Biliary complications in pediatric liver transplant recipients with over 20 years of follow-up

This single-center descriptive study analyzed 40 pediatric liver transplant recipients from a program established in 1995, with follow-up exceeding 20 years. The study examined the management of late biliary complications, which included standard interventional options like percutaneous bilioplasties and surgical revisions of anastomoses, as well as a conservative approach with close monitoring. No comparator group was reported.

Among the 40 patients, 13 developed biliary complications. Of these, 5 complications occurred within the first post-transplant year, while 8 were late complications. The study did not report effect sizes, p-values, or confidence intervals for these outcomes. Safety and tolerability data for the management approaches were not reported.

Key limitations include the single-center, observational design with a small sample size. The study did not include statistical comparisons or a control group. The authors note this is a descriptive analysis that cannot infer prevalence beyond this specific cohort or determine the superiority of conservative versus interventional approaches. The findings are based on small subgroup analysis.

For practice, the study identifies a subgroup of pediatric liver transplant recipients that may benefit from a more conservative approach to biliary complication management, provided they are closely monitored through a rigorous follow-up protocol. However, clinicians should interpret these findings cautiously given the descriptive nature of the evidence and lack of comparative effectiveness data.
