Fig. 1From: Dilation of the cystic duct confluence in laparoscopic common bile duct exploration and stone extraction in patients with secondary choledocholithiasisDetailed surgery flow diagram. Among 191 patients with cholelithiasis and secondary choledocholithiasis, CBD stones were successfully extracted through the cystic duct and confluence with the choledochoscope in 9 patients, while 68 patients received LTD-CBDE (dotted box) and 114 patients received LCBDE. CBD, common bile duct; LCBDE: laparoscopic CBD exploration with choledocotomy followed by laparoscopic cholecystectomy; LTD-CBDE: laparoscopic transcystic approach by dilating the cystic duct confluence in CBD exploration.
