Endoscopic lithotripsy in the common bile duct

H Koch, W Rösch, V Walz

    Gastrointestinal Endoscopy
    |February 1, 1980
    PubMed
    Summary

    Electrohydraulic lithotripsy successfully shattered common bile duct stones using an integrated Dormia basket. This method aids in removing stones resistant to traditional endoscopic procedures.

    Area of Science:

    • Gastroenterology
    • Endourology
    • Medical Devices

    Background:

    • Common bile duct stones pose a significant clinical challenge.
    • Endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy is a primary treatment.
    • Some stones remain impacted, necessitating alternative removal techniques.

    Purpose of the Study:

    • To evaluate the efficacy of electrohydraulic lithotripsy for impacted common bile duct stones.
    • To assess the integration of lithotripsy with Dormia basket for stone fragmentation.

    Main Methods:

    • Electrohydraulic lithotripsy probe was coupled with a Dormia basket.
    • Procedure performed on human patients with impacted common bile duct stones.
    • Successful fragmentation required firm lodging of the stone within the basket.

    Main Results:

    • Electrohydraulic lithotripsy was successfully performed on common bile duct stones.
    • The integrated Dormia basket facilitated stone fragmentation.
    • This technique enabled the removal of stones previously resistant to endoscopic papillotomy.

    Conclusions:

    • Electrohydraulic lithotripsy, when combined with a Dormia basket, offers a viable solution for impacted common bile duct stones.
    • This approach expands treatment options for challenging gallstone cases.
    • Firm stone impaction within the basket is crucial for successful fragmentation.
