IDDF2020-ABS-0097 Study on the influencing factors of ERCP treatment of benign biliary stricture recurrence

Background To investigate the influencing factors of benign biliary stricture recurrence after ERCP treatment. Methods A total of 100 patients of biliary stenosis with endoscopic biliary stent implantation from February 2017 to March 2020 were enrolled in our study. Patients were divided into the recurrence group and recurrence group according to incision re-stenosing within one year after removing the stents. The influencing factors of postoperative recurrence were compared between the two groups. Results Hilar biliary stricture, common bile duct incision + T-tube drainage, length of bile duct stenosis, and proximal dilation of biliary stricture were important high-risk factors for benign biliary stricture recurrence after endoscopic biliary stent placement (P Conclusions There are various factors that affect the recurrence of benign biliary stricture after ERCP treatment. It helped reduce the recurrence rate through risk factors intervention.
