Abstract
Dieulafoy's maformation is an uncommon cause of massive GI bleeding. It consists of a large caliber-persistent artery in the submucosa, producing a minute protruding mucosal defect. Diagnosis typically requires multiple investigative modalities including endoscopy, nuclear RBC scan, angiography and laparotomy. We report a case of Dieulafoy's lesion in the jejunum, where the patient presented with hematochezia and hemodynamic instability. Initial endoscopy revealed a gastric ulcer and the patient underwent endoscopic hemostasis. Second-look endoscopy was performed due to persistent GI bleeding but the other bleeder was not detected. Nuclear RBC scan eventually revealed the bleeder in the jejunum, which was subsequently proved by laparotomy. Histopathology further confirmed the diagnosis of Dieualfoy's lesion in the jejunum.
