Self-expandable Metallic Stent Versus Multiple Plastic Stents in Post Orthotopic Liver Transplantation Biliary Stenosis

Patients with biliary stricture after OLT will be randomly assigned following simple randomization to temporary placement of fully covered self-expandable metal stent (SEMS) or multiple plastic stents placement were randomized according to a computer generated randomization sequence and allocated in a 1:1 ratio to one of two treatment groups. Final success will be defined as clinical resolution of the stricture without the need to repeat endoscopic, percutaneous or surgical treatment.
