    Abstract:
    We report herein the case of a 70-year-old woman who presented with massive bleeding from multiple jejunal diverticula. She was initially admitted to our hospital with massive melena. An upper gastrointestinal endoscopic examination revealed no bleeding site. Colonoscopy revealed clotted and red blood throughout the colon, and a small diverticulum in the ascending colon which was thought to be the source of bleeding. Following admission, she was treated conservatively at first, but melena continued and the anemia did not improve despite blood transfusions. A laparotomy was performed and multiple jejunal diverticula, distributed from 10 to 40 cm distal to the ligament of Treitz, were found. A segment of the jejunum containing all diverticula was resected. The most distal diverticulum contained a clot of blood, but no ulceration was observed. A histological examination revealed many dilated blood vessels in the mucosa and submucosa of this diverticulum, which were compatible with the findings of angiodysplasia. Based on these findings, we believe that angiodysplasia was the cause of bleeding from the jejunal diverticula in this case.
