The efficacy and safety of laparoscopic common bile duct exploration with primary duct closure for cholecystolithiasis combined with choledocholithiasis

Abstract Cholecystolithiasis combined with choledocholithiasis represents a prevalent disease. At present, regarding the management of the common bile duct (CBD), T‐tube drainage (TTD) and primary duct closure (PDC) emerge as two prominent approaches for biliary tract repair after laparoscopic CBD exploration (LCBDE).
