Abstract:
Objective To evaluate the efficacy of the suspended overlength biliary stents modified from nasobiliary tube for prevention of duodenobiliary reflux. Methods Suspended overlength biliary stents were placed in the intrahepatic bile duct of 18 patients with extrahepatic bile duct stricture who underwent biliary stents implantation once or more via ERCP from February 2014 to May 2016.Data of these patients were followed up to June 30, 2017 with self-control method. The patency time of suspended overlength biliary stents was compared with the ordinary biliary stents which were implanted in the last ERCP. Incidence of complications was recorded.Results Eighteen patients were enrolled in the study, but one patient lost follow-up. Finally 17 patients were enrolled in the analysis. Nine patients were malignant and 8 benign biliary stricture. The median patency time of suspended overlength biliary stents was 210 days, which was much longer than that of ordinary stents with median patency time of 139 days(P＝0. 015). The median patency time of overlength biliary stents and metal stents in 3 patients with malignant stricture were 278 days and 205 days (P＝1. 000). The median patency time of overlength biliary stents and traditional plastic stents in 6 patients with malignant stricture were 156 days and 65 days, respectively(P＝0. 049). The median patency time of this innovative stents was prolonged in benign biliary stricture patients (254 days VS 143 days, P＝0. 025). Only one patient developed mild pancreatitis after ERCP. Conclusion Suspended overlength biliary stents can prolong the patency time without increasing postoperative complications, which is worth popularization.
