The best time to operate on a baby’s hernia is usually after the age of 1 year, when the risk of anesthesia is lower. However, in case of critical conditions such as impaction, emergency treatment is required. Therefore, the exact timing of surgery for a baby hernia varies depending on the condition, and there is no strict age limit. A hernia that occurs before the age of 1 year has the potential to heal on its own and usually does not require treatment if the symptoms are mild and can be closely monitored. However, if the hernia does not improve after the age of 1 year, the baby is well developed in all aspects and tolerates surgery relatively well, so surgery can be performed with less risk of anesthesia to ensure surgical safety. If the baby has a large hernia, recurrent intussusception with severe crying and pain, it is prone to complications such as intestinal necrosis and requires urgent surgical treatment. In addition, babies need to take bed rest and avoid strenuous activities after hernia surgery. At present, minimally invasive treatment is the main treatment, which is less invasive and the child recovers faster.
