Abstract

Heterotopic pancreas is a congenital anomaly characterized by ectopic pancreatic tissue. Treatment of heterotopic pancreas may include expectant observation, endoscopic resection or surgery. The aim of this report was to describe the technique of ligation-assisted endoscopic mucosal resection (EMR) for resection of heterotopic pancreas of the stomach. Two patients (both female, mean age 32 years) were referred for management of gastric subepithelial tumors. Endoscopic ultrasound in both disclosed small hypoechoic masses in the mucosa and submucosa. Band ligation-assisted EMR was performed in both cases without complications. Pathology from the resected tumors revealed heterotopic pancreas arising from the submucosa. Margins were free of pancreatic tissue. Ligation-assisted EMR is technically feasible and may be considered for the endoscopic management of heterotopic pancreas.
