Laparoscopic treatment for choledocholithiasis: a prospective evaluation in 247 consecutive unselected patients.
OBJECTIVE
Evaluation of the feasibility and results of the one-stage treatment combining routine intraoperative cholangiography and laparoscopic common bile duct exploration for choledocholithiasis.


METHODS
Multicentric (5 centers-9 surgeons) prospective study in 247 consecutive patients (mean age 68 years; range 21-92) during a 50-month period (November 1991-December 1995). Laparoscopic treatment of choledocholithiasis was attempted irrespective of the circumstances leading to the diagnosis of biliary lithiasis or the preoperative suspicion of choledocholithiasis.


RESULTS
One out of four patients (n = 61) had unsuspected choledocholithiasis disclosed by routine intraoperative cholangiography. A laparoscopic complete clearance of choledocholithiasis was achieved in 208 of 236 attempted cases (88%), with either transcystic duct extraction (n = 116) or choledochotomy (n = 92). Open surgery was required in 20 patients for failure of laparoscopic treatment and in 3 patients despite successful extraction. Twenty-one of 25 patients (84%) referred for failure of retrograde endoscopic stone extraction had successful laparoscopic choledocholithiasis clearance. The mean duration for the laparoscopic transcystic approach and choledochotomy were 108 min (range 50-300) and 173 min (range 70-480), respectively. Eleven patients had retained stones (4.4%). Minor and major complications were recorded in 9 and 22 patients respectively. The operative mortality was 0.4% (95% confidence interval: 0-1.2%).


CONCLUSIONS
Intraoperative cholangiography during laparoscopic cholecystectomy and laparoscopic common bile duct exploration when required should be considered as the simplest and most efficient treatment for choledocholithiasis. The multicenter character of this study including consecutive patients from public and private practices, strengthens our conclusions and is consistent with a wide diffusion of this diagnostic and therapeutic strategy.
