Intraoperative cholangiography facilitates simple transcystic clearance of ductal stones in units without expertise for laparoscopic bile duct surgery

摘要

In the absence of facilities and expertise for laparoscopic bile duct exploration (LBDE), most patients with suspected ductal calculi undergo preoperative endoscopic duct clearance. Intraoperative cholangiography (IOC) is not performed at the subsequent laparoscopic cholecystectomy. This study aimed to investigate the rate of successful duct clearance after simple transcystic manipulations.
