Clinical efficacy of anti-migration features in fully covered metallic stents for anastomotic biliary strictures after liver transplantation: comparison of conventional 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.
