Traditional surgery often requires a large incision to fully reveal the surgical purpose, which inevitably causes artificial tissue destruction, bringing varying degrees of pain, bleeding and post-operative incision scars to patients, and even affecting functional recovery. As a representative of minimally invasive surgery, “laparoscopic surgery” has evolved from “no access” through natural orifices to “no access” through artificial channels, which can cure diseases while It can still preserve the integrity and beauty of the appearance and restore the physiological functions of the human body, and strive to minimize the damage to the patient in the overall medical process, so as to achieve the purpose of treating the patient, treating the human body well and caring for the patient, which fully embodies the concept of “people-oriented” minimally invasive medicine, which is obviously in the interest of the patient. Laparoscopic technology is the direction of surgical development in the world today, and this technology is popular among patients and readily accepted by surgeons because of its advantages of small incision, little damage, easy and quick operation, fast recovery, little or no scar, etc. Our pediatric surgery department uses laparoscopy to treat pediatric surgical diseases – hiatal hernia (small bowel gas), syringomyelia, appendicitis, cryptorchidism, and megacolon – with good results. The use of laparoscopic technology has enabled us to have obvious advantages over traditional surgical methods: 1. Small incision, only 0.2 cm. 2. Small surgical injury. 3.Simple operation and short operation time. 4, basically no bleeding. 5.Less pain after surgery, quick recovery and shorter hospitalization time. 6.Small trauma, so there is no scar after surgery. 7.It can be explored whether there is bilateral hernia, because the incidence of bilateral inguinal hernia in children is 5-8%. Conventional surgery is performed by making a large transverse incision in the middle of the lower abdomen or two small incisions on both sides, while the advantage of laparoscopic surgery is very obvious, and the bilateral surgery can be completed with only two small incisions.
