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.

In patients with ABS after OLT, the use of Am-FCSEMSs significantly decreased the risk of stent migration, improved stricture resolution at the time of stent removal and reduced the rate of stricture recurrence during follow-up. Endoscopic removal success and procedure-related morbidity were similar for both standard and anti-migration stents.
