Summary

Electrohydraulic lithotripsy effectively disintegrates difficult-to-remove biliary stones. This technique offers a valuable addition to choledochoscopy for biliary stone extraction, with minimal complications.

Area of Science:

  • Gastroenterology
  • Endoscopic Surgery

Background:

  • Biliary stone extraction can be challenging using conventional choledochoscopy and basket techniques.
  • Difficulties include impacted stones in various bile duct locations and behind strictures.

Purpose of the Study:

  • To evaluate the efficacy and safety of electrohydraulic lithotripsy for difficult biliary stone removal.

Main Methods:

  • Electrohydraulic lithotripsy was performed on 10 patients with challenging biliary stones.
  • Choledochoscopy and basket extraction were initially attempted but were unsuccessful.

Main Results:

  • All biliary stones were successfully disintegrated and removed using electrohydraulic lithotripsy.
  • The primary complication observed was transient hemorrhage from ductal injury.

Conclusions:

  • Electrohydraulic lithotripsy is a useful adjunct for choledochoscopic removal of complex biliary stones.
  • It provides an effective solution for stones resistant to standard extraction methods.
