This advanced, case-based session explores cholangioscopy for managing complex biliary stones, challenging benign and malignant strictures, and intricate stenting scenarios. Faculty will share tips, tricks, and pitfalls, including retrograde access, cholangioscopic biopsies, lithotripsy, and unique potpourri cases. Elevate your interventional skillset with practical, high-yield pearls, imaging insights, scope handling techniques, complication management strategies, and multidisciplinary approaches to difficult cases across diverse patient populations.

Learning Objectives:

Describe the indications, techniques, and tools used in cholangioscopy-guided management of complex biliary stones.
Demonstrate appropriate strategies for navigating and treating benign and malignant biliary strictures using cholangioscopic visualization and targeted interventions.
Identify common pitfalls, complications, and troubleshooting techniques associated with advanced cholangioscopy, including retrograde access and stent placement.
