BACKGROUND: Angiodysplasia is a distinct mucosal vascular lesion associated with acute or chronic gastrointestinal bleeding. It occurs most frequently in the right colon and is extremely rare. Its etiology is unknown, but theories of its pathogenesis have evolved from its similarity to colonic angiodysplasia and the lesion appears to be associated with renal insufficiency. CASE REPORT: Sixty-five-year-old woman with repeated melena and severe anemia due to angiodysplasia in the first portion of the duodenum. The diagnosis was done by upper endoscopy. As the patient presented repeated gastrointestinal bleeding with hemodynamic instability and recurrent anemia, surgery was indicated. At laparotomy the lesion was identified and resected with an Y-en-Roux reconstruction. The patient went on well at the immediate and late (four years) postoperative periods with no more recurrent gastrointestinal bleeding. CONCLUSION: Although most of the patients suffering from gastrointestinal angiodysplasia goes on well with conservative management, there is a small portion of them that will need a more aggressive approach, as in this case.
