Abstract

Dieulafoy's lesions are characterized by a single large tortuous arteriole in the submucosa, and this arteriole does not undergo normal branching. These lesions are an uncommon cause of massive, sometimes fatal gastrointestinal bleeding; this had been reported to be the cause of 0.3~1.5% of the cases of major gastrointestinal bleeding. The lesions mainly occur in the proximal stomach, but they may occur in all parts of the gastrointestinal tract, including the small bowel, colon and rectum. Endoscopy is a common method for the diagnosis and treatment of Dieulafoy's lesions. However, in the case of a high risk lesion, angiography, laparoscopy or laparotomy can be performed instead. We experienced a rare case of bleeding from a Dieulafoy's lesion with pseudoaneurysm in the sigmoid colon. Angiography with embolization was performed, but the patient expired due to rebleeding. We report on this case along with a review of the relevant literature.
