Summary
Self-expandable metallic stents (SEMS) offer improved patency for biliary obstruction management. This review covers SEMS characteristics, complications, and guidelines for benign and malignant biliary strictures.
Area of Science:
- Gastroenterology
- Interventional Endoscopy
- Biliary Tract Diseases
Background:
- Biliary stenting has advanced significantly over 30 years.
- Endoscopic stent placement is a primary therapy for biliary obstruction.
- Self-expandable metallic stents (SEMS) offer advantages over plastic stents for malignant strictures.
Purpose of the Study:
- To review the characteristics and complications of SEMS in biliary stenting.
- To discuss current guidelines for managing benign and malignant biliary obstructions.
- To highlight recent developments in biliary stenting.
Main Methods:
- Review of self-expandable metallic stent (SEMS) characteristics.
- Analysis of complications associated with biliary stent placement.
- Examination of current clinical guidelines for biliary obstruction management.
Main Results:
- SEMS provide larger lumens and longer patency compared to plastic stents, particularly for malignant strictures.
- SEMS are increasingly utilized for benign biliary strictures and leaks.
- The review synthesizes information on SEMS, complications, and management guidelines.
Conclusions:
- SEMS represent a significant advancement in biliary stenting for both malignant and benign conditions.
- Understanding SEMS characteristics and potential complications is crucial for effective patient management.
- Ongoing developments continue to refine biliary stenting techniques and outcomes.
