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.
异位胰腺是一种以异位胰腺组织为特征的先天性异常。异位胰腺的治疗方法可能包括观察等待、内镜切除或手术。本报告的目的是描述结扎辅助内镜黏膜切除术（EMR）治疗胃异位胰腺的技术。两名患者（均为女性，平均年龄32岁）因胃上皮下肿瘤前来就诊。两人的内镜超声检查均显示黏膜和黏膜下层有小的低回声肿块。两例均行结扎辅助EMR，无并发症发生。切除肿瘤的病理检查显示为起源于黏膜下层的异位胰腺。切缘无胰腺组织。结扎辅助EMR技术上可行，可考虑用于内镜治疗异位胰腺。
