Pediatric hernia mainly includes congenital inguinal hernia and umbilical hernia. Inguinal hernia is mainly caused by the failure of the sphincter to close, which is due to its inability to shrink and close in time; low birth weight infants are born with incomplete growth and development; inguinal hernia in children over one year of age does not heal spontaneously; umbilical hernia should be considered for surgery if the age is above 4 years or the diameter of the umbilical ring is 2-3 cm and above. The main clinical manifestation of pediatric hernia is the appearance of a sometimes absent and sometimes large mass in the inguinal region or umbilical orifice. As the hernia grows larger with age, it can become embedded and even cause infarction and atrophy of the testes and ovaries, so it should be treated promptly. Treatment includes two methods: (1) Conservative treatment: inguinal hernia and umbilical hernia in children within one year of age have the possibility of self-healing …… Conservative treatment is generally handled by wearing a hernia belt and reducing the crying and coughing and constipation of the child to avoid the increase of intra-abdominal pressure. (2) Surgical treatment: It is usually believed that inguinal hernia in children over one year old cannot be cured and should be treated surgically, but age is not an absolute factor and should also be combined with the child’s own factors, for example, if the child is less than one year old but has a large inguinal hernia with recurrent impaction, this also needs to be treated.
