Pediatric hernia is a congenital disease, which is mainly caused by congenital developmental abnormalities, generally including inguinal hernia and umbilical hernia, and is a common and frequent disease in pediatric surgery and hernia surgery. Generally, inguinal hernia is caused by incomplete closure of the sphincter during development, especially after birth; umbilical hernia is caused by incomplete retraction and closure of the umbilical ring after birth. Inguinal hernia in children is commonly seen in young boys, while the incidence in young girls is relatively low, with a ratio of about 10:1. Umbilical hernia is a mass in the belly button after birth, which is more obvious when crying and becomes smaller if the child does not cry or falls asleep. These two types of hernias are by far the most common in children, while femoral or hiatal hernias in adults are less common in children.
