Biliary atresia can be cured by surgery and surgical treatment is the only effective method. The prognosis is poor if surgery is performed too late. Biliary atresia is the most common cause of persistent jaundice in newborns. It is characterized by persistently worsening jaundice, accompanied by clay-colored stools and strong tea-like urine. Surgery is the only effective treatment and should be performed within the first 2 months of life, before irreversible liver damage occurs. If surgery is performed too late and the child has developed biliary cirrhosis, the prognosis is very poor. If the child has biliary atresia, the patient should seek medical advice and undergo surgery under the supervision of a doctor, depending on the specific conditions of the child. After the operation, the patient should strictly follow the doctor’s instructions to take medication, review, and pay attention to strengthen the nutrition and so on.
