jaundice, were studied between January 2005 to April 2007 in Tabriz Children`s
Hospital. All of these infants were evaluated with ultrasonography and
isotopscan and finally biopsy was done in all of them under guide of sonography.
In their sonographic evaluation, absence or presence of gall bladder,
its size and also its evacuation after feeding was checked and beside
this triangular cord sign was controlled. The PPV and specificity of triangular
cord sign in diagnosis of extrahepatic biliary atresia (EHBA) was 100%
but its NPV was only 78.5%. The overall accuracy, PPV, NPV, specificity
and sensitivity of ultrasonographic findings in diagnosis of EHBA was
about 94, 92, 94, 97 and 86%. Ultrasonography is a reliable screening
method in early diagnosis of EHBA and triangular cord sign increases its
accuracy especially its specificity.]]>Bates, M.D., J.C. Bucuvalas, M.H. Alonso and F.C. Ryckman,199818281293Cauduro, S.M.,200379107114Choi, S.O., W.H. Park and H.J. Lee,199881216Choi, S.O., W.H.
