Once a very controversial field in the early 1980s, laparoscopic surgery is now widely accepted in all subspecialties of surgery and has become an important part of pediatric surgery. Laparoscopic techniques have made the management of many diseases in pediatric patients minimally invasive, and their advantages and broader applications have become apparent. Since laparoscopy allows the surgeon to observe the entire abdominal cavity through a 5 or 10 mm incision in the umbilical fossa, with little impact on the child, it eliminates the need for “open surgery” in the diagnosis of some diseases. At the same time, due to the improvement of laparoscopic operation technology and surgical instruments, many pediatric abdominal surgeries can now be done laparoscopically, making a giant leap forward in the diagnosis and treatment of pediatric abdominal diseases. Advantages of pediatric laparoscopic surgery: small incision, little damage to the abdominal wall, inconspicuous and beautiful postoperative scar; small surgical trauma, little postoperative pain and fast recovery; wide and clear surgical field of view due to the magnifying effect of the laparoscopic lens, allowing the surgeon to perform precise and accurate separation, hemostasis, ligation and suturing operations as if operating under a magnifying glass; comprehensive observation of the abdominal cavity, and simultaneous treatment of upper and lower abdominal It allows the surgeon to perform precise and accurate separation, hemostasis, ligation and suturing operations; to observe the abdominal cavity comprehensively and to deal with both upper and lower abdominal lesions; and to reveal areas that are difficult to expose by conventional open surgery, such as the posterior bladder area and the subdiaphragmatic area. We have acquired an advanced pediatric laparoscopic system and LigaSure laparoscopic closure/divider and have performed pediatric laparoscopic surgery. Laparoscopy has shown strong advantages in some diseases such as examination and treatment of cryptorchidism where the testicles cannot be reached, appendectomy, pyloric cricothyrotomy, resection of Meckel’s diverticulum, treatment of varicocele, fundoplication, radical resection of megacolon, and high anus-free anoplasty.
