Intrahepatic ductal dilatation and an inability to visualize the common hepatic duct in the neonate suggests Biliary atresia.
Biliary atresia happens due to the presence of blockage in the ducts carrying bile from the liver. Due to this the bile keeps getting accumulated in the liver causing it to dilate. The first symptom of it is the occurrence of jaundice. Loss of liver tissue can also happen.
Hepatic duct is the tube-like structure that transports bile from the liver. They are divided into right and left hepatic duct which join together at the region known as the hilum.
