The development of modern medical technology, especially the adoption of minimally invasive laparoscopic techniques, has benefited a large number of children. Many diseases that used to require long surgical incisions can now be minimally invasive to the extent that the wounds are very small or almost invisible. For example, in this case of a girl who came to the hospital with a huge abdominal mass, the CT examination indicated multiple huge cystic lesions in the abdominal cavity, and in the past, traditional surgery required 5-10 cm or even larger incisions to complete the surgery, and such a large wound would have a great impact on the child’s future psychology. We used a simple transumbilical laparoscopic technique to remove the lesion, and how big was her entire wound in the end? It was almost invisible to the naked eye.
