Late two-stage laparoscopic cholecystectomy is associated with an increased risk of major bile duct injury.

Late laparoscopic cholecystectomy (LC) after endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy (ES) for common bile duct (CBD) stone clearance, two-stage LC (TSLC), is associated with difficult surgical dissection and an increased rate of conversion to open procedure. The purpose of the study was to evaluate whether the interval between ERCP/ES and LC is associated with major bile duct injury (BDI) and determine an optimal period for TSLC.
