Two Cases of Heterotopic Pancreas of the Small Bowel Incidentally Found During Laparoscopic Bariatric Surgery.

Background: We present two cases of incidentally found heterotopic pancreas during laparoscopic bariatric surgery. Heterotopic pancreas is a rare congenital anomaly where pancreatic tissue is located outside of the pancreas. These lesions may be encountered incidentally during surgery, which raise unexpected management questions. Case 1: A single pathology confirmed ectopic pancreas lesion encountered in the jejunem during laparoscopic Roux-en Y gastric bypass. Case 2: Two pathology confirmed heterotopic pancreas lesions encountered in the jejunem during laparoscopic Roux-en Y gastric bypass. Discussion: Heterotopic pancreas lesions are generally benign and encountered incidentally during intra-abdominal surgery. Surgeons must decide whether to resect the incidentally found mass. When encountered intraoperatively, a heterotopic pancreas lesion found in the small bowel without concerning features should be considered benign and does not warrant resection or biopsy.

Two unique cases of Bouveret syndrome with review of literature.

Bouveret syndrome is a rare form of gallstone ileus in which a proximally lodged gallstone in the duodenum causes a gastric outlet obstruction. It is a rare condition that can be challenging to manage. Although endoscopic management remains first line, a surgical approach can be needed. We present two cases of Bouveret syndrome. A 65-year-old man with oral squamous cell carcinoma treated with endoscopic management and a 63-year-old woman treated with surgery.

Surgical Management of Bronchobiliary Fistula After Thoracoabdominal Trauma.

Bronchobiliary fistulas are exceedingly rare pathological connections between the biliary and the bronchial systems, which result from hepatobiliary neoplasms, abscesses, or thoracoabdominal trauma. Prompt recognition, diagnosis, and intervention is essential in order to prevent the high morbidity and mortality associated with this disease process. Multiple management strategies have been described in the literature; however, the optimal course has not been well defined. We present a case of a 31-year-old male who developed a bronchobiliary fistula 1 month after thoracoabdominal trauma. After conservative management with biliary stenting failed, he successfully underwent latissimus sparing right posterolateral thoracotomy, complete fistulectomy, right lower lobe wedge resection, and diaphragmatic reconstruction with subsequent resolution of his symptoms.

Bile duct injuries: a contemporary survey of surgeon attitudes and experiences.

INTRODUCTION: The incidence of bile duct injury (BDI) during laparoscopic cholecystectomy has not changed significantly in the past 2 decades despite increased operative experience and technical refinement. We sought to evaluate surgeon-specific factors associated with BDI and to assess how surgeons manage injuries. METHODS: An online survey was sent to surgeons belonging to the Society of American Gastrointestinal and Endoscopic Surgeons via e-mail. Survey items included personal experience with BDI and how injuries were addressed. Statistical analysis was performed to identify factors associated with BDI. RESULTS: The survey was sent to 3411 surgeons with 559 complete responses (16.5%). The mean age of respondents was 48.7 years with an average time in practice of 16.1 years. Most respondents (61.2%) had fellowship training. Forty-seven percent of surgeons surveyed experienced a BDI in their career with 17.1% of surgeons experiencing multiple BDIs. The majority of BDIs were identified in the operating room (64.5%); most injuries (66.9%) were repaired immediately. When repair was undertaken immediately, 77.4% of these repairs were performed in an open technique. A majority of surgeons (57.7%) felt that BDIs could theoretically be repaired laparoscopically and 25% of those surgeons had done so in practice. In multivariate logistic regression, any type of fellowship training was associated with a decreased risk of BDI (OR 0.51, 95% CI 0.34-0.76). Compared with those in non-academic practice, surgeons in academic practice were at a significantly decreased risk of having experienced a BDI (OR 0.62, 95% CI 0.42-0.92). CONCLUSION: Nearly half of those surveyed, experienced a BDI during a laparoscopic cholecystectomy. Community and private practice setting were associated with an increased risk of BDI, while fellowship training and academic practice setting conferred a protective effect. A majority of surgeons felt that BDI could be repaired laparoscopically and 25% had done so in practice.

Predictability of first-year weight loss in laparoscopic sleeve gastrectomy.

BACKGROUND: Bariatric surgery is a significant investment for the patient and weight loss team. In some cases, this includes a requirement for pre-operative weight loss despite the lack of evidence for a correlation with successful outcomes. We sought to determine whether weight loss on a short, immediate pre-operative diet, as well as across the medical weight loss program, would correlate with 1-year outcomes of patients undergoing laparoscopic sleeve gastrectomy (LSG). METHODS: All patients having a LSG between March 2013 and March 2016 were reviewed. Demographics and biometrics [weight, body mass index (BMI)] were collected at initial, day of surgery and follow-up (2 weeks, 6 weeks, 4 months, and 1 year). Pre-operative weight loss was determined both cumulative (initial to day of surgery) and for the pre-operative diet (2 weeks). Weight loss and percent excess weight loss (%EWL) were calculated and correlated at all time points. RESULTS: A total of 127 patients were reviewed for this study. The mean %EWL at 1-year follow-up was 47 ± 18%. Weight loss achieved on a 2-week pre-operative diet did not correlate with weight outcomes at 1-year follow-up (r = 0.134, p = 0.40); however, cumulative pre-operative weight loss had a modest correlation (r = 0.443, p < 0.01). Post-operative %EWL at 4 months had the best correlation with longer term weight loss (r = 0.730, p < 0.01). CONCLUSIONS: Pre-operative performance is not a good predictor for 1-year outcomes in LSG. Better correlation was observed in %EWL at post-surgery visits. Following the patient's trajectory post-operatively may provide a window for intervention to improve weight loss.

Current practices in biliary surgery: Do we practice what we teach?

INTRODUCTION: Since the widespread adoption of laparoscopic techniques in biliary surgery, the incidence of bile duct injures (BDI) has not significantly declined despite increased operative experience and recognition of the critical view of safety (CVS) method for anatomic identification. We hypothesized that operative approaches in clinical practice may vary from well-described technical recommendations. The objective of this study was to access how practicing surgeons commonly identify anatomy during laparoscopic cholecystectomy (LC). METHODS: We performed a cohort study assessing practices in biliary surgery among current practicing surgeons. Surgeons belonging to the Midwest Surgical Association and the Society of American Gastrointestinal and Endoscopic Surgeons were surveyed. Items surveyed include preferred methods for cystic duct identification, recognition of the CVS, and use of intraoperative imaging. RESULTS: In total, 374 of 849 surgeons responded. The CVS was not correctly identified by 75 % of surgeons descriptively and by 21 % of surgeons visually. 56 % of surgeons practiced the infundibular method for identification of the cystic duct; 27 % practiced the CVS method. Intraoperative cholangiography was used by 16 % and laparoscopic ultrasound by <1 %. CONCLUSION: A majority of surgeons preferably do not use the CVS method of identification during LC. A large percentage of practicing surgeons are unable to describe or visually identify the CVS. These results suggest an urgent need to reexamine the tenets of how LC is being taught and disseminated and present a clear target for improvement to reduce BDI.

Single-incision cholecystectomy for left-sided gallbladder.

True left-sided gallbladder (sinistroposition) is a rare anatomic anomaly in which the gallbladder is found to the left of the falciform ligament, under the left lobe of the liver. Though uncommon, it is important for the surgeon to recognize this finding because the ductal anatomy is unique and the mechanics of the operation provide a technical challenge. Multiple case reports have documented safe management of sinistroposition encountered during conventional laparoscopic cholecystectomy. We present a case of sinistroposition encountered during a single-incision laparoscopic cholecystectomy. We believe that the single-site laparoscopic technique is not only a safe option but may actually provide certain benefits in approaching this difficult anatomy in the properly selected patient and the experienced single-site surgeon's hands.

Pre-Lap-Band group education in Medicaid population: does it really make a difference?

BACKGROUND: The effect of group education classes before a Lap-Band procedure has not been well defined. We hypothesized that in a Medicaid population, the completion of a standardized 12-week multidisciplinary preoperative program (SMPP) would significantly improve the preoperative and early postoperative weight loss. All procedures were performed at a University-affiliated community hospital from 2006 to 2007. METHODS: A prospectively collected database of 292 patients who underwent Lap-Band placement was retrospectively reviewed. All patients in the study cohort were encouraged to participate in the SMPP, which included medical, psychological, and nutritional interventions. The patients were divided into 2 groups according to their participation in the SMPP program: SMPP compliant and non-SMPP compliant. The postoperative weight loss of these 2 groups was then compared using the general linear models for repeated measures statistical analysis. RESULTS: No significant difference was found in the mean baseline excess body weight between the 2 groups (74 +/- 20 kg in the SMPP-compliant and 76 +/- 20 kg in the non-SMPP-compliant participants). The mean baseline body mass index (47 +/- 7 versus 48 +/- 72 kg/m(2) for the SMPP-compliant and non-SMPP-compliant participants) was also similar in the 2 groups. The postoperative follow-up rate was 94.5% at 1 month, 72.3% at 6 months, and 52.7% at 12 months. The excess weight loss was significantly greater in the SMPP compliant group than in the noncompliant group during the observed 12-month follow-up period (P = .04, by general linear models for repeated measures). CONCLUSION: In a Medicaid population, implementation of an intensive preoperative SMPP resulted in a significant improvement in the short-term weight loss after Lap-Band placement.
