A pediatric hernia is mainly manifested as a lump in the umbilicus or groin when the child cries or strains to stool, often without localized redness, swelling, or significant pain, and most of the lumps can disappear on their own when the child is quiet and relaxed. The occurrence of hernia is mainly related to congenital factors, inguinal hernia is mainly caused by the failure of the sphincter to close, and umbilical hernia is caused by the failure of the umbilical ring to shrink and close in time. Most of them heal gradually within one year after birth and the prognosis is generally good. If a pediatric inguinal hernia is older than one year or if an umbilical hernia is older than four years and still does not heal on its own, timely surgical treatment should be considered. Therefore, most pediatric hernias, in their early stages, only have localized masses and no other significant discomfort, but as the child grows older, the hernia sac, if increasing in size, can become embedded and strangulated and can even cause obstructive atrophy of the testicles or ovaries, which should be treated in a timely manner.
