Abstract
- Dieulafoy's lesion is an uncommon cause of gastrointestinal bleeding. However, it is clinically important in that it can be associated with recurrent and massive gastrointestinal bleeding. The bleeding results from an abnormal large submucosal artery. On endoscopy, a small mucosal defect with a protruding vessel or fresh clot may be visualized if the patient is actively bleeding. In most cases, the lesion is encountered in the proximal stomach within 6 cm of the gastroesophageal junction, but similar lesions have been described in the antrum, duodenum, colon, and rectum. In particular, jejunal Dieulafoy's lesion is extremely rare. We experienced one case of recurrent and massive bleeding from a proximal jejunal Dieulafoy's lesion, which was confirmed by the pathologic examination of the resected specimen.
