Dieulafoy lesion is an uncommon cause of gastrointestinal bleeding, reported to be only 2% of acute or chronic upper gastrointestinal bleeding episodes. Bleeding occurs from a small mucosal erosion involving an unusually large submucosal artery in an otherwise normal mucosa. It is associated with massive, life threatening hemorrhage and is difficult to diagnosis. In most cases the lesion is encountered in the proximal stomach, antrum, duodenum, colon and rectum. In particular, extragastric Dieulafoy lesion is an extremely rare source of intestinal bleeding. In Korea, no case of bleeding from a Dieulafoy lesion of the small intestine has been previously reported. We experienced one case of bleeding from a jejunal Dieulafoy lesion, which was confirmed by the pathologic examination of the resected specimen, and report here.
Dieulafoy病变是胃肠道出血的一种罕见原因，据报道仅占急性或慢性上消化道出血病例的2%。出血源于一个小的黏膜糜烂，该糜烂累及一个在其他方面正常的黏膜中异常粗大的黏膜下动脉。它与大量危及生命的出血相关，且难以诊断。在大多数情况下，病变见于胃近端、胃窦、十二指肠、结肠和直肠。特别是，胃外Dieulafoy病变是肠道出血极其罕见的来源。在韩国，此前尚无小肠Dieulafoy病变出血的病例报告。我们经历了一例空肠Dieulafoy病变出血的病例，经切除标本的病理检查得以确诊，现于此报告。
