title: [Bleeding in diverticular disease of the colon].
abstract: The incidence of bleeding from diverticular disease ranges from 3 to 30%. Haemorrhage is more common when the whole colon is affected; the source is more frequently in the right colon. Typically, the bleeding is massive, with 15% of the patients admitted in shock. It nearly always stops spontaneously, but recurrence rate is high. Chronic blood loss suggests alternative sources. Emergency angiography detects aetiology and site of the haemorrhage in most of the patients. Vasopressin infusion can frequently stop the bleeding. Colonoscopy is profitable only when bleeding stops, after a rapid clearing of the colon. On the other hand, intraoperative colonoscopy could be useful in emergency cases when urgent surgery is clearly indicated. Surgical treatment is requested only in few patients: segmental resections (generally right hemicolectomy) are indicated when there is evidence of the source of the blood loss. In the other cases sub-total or total colectomy are justified and provide better and safer results.
