Colonic diverticular bleeding can result in hemorrhagic shock requiring blood transfusion, and it carries a high risk of recurrence within 1 year.

As a result, patients with colonic diverticular disease are often bothered by required frequent examinations, re-hospitalization, and a consequent decrease in quality of life. However, the management of diverticular disease differs between Japan and Western countries. For example, computed tomography (CT) is readily accessible at Japanese hospitals, so urgent CT may be selected as the first diagnostic procedure for suspected diverticular disease. Endoscopic clipping or band ligation may be preferred as the first endoscopic procedure for diverticular bleeding.
