Cracking Difficult Biliary Stones.

Area of Science:

• Gastroenterology
• Endoscopic Procedures
• Biliary Interventions

Background:

• Biliary stone removal is a key challenge during ERCP.
• Standard methods like balloons and baskets are insufficient for large or impacted stones.
• Mechanical lithotripsy was previously the primary option for difficult stones.

Purpose of the Study:

• To review current strategies for managing difficult common bile duct (CBD) stones during ERCP.
• To highlight the efficacy of endoscopic papillary large balloon dilation (EPLBD) and peroral cholangioscopy (POCS).
• To assess the role of these advanced techniques in improving procedural success and efficiency.

Main Methods:

• Review of current literature on ERCP stone removal techniques.
• Discussion of endoscopic papillary large balloon dilation (EPLBD) for large CBD stones (up to 1.5 cm).
• Evaluation of peroral cholangioscopy (POCS) with probe-based lithotripsy (electrohydraulic or laser) for complex cases.

Main Results:

• EPLBD is the gold standard for large CBD stones, reducing procedure time and device costs.
• POCS with lithotripsy facilitates management of very large, impacted, or intrahepatic stones.
• These advanced techniques demonstrate high success rates with minimal complications.

Conclusions:

• EPLBD and POCS-assisted lithotripsy are crucial advancements in ERCP for difficult biliary stone removal.
• These methods improve efficiency, reduce costs, and offer high success rates for challenging stone burdens.
• Further adoption of these techniques can enhance patient outcomes in biliary interventions.
