Prior to the laparoscopic era cholecystectomy patients with bile duct stones were managed surgically during open cholecystectomy (OC), with direct exploration of their common bile duct (choledochotomy). However, open surgical bile duct exploration waned in popularity and progressively stones were dealt with endoscopically, either pre or post cholecystectomy. As laparoscopic technology advances, simultaneous clearance of the bile duct at the time of laparoscopic cholecystectomy is regaining popularity.
