The role of capsule endoscopy in acute gastrointestinal bleeding

Abstract

Acute gastrointestinal (GI) bleeding is a common cause of hospitalization, resulting in about 400,000 hospital admissions annually, with a mortality rate of 5–10%. It is estimated that 5% of acute GI bleedings are of obscure origin with a normal esophagogastroduodenoscopy and ileocolonoscopy. Capsule endoscopy is the state-of-the-art procedure for inspection of the entire small bowel with a high sensitivity for the detection of causes of bleeding. In recent years, many studies have addressed the sensitivity and outcome of capsule-endoscopy procedures in patients with acute GI bleeding. This review looks at the role of capsule endoscopy in the evaluation of patients with acute GI bleeding from either the upper GI tract or small bowel. © 2013, Sage Publications. All rights reserved.
