title: Bleeding angiodysplasia of the gastrointestinal tract.
abstract: Bleeding angiodysplasia of the gastrointestinal tract poses frustrating challenges to clinicians because these minute vascular lesions are difficult to diagnose pre-operatively and to locate intra-operatively. During the past 12 years, 24 patients were treated for histopathologically confirmed bleeding angiodysplasia of the gastrointestinal tract. Pre-operative investigations and intra-operative localization followed a fixed protocol for patients with gastrointestinal bleeding of obscure origin. The median follow-up of these 24 patients was 51 months and the results of treatment for 22 patients were excellent. Two patients had recurrent bleeding but investigations failed to determine the bleeding source.
