Aims and objectives
The purposes of this study were to determine the short-term and long-term effectiveness of percutaneous balloon dilation and stenting of postoperative benign biliary strictures,
to assess the effects of interventional procedures on the liver function by means of blood serum analysis and to assess the complication rate of the technique.
Methods and materials
39 liver-transplantated patients from different causes were recruited: 29 males and 10 females,
with a mean age of 54,6 years at the time of the procedure (min.: 41,
max.: 72 years) and a mean age of 51,4 years at the time of transplantation (min.: 24,
max.: 66 years).
The anastomosis were common bile duct-common bile duct in 34/39 cases (87%),
and were common bile duct-jejunal in the remaining 5/39 subjects (13%).
Our hospital’s institutional review board approval was used to conduct a retrospective review of...
Among the 39 patients analyzed,
27 were subjected only to balloon dilatation of the bile ducts; among them,
20 were found in the group of primary patency (Fig.
biliary patency was maintained in the long term only with the first round of dilatations.
Compared to the entire cohort,
the proportion of patients found in the “primary patency” group was 51% (Table 1).
In our study,
the number of patients belonging to the “secondary patency” group stood at 6 (of 27) (Fig.
Interventional radiology has,
in liver transplanted patients suffering from anastomotic stenosis,
the objective of restoring and ensuring biliary patency,
avoiding an early surgical re-intervention .
The effectiveness of endoscopic techniques,
as an alternative to surgery,
has been confirmed by international studies,
which demonstrated success rates ranging between 63% and 80% after bilioplasty,
with or without stent placement .However,
in some cases endoscopic approach is not preferred.
In these cases,
the method of choice becomes percutaneous.
in some centers,
such as ours,
there is greater...
