Open surgery for pediatric hernia has been gradually replaced by laparoscopic surgery because of disadvantages such as relatively obvious scarring, heavy injury and difficulty in probing the contralateral side for occult hernia, and is generally used only in cases of partial incarcerated hernia or restricted medical conditions. Laparoscopy can not only clearly display and clearly distinguish the inguinal hernia internal ring opening, spermatic vessels and vas deferens, but also avoid damaging the spermatic cord and vas deferens during surgery, and at the same time the location of ligation is higher than that of open surgery, which makes recurrence less likely in children after surgery, and more importantly, laparoscopy can also detect potential contralateral occult hernia, and since laparoscopic surgery for pediatric hernia is commonly performed nationwide, the detection of occult hernia (without any symptoms of hernia) is up to about 50%. If the inguinal canal is not closed, direct contralateral surgery can be performed, avoiding reoperation and anesthesia in the child. Laparoscopic treatment of pediatric inguinal hernia is a well-established technique.
