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.

Does infant umbilical hernia require surgery?

If an infant's umbilical hernia still shows obvious protrusion after two years of age, surgery is required. Another scenario that necessitates surgery is if the diameter of the hernia ring of the infant's umbilical hernia is relatively large, such as more than 2cm, as generally, it cannot heal by itself. However, over 80% of infant umbilical hernias do not require special treatment or surgery. As age increases and nutrition is maintained, the subcutaneous tissues around the abdominal wall's umbilical hernia ring can repair and narrow, leading to healing.

The difference between infant umbilical hernia and hernia

Infant umbilical hernia is a type of hernia, which differs from general hernias as the latter encompasses a broader category including umbilical hernia, direct inguinal hernia, indirect inguinal hernia, etc. Infant umbilical hernia is caused by a congenital weakness in the abdominal wall at the navel, leading to a protrusion. Similarly, hernias are often the result of insufficient developmental thickness of the abdominal wall. Thus, when intra-abdominal pressure increases, contents such as the intestine can protrude through the hernia sac, forming a hernia. Regardless of the type, whether umbilical or otherwise, it is essential to visit a pediatric surgical department in a hospital for examination and analysis. Most umbilical hernias close as the child grows and the hernial ring narrows, usually by the age of two, and often do not require special treatment. However, surgical treatment may be necessary for a small portion of cases where the diameter of the hernial ring is larger than two centimeters or has not closed after the age of two. For hernias in other locations, if incarceration occurs, emergency surgery is needed, and surgery may still be required if the condition does not resolve spontaneously.

Nursing methods for umbilical hernia

Care methods for umbilical hernia, we need to pay attention to the following points. If during a child's intense crying or activity, the contents of the umbilical hernia protrusion are relatively large, it is important to promptly soothe the patient to avoid incarceration. Because if the incarceration lasts too long, it can lead to necrosis or even rupture of the intestine, potentially endangering the child's life and requiring emergency surgical treatment. The general conservative treatment method for umbilical hernia is to select a coin or flat plate larger than the diameter of the umbilical ring, wrap it around to press against the umbilical ring, and then secure it with adhesive tape to prevent movement. Generally, most children can self-heal within six months. If the umbilical hernia does not heal by itself after two years and the diameter of the umbilical ring is greater than 1.5 cm, surgery is recommended. In any case, if the patient is older than five years and has not healed in a timely manner, it is advisable to proactively opt for surgery as soon as possible.

Does an umbilical hernia hurt?

Umbilical hernias can be painful because they may become incarcerated or even rupture. An umbilical hernia occurs when the area has not completely closed, allowing abdominal organs, such as the omentum or intestines, to enter the hernia sac. If incarceration persists for an extended period, it can cause localized pain and even symptoms of nausea and vomiting. For umbilical hernias, we generally advocate conservative treatment within the first six months, as most patients can heal on their own. If the diameter of the umbilical ring is still greater than 1.5 cm after the age of two, we recommend surgical treatment. The conservative treatment for umbilical hernia involves using a coin or a flat board, larger than the umbilical ring, wrapped and pressed against the ring, and then secured with wide adhesive tape. This method can prevent the hernia from protruding and promote healing.

What does it look like after an umbilical hernia is healed?

After umbilical hernia occurs, if it is cured and the wound heals, there is no difference from normal. There will be no lumps protruding from the abdominal wall. In principle, surgical treatment is often required after umbilical hernia occurs, as the likelihood of natural healing is small. The surgery mainly involves a tension-free umbilical hernia repair, which includes suturing the hernia ring and generally reinforcing it externally to ensure that the hernia does not recur. After the umbilical hernia is cured, the patient's navel will be flat with no protruding lumps, and there will be no incarceration of the hernia or compression of the intestines, which could cause gastrointestinal symptoms.
