Abstract
Hemorrhage associated with small-bowel varices is an uncommon, difficult to treat, and often fatal manifestation of portal hypertension. There are no precise data on the incidence of this cause of bleeding. The main cause is portal hypertension or a local stenosis or thrombosis of the superior mesenteric vein. About 8.1% of patients with portal hypertension who underwent capsule endoscopy have small-bowel varices.1 Varices have been found both in the proximal and distal small bowel. At ileocoloscopy, 18% of patients with liver cirrhosis and portal hypertension have ileal varices.
