Umbilical hernias in infants do not always require surgery; only a small portion necessitates it. Surgery is needed mainly if the child is over two years old and still has a noticeable umbilical hernia, or if the hernia's ring diameter exceeds 2 cm. In these cases, the chances of natural healing are slim, and surgical intervention to remove the hernia sac and repair the abdominal wall defect may be necessary. In other cases, 80% of umbilical hernias can heal by the age of two as the abdominal muscles strengthen and develop with age, often causing the hernia ring to narrow and close on its own, achieving healing without any additional treatment. The previously used method of compressing the hernia with a hernia belt has been proven ineffective and is no longer employed.

Difference between umbilical hernia and abdominal linea alba hernia

Umbilical hernias occur when the hernia sac protrudes through the navel ring, commonly developing around the navel area. Linea alba hernias occur between the xiphoid process and the navel, in the area referred to as the linea alba. The hernia that protrudes in this specific region is called a linea alba hernia. Anatomically, these two types of hernias are distinct, so they can be identified based on their anatomical location. Additionally, color ultrasonography can be used to detect the position of the hernia sac. If it is located in the upper abdomen, above the navel, it is generally identified as a linea alba hernia. If it is situated above or below the navel, it may be considered an umbilical hernia. Ultrasound can help differentiate between an umbilical hernia and a linea alba hernia.

Is there no belly button after umbilical hernia surgery?

Umbilical hernia refers to a protrusion formed by abdominal cavity contents through the umbilical ring, commonly seen in infants and young children. Most umbilical hernias can heal on their own within the first year as the umbilical fascial ring gradually contracts. Therefore, non-surgical treatment is mostly adopted to promote healing. However, if the child is over two years old and the diameter of the umbilical hernia exceeds 1.5 centimeters, surgical treatment is recommended. After umbilical hernia surgery, the belly button is still preserved. The surgery generally involves making a small incision at the lower edge of the navel, freeing the hernial sac, repositioning the hernial contents, and after partially excising the hernial sac at the umbilical ring, suturing is performed.

The difference between umbilical hernia and umbilical protrusion

Umbilical hernia refers to a condition in children where the umbilical ring does not close during development, causing a defect in the abdominal wall. This situation can be treated conservatively. Within half a year, the effects are generally good. You can choose a coin larger than the umbilical ring or cover it with a flat board, press it against the umbilical ring, and then use adhesive tape to fix it to prevent movement. Generally, most patients can heal on their own. If the diameter of the umbilical ring still exceeds 1.5 cm after two years old, it is advisable to actively accept surgical treatment. Moreover, the protrusion may not involve a defect in the abdominal wall but a potential weakness in the abdominal wall at the navel. Under conditions of increased abdominal pressure, there can be a protruding appearance at the navel. The biggest difference from an umbilical hernia might be that the umbilical protrusion might present a lump that does not completely disappear. In the case of an umbilical hernia, if the contents can be returned to the abdominal cavity, the hernia can disappear completely.

Is hot compress useful for umbilical hernia?

In cases of umbilical hernia, applying heat generally has no effect. For infants, it is often acceptable to observe conservatively until the child is about two years old. Adhesive tape therapy can be used in this period. By the age of two, the umbilical ring in most children will close on its own. For those over two years old with an umbilical ring diameter still greater than 1.5 cm, surgery should be considered. For patients over five years old, it is generally recommended to undergo surgery sooner rather than later. In adults, the causes of umbilical hernias are mainly due to factors such as pregnancy, excessive fat in the greater omentum, chronic coughing, cirrhosis with ascites, etc., which increase abdominal pressure. Incarceration can occur, involving either the greater omentum or the small intestine, and surgery is usually the chosen treatment method, either through traditional tissue repair techniques or open tension-free hernia repair. In some cases, laparoscopic umbilical hernia repair may be chosen when necessary.

Why does the baby's umbilical hernia make a sound when pressed?

When pressing on a baby's umbilical hernia, a sound may be heard, primarily because the contents of the hernia are the intestines, most commonly the small intestine. Digestive fluids and gases are present in the intestines, so when pressed, the movement of gas through the digestive fluid can easily produce a sound, which is normal. The occurrence of an umbilical hernia in babies is mainly due to the incomplete development of the abdominal wall muscles and the umbilical ring not being fully closed. This allows internal organs like the intestines and mesentery to protrude through the umbilical ring, leading to symptoms of an umbilical hernia. After the appearance of an umbilical hernia, most children's hernias close on their own within the first year, with only a minority requiring surgical treatment.
