association between preoperative ECG and perioperative cardiovascular outcomes in patients undergoing NCNVS. A total of 660 patients undergoing NCNVS were prospectively evaluated. Patients age >18 years who underwent an elective, nonday case, open surgical procedure were enrolled. Troponin I concentrations and 12-lead ECG were evaluated the day before surgery, immediately after surgery, and on the first 5 postoperative days. Preoperative ECG showing atrial fibrillation, left or right bundle branch block, left ventricular hypertrophy, frequent premature ventricular complexes, pacemaker rhythm, Q-wave, ST-segment changes, or sinus tachycardia or bradycardia were classified as abnormal. The patients were followed up during hospitalization and were evaluated for the presence of perioperative cardiovascular events (PCE). Eighty patients (12.1%) experienced PCE. Patients with abnormal ECG findings had a greater incidence of PCE than those with normal ECG results (16% vs 6.4%; P < 0.001). Mean QTc interval was significantly longer in the patients who had PCE (436.6 ± 31.4 vs 413.3 ± 16.7 ms; P < 0.001). Univariate analysis showed a significant association between preoperative atrial fibrillation, pacemaker rhythm, ST-segment changes, QTc prolongation, and in-hospital PCE. However, only QTc prolongation (odds ratio: 1.15, 95% confidence interval: 1.06-1.2, P < 0.001) was an independent predictor of PCE according to the multivariate analysis. Every 10-ms increase in QTc interval was related to a 13% increase for PCE. Prolongation of the QTc interval on the preoperative ECG was related with PCE in patients undergoing NCNVS. © 2011 Wiley Periodicals, Inc.

To evaluate racial disparities in the diagnosis and treatment of penile cancer among a contemporary series of men from a large diverse national data base. Using the 1998-2012 National Cancer Data Base, all men with squamous cell carcinoma (SCC) were stratified by race and ethnicity. Demographic and disease characteristics were compared between groups. Likelihood of undergoing surgery and type of surgery were compared among patients with nonmetastatic disease. Factors influencing disease stage and treatment type were analyzed with univariate and multivariable logistic regressions. Overall survival was examined with Kaplan-Meier and adjusted Cox proportional hazard models. We identified 12,090 men with penile SCC with median age 66 years (range 18-90). Distribution of patients is as follows: 76.8% Caucasian, 10.2% African American (AA), 8.7% Hispanic. On multivariable analysis, Hispanic men are more likely to present with high-risk (≥T1G3) penile SCC (odds ratio [OR] 1.6; confidence interval [CI] 1.20-2.00; P = .001) and tend to undergo penectomy rather than penile-sparing surgery (OR 1.46; CI 1.15-1.85; P = .002) for equal stage SCC compared to Caucasian patients. Whereas AA men are less likely to undergo surgery of any type (OR 0.67; CI 0.51-0.87; P = .003) and have higher mortality rates than Caucasian patients (hazard ratio 1.25; CI 1.10-1.42; P < .001). Hispanic men with penile SCC are more likely to present with high-risk disease and undergo more aggressive treatment than Caucasian patients but have comparable survival. AA men are less likely to undergo surgical management of their disease and have higher mortality rates. Copyright © 2016 Elsevier Inc. All rights reserved.

2017-04-15

CASE DESCRIPTION A 12-year-old neutered male domestic shorthair cat had been treated for a mass arising from the lingual aspect of the caudal right mandibular body. Cytoreductive surgery of the mass had been performed twice over a 2-year period, but the mass recurred following both surgeries. The mass was diagnosed as an osteosarcoma, and the cat was referred for further evaluation and treatment. CLINICAL FINDINGS Clinical findings were unremarkable, except for a 2-cm-diameter mass arising from the lingual aspect of the right mandible and mild anemia and lymphopenia. Pre- and postcontrast CT scans of the head, neck, and thorax were performed, revealing that the osteosarcoma was confined to the caudal right mandibular body, with no evidence of lymph node or pulmonary metastasis. TREATMENT AND OUTCOME The stereolithographic files of the CT scan of the head were sent for computer-aided design and manufacture of a customized 3-D-printed titanium prosthesis. Segmental mandibulectomy was performed, and the mandibular defect was reconstructed in a single stage with the 3-D-printed titanium prosthesis. The cat had 1 minor postoperative complication but had no signs of eating difficulties at any point after surgery. The cat was alive and disease free 14 months postoperatively. CLINICAL RELEVANCE Reconstruction of the mandible of a cat following mandibulectomy was possible with computer-aided design and manufacture of a customized 3-D-printed titanium prosthesis. Cats have a high rate of complications following mandibulectomy, and these initial findings suggested that mandibular reconstruction may reduce the risk of these complications and result in a better functional outcome.

The purpose of this study was to investigate the outcomes and prognostic factors of metastasectomy in patients with metastatic ovarian tumors from extragenital primary sites. All patients with pathologically confirmed metastatic ovarian tumors between January 1997 and June 2015 were included in this study. A total of 131 patients were identified. The data were obtained from the patients' medical records. Clinicopathological features were evaluated by both univariate and multivariate analyses. The primary sites were colorectal region (53.4%), stomach (26%), and breast (13%). Preoperative serum CA 125 and CA 19-9 levels were elevated in 29.4% and 39.8% of the patients, respectively. Cytoreductive surgery was performed in 41.2% of the patients. Seventy-three (55.7%) patients had no residual disease after surgery. Sixty-six (49.6%) patients had combined metastases at the time of the surgery to sites including the liver, pancreas, lung, bone, lymph nodes, bladder, or the intestine. With a median follow-up of 33 months, the median survival time was 22 months. The estimated 5-year survival probability is 0.26. On univariate analysis, primary cancer site, combined metastasis outside the ovaries, residual disease, preoperative serum CA 125 and CA 19-9 levels, and histologic type were significant parameters for overall survival. Furthermore, residual disease, preoperative serum CA 19-9 level, and primary cancer site were found to be independent prognostic factors on multivariate analysis. The most common primary sites for ovarian metastasis are gastrointestinal tract. Metastasectomy may have beneficial effects on survival, especially if the residual disease is less than 5 mm. Prospective studies warranted to evaluate the value of metastasectomy in patients with ovarian metastasis.

To describe the successful perioperative hemostatic management of a Jehovah's Witness patient with hemophilia B and anaphylactic inhibitors to factor IX, undergoing scoliosis surgery. A 14 (1/2)-yr-old boy with severe hemophilia B who had a history of anaphylactic inhibitors to factor IX was scheduled to undergo corrective scoliosis surgery. He was initially started on epoetin alfa and iron supplementation to maximize preoperative red cell mass. Additionally, he was placed on a desensitization protocol of recombinant coagulation factor IX (rFIX) and was then treated with activated recombinant coagulation factor VII (rFVIIa) during the postoperative period. Tranexamic acid was given concomitantly. The intraoperative blood loss was approximately 350 mL. The nadir hemoglobin concentration was 111 g.L(-1) on postoperative days one and two. On postoperative day 11, the patient was stable and discharged home with a hemoglobin of 138 g.L(-1). He did not require blood transfusion and no adverse events were observed. The use of rFIX, rFVIIa, erythropoetin, iron, and tranexamic acid before, during and after scoliosis surgery may be a viable and safe option for hemophilia patients with inhibitors, who refuse blood products.

The number of adolescents undergoing weight loss surgery (WLS) has increased in response to the increasing prevalence of severe childhood obesity. Adolescents undergoing WLS require unique support, which may differ from adult programs. The aim of this study was to describe institutional and programmatic characteristics of centers participating in Teen Longitudinal Assessment of Bariatric Surgery (Teen-LABS), a prospective study investigating safety and efficacy of adolescent WLS. Data were obtained from the Teen-LABS database, and site survey completed by Teen-LABS investigators. The survey queried (1) institutional characteristics, (2) multidisciplinary team composition, (3) clinical program characteristics, and (4) clinical research infrastructure. All centers had extensive multidisciplinary involvement in the assessment, pre-operative education, and post-operative management of adolescents undergoing WLS. Eligibility criteria and pre-operative clinical and diagnostic evaluations were similar between programs. All programs have well-developed clinical research infrastructure, use adolescent-specific educational resources, and maintain specialty equipment, including high weight capacity diagnostic imaging equipment. The composition of clinical team and institutional resources is consistent with current clinical practice guidelines. These characteristics, coupled with dedicated research staff, have facilitated enrollment of 242 participants into Teen-LABS. © 2013 Published by Elsevier Inc.

Background The number of adolescents undergoing weight loss surgery (WLS) has increased in response to the increasing prevalence of severe childhood obesity. Adolescents undergoing WLS require unique support, which may differ from adult programs. The aim of this study was to describe institutional and programmatic characteristics of centers participating in Teen-Longitudinal Assessment of Bariatric Surgery (Teen-LABS), a prospective study investigating safety and efficacy of adolescent WLS. Methods Data were obtained from the Teen-LABS database and site survey completed by Teen-LABS investigators. The survey queried (1) institutional characteristics, (2) multidisciplinary team composition, (3) clinical program characteristics, and (4) clinical research infrastructure. Results All centers had extensive multidisciplinary involvement in the assessment, preoperative education and post-operative management of adolescents undergoing WLS. Eligibility criteria, pre-operative clinical and diagnostic evaluations were similar between programs. All programs have well developed clinical research infrastructure, use adolescent-specific educational resources, and maintain specialty equipment, including high weight capacity diagnostic imaging equipment. Conclusions The composition of clinical team and institutional resources are consistent with current clinical practice guidelines. These characteristics, coupled with dedicated research staff, have facilitated enrollment of 242 participants into Teen-LABS. PMID:24491361

To measure the release of plasma nuclear deoxyribonucleic acid (DNA) and to assess the relationship between nuclear DNA level and acute kidney injury occurrence in patients undergoing cardiac surgery. Cardiovascular anesthesiology and intensive care unit of a large tertiary-care university hospital. Prospective observational study. Fifty adult patients undergoing cardiac surgery. Nuclear DNA concentration was measured in the plasma. The relationship between the level of nuclear DNA and the incidence of acute kidney injury after coronary artery bypass grafting was investigated. Cardiac surgery leads to significant increase in plasma nuclear DNA with peak levels 12 hours after surgery (median [interquartile range] 7.0 [9.6-22.5] µg/mL). No difference was observed between off-pump and on-pump surgical techniques. Nuclear DNA was the only predictor of acute kidney injury between baseline and early postoperative risk factors. The authors found an increase of nuclear DNA in the plasma of patients who had undergone coronary artery bypass grafting, with a peak after 12 hours and an association of nuclear DNA with postoperative acute kidney injury.

Owing to advances in cardiovascular surgery, patients with cardiovascular disease require improvement of health-related quality of life (QOL) than before. We measured the QOL of patients undergoing cardiovascular surgery using the eight-item Short Form (SF-8) and assessed its usefulness. This was a prospective repeated-measures observational study. The SF-8 questionnaire was completed through interviews with 117 consecutive adult patients undergoing cardiovascular surgery at a single center (Nagara Medical Center, Japan) from April 2006 to March 2008. The SF-8 was evaluated before surgery and at 7 days, 1 month, and 6 months after surgery. The physical and mental scores over time were assessed. Regarding physical status, compared with the normal population, the patients' scores were worse preoperatively and had deteriorated 7 days postoperatively; they gradually got closer to preoperative status a month after the procedure. At 6 months after surgery, all physical scores were higher than before surgery. The mental scores, including a mental component summary score, were inferior to those of the normal population until 1 month postoperatively, and they reached those of the normal population at 6 months. The SF-8 changed with the postoperative time course. It was a useful tool for analyzing the physical and mental QOL of patients who underwent cardiovascular surgery.

Obesity is an important consideration in neurosurgical practice. Of Australian adults, 28.3% are obese and it is estimated that more than two thirds of Australia's population will be overweight or obese by 2025. This review of the effects of obesity on neurosurgical procedures shows that, in patients undergoing spinal surgery, an increased body mass index is a significant risk factor for surgical site infection, venous thromboembolism, major medical complications, prolonged length of surgery, and increased financial cost. Although outcome scores and levels of patient satisfaction are generally lower after spinal surgery in obese patients, obesity is not a barrier to deriving benefit from surgery and, when the natural history of conservative management is taken into account, the long-term benefits of surgery may be equivalent or even greater in obese patients than in nonobese patients. In cranial surgery, the impact of obesity on outcome and complication rates is generally lower. Specific exceptions are higher rates of distal catheter migration after shunt surgery and cerebrospinal fluid leak after posterior fossa surgery. Minimally invasive approaches show promise in mitigating some of the adverse effects of obesity in patients undergoing spine surgery but further studies are needed to develop strategies to reduce obesity-related surgical complications.

Background: Problems regarding bowel elimination are quite common in patients undergoing abdominal surgery. Objectives: To determine constipation risk before the surgery, bowel elimination during postoperative period, and the factors affecting bowel elimination. Patients and Methods: This is a cross-sectional study. It was conducted in a general surgery ward of a university hospital in Zonguldak, Turkey between January 2013 and May 2013. A total of 107 patients were included in the study, who were selected by convenience sampling. Constipation Risk Assessment Scale (CRAS), patient information form, medical and nursing records were used in the study. Results: The mean age of the patients was found to be 55.97 ± 15.74 (year). Most of the patients have undergone colon (37.4%) and stomach surgeries (21.5%). Open surgical intervention (83.2%) was performed on almost all patients (96.3%) under general anesthesia. Patients were at moderate risk for constipation with average scores of 11.71 before the surgery. A total of 77 patients (72%) did not have bowel elimination problem during postoperative period. The type of the surgery (P < 0.05), starting time for oral feeding after the surgery (P < 0.05), and mobilization (P < 0.05) were effective on postoperative bowel elimination. Conclusions: There is a risk for constipation after abdominal surgery. Postoperative practices are effective on the risk of constipation. PMID:26380107

There has been an alarming worldwide increase of obese people in recent years. Currently, there is no consensus on whether patients that are scheduled to undergo bariatric surgery should lose weight before the intervention. The objective of this research is to analyse the influence of pre-surgery loss of weight in the nutritional parameters of patients. Fifty patients that were scheduled to undergo bariatric surgery followed a very low caloric diet during 4 weeks prior to the surgery. The nutritional parameters were analysed at 3 specific moments: before starting the diet, at the moment of surgery (when the diet was concluded) and one month after the surgery. Average values for hemoglobin, albumina and lymphocytes were kept within the range of normal values at all moments, even though the decrease of those parameters was statistically significant throughout the study (P<.05). By following the very low caloric diet, less than 9.5% of the sample suffered anaemia. Loss of weight prior to surgery does not have a significant influence in the nutritional parameters of the patient. These results would support the indication of losing weight for patients that are considered candidates for bariatric surgery. Copyright © 2014 AEC. Publicado por Elsevier España, S.L.U.

This study was designed to evaluate the effectiveness of lavender aromatherapy on pain, anxiety, and level of satisfaction associated with the peripheral venous cannulation (PVC) in patients undergoing surgery. One hundred and six patients undergoing surgery were randomized to receive aromatherapy with lavender essential oil (the lavender group) or a placebo (the control group) during PVC. The patients' pain, anxiety, and satisfaction scores were measured. There was no statistically significantly difference between the groups in terms of demographic data. After cannulation, the pain and anxiety scores (anxiety 2) of the patients in the lavender group were significantly lower than the control group (for p = 0.01 for pain scores; p < 0.001 for anxiety 2 scores). In addition, patient satisfaction was significantly higher in the lavender group than in the control group (p = 0.003). Lavender aromatherapy had beneficial effects on PVC pain, anxiety, and satisfaction level of patients undergoing surgery. Copyright © 2016 Elsevier Ltd. All rights reserved.

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.

Patients undergoing minimally invasive cardiac surgery have the potential for significant pain from the thoracotomy site. We report the successful use of pectoral nerve block types I and II (Pecs I and II) as rescue analgesia in a patient undergoing minimally invasive mitral valve repair. In this case, a 78-year-old man, with no history of chronic pain, underwent mitral valve repair via right anterior thoracotomy for severe mitral regurgitation. After extubation, he complained of 10/10 pain at the incision site that was minimally responsive to intravenous opioids. He required supplemental oxygen because of poor pulmonary mechanics, with shallow breathing and splinting due to pain, and subsequent intensive care unit readmission. Ultrasound-guided Pecs I and II blocks were performed on the right side with 30 mL of 0.2% ropivacaine with 1:400,000 epinephrine. The blocks resulted in near-complete chest wall analgesia and improved pulmonary mechanics for approximately 24 hours. After the single-injection blocks regressed, a second set of blocks was performed with 266 mg of liposomal bupivacaine mixed with bupivacaine. This second set of blocks provided extended analgesia for an additional 48 hours. The patient was weaned rapidly from supplemental oxygen after the blocks because of improved analgesia. Pectoral nerve blocks have been described in the setting of breast surgery to provide chest wall analgesia. We report the first successful use of Pecs blocks to provide effective chest wall analgesia for a patient undergoing minimally invasive cardiac surgery with thoracotomy. We believe that these blocks may provide an important nonopioid option for the management of pain during recovery from minimally invasive cardiac surgery.

Music has been proposed as a safe, inexpensive, nonpharmacological antistress intervention. The purpose of this study was to determine whether patients undergoing cataract surgery while listening to meditation music experience lower levels of blood pressure and heart rate. Two hundred individuals undergoing cataract surgery participated in the study. Hundred individuals listened to meditation music, through headphones, before and during the operation (intervention group) and 100 individuals received standard care (control group). Patients stress coping skills were measured by the Sense of Coherence Scale (SOC Scale). Systolic and diastolic blood pressure and heart rate were defined as outcome measures. According to the SOC Scale, both groups had similar stress coping skills (mean score: 127.6 for the intervention group and 127.3 for the control group). Before entering the operating room (OR) as well as during surgery the rise in systolic and diastolic pressures was significantly lower in the intervention group (P < 0.001). Among patients receiving antihypertensive therapy, those in the intervention group presented a lower increase only in systolic pressure (P < 0.001) at both time recordings. For those patients in the intervention group who did not receive antihypertensive treatment, lower systolic blood pressure at both time recordings was recorded (P < 0.001) while lower diastolic pressure was observed only during entry to the OR (P = 0.021). Heart rate was not altered between the two groups in any of the recordings. Meditation music influenced patients' preoperative stress with regard to systolic blood pressure. This kind of music can be used as an alternative or complementary method for blood pressure stabilizing in patients undergoing cataract surgery.

Although it has been widely demonstrated that administration of Daikenchuto (DKT), a traditional Japanese herbal medicine, improves gastrointestinal (GI) motility in patients undergoing abdominal surgery, few studies have investigated the efficacy of perioperative DKT administration for relief of postoperative ileus (PI) in patients undergoing surgery for GI cancer. Therefore, the aim of this study was to investigate whether perioperative administration of DKT relieves PI in patients with GI cancer. We performed a comprehensive electronic search of the literature (Cochrane Library, PubMed, the Web of Science and ICHUSHI) up to December 2016 to identify studies that had shown the efficacy of perioperative DKT administration for relief of PI in patients with GI cancer. To integrate the individual effect of DKT, a meta-analysis was performed using random-effects models to calculate the risk ratio (RR) and 95% confidence interval (CI), and heterogeneity was analyzed using I 2 statistics. Seven studies involving a total of 1,134 patients who had undergone GI cancer surgery were included in this meta-analysis. Among 588 patients who received DKT perioperatively, 67 (11.4%) had PI, whereas among 546 patients who did not receive DKT perioperatively, 87 (15.9%) had PI. Perioperative administration of DKT significantly reduced the occurrence of PI (RR=0.58, 95% CI=0.35-0.97, p=0.04, I 2 =48%) in comparison to patients who did not receive DKT or received placebo. The result of this meta-analysis suggests that perioperative administration of DKT relieves PI in patients undergoing surgery for GI cancer.

Nutritional status has major impacts on the outcome of surgery, in particular in patients with cancer. The aim of this review was to assess the merit of oral pre-operative nutritional support as a part of prehabilitation in patients undergoing surgery for colorectal cancer. A systematic literature search and meta-analysis was performed according to the Preferred Reporting of Systematic Reviews and Meta-Analyses (PRISMA) recommendations in order to review all trials investigating the effect of oral pre-operative nutritional support in patients undergoing colorectal surgery. The primary outcome was overall complication rate. Secondary outcomes were incision infection rate, anastomotic leakage rate, and length of hospital stay. Five randomized controlled trials and one controlled trial were included. The studies contained a total of 583 patients with an average age of 63 y (range 23-88 y), of whom 87% had colorectal cancer. Malnourishment rates ranged from 8%-68%. All investigators provided an oral protein supplement. Overall patient compliance rates ranged from 72%-100%. There was no significant reduction in the overall complication rate in the interventional groups (odds ratio 0.82; 95% confidence interval 0.52 - 1.25). Current studies are too heterogeneous to conclude that pre-operative oral nutritional support could enhance the condition of patients undergoing colorectal surgery. Patients at risk have a relatively lean body mass deficit (sarcopenia) rather than an absolute malnourished status. Compliance is an important element of prehabilitation. Targeting patients at risk, combining protein supplements with strength training, and defining standardized patient-related outcomes will be essential to obtain satisfactory results.

Postoperative hyperglycaemia of diabetic patients undergoing cardiac surgery - a clinical audit.

Previous studies have shown that hyperglycaemia is associated with postoperative complications in cardiac surgical patients. Conversely, well-controlled glucose levels are said to reduce major infectious complications in diabetic patients. The purpose of this clinical audit was to evaluate the blood glucose levels of diabetic patients undergoing cardiac surgery and to determine the effectiveness of postoperative glycaemic control. A group of 150 patients from a large Irish cardiac surgery centre was selected by convenience sampling. An audit tool was designed to capture the patients' blood glucose levels, treatment regimes and postoperative complications. The findings showed major variations between 'high', 'good' and 'borderline' blood glucose levels in the pre- and postoperative phase. Although blood glucose testing practices seemed inconsistent, mean levels measured 'borderline'. Furthermore, the treatment regimes varied greatly and suggest a lack of consensus regarding the management of postoperative hyperglycaemia. A total of 52% (n = 78) patients developed 114 complications with a level of 21.4% (n = 32) postoperative wound infections. The findings from this audit highlight the importance of regular blood glucose testing to enable early detection of hyperglycaemia and timely initiation of appropriate treatments regimes for diabetic patients undergoing cardiac surgery. Findings also show that hyperglycaemia derangement may make a difference in the recovery phase. While patients will benefit from lesser wound infections, hospitals might save costs involved with treating postoperative complications. More consistent blood glucose testing might be achieved through the use of evidence-based protocols. However, the education of staff is as important as it develops knowledge on the complex metabolic interactions of diabetic patients undergoing cardiac surgery. While this means investing in staff education and policy development, costs for daily care and expensive treatments for complications will be saved as patient recovery will be speedier and less eventful.

To study innate immune pathways in patients undergoing hepatopancreaticobiliary surgery to understand mechanisms leading to enhanced inflammatory responses and identifying biomarkers of adverse clinical consequences. Patients undergoing major abdominal surgery are at risk of life-threatening systemic inflammatory response syndrome (SIRS) and sepsis. Early identification of at-risk patients would allow tailored postoperative care and improve survival. Two separate cohorts of patients undergoing major hepatopancreaticobiliary surgery were studied (combined n = 69). Bloods were taken preoperatively, on day 1 and day 2 postoperatively. Peripheral blood mononuclear cells and serum were separated and immune phenotype and function assessed ex vivo. Early innate immune dysfunction was evident in 12 patients who subsequently developed SIRS (postoperative day 6) compared with 27 who did not, when no clinical evidence of SIRS was apparent (preoperatively or days 1 and 2). Serum interleukin (IL)-6 concentration and monocyte Toll-like receptor (TLR)/NF-κB/IL-6 functional pathways were significantly upregulated and overactive in patients who developed SIRS (P < 0.0001). Interferon α-mediated STAT1 phosphorylation was higher preoperatively in patients who developed SIRS. Increased TLR4 and TLR5 gene expression in whole blood was demonstrated in a separate validation cohort of 30 patients undergoing similar surgery. Expression of TLR4/5 on monocytes, particularly intermediate CD14CD16 monocytes, on day 1 or 2 predicted SIRS with accuracy 0.89 to 1.0 (areas under receiver operator curves). These data demonstrate the mechanism for IL-6 overproduction in patients who develop postoperative SIRS and identify markers that predict patients at risk of SIRS 5 days before the onset of clinical signs.

Xenon was shown to cause less hemodynamic instability and reduce vasopressor needs during off-pump coronary artery bypass (OPCAB) surgery when compared with conventionally used anesthetics. As xenon exerts its organ protective properties even in subanesthetic concentrations, we hypothesized that in patients undergoing OPCAB surgery, 30% xenon added to general anesthesia with propofol results in superior hemodynamic stability when compared to anesthesia with propofol alone. Fifty patients undergoing elective OPCAB surgery were randomized to receive general anesthesia with 30% xenon adjuvant to a target-controlled infusion of propofol or with propofol alone. The primary end point was the total intraoperative dose of norepinephrine required to maintain an intraoperative mean arterial pressure >70 mm Hg. Secondary outcomes included the perioperative cardiorespiratory profile and the incidence of adverse and serious adverse events. Adding xenon to propofol anesthesia resulted in a significant reduction of norepinephrine required to attain the predefined hemodynamic goals (cumulative intraoperative dose: median [interquartile range]: 370 [116-570] vs 840 [335-1710] µg, P = .001). In the xenon-propofol group, significantly less propofol was required to obtain a similar depth of anesthesia as judged by clinical signs and the bispectral index (propofol effect site concentration [mean ± SD]: 1.8 ± 0.5 vs 2.8 ± 0.3 mg, P≤ .0001). Moreover, the xenon-propofol group required significantly less norepinephrine during the first 24 hours on the intensive care unit (median [interquartile range]: 1.5 [0.1-7] vs 5 [2-8] mg, P = .048). Other outcomes and safety parameters were similar in both groups. Thirty percent xenon added to propofol anesthesia improves hemodynamic stability by decreasing norepinephrine requirements in patients undergoing OPCAB surgery.

Speckle tracking, when combined with 3-dimensional (3D) left ventricular ejection fraction, might prove to be a more sensitive marker for postoperative ventricular dysfunction. This study investigated early outcomes in a cohort of patients with left ventricular dysfunction undergoing cardiac surgery. Prospective, blinded, observational study. University hospital; single institution. The study comprised 73 adult patients with left ventricular ejection fraction <50% undergoing cardiac surgery using cardiopulmonary bypass. Routine transesophageal echocardiography before and after bypass. Global longitudinal strain using speckle tracking and 3D left ventricular ejection fraction were computed using transesophageal echocardiography. Mean prebypass global longitudinal strain and 3D left ventricle ejection fraction were significantly lower in patients with postoperative low-cardiac-output syndrome compared with patients who did not develop low cardiac output (global longitudinal strain -7.5% v -10.7% and 3D left ventricular ejection fraction 29% v 39%, respectively; p < 0.0001). The cut-off value of global longitudinal strain predicting postoperative low-cardiac-output syndrome was -6%, with 95% sensitivity and 68% specificity; and 3D left ventricular ejection fraction was 19% with 98% sensitivity and 81% specificity. Preoperative left ventricular global longitudinal strain (-6%) and 3D left ventricular ejection fraction (19%) together could act as predictor of postoperative low-cardiac-output states with high sensitivity (99.9%) in patients undergoing cardiac surgery.

With the withdrawal of aprotinin from worldwide marketing in November 2007, many institutions treating patients at high risk for hyperfibrinolysis had to update their therapeutic protocols. At our institution, the standard was switched from aprotinin to ε-aminocaproic acid (EACA) in all patients undergoing cardiac surgery with extracorporeal circulation including neonates. Although both antifibrinolytic medications have been used widely for many years, there are few data directly comparing their blood-sparing effect and their side-effects especially in neonates. Perioperative data from 235 neonates aged up to 30 days undergoing primary cardiac surgery were analysed. Between July 1, 2006 and November 5, 2007, all patients (n=95) received aprotinin. Starting November 6, 2007 until December 31, 2009, all patients (n=140) were treated with EACA. The primary outcome criterion was blood loss; secondary outcome criteria were transfusion requirements, renal, vascular, and neurological complications and also in-hospital mortality. All descriptive and intraoperative data variable were similar. Blood loss was significantly higher in the EACA group (P=0.001), but there was no difference in the rate of re-operation for bleeding (P=0.218) nor the number of transfusions. There were no differences in the incidences of postoperative renal, neurological, and vascular events or in-hospital mortality. In neonatal patients undergoing cardiac surgery, the switch to EACA treatment led to a higher postoperative blood loss. However, there were no differences in transfusion requirements or major clinical outcomes.

Background Percutaneous coronary intervention (PCI) is sometimes performed with the intent to lower cardiovascular risk before high‐risk noncardiac surgery (HRNCS). There are limited data on the frequency and outcome of PCIs performed in this setting. Methods and Results We assessed the frequency, characteristics, and in‐hospital outcomes of patients undergoing PCI as part of the preoperative workup for HRNCS among all 61 145 elective PCIs performed between 2002 and 2009 at 14 hospitals in the Blue Cross Blue Shield of Michigan Cardiovascular Consortium. Propensity matching was performed to compare outcomes of patients undergoing PCI before HRNCS with all other elective PCI patients. The frequency of PCI before HRNCS was low (4.2%). Patients undergoing PCI before HRNCS were older (67.3 versus 64.9 years, P<0.0001) and had a greater burden of comorbidity. Patients undergoing PCI before HRNCS had an increase in unadjusted major adverse cardiovascular events, postprocedure transfusion, contrast‐induced nephropathy, nephropathy requiring dialysis, and same‐admission coronary artery bypass graft surgery, but there was no difference in mortality (0.27% versus 0.14%, P=0.11). However, in propensity score–matched samples, there was a significant difference only in nephropathy requiring dialysis. Conclusions The incidence of PCI performed in preparation for high‐risk noncardiac surgery is low, and these procedures are currently being performed on a highly selected high‐risk patient population.

Atelectasis and pleural effusion are common after coronary artery bypass graft surgery (CABG). Longer stay in the bed is one of the most important contributing factors in pulmonary complications. Some studies confirm the benefits of early mobilization (EM) in critically ill patients, but the efficacy of EM on pulmonary complications after CABG is not clear. This study was designed to examine the effect of EM on the incidence of atelectasis and pleural effusion in patients undergoing CABG. In a single-blinded randomized clinical trial, 100 patients who were undergoing coronary artery bypass graft surgery were randomly assigned into two groups each consisted of 50 patients. Patients in the experimental group were enrolled in a mobilization protocol consisting of the mobilization from the bed in the first 3 days after surgery in the morning and evening. Patients in the control group were mobilized from bed in third postoperation day, according to the hospital routine. Arterial blood gases, pleural effusion, and atelectasis were compared between groups. Atelectasis and pleural effusion was reduced in experimental group. The partial pressure of oxygen in arterial blood in third postoperative day and the percentage of arterial oxygen saturation in the fourth postoperative day were higher in the intervention group (P value < .05). EM from bed could be an effective intervention in reducing atelectasis and pleural effusion in patients undergoing CABG. Copyright © 2017 Society for Vascular Nursing, Inc. Published by Elsevier Inc.

BACKGROUND Post-operative cognitive dysfunction (POCD) demarks cognitive decline after major surgery but has been studied to date in “healthy” adults. Although individuals with neurodegenerative disorders such as Parkinson’s disease (PD) commonly undergo elective surgery, these individuals have yet to be prospectively followed despite hypotheses of increased POCD risk. OBJECTIVE To conduct a pilot study examining cognitive change pre-post elective orthopedic surgery for PD relative to surgery and non-surgery peers. METHODS A prospective one-year longitudinal design. No-dementia idiopathic PD individuals were actively recruited along with non-PD “healthy” controls (HC) undergoing knee replacement surgery. Non-surgical PD and HC controls were also recruited. Attention/processing speed, inhibitory function, memory recall, animal (semantic) fluency, and motor speed were assessed at baseline (pre-surgery), three-weeks, three-months, and one-year post- orthopedic surgery. Reliable change methods examined individual changes for PD individuals relative to control surgery and control non-surgery peers. RESULTS Over two years we screened 152 older adult surgery or non-surgery candidates with 19 of these individuals having a diagnosis of PD. Final participants included 8 PD (5 surgery, 3 non-surgery), 47 Control Surgery, and 21 Control Non-Surgery. Eighty percent (4 of the 5) PD surgery declined greater than 1.645 standard deviations from their baseline performance on measures assessing processing speed and inhibitory function. This was not observed for the non-surgery PD individuals. CONCLUSION This prospective pilot study demonstrated rationale and feasibility for examining cognitive decline in at-risk neurodegenerative populations. We discuss recruitment and design challenges for examining post-operative cognitive decline in neurodegenerative samples. PMID:26683785

Laparoscopic surgery requires inflation of the abdominal cavity and this offers a unique opportunity to measure the mechanical properties of the living abdominal wall. We used a motion analysis system to study the abdominal wall motion of 18 patients undergoing laparoscopic surgery, and found that the mean Young's modulus was 27.7+/-4.5 and 21.0+/-3.7 kPa for male and female, respectively. During inflation, the abdominal wall changed from a cylinder to a dome shape. The average expansion in the abdominal wall surface was 20%, and a working space of 1.27 x 10(-3)m(3) was created by expansion, reshaping of the abdominal wall and diaphragmatic movement. For the first time, the elasticity of human abdominal wall was obtained from the patients undergoing laparoscopic surgery, and a 3D simulation model of human abdominal wall has been developed to analyse the motion pattern in laparoscopic surgery. Based on this study, a mechanical abdominal wall lift and a surgical simulator for safe/ergonomic port placements are under development.

Cutaneous and respiratory insensible perspiration were studied in patients during anaesthesia and surgery. The evaporative water loss from the respiratory tract was studied in 27 patients undergoing abdominal surgery. The method used was based on a fast-acting aspiration psychrometer, and the expired gases were heated so that no condensation could occur before the gases reached the psychrometer. The evaporative water loss from the skin was studied in 18 patients undergoing abdominal surgery. The method used was based on estimation of the vapour pressure gradient immediately adjacent to the surface of the skin. It was shown that the evaporative water and heat loss from the respiratory tract during surgery amount to about 10 g.m-2.h-1, resp. 25kJ.m-2.h-1, which is a 15% increase in comparison with normal breathing in an indoor environment. The loss from the skin was about 10 g.m-2.h-1, which does not differ from results obtained in healthy individuals in a corresponding environment.

Retrospective study of 407 patients and reports on chest X-rays carried out before and after bariatric surgery over a period of 14 months. Only patients who underwent bariatric surgery by laparotomy were included. There was an overall prevalence of 37.84% of atelectasis, with the highest prevalence in the lung bases and with greater prevalence in women (RR=1.48). There was a ratio of 30% for the influence of age for individuals under the age of 36, and of 45% for those older than 36 (RR=0.68). There was no significant influence of BMI on the prevalence of atelectasis. The prevalence of atelectasis in bariatric surgery is 37% and the main risk factors are being female and aged over 36 years. Copyright © 2016. Publicado por Elsevier Editora Ltda.

Cardiac surgery-associated acute kidney injury.

2014-05-01

Acute kidney injury develops in up to 30% of patients who undergo cardiac surgery, with up to 3% of patients requiring dialysis. The requirement for dialysis after cardiac surgery is associated with an increased risk of infection, prolonged stay in critical care units and long-term need for dialysis. The development of acute kidney injury is independently associated with substantial short- and long-term morbidity and mortality. Its pathogenesis involves multiple pathways. Haemodynamic, inflammatory, metabolic and nephrotoxic factors are involved and overlap each other leading to kidney injury. Clinical studies have identified predictors for cardiac surgery-associated acute kidney injury that can be used effectively to determine the risk for acute kidney injury in patients undergoing cardiac surgery. High-risk patients can be targeted for renal protective strategies. Nonetheless, there is little compelling evidence from randomized trials supporting specific interventions to protect or prevent acute kidney injury in cardiac surgery patients. Several strategies have shown some promise, including less invasive procedures in those at greatest risk, natriuretic peptide, fenoldopam, preoperative hydration, preoperative optimization of anaemia and postoperative early use of renal replacement therapy. The efficacy of larger-scale trials remains to be confirmed.

The eruption of the first and second permanent molar teeth may influence the size of the retromolar space. In this study we evaluated the adequacy of the retromolar space for retromolar intubation and any effect of eruption of the first and second permanent molar teeth on this space in children. Children 3-15 yr of age, undergoing surgery other than facial surgery were included for evaluation of the retromolar space. After standard oral tracheal intubation, the endotracheal tube was shifted to the retromolar space and the mandible was slowly closed to achieve centric occlusion. At the same time, any increase in airway resistance or decrease in oxygen saturation was noted. In the second part of the study, the feasibility of retromolar intubation in pediatric patients undergoing maxillofacial surgery with intraoperative maxillomandibular fixation was assessed. There was enough space for endotracheal tube placement in the retromolar region. The eruption of the first and second permanent molar teeth did not affect intubation. It was possible to achieve centric occlusion in 79 of 80 children with the endotracheal tube positioned in the retromolar space. Retromolar intubation was successfully accomplished in six pediatric patients undergoing maxillomandibular fixation and maxillofacial surgery. The retromolar space can be safely used for intubation in children when intraoperative maxillomandibular fixation, and simultaneous access to the nose and oral cavity are needed.

Increased red cell distribution width (RDW) is associated with poorer outcomes in various patient populations. We investigated the association between preoperative RDW and anaemia on 30-day postoperative mortality among elderly patients undergoing non-cardiac surgery. Medical records of 24,579 patients aged 65 and older who underwent surgery under anaesthesia between 1 January 2012 and 31 October 2016 were retrospectively analysed. Patients who died within 30 days had higher median RDW (15.0%) than those who were alive (13.4%). Based on multivariate logistic regression, in our cohort of elderly patients undergoing non-cardiac surgery, moderate/severe preoperative anaemia (aOR 1.61, p = 0.04) and high preoperative RDW levels in the 3rd quartile (>13.4% and ≤14.3%) and 4th quartile (>14.3%) were significantly associated with increased odds of 30-day mortality - (aOR 2.12, p = 0.02) and (aOR 2.85, p = 0.001) respectively, after adjusting for the effects of transfusion, surgical severity, priority of surgery, and comorbidities. Patients with high RDW, defined as >15.7% (90th centile), and preoperative anaemia have higher odds of 30-day mortality compared to patients with anaemia and normal RDW. Thus, preoperative RDW independently increases risk of 30-day postoperative mortality, and future risk stratification strategies should include RDW as a factor.

Background Intraoperative hypothermia is common in patients undergoing general anesthesia during arthroscopic hip surgery. In the present study, we assessed the effect of heating and humidifying the airway with a heated wire humidification circuit (HHC) to attenuate the decrease of core temperature and prevent hypothermia in patients undergoing arthroscopic hip surgery under general anesthesia. Methods Fifty-six patients scheduled for arthroscopic hip surgery were randomly assigned to either a control group using a breathing circuit connected with a heat and moisture exchanger (HME) (n = 28) or an HHC group using a heated wire humidification circuit (n = 28). The decrease in core temperature was measured from anesthetic induction and every 15 minutes thereafter using an esophageal stethoscope. Results Decrease in core temperature from anesthetic induction to 120 minutes after induction was lower in the HHC group (–0.60 ± 0.27℃) compared to the control group (–0.86 ± 0.29℃) (P = 0.001). However, there was no statistically significant difference in the incidence of intraoperative hypothermia or the incidence of shivering in the postanesthetic care unit. Conclusions The use of HHC may be considered as a method to attenuate intraoperative decrease in core temperature during arthroscopic hip surgery performed under general anesthesia and exceeding 2 hours in duration.

To determine the value of dissecting the recurrent laryngeal nerve during thyroid surgery with respect to preventing recurrent laryngeal nerve injury, we retrospectively analyzed clinical data from 5 344 patients undergoing thyroidectomy. Among these cases, 548 underwent dissection of the recurrent laryngeal nerve, while 4 796 did not. There were 12 cases of recurrent laryngeal nerve injury following recurrent laryngeal nerve dissection (injury rate of 2.2%) and 512 cases of recurrent laryngeal nerve injury in those not undergoing nerve dissection (injury rate of 10.7%). This difference remained statistically significant between the two groups in terms of type of thyroid disease, type of surgery, and number of surgeries. Among the 548 cases undergoing recurrent laryngeal nerve dissection, 128 developed anatomical variations of the recurrent laryngeal nerve (incidence rate of 23.4%), but no recurrent laryngeal nerve injury was found. In addition, the incidence of recurrent laryngeal nerve injury was significantly lower in patients with the inferior parathyroid gland and middle thyroid veins used as landmarks for locating the recurrent laryngeal nerve compared with those with the entry of the recurrent laryngeal nerve into the larynx as a landmark. These findings indicate that anatomical variations of the recurrent laryngeal nerve are common, and that dissecting the recurrent laryngeal nerve during thyroid surgery is an effective means of preventing nerve injury.

Background. Bariatric surgery is an important field of surgery. An important complication of bariatric surgery is dumping syndrome (DS). Aims. To evaluate the incidence of DS in patients undergoing bariatric surgery. Methods. 541 patients included from 5 nutrition and bariatric centers in France underwent either LSG or LRYGB. They were evaluated at 1 month (M1) and 6 months (M6) postoperatively by an interview and completion of a dumping syndrome questionnaire. Results. 268 patients underwent LSG (Group A) and 273 underwent LRYGB. From the LRYGB patients 229 had mechanical gastrojejunoanal anastomosis with 30 mm linear stapler (Group B) and 44 had manual (hand sewn) 15 mm gastrojejunal anastomosis (Group C). Overall incidence of DS was 8.5% at M1 and M6. In LSG group (Group A), only 4 patients (1.49%) reported episodes of DS at M1 and 3 (1.12%) at M6. In Group B, 41 patients (17.90%) reported episodes of DS at M1 and 43 (18.78%) at M6. Group C experienced one case (2.27%) of DS at M1 and none (0%) at M6. Conclusions. Patients undergoing LRYGB, especially with larger gastrojejunal anastomosis, are more prone to developing DS following surgery than patients undergoing LSG or LRYGB with calibrated manual anastomosis.

The perioperative management of chronic kidney disease (CKD) patients undergoing open-heart surgery is challenging. In this study, we evaluated the effects of tolvaptan in CKD patients after open-heart surgery. Between 2010 to 2015, 731 patients underwent open-heart surgery in our hospital. We consecutively selected 71 patients with stage IIIa-IV CKD and divided them into two groups. Those who received tolvaptan postoperatively were defined as the "Tolvaptan group" (n = 25) and those who did not were defined as the "Non-tolvaptan group" (n = 46). We compared the urine volume of postoperative days (POD) 1 and 2, the number of days to return to preoperative body weight (BW), and the change in the postoperative estimated glomerular filtration rate (eGFR). In the tolvaptan group, the urine volume was significantly larger (P = .04) and the duration to preoperative BW tended to be shorter. Overall, the postoperative change in the eGFR tended to be better in the tolvaptan group (P = .008). In particular, we found a significantly better trend in CKD stage IV (P = .04) patients and in the patients, whose cardiopulmonary bypass (CPB) time was longer than 120 min (P = .03). Tolvaptan can safely be used for CKD patients undergoing open-heart surgery and can provide a feasible urine volume without leading to a deterioration of their renal function.

Cardiac surgery induces an oxidative stress, which may lead to impairment of cardiac function. In this study, we aimed to measure the changes of oxidative and antioxidative status of patients undergoing coronary artery bypass surgery (CABG). We studied 79 patients who underwent CABG with and without cardiopulmonary bypass (CPB). Of the 79 patients, 39 had CPB and 40 did not. Blood samples were drawn before, during, and after the surgery. Antioxidant status was evaluated by measuring total antioxidant capacity (TAC), and oxidative status was evaluated by measuring total peroxide (TP) levels and oxidative stress index (OSI). TP and OSI levels increased, while TAC decreased progressively after the beginning of surgery, for all patients. There were negative correlations between TAC levels and aortic cross-clamping period and anastomosis time ( r = -0.553, p < 0.001 and r = -0.500, p < 0.001, respectively). In addition, there was a positive correlation between TAC and ejection fraction (r = 0.647, p < 0.001). During CABG, oxidant and OSI levels significantly increase and TAC significantly decreases. This situation is influenced by long CPB and anastomosis time, and also by low ventricular ejection fraction. We concluded that the patients who undergo CABG are exposed to potent oxidative stress that impairs their TAC. We speculate that supplementation with antioxidant vitamins such as vitamins C and E may be beneficial for patients undergoing CABG.

Peritoneal mesothelioma is a rare disease associated with poor prognosis. Acute abdomen as the first presentation is an extremely rare occurrence. We report an exceptional case of a patient who was found to have a jejunal perforation due to infiltration of peritoneal mesothelioma. A 62-year-old man was admitted with clinical signs of peritonitis. Computerized tomographic scans showed a mass distal to the ligament of Treitz, thickening of the mesentery and a small amount of ascites. Emergency laparotomy revealed a perforated tumor 15 cm distal to the ligament of Treitz and diffuse peritoneal disease. Segmental small bowel resection and suboptimal cytoreduction were performed. Histopathology and immunohistochemistry showed infiltration of malignant mesothelioma. During the postoperative period pleural mesothelioma was also diagnosed. Despite adjuvant chemotherapy, the patient died of disseminated progressive disease 7 months after surgery. Peritoneal mesothelioma is a rare malignancy with grim prognosis. Small bowel involvement is a poor prognostic indicator. Our case of a small bowel perforation due to direct infiltration by peritoneal mesothelioma appears to be the first reported in the English literature.

The natural history of advanced-stage epithelial ovarian cancer is one of clinical remission after surgery and platinum/taxane-based intravenous (IV) and/or intraperitoneal (IP) chemotherapy followed by early or late recurrence in the majority of patients. Prevention of progression and recurrence remains a major hurdle in the management of ovarian cancer. Recently, many investigators have evaluated the use of normothermic and hyperthermic intraoperative IP drug delivery as a management strategy. This is a narrative review of the current status of clinical trials of hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) in ovarian cancer and the future directions for this treatment strategy. The existing studies on HIPEC in patients with epithelial ovarian cancer are mostly retrospective in nature, are heterogeneous with regards to combined inclusion of primary and recurrent disease and lack unbiased data. Until data are available from evidence-based trials, it is reasonable to conclude that surgical cytoreduction and HIPEC is a rational and interesting, though still investigative, approach in the management of epithelial ovarian cancer, whose use should be employed within prospective clinical trials.

A 2-year-old neutered female Rottweiler diagnosed with an intradural extramedullary spinal cord tumor at T12-T13 was successfully treated with cytoreductive surgery followed by Cobalt 60 teletherapy. The dog was euthanised 5-and-a-half years later following diagnosis of an osteosarcoma involving the L1 and L2 vertebrae. Evidence of the initial tumor was not present at necropsy. The vertebral neoplasm fulfilled all of the accepted criteria for a radiation induced tumor. It was concluded that adjunctive irradiation should be considered for treatment of intradural extramedullary tumors of young dogs when total surgical resection is not possible. Although tumor induction is a rare late effect of radiation therapy, the risk of this occurrence should be considered when irradiating young animals. Radiation induced tumors in dogs have been associated with coarse fractionation schemes, or when large intraoperative doses have been administered. A lower dose per fraction, e.g., 3 Gy/fraction or less, is advisable when irradiating young dogs or any dog in which the life expectancy is 3-5 or more years after irradiation.

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.

At present, women are recommended to avoid pregnancy 12-18 months after bariatric surgery. Our aim in this study was to describe patterns of contraceptive use before and after gastric bypass in Sweden, and to describe the contraceptive counseling given preoperatively to women undergoing gastric bypass. In October 2012, a questionnaire was sent to 1000 Swedish women who all had undergone gastric bypass during 2010. The women had been included in the Scandinavian Obesity Surgery Register at time of surgery. The main outcome measures were patterns of use of contraception before and after bariatric surgery. The response rate was 57 %. The most commonly used contraceptive methods were intrauterine devices, 29 % preoperatively and 26 % postoperatively even though there was a postoperative switch from the copper intrauterine device to the levonorgestrel intrauterine system. Thirty percent did not use any contraceptive during the first 12 months after surgery. Sixty percent of the responders were aware of the recommendations to avoid pregnancy after surgery. Many women who undergo bariatric surgery are not using any contraceptive method despite the recommendation that they should avoid pregnancy for at least 12 months. There is a great need to improve contraceptive counseling for this growing group of women.

To test the hypothesis that cardiac-enriched micro-RNAs can serve as accurate biomarkers that reflect myocardial injury and to predict the postoperative course following pediatric cardiac surgery. Micro-RNAs have emerged as plasma biomarkers for many pathologic states. We aimed to quantify preoperative and postoperative plasma levels of cardiac-enriched micro-RNA-208a, -208b, and -499 in children undergoing cardiac surgery and to evaluate correlations between their levels, the extent of myocardial damage, and the postoperative clinical course. PICU. Thirty pediatric patients that underwent open heart surgery for the correction of congenital heart defects between January 2012 to July 2013. None. At 12 hours post surgery, the plasma levels of the micro-RNAs increased by 300- to 4,000-fold. At 24 hours, their levels decreased but remained significantly higher than before surgery. Micro-RNA levels were associated with troponin levels, longer cardiopulmonary bypass and aortic crossclamp times, maximal postoperative aspartate aminotransferase levels, and delayed hospital discharge. Circulating micro-RNA-208a, -208b, and -499 are detectable in the plasma of children undergoing cardiac surgery and may serve as novel biomarkers for monitoring and forecasting postoperative myocardial injury and recovery.

To determine postoperative pain in different types of ear, nose, and throat (ENT) surgery and their psychological preoperative predictors. Prospective cohort study. Academic hospital. A total of 217 patients undergoing ENT surgery. All ENT, neck, and salivary gland surgery. Postoperative pain and predictors for postoperative pain. Fifty percent of the patients undergoing surgery on the oral, pharyngeal, and laryngeal region and on the neck and salivary gland region had a visual analog scale score higher than 40 mm on day 1. In the patients who underwent oropharyngeal region operations the VAS score remained high on all 4 days. A VAS pain score higher than 40 mm was found in less than 30% of patients after endoscopic procedures and less than 20% after ear and nose surgery. After bivariate analysis, 6 variables--age, sex, preoperative pain, expected pain, short-term fear, and pain catastrophizing--had a predictive value. Multivariate analysis showed only preoperative pain, pain catastrophizing, and anatomical site of operation as independent predictors. Differences exist in the prevalence of unacceptable postoperative pain between ENT operations performed on different anatomical sites. A limited set of variables can be used to predict the occurrence of unacceptable postoperative pain after ENT surgery.

Menopausal symptoms are associated with a negative impact on the quality of life, leading women to seek medical treatment. Obesity has been linked to higher levels of menopausal symptoms such as hot flushes. This assessment will explore whether the prevalence and bother of hot flushes and vaginal dryness change from pre- to post-bariatric surgery among obese midlife women. This study is a longitudinal analysis of data from 69 women (ages 35-72 years) undergoing bariatric surgery with reported reproductive histories and menopausal symptoms at preoperative and 6-month postoperative visits. Prevalence of and degree of bother of hot flushes and vaginal dryness at pre- and post-surgery were compared using McNemar's test and Wilcoxon signed-rank test. The reported degree of bother of symptoms associated with hot flushes decreased from pre- to post-surgery (p < 0.01). There was no significant change in the prevalence of hot flushes or vaginal dryness in the overall study sample. The degree of bother of symptoms associated with hot flushes among midlife women may decrease after bariatric surgery. These results highlight important secondary gains, including less bothersome menopausal symptoms, for women who choose bariatric surgery for weight loss.

Cardioprotection during cardiac surgery

Coronary heart disease (CHD) is the leading cause of morbidity and mortality worldwide. For a large number of patients with CHD, coronary artery bypass graft (CABG) surgery remains the preferred strategy for coronary revascularization. Over the last 10 years, the number of high-risk patients undergoing CABG surgery has increased significantly, resulting in worse clinical outcomes in this patient group. This appears to be related to the ageing population, increased co-morbidities (such as diabetes, obesity, hypertension, stroke), concomitant valve disease, and advances in percutaneous coronary intervention which have resulted in patients with more complex coronary artery disease undergoing surgery. These high-risk patients are more susceptible to peri-operative myocardial injury and infarction (PMI), a major cause of which is acute global ischaemia/reperfusion injury arising from inadequate myocardial protection during CABG surgery. Therefore, novel therapeutic strategies are required to protect the heart in this high-risk patient group. In this article, we review the aetiology of PMI during CABG surgery, its diagnosis and clinical significance, and the endogenous and pharmacological therapeutic strategies available for preventing it. By improving cardioprotection during CABG surgery, we may be able to reduce PMI, preserve left ventricular systolic function, and reduce morbidity and mortality in these high-risk patients with CHD.

AIM: To evaluate the main factors associated with mortality in patients undergoing surgery for perforated peptic ulcer referred to an academic department of general surgery in a large southern Italian city. METHODS: One hundred and forty-nine consecutive patients (M:F ratio = 110:39, mean age 52 yrs, range 16-95) with peptic ulcer disease were investigated for clinical history (including age, sex, previous history of peptic ulcer, associated diseases, delayed abdominal surgery, ulcer site, operation type, shock on admission, postoperative general complications, and intra-abdominal and/or wound infections), serum analyses and radiological findings. RESULTS: The overall mortality rate was 4.0%. Among all factors, an age above 65 years, one or more associated diseases, delayed abdominal surgery, shock on admission, postoperative abdominal complications and/or wound infections, were significantly associated (χ2) with increased mortality in patients undergoing surgery (0.0001 < P < 0.03). CONCLUSION: Factors such as concomitant diseases, shock on admission, delayed surgery, and postoperative abdominal and wound infections are significantly associated with fatal outcomes and need careful evaluation within the general workup of patients admitted for perforated peptic ulcer.

To evaluate the changes of perioperative plasma concentrations of Aβ 1-40 and S-100β to determine the relationship with postoperative cognitive dysfunction in elderly patients undergoing oral and maxillofacial cancer surgeries. One hundred and fifteen patients aged at least 60 years undergoing oral and maxillofacial tumor resection were investigated between May 2014 to December 2014.Neuropsychological tests for detecting postoperative cognitive dysfunction(POCD) were performed one day before surgery and 7 days postoperatively. According to the results of neuropsychological tests on day 7, patients were divided into POCD group and non-POCD group.Plasma values of Aβ 1-40 and S-100β were determined with enzyme linked immunosorbent assay (ELISA) before anesthesia induction, 24 h and 7 days after surgery. The data were analyzed using SPSS 19.0 software package. According to the definition, POCD was present in 37 of 115 (32.3%) patients 1 week after surgery. Compared with pre-anesthesia, S-100β levels in POCD group were significantly increased (P<0.05); the level of Aβ 1-40 was significantly higher 24 h after surgery (P<0.05). Compared with non-POCD group, S-100β levels were significantly increased 24 h postoperatively (P<0.05); Aβ1-40 levels were significantly higher 24 h and 7 days postoperatively (P<0.05). POCD was present in 32.2% of patients on day 7 after oral and maxillofacial surgeries with general anesthesia. The increasing levels of Aβ 1-40 , S-100β may be associated with the occurence of POCD. Patients with long-lasting operation and high concentrations of Aβ 1-40 and S-100β after surgeries were at a higher risk of POCD. The clinical values of Aβ 1-40 and S-100 as predictive measurements of POCD after oral and maxillofacial cancer surgery appear to be reasonable.

Objectives To assess the recent prognostic trends in oesophageal adenocarcinoma and oesophageal squamous cell carcinoma undergoing resectional surgery and no such surgery. Additionally, risk factors for death were assessed in each of these patient groups. Design Cohort study. Setting A population-based, nationwide study in Sweden. Participants All patients diagnosed with oesophageal adenocarcinoma and oesophageal squamous cell carcinoma in Sweden from 1 January 1990 to 31 December 2013, with follow-up until 14 May 2017. Outcome measures Observed and relative (to the background population) 1-year, 3-year and 5-year survivals were analysed using life table method. Multivariable Cox regression provided HR with 95% CI for risk factors of death. Results Among 3794 patients with oesophageal adenocarcinoma and 4631 with oesophageal squamous cell carcinoma, 82% and 63% were men, respectively. From 1990–1994 to 2010–2013, the relative 5-year survival increased from 12% to 15% for oesophageal adenocarcinoma and from 9% to 12% for oesophageal squamous cell carcinoma. The corresponding survival following surgery increased from 27% to 45% in oesophageal adenocarcinoma and from 24% to 43% in oesophageal squamous cell carcinoma. In patients not undergoing surgery, the survival increased from 3% to 4% for oesophageal adenocarcinoma and from 3% to 6% for oesophageal squamous cell carcinoma. Women with oesophageal squamous cell carcinoma had better prognosis than men both following surgery (HR 0.71, 95% CI 0.61 to 0.83) and no surgery (HR 0.86, 95% CI 0.81 to 0.93). Conclusions The prognosis has improved over calendar time both in oesophageal adenocarcinoma and oesophageal squamous cell carcinoma in Sweden that did and did not undergo surgery. Women appear to have better prognosis in oesophageal squamous cell carcinoma than men, independent of treatment. PMID:29748347

Retrospective analysis of prospectively collected data. To create a data-driven triage system stratifying patients by likelihood of undergoing spinal surgery within one year of presentation. Low back pain (LBP) and radicular lower extremity (LE) symptoms are common musculoskeletal problems. There is currently no standard data-derived triage process based on information that can be obtained prior to the initial physician-patient encounter to direct patients to the optimal physician type. We analyzed patient-reported data from 8006 patients with a chief complaint of LBP and/or LE radicular symptoms who presented to surgeons at a large multidisciplinary spine center between September 1, 2005 and June 30, 2016. Univariate and multivariate analysis identified independent risk factors for undergoing spinal surgery within one year of initial visit. A model incorporating these risk factors was created using a random sample of 80% of the total patients in our cohort, and validated on the remaining 20%. The baseline one-year surgery rate within our cohort was 39% for all patients and 42% for patients with LE symptoms. Those identified as high likelihood by the center's existing triage process had a surgery rate of 45%. The new triage scoring system proposed in this study was able to identify a high likelihood group in which 58% underwent surgery, which is a 46% higher surgery rate than in non-triaged patients and a 29% improvement from our institution's existing triage system. The data-driven triage model and scoring system derived and validated in this study (Spine Surgery Likelihood model [SSL-11]), significantly improved existing processes in predicting the likelihood of undergoing spinal surgery within one year of initial presentation. This triage system will allow centers to more selectively screen for surgical candidates and more effectively direct patients to surgeons or non-operative spine specialists. 4.

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

We investigated the survival after laser-induced interstitial thermotherapy in 16 patients suffering from recurrent glioblastoma multiforme. The concept underlying the intervention is the cytoreduction of the tumor tissue by local thermocoagulation. All patients received standard chemotherapy (temozolomide). The median overall survival time after the first relapse was 9.4 months, corresponding to a median overall survival time after laser irradiation of 6.9 months. During the study, however, the median survival after laser coagulation increased to 11.2 months. This survival time is substantially longer than those reported for the natural history (<5 months) or after chemotherapy (temozolomide: 5.4-7.1 months). We conclude that cytoreduction by laser irradiation might be a promising option for patients suffering from recurrent glioblastoma multiforme. In addition, the data indicate the presence of a substantial learning curve. Future work should optimize the therapeutic regimen and evaluate this treatment approach in controlled clinical trials.

Retrospective database analysis. To investigate incidence, comorbidities, and impact on health care resources of Clostridium difficile infection after lumbar spine surgery. C. difficile colitis is reportedly increasing in hospitalized patients and can have a negative impact on patient outcomes. No data exist on estimates of C. difficile infection rates and its consequences on patient outcomes and health care resources among patients undergoing lumbar spine surgery. The Nationwide Inpatient Sample was examined from 2002 to 2011. Patients were included for study based on International Classification of Diseases, Ninth Revision, Clinical Modification, procedural codes for lumbar spine surgery for degenerative diagnoses. Baseline patient characteristics were determined and multivariable analyses assessed factors associated with increased incidence of C. difficile and risk of mortality. The incidence of C. difficile infection in patients undergoing lumbar spine surgery is 0.11%. At baseline, patients infected with C. difficile were significantly older (65.4 yr vs. 58.9 yr, P<0.0001) and more likely to have diabetes with chronic complications, neurological complications, congestive heart failure, pulmonary disorders, coagulopathy, and renal failure. Lumbar fusion (P=0.0001) and lumbar fusion revision (P=0.0003) were associated with increased odds of postoperative infection. Small hospital size was associated with decreased odds (odds ratio [OR], 0.5; P<0.001), whereas urban hospitals were associated with increased odds (OR, 2.14; P<0.14) of acquiring infection. Uninsured (OR, 1.62; P<0.0001) and patients with Medicaid (OR, 1.33; P<0.0001) were associated with higher odds of acquiring postoperative infection. C. difficile increased hospital length of stay by 8 days (P<0.0001), hospital charges by 2-fold (P<0.0001), and inpatient mortality to 4% from 0.11% (P<0.0001). C. difficile infection after lumbar spine surgery carries a 36.4-fold increase in mortality and costs approximately $10,658,646 per year to manage. These data suggest that great care should be taken to avoid C. difficile colitis in patients undergoing lumbar spine surgery because it is associated with longer hospital stays, greater overall costs, and increased inpatient mortality. 3.

Is neoadjuvant chemoradiation with dose-escalation and consolidation chemotherapy sufficient to increase surgery-free and distant metastases-free survival in baseline cT3 rectal cancer?

Patients with cT3 rectal cancer are less likely to develop complete response to neoadjuvant chemoradiation (nCRT) and still face significant risk for systemic relapse. In this setting, radiation (RT) dose-escalation and consolidation chemotherapy in "extended" nCRT regimens have been suggested to improve primary tumor response and decrease the risks of systemic recurrences. For these reasons we compared surgery-free and distant-metastases free survival among cT3 patients undergoing standard or extended nCRT. Patients with distal and non-metastatic T3 rectal cancer managed by nCRT were retrospectively reviewed. Patients undergoing standard CRT (50.4 Gy and 2 cycles of 5FU-based chemotherapy) were compared to those undergoing extended CRT (54 Gy and 6 cycles of 5FU-based chemotherapy). Patients were assessed for tumor response at 8-10 weeks. Patients with complete clinical response (cCR) underwent organ-preservation strategy (Watch & Wait). Patients were referred to salvage surgery in the event of local recurrence during follow-up. Cox's logistic regression was performed to identify independent features associated with improved surgery-free survival after cCR and distant-metastases-free survival. 155 patients underwent standard and 66 patients extended CRT. Patients undergoing extended CRT were more likely to harbor larger initial tumor size (p = 0.04), baseline nodal metastases (cN+; p < 0.001) and higher tumor location (p = 0.02). Cox-regression analysis revealed that the type of nCRT regimen was not independently associated with distinct surgery-free survival after cCR or distant-metastases-free survival (p > 0.05). Dose-escalation and consolidation chemotherapy are insufficient to increase long-term surgery-free survival among cT3 rectal cancer patients and provides no advantage in distant metastases-free survival.

Cardiac surgery is accompanied by an increase of oxidative stress, a significantly reduced antioxidant (AOX) capacity, postoperative inflammation, all of which may promote the development of organ dysfunction and an increase in mortality. Selenium is an essential co-factor of various antioxidant enzymes. We hypothesized a less pronounced decrease of circulating selenium levels in patients undergoing off-pump coronary artery bypass (OPCAB) surgery due to less intraoperative oxidative stress. In this prospective randomised, interventional trial, 40 patients scheduled for elective coronary artery bypass grafting were randomly assigned to undergo either on-pump or OPCAB-surgery, if both techniques were feasible for the single patient. Clinical data, myocardial damage assessed by myocard specific creatine kinase isoenzyme (CK-MB), circulating whole blood levels of selenium, oxidative stress assessed by asymmetric dimethylarginine (ADMA) levels, antioxidant capacity determined by glutathionperoxidase (GPx) levels and perioperative inflammation represented by interleukin-6 (IL-6) levels were measured at predefined perioperative time points. At end of surgery, both groups showed a comparable decrease of circulating selenium concentrations. Likewise, levels of oxidative stress and IL-6 were comparable in both groups. Selenium levels correlated with antioxidant capacity (GPx: r = 0.720; p<0.001) and showed a negative correlation to myocardial damage (CK-MB: r =  -0.571, p<0.001). Low postoperative selenium levels had a high predictive value for the occurrence of any postoperative complication. OPCAB surgery is not associated with less oxidative stress and a better preservation of the circulating selenium pool than on-pump surgery. Low postoperative selenium levels are predictive for the development of complications. ClinicalTrials.gov NCT01409057.

Studies in various surgical procedures have shown that transfusion of red blood cells (RBC) increases the risk of postoperative morbidity and mortality. Impact of blood transfusion in patients undergoing spine surgery is not well-described. We assessed the impact of intra and postoperative transfusion on postoperative morbidity and mortality in patients undergoing elective spine surgery. We used the American College of Surgeons' National Surgical Quality Improvement Program to identify a retrospective cohort of 36,901 adult patients who underwent elective spine surgery between 2006 and 2011. Patients who received intra or postoperative transfusion (n=3262) were matched to those who did not using propensity scores. Logistic regression predicted adverse postoperative outcomes. We conducted sensitivity analysis in a subset of patients in whom the number of intraoperatively transfused units of RBC or whole blood was known. Upon matching, preoperative hematocrit, length of surgery, and percentage of spinal fusion surgery were not significantly different between transfused and non-transfused patients. After matching, transfusion remained adversely associated with prolonged length of stay (LOS) in hospital (odds ratio [OR] 2.6, 95% confidence interval [CI] 2.3-2.9), postoperative complications (OR 1.6, 95% CI 1.4-1.9), and an increased 30 day return to operation room (OR 1.7, 95% CI 1.3-2.2). Transfusion of even one unit of blood intraoperatively was associated with prolonged LOS (OR 2.0, 95% CI 1.5-2.6) and minor complications (OR 2.4, 95% CI 1.3-4.3). Therefore, transfusion of RBC or whole blood, even a single unit, increased LOS and postoperative morbidity in patients undergoing elective spine surgery, independent of preoperative hematocrit level and patient comorbidities.

It is not known whether modern volatile anesthetics are associated with less mortality and postoperative pulmonary or other complications in patients undergoing general anesthesia for surgery. A systematic literature review was conducted for randomized controlled trials fulfilling following criteria: (1) population: adult patients undergoing general anesthesia for surgery; (2) intervention: patients receiving sevoflurane, desflurane, or isoflurane; (3) comparison: volatile anesthetics versus total IV anesthesia or volatile anesthetics; (4) reporting on: (a) mortality (primary outcome) and (b) postoperative pulmonary or other complications; (5) study design: randomized controlled trials. The authors pooled treatment effects following Peto odds ratio (OR) meta-analysis and network meta-analysis methods. Sixty-eight randomized controlled trials with 7,104 patients were retained for analysis. In cardiac surgery, volatile anesthetics were associated with reduced mortality (OR = 0.55; 95% CI, 0.35 to 0.85; P = 0.007), less pulmonary (OR = 0.71; 95% CI, 0.52 to 0.98; P = 0.038), and other complications (OR = 0.74; 95% CI, 0.58 to 0.95; P = 0.020). In noncardiac surgery, volatile anesthetics were not associated with reduced mortality (OR = 1.31; 95% CI, 0.83 to 2.05, P = 0.242) or lower incidences of pulmonary (OR = 0.67; 95% CI, 0.42 to 1.05; P = 0.081) and other complications (OR = 0.70; 95% CI, 0.46 to 1.05; P = 0.092). In cardiac, but not in noncardiac, surgery, when compared to total IV anesthesia, general anesthesia with volatile anesthetics was associated with major benefits in outcome, including reduced mortality, as well as lower incidence of pulmonary and other complications. Further studies are warranted to address the impact of volatile anesthetics on outcome in noncardiac surgery.

Graves' disease is a common cause of thyrotoxicosis. Treatment options include anti-thyroid medications or definitive therapy: thyroidectomy or radioactive iodine (I(131) ). Traditionally, I(131) has been the preferred definitive treatment for Graves' disease in New Zealand. Reports of concomitant thyroid cancer occurring in up to 17% of Graves' patients suggest surgery, if performed with low morbidity, may be the preferred option. The aim of this study was to determine the rate of thyroid cancer and surgical outcomes in a New Zealand cohort of patients undergoing thyroidectomy for Graves' disease. This study is a retrospective review of Waikato region patients undergoing thyroid surgery for Graves' disease during the 10-year period prior to 1 December 2011. A total of 833 patients underwent thyroid surgery. Of these, 117 were for Graves' disease. Total thyroidectomy was performed in 82, near-total in 33 and subtotal in 2 patients. Recurrent thyrotoxicosis developed in one subtotal patient requiring I(131) therapy. There were two cases of permanent hypoparathyroidism and one of permanent recurrent laryngeal nerve palsy. Eight patients (6.8%) had thyroid cancer detected, none of whom had overt nodal disease. Five were papillary microcarcinomas (one of which was multifocal), two were papillary carcinomas (11 mm and 15 mm) and one was a minimally invasive follicular carcinoma. Thyroid cancer was identified in approximately 7% of patients undergoing surgery for Graves' disease. A low complication rate (<2%) of permanent hypoparathyroidism and nerve injury (<1%) supports surgery being a safe alternative to I(131) especially for patients with young children, ophthalmopathy or compressive symptoms. © 2012 The Authors.

Inherited factor VII (FVII) deficiency is a rare coagulation disorder with variable haemorrhagic manifestations. In severely affected cases spontaneous haemarthroses leading to advanced arthropathy have been observed. Such cases may require surgery. Therapeutic options for bleeding prevention in FVII deficient patients undergoing surgery comprise various FVII preparations but the use of recombinant activated factor VII (rFVIIa) seems to be the treatment of choice. To present the outcome of orthopaedic surgery under haemostatic coverage of rFVIIa administered according to the locally established treatment regimen in five adult patients with FVII baseline plasma levels below 10 IU dL(-1). Two patients required total hip replacement (THR); three had various arthroscopic procedures. Recombinant activated factor VII was administered every 8 h on day of surgery (D0) followed by every 12-24 h for the subsequent 9-14 days, depending on the type of surgery. Factor VII plasma coagulation activity (FVII:C) was determined daily with no predefined therapeutic target levels. Doses of rFVIIa on D0 ranged from 18 to 37 μg kg(-1) b.w. and on the subsequent days--from 13 to 30 μg kg(-1) b.w. Total rFVIIa dose per procedure ranged from 16 to 37.5 mg, and the total number of doses per procedure was 16-31. None of our patients developed excessive bleeding including those in whom FVII:C trough levels returned nearly to the baseline level on the first post-op day. Preliminary results demonstrate that rFVIIa administered according to our treatment regimen is an effective and safe haemostatic agent for hypoproconvertinaemia patients undergoing orthopaedic surgery. © 2012 Blackwell Publishing Ltd.

Enhanced recovery after surgery (ERAS) programmes and laparoscopic techniques both provide short-term benefits to patients undergoing colorectal cancer surgery. ERAS protocol compliance may improve long-term survival in those undergoing open colorectal resection but as laparoscopic data has not been reported. Therefore, we aimed to investigate the impact of the combination of laparoscopy and ERAS management on 5-year overall survival. A dedicated prospectively populated colorectal cancer surgery database was reviewed. Patient inclusion criteria were biopsy-proven colorectal adenocarcinoma, undergoing elective surgery undertaken with curative intent. All patients were managed within an established ERAS programme and routinely followed up for 5 years. Overall survival was measured using the log-rank Kaplan-Meier method at 5 years. Eight hundred fifty-four patients met the inclusion criteria. Four hundred eighty-one (56%) cases were laparoscopic with 98 patients (20%) requiring conversion. There were no differences in patient or tumour demographics between the surgical groups. Median ERAS protocol compliance was 93% (range 53-100%). Five-year overall survival was superior in laparoscopic cases compared with that of converted and open surgery (78 vs 68 vs 70%, respectively, p < 0.007). An open approach (HR 1.55, 95%CI 1.16-2.06, p = 0.002) and delayed hospital discharge (> 7 days, HR 1.5, 95%CI 1.13-1.9, p = 0.003) were the only modifiable risk factors associated with poor survival. The use of a laparoscopic approach with enhanced recovery after surgery management appears to have long-term survival benefits following colorectal cancer resection.

Background Valve surgery for patients presenting with infective endocarditis (IE) complicated by stroke is thought to carry elevated risk of postoperative complications. Our aim is to compare outcomes of IE patients who undergo surgery early after diagnosis of septic cerebral emboli with patients without preoperative emboli. Methods All patients undergoing surgery for left-sided IE between 1996–2013 at our institution were reviewed. Patients undergoing surgery > 14 days after embolic stroke diagnosis (n=11) and those with purely hemorrhagic lesions were excluded from analysis (n=7). In total, 308 were included in the study and stratified according to the presence (STR, n=54) or absence of a preoperative septic cerebral embolus (NoSTR, n=254). Primary outcomes of interest were development of new postoperative stroke and 30-day mortality. Results Mean time to surgical intervention from stroke onset was 6.0 ± 4.1 days. S. aureus (39% STR vs. 21% NoSTR, p = 0.004) and annular abscess at surgery (52% STR vs. 27% NoSTR, p < 0.001) were more prevalent in STR patients. There was no significant difference in 30-day mortality (9.3% STR vs. 7.1% NoSTR, p = 0.57) or rate of new postoperative stroke [5 (9.4%) STR vs. 12 (4.7%) NoSTR, p = 0.19] between groups. Additionally, there was no difference in 10-year survival between groups (log rank p = 0.74). Conclusions Early surgical intervention in patients with IE complicated by preoperative septic cerebral emboli does not lead to significantly worse postoperative outcomes. Early surgery for IE following embolic stroke warrants consideration, particularly in patients with high-risk features such as S. aureus and/or annular abscess. PMID:26116483

Surgeons are increasingly confronted by patients on long-term low-dose acetylsalicylic acid (ASA). However, owing to a lack of evidence-based data, a widely accepted consensus on the perioperative management of these patients in the setting of non-cardiac surgery has not yet been reached. Primary objective was to evaluate the safety of continuous versus discontinuous use of ASA in the perioperative period in elective general or abdominal surgery. Fifty-two patients undergoing elective cholecystectomy, inguinal hernia repair or colonic/colorectal surgery were recruited to this pilot study. According to cardiological evaluation, non-high-risk patients who were on long-term treatment with low-dose ASA were eligible for inclusion. Patients were allocated randomly to continuous use of ASA or discontinuation of ASA intake for 5 days before until 5 days after surgery. The primary outcome was the incidence of major haemorrhagic and thromboembolic complications within 30 days after surgery. A total of 26 patients were allocated to each study group. One patient (3.8%) in the ASA continuation group required re-operation due to post-operative haemorrhage. In neither study group, further bleeding complications occurred. No clinically apparent thromboembolic events were reported in the ASA continuation and the ASA discontinuation group. Furthermore, there were no significant differences between both study groups in the secondary endpoints. Perioperative intake of ASA does not seem to influence the incidence of severe bleeding in non-high-risk patients undergoing elective general or abdominal surgery. Further, adequately powered trials are required to confirm the findings of this study.

The reported incidence of acute chest syndrome (ACS) in children with sickle cell disease (SCD) is 15% to 20%. Our current objective was to assess risk factors and morbidity associated with ACS. The authors reviewed the outcome of children with SCD undergoing abdominal surgery over a 10-year period. From 1991 to 2003, 60 children underwent laparoscopic cholecystectomy (LC; n = 29), laparoscopic splenectomy (LS; n = 28), or both (LB; n = 3). Mean age was 8.6 (0.7 to 20) years, and 35 (58%) were boys. Fifty-four (90%) had a preoperative hemoglobin greater than 10 g/dL, but only 22 (37%) received routine oxygen after surgery. No surgery was converted to an open procedure. Four children (6.6%), all of whom underwent either LS or LB, had ACS associated with an increased length of stay (7.4 +/- 2.4 days) but no mortality. Factors associated with the development of ACS were age (3.0 +/- 1.7 v 9.4 +/- 5.7 years; P =.03), weight (12.1 +/- 3.0 v 32.6 +/- 18.2 kg; P =.04), operative blood loss (3.2 +/- 0.5 v 1.4 +/- 1.2 mL/kg; P =.03), and final temperature in the operating room (OR; 36.2 +/- 0.4 v 37.6 +/- 0.4 degrees C; P =.01). ACS was not significantly related to duration of surgery, OR fluids, or oxygen usage. Younger children with greater blood and heat loss during surgery appear more prone to ACS. Splenectomy also seems to increase the risk of ACS. The authors' current incidence (6.6%) of ACS in children with SCD undergoing abdominal surgery is much lower than previously reported. This may be explained by the aggressive use of preoperative blood transfusion or more routine use of laparoscopy.

Background Gut barrier loss has been implicated as a critical event in the occurrence of postoperative complications. We aimed to study the development of gut barrier loss in patients undergoing major non-abdominal surgery. Methodology/Principal Findings Twenty consecutive children undergoing spinal fusion surgery were included. This kind of surgery is characterized by long operation time, significant blood loss, prolonged systemic hypotension, without directly leading to compromise of the intestines by intestinal manipulation or use of extracorporeal circulation. Blood was collected preoperatively, every two hours during surgery and 2, 4, 15 and 24 hours postoperatively. Gut mucosal barrier was assessed by plasma markers for enterocyte damage (I-FABP, I-BABP) and urinary presence of tight junction protein claudin-3. Intestinal mucosal perfusion was measured by gastric tonometry (PrCO2, Pr-aCO2-gap). Plasma concentration of I-FABP, I-BABP and urinary expression of claudin-3 increased rapidly and significantly after the onset of surgery in most children. Postoperatively, all markers decreased promptly towards baseline values together with normalisation of MAP. Plasma levels of I-FABP, I-BABP were significantly negatively correlated with MAP at ½ hour before blood sampling (−0.726 (p<0.001), −0.483 (P<0.001), respectively). Furthermore, circulating I-FABP correlated with gastric mucosal PrCO2, Pr-aCO2-gap measured at the same time points (0.553 (p = 0.040), 0.585 (p = 0.028), respectively). Conclusions/Significance This study shows the development of gut barrier loss in children undergoing major non-abdominal surgery, which is related to preceding hypotension and mesenterial hypoperfusion. These data shed new light on the potential role of peroperative circulatory perturbation and intestinal barrier loss. PMID:19088854

To examine whether the addition of narrow band imaging (NBI) to traditional white light imaging during laparoscopic surgery impacts pain and quality of life (QOL) at 3 and 6 months after surgery among women with suspected endometriosis and/or infertility. A randomized controlled trial (Canadian Task Force classification level I). The trial was conducted in 2 medical centers. From October 2011 to November 2013, 167 patients undergoing laparoscopic examination for suspected endometriosis and/or infertility were recruited. The analytic study sample includes 148 patients with pain and QOL outcome data. Patients were randomized in a 3:1 ratio to receive white light imaging followed by NBI (WL/NBI) or white light imaging only (WL/WL). Questionnaires were administered at baseline and at 3- and 6-month follow-up time points. Average and most severe pain at each time point were assessed using a 10-cm visual analog scale. QOL was measured using the Endometriosis Health Profile-30. Baseline characteristics were similar for the study groups. The WL/NBI and WL/WL groups had similar reductions in pain at 3 and 6 months. In addition, QOL improved similarly for both the WL/NBI and WL/WL groups at 3 and 6 months. Laparoscopic surgery for suspected endometriosis is associated with a reduction in pain and an improvement in QOL. The differences in pain reduction and QOL improvement, which are noted at 3 months and remain stable at 6 months after surgery, are similar for those undergoing surgery with WL/NBI compared with those undergoing surgery under traditional white light conditions.

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.

Evolving Indications for Tricuspid Valve Surgery

2010-01-01

Opinion statement More attention has been paid to the mitral valve (MV) than the tricuspid valve (TV), and this relative paucity of data has led to confusion regarding the timing of TV surgery. We review the American College of Cardiology/American Heart Association and European Society of Cardiology guidelines to identify areas of concordance (severe tricuspid regurgitation [TR] in a patient undergoing mitral valve surgery); discordance (less than severe TR but with markers for late TR recurrence such as pulmonary hypertension, a dilated TV annulus, atrial fibrillation, permanent transtricuspid pacing wires and others); and disagreement (surgery for primary TR). We provide our perspective from Northwestern University on these issues and where the guidelines are silent (TR in patients undergoing non-mitral valve operations). Finally, we review recent publications on the results of TV repair and replacement. Although there have been scant publications in the past, there have been more useful publications in recent years to guide our decision making. PMID:21063935

Despite the lack of efficacy data, robotic-assisted surgery has diffused rapidly into practice. Marketing to physicians, hospitals, and patients has been widespread, but how this marketing has contributed to the diffusion of the technology remains unknown. To examine the effect of regional hospital competition and hospital financial status on the use of robotic-assisted surgery for 5 commonly performed procedures. A cohort study of 221 637 patients who underwent radical prostatectomy, total nephrectomy, partial nephrectomy, hysterectomy, or oophorectomy at 1370 hospitals in the United States from January 1, 2010, to December 31, 2011, was conducted. The association between hospital competition, hospital financial status, and performance of robotic-assisted surgery was examined. The association between hospital competition was measured with the Herfindahl-Hirschman Index (HHI), hospital financial status was estimated as operating margin, and performance of robotic-assisted surgery was examined using multivariate mixed-effects regression models. We identified 221 637 patients who underwent one of the procedures of interest. The cohort included 30 345 patients who underwent radical prostatectomy; 20 802, total nephrectomy; 8060, partial nephrectomy; 134 985, hysterectomy; and 27 445, oophorectomy. Robotic-assisted operations were performed for 20 500 (67.6%) radical prostatectomies, 1405 (6.8%) total nephrectomies, 2759 (34.2%) partial nephrectomies, 14 047 (10.4%) hysterectomies, and 1782 (6.5%) oophorectomies. Use of robotic-assisted surgery increased for each procedure from January 2010 through December 2011. For all 5 operations, increased market competition (as measured by the HHI) was associated with increased use of robotic-assisted surgery. For prostatectomy, the risk ratios (95% CIs) for undergoing a robotic-assisted procedure were 2.20 (1.50-3.24) at hospitals in moderately competitive markets and 2.64 (1.84-3.78) for highly competitive markets compared with noncompetitive markets. For hysterectomy, patients at hospitals in moderately (3.75 [2.26-6.25]) and highly (5.30; [3.27-8.57]) competitive markets were more likely to undergo a robotic-assisted surgery. Increased hospital profitability was associated with use of robotic-assisted surgery only for partial nephrectomy in facilities with medium-high (1.67 [1.13-2.48]) and high (1.50 [0.98-2.29]) operating margins. With analysis limited to patients treated at a hospital that had performed robotic-assisted surgery, there was no longer an association between competition and use of robotic-assisted surgery. Patients undergoing surgery in a hospital in a competitive regional market were more likely to undergo a robotic-assisted procedure. These data imply that regional competition may influence a hospital's decision to acquire a surgical robot.

Most studies examining psychosocial changes after cosmetic surgery have short follow-up periods and therefore provide limited information about long-term effects of such surgery. Moreover, studies that identify whether preexisting patient characteristics are associated with poor psychosocial outcomes after cosmetic surgery are lacking. The current study provides information about both of these issues. Questionnaire data from 130 female Norwegian cosmetic surgery patients were obtained before and 5 years after surgery. The questionnaire consisted of measures on appearance satisfaction, self-esteem, psychological problems, and patients' evaluation of the outcome of surgery. Data from a representative sample of 838 Norwegian women, aged 22 to 55 years, were used for comparison purposes. Analyses revealed an improvement in both general appearance satisfaction and satisfaction with the body part operated on 5 years after surgery. A small increase in self-esteem was observed as well. High rates of preoperative psychological problems and low self-esteem were related to more negative changes in some of the psychosocial measures after surgery compared with patients with better psychological health. Furthermore, factors associated with the actual decision to undergo surgery were related to changes in psychological health and patients' evaluation of the outcome of surgery. This study indicates that cosmetic surgery has positive long-term effects on appearance-related variables. However, surgeons should be particularly aware of patients with psychological problems, as these may compromise patient satisfaction with the effects of cosmetic surgery. Factors affecting the decision itself to undergo cosmetic surgery may also be relevant for subsequent psychosocial outcomes. Therapeutic, II.

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

Surgical technique of en bloc pelvic resection for advanced ovarian cancer.

PubMed

Chang, Suk Joon; Bristow, Robert E

2015-04-01

The aim of this paper was to describe the operative details for en bloc removal of the adnexal tumor, uterus, pelvic peritoneum, and rectosigmoid colon with colorectal anastomosis in advanced epithelial ovarian cancer patients with widespread pelvic involvement. The patient presented with good performance status and huge pelvic tumor extensively infiltrating into adjacent pelvic organs and obliterating the cul-de-sac. The patient underwent en bloc pelvic resection as primary cytoreductive surgery. En bloc pelvic resection procedure is initiated by carrying a circumscribing peritoneal incision to include all pan-pelvic disease within this incision. After retroperitoneal pelvic dissection, the round ligaments and infundibulopelvic ligaments are divided. The ureters are dissected and mobilized from the peritoneum. After dissecting off the anterior pelvic peritoneum overlying the bladder with its tumor nodules, the bladder is mobilized caudally and the vesicovaginal space is developed. The uterine vessels are divided at the level of the ureters, and the paracervical tissues (or parametria) are divided. The proximal sigmoid colon is divided above the most proximal extent of gross tumor using a ligating and dividing stapling device. The sigmoid mesentery is ligated and divided including the superior rectal vessels. The pararectal and retrorectal spaces are further developed and dissected down to the level of the pelvic floor. The posterior dissection is progressed and moves to the right and then to the left of the rectum. The rectal pillars including the middle rectal vessels are ligated and divided. Hysterectomy is completed in a retrograde fashion. The distal rectum is divided using a linear stapler. The specimen is removed en bloc with the uterus, adnexa, pelvic peritoneum, rectosigmoid colon, and tumor masses leaving a macroscopically tumor-free pelvis. Colorectal anastomosis was completed using stapling device. En bloc pelvic resection was performed by total abdominal hysterectomy, bilateral salpingo-oophorectomy, pelvic peritonectomy, and rectosigmoid colectomy with colorectal anastomosis using a stapling device. Complete clearance of pelvic disease leaving no gross residual disease was possible using en bloc pelvic resection. En bloc pelvic resection is effective for achieving maximal cytoreduction with the elimination of the pelvic disease in advanced primary ovarian cancer patients with extensive pelvic organ involvement.

Surgery is a major stress factor that activates several inflammatory and catabolic pathways in man. An appropriate nutritional status allows the body to react properly to this stressor and recover in a faster and more efficient manner. On the other hand, malnutrition is related to a worse surgery outcome and to a higher prevalence of comorbidities and mortality. The aims of this study were to evaluate the nutritional status of patients undergoing major surgery and investigate the potential correlation between malnutrition and surgical outcomes. Mini Nutritional Assessment (MNA) and global clinical examination (including biochemical parameters and comorbidities existence) were undertaken in 50 consecutive patients undergoing major surgery. Patients' clinical conditions were re-evaluated at 3 and 6 days after surgery, recording biochemical parameters and systemic and/or wound-related complications. A compromised nutritional status was present in more than half (54%) of patients (malnutrition in 10% and risk of malnutrition in 44% of patients, respectively). Females were slightly more at risk of malnutrition (48% vs. 41%, p=NS, females vs. males) and clearly malnourished (14% vs. 7%, p<0.05, females vs. males). Age was an independent risk factor for malnutrition and within the elders' group (> 80 years old) 16.70% of patients was diagnosed with malnutrition and 58.3% was at risk of malnutrition. Systemic complications were registered in all patients both at 3 and 6 days after surgery. However, well-nourished and at-risk of malnutrition patients had earlier complications that only partially resolved within six days after the operation. Malnourished patients showed fewer complications at the 3rd post-surgery follow-up day but had a worse outcome six days after surgery. Older age and but not female sex are independent risk factors for malnutrition development in patients undergoing major surgery. More interestingly, more than half of patients with an impaired nutritional status presented a less appropriated stress response to surgery. These data suggest that nutritional status assessment may be important to recognize patients at potential risk of surgical complications and that early nutritional interventions must be promptly arranged.

Parents feel fear and anxiety before surgery is performed on their child, and those feelings could obstruct their preparation for the surgery. Preoperative information could relieve those feelings. To determine the preoperative information needs of parents of children undergoing elective surgery. A study was conducted on the parents of children who underwent elective surgery. Demographic data of parents were recorded. Preoperative information received or would like to have received was assessed in terms of contents, methods, opportunity, place and informant. Descriptive statistics were used. Thirteen hundred parents were surveyed. More than 80% of them want preoperative information about anaesthesia, surgery, preoperative fasting, drugs and anaesthetic complications, monitoring, intravenous line management, pain treatment, postoperative feeding, anxiety control, hospitalisation room, recovery room, and entertainment in recovery room. Most want to be informed verbally, one to two weeks in advance and not on the same day of surgery. The informant should be the surgeon and in his office. In addition, they want information through leaflets, videos and simulation workshops, or guided tours. Parents need complete preoperative information about anesthesia, surgery and postoperative care, received verbally and in advance. Copyright © 2015 Sociedad Chilena de Pediatría.

Background According to current guidelines, pancreatic cancer patients should be strictly selected for surgery, either palliative or resective. Methods Population-based study, including all patients undergoing surgery for pancreatic cancer in Italy between 2010 and 2012. Hospitals were divided into five volume groups (quintiles), to search for differences among volume categories. Results There were 544 hospitals performing 10 936 pancreatic cancer operations. The probability of undergoing palliative/explorative surgery was inversely related to volume, being 24.4% in very high-volume hospitals and 62.5% in very low-volume centres (adjusted OR 5.175). Contrarily, the resection rate in patients without metastases decreased from 86.9% to 46.1% (adjusted OR 7.429). As for resections, the mortality of non-resective surgery was inversely related to volume (p < 0.001). Surprisingly, mortality of non-resective surgery was higher than that for resections (8.2% vs. 6.7%; p < 0.01). Approximately 9% of all resections were performed on patients with distant metastases, irrespective of hospital volume group. The excess cost for the National Health System from surgery overuse was estimated at 12.5 million euro. Discussion. Discrepancies between guidelines on pancreatic cancer treatment and surgical practice were observed. An overuse of surgery was detected, with serious clinical and economic consequences.

This retrospective comparative study aims to explore the time courses of serum myoglobin (Mb) changes, and summarize our experience in treating patients with hypermyoglobinemia after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC).This study covered 60 patients with peritoneal carcinomatosis treated with CRS + HIPEC as the study group, and another 25 cancer patients treated with conventional extensive surgery without HIPEC as the control group from February to October 2016. In the study group, patients with postoperative hypermyoglobinemia were on a comprehensive treatment regimen consisting intravenous injection of sodium bicarbonate solution according to the Mb level. In the control group, patients were recorded and treated with the same regimen except for special sodium bicarbonate solution. The preoperative and postoperative serum Mb, blood urine nitrogen (BUN), and creatinine (Cr) levels were evaluated.There were no significantly difference between the 2 groups in serum Mb, BUN, and Cr levels before surgery. Postoperative serum Mb levels were elevated in both groups and significantly higher on postoperative 0 to 2 days (P < .05) in the study group than the control group. The peak value of serum Mb levels (426.65 ± 108.386 μg/L) occurred on the surgery day. The serum Mb change rate was much bigger in the study group than the control group. Serum BUN levels in both groups revealed a slow increase during the early postoperative period and were significantly lower in the study group than the control group on days 1 and 2. The serum Cr levels were similar and stable between the 2 groups after surgery. The serum Cr change rates changed synchronously with same tendency in both groups, and on postoperative day 1 the increase rate was bigger in the control group than the study group.Hypermyoglobinemia is a common and prominent lab abnormality after CRS + HIPEC, and serum Mb levels could be an early and sensitive indicator for dramatic disturbances in the internal milieu after CRS + HIPEC. Adequate treatment with sodium bicarbonate could accelerate the reduction in serum Mb levels and reduce the risk for major organ damages.

Accumulating data suggest more aggressive surgery in patients with malignant glioma to improve outcome. However, extended surgery may increase morbidity. The randomized Phase III 5-aminolevulinic acid (ALA) study investigated 5-ALA-induced fluorescence as a tool for improving resections. An interim analysis demonstrated more frequent complete resections with longer progression-free survival (PFS). However, marginal differences were found regarding neurological deterioration and the frequency of additional therapies. Presently, the authors focus on the latter aspects in the final study population, and attempt to determine how safety might be affected by cytoreductive surgery. Patients with malignant gliomas were randomized for fluorescence-guided (ALA group) or conventional white light (WL) (WL group) microsurgery. The final intent-to-treat population consisted of 176 patients in the ALA and 173 in the WL group. Primary efficacy variables were contrast-enhancing tumor on early MR imaging and 6-month PFS. Among secondary outcome measures, the National Institutes of Health Stroke Scale (NIH-SS) score and the Karnofsky Performance Scale (KPS) score were used for assessing neurological function. More frequent complete resections and improved PFS were confirmed, with higher median residual tumor volumes in the WL group (0.5 vs 0 cm(3), p = 0.001). Patients in the ALA group had more frequent deterioration on the NIH-SS at 48 hours. Patients at risk were those with deficits unresponsive to steroids. No differences were found in the KPS score. Regarding outcome, a combined end point of risks and neurological deficits was attempted, which demonstrated results in patients in the ALA group to be superior to those in participants in the WL group. Interestingly, the cumulative incidence of repeat surgery was significantly reduced in ALA patients. When stratified by completeness of resection, patients with incomplete resections were quicker to deteriorate neurologically (p = 0.0036). Extended resections performed using a tool such as 5-ALA-derived tumor fluorescence, carries the risk of temporary impairment of neurological function. However, risks are higher in patients with deficits unresponsive to steroids.

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 investigate anesthesia management in patients undergoing right lung surgery after a previous left upper lobectomy (LUL) that may require special precautions since angulation of the left bronchus can hamper correct placement of a left-sided double-lumen tube (DLT), and one-lung ventilation (OLV) depending solely on the left lower lobe may lead to inadequate oxygenation. A retrospective data analysis. Single university hospital. Patients underwent right lung surgery after previous LUL. None. Anesthesia management was investigated in 18 patients who underwent right lung surgery following LUL. All intubation procedures were performed under bronchoscopic guidance to prevent airway trauma. OLV could be achieved with a left-sided DLT in 12 patients, while tubes other than this were required in 6 patients, including a right-sided DLT (n = 3) and a bronchial blocker (n = 3). The presence or absence of remarkable bronchial angulation, characterized by a combination of a wide (>140°) angle between the trachea and left main bronchus and a narrow (<100°) angle between the left main and lower bronchi critically affected tube selections. The minimum SpO2 during OLV was 90.9±4.1%. In 2 patients, intermittent bilateral ventilation was required to treat desaturation. In all the patients, the scheduled surgery could be completed. Extent of left bronchial angulations had a critical impact on whether or not a left-sided DLT could be used in patients undergoing right lung surgery after LUL. Copyright © 2016 Elsevier Inc.

Objective The risk of urinary tract infection (UTI) among women undergoing elective gynecologic surgery where a catheter is placed is high: 10 to 64% following catheter removal. We conducted the first randomized, double-blind, placebo-controlled trial of the therapeutic efficacy of cranberry juice capsules in preventing UTI post surgery. Study Design We recruited patients from a single hospital between August 2011 and January 2013. Eligible participants were undergoing elective gynecologic surgery that did not involve a fistula repair or vaginal mesh removal. 160 patients were randomized and received two cranberry juice capsules two times a day, equivalent to two 8-ounce servings of cranberry juice, for 6 weeks after surgery, or matching placebo. The primary endpoint was the proportion of participants who experienced clinically-diagnosed and treated UTI with or without positive urine culture. Kaplan-Meier plots and logrank tests compared the two treatment groups. Results The occurrence of UTI was significantly lower in the cranberry treatment group compared to the placebo group (15/80 (19%) versus 30/80 (38%); OR=0.38; 95% CI: 0.19, 0.79; p=0.008). After adjustment for known confounders, including frequency of intermittent self-catheterization in the post- operative period, the protective effects of cranberry remained (OR=0.42; 95% CI: 0.18, 0.94). There were no treatment differences in the incidence of adverse events; including gastrointestinal upset (56% vs. 61% for cranberry vs. placebo). Conclusions Among women undergoing elective benign gynecologic surgery involving urinary catheterization, use of cranberry extract tablets during the postoperative period reduced the rate of UTI by half.

Patients subjected to haemodilution during surgery are at increased risk of bleeding. We hypothesised that, in the acquired dilutional coagulopathy, insufficient haemostasis is due to either insufficient thrombin generation or insufficient fibrin clot formation. In tissue factor-activated plasmas from patients with coagulation deficiency, we measured time curves of thrombin generation and fibrin clot formation (thromboelastography). Investigated were in study A: 10 patients treated with vitamin K antagonist and five healthy subjects; in study B: 30 patients undergoing cardiopulmonary bypass (CPB) surgery and infused with on average 2,000 ml crystalloids and colloids (no major bleeding); in study C: 58 patients undergoing major general surgery, and transfused with >5,000 ml crystalloids, colloids and red cell concentrates, who experienced major bleeding and were post-transfused with fresh frozen plasma. The treatment with vitamin K antagonist led to a progressive reduction in thrombin generation but not fibrin clot formation. In CPB patients, plasma factor levels post-surgery were 53-60% of normal. This was accompanied by moderate reduction in both haemostatic processes. In plasmas from patients undergoing major surgery, factor levels were 38-41% of normal, and these levels increased after plasma transfusion. Taking preset thresholds for normal thrombin generation and fibrin clot formation, at least one of these processes was low in 88-93% of the patients with (persistent) bleeding, but only in 40-53% of the patients without bleeding. In conclusion, the ability of thrombin generation and fibrin clot formation is independently reduced in acquired dilutional coagulopathy, while minimal levels of both are required for adequate haemostasis.

The aim of this study was to explore the effect of electroacupuncture (EA) on immune function in patients undergoing supratentorial craniotomy. We also examined whether point specificity in EA was present. The study involved 29 patients undergoing craniotomy. The patients were divided into three groups: a control (C, n=10), an EA (A, n=9) and a sham acupoints group (S, n=10). Blood samples were collected at the following time points: before anesthesia (T0), 4 h after the induction of anesthesia (T1), 1 day post-surgery (T2) and 2 days post-surgery (T3) to determine the levels of tumor necrosis factor-α (TNF-α), interleukin-8 (IL-8), interleukin-10 (IL-10), immunoglobulin M (IgM), IgA and IgG. Data were analyzed using SPSS 13.0 software. When comparing the levels of cytokines following surgery, we observed that the peripheral blood IL-8 levels in groups A and S were increased significantly compared with those of group C at 1 and 2 days after surgery. When comparing immunoglobulin levels after surgery, we established that the peripheral blood IgA levels in group C had decreased significantly compared to those of group A and group S 4 h after induction of anesthesia and 1 day after surgery. However, there was no significant difference between group A and group S. Compared with simple general anesthesia, acupuncture combined with anesthesia partially reduces immune suppression in the perioperative periods under the same conditions as the simple general anesthesia. Point specificity in EA was not present. PMID:24137250

Pulmonary embolism (PE) is a life-threatening condition common after major surgery. Although the high incidence (0.3-30%) and mortality rate (16.9-31%) of PE in patients undergoing major surgical procedures is apparent from findings of contemporary observational studies, there is a lack of a summary and meta-analysis data on the epidemiology of postoperative PE in this same regard. Hence, we propose to conduct the first systematic review to summarise existing data on the global incidence, determinants and case fatality rate of PE following major surgery. Electronic databases including MEDLINE, EMBASE, SCOPUS, WHO global health library (including LILACS), Web of Science and Google scholar from inception to April 30, 2017, will be searched for cohort studies reporting on the incidence, determinants and case fatality rate of PE occurring after major surgery. Data from grey literature will also be assessed. Two investigators will independently perform study selection and data extraction. Included studies will be evaluated for risk of bias. Appropriate meta-analytic methods will be used to pool incidence and case fatality rate estimates from studies with identical features, globally and by subgroups of major surgical procedures. Random-effects and risk ratio with 95% confidence interval will be used to summarise determinants and predictors of mortality of PE in patients undergoing major surgery. This systematic review and meta-analysis will provide the most up-to-date epidemiology of PE in patients undergoing major surgery to inform health authorities and identify further research topics based on the remaining knowledge gaps.

Little is known about patient satisfaction and disability after brachial plexus surgery. Would patients undergo the procedure again, if they knew the current result beforehand? How do they rate their result and their disability? Of 319 plexus patients who had undergone surgery between 1995 and 2005, 199 received a 65-item questionnaire. Measurement instruments included a new plexus-specific outcome questionnaire (Ulm Questionnaire) with categories of satisfaction, functionality, pain, comorbidities, and work; and the disability of the arm, shoulder, and hand questionnaire (DASH; scale, 0-100). Of 99 returned questionnaires, 70 were returned in a useful form for evaluation. The results of patients with C5-C6 lesions (21 of 70) are as follows: 90% (19 of 21) would undergo surgery again, 95% (20 of 21) were satisfied with the result, and 86% (18 of 21) subjectively improved. The mean DASH score was 41 (standard deviation [SD], 24). The results of patients with C5-C7 lesions (6 of 70) are as follows: 50% (3 of 6) were satisfied and would undergo surgery again, and 67% (4 of 6) improved. The mean DASH score was 46 (SD, 13). The results of patients with C5-T1 lesions (43 of 70) are as follows: 67% (29 of 43) would undergo surgery again, 81% (35 of 42) were satisfied, and 74% (32 of 43) reported improvement. The mean DASH score was 58 (SD, 26). The overall mean DASH score was 52 (SD, 26). Pain since the injury was prevalent in 86% of patients (60 of 70), back pain in 53%, and depression/anxiety in 21%. Fifty-two percent of those who worked before their injury (27 of 53 patients) remained unemployed or incapacitated for work. Forty-five percent of previous workers (24 of 53) returned to their former occupation. Occupational retraining was successful for 70% of patients (16 of 23). The mean duration until return to work was 9 months overall and 5 months for those who returned to their previous occupation. Eighty-seven percent of patients were satisfied with the results and 83% would undergo the procedure again. Despite a high satisfaction rate, patients remained considerably disabled, and half of the previous workers did not return to work. Occupational retraining is effective.

Background Transpulmonary thermodilution allows the measurement of cardiac index for high risk surgical patients. Oncologic patients often have a central venous access (port-a-catheter) for chronic treatment. The validity of the measurement by a port-a-catheter of the absolute cardiac index and the detection of changes in cardiac index induced by fluid challenge are unknown. Methods We conducted a monocentric prospective study. 27 patients were enrolled. 250 ml colloid volume expansions for fluid challenge were performed during ovarian cytoreductive surgery. The volume expansion-induced changes in cardiac index measured by transpulmonary thermodilution by a central venous access (CIcvc) and by a port-a-catheter (CIport) were recorded. Results 23 patients were analyzed with 123 pairs of measurements. Using a Bland and Altman for repeated measurements, the bias (lower and upper limits of agreement) between CIport and CIcvc was 0.14 (−0.59 to 0.88) L/min/m2. The percentage error was 22%. The concordance between the changes in CIport and CIcvc observed during volume expansion was 92% with an r = 0.7 (with exclusion zone). No complications (included sepsis) were observed during the follow up period. Conclusions The transpulmonary thermodilution by a port-a-catheter is reliable for absolute values estimation of cardiac index and for measurement of the variation after fluid challenge.

Background Surgery can cure a significant percentage of ovarian carcinoma confined to the pelvis. Nevertheless, there is still a 10–50% recurrence rate. We administered paclitaxel/carboplatin as adjuvant treatment in early-stage ovarian carcinoma. Methods Patients with stages Ia or Ib, Grade 2 or 3 and Ic to IIb (any grade) were included. Patients were treated with 4 cycles of Paclitaxel 175 mg/m2 and Carboplatin [area under the curve (AUC) 6 (Calvert Formula)] every 3 weeks. Results Sixty-nine patients with no residual disease following cytoreductive surgery and minimal or modified surgical staging were included in this analysis. Grade 3 or 4 neutropenia occured in 29.9% of patients, while neutropenic fever was reported in 4.5%. Neurotoxicity (all Grade 1 or 2) was reported in 50% of cases. Median follow-up was 62 months. 5-year overall survival (OS) and relapse-free survival (RFS) were: 87% (95% confidence intervals [CI]: 78–96) and 79% (95% CI: 69–89), respectively. Significantly fewer patients with stages Ic-IIb and tumor grade 2 or 3 achieved a 5-year RFS than patients with only one of these two factors (73% vs 92%, p = 0.03). Conclusion Paclitaxel/Carboplatin chemotherapy is a safe and effective adjuvant treatment in early-stage ovarian carcinoma. Patients with stages Ic-IIb and tumor grade 2 or 3 may benefit from more extensive treatment. PMID:16999858

Desmoplastic small round cell tumor (DSRCT) is a rare mesenchymal malignancy. We describe our experience with treating DSRCT at a large sarcoma referral center. A retrospective chart review was performed on DSRCT patients referred to our institution (1998-2014). Pathology specimens were reviewed to confirm the diagnosis. Clinical and imaging were extracted and summarized with descriptive statistics. Univariate analysis was performed to evaluate the association between patient, tumor, and treatment variables and overall survival (OS). In this study cohort of 20 patients, median age at presentation was 29 y (range 18-43) and 90% were male. Fifty-five percent presented with metastasis. Patients underwent chemotherapy (n = 20), radiation therapy (n = 3), and cytoreductive surgery (CRS) (n = 5). Median OS was 22 m (interquartile range: 12-28 m). Five-year OS rate was 20%. Extra-abdominal metastasis was associated with a higher hazard ratio (HR) of mortality (HR: 3.1, 95% C.I. 1.0-9.4, p = 0.04), while CRS improved OS (HR: 0.1, 95% C.I. 0.03-0.7, p = 0.02). Despite aggressive treatment, less than half of the patients were dead of DSRCT within 2 years of presentation. Although a select group of patients who underwent CRS had improved OS, novel treatments are urgently needed.

The objective of this retrospective study was to evaluate the influence of neoadjuvant systemic chemotherapy on patients with colorectal carcinomatosis before a curative procedure. Peritoneal carcinomatosis (PC) from colorectal cancer may be treated with a curative intent by cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). The role of perioperative systemic chemotherapy for this particular metastatic disease remains unclear. One hundred twenty patients with PC from colorectal cancer were consecutively treated by 131 procedures combining CRS with HIPEC. The response to neoadjuvant systemic chemotherapy was assessed on data from previous explorative surgery and/or radiological imaging. Ninety patients (75%) were treated with neoadjuvant systemic chemotherapy in whom 32 (36%) were considered to have responded, 19 (21%) had stable disease, and 19 (21%) developed diseases progression. Response could not be evaluated in 20 patients (22%). On univariate analysis, the use of neoadjuvant systemic chemotherapy had a significant positive prognostic influence (P = 0.042). On multivariate analysis, the completeness of CRS and the use of adjuvant systemic chemotherapy were the only significant prognostic factors (P < 0.001 and P = 0.049, respectively). Response to neoadjuvant systemic chemotherapy had no significant prognostic impact with median survival of 31.4 months in patients showing disease progression. In patients with PC from colorectal cancer without extraperitoneal metastases, failure of neoadjuvant systemic chemotherapy should not constitute an absolute contraindication to a curative procedure combining CRS and HIPEC.

Objective To determine the value of apparent diffusion coefficient (ADC) histogram parameters for the prediction of individual survival in patients undergoing surgery for recurrent glioblastoma (GBM) in a retrospective cohort study. Methods Thirty-one patients who underwent surgery for first recurrence of a known GBM between 2008 and 2012 were included. The following parameters were collected: age, sex, enhancing tumor size, mean ADC, median ADC, ADC skewness, ADC kurtosis and fifth percentile of the ADC histogram, initial progression free survival (PFS), extent of second resection and further adjuvant treatment. The association of these parameters with survival and PFS after second surgery was analyzed using log-rank test and Cox regression. Results Using log-rank test, ADC histogram skewness of the enhancing tumor was significantly associated with both survival (p = 0.001) and PFS after second surgery (p = 0.005). Further parameters associated with prolonged survival after second surgery were: gross total resection at second surgery (p = 0.026), tumor size (0.040) and third surgery (p = 0.003). In the multivariate Cox analysis, ADC histogram skewness was shown to be an independent prognostic factor for survival after second surgery. Conclusion ADC histogram skewness of the enhancing lesion, enhancing lesion size, third surgery, as well as gross total resection have been shown to be associated with survival following the second surgery. ADC histogram skewness was an independent prognostic factor for survival in the multivariate analysis.

To evaluate the outcome of fertility-sparing surgery among young women with early-stage clear cell carcinoma of the ovary. In a retrospective study, data were reviewed for patients aged 45years or younger who had FIGO stage I clear cell carcinoma of the ovary and had attended one institution in South Korea between December 1999 and December 2009. Outcomes were compared between women undergoing fertility-sparing surgery, defined as preservation of the uterus and at least one adnexa, and those undergoing radical surgery. Overall, 47 patients were included (22 underwent fertility-sparing surgery, 25 radical surgery). After a median follow-up of 72months (range 8-175), 5 (23%) patients who underwent fertility-sparing surgery and 5 (20%) in the radical surgery group had recurrent disease (P=0.820). The mean time to recurrence was 19months after fertility-sparing surgery versus 20months after radical surgery (P=0.935). The anatomical location of recurrence did not differ. There was no difference in 5-year disease-free survival (77% vs 84%; P=0.849) or 5-year overall survival (91% vs 88%; P=0.480). Fertility-sparing surgery was found to be a safe alternative for young women with FIGO stage I clear cell carcinoma of the ovary who wish to preserve fertility.

According to current recommendations, patients could benefit from tricuspid valve (TV) annuloplasty at the time mitral valve (MV) surgery if tricuspid regurgitation is severe or if tricuspid annulus (TA) dilatation is present. Therefore, an accurate pre-operative echocardiographic study is mandatory for left but also for right cardiac structures. Aims of this study are to assess right atrial (RA), right ventricular (RV) and TA geometry and function in patients undergoing MV repair without or with TV annuloplasty. We studied 103 patients undergoing MV surgery without (G1: 54 cases) or with (G2: 49 cases) concomitant TV annuloplasty and 40 healthy subjects (NL) as controls. RA, RV and TA were evaluated by three-dimensional (3D) transthoracic echocardiography. Comparing the pathological to the NL group, TA parameters and 3D right chamber volumes were significantly larger. RA and RV ejection fraction and TA% reduction were lower in pathological versus NL, and in G2 versus G1. In pathological patients, TA area positively correlated to systolic pulmonary pressure and negatively with RV and RA ejection fraction. Patients undergoing MV surgery and TV annuloplasty had an increased TA dimensions and a more advanced remodeling of right heart chambers probably reflecting an advanced stage of the disease.

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

Epidemiological, demographic, and economic analyses: measurement of the value of trichiasis surgery in The Gambia.

Untreated trichiasis can lead to corneal opacity. Surgery to prevent the eyelashes from rubbing against the cornea is available, but many individuals with trichiasis never undergo the operation. This study estimates the cost of illness of untreated trichiasis and the willingness to pay for surgery and compares them with the actual cost of providing surgery. The cost of illness estimate is based on trichiasis patient demographics. Data on the implicit price of obtaining surgery and surgical utilization in a matched pair randomized trial are used to infer individual willingness to pay for trichiasis surgery. Patients in the study paid nothing out-of-pocket for surgery; the price of obtaining surgery is the value of the individual's time needed for travel and surgery plus the price of public transportation. The cost of producing surgery was calculated from project records. All monetary figures are reported in 1998 US dollars. The average cost of untreated trichiasis, or the net present value of life-time lost economic productivity, was $89. Individuals facing a lower cost were more likely to undergo an operation; the inferred average willingness to pay was $1.43 (SD 0.244). Surgery cost $6.13 to provide, including $0.86 for transportation to the village. Whether the value of trichiasis surgery exceeds the cost in The Gambia depends on how the value is measured. Individuals are willing to use only limited resources to obtain surgery even though lifetime economic productivity may increase substantially. All three economic measures can be used to inform policy.

Tranexamic acid for reducing mortality in emergency and urgent surgery.

PubMed

Perel, Pablo; Ker, Katharine; Morales Uribe, Carlos Hernando; Roberts, Ian

2013-01-31

Emergency or urgent surgery, which can be defined as surgery which must be done promptly to save life, limb, or functional capacity, is associated with a high risk of bleeding and death. Antifibrinolytic agents, such as tranexamic acid, inhibit blood clot breakdown (fibrinolysis) and can reduce perioperative bleeding. Tranexamic acid has been shown to reduce the need for a blood transfusion in adult patients undergoing elective surgery but its effects in patients undergoing emergency or urgent surgery is unclear.   To assess the effects of tranexamic acid on mortality, blood transfusion and thromboembolic events in adults undergoing emergency or urgent surgery. We searched the following electronic databases: the Cochrane Injuries Group's Specialised Register (22 August 2012); Cochrane Central Register of Controlled Trials (2012, issue 8 of 12); MEDLINE (Ovid SP) 1950 to August Week 2, 2012; PubMed 1 June 2012 to 22 August 2012; EMBASE (Ovid SP) 1980 to 2012 Week 33; ISI Web of Science: Conference Proceedings Citation Index-Science (CPCI-S) 1990 to 22 August 2012; ISI Web of Science: Science Citation Index Expanded (SCI-EXPANDED) 1970 to 22 August 2012. We also searched online trial registers on 22 August 2012 to identify unpublished studies. Randomised controlled trials comparing tranexamic acid with no tranexamic acid or placebo in adults undergoing emergency or urgent surgery. Two authors examined titles, abstracts and keywords of citations from the electronic databases for eligibility and extracted data for analysis and risk of bias assessment. Outcome measures of interest were mortality, receipt of a blood transfusion, units of blood transfused, reoperation, seizures and thromboembolic events (myocardial infarction, stroke, deep vein thrombosis and pulmonary embolism). We identified five trials involving 372 people that met the inclusion criteria. Three trials (260 patients) contributed data to the analyses. The effect of tranexamic acid on mortality (RR 1.01; 95% CI 0.14 to 7.3) is uncertain. However, tranexamic acid reduces the probability of receiving a blood transfusion by 30% although the estimate is imprecise (RR 0.70; 95% CI 0.52 to 0.94). The effect on deep venous thrombosis (RR 2.29; 95% CI 0.68 to 7.66), and stroke (RR 2.79; 95% CI 0.12 to 67.10) is uncertain. There were no events of pulmonary embolism or myocardial infarction. None of the trials reported units of blood transfused, reoperation, or seizure outcomes. There is evidence that tranexamic acid reduces blood transfusion in patients undergoing emergency or urgent surgery. There is a need for a large pragmatic clinical trial to assess the effects of routine use of tranexamic acid on mortality in a heterogeneous group of urgent and emergency surgical patients.

Medical therapy is widely used for managing benign prostatic hyperplasia (BPH) and has made an impact on the profile of patients who ultimately undergo surgery. This changing profile may impact outcomes of surgery and associated complications. To assess the impact of medical management, we evaluated the profile of patients who had surgery for BPH at our institution. A retrospective chart-review was performed of patient demographics, indications for surgery, preoperative comorbid conditions and postoperative course in patients who underwent surgery for BPH over a 5-year period. The data were analysed for demographic trends in comparison with historical cohorts. A total of 327 patients underwent surgery for BPH between 2008 and 2012. Their mean age was 66.4 years, the mean prostate gland weight was 59.2 g and the mean duration of symptoms was 35.3 months; 34% had a prostate gland weight of >60 g; 1 59 (48.6%) patients had an absolute indication for surgery; 139 (42.5%) of these were catheterized and 6.1% of patients presented with azotaemia or upper tract changes without urinary retention. In comparison with historical cohorts, more patients are undergoing surgery for absolute indications including retention of urine and hydroureteronephrosis. However, the patients are younger, they have fewer comorbid conditions and have a similar rate of complications after the procedure.

Objective: To compare the diagnostic accuracy of multi-slice computed tomography (MSCT) angiography with conventional angiography in patients undergoing major noncoronary cardiac surgeries. Materials and Methods: We studied fifty major noncoronary cardiac surgery patients scheduled for invasive coronary angiography, 29 (58%) female and 21 (42%) male. Inclusion criteria of the study were age of the patients ≥40 years, having low or intermediate probability of coronary artery disease (CAD), left ventricular ejection fraction (LVEF) >35%, and patient giving informed consent for undergoing MSCT and conventional coronary angiography. The patients with LVEF <35%, high pretest probability of CAD, and hemodynamically unstable were excluded from the study. Results: The diagnostic accuracy of CT coronary angiography was evaluated regarding true positive, true negative values. The overall sensitivity and specificity of CT angiography technique was 100% (95% confidence interval [CI]: 39.76%–100%) and 91.30% (95% CI: 79.21%–97.58%). The positive (50%; 95% CI: 15.70%–84.30%) and negative predictive values (100%; 95% CI: 91.59%–100%) of CT angiography were also fairly high in these patients. Conclusion: Our study suggests that this non-invasive technique may improve perioperative risk stratification in patients undegoing non-cardiac surgery. PMID:27867455

Background The gut microbiome is altered in Crohn’s disease. Although individual taxa have been correlated with post-operative clinical course, global trends in microbial diversity have not been described in this context. Methods We collected mucosal biopsies from the terminal ileum and ascending colon during surgery and post-operative colonoscopy in 6 Crohn’s patients undergoing ileocolic resection (and 40 additional Crohn’s and healthy control patients undergoing either surgery or colonoscopy). Using next-generation sequencing technology, we profiled the gut microbiota in order to identify changes associated with remission or recurrence of inflammation. Results We performed 16S ribosomal profiling using 101 base-pair single-end sequencing on the Illumina GAIIx platform with deep coverage, at an average depth of 1.3 million high quality reads per sample. At the time of surgery, Crohn’s patients who would remain in remission were more similar to controls and more species-rich than Crohn’s patients with subsequent recurrence. Patients remaining in remission also exhibited greater stability of the microbiota through time. Conclusions These observations permitted an association of gut microbial profiles with probability of recurrence in this limited single-center study. These results suggest that profiling the gut microbiota may be useful in guiding treatment of Crohn’s patients undergoing surgery. PMID:23964800

One-year mortality is vital for elderly oncologic patients undergoing surgery. Recent studies have demonstrated that sarcopenia can predict outcomes after major abdominal surgeries, but the association of sarcopenia and 1-year mortality has never been investigated in a prospective study. We conducted a prospective study of elderly patients (≥65 years) who underwent curative gastrectomy for gastric cancer from July 2014 to July 2015. Sarcopenia was determined by the measurements of muscle mass, handgrip strength, and gait speed. Univariate and multivariate analyses were used to identify the risk factors associated with 1-year mortality. A total of 173 patients were included, in which 52 (30.1 %) patients were identified as having sarcopenia. Twenty-four (13.9 %) patients died within 1 year of surgery. Multivariate analysis showed that sarcopenia was an independent risk factor for 1-year mortality. Area under the receiver operating characteristic curve demonstrated an increased predictive power for 1-year mortality with the inclusion of sarcopenia, from 0.835 to 0.868. Solely low muscle mass was not predictive of 1-year mortality in the multivariate analysis. Sarcopenia is predictive of 1-year mortality in elderly patients undergoing gastric cancer surgery. The measurement of muscle function is important for sarcopenia as a preoperative assessment tool.

After anterior cruciate ligament (ACL) reconstruction, 63% to 87% of high school athletes return to competition. Although physical and psychological factors are known contributors for failure to return to play, little attention has been paid to effect of academic grade level. Our purpose was to determine the influence of effect of academic grade level on return to competitive play. The primary hypothesis is that high school seniors who undergo ACL reconstruction or knee arthroscopy will be less likely to return to competitive play at 1 year than those in grades 9 to 11. We retrospectively reviewed high school athletes who injured their knee during competitive athletic activity and underwent arthroscopic knee surgery, including ACL reconstruction. We included those 14 to 18 years old at time of surgery and analyzed records for grade level, sporting activity, surgery details, and date of return to play. The definition of return to competitive play was return to same preinjury sport within 1 year of surgery and the sport had to be organized. Our study group included 225 patients that underwent an ACL reconstruction and 74 had knee arthroscopy. Athletes undergoing ACL reconstructions were less likely to return to preinjury sport within 1 year than those undergoing knee arthroscopy (P=0.0163). Seniors were significantly less likely to return to play at 1 year than athletes in grades 9 to 11 after both ACL reconstruction (P<0.0001) and knee arthroscopy (P=0.0335). Although return to competitive play rates remained fairly constant within grades 9 to 11, a precipitous decline by 28.9% and 29.4% in return to play rates occurred in the ACL reconstruction and knee arthroscopy groups, respectively, between the junior and senior years of high school. Although return to competition rates were lower for high school athletes undergoing ACL reconstruction than those undergoing knee arthroscopy, both had declines in return when the surgery occurs during their senior season. These data are useful when interpreting return to play rates. Future studies would benefit from further defining this relationship, or at least, noting the number of "senior" athletes studied.

There has been considerable concern expressed about the outcomes achieved in Independent Sector Treatment Centres (ISTCs) introduced in England since 2003. Our aim was to compare the case-mix and patients' reported outcomes of surgery in ISTCs and in NHS providers. Prospective cohort study of 769 patients treated in six ISTCs and 1895 treated in 20 NHS providers (acute hospitals and treatment centres) in England during 2006-07. Participants underwent one of three day surgery procedures (inguinal hernia repair, varicose vein surgery, cataract extraction) or hip or knee replacement. Change in patient-reported health status and health related quality of life (measured using a disease-specific and a generic (EQ-5D) instrument) was assessed either 3-months (day surgery) or 6-months (hip/knee) after surgery. In addition patient-reported post-operative complications and an overall assessment of success of surgery were collected. Outcome measures were adjusted (using multivariable regression) for patient characteristics (disease severity, duration of symptoms, age, sex, socioeconomic status, general health, previous similar surgery, comorbidity). Post-operative response rates varied by procedure (73%-88%) and were similar for those treated in ISTCs and NHS facilities. Patients treated in ISTCs were healthier, were less likely to have any comorbidity and, for those undergoing cataract surgery or joint replacement, their primary condition was less severe. Those undergoing hernia repair or joint replacement were less likely to have had similar surgery before. When adjustment was made for pre-operative characteristics, patients undergoing cataract surgery or hip replacement in ISTCs achieved a slightly greater improvement in functional status and quality of life than those treated in NHS facilities, while the opposite was true of patients undergoing hernia repair. No significant differences were found for the two other procedures. Patients treated in ISTCs were less likely to report post-operative problems than those treated in NHS facilities for cataract surgery (Adjusted Odds Ratio 0.35; 95% CI 0.17-0.70), hernia repair (0.42; 0.28-0.63) and knee replacement (0.44; 0.28-0.69). Most patients described the result of their operation as excellent, very good or good, regardless of where they were treated. The case-mix of patients treated in ISTCs differs from that in NHS providers, in line with the intention of the contracts. Caution is needed in interpreting the observation that patients treated in ISTCs reported slightly better outcomes as very few ISTCs participated, case-mix adjustment might have been insufficient, and patients' reports might have been biased as they were more likely to be satisfied with the way they were treated.

Methadone is frequently administered to adults experiencing anesthesia and receiving pain treatment. Methadone pharmacokinetics in adults are well characterized, including the perioperative period. Methadone is also used in children. There is, however, no information on methadone pharmacokinetics in children of any age. The purpose of this investigation was to determine the pharmacokinetics of intravenous methadone in children undergoing surgery. Perioperative opioid-sparing effects were also assessed. Eligible subjects were children 5-18 yr undergoing general anesthesia and surgery, with an anticipated postoperative inpatient stay exceeding 3 days. Three groups of 10 to 11 patients each received intravenous methadone hydrochloride after anesthetic induction in ascending dose groups of 0.1, 0.2, and 0.3 mg/kg (up to 20 mg). Anesthetic care was not otherwise changed. Venous blood was obtained for 4 days, for stereoselective determination of methadone and metabolites. Pain assessments were made each morning. Daily and total opioid consumption was determined. Perioperative opioid consumption and pain was determined in a second cohort, which was matched to age, sex, race, ethnicity, surgical procedure, and length of stay, but not receiving methadone. The final methadone study cohort was 31 adolescents (14 ± 2 yr, range 10-18) undergoing major spine surgery for a diagnosis of scoliosis. Methadone pharmacokinetics were linear over the dose range 0.1-0.3 mg/kg. Disposition was stereoselective. Methadone administration did not dose-dependently affect postoperative pain scores, and did not dose-dependently decrease daily or total postoperative opioid consumption in spinal fusion patients. Methadone enantiomer disposition in adolescents undergoing surgery was similar to that in healthy adults.

Objective To systematically review the effects of preoperative and postoperative resistance exercise training on the recovery of physical function in patients undergoing abdominal surgery for cancer. Data sources A systematic review of English articles using Medline, Physiotherapy Evidence Database, CINAHL and the Cochrane Library electronic databases was undertaken. Eligibility criteria for selecting studies Studies were included if they used a randomised, quasi-randomised or controlled trial study design and compared the effects of a muscle-strengthening exercise intervention (±other therapy) with a comparative non-exercise group; involved adult participants (≥18 years) who had elected to undergo abdominal surgery for cancer; and used muscle strength, physical function, self-reported functional ability, range of motion and/or a performance-based test as an outcome measure. Results Following screening of titles and abstracts of the 588 publications retrieved from the initial search, 24 studies met the inclusion criteria and were accessed for review of the full-text version of the article, and 2 eligible studies met the inclusion criteria and were included in the review. One exercise programme was undertaken preoperatively and the other postoperatively, until discharge from hospital. The exercise interventions of the included studies were performed for five and eight sessions, respectively. There were no differences between groups in either study. Conclusion The only two studies designed to determine whether preoperative or postoperative resistance muscle-strengthening exercise programmes improved or negatively affected physical function outcomes in patients undergoing abdominal surgery for cancer provide inconclusive results.

The hospital experience can bring about a range of negative emotions for children. The literature clearly states that children who are prepared for surgery recover faster and have fewer negative effects. Pre-admission programmes seek to prepare children (and their parents) for surgery. This paper describes in detail how a pre-admission programme was established for children and their families who were scheduled for day case surgery.

Fluid strategies may impact on patient outcomes in major elective surgery. We aimed to study the effectiveness and cost-effectiveness of pre-operative fluid loading in high-risk surgical patients undergoing major elective surgery. This was a pragmatic, non-blinded, multi-centre, randomised, controlled trial. We sought to recruit 128 consecutive high-risk surgical patients undergoing major abdominal surgery. The patients underwent pre-operative fluid loading with 25 ml/kg of Ringer's solution in the six hours before surgery. The control group had no pre-operative fluid loading. The primary outcome was the number of hospital days after surgery with cost-effectiveness as a secondary outcome. A total of 111 patients were recruited within the study time frame in agreement with the funder. The median pre-operative fluid loading volume was 1,875 ml (IQR 1,375 to 2,025) in the fluid group compared to 0 (IQR 0 to 0) in controls with days in hospital after surgery 12.2 (SD 11.5) days compared to 17.4 (SD 20.0) and an adjusted mean difference of 5.5 days (median 2.2 days; 95% CI -0.44 to 11.44; P = 0.07). There was a reduction in adverse events in the fluid intervention group (P = 0.048) and no increase in fluid based complications. The intervention was less costly and more effective (adjusted average cost saving: £2,047; adjusted average gain in benefit: 0.0431 quality adjusted life year (QALY)) and has a high probability of being cost-effective. Pre-operative intravenous fluid loading leads to a non-significant reduction in hospital length of stay after high-risk major surgery and is likely to be cost-effective. Confirmatory work is required to determine whether these effects are reproducible, and to confirm whether this simple intervention could allow more cost-effective delivery of care.

We aimed to document the anesthetic management and metabolic, hemodynamic, and clinical outcomes of liver-graft recipients who subsequently undergo nontransplant surgical procedures. We retrospectively analyzed the data of 96 liver-graft recipients who underwent 144 nontransplant surgeries between October 1998 and April 2016 at Başkent University Hospital. The median patient age at the time of nontransplant surgery was 32 years, and 35% were female (n = 33). The median time between transplant and nontransplant surgery was 1231 days. The most frequent types of nontransplant surgery were abdominal (22%), orthopedic (16%), and urologic (13%). Seventy patients had an American Society of Anesthesiologists status of 2 (49%); the status was 3 in 71 patients (49%) and 4 in 3 patients (2%). Of the 144 procedures, 23 were emergent (16%) and 48% were abdominal. General anesthesia was used in 69%, regional anesthesia in 19%, and sedoanalgesia in 11%. Twenty-five patients required intraoperative blood-product transfusion (17%). Intraoperative hemodynamic instability developed in 17% of patients, and hypoxemia developed in 2%. Eleven patients remained intubated at the end of surgery (8%). Of the 144 procedures, 19 (13%) required transfer to the intensive care unit, 108 (75%) transferred to the ward, and the remaining 17 (12%) were discharged on the same day. Eight patients developed respiratory failure (6%), 7 had renal dysfunction (5%), 4 had coagulation abnormalities (3%), and 10 had infectious complications (7%) in the early postoperative period. The median hospital stay was 4 days, and 5 patients (4%) developed rejection during hospitalization. Five patients died of respiratory or infectious complications (4%). Most liver-graft recipients who undergo nontransplant surgery are given general anesthesia, transferred to the ward after the procedure, and discharged without major complications. We suggest that orthotopic liver transplant recipients may undergo nontransplant surgery without any postoperative graft dysfunction.

To examine whether untreated sleep apnoea is associated with prolonged Intensive Care Unit (ICU) stay and increased frequency of postoperative ICU complications, in patients undergoing major cardiac surgery. Adult patients, undergoing elective coronary artery bypass grafting with or without cardiac valve surgery, between March 2013 and July 2014, were considered. We excluded patients participating in other interventional studies, those who had a tracheostomy before surgery, required emergency surgery or were due to be admitted on the day of surgery. Patients underwent inpatient overnight oximetry on the night prior to their surgery to assess for the presence of sleep apnoea. Since oximetry alone cannot differentiate obstructive from central apnoea, the results are reported as sleep apnoea which was diagnosed in patients with an arterial oxygen desaturation index (ODI) ≥ 5/h. The primary outcome measure was length of stay (LoS) in ICU in days. The secondary outcome was a composite measure of postoperative complications in ICU. Multivariate models were developed to assess associations between ODI and the primary and secondary outcome measures, adjusting for preselected predictor variables, relative to primary and secondary outcomes. There was no significant association between ODI and ICU LoS, HR 1.0, 95% CI 0.99-1.02; p = 0.12. However we did find a significant association between ODI and postoperative complications in the ICU, OR = 1.1; 95% CI 1.02-1.17; p = 0.014. The probability of developing complications rose with higher ODI, reflecting sleep apnoea severity. Acknowledging the limitations of this prospective study, untreated sleep apnoea did not predict an increased length of stay in ICU but we do report an association with postoperative complications in patients undergoing major cardiac surgery.
