The Gessy procedure can be performed without liver replacement. Gessy’s surgery, also known as hepaticojejunostomy, is a surgical procedure used to treat congenital biliary atresia. It is mainly aimed at reconstructing the bile ducts to restore bile drainage, and expanding the scope of treatment for biliary atresia, which is a brand new surgical procedure in pediatric surgery at the moment, and therefore most of the patients will not need to have their livers replaced after Gessy’s surgery. Congenital biliary atresia is a clinical condition in which the bile ducts that carry bile from the liver to the gallbladder are occluded while the fetus is still in the womb and the pregnant woman is in the perinatal period, resulting in the inability of fetal bile to be excreted from the body, and bile accumulates for a prolonged period of time, which can lead to damage to the liver’s function. Patients who need to undergo biliary atresia Gessy surgery need to be treated with liver protection and yellowing support before the surgery, and also need to be observed after the surgery to keep the patient’s condition, keep the diet smooth after the surgery, and strengthen the patient’s nutrition so as to avoid all kinds of complications after the surgery.
