Angiodysplasia is the most common vascular lesion of the gastrointestinal tract, and this condition may be asymptomatic, or it may cause gastrointestinal (GI) bleeding.
Twelve patients, five men and seven women, were found to have a total of 25 angiodysplasias (Table 1). Fourteen were located in the stomach and 11 in the duodenum, including five in the duodenal bulb and six in the descending part of the duodenum. None of the patients had features of Osler-Weber-Rendu disease.
