ABSTRACT
Objective To evaluate the differential diagnostic value and superior of biliary atresia(BA)in the infants with cholestatic hepatopathy by high-frequency ultrasonography (HUS).Methods After 4 hours fasting,124 infants with cholestatic hepatopathy were scanned with high-frequency US.The data of hepatic size and parenchyma,gallbladder,triangular cord (TC) sign,bile duct,right hepatic artery (RHA)and portal vein (PV) were observed and measured.Meanwhile,the other data were collected,which included the clinical diagnosis,blood biochemical tests,the MRCP and dynamic duodenal liquid color check finding,the pathological results after liver puncture biopsy and so on.Results In 124 infants with cholestatic hepatopathy,BA was found in 61 infants and ruled out in 63.TC thickness,RHA diameter,and gallbladder length and width exhibited significant differences between the group with BA and the group non-BA(all P <0.001).The correctness for the diagnosis of BA was 90.3% by the combination of TC sign and abnormal gallbladder morphology,and 83.1 % by stool color,81.5 % by γ-GT,47.5 % by MRCP,83.3 % by dynamic duodenal liquid color check,95.2% by the pathology after liver puncture biopsy,respectively.Conclusions HUS is superior to other diagnostic methods in BA with higher accuracy rate,noninvasion,simplicity and economy.
