Pediatric inguinal hernia, one of the common diseases in children, is caused by the failure of the peritoneal sphincter to close during fetal descent with the testis. The hernia sac is closely related to the spermatic cord, especially at the distal end of the internal ring opening. A small number of children may heal spontaneously with conservative management before the age of one and a half years, but the majority of children require surgical treatment. The current academic opinion on the choice of procedure for hernia in children under 14 years of age is unanimous – high ligation of the hernia sac. Although the traditional high ligation of the hernia sac is effective, the surgical incision is relatively long, the postoperative pain is more pronounced, and most critically and most worryingly, the spermatic cord is damaged when the hernia sac is removed! Because the relationship between the distal end of the hernia sac and the spermatic cord is very close and the spermatic cord itself is very small in children, it is easy to injure the spermatic cord during open surgery, which can cause poor blood supply to the testes or affect fertility in severe cases. Laparoscopic surgery is performed directly through the abdominal cavity by suturing the internal ring, without destroying the anatomical structure of the inguinal region, without destroying the levator muscle, without freeing the spermatic cord, thus avoiding the disturbance of the spermatic cord due to vascular nerve injury, and the operation is simple. The laparoscopic procedure is unique for bilateral hernias and cryptic hernias because it avoids the pain of secondary surgery and saves the cost of surgery. The laparoscopic procedure has a low infection rate after surgery, and the incision scar is small and beautiful, which is easily accepted by parents of children.
