Core Tip

Core tip: The potential causes of the recurrence of choledocholithiasis after endoscopic retrograde cholangiopancreatography (ERCP) are unclear. By a large sample sized retrospective study of 954 patients, we concluded that patient age greater than 65 years is an independent risk factor for the development of recurrent choledocholithiasis following ERCP, as is history of biliary surgeries, measures during ERCP, and prevention of postoperative complications.
