Ectopic pancreas is defined as pancreatic tissue found outside the usual anatomic location. It is often found incidentally at different sites in the gastrointestinal (GI) tract. The incidence of ectopic pancreatic tissue in autopsy series is 1% to 2%, with 70% of the ectopic lesions found in the stomach, duodenum and jejunum. Although it is usually a silent anomaly, an ectopic pancreas may become clinically evident when complicated by inflammation, bleeding, obstruction or malignant transformation. We report a case of ectopic pancreas located in the jejunum and presenting as an obscure GI bleeding, which was diagnosed by capsule endoscopy.
异位胰腺被定义为在正常解剖位置以外发现的胰腺组织。它常于胃肠道不同部位被偶然发现。尸检系列中异位胰腺组织的发生率为1%至2%，其中70%的异位病变见于胃、十二指肠和空肠。尽管它通常是一种隐匿性异常，但当并发炎症、出血、梗阻或恶变时，异位胰腺可能会在临床上显现出来。我们报告一例位于空肠的异位胰腺，表现为不明原因的胃肠道出血，经胶囊内镜检查得以确诊。
