Performing Kasai portoenterostomy beyond 60 days of life is not necessarily associated with a worse outcome

The introduction of Kasai portoenterostomy has dramatically improved the management and survival of children with biliary atresia. The success rate of this operation worldwide varies with different centers. In this respect, many authors have studied the correlation of a successful outcome with various factors, such as the experience and workload of the surgical center, the use of postoperative steroids, the underlying biliary anatomy, as well as the age of patients at the time of the operation. Indeed, the age of 60 days has been used by clinicians as a critical time beyond which the rate of success of the Kasai operation markedly reduces. Despite this worldwide adoption, clear evidence supporting this critical operative time is still lacking. We undertook a review of our experience in the management of children with biliary atresia and focused specifically on the issue of the timing of operation. We showed that performing the Kasai operation beyond the age of 60 days was not associated with a worse outcome and that a high percentage of patients could still achieve good bile flow with normal bilirubin postoperatively. Thus, we believe that until the age of 100 days, the age of the patients does not play a significant role in determining the success of the Kasai operation.link_to_subscribed_fulltex
