BACKGROUND: There are three choledochotomy closure methods available following laparoscopic common bile duct exploration: T-tube insertion, antegrade stenting, and primary choledochorrhaphy. We reviewed the experience of 12 years at our center searching for the optimal closure technique. METHODS: We analyzed retrospectively 146 patients that underwent one of the three closure methods from February 2004 to March 2016. Hospital stay, need for readmission, incidence of early and long-term complications, and biliary leakage development and their clinical impact were determined for each technique. RESULTS: Hospital stay was more prolonged, and need for readmission was higher in the T-tube group. Nine patients of the T-tube group (17.3%), 5 patients (8.6%) of the antegrade stenting group, and 1 patient of the primary suture group (2.8%) developed Dindo-Clavien ≥3 complications (P = .076). The incidence of biliary leakage was 3.8%, 8.6%, and 16.7% for the T-tube group, antegrade stenting group, and primary suture group, respectively. There was no grade C biliary fistula in the primary suture group, and all grade B leaks in these patients were only due to prolonged duration. The T-tube removal caused adverse events in 21.1% of the patients, and complications directly related with stents occurred in 9.6%. CONCLUSION: Antegrade stents or T-tube insertion do not provide any added value for choledochotomy closure but are charged with specific morbidity. On the contrary, despite biliary leaks being more frequent after primary suture, they are of little clinical consequence and may be managed on an outpatient basis.
