Laparoscopic versus open Kasai procedure for biliary atresia: long-term results of a randomized clinical trial.

ABSTRACT

PURPOSE: The role of the laparoscopic approach for the Kasai procedure in the management of biliary atresia is still controversial. The aim of this study is to compare the long-term results of the laparoscopic Kasai procedure (LKP) to the open Kasai procedure (OKP). METHODS: A randomized clinical trial was carried out from October 2009 to March 2017. Patients diagnosed with biliary atresia type III were randomized into 2 groups one group underwent LKP and the other group-OKP. All the surgical procedures were performed by the same surgeon with the same technical principles. The long-term outcomes were compared between the two groups. RESULTS: 61 patients underwent LKP and 61 patients-OKP, with a median age at the surgery of 79.7 days. The two groups had no significant differences regarding the patients' baseline characteristics. At follow-up up to 142 months, the jaundice-free rate at the 6th postoperative month for LKP and OKP was 52.5% and 60.7%, respectively (p = 0.23). The 10-year cumulative survival after LKP tended to be inferior to OKP, respectively 44.3% vs. 58.9% (p = 0.09). CONCLUSIONS: In this study, the long-term results of LKP tended to be inferior compared to OKP although the differences were not significant.
