Strictly speaking, minimally invasive laparoscopic surgery can be attempted in all children, giving the child a chance to be minimally invasive. If during the minimally invasive surgery it is found that the abdominal operation is difficult to complete the surgery, it can be promptly transferred to open surgery. The main factor that determines whether minimally invasive laparoscopic surgery can be performed successfully is the condition of the child itself. If the child has heavy abdominal adhesions and inflammation in the abdominal cavity, then it will be converted to open surgery under the premise of ensuring life safety. On the other hand, whether the minimally invasive surgery can be performed successfully or not is related to the parents. If the child comes to surgery when the disease is discovered, the child’s condition is relatively mild and the chance of minimally invasive surgery is greater. For children with acute perforation of the common bile duct cyst or perforation with drainage tube placed, laparoscopic minimally invasive exploration is usually possible first, and if conditions allow, then minimally invasive surgery can be performed, and if the abdominal adhesions are heavy, then open surgery will be converted. For children who have undergone surgery for choledochal cysts in outside hospitals, postoperatively due to anastomotic stenosis or atresia, open surgery is usually used. The choice of all surgical methods, i.e. whether minimally invasive treatment can be performed, is mainly determined by the condition of the child, so the earlier the treatment, especially for children with insignificant symptoms, minimally invasive surgery is the best choice and the best time for minimally invasive surgery.
