Abstract
As a consequence of cirrhosis, portal hypertension causes resistance to blood flow and leads to the formation of varices. However, colonic variceal hemorrhages are rarely reported but could be a lethal cause of lower gastrointestinal hemorrhage. Currently, there is no consensus on the management of colonic variceal hemorrhage. Variceal ligation, injection sclerotherapy, transjugular intrahepatic portosystemic shunt placement, and balloon-occluded retrograde transvenous obliteration or a combination of the above therapies have been reported with inconsistent success rates. We advocate considering colonic variceal bleeding as a crucial differential diagnosis of lower gastrointestinal bleeding in cirrhotic patients and initiating time-sensitive, definite operative treatment or combination therapy as soon as possible in colonic variceal patients with life-threatening bleeding events, which are often refractory to conservative treatment.
