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

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.Records of 126 patients (average age, 46.1 ± 13.8 years) with cholecystocholedocholithiasis treated with laparoscopic cholecystectomy (LC) and LTCBDE were retrospectively reviewed.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%.Ultrathin choledochoscope and holmium laser lithotripsy can improve the surgical outcomes of LC+LTCBDE with minimal complications.
