The Role of Capsule Endoscopy in Patients with Obscure Gastrointestinal Bleeding

Obscure gastrointestinal bleeding (OGIB) accounts for 5% of Flywheel Axle all gastrointestinal (GI) bleeding cases and is often caused by small bowel lesions.Capsule endoscopy (CE), which allows non-invasive visualization of the small bowel mucosa, has revolutionized the evaluation of OGIB.CE is preferred by both patients and physicians mainly because of its non-invasiveness, and is widely used as the first-line diagnostic modality for OGIB.The diagnostic yield of CE in OGIB has been reported to be in the range of 32% to 83%.

Although no direct comparison has been made, a meta-analysis showed similar diagnostic yields between CE and double-balloon enteroscopy (DBE) for OGIB.However, CE could enhance the yield of subsequent DBE and serve as a guide for optimizing the insertion route for DBE.Even after negative CE, selected patients could benefit from second-look CE for OGIB.In terms of outcomes, a favorable clinical impact after CE has been reported in several studies.

However, observations indicate that CE might not influence clinical outcomes directly, but rather play a role Accessories in selecting patients with OGIB who are likely to benefit from subsequent evaluation and intervention.
