Core Tip

Core Tip: Common bile duct (CBD) stone recurrence in Billroth II anatomy patients is challenging, and CBD morphology had never been noticed as a potential risk factor for CBD stone recurrence. In this study, CBD morphology was identified to be the independent risk factor for CBD stone recurrence in Billroth II anatomy patients. S type and polyline type were associated with an increased risk of recurrent CBD stones. Periodic surveillance and prophylactic therapy is recommended for Billroth II anatomy patients with S type and polyline type after successful endoscopic retrograde cholangiopancreatography.
