Question
The newborn is 44 days old and had jaundice at birth. After blue light treatment, there is still slight jaundice, the color of the stool is normal, and white stool has never been excreted. How can bile duct obstruction be diagnosed through an ultrasound report?
Answer
Congenital bile duct obstruction is one of the common malformations in the neonatal liver and bile system, which usually manifests symptoms within 3 to 4 weeks after birth. It is difficult to detect during pregnancy, and diagnosis requires an ultrasound examination after birth. Ultrasound examination can show abnormalities in the bile duct system, including the size and shape of the gallbladder and intrahepatic bile ducts, as well as the presence of bile stasis. The doctor will make a comprehensive judgment based on the examination results and clinical symptoms to determine whether it is bile duct obstruction. Once diagnosed, treatment measures should be taken as soon as possible.
