The best age for pediatric hernia surgery is between 1-3 years old. Inguinal hernia is a common disease in pediatric surgery, mostly appearing shortly after birth or within a few months, and manifests as a reversible mass in the inguinal region. The disease can be observed after the diagnosis is clear. Since the disease has the possibility of self-healing, it is recommended to observe it within 6 months without rushing to surgery. If the mass is still repeatedly protruding and gradually increasing in size after 6 months of age, the possibility of self-healing is lost and surgery is required. If the inguinal hernia is repeatedly ingrown, early treatment should be considered.
