Idiopathic Ileocolonic Varices Coexisting with a Colon Polyp Treated Successfully by Endoscopy: A Case Report and Literature Review.

Colonic varices are usually associated with portal hypertension. Idiopathic colonic varices are extremely rare. A 68-year-old man with a positive fecal occult blood test result underwent colonoscopy. We detected idiopathic ileocolonic varices and a coexisting ascending colon polyp. While reviewing the literature, we found cases of biopsies and polypectomies resulting in significant bleeding. We herein report a case of idiopathic ileocolonic varices coexisting with a colon polyp treated successfully by endoscopy. The coexistence of colonic varices and a colorectal lesion that requires endoscopic treatment may lead to significant bleeding. During management, the development of a treatment strategy and obtaining informed consent are necessary.
