Biodegradable internal biliary stenting in orthotopic liver transplantation – A feasibility study

Year: 2024

Type: article

Abstract: Biliary complications remain a common cause of morbidity after liver transplantation and often require invasive interventions to manage. We aimed to assess the technical feasibility and safety of placement of a biodegradable stent across the biliary anastomosis at the time of liver transplantation in patients having a duct to duct biliary reconstruction. For this prospective, single-arm, descriptive study, 10 consecutive patients undergoing whole graft, deceased donor, liver transplantation and duct-to-duct biliary tract reconstruction were enrolled and a biodegradable biliary stent was sutured into the bile duct across the anastomosis. In all 10 patients it was technically feasible to place and secure the stent safely during the operation. After >6 months (median of 212 days) follow up, no patients had developed biliary anastomotic stricture. One patient had transient bile leak immediately post-operative that was managed conservatively. One patient required endoscopic intervention for non-anastomotic stricture development and biliary cast material that had resulted in stent dysfunction. The results of this study suggest surgical feasibility of placement of an absorbable biliary stent across the biliary anastomosis at the time of liver transplantation, as well as an acceptable safety profile. Further studies are required to confirm these safety and feasibility findings and to assess efficacy in reducing rates of biliary complications and the need for endoscopic intervention in the early post-transplant period.
