Endoscopy-assisted laparoscopic resection of gastric heterotopic pancreas

This is a case report of a 51-year-old white female who underwent an endoscopy-assisted laparoscopic resection of a submucosal mass in the prepyloric region of the stomach, which turned out to be heterotopic pancreas. She presented with vague upper gastrointestinal complaints of pain, early satiety, nausea, vomiting, and an 8 pound weight loss. Her only diagnostic workup was an upper endoscopy, which revealed this submucosal umbilicated mass. This manuscript provides a detailed description of the operation and a discussion and review of the literature about gastric heterotopic pancreas.
