title: Angiodysplasia of the stomach and duodenum.
abstract: Twenty-five angiodysplasias in the stomach and duodenum were identified with endoscopy in 12 patients. The average age of the patients was 70 years. Two patients had aortic stenosis. Six of the patients were treated with electrocoagulation, three of whom required surgery. Angiodysplasia of the upper gastrointestinal tract is considered to be more common than previously thought and an important cause of both obscure and overt bleeding.
