A-86-year male patient was transferred to our department for investigation of two episodes of bloody stool in August and October, X. Hemostasis was performed on a suspicion of colonic diverticulosis or capillary telangiectasia in the small intestine. The patient admitted to the hospital because of a recurrent bloody stool in December, X. Abdominal CT showed an extravasation of contrast from the terminal ileum. Lower GI endoscopy was performed but failed to detect the bleeding point. However, at the 4th episode of bloody stool after admission, endoscopy revealed active bleeding from one of multiple diverticula at 10-cm proximal to Bauhin’s valve in the terminal ileum. An exposed blood vessel was recognized after irrigation and hemostasis by clipping was attempted. The patient was discharged without any further bleeding episode. We here present a case of bleeding small intestinal diverticulosis in which the bleeding point was detected by abdominal CT and hemostasis was achieved by clipping during lower GI endoscopy. Our present case suggests that abdominal CT is useful in case with bleeding small intestinal diverticulosis.
