Percutaneous Transhepatic Biodegradable Biliary Stent Placement for Benign Biliary Strictures

Abstract

This article aimed to assess the safety and effectiveness of biodegradable stents in the management of benign biliary strictures. This is a retrospective observational study that included all adult patients who had biodegradable stent placement for a benign cause of biliary stricture between July 2016 and August 2019. Nineteen patients were included. Seventeen patients had liver transplant. One patient had hepaticojejunostomy due to primary sclerosing cholangitis and one patient had iatrogenic left main bile duct occlusion. Stents were successfully deployed in all 19 patients (technical success: 100%). Patency rate was 90% (17/19) at 6 months and 80% (12/15) at 12 months. Seven patients in the study had stricture recurrence and needed reintervention with mean time to reintervention of 418 days (range: 8–1,155 days). There was one major complication due to cholangitis and sepsis, which required a treatment course with piperacillin/tazobactam for 10 days. No procedure-related pancreatitis or deaths occurred. Biodegradable stents are a safe and effective treatment option for benign biliary strictures and can achieve long-term patency without the need for reinterventions.
