Endoscopic management of malignant biliary obstructions.

Area of Science:

• Gastroenterology
• Interventional Endoscopy
• Oncology

Background:

• Malignant biliary obstruction (MBO) is common, frequently unresectable at diagnosis.
• Neoadjuvant chemotherapy is increasingly used, necessitating biliary drainage.
• Endoscopic biliary drainage is a key intervention for MBO management.

Purpose of the Study:

• To review the current evidence for endoscopic management of distal and hilar MBO.
• To highlight the role of interventional endoscopic ultrasound (EUS) in biliary drainage.
• To discuss current hot topics in the endoscopic treatment of MBO.

Main Methods:

• Comprehensive literature review of endoscopic biliary drainage techniques.
• Focus on EUS-guided biliary drainage, transpapillary drainage, and percutaneous approaches.
• Evidence-based analysis of current practices and emerging trends.

Main Results:

• EUS-guided biliary drainage has gained significant acceptance.
• Endoscopic techniques are vital for managing MBO, especially when unresectable.
• Various endoscopic and percutaneous approaches are available for biliary drainage.

Conclusions:

• Endoscopic interventions, particularly EUS-guided drainage, are crucial for managing MBO.
• The review provides an evidence-based overview of current endoscopic roles and future directions.
• Optimal management strategies for MBO involve a multidisciplinary approach considering drainage options.
