Final answer:
Biliary atresia is a pediatric liver disease that requires surgical intervention to restore bile flow.
Step-by-step explanation:
Biliary atresia is a pediatric liver disease characterized by the blockage or absence of the bile ducts, leading to the inability of bile to drain from the liver. This can cause liver failure and requires surgical intervention to restore bile flow. Medication to increase bile flow or dietary changes to reduce bile production are not effective in treating biliary atresia. Physical therapy is not used to improve liver function in this condition. The recommended treatment option for biliary atresia is surgery to restore bile flow.
