Abstract:The morbidity and mortality from biliary atresia cannot be overemphasized. Therefore, its early
detection especially using a non invasive means will go a long way in preventing liver cirrhosis, liver failure
and even death from this disease entity. This study was done to highlight the abdominal scan findings in infants
suspected to have biliary atresia, demonstrate the Triangular Cord sign (TC) and to assess how many of these
were confirmed at surgery. It is a prospective study of 25 consecutive jaundiced infants sent to the Radiology
department of a Teaching Hospital for abdominal ultrasound scan, on account of persistent elevated conjugated
bilirubin and thus the suspicion of biliary atresia. The Triangular cord sign, liver size and echotexture,
gallbadder longitudinal diameter, pre and postprandial were assessed. Infants that were highly suspected for
biliary atresia were operated and findings were correlated with ultrasound findings. About a third of the infants
scanned had a positive Triangular cord sign, only three of whom were found to be positive at surgery. The
Triangular cord width ranged from 0.07 - 4.7mm, with a mean of 2.62 +1.23 mm.This study confirmed that TC
measuring 3.5 - 4mm or more on ultrasound is diagnostic of biliary atresia.
