Recent advances of biliary stent management

Area of Science:

• Gastroenterology and Hepatology
• Interventional Endoscopy
• Oncology

Background:

• Prolonged survival in malignant biliary strictures increases stent occlusion rates.
• Covered metallic stents (CMS) are increasingly used but still occlude in approximately 50% of patients.
• Understanding complications and patency rates for CMS removal is crucial for patient management.

Purpose of the Study:

• To investigate the complication and patency rates associated with the removal of covered metallic stents.
• To compare the efficacy of CMS versus uncovered metallic stents in malignant biliary obstruction.
• To evaluate the impact of stent choice on patient quality of life.

Main Methods:

• Retrospective analysis of patients with malignant biliary obstruction treated with covered metallic stents.
• Assessment of complication rates during stent removal procedures.
• Evaluation of patency durations for both initial stent placement and subsequent re-interventions.

Main Results:

• Durations for initial stent placement and re-intervention with CMS were found to be similar.
• Covered metallic stents demonstrated the longest patency durations compared to other options.
• Complication rates for CMS removal were assessed.

Conclusions:

• Covered metallic stents are recommended for malignant biliary obstruction due to their removability and extended patency.
• CMS contribute to preserving patient quality of life.
• Despite similar patency durations to uncovered metallic stents, CMS offer advantages in management.
