Abstract
IntroductionHeterotopic pancreas, also known as ectopic pancreas, is defined as the presence of pancreatic tissue outside its normal location and without anatomic and vascular continuity with the main body of the pancreas. The incidence of heterotopic pancreas has been reported as 0.5 % during laparotomies and at autopsy ranging from 0.6–14 %. Presentation of caseA 28 years old obese male, medically free electively admitted for laparoscopic sleeve gastrectomy. Intraoperatively after dissecting the greater omentum from the stomach and inserting the 36 Fr gastric bougie, small oval shape mass about 1 cm close to the lesser curvature on the anterior surface of the gastric antrum. Macroscopically benign looking and a thorough laparoscopic exploration showed no signs of other organs involvement. Antrectomy and mini gastric bypass done. The postoperative course was uneventful. The histopathological examination of the antrectomy specimen showed heterotopic pancreas in the subserosa of gastric antrum. DiscussionThe Heterotopic pancreatic tissue can be discovered in the stomach (particularly antrum), duodenum, jejunum, or a Meckel diverticulum. Surgical resection is the mainstay treatment if the heterotopic pancreas is symptomatic or when the lesion is found incidentally during surgery in order to prevent complications. ConclusionHeterotopic pancreas should always be considered in the differential diagnosis of incidentally found gastric lesions and can be safely resected. This is the first case report of gastric heterotopic pancreas which is found incidentally during a bariatric surgery procedure.
