Biliary self-expandable metal stents (SEMS), a group of non-vascular stents, have
been used in the palliative management of biliary obstruction around the world.
However, there are still unmet needs in the clinical application of biliary SEMS.
Comprehensive understanding of the SEMS is required to resolve the drawbacks and
difficulties of metal stent development. The basic structure of SEMS, including
the materials and knitting methods of metal wires, covering materials, and
radiopaque markers, are discussed in this review. What we know about the physical
and mechanical properties of the SEMS is very important. With an understanding of
the basic knowledge of metal stents, hurdles such as stent occlusion, migration,
and kinking can be overcome to develop more ideal SEMS.
