As an illustration, in 2015 the Swiss center introduced structured guidelines to diagnose BA-associated cholangitis. Upon retrospective analysis of SBAR data (2010–2022) we noted significant differences in disease management before and after implementation: The number of multiple diagnosed cholangitis episodes was reduced and we observed a reduced transplantation rate. Building on this, the Biliary Atresia and Related Diseases consensus has developed key diagnostic and management guidelines with objective criteria that have yet to undergo prospective validation. Indeed, prospective multicenter assessment is clearly needed to enhance acceptance and improve outcomes. Further, rigorous evaluation of prophylactic and therapeutic interventions, including antibiotics and immunomodulatory treatments, seems essential, with randomized trials required to establish their effectiveness and explore microbiota modulation in cholangitis management.</div><div>The BA-community should strive to establish and adopt a widely accepted protocol for the diagnosis, management and prevention of BA-associated cholangitis.

The Kasai portoenterostomy, introduced in 1950, remains the primary palliative procedure to restore bile drainage and delay the need for liver transplantation, which is required in cases of biliary flow failure. Biliary atresia continues to be the leading cause of pediatric liver transplants, accounting for up to 75 % of procedures in children under two years. While the Kasai technique has undergone numerous modifications; surgeons at Juntendo University Hospital, Japan, have modernized the procedure while preserving Dr. Kasai's original portoenterostomy principles. Since 2009, the hospital has been a pioneer in laparoscopic Kasai portoenterostomy; this article presents a detailed description of the state-of-the-art approaches and postoperative management, along with analysis of the latest outcomes.
