What did we catch? Predictors of infection after tissue expander-based breast reconstruction in a safety-net system.

BACKGROUND: Infection is a common complication following tissue expander (TE)-based breast reconstruction. Few studies have examined risk factors specifically in the unique populations encountered at safety-net hospitals. The purpose of this study was to identify predictors of TE infection at Harris Health safety-net hospitals, which serve the third most populous county in the United States. METHODS: A retrospective review was performed to evaluate women over the age of 18 years who underwent TE placement at two safety-net hospitals from October 2015 to November 2022. Demographic information, medical history, operative details, and postoperative course were recorded for each individual TE. The primary outcome was TE infection, for which univariate and multivariate analysis was conducted. The secondary outcome was the time to onset of TE infection, for which a Kaplan-Meier analysis was undertaken. RESULTS: There were 279 patients, totaling 372 breasts, meeting the inclusion criteria. The TE infection rate was 23%. Increased body mass index (BMI), diabetes, use of acellular dermal matrix (ADM), and prolonged surgical drain use were all significantly associated with TE infection in univariate and multivariate analysis. Similarly, BMI ≥30 kg/m2, diabetes, and ADM use were also associated with earlier onset of TE infection. CONCLUSIONS: This study demonstrated similar TE infection rates at our safety-net hospitals compared with previously reported literature. To optimize the quality of care for patients in safety-net institutions, these risk factors must be addressed in the context of the unique challenges encountered in these settings.

Strategic Approaches to Intraflap Anastomosis: Navigating Conjoined DIEP Flap Reconstruction-A Comprehensive Roadmap.

Background: For patients desiring autologous breast reconstruction without adequate abdominal tissue volume, the deep inferior epigastric perforator (DIEP) flap may be stacked or combined with other flaps for bilateral reconstruction. Various combinations of anastomoses have been described in the literature. We sought to describe a framework for intraflap anastomoses. Methods: A retrospective review of 17 patients who underwent conjoined DIEP flaps with intraflap anastomoses with a single surgeon was performed. Patient demographics, comorbidities, operative details, and complications were reviewed. A framework scheme was developed for the type of intraflap anastomosis performed. Results: Between 2016 and 2020, 17 patients underwent conjoined DIEP flaps for unilateral breast reconstruction. Fourteen patients had delayed reconstruction. Eleven patients underwent an intraflap anastomosis in which a medial perforator on the left hemiabdomen flap was anastomosed with a distal lateral row perforator in the right hemiabdomen flap (type A). Four patients underwent an intraflap anastomosis in which a left lateral perforator was anastomosed to a right distal lateral row perforator (type B). Two patients underwent an intraflap anastomosis in which the left superficial inferior epigastric vessel was anastomosed to a right lateral row perforator (type C). Complications included reoperation (11.8%), partial flap loss (5.9%), seroma (23.5%), and hematoma (11.8%). Conclusions: We report a detailed framework for intraflap anastomoses of conjoined DIEP flap reconstruction including superficial inferior epigastric artery/superficial inferior epigastric vessel options. Knowledge of this comprehensive framework will allow surgeons to identify the type of intraflap anastomoses required for the anatomy they encounter and will standardize reporting of surgical technique in the literature.

Pyoderma gangrenosum after deep inferior epigastric perforator flap: How prompt diagnosis and treatment can avoid surgical debridement and further morbidity.

Pyoderma gangrenosum (PG) is a skin disorder characterized by painful, enlarging necrotic ulcers with bluish borders surrounded by advancing zones of erythema. The key histologic feature is neutrophilic infiltration of the superficial and deep layers of the dermis and the absence of microorganisms. Although rare and associated with autoimmune diseases such as rheumatoid arthritis, ulcerative colitis and Crohn's disease, the diagnosis is commonly missed at presentation and patients are often treated for infection with antibiotics and surgical debridement. We present a case of PG in a 51 year-old woman after a deep inferior epigastric perforator (DIEP) flap for breast reconstruction who was promptly diagnosed and treated with steroids with appropriate response. Our case highlights the importance of rapid diagnosis and treatment of this disease to avoid incorrect management including surgical debridement, which can exacerbate the disease and increase its morbidity.

Distal pancreatectomy outcomes: Perspectives from a community-based teaching institution.

BACKGROUNDS/AIMS: Distal pancreatic resections are intricate operations with potential for significant morbidity; there is controversy surrounding the appropriate setting regarding surgeon/hospital volume. We report our distal pancreatectomy experience from a community-based teaching hospital. METHODS: This study includes all patients who underwent laparoscopic distal pancreatectomy (LDP) and open distal pancreatectomy (ODP) for benign and malignant lesions between June 2004 and October 2017. Both groups were compared for perioperative characteristics, parenchymal resection technique, and outcomes. RESULTS: 138 patients underwent distal pancreatectomy during this time. The distribution of LDP and ODP was 68 and 70 respectively. Operative time (146 vs. 174 min), blood loss (139 vs. 395 ml) and mean length of stay (4.8 vs. 8.0 days) were significantly lower in the laparoscopic group. The 30-day Clavien Grade 2/3 morbidity rate was 13.7% (19/138) and the incidence of Grade B/C pancreatic fistula was 6.5% (9/138), with no difference between ODP and LDP. 30-day mortality was 0.7% (1/138). 61/138 resections had a malignancy on final pathology. ODP mean tumor diameter was greater (6.4 cm vs. 2.9 cm), but there was no significant difference in the mean number of harvested nodes (8.6 vs. 7.4). The cost of hospitalization, including readmissions and surgery was significantly lower for LDP ($7558 vs. $11610). CONCLUSIONS: This series of distal pancreatectomies indicates a shorter hospital stay, less operative blood loss and reduced cost in the LDP group, and comparable morbidity and oncologic outcomes between LDP and ODP. It highlights the feasibility and safety of these complex surgeries in a community setting.

Disparities in the management and prophylaxis of surgical site infection and pancreatic fistula after pancreatoduodenectomy.

BACKGROUND: Pancreatoduodenectomy (PD) carries a high morbidity. Over time, pancreatic surgeons have altered their perioperative management in efforts to reduce morbidity rates, thereby creating major technical and management variations. We aim to evaluate the practice patterns of hepato-pancreato-biliary (HPB) surgeons across multiple regions worldwide. METHODS: Between May and August 2015, an anonymous 25-item survey questionnaire was electronically distributed to the International Hepato-Pancreato-Biliary Association members regarding practice patterns and perioperative care of patients undergoing PD. Responses were analyzed based on three variables: geographical region, institution type and volume status. RESULTS: Among 285 participants, the majority were high-volume surgeons (80.4%) at academic institutions (56.1%) from the United States (34.7%), Europe (28.1%) and Asia (14.3%). North American surgeons are more likely to limit prophylactic antibiotic within 24 h postoperatively (P < 0.001), whereas European surgeons more often culture bile intraoperatively (P = 0.024). There are significant variations between different institution types and HPB surgeons based on case volume. Very-high volume surgeons (>50 cases/year) are more likely to routinely culture intraoperative bile (64% vs. 33.3-37.5%) and close incision with subcuticular sutures (42.5% vs. 15.3-25.9%). CONCLUSIONS: Our survey demonstrated significant heterogeneity in perioperative management between HPB surgeons across different regions worldwide. Further studies are warranted to assess the impact of these variations on outcomes of patients undergoing PD. Efforts should be directed towards standardization of perioperative management of PD.

Are general surgery residents adequately prepared for hepatopancreatobiliary fellowships? A questionnaire-based study.

BACKGROUND: The present study was conducted to assess the preparedness of hepatopancreatobiliary (HPB) fellows upon entering fellowship, identify challenges encountered by HPB fellows during the initial part of their HPB training, and identify potential solutions to these challenges that can be applied during residency training. METHODS: A questionnaire was distributed to all HPB fellows in accredited HPB fellowship programmes in two consecutive academic years (n = 42). Reponses were then analysed. RESULTS: A total of 19 (45%) fellows responded. Prior to their fellowship, 10 (53%) were in surgical residency and the rest were in other surgical fellowships or surgical practice. Thirteen (68%) were graduates of university-based residency programmes. All fellows felt comfortable in performing basic laparoscopic procedures independently at the completion of residency and less comfortable in performing advanced laparoscopy. Eight (42%) fellows cited a combination of inadequate case volume and lack of autonomy during residency as the reasons for this lack of comfort. Thirteen (68%) identified inadequate preoperative workup and management as their biggest fear upon entering practice after general surgery training. A total of 17 (89%) fellows felt they were adequately prepared to enter HPB fellowship. Extra rotations in transplant, vascular or minimally invasive surgery were believed to be most helpful in preparing general surgery residents pursing HPB fellowships. CONCLUSIONS: Overall, HPB fellows felt themselves to be adequately prepared for fellowship. Advanced laparoscopic procedures and the perioperative management of complex patients are two of the challenges facing HPB fellows. General surgery residents who plan to pursue an HPB fellowship may benefit from spending extra rotations on certain subspecialties. Focus on perioperative workup and management should be an integral part of residency and fellowship training.

Total laparoscopic removal of accessory gallbladder: A case report and review of literature.

Accessory gallbladder is a rare congenital anomaly occurring in 1 in 4000 births, that is not associated with any specific symptoms. Usually this cannot be diagnosed on ultrasonography and hence they are usually not diagnosed preoperatively. Removal of the accessory gallbladder is necessary to avoid recurrence of symptoms. H-type accessory gallbladder is a rare anomaly. Once identified intra-operatively during laparoscopic cholecystectomy, the surgery is usually converted to open. By using the main gallbladder for liver traction and doing a dome down technique for the accessory gallbladder, we were able to perform the double cholecystectomy with intra-operative cholangiogram laparoscopically. Laparoscopic cholecystectomy was performed in 27-year-old male for biliary colic. Prior imaging with computer tomography-scan and ultrasound did not show a duplicated gallbladder. Intraoperatively after ligation of cystic artery and duct an additional structure was seen on its medial aspect. Intraoperative cholangiogram confirmed the patency of intra-hepatic and extra-hepatic biliary ducts. Subsequent dissection around this structure revealed a second gallbladder with cystic duct (H-type). Pathological analysis confirmed the presence of two gallbladders with features of chronic cholecystitis. It is important to use cholangiogram to identify structural anomalies and avoid complications.

Is American College of Surgeons NSQIP organ space infection a surrogate for pancreatic fistula?

BACKGROUND: In the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP), pancreatic fistula has not been monitored, although organ space infection (OSI) data are collected. Therefore, the purpose of this analysis was to determine the relationship between ACS NSQIP organ space infection and pancreatic fistulas. STUDY DESIGN: From 2007 to 2011, 976 pancreatic resection patients were monitored via ACS NSQIP at our institution. From this database, 250 patients were randomly chosen for further analysis. Four patients were excluded because they underwent total pancreatectomy. Data on OSI were gathered prospectively. Data on pancreatic fistulas and other intra-abdominal complications were determined retrospectively. RESULTS: Organ space infections (OSIs) were documented in 22 patients (8.9%). Grades B (n = 26) and C (n = 5) pancreatic fistulas occurred in 31 patients (12.4%); grade A fistulas were observed in 38 patients (15.2%). Bile leaks and gastrointestinal (GI) anastomotic leaks each developed in 5 (2.0%) patients. Only 17 of 31 grade B and C pancreatic fistulas (55%), and none of 38 grade A fistulas were classified as OSIs in ACS NSQIP. In addition, only 2 of 5 bile leaks (40%) and 2 of 5 GI anastomotic leaks (40%) were OSIs. Moreover, 3 OSIs were due to bacterial peritonitis, a chyle leak, and an ischemic bowel. CONCLUSIONS: This analysis suggests that the sensitivity (55%) and specificity (45%) of organ space infection (OSI) in ACS NSQIP are too low for OSI to be a surrogate for grade B and C pancreatic fistulas. We concluded that procedure-specific variables will be required for ACS NSQIP to improve outcomes after pancreatectomy.

Abnormal serum pancreatic enzymes, but not pancreatitis, are associated with an increased risk of malignancy in patients with intraductal papillary mucinous neoplasms.

INTRODUCTION: Pancreatitis is associated with intraductal papillary mucinous neoplasm (IPMN). This association is in part due to inflammation from pancreatic ductal obstruction. Although the correlation between pancreatitis and the malignant potential of IPMN is unclear, the 2012 International Consensus Guidelines (ICG) consider pancreatitis a "worrisome feature." We hypothesized that serum pancreatic enzymes, markers of inflammation, are a better predictor of malignancy than pancreatitis in patients with IPMN. METHODS: Between 1992 and 2012, 364 patients underwent resection for IPMN at a single university hospital. In the past decade, serum amylase and lipase were collected prospectively as an inflammatory marker in 203 patients with IPMN at initial surveillance and "cyst clinic" visits. The latest serum pancreatic enzyme values within 3 months preoperatively were studied. Pancreatitis was defined according to the 2012 revision of the Atlanta Consensus. RESULTS: Of the 203 eligible patients, there were 76 with pancreatitis. Pancreatitis was not associated with an increased rate of malignancy (P = .51) or invasiveness (P = .08). Serum pancreatic enzymes categorically outside of normal range (high or low) were also not associated with malignancy or invasiveness. In contrast, as a continuous variable, the higher the serum pancreatic enzymes were, the greater the rate of invasive IPMN. Of the 127 remaining patients without pancreatitis, serum pancreatic enzymes outside of normal range (low and high) were each associated with a greater rate of malignancy (P < .0001 and P = .0009, respectively). Serum pancreatic enzyme levels above normal range (high) were associated with a greater rate of invasiveness (P = .02). CONCLUSION: In patients with IPMN without a history of pancreatitis, serum pancreatic enzymes outside of the normal range are associated with a greater risk of malignancy. In patients with a history of pancreatitis, there is a positive correlation between the levels of serum pancreatic enzymes and the presence of invasive IPMN. These data suggest serum pancreatic enzymes may be useful markers in stratification of pancreatic cancer risk in patients with IPMN.

Preoperative predictors of weight loss following bariatric surgery: systematic review.

BACKGROUND: Obesity affects 32% of adults in the USA. Surgery generates substantial weight loss, but 20-30% fails to achieve successful weight loss. Our objective was to identify preoperative psychosocial factors associated with weight loss following bariatric surgery. METHODS: We performed a literature search of PubMed® and the Cochrane Database of Reviews of Effectiveness between 1988 and April 2010. Articles were screened for bariatric surgery and weight loss if they included a preoperative predictor of weight loss: body mass index (BMI), preoperative weight loss, eating disorders, or psychiatric disorder/substance abuse. One thousand seven titles were reviewed, 534 articles screened, and 115 included in the review. RESULTS: Factors that may be positively associated with weight loss after surgery include mandatory preoperative weight loss (7 of 14 studies with positive association). Factors that may be negatively associated with weight loss include preoperative BMI (37 out of 62 studies with negative association), super-obesity (24 out of 33 studies), and personality disorders (7 out of 14 studies). Meta-analysis revealed a decrease of 10.1% excess weight loss (EWL) for super-obese patients (95% confidence interval (CI) [3.7-16.5%]), though there was significant heterogeneity in the meta-analysis, and an increase of 5.9% EWL for patients with binge eating at 12 months after surgery (95% CI [1.9-9.8%]). CONCLUSIONS: Further studies are necessary to investigate whether preoperative factors can predict a clinically meaningful difference in weight loss after bariatric surgery. The identification of predictive factors may improve patient selection and help develop interventions targeting specific needs of patients.

Patient behaviors associated with weight regain after laparoscopic gastric bypass.

BACKGROUND: Patients undergoing gastric bypass lose substantial weight, but 20% regain weight starting at 2 years after surgery. Our objective was to identify behavioral predictors of weight regain after laparoscopic Roux-en-Y gastric bypass (LRYGB). METHODS: We retrospectively surveyed 197 patients for factors predictive of weight regain (≥15% from lowest weight to weight at survey completion). Consecutive patients who had bariatric surgery from 1/2003 through 12/2008 were identified from an existing database. Response rate was 76%, with 150 patients completing the survey. RESULTS: Follow-up after LRYGB was 45.0 ± 12.7 months, 22% of patients had weight regain. After controlling for age, gender, and follow-up time, factors associated with weight regain included low physical activity (odds ratio (OR) 6.92, P = 0.010), low self-esteem (OR 6.86, P = 0.008), and Eating Inventory Disinhibition (OR 1.30, P = 0.029). CONCLUSIONS: Physical activity, self-esteem, and maladaptive eating may be associated with weight regain after LRYGB. These factors should be addressed in prospective studies of weight loss following bariatric surgery, as they may identify patients at risk for weight regain who may benefit from tailored interventions.

Behavioral factors associated with successful weight loss after gastric bypass.

Patients undergoing bariatric surgery lose substantial weight (> or = 50% excess weight loss [EWL]), but an estimated 20 per cent fail to achieve this goal. Our objective was to identify behavioral predictors of weight loss after laparoscopic Roux-en-Y gastric bypass. We retrospectively surveyed 148 patients using validated instruments for factors predictive of weight loss. Success was defined as > or =50 per cent EWL and failure as <50 per cent EWL. Mean follow-up after laparoscopic Roux-en-Y gastric bypass was 40.1 +/- 15.3 months, with 52.7 per cent of patients achieving successful weight loss. After controlling for age, gender, and preoperative body mass index, predictors of successful weight loss included surgeon follow-up (odds ratio [OR] 8.2, P < 0.01), attendance of postoperative support groups (OR 3.7, P = 0.02), physical activity (OR 3.5, P < 0.01), single or divorced marital status (OR 3.2, P = 0.03), self-esteem (OR 0.3, P = 0.02), and binge eating (OR 0.9, P < 0.01). These factors should be addressed in prospective studies of weight loss after bariatric surgery, as they may identify patients at risk for weight loss failure who may benefit from early tailored interventions.

Indications for performing carpal tunnel surgery: clinical quality measures.

BACKGROUND: Rates of carpal tunnel surgery vary for unclear reasons. In this study, the authors developed measures determining when surgery is necessary (benefits exceed risks), inappropriate (risks outweigh benefits), or optional. METHODS: Measures were developed using a modified-Delphi panel. Clinical scenarios were defined incorporating symptom severity, symptom duration, clinical probability of carpal tunnel syndrome, electrodiagnostic testing, and nonoperative treatment response. A multidisciplinary panel of 11 carpal tunnel syndrome experts rated appropriateness of surgery for each scenario on a scale ranging from 1 to 9 scale (7 to 9, surgery is necessary; 1 to 3, surgery is inappropriate). RESULTS: Of 90 scenarios (36 for mild, 36 for moderate, and 18 for severe symptoms), panelists judged carpal tunnel surgery as necessary for 16, inappropriate for 37, and optional for 37 scenarios. For mild symptoms, surgery is generally necessary when clinical probability of carpal tunnel syndrome is high, there is a positive electrodiagnostic test, and there has been unsuccessful nonoperative treatment. For moderate symptoms, surgery is generally necessary with a positive electrodiagnostic test involving two or more of the following: high clinical probability, unsuccessful nonoperative treatment, and symptoms lasting longer than 12 months. Surgery is generally inappropriate for mild to moderate symptoms involving two or more of the following: low clinical probability, no electrodiagnostic confirmation, and nonoperative treatment not attempted. For severe symptoms, surgery is generally necessary with a positive electrodiagnostic test or unsuccessful nonoperative treatment. CONCLUSIONS: These are the first formal measures assessing appropriateness of carpal tunnel surgery. Applying these measures can identify underuse (failure to provide necessary care) and overuse (providing inappropriate care), giving insight into variations in receipt of this procedure.

Exercise following bariatric surgery: systematic review.

The contribution of physical activity on the degree of weight loss following bariatric surgery is unclear. To determine impact of exercise on postoperative weight loss. Medline search (1988-2009) was completed using MeSH terms including bariatric procedures and a spectrum of patient factors with potential relationship to weight loss outcomes. Of the 934 screened articles, 14 reported on exercise and weight loss outcomes. The most commonly used instruments to measure activity level were the Baecke Physical Activity Questionnaire, the International Physical Activity Questionnaire, and a variety of self-made questionnaires. The definition of an active patient varied but generally required a minimum of 30 min of exercise at least 3 days per week. Thirteen articles reported on exercise and degree of postoperative weight loss (n = 4,108 patients). Eleven articles found a positive association of exercise on postoperative weight loss, and two did not. Meta-analysis of three studies revealed a significant increase in 1-year postoperative weight loss (mean difference = 4.2% total body mass index (BMI) loss, 95% confidence interval (CI; 0.26-8.11)) for patients who exercise postoperatively. Exercise following bariatric surgery appears to be associated with a greater weight loss of over 4% of BMI. While a causal relationship cannot be established with observational data, this finding supports the continued efforts to encourage and support patients' involvement in post-surgery exercise. Further research is necessary to determine the recommended activity guidelines for this patient population.

Does weight loss immediately before bariatric surgery improve outcomes: a systematic review.

BACKGROUND: Preoperative weight loss before bariatric surgery has been proposed as a predictive factor for improved patient compliance and the degree of excess weight loss achieved after surgery. In the present study, we sought to determine the effect of preoperative weight loss on postoperative outcomes. METHODS: A search of MEDLINE was completed to identify the patient factors associated with weight loss after bariatric surgery. Of the 909 screened reports, 15 had reported on preoperative weight loss and the degree of postoperative weight loss achieved. A meta-analysis was performed that compared the postoperative weight loss and perioperative outcomes in patients who had lost weight preoperatively compared to those who had not. RESULTS: Of the 15 articles (n = 3404 patients) identified, 5 found a positive effect of preoperative weight loss on postoperative weight loss, 2 found a positive short-term effect that was not sustained long term, 5 did not find an effect difference, and 1 found a negative effect. A meta-analysis revealed a significant increase in the 1-year postoperative weight loss (mean difference of 5% EWL, 95% confidence interval 2.68-7.32) for patients who had lost weight preoperatively. A meta-analysis of other outcomes revealed a decreased operative time for patients who had lost weight preoperatively (mean difference 23.3 minutes, 95% confidence interval 13.8-32.8). CONCLUSION: Preoperative weight loss before bariatric surgery appears to be associated with greater weight loss postoperatively and might help to identify patients who would have better compliance after surgery.

Acute small bowel perforation after wireless capsule endoscopy in a patient with Crohn's disease: a case report.

INTRODUCTION: Wireless capsule endoscopy is an important tool for minimally invasive evaluation of the small bowel, allowing improved diagnostic yield with low complication rates relative to traditional modalities. Recently however, reports on small bowel perforation after wireless capsule endoscopy have surfaced. Here we present the first case of acute small bowel perforation in a middle-aged male in the United States. CASE PRESENTATION: A 58-year-old male with a presumed quiescent history of Crohn's Disease presented to the Emergency Department in a septic state 48 hours after a wireless capsule endoscopy procedure complaining of abdominal pain, distension, and frequent emesis. A computed tomography scan of the abdomen was suggestive of small bowel perforation and ischemic enteritis. The patient was adequately resuscitated and taken to the operating room for an ileocecectomy and extensive resection of the small bowel. Pathology of the resected specimen revealed an ileal stricture and associated necrotizing ileitis, and a perforation just proximal to the stricture. CONCLUSION: Wireless capsule endoscopy remains the preferred endoscopic imaging method of the small bowel. This case illustrates the importance of appropriate patient selection and evaluation of functional patency of the small bowel prior to wireless capsule endoscopy, especially with the growing role of this procedure in the evaluation of inflammatory bowel disease.

Developing quality indicators for elderly surgical patients.

OBJECTIVE: To develop process-based quality indicators to improve perioperative care for elderly surgical patients. BACKGROUND: The population is aging and expanding, and physicians must continue to optimize elderly surgical care to meet the anticipated increase in surgical services. We sought to develop process-based quality indicators applicable to virtually all disciplines of surgery to identify necessary and meaningful ways to improve surgical care and outcomes in the elderly. METHODS: We identified candidate perioperative quality indicators for elderly patients undergoing ambulatory, or major elective or nonelective inpatient surgery through structured interviews with thought leaders and systematic reviews of the literature. An expert panel of physicians in surgery, geriatrics, anesthesia, critical care, internal, and rehabilitation medicine formally rated the indicators using a modification of the RAND/UCLA Appropriateness Methodology. RESULTS: Ninety-one of 96 candidate indicators were rated as valid. They were categorized into 8 domains: comorbidity assessment, elderly issues, medication use, patient-provider discussions, intraoperative care, postoperative management, discharge planning, and ambulatory surgery. Of note, 71 (78%) of the indicators rated as valid address processes of care not routinely performed in younger surgical populations. CONCLUSIONS: Attention to the quality of care in elderly patients is of great importance due to the increasing numbers of elderly undergoing surgery. This project used a validated methodology to identify and rate process measures to achieve high quality perioperative care for elderly surgical patients.

What is the rate of small bowel obstruction after colectomy?

The rate of small bowel obstruction (SBO) after colectomy is unknown. Given the large number of colectomies performed in the United States, elucidating SBO rates, outcomes, and identifying predictors of readmission is important. Using the California Inpatient File, we identified all patients readmitted with a principle diagnosis of SBO at least once in the 3 years after colectomy (n = 4555). Patients admitted with a diagnosis of SBO in the 3 years before surgery were excluded. Overall, 10 per cent of patients were readmitted for SBO at least once after colectomy. Approximately 58 per cent were readmitted in the first year and 22 per cent of these patients required surgery. The most common operation performed was lysis of adhesions. Median length of stay was twice as long in the surgery group versus the no surgery group (12 vs 6 days). Overall mortality was higher in the nonsurgery group compared with the surgery group (33% vs 21%, P < 0.001) and highest in the elderly (44% vs 30%, P < 0.001). One in 10 patients without a history of SBO who undergoes a colectomy will be readmitted at least once in the subsequent 3 years for SBO, and there is a high mortality rate in this group, especially in the elderly.

A structured conference program improves competency-based surgical education.

BACKGROUND: Work hour restrictions and new educational standards pose substantial challenges for modern residency programs. We present results from an institutional effort to improve resident education using a competency-based conference program. METHODS: The conference program is a weekly 3-hour mandatory block of protected time including a formal lecture series and a modular series tailored to resident level. A comprehensive survey was administered to all general surgery residents before (2005) and after (2006) implementation of the new conference program and included specific items related to the 6 competencies. RESULTS: Scores for 16 competency-related items all showed statistically significant improvement. We also found improvements in residents' perceptions of the faculty. Overall, the new conference program was rated positively by 98% of residents. CONCLUSIONS: Implementation of a structured conference program resulted in significant improvement in residents' evaluation of their education in the 6 competencies and improved their perceptions of the faculty.
