Long-Term Outcome of Patients With Gastrointestinal Bleeding of Obscure Origin Explored by Push Enteroscopy

Abstract

Recurrent bleeding occurs in about one-third of patients who undergo investigation by push enteroscopy for gastrointestinal bleeding of obscure origin, with a trend towards more frequent rebleeding in patients with arteriovenous malformations. Frequent previous bleeding episodes and transfusion requirements are predictive of recurrent bleeding.
