title: Colonic varices. Report of an unusual case diagnosed by radionuclide scanning, with review of the literature.
abstract: We report a patient who developed recurrent massive lower gastrointestinal bleeding after successful obliteration of esophageal varices by sclerotherapy. A radionuclide study was very helpful in establishing diagnosis of the lesion responsible, a varix in the cecal area. Bleeding subsided after creation of a portacaval anastomosis. The literature pertaining to colonic varices is reviewed.
