It is completely unnecessary to perform laparoscopic surgery for pediatric inguinal hernia because a transverse or straight incision of 1-1.5 cm in size is routinely made in the lower abdomen to perform a high ligation of the hernia sac and the wound is closed with 1-2 stitches after surgery. First of all, the laparoscopic hernia sac high ligation incision is much smaller, only 0.4 cm; the operation time is short, only 5-8 minutes, and also allows for contralateral exploration for the presence of bilateral hernias. There is basically no bleeding, little pain and quick recovery after surgery; no sutures are needed and there are no scars after surgery. Secondly, laparoscopic surgery is performed in the abdominal cavity without going through the inguinal canal, and its anatomical structure is not destroyed, avoiding the possibility of damaging the spermatic cord and spermatic vessels in conventional surgery, and there are no intraoperative or postoperative complications as long as the operation is performed properly. Thirdly, the incidence of bilateral inguinal hernia in pediatric patients is 10-15%. 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 laparoscopic surgery has very obvious advantages and can be performed bilaterally with only one small incision.
