Abstract

Aims: Biliary atresia (BA) is a congestive biliary disease that develops in the neonatal period or early infancy. It may present with portal hypertension and varices needing treatment (VNT) even after successful Kasai portoenterostomy. This study aimed to stratify the risk of VNT in children and adolescents with BA.

Methods: In this prospective cross-sectional study, we measured liver stiffness (LS) and spleen stiffness (SS) by two-dimensional shear wave elastography and checked for VNT endoscopically in 53 patients with BA who attended for follow-up between July 2018 and September 2022. Varices needing treatment were defined as large esophageal varices, esophageal varices of any size with red color signs, and/or gastric varices along the cardia.

Results: Twenty-five patients (aged 0-18 years) had VNT. Eighteen patients met the Baveno VI criteria (LS <20 kPa; platelet count >150 000/L) and were deemed to be at low risk of VNT (spared endoscopies) while three had missed VNT (16.7%). Applying the Baveno VII criteria, which combines the SS cut-off value of 40 kPa with the Baveno VI criteria, resulted in five missed VNTs among 22 spared endoscopies (22.7%). A modification of the Baveno VII criteria using the aspartate aminotransferase-to-platelet ratio index (APRI) instead of the platelet count with cut-off values of 25 kPa, 30 kPa, and 1.04 for LS, SS, and APRI, respectively, missed only one VNT (5.0%) among 20 spared endoscopies.

Conclusions: A novel diagnostic criterion that combines LS, SS, and APRI reduced the risk of missing VNT to 5% in children and adolescents with BA.
