Abstract

Ectopic pancreatic tissue is an uncommon developmental anomaly. The condition mostly occurs in the gastrointestinal tract and is usually asymptomatic. It rarely causes symptoms of inflammation, bleeding and perforation, and has potential for malignant change. Though it is an uncommon condition, cases of ectopic pancreas have been reported worldwide. Preoperative diagnosis of ectopic pancreas is challenging because of its nonspecific symptoms and signs. Owing to the revolution of minimally invasive surgery, submucosal tumors of the stomach can be resected by laparoscopic techniques. We have earlier reported on a case of ectopic pancreas in the stomach treated by robotics-assisted laparoscopic wedge resection. Herein, we report a case of ectopic pancreas in the prepyloric region of the stomach. A 44-year-old female presented with a two-week history of epigastralgia with radiation to the back. She received endoscopy check-up which disclosed a mass in the stomach. By endoscopic findings, a submucosal lesion in the prepyloric region with umbilical folding on the mucosa was identified. The umbilical folding on the mucosa hint the orifice of the duct of ectopic pancreas into the gastric mucosa suggestive of ectopic pancreas. Contrast-enhanced abdominal computed tomography showed a 5 cm cystic mass with heterogeneous content. To sum it up, the patient was diagnosed as ectopic pancreas in the stomach. She underwent laparoscopy-assisted antrectomy with Billroth I anastomosis (excision of the antrum and prepyloric region with reconstruction of gastrointestinal continuity by gastroduodenostomy) and had an uneventful hospitalization course. The histopathology of the resected tumor demonstrated ectopic pancreatic tissue in the gastric wall. To the best of our knowledge, excision of gastric ectopic pancreas using laparoscopy-assisted antrectomy with Billroth I anastomosis has never been reported in the literature.
