    Abstract:
    BACKGROUND AND AIMS: Endoscopic treatment is effective in the treatment of patients with bile duct injury after cholecystectomy. We aimed to investigate the long-term results of endoscopic treatment, factors predicting the recurrence of the stricture, and to determine the optimal endoscopic treatment. METHODS: The study was a retrospective cohort analysis and conducted at a tertiary referral center in patients with major bile duct injury (Strasberg E1-4 and E5 patients with main bile duct injury). Patients with minor injury (Luschka and cystic duct leakage), complete transection, and isolated aberrant bile duct injuries were excluded. RESULTS: The study group included 156 patients. The median follow-up period after stent removal was 6.5 years (range 1-16.5). Recurrence was seen in 18 patients (11 %) after a median duration of 9 months (range 2-96). Multivariate regression analysis revealed that the most important factors predicting the success of endoscopic treatment were: Rome type of treatment (inserting increasing number of stents every 3-4 months) (odds ratio 23.8, 95 % CI 1.46-390.7, p = 0.026) instead of Amsterdam-type treatment (replacing two 10F biliary stents every 3-4 months) and dilation of the stricture diameter to at least 76 % of the common bile duct diameter at the end of stent treatment (odds ratio 25.9, 95 % CI 2.46-272.7, p = 0.007). CONCLUSIONS: Endoscopic treatment is an effective method in the treatment of patients with bile duct stricture after cholecystectomy. Inserting multiple stents as much as possible without leaving a scar in the bile ducts should be aimed.
