The incidence of inguinal hernias in various age groups of children ranges from 0.8 to 4.4%. Pediatric indirect inguinal hernia is congenital, originating in the patent processus vaginalis. The inguinal hernia repair is one of the most common pediatric operations. The traditional high hernia sac ligation is the primary treatment for younger patients from 1 to 13 years of age and can correct the condition. The authors performed the high ligation of the hernia sac by the laparoscopic approach for the patients under 13 years old and achieved good therapeutic results in the last 10 years. However, through our clinical study, the authors found that the simple high ligation of hernia sac is inadequate for patients from 13 to 18 years of age, who had a longer medical history, larger diameter of the internal inguinal ring, and more serious defects of the transverse fascia. Pediatric inguinal hernias are prone to postoperative recurrence if the patients were only treated with the high ligation of hernia sac. To repair the transverse fascia and strengthen the posterior wall of the inguinal canal, Lichtenstein hernioplasty with a biological patch was performed for the patients from 13 to 18 years in the authors' department. The aims of this chapter are to narrate the individualized treatment of inguinal hernia in children and try to provide relatively reasonable operative methods.
