Diverticular bleeding is a common cause of lower gastrointestinal bleeding in adults. Most of colonic diverticular bleeding stop spontaneously without any treatment. But diverticular bleeding develops at arterial vessel, which results in massive bleeding in a short period of time and may shows recurrence. Acute lower intestinal bleeding has been treated with heater probe coagulation, injection therapy, bipolar coagulation and endoscopic hemoclips. We experienced a 67-year-old woman presented hematochezia. Emergency colonoscopy was performed and showed a diverticulum with a visible vessel at the cecum. Hemostasis with hemoclip was successfully done. We herein report a case of hemostasis by capping a diverticulum of the colon with hemoclips.
