Clinical efficacy of anti-migration features in fully covered self-expandable metallic stents for anastomotic biliary strictures after liver transplantation: comparison of standard and anti-migration stents

Anastomotic biliary strictures (ABSs) are one of the most frequent adverse events that occur after orthotopic liver transplantation (OLT). Multiple plastic stents (MPSs) have been validated for this indication. More recently, fully covered self-expandable metallic stents (FCSEMSs) have been used with positive outcomes, but also have a higher rate of migration, which may limit success. Our primary objective was to compare stent migration rates observed with "standard" FCSEMSs (Std-FCSEMSs) and so-called "anti-migration" FCSEMSs (Am-FCSEMSs), which are newly designed with reversed proximal side flaps.
