Background: Kasai portoenterostomy (KPE) is the initial treatment for biliary atresia (BA). Even after initial jaundice clearance, a significant number of children presented with the reappearance of symptoms due to ongoing fibrosis involving porta and intrahepatic ducts. Mitomycin-C (MMC) is an antifibrotic agent, and the study hypothesized that local application of MMC at porta can decrease fibrosis, which can improve jaundice clearance and lead to better native liver survival (NLS). Materials and Methods: This prospective randomized control trial included children with BA, who were allocated to groups A or B. The patients in both groups underwent standard KPE; in addition, a 5 French infant feeding tube (IFT) was placed near the porta through the Roux limb in Group B children. During the postoperative period, MMC was locally instilled over the porta in Group B children through IFT. Postoperative jaundice clearance and NLS were assessed and compared. Results: A total of 27 children were enrolled in the study, 16 in Group A and 11 in Group B. Both groups were comparable preoperatively. Although the NLS was not statistically significant in Group B, the survival was quite higher, that was 91%, 81%, and 73% at 6 months, 1 year, and 2 years, respectively, compared to 63%, 50%, and 38% in Group A. Conclusion: Children in Group B clinically showed an early jaundice clearance and a better trend of serial bilirubin levels as well as longer NLS than Group A, but it was not statistically significant. The procedure was technically easy, and no complication was encountered related to surgical technique or MMC instillation.
