    Area of Science:

    • Interventional Radiology
    • Gastroenterology
    • Palliative Care

    Background:

    • Obstructive jaundice due to malignancy significantly impacts patient quality of life.
    • Palliative interventions are crucial for managing malignant biliary obstruction.
    • Transhepatic endoprosthesis insertion is a potential treatment modality.

    Purpose of the Study:

    • To evaluate the efficacy and safety of transhepatic biliary endoprosthesis insertion.
    • To assess procedural outcomes and complication rates.
    • To determine the palliative benefit in patients with malignant biliary obstruction.

    Main Methods:

    • A two-step transhepatic procedure for biliary endoprosthesis insertion was performed in 162 patients.
    • Different materials (Teflon, polyethylene, Percuflex, polyurethane) were used.
    • Patient outcomes, including mortality and complications, were recorded.

    Main Results:

    • The procedure-related mortality rate was 3.7%, with 9% experiencing postprocedural complications.
    • Delayed complications included cholangitis (20%), obstruction (6%), and dislocation (3%).
    • The mean survival time for all patients was 20 weeks.

    Conclusions:

    • Transhepatic biliary endoprosthesis insertion is an effective palliative treatment for malignant obstructive jaundice.
    • The procedure carries specific risks and potential delayed complications that require monitoring.
    • Material choice may influence long-term outcomes, with newer materials showing promise.
