Objectives To evaluate feasibility, safety and mid-time outcome of pediatric liver transplant patients treated with a biodegradable biliary stent for anastomotic biliary strictures.
Methods Retrospective study of pediatric liver transplant patients treated using a biodegradable stent for anastomotic biliary strictures from January 2014 to December 2016. The stricture was diagnosed using US, MR and liver tests and confirmed using a cholangiography. During the cholangiography, a dilation with an angioplasty balloon was performed and an internal-external drainage was inserted. Two weeks after the first procedure, a control cholangiography was done. In patients with biliary stricture persistence, a tailor-made biodegradable biliary stent was placed. Patients were followed clinically, biochemically and using US.
Results A total of 11 stents were placed in 10 pediatric liver transplant patients with a median age of 5.8 years [8months – 11 years]. The stent placement was done through percutaneous transhepatic access, without incidences, a median of 8.5 weeks after the first dilation. The median follow-up was 7.2 months [2 weeks – 25.7 months]. No complications related to the stent placement were observed during the follow up. A 50% decrease in the values of ALT, GGT and bilirubin was observed a median of 15 days [2 – 46] after stent placement. The stent was visible by US at 1, 3 and 6 months after the placement in 100%, 77% and 62% of the patients, respectively. Neither migration nor restenosis were observed during the follow up.
Conclusion Percutaneous biodegradable biliary stents was a feasible, safe and effective treatment in pediatric liver transplant patients with anastomotic biliary stenosis.
