Pediatric inguinal hernia is routinely in the lower abdomen to do a 1cm size transverse incision or straight incision hernia sac high ligation, postoperative wound suture 1-2 stitches, there is no need for laparoscopic surgery, in fact, this view is wrong. First of all, laparoscopic hernia sac high ligation incision is much smaller, only 0.3-0.5cm; the operation time is short, only about 10 minutes, and can also be carried out contralateral exploration, whether there is bilateral hernia. The surgery is essentially bloodless, with little pain and quick recovery; no stitches are needed and there is no scarring after the surgery. Secondly laparoscopic surgery is performed in the abdominal cavity without passing through the inguinal canal, its anatomical structure is not destroyed, avoiding the possibility of damage to the spermatic cord and spermatic cord blood vessels in conventional surgery, as long as the operation is done properly, there are no complications during and after the operation. Thirdly the incidence of pediatric inguinal hernia is high bilaterally, conventional surgery is to cut a large transverse incision in the middle of the lower abdomen or two small incisions on both sides for surgery, while the advantages of laparoscopic surgery are very obvious, only a small incision can be used to complete the bilateral surgery.
