Validated non-invasive examinations are necessary to monitor liver fibrosis in children with biliary atresia (BA) after the Kasai procedure. ⋯ 2D-SWE, TE, APRI, and FIB-4 score are accurate non-invasive markers for monitoring native liver fibrosis in patients with BA. Combined use of serologic markers and US elastography could yield more accurate diagnoses of liver fibrosis than serologic markers alone.
