Feasibility and safety of choledochotomy primary closure in laparoscopic common bile duct exploration without biliary drainage: a retrospective study.

Common bile duct (CBD) exploration and T-tube drainage are the main surgical methods for the removal of bile duct stones (BDSs), which can now be completed by laparoscopy. However, the feasibility and safety of primary closure of the CBD (PCCBD) in laparoscopic CBD exploration (LCBDE) without biliary drainage are still uncertain. From January 1, 2021, to June 30, 2022, patients who were diagnosed with BDSs and underwent LCBDE and primary closure of the CBD without biliary drainage in our hospital were included. The clinical and prognostic data of the patients were retrospectively analyzed to determine the feasibility and safety of PCCBD in LCBDE without biliary drainage. Forty-nine patients successfully underwent PCCBD in LCBDE without biliary drainage. The operation time was 158.8 ± 50.3 (90-315,150) minutes, the bile duct suture time was 17.6 ± 4.46 (10-26, 18) minutes, the intraoperative blood loss volume was 70.4 ± 52.6 (5-200, 80) ml, the hospitalization cost was 28,141.2 ± 7011.3 (15,005.45-52,959.34, 26,815.14) CNY Yuan, the hospitalization time was 13.22 ± 5.16 (8-32, 12) days, and the postoperative hospitalization time was 7.31 ± 1.94 (3-15, 7) days. There were 3 cases of postoperative bile leakage (3/49, 6.12%), all of them healed by nonsurgical treatment. During the follow-up of 17.2 ± 11.01 (10-26, 17) months, no residual BDSs, biliary stricture or other complications classified as Clavien-Dindo grade I or higher occurred. For some selected patients who meet certain criteria, PCCBD in LCBDE without biliary drainage is feasible and safe and is more conducive to the rapid postoperative recovery of patients.
