Management of anastomotic biliary stricture after liver transplantation: metal versus plastic stent.

Background: Post-transplant anastomotic biliary strictures remain refractory to endoscopic therapy in a considerable number of cases. The aim of this meta-analysis was to compare fully-covered self-expandable metal and plastic stents in the management of post-transplant biliary strictures.

Methods: A meta-analysis was performed using a random effects model; results were expressed as odds ratio (OR) and mean standardized difference.
