title: [Massive lower gastrointestinal hemorrhage after polypectomy due to a colon fistula of a pseudoaneurysm of the splenic artery caused by chronic pancreatitis].
abstract: A life-threatening lower gastrointestinal bleeding is a rare complication due to coloscopic polypectomy. The following case report deals with a severe bleeding that was caused by polypectomy of a villous adenoma in a patient with chronic pancreatitis causing a huge pseudoaneurysm of the splenic artery. After polypectomy a wide iatrogenic communication between the pseudoaneurysm and the colon existed causing massive arterial intraluminal bleeding. Although this was successfully managed by transcatheter arterial embolization via splenic artery, the patient died a few days later caused by disseminated intravasal anticoagulation and multi organ failure.
