Area of Science:

Biomedical Engineering
Gastroenterology
Materials Science

Background:

Biliary self-expandable metal stents (SEMS) are widely used for palliative management of biliary obstruction.
Current clinical applications of biliary SEMS face unmet needs and challenges.
A deeper understanding of SEMS is essential for improving their design and efficacy.

Purpose of the Study:

To provide a comprehensive review of biliary SEMS.
To discuss the basic structure, materials, and properties of SEMS.
To identify key areas for future development to overcome current limitations.

Main Methods:

Review of existing literature on biliary SEMS.
Analysis of SEMS structure, including materials, knitting methods, covering, and radiopaque markers.
Discussion of physical and mechanical properties of SEMS.

Main Results:

SEMS are composed of metal wires, covering materials, and radiopaque markers.
Physical and mechanical properties are critical for SEMS performance.
Understanding these properties is key to addressing issues like stent occlusion, migration, and kinking.

Conclusions:

Further research into SEMS materials and properties is needed.
Addressing structural and mechanical challenges will lead to the development of more ideal biliary SEMS.
Improved SEMS will enhance the palliative management of biliary obstruction.
