Title: Long-Term Efficacy of Percutaneous Internal Plastic Stent Placement for Non-anastomotic Biliary Stenosis After Liver Transplantation

Abstract

PurposeWe aimed to evaluate the long-term efficacy of percutaneous management of non-anastomotic biliary stenosis after liver transplantation, using plastic internal biliary stents.Materials and MethodsThis study included 35 cases (28 men, 7 women; mean age: 52.09 ± 8.13 years, range 34–68) in 33 patients who needed repeated interventional procedures because of biliary strictures. After classification of the biliary strictures, we inserted percutaneous biliary plastic stents through the T-tube or percutaneous transhepatic biliary drainage tracts. Stents were exchanged according to percutaneous methods at regular 2- to 6-month intervals. The stents were removed if the condition improved, as observed on cholangiogram as well as based on clinical findings. The median patient follow-up period after initial diagnosis and treatment was 6.04 years (range 0.29–9.95 years). We assessed treatment success rate and patient and graft survival times.ResultsDuring the follow-up period, 14 patients (14/33, 42.42 %) were successfully treated and were tube-free. The median tube-free time, time without a stent, was 4.13 years (range 1.00–9.01). In contrast, internal plastic stents remained in 9 patients (9/33, 27.27 %) until the last follow-up. These patients had acceptable hepatic function. Among the remaining 10 patients, 3 (3/33, 9.09 %) were lost to regular follow-up and the other 7 (7/33, 21.21 %) patients died. The overall graft loss rate wasmore » 20.0 % (7/35). The median time from initial treatment to graft loss was 1.84 years (range 0.42–4.25).ConclusionsPercutaneous plastic stents placement is technically feasible and clinically useful in patients with multiple biliary stenoses following liver transplantation.« less
