Laparoscopic treatment of gallbladder and common bile duct stones: A prospective study

The aim of this study was to investigate prospectively the feasibility, success rate, safety, and short-term results of single-stage laparoscopic treatment of gallstones and ductal stones in 100 consecutive, unselected patients. Common bile duct (CBD) stones were diagnosed at routine intraoperative cholangiography and choledochoscopy in 100 of 950 patients with gallstones undergoing laparoscopic cholecystectomy (LC), Unsuspected CBD stones were present in 39 patients (4.1% of 950; 39% of 100); 26 patients were referred for surgery after failed endoscopic sphinctertomy (ES) performed elsewhere, Transcystic duct CBD exploration (TC-CBDE) was the procedure of choice. When it was not feasible, choledochotomy and direct CBD exploration (D-CBDE) was performed. Use of biliary drainage was liberal, ri completion cholangiogram was obtained for all patients. Laparoscopic treatment of CBD stones was successful in 96 patients: after TC-CBDE in 63 and after D-CBDE in 33, Four operations were converted to open surgery (4%). Retained stones, observed in five patients, were treated by ES in two cases and by percutaneous endoscopic/fluoroscopic lithotripsy in three, Minor morbidity included biloma (n = 2), port site infection (n = 2), and subumbilical hematoma (n = 1). Major morbidity was bile leakage from the cystic duct stump in two cases due to clips or transcystic duct drainage displacement, respectively. One elderly, high risk patient died after being referred for several failed attempts of endoscopic clearance; she died from cardiogenic shock 3 days after successful laparoscopic treatment. Laparoscopic CBD exploration is feasible and safe in most patients, with short-term results that compare favorably with the results of sequential ES/LC reported in the literature.
