Brief summary
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.
Interventions
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
Standard surgical resection of extrahepatic biliary remnants with a Roux-en-Y portoenterostomy to restore bile drainage in biliary atresia patients

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Total Bilirubin Level | Baseline, Post-Operative Day 7, Post-Operative Day 30, Post-Operative Day 90, Post-Operative Day 180 | Measurement of total bilirubin level |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| ALT(Alanine Transaminase) Levels | Baseline, Post-Operative Day 7, Post-Operative Day 30, Post-Operative Day 90, Post-Operative Day 180 | Hepatocellular injury marker |
| Gamma-glutamyl Transferase (GGT) | Baseline, Post-Operative Day 7, Post-Operative Day 30, Post-Operative Day 90, Post-Operative Day 180 | Cholestasis marker |
| Serum Albumin Level | Baseline, Post-Operative Day 7, Post-Operative Day 30, Post-Operative Day 90, Post-Operative Day 180 | Marker of liver synthesis function and nutrition status |
| Prothrombin Time (PT), INR | Baseline, Post-Operative Day 7, Post-Operative Day 30, Post-Operative Day 90, Post-Operative Day 180 | Coagulation parameter to assess liver synthesis function |
| Complete Blood Count | Baseline, Post-Operative Day 7, Post-Operative Day 30, Post-Operative Day 90, Post-Operative Day 180 | Hematology panel including hemoglobin, leukocyte count, platelet count, absolute neutrophil count (ANC), and hematocrit. |
| Direct Bilirubin Level | Baseline, Post-Operative Day 7, Post-Operative Day 30, Post-Operative Day 90, Post-Operative Day 180 | Measurement of direct bilirubin level |
| Indirect Bilirubin Level | Baseline, Post-Operative Day 7, Post-Operative Day 30, Post-Operative Day 90, Post-Operative Day 180 | Measurement of indirect bilirubin levels |
| Pediatric End-Stage Liver Disease-Creatinine (PELD-Cr) Score | Baseline, Post-Operative Day 7, Post-Operative Day 30, Post-Operative Day 90, Post-Operative Day 180 | 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. |
| Jaundice Clearance | Baseline, Post-Operative Day 7, Post-Operative Day 30, Post-Operative Day 90, Post-Operative Day 180 | Postoperative jaundice resolution, assessed through clinical evaluation and total/direct serum bilirubin levels. |
| Liver Fibrosis Stages | Baseline, Post-Operative Day 7, Post-Operative Day 30, Post-Operative Day 90, Post-Operative Day 180 | Evaluated by measuring liver stiffness via Acoustic Radiation Force Impulse (ARFI) ultrasound, mapped to the METAVIR Fibrosis Staging Scale. The scale ranges from a minimum score of 0 (F0: no fibrosis) to a maximum score of 4 (F4: cirrhosis). Higher scores indicate greater liver fibrosis severity and a worse clinical outcome. |
| Regulatory T-cell (Treg) levels | Post-Operative Day 7 | Regulatory T-cell (Treg) levels as an immunological parameter, measured postoperatively using flow cytometry and reported in standard laboratory units. |
| CD11c Levels | Post-Operative Day 7 | CD11c-positive immune cell marker levels, measured postoperatively via flow cytometry and reported in standard laboratory units. |
| Postoperative Cholangitis Incidence | Baseline, Post-Operative Day 7, Post-Operative Day 30, Post-Operative Day 90, Post-Operative Day 180 | Incidence of postoperative cholangitis, diagnosed based on clinical symptoms, physical examination, and supporting diagnostic tests as evaluated by the attending physician. |
| Length of Stay | From the date of surgery until initial hospital discharge or death during the same period of care with the surgery, whichever occurs first (assessed up to 12 months). | Calculated as the number of consecutive days from the date of surgery to the date of initial hospital discharge or in-hospital death during the index hospitalization. Re-admissions following initial discharge are excluded. |
| AST (Aspartate Transaminase) Levels | Baseline, Post-Operative Day 7, Post-Operative Day 30, Post-Operative Day 90, Post-Operative Day 180 | Hepatocellular injury marker |
| All-Cause Mortality | From the date of study enrollment until death, assessed up to 12 months. | Evaluated as the incidence of death from any cause occurring during the study period. Cause of death are verified through electronic medical record documentation, official death certificates, or direct patient/family follow-up contact. |
