Abstract
- Colorectal varix (CRV) is a rare cause of lower gastrointestinal bleeding and usually associated with portal hypertension from liver cirrhosis or portal venous obstruction. Idiopathic CRV have no identifiable underlying cause and can only be diagnosed after the cause of portal or mesenteric vein circulation have been excluded. We report a case of idioipathic CRV presented with rectal bleeding for a week. Colonoscopy revealed markedly dilatated tortuous, and bluish veins in the rectum as well as coexistent adenomatous polyp and internal hemorrhoid. Despite extensive investigation, there was no evidence of portal hypertension or any other cause. Family history was also negative. Although blood transfusions were required, the patient remained asymptomatic without further rectal bleeding.
