A novel laparoscopic transcystic approach using an ultrathin choledochoscope and holmium laser lithotripsy in the management of cholecystocholedocholithiasis: An appraisal of their safety and efficacy.

Abstract Background Although laparoscopic transcystic common bile duct exploration (LTCBDE) is the preferred approach for CBD stone clearance, the success rate can vary between 55% and 85%. This study evaluated if ultrathin choledochoscope and holmium laser lithotripsy could improve the success rate of LTCBDE. Methods Records of 126 patients (average age, 46.1 ± 13.8 years) with cholecystocholedocholithiasis treated with laparoscopic cholecystectomy (LC) and LTCBDE were retrospectively reviewed. Results LC+LTCBDE was performed successfully in 118 of 126 patients, with a surgical success rate of 93.7%. An ultrathin choledochoscope was used in 75 (63.5%) patients, and holmium lithotripsy was performed in 38 (32.2%) patients. The stone clearance rate was 99.2% (117/118). No significant complications occurred. One hundred (84.7%) patients had excellent and 13 (11%) had good outcomes for an overall success rate (excellent plus good) of 95.7%. Conclusion Ultrathin choledochoscope and holmium laser lithotripsy can improve the surgical outcomes of LC+LTCBDE with minimal complications.
