Biliary atresia is mainly seen in newborns and is a congenital disease. The survival time of children with the disease is mostly related to their own constitution, severity of the disease and treatment, and cannot be generalized. The clinical symptoms of biliary atresia are mainly jaundice, with the development of the disease, jaundice gradually aggravated, the color of urine is thick tea-like, stool color gradually becomes lighter, white clay-like. If abnormalities are found, the baby needs to be taken to the pediatric department of the hospital in a timely manner. Once biliary atresia is diagnosed, surgery should be performed as early as possible and as soon as possible to avoid delaying the surgery, increasing the difficulty of rescue and treatment, and even leading to death. Currently, there are two types of treatment, Gussy surgery and liver transplantation, especially liver transplantation is the best treatment. The Gracie procedure can provide relief for a short period of time, but as the disease progresses, liver transplantation may eventually be required. Liver transplantation, on the other hand, can provide a longer survival period for children with biliary atresia, and even long-term survival with proper postoperative care. However, liver transplantation is relatively expensive and the source of liver is extremely tight. In the absence of liver source in the early stage, simple rerouting surgery can be chosen to lift biliary atresia to ensure the current quality of life and to win time for liver transplantation.
