Summary
Percutaneous endoscopic stone extraction using a flexible choledochoscope offers a minimally invasive approach for retained common bile duct stones. This technique achieved successful bile duct clearance in all described cases, often in a single session.
Area of Science:
- Gastroenterology
- Surgical Endoscopy
- Biliary Tract Interventions
Background:
- Retained common bile duct stones after exploration are typically managed with fluoroscopic percutaneous extraction or endoscopic sphincterotomy.
- These conventional methods may have limitations or require specialized equipment.
Purpose of the Study:
- To describe the technique and outcomes of percutaneous stone extraction under direct vision using a flexible choledochoscope.
- To evaluate the efficacy and feasibility of this minimally invasive approach.
Main Methods:
- Four cases of retained common bile duct stones were treated using percutaneous extraction under direct vision with a flexible choledochoscope.
- The procedure involved direct visualization for stone removal.
Main Results:
- Complete bile duct clearance was achieved in three out of four cases at a single sitting.
- One case required four sittings for complete stone clearance.
- Follow-up cholangiography confirmed complete clearance in two cases.
Conclusions:
- Percutaneous endoscopic stone extraction with a flexible choledochoscope is an effective minimally invasive treatment for retained common bile duct stones.
- The procedure does not require specialized equipment beyond a flexible choledochoscope and surgeon experience.
- It offers a viable alternative to conventional methods, achieving high clearance rates.
