Risk Factors for Single and Multiple Recurrences for Endoscopic Retrograde Cholangiopancreatography and Open Choledochotomy in Treating Choledocholithiasis.

Background: There are few studies comparing recurrences between endoscopic retrograde cholangiopancreatography (ERCP) and open choledochotomy (OCT).

Aims: To compare the effect of different surgical methods on single and multiple recurrences of choledocholithiasis.

Methods: A total of 1255 patients with choledocholithiasis who underwent ERCP or OCT were retrospectively studied.
