Recently, a 13-year-old girl was diagnosed with “acute suppurative appendicitis” and admitted to the hospital as an emergency due to “abdominal pain for 1 day”. The family decided to perform surgery after communicating with the child’s family, considering that the child had already reached puberty and that the traditional laparoscopic surgery would result in two 1cm-long scars outside the umbilicus, which might affect the girl’s aesthetics and make her feel inferior among her classmates. Acute appendicitis is one of the common pediatric emergencies, and due to the characteristics of the pediatric population, acute suppurative appendicitis needs to be treated surgically as soon as it is diagnosed, otherwise the chances of perforation are high. The original open appendectomy not only has a long incision of 5-8 cm, but also leaves a large scar in the abdomen after surgery, and the postoperative recovery time is long, and the possibility of septicemia, infection and splitting of the incision is high; in the 1990s, with the introduction of laparoscopic technology into China, its advantages of small trauma and fast recovery soon emerged, and it was gradually carried out in many large hospitals across the country. With the further development of minimally invasive concept, our pediatric surgery department took the lead in successfully carrying out single-hole laparoscopic technology via umbilicus, which not only further reduced the surgical trauma without affecting the surgical effect, but also reduced the incidence of postoperative complications and shortened the postoperative hospitalization period of the child. The postoperative abdominal scarring in the child’s life and psychological impact was eliminated.
