Abstract

The aim of this study was to evaluate the safety and the effectiveness of polydioxanone-made biodegradable biliary stent placement for the treatment of post-transplant benign, refractory biliary anastomotic strictures. This was a retrospective observational study on all adult liver transplant recipients who developed a clinically significant anastomotic stricture between January 2014 and June 2017. Percutaneous transhepatic cholangioplasty with balloon dilation was performed as therapeutic approach in selected patients after multidisciplinary evaluation. Refractory strictures (defined as stricture persistence after two interventional procedures) were managed with placement of polydioxanone-made biodegradable biliary stent (SX-Ella biliary stent, Czech Republic). Patency of the common bile duct was calculated using Kaplan-Meier analysis. Eighteen adult liver transplant recipients who developed a refractory biliary anastomotic stricture [males/females 13/5, median (IQR) 58.2 (9.3) years] underwent biodegradable biliary stent placement after 10.4 (32) months from liver transplantation. All procedures except one were uneventful. After a median (IQR) follow-up time of 27.2 (22) months, complete resolution of anastomotic stricture wa...Continue Reading
