Efficacy of endoscopic ultrasound after removal of common bile duct stone.
Objective: Endoscopic retrograde cholangiopancreatography (ERCP) is a standard procedure for choledocholithiasis. Nonetheless, the recurrence rate remains quite high. This study aimed to investigate the prevalence and related factors of remnant biliary stone or sludge using endoscopic ultrasound (EUS) after the removal of common bile duct (CBD) stone and to evaluate the long-term clinical outcomes. ⋯ Conclusions: Acute angulation of the distal CBD was associated with remnant biliary stone or sludge after ERCP. Remnant biliary sludge on EUS and large CBD diameter were strong predictors of symptomatic recurrence. EUS evaluation following CBD stone removal could be an effective strategy in the treatment of choledocholithiasis.
