Biliary atresia is a progressive liver disease in infants where liver transplantation is often the only long-term option once cirrhosis develops. However, organ shortages, high costs, risks of graft rejection, and the need for lifelong immunosuppression make transplantation difficult for many families. This double-blind randomized clinical trial evaluates whether injecting umbilical cord-mesenchymal stem cells directly into the liver during Kasai portoenterostomy is safe and effective as an additional treatment. Umbilical cord stem cells have strong anti-inflammatory and anti-fibrotic properties, and they carry a low risk of immune rejection. Patients undergoing the Kasai procedure are randomly assigned to receive either direct intrahepatic stem cell injections or a placebo. Participants are followed for 180 days post-surgery to monitor safety, liver function, and changes in liver stiffness.
77 studies on the registry are indexed under Biliary Atresia; 25 are open to participants now.
This study's planned enrollment of 40 is below the median of 45 across 43 interventional studies indexed under Biliary Atresia.

Drop-out Criteria:
- Subjects will be dropped from the study if they develop postoperative anastomotic leakage
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Infants aged 30-90 days with intraoperative cholangiography-confirmed biliary atresia undergoing Kasai portoenterostomy receive intraoperative intraparenchymal injections of umbilical cord-derived mesenchymal stem cells (UC-MSCs) across hepatic segments 3, 4, 5, and 6, at a target dose of 10\^5 cells/kg (prepared in a 1 mL syringe at a concentration of 10\^5 cells/0.1 mL in 0.9% NaCl)
Biological: Umbilical Cord-Mesenchymal Stem Cells (UC-MSC) · Procedure: Kasai Portoenterostomy
Infants aged 30-90 days with intraoperative cholangiography-confirmed biliary atresia undergoing Kasai portoenterostomy receive intraoperative intraparenchymal injections of a placebo solution (prepared in a 1 mL syringe containing 0.9% normal saline) across hepatic segments 3, 4, 5, and 6.
Procedure: Kasai Portoenterostomy
Intraoperative intraparenchymal injection of umbilical cord-derived mesenchymal stem cells (UC-MSCs) at a dose of 10\^5cells/kg, administered via a 1 mL syringe containing UC-MSCs at a concentration of 10\^5 cells/0.1mL in 0.9% NaCl, distributed across hepatic segments 3, 4, 5, and 6 in both liver lobes

Pediatric End-Stage Liver Disease-Creatinine (PELD-Cr) Score
The Pediatric End-Stage Liver Disease-Creatinine (PELD-Cr) score is used to assess liver disease severity and estimate mortality risk in pediatric patients with end-stage liver disease. In accordance with Organ Procurement and Transplantation Network (OPTN) policy, the minimum score for this scale is capped at 6 (any calculated laboratory score below 6 is reported as 6), and there is no upper limit or maximum score. Higher PELD-Cr scores indicate greater liver disease severity and a worse clinical prognosis.

Liver Fibrosis Stages
Evaluated by measuring liver stiffness via Acoustic Radiation Force Impulse (ARFI) ultrasound, mapped to the METAVIR Fibrosis Staging Scale.
