ABSTRACT

Objective To discuss the value of intraoperative transnasal cholangiography in endoscopic sphincterotomy(EST) combined with laparoscopic cholecystectomy(LC) for treating cholelithiasis complicated with choledocholithiasis.Methods The EST was carried out to treat common bile duct stones and to conduct the endoscopic nasobiliary drainage(ENBD).During the LC the cholangiography was performed by way of ENBD.Results Intraoperative cholangiography was successfully completed in all 46 cases,with a cholangiography time of 5~15 min(mean,8.2 min).Secondary common duct stones migrated from the gallbladder were found by cholangiography in 4 cases,in 2 of which the stones were removed under endoscope during the procedure,and in 2 of which the stones were
