Clinical Trial Summary

The investigators plan to investigate the use of US shear wave elastography (SWE), a newly available imaging technology, in children with suspected/known BA.


Description:

The investigators plan a prospective, multi-center study to determine if liver ultrasound shear wave speed measurements acquired at clinical presentation can discriminate biliary atresia (BA) from other causes of liver disease in the setting of neonatal cholestasis. The investigators also plan to determine if liver ultrasound shear wave speed measurements acquired at clinical presentation or longitudinally during the first one-year period after Kasai can predict important long-term outcomes in BA patients.

Intervention

Device:
Ultrasound Shear Wave Elastography
The investigators have recently published a very small study in neonates/infants with suspected BA showing that US liver shear wave speed (i.e. - liver stiffness) can differentiate BA from other causes of cholestasis, potentially with a very high degree of accuracy. Additional research is needed to confirm these very preliminary results and determine if liver shear wave speed measurements either before or after (including longitudinally) Kasai can predict key outcomes.

Outcome

Type Measure Description Time frame Safety issue
Primary Discrimination of biliary atresia from other liver diseases using ultrasound liver shear wave speed (Aim 1) The primary outcome measure will be ultrasound shear wave speed of the liver. The investigators will compare the mean liver shear wave speed measurements in children with biliary atresia to other liver diseases. Sensitivity and specificity of ultrasound for diagnosing biliary atresia will be determined using multiple shear wave speed cut-off values. 2 years
Secondary Predicting long term clinical outcomes in biliary atresia patients using ultrasound liver shear wave speed (aim 2) Change in shear speed liver over time will be compared between children with biliary atresia versus other liver diseases in order to determine if differences predict important clinical outcomes. 6 years
