Abstract
Purpose: To evaluate the efficacy and safety of percutaneous treatment of biliary strictures complicating orthotopic liver transplantation (OLT). Methods: Between October 1990 and May 2000, 619 patients underwent 678 liver transplants. Seventy of the 619 (11%) patients were found to be affected by biliary strictures by July 2000. Bilioplasty was performed in 51 of these 70 (73%) patients. A cohort of 33 of 51 (65%) patients were clinically followed for more than 12 months after the last percutaneous treatment and included in the survey results. Results: After one to three treatments 24 of 33 (73%) patients were stricture-free on ultrasound and MR cholangiography follow-up. A delayed stricture recurrence required a fourth percutaneous bilioplasty in two of 33 (6%) patients. A surgical bilioenteric anastomosis was performed in six of 33 (18%) patients. Retransplantation was performed due to ischemic damage in one of 33 (3%) patients. Conclusion: Interventional radiology is an effective therapeutic alternative for the treatment of most biliary strictures complicating OLT. It has a high success rate and should be considered before surgical interventions. Elective surgery may be necessary in a few failed cases or those with more severe and extensive biliary strictures.
