Sonographic evaluation of the triangular cord sign in the diagnosis of Biliary Atresia, confirmed with needle liver biopsy.
Pak Paed J Jan ;31(1):30-3.

Neonatal cholestasis continues to present a diagnostic challenge for pediatric surgeons. Various diagnostic protocols are available, often involving invasive procedures which are generally not available in the district general hospitals. The objective of this study is to evaluate the role of Triangular Cord sign (TC sign) on ultrasound for the prompt and easy diagnosis of biliary atresia in infants. A prospective study was planned. Patients with positive TC sign underwent needle liver biopsy for confirmation. Infants with neonatal cholestasis were referred from the gastroenterology department. Abdominal ultrasound was performed with 3-6MHz convex and 6-10MHz linear transducers on Core Vision, Toshiba by a single paediatric radiologist and results were correlated with needle biopsy of the liver interpreted by the histopathologist. Thirty nine Infants with cholestatic jaundice underwent ultrasound and biopsy. Twenty patients were diagnosed on ultrasound as biliary atresia on the basis of positive triangular cord sign and 18 of them were confirmed on biopsy.
