Inguinal hernias have a high incidence in children. It often appears congenitally or can occur later. In those who are older than 2 years and do not heal on their own, surgery is the only reliable treatment. The traditional surgery is an open procedure in which the hernia sac is separated from the spermatic cord and ligated at a high level, thus achieving treatment, and has been a well-established procedure for many years. However, its biggest drawback is bleeding and spermatic cord harassment, which may cause local adhesions and affect the normal development and function of the spermatic cord. In recent years, with the development of laparoscopic technology, the technique of pediatric lumpectomy hernia surgery has become more and more perfect, and the outstanding technical advantages and good results are increasingly accepted by the majority of colleagues and parents of children. Method: A 5-mm incision is made in the umbilicus to insert the lumpectomy, the hernias are clearly explored, a small 2-mm incision is poked at the hernia ring with a wire puncture, and the hernia ring is ligated circumferentially, and the surgery is completed. Advantages: small incision without sutures and stitch removal; magnification of the lumpectomy allows clearer visualization of the spermatic cord, vas deferens, and subabdominal vessels, thus minimizing damage; no spermatic cord harassment; almost no bleeding; ligation at the hernia ring makes recurrence less likely; faster recovery and small hidden scars from the incision. It is especially suitable for bilateral hernias and recurrent hernias.
