Abstract

A variety of diagnostic modalities is available to assist in the evaluation of patients presenting with acute gastrointestinal (GI) bleeding. This article reviews some older technologies like colonoscopy, nuclear scintigraphy, and conventional angiography and will also review the newest additions to the lower GI bleeding diagnostic toolbox, which are video capsule endoscopy and computed tomography (CT) angiography. The management algorithm used at a given institution depends on the available expertise and resources.
