Cumulative incidence of retained common bile duct stones on postoperative endoscopic retrograde cholangiopancreatography Active intervention versus surveillance per common bile duct (CBD) stone size. IOC, intraoperative cholangiography; ECRP, endoscopic retrograde cholangiopancreatography.

Video: Intervention versus surveillance in patients with common bile duct stones detected by intraoperative cholangiography

Each year 13 000 patients undergo cholecystectomy in Sweden, and routine intraoperative cholangiography (IOC) is recommended to minimize bile duct injuries. IOC plus an intervention to remove CBD stones identified during cholecystectomy was associated with reduced risk for retained stones and unplanned ERCP, even for the smallest asymptomatic CBD stones in this BJS study.
