Background and Objectives: The preoperative work up for bariatric surgery is variable and not all centers perform a preoperative upper gastrointestinal endoscopy. A study was undertaken to determine the frequency of clinically significant gross endoscopic and pathological diagnoses in a large sample of patients with obesity undergoing work-up for bariatric surgery. Methods: Routine endoscopy was performed on all preoperative bariatric patients. A retrospective chart review of 1000 consecutive patients was performed. Patients were divided into three groups: Group A (no endoscopic findings), Group B (clinically insignificant findings), Group C (clinically significant findings). Results: Patients had a mean body mass index (BMI) of 49 kg/m2 and 79% were female. In this sample one finding was found on preoperative EGD in 95.2% of patients, 33.9% had at least two diagnoses, and 29.9% had three or more diagnoses. Group A (no findings) consisted of 4.8% of patient, 52.5% in Group B (clinically insignificant findings), and 42.7% were in Group C (clinically significant findings). Clinically significant findings included hiatal hernia 23.5%, esophagitis 9.5%, H. pylori 7.1%, gastric erosions 5.7%, duodenitis 3.7%, Barrett's esophagus 3.1%, and Schatzki ring 1.2%. There was no significant correlation between preoperative BMI and any endoscopic findings (all p-value 0.05). Patients in Group C were statistically older than Groups A and B. Conclusion: Upper gastrointestinal pathology is highly common in patients with obesity. There is a significant rate of clinically significant endoscopy findings and all bariatric surgery patients should undergo preoperative endoscopy.

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.

Introduction: Left sided gallbladder (sinistroposition) is a well described congenital abnormality that can pose an unexpected challenge for the surgeon, especially regarding port placement for safe and effective dissection.Case Description: In this case, a 36 -year-old woman with biliary colic was taken to the operating room for elective cholecystectomy and found, after port placement, to have sinistroposition of the gallbladder. The operation was completed with relative ease using our typical port placement of a 5 mm port at Palmer's point, a 12 mm port at the umbilicus; and two additional 5 mm ports, one in the right midclavicular line, and one in the right anterior axillary line.Discussion: Multiple port placements for safe and effective dissection of a left sided gallbladder have been discussed. Identification of sinistropic gallbladder often occurs after ports are already placed in position for right sided cholecystectomy. In this case, our typical port placement where the operating surgeon's right-hand port is located at Palmer's point provided excellent positioning for dissection. No alterations to the surgeon's lefthand port or the assistant port were necessary. The dissection was able to be completed from familiar angles, so dissection and identification of anatomy was performed with relative ease. This is important as sinistroposition can at times lead to abnormalities of the biliary tree, though none were noted in this case.

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.
