Core Tip
Core tip: We performed a systematic review and meta-analysis comparing the diagnostic accuracy of video capsule endoscopy and double-balloon enteroscopy (DBE) in cases of obscure gastrointestinal bleeding of vascular origin. This is the first systematic review in this setting. We observed that the diagnostic accuracy of detecting small bowel bleeding from a vascular source is increased with the use of an isolated video capsule endoscope compared with isolated DBE. However, concomitant use increases the detection rate of the bleeding source.
