Abstract：
:Colonic angiodysplasia is now recognized as a frequent cause of gastrointestinal bleeding in patients over age 55. These microvascular arteriovenous malformations may be as common a cause of colonic bleeding as diverticular disease. The lesions are not evident on barium studies. Even colonoscopy and selective colonic angiography can give false-negative results. Therefore, repeated studies for recurrent episodes of bleeding are often necessary before the diagnosis is made. Methods of treatment include coagulation biopsy, segmental colon resection and right hemicolectomy.
