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.

Can an umbilical hernia be massaged back into the abdominal cavity?

Umbilical hernias can be massaged back into the abdominal cavity, but if the hernia suddenly becomes hard, or increases in size significantly and cannot be reduced promptly, careful observation is needed to determine if incarceration has occurred. If incarceration persists for too long, it might lead to intestinal necrosis or rupture. Generally, umbilical hernias can self-heal within six months through conservative treatment. If the diameter of the umbilical ring still exceeds 1.5 centimeters after the age of two, it is advised to opt for surgical treatment. For patients over five years old, surgery is recommended under any circumstances. In conservative treatment of umbilical hernias, the most common method involves using an object larger than the umbilical ring, such as a coin or cardboard, wrapped and fixed to the umbilical area, then secured with adhesive tape to prevent movement. Generally, this treatment method is quite effective.

What impact does an umbilical hernia have on a baby?

Umbilical hernia mainly manifests in children as a bulge at the belly button, primarily containing small intestine. If an umbilical hernia is not treated in a timely manner, it may gradually enlarge when the child cries or when intra-abdominal pressure increases, leading to more of the small intestine protruding outside of the abdominal cavity. This can potentially cause localized intestinal obstruction, impacting the child's intestinal absorption capabilities and leading to weight loss. If a significant portion of the intestine protrudes and becomes incarcerated, it could cause intestinal obstruction or necrosis, necessitating surgical removal of the necrotic intestine in a hospital.

Treatment methods for infant umbilical hernia

Infant umbilical hernia is caused by a congenital weak abdominal wall around the navel, leading to protrusion. It generally does not require special treatment methods. As long as care is taken to avoid the child's intense or prolonged crying, actively treat gastrointestinal diseases to prevent increased abdominal pressure that could lead to protrusion, no special treatment is usually necessary. This is because 80% of children with umbilical hernias will see their hernia rings gradually shrink or even close as they grow older, typically by the age of two. Surgical treatment might only be needed if the hernia ring is very large, such as more than two centimeters in diameter, or if the obvious umbilical hernia persists after the age of two.

Does infant umbilical hernia need to be treated?

Over 80% of infant umbilical hernias can heal before the age of two because, as the child grows older, the abdominal muscles gradually develop. The umbilical ring often progressively narrows and closes, so no treatment is actually needed. However, it is usually advisable to prevent the child from crying excessively and to treat any gastroenteric colds and indigestion actively and effectively, to avoid repetitive protrusion of the hernia. If the child still has a noticeable umbilical hernia after the age of two, or if the diameter of the hernia ring exceeds 2cm, it is usually difficult to heal naturally. Surgery might be required, typically involving the removal of the hernia sac and repair of the abdominal wall defect.

What are good remedies for infant umbilical hernia?

Umbilical hernia in infants is caused by congenital underdevelopment of the abdominal muscles, forming a bulge beneath the skin due to abdominal distension protruding from the umbilicus. In fact, it usually does not require special treatment. Most umbilical hernias will gradually narrow and shrink within the first year after birth as the infant's nutrition and physique improve and the abdominal muscles develop, typically leading to natural closure with a very good prognosis. In daily care, it is important to prevent the child from crying loudly, especially when the child has gastrointestinal diseases and increased intestinal gas, which should be actively treated to minimize the herniation and to reduce it back when it does protrude. With such care, the chances of natural healing increase. However, if the child is over four years old and the hernia sac is still relatively large, surgical repair might be necessary.
