1. Hernia (inguinal hernia) in children is a disease caused by congenital tissue dysplasia, and some children can be cured through conservative treatment. Most children with inguinal hernia have healthy tissues around the internal ring, and the levator muscle is more developed, and because the tissue spacing is smaller in children, the tissue-to-tissue repair is less tense and more solid at the same time. 3. If synthetic materials are used for repair, because of the shrinkage of the materials themselves and the growth and development of the child, from a long-term perspective, synthetic materials cannot provide long-term protection for the affected area of the child, but rather affect its local growth and development. 4. Some studies have found that synthetic materials (mainly polypropylene materials) in contact with the spermatic cord or vas deferens can have an impact on their ability to transport sperm, leading to infertility. 5. If the affected child has a very large congenital defect, a biological patch may be considered. Because biological patches are made of decellularized matrix, they only provide support for a certain period of time and will be metabolized in the human body and will not affect the growth and development of the affected child.
