Can biliary atresia be misdiagnosed?
Results: Out of 147 infants, there was a misdiagnosis of BA in 10 (6.8%) infants. Alanine transaminase was significantly higher in the non-BA group, whereas other clinical and laboratory findings were comparable in both groups.
Is biliary atresia congenital?
What is Biliary Atresia? Biliary atresia is a blockage in the tubes (ducts) that carry bile from the liver to the gallbladder. This congenital condition occurs when the bile ducts inside or outside the liver do not develop normally. It is not known why the biliary system fails to develop normally.

The combination of the triangular cord sign and gallbladder abnormalities can improve diagnostic sensitivity. The absence of a gallbladder is as specific as the triangular cord sign in the diagnosis of biliary atresia.
Is the gallbladder detected on sonography in infants with biliary atresia?
The gallbladder was detectable on sonography in 13 infants with biliary atresia and 26 infants with neonatal hepatitis or other causes of infantile cholestasis. Gallbladder contraction was not confirmed in 11 of 13 infants with biliary atresia and seven of 26 infants with neonatal hepatitis or other causes of infantile cholestasis.
Is the “triangular cord” sign important in the diagnosis of biliary atresia?
A retrospective review was performed to evaluate the importance of the “triangular cord” sign in comparison with gallbladder length and contraction for the diagnosis of biliary atresia in pediatric patients. MATERIALS AND METHODS. Fifty-five fasting infants with cholestatic jaundice were examined on sonography.
What is basal biliary atresia (BA)?
Biliary atresia (BA) is a congenital biliary disorder, which is characterized by an absence or severe deficiency of the extrahepatic biliary tree.
