Gessy’s surgery is mainly used for the treatment of biliary atresia in clinic, however, not all biliary atresia can be treated with Gessy’s surgery, only a small portion of children can be completely cured after Gessy’s surgery, and the survival time may be up to 20 years, or even more than 30 years. In many children with biliary atresia, even after Gesell’s surgery, the disease will progress and eventually lead to cirrhosis, portal hypertension, or even liver failure, and these children will eventually need a liver transplant to save their lives. The success of the Gessy procedure depends not only on the type of biliary atresia, but also on the condition of the biliary atresia, and the procedure should be performed as close as possible to three months after birth. If cirrhosis is already present, the Gessy procedure will not solve the problem, and then a liver transplant will be necessary to save the life of the newborn. Therefore, the exact prognosis of the Geshe procedure is a combination of many factors. Newborns after Gessy’s operation should have their liver function and blood counts checked regularly for infections and liver function abnormalities, and many newborns may need long-term oral ursodeoxycholic acid and liver-protecting medications.
