Summary
A new wire-guided basket simplifies endoscopic bile duct stone removal, especially for deep or multiple intrahepatic stones. This device facilitates easier re-engagement for successful extraction in challenging cases.
Area of Science:
- Gastroenterology
- Endoscopic procedures
- Biliary tract interventions
Background:
- Conventional endoscopic stone retrieval baskets face challenges with deep or tortuous intrahepatic ducts.
- Difficulties arise in accessing and removing stones from segmental bile ducts.
Observation:
- A novel wire-guided basket with a separate guidewire lumen was developed.
- This device allows for rail-loading and advancement over a guidewire into specific ductal segments.
Findings:
- The wire-guided basket was successfully used in three patients with intrahepatic stones.
- It enabled repeated, easy passage to desired locations for stone extraction, even with multiple stones.
- All stones were successfully removed using this new device.
Implications:
- The wire-guided basket is a valuable tool for endoscopic bile duct stone extraction.
- It offers improved efficacy in cases of multiple or difficult-to-reach intrahepatic stones.
- This technology enhances the success rate of endoscopic retrograde cholangiopancreatography (ERCP) procedures.
