Benign postoperative biliary strictures: dilation with fluoroscopic guidance.

H J Williams, C E Bender, G R May

    Summary

    Percutaneous balloon dilation effectively treats benign postoperative biliary strictures, achieving a 78% success rate. Transhepatic dilation carries risks, while T-tube track dilation is safer and preferred when possible.

    Area of Science:

    • Interventional Radiology
    • Gastroenterology
    • Hepatobiliary Surgery

    Background:

    • Benign postoperative biliary strictures can complicate hepatobiliary surgery.
    • These strictures may lead to significant morbidity if not adequately managed.
    • Percutaneous balloon dilation offers a minimally invasive treatment option.

    Purpose of the Study:

    • To evaluate the efficacy and safety of percutaneous balloon dilation for benign postoperative biliary strictures.
    • To identify factors influencing successful stricture dilation and patency.
    • To compare complication rates between different dilation approaches.

    Main Methods:

    • Seventy-four patients with benign postoperative biliary strictures underwent percutaneous balloon dilation.
    • Dilation was performed under fluoroscopic guidance.

  • Two primary routes were assessed: transhepatic and via a T-tube track.

    • Main Results:

    • Overall success rate for lasting patency was 78%.
    • Success rates were higher for primary ductal strictures (88%) than biliary-enteric anastomotic strictures (73%).
    • Longer intervals (>2 years) between surgery and dilation correlated with better outcomes. Transhepatic dilation resulted in serious complications (sepsis, bleeding), unlike T-tube track dilation.

    Conclusions:

    • Percutaneous balloon dilation is an effective treatment for benign postoperative biliary strictures, especially when surgical repair is challenging.
    • Dilation via a T-tube track is the preferred and safer route.
    • Early consideration of T-tube placement may facilitate future dilation if strictures develop.
