Background And AimsEndoscopic 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.MethodsThe 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.ResultsThe 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).ConclusionsEndoscopic 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.
