In treating umbilical hernias, we need to consider both the age of the patient and the size of the hernia specifically caused. Generally, children under the age of two do not require surgery. Typically, we consider using a coin or cardboard larger than the umbilical ring, wrapping it up, pressing against the umbilical ring, and securing it with adhesive tape to prevent movement. Most can close by themselves and heal. For children over two years old, if the hernia is still larger than 1.5cm, surgical treatment should be considered. In adults, traditional tissue repair methods are generally used, or an open umbilical hernia tension-free repair. The repair can be placed in front of the muscle or can use a hernia ring filling method. For most patients, if there is an opportunity for minimally invasive treatment, laparoscopic umbilical hernia repair can be selected. This method generally involves a smaller incision and can preserve the navel, reducing the chance of incision infection, and is particularly suitable for obese patients.
