Effect of stent placement on stone recurrence and post-procedural cholangitis after endoscopic removal of common bile duct stones

Abstract Background/Aims: After endoscopic treatment of common bile duct (CBD) stones, recurrence of choledocholithiasis due to small stone fragments and post-endoscopic retrograde cholangiopancreatography (post-ERCP) cholangitis can occur. We determined the effect of biliary stenting after removal of CBD stones on the recurrence of CBD stones and the incidence of post-ERCP cholangitis. Methods: We performed a retrospective single-center study involving 483 patients who underwent ERCP for the removal of CBD stones. The patients were classified into two groups according to their
