Heterotopic pancreatic tissue in the stomach is an uncommon gastric subepithelial lesion. Is usually an asymptomatic condition which is found incidentally. As with other gastric subepithelial lesions, diagnosis can be challenging. Endoscopic forceps biopsy specimens are of little value. Endoscopic ultrasound findings are helpful in characterize this lesions, but they cannot absolutely determine the type of lesion or whether a lesion is benign or malignant. The sequence endosonography- cap assisted endoscopic mucosal resection allows en bloc resection of small gastric subepithelial lesions with low complication rates. We report a case of an ectopic pancreas of the antrum in the stomach that arises from the second layer of the gastric wall (muscularis mucosa) at endoscopic ultrasound that was removed en bloc with cap-assisted endoscopic mucosal resection technique in one endoscopic session without complications.
胃内异位胰腺组织是一种罕见的胃上皮下病变。通常为无症状状态，多为偶然发现。与其他胃上皮下病变一样，诊断具有挑战性。内镜钳取活检标本价值不大。内镜超声检查结果有助于对这种病变进行特征性描述，但不能绝对确定病变类型或病变是良性还是恶性。内镜超声引导下帽辅助内镜黏膜切除术可整块切除小的胃上皮下病变，并发症发生率低。我们报告一例胃窦部异位胰腺，在内镜超声检查中发现其起源于胃壁第二层（黏膜肌层），通过帽辅助内镜黏膜切除技术在一次内镜操作中整块切除，无并发症发生。
