Bleeding Lesion of the Small Bowel: an Extensive Update Leaving No Stone Unturned

Curr Gastroenterol Rep. 2018 Mar 7;20(2):5. doi: 10.1007/s11894-018-0610-4.

Abstract

Purpose of review: Gastrointestinal bleeding originating from the small bowel (SB) poses a challenge to the treating gastroenterologist. Once diagnosed, management is not a walk in the park either. This review intends to summarize the current state-of-the-art evidence in a complete way with special attention for vascular and ulcerative lesions, to provide the reader with a clinical guide and flow chart towards SB bleeding.

Recent findings: Absence of SB bleeding lesions on CE does not directly yield better prognosis; although having a lower rebleeding rate the first 2 years, rebleeding in the long term is high. Push enteroscopy can play an early role in patients with SB bleeding if suspicion of angioectasia is high, since these lesions tend to be located in the proximal SB. Endoscopic management of angioectasia is, however, difficult and shows poor results. Capsule endoscopy (CE) or device-assisted enteroscopy (DAE) remain the diagnostic mainstay in SB bleeding, choosing one over the other based upon patient characteristics and expected lesions.

Keywords: Capsule endoscopy; Endoscopic treatment; Gastrointestinal bleeding; Midgut bleeding; Small bowel; Small bowel imaging.
