Abstract:Objective To investigate the use of endoscopic retrograde cholangiopancreatography (ERCP) combined with laparoscopic cholecystectomy (LC) one-stage approach in the treatment of gallstones complicated with calculus of common bile duct in a hybrid operating room.Methods 21 patients with gallstones complicated with calculus of common bile duct were selected to undergoing ERCP bile duct stone removal under total intravenous anesthesia or combined intravenous and inhalation anesthesia, followed by LC.Results 18 successfully completed the one-stage surgery of ERCP combined with LC, 3 were changed to laparoscopic common bile duct exploration (LCBDE), there was no laparotomy, 8 cases were complicated by hyperamylemia after surgery, and there were no serious complications such as pancreatitis, gastrointestinal bleeding and perforation.Conclusion It is safe and feasible to use ERCP combined with LC one-stage approach to treat gallstones complicated with calculus of common bile duct in the hybrid operating room, which simplifies the surgical process.
