Pediatric hernia, or pediatric inguinal hernia, is one of the most common surgical disorders in children, with a general incidence of 1-4%, the cause of which is related to both weakened abdominal wall and high intra-abdominal pressure. Although a small percentage of children have the potential to heal spontaneously with conservative management before the age of half a year, the majority of children have recurrent disease. To prevent life-threatening emergencies such as incarcerated hernia, the only way to cure the disease completely is to use surgical methods early. The traditional surgical procedure is a high ligation of the hernia sac. Although these procedures have definite results, the surgical incision is relatively long and the postoperative pain is more pronounced in the sick child. Because the spermatic cord is immature and very small in children, and because the normal anatomy of the inguinal region is disrupted during surgery, the spermatic cord is easily damaged during these open surgeries. In laparoscopic pediatric hernia surgery, two small incisions are made in the abdominal wall (commonly known as “eyelets”) with a diameter of 3 to 5 mm, and a trocar is placed into the abdominal cavity to establish a channel between the abdominal cavity and the outside world. Using these channels, special laparoscopic surgical instruments, and with the help of a camera device, the surgeon can clearly see the image of the abdominal cavity on the surveillance screen and complete the surgical operation. Laparoscopic surgery allows direct suturing of the internal ring of the hernia without disrupting the anatomy of the inguinal region, thus avoiding damage to blood vessels and nerves. Laparoscopic surgery also allows for the exploration of the contralateral internal ring orifice. If an occult hernia is found on the contralateral side, it can be ligated directly. This not only avoids the pain of secondary surgery but also saves the cost of surgery, so laparoscopy is uniquely superior for the treatment of bilateral hernia and cryptic hernia. Currently, most of the pediatric surgery departments in large hospitals or pediatric specialty hospitals in China are performing and recommending laparoscopic high ligation of hernia sacs for children with hernia. Our pediatric surgery department performs a large number of laparoscopic high ligation of hernia sacs. Among them, 3 cases of contralateral hiatal hernia were found, avoiding a second operation in the child later. All children recovered well with parental satisfaction and had good social benefits. The advantages of this procedure are: ①small incision, no skin suture, no obvious scar; ②slight postoperative wound pain, reducing the phenomenon of increased abdominal pressure due to postoperative crying of the child, and reducing the difficulty of postoperative care; ③quick recovery, short hospitalization time, and discharge in 1 to 2 days after surgery.
