A 83-year-old man was transferred to our department for investigation of bloody stool, fever and dizziness. He had a history of bronchial asthma. He was diagnosed with diverticulitis at the ileum by abdominal computed tomography and was suspected of having diverticular bleeding. The bleeding did not stop by conservative treatment. We performed colonoscopy and identified the site of bleeding and diverticulitis. We diagnosed the patient with diverticular bleeding and diverticulitis in the terminal ileum. Hemostasis by clipping was attempted and no recurrence of bleeding after the treatment. Seven days after admission, diverticulitis improved and he resumed eating. We here present a case of diverticular bleeding at terminal ileum treated by endoscopy.
