Laparoscopic primary closure of common bile duct combined with percutaneous cholangiographic drainage for treating choledocholithiasis

The aim of this study was to compare the efficacy and safety of laparoscopic primary closure of the common bile duct (CBD) combined with percutaneous transhepatic cholangiographic drainage (PTCD) and laparoscopic choledocholithotomy with T-tube placement for the treatment of CBD stones. Between January 1991 and July 2002, 50 patients with choledocholithiasis and a CBD diameter larger than or equal to 1 cm underwent laparoscopic CBD explorations. The study group consisted of 10 patients undergoing laparoscopic primary closure of the CBD combined with PTCD. The control group consisted of 40 patients undergoing laparoscopic choledocholithotomy with T-tube placement. Parameters were compared statistically. The study group showed higher female/male ratio (6/4 vs 8/32, P = 0.02), less stone numbers (1.90 ± 0.88 vs 3.40 ± 1.65, P = 0.0078), shorter operation time (138 ± 37 minutes vs 191 ± 75 minutes, P ± 0.014), and shorter postoperative stays (7 ± 3 days vs 10 ± 3 days, P = 0.0013). It seems that laparoscopic primary closure of the CBD combined with PTCD can shorten the operation time and postoperative stays as compared with laparoscopic choledocholithotomy with T-tube placement for the treatment of CBD stones.
