Background: Laparoscopic transcystic common bile duct exploration (LTCBDE) is used to treat cholecystolithiasis and choledocholithiasis. This study aimed to investigate the safety, effectiveness and generalisability of LTCBDE in patients with cholecystolithiasis and choledocholithiasis based on our LTCBDE experience within 8 years.
Methods: Four hundred patients with cholecystolithiasis and choledocholithiasis (including 62 of cholecystolithiasis and choledocholithiasis with common bile duct no-dilatation) treated with LTCBDE at a single centre from January 2014 to February 2022 were retrospectively evaluated. They were divided into the first 200 and last 200 LTCBDE cases. The disease characteristics, cystic duct incision methods, surgical outcomes and follow-up data were analysed retrospectively. Each patient was followed up for > 3 months.
Results: Four hundred patients underwent LTCBDE, including 188 males and 212 females aged from 15 to 91 years (average age: 56 years). LTCBDE was successful in 377 (94.3%) patients, while treatment was converted to laparoscopic choledocholithotomy with T-tube drainage in 23 (5.8%), owing to intraoperative choledochoscope insertion failure. The CBD diameter (10.89 ± 1.76 vs 9.97 ± 2.39, P < 0.05), cystic duct diameter (4.62 ± 1.03 vs 5.03 ± 1.29, P < 0.05), and operation time (164.60 ± 24.30 vs 135.34 ± 30.00, P < 0.05). Residual stones were found in six (1.5%) patients and removed during the second operation; post-operative bile leakage was found in one (0.3%) patient, who was discharged safely after the second operation.
Conclusions: Phase I LTCBDE is safe and effective in treating cholecystolithiasis and choledocholithiasis. With continuous technological advances, LTCBDE has been effectively promoted and applied.
