Abstract

Gastric angiodysplasia is an uncommon cause of upper gastrointestinal blood loss that may occur in the stomach or duodenum, and is responsible for up to 1∼6% of upper gastrointestinal bleeding. In contrast to colonic angioectasia, gastric lesions are more common in young individuals and originate from developmental causes. On an endoscopic examination, the lesions typically show a spider-shape or coral reef-like pattern of dilated and tortuous vessels and measure approximately 2 to 10 mm in diameter. We encountered a case of huge gastric angiodysplasia that presented with overt bleeding and anemia and was successfully treated with argon plasma coagulation.
