Safety and efficacy of small-bowel capsule endoscopy examination in patients with Billroth II gastrojejunostomy.

This retrospective study demonstrates that SBCE is a safe and effective diagnostic tool in patients with Billroth II gastrojejunostomy with a favorable gastroscopic evaluation within 7 days prior. The frequently real-time monitoring is suggested due to the risk of retention in the afferent loop, and a delayed food intake is required when a prolonged stay in the afferent loop occurred.
