    This study demonstrates the successful extraction of common duct stones using coagulum pyelolithotomy in dogs and humans. The technique, pioneered by Dees, shows promise for common bile duct stone removal.

    Area of Science:

    • Surgical techniques
    • Gastrointestinal surgery
    • Urology

    Background:

    • Common duct stones can cause significant health issues.
    • Surgical extraction is often necessary.
    • Existing techniques may have limitations.

    Observation:

    • The study utilized coagulum pyelolithotomy, a technique developed by Dees in 1943.
    • A canine model was established using an autogenous clot for pyelolithotomy.
    • The technique was applied to extract common duct stones.

    Findings:

    • Coagulum pyelolithotomy successfully removed common duct stones in 17 dogs.
    • The technique was also effective in three human patients.
    • The canine model accurately replicated the conditions for stone extraction.

    Implications:

    • Dees' coagulum pyelolithotomy technique shows potential applicability in human common bile duct surgery.
    • This method offers a viable alternative for treating choledocholithiasis.
    • Further research may validate its widespread clinical use.
