Gastric antral angiodysplasia: an unusual cause of occult gastrointestinal bleeding.

A patient with chronic occult gastrointestinal bleeding proved to have multiple gastric antral angiodysplasias and was treated with distal gastric resection. The diagnosis of this lesion is occasionally made endoscopically, since its submucosal nature makes barium contrast studies of no value. Arteriograms will also be helpful in some circumstances. Resection offers the best likelihood for permanent success.
