Minimally invasive surgery has revolutionized the treatment of gastrointestinal tumors. Submucosal tumors of the stomach can be resected using laparoscopic techniques. We report here a case of ectopic pancreas tissue in the gastric wall that was removed using robotic-assisted laparoscopic resection. The patient was a 15-year-old female who presented with abdominal discomfort and tarry stools. Laboratory analysis showed iron deficiency anemia. Preoperative endoscopy revealed a submucosal lesion in the posterior wall of the gastric high body. Intraoperative upper endoscopy clearly located the lesion. A robotic-assisted laparoscopic wedge resection of the putative gastric submucosal tumor was performed. The pathology results showed an ectopic pancreas. The patient had an uneventful recovery and we believe that this is a valid treatment option for this benign condition.
