Summary

Biliary strictures after liver transplantation are linked to prolonged cold ischemia times and pre-transplant conditions. Percutaneous balloon dilation offers a useful, minimally invasive treatment option for these strictures.

Area of Science:

  • Hepatology
  • Transplant Surgery
  • Gastroenterology

Background:

  • Biliary strictures are a known complication following liver transplantation.
  • Identifying risk factors and effective treatments is crucial for improving patient outcomes.

Purpose of the Study:

  • To investigate the incidence and characteristics of biliary strictures after liver transplantation.
  • To identify associations between biliary strictures and pre-transplant factors, rejection, and ischemia times.
  • To evaluate the efficacy of percutaneous balloon dilation for treating biliary strictures.

Main Methods:

  • Retrospective analysis of 198 liver transplantations performed between August 1985 and December 1990.
  • Categorization of biliary strictures into anastomotic, nonanastomotic central hilar, and nonanastomotic peripheral.

  • Tabulation of pretransplant disease, hepatic artery patency, rejection status, and donor cold ischemia times.
  • Evaluation of percutaneous balloon dilation outcomes in patients with biliary strictures.

    • Main Results:

    • Twenty biliary strictures were identified in 18 patients.
    • Nonanastomotic strictures were associated with prolonged donor cold ischemia time (mean 9.75 vs. 8.1 hours).
    • Peripheral nonanastomotic strictures were linked to pretransplant sclerosing cholangitis.
    • Nonanastomotic strictures were associated with chronic rejection.
    • Percutaneous balloon dilation was successful in 4 of 13 treated patients, with only one requiring surgery among the failures.

    Conclusions:

    • Nonanastomotic biliary strictures in liver transplant recipients are associated with prolonged donor cold ischemia time, pretransplant sclerosing cholangitis, and chronic rejection.
    • Percutaneous balloon dilation is a potentially effective treatment for biliary strictures in liver transplant patients.
