Can a paediatric hernia heal itself? Does it have to be operated?

For different types of paediatric hernia, there will be different treatments.
Umbilical hernias in infants and young children generally do not require special treatment and are mainly observed. Most will heal spontaneously at around 2 years of age, with only a few patients with large umbilical rings requiring surgical intervention.
Surgery is an effective means of curing inguinal hernias, but the timing of surgery requires a comprehensive judgement by the surgeon.
Congenital diaphragmatic hernia is caused by a congenital defect in the child’s diaphragm, and some of the abdominal organs pass through the diaphragmatic defect into the thoracic cavity, which needs to be treated surgically as soon as possible after detection.
In addition, it is usually most important for parents to observe changes in the mass and the child’s condition. If an abnormally large or hard mass is found, or if the temperature or colour of the skin in the area of the mass changes, or if the child cries abnormally, has a fever or vomits, this suggests that the hernia may be ingrown and is a critical condition for the disease and requires immediate medical attention.
