Diverticular Hemorrhage

The incidence of colonic diverticulosis appears to have increased in Japan, most likely due to an aging society and a change in diet from traditional fiber-rich foods to fat-rich foods. Two major complications of colonic diverticulosis are inflammation and bleeding, and diverticular hemorrhage is the most common cause of lower gastrointestinal bleeding. Right-sided colonic diverticulosis (cecum, ascending and transverse colon; RSD) is predominant in Asian countries, including Japan, whereas left-sided diverticulosis (rectum, sigmoid and descending colon; LSD) is far more frequent in Western population. The clinical courses of inflammation between RSD and LSD apparently differ since the latter is likely to worsen and require surgical intervention. However, little is known about whether or not the clinical profile of hemorrhage is different between RSD and LSD. The present retrospective study clarifies whether the clinical profiles of hemorrhage between RSD and LSD differ. The computed tomography is also done for detecting bleeding site. Colonoscopy is adapted if conservative treatment has failed or the course of the bleed needs to be investigated. Patients with unidentified bleeding sites were excluded. Clinical data, including age, sex, history of diverticular bleeding, comorbid disease, concomitant prescriptions, treatment
