Most of the inguinal hernias in adolescents (over 8 years old) have defects and weakness of the transversal abdominal fascia, and the recurrence rate is relatively high after simple high hernia sac ligation. Therefore, it is necessary to repair the internal ring and transversal abdominal fascia during the operation, but the adolescents need to grow and develop, and if traditional non-absorbable patches are used to repair them, they will affect the future development because of the contracture of the scars, and even cause infertility due to the compression of the vas deferens. For these patients, we have introduced the advanced bioabsorbable patch for surgical repair, which has high postoperative comfort, low recurrence rate, and does not affect the growth and development and future fertility, and has achieved good results. Of course, the price of bio-patch is relatively expensive, so patients and parents need to choose rationally according to their own situation.
