Question
My baby is four months old and has developed a yellowish complexion, refuses to breastfeed, and cries. We went to a local community hospital for a check-up, and the doctor suspects bile duct obstruction and recommends a B-ultrasound examination. I would like to ask if B-ultrasound can confirm bile duct obstruction?
Answer
The definitive diagnosis of bile duct obstruction requires a liver biopsy and bile duct imaging. If the liver and bile duct system are normal, the likelihood of bile duct obstruction is relatively low. Ultrasound of the liver and bile duct system can be used for preliminary diagnosis. If bile duct obstruction is suspected, additional tests such as bilirubin measurement and bile duct imaging should be conducted. If the child is diagnosed with bile duct obstruction, it is advisable to seek treatment at a hospital with at least a third-level classification to avoid complications such as bile stasis affecting liver function. It is recommended to undergo further examination at a hospital.
