The latter is of a stronger hold and is commonly used for larger defects in the abdominal wall. Most surgeons will not repair the hernia until 5–6 years after the baby is born. Most umbilical hernias in infants and children close spontaneously and rarely have complications of gastrointestinal-content incarcerations. [10]
By far the most common hernias (up to 75% of all abdominal hernias) are inguinal hernias, which are further divided into the more common indirect inguinal hernia (2/3, depicted here), in which the inguinal canal is entered via a congenital weakness at its entrance (the internal inguinal ring), and the direct inguinal hernia type (1/3), where ...
A paraumbilical (or umbilical) hernia is a hole in the connective tissue of the abdominal wall in the midline with close approximation to the umbilicus. If the hole is large enough there can be protrusion of the abdominal contents, including omental fat and/or bowel .
In some cases of defect either the umbilical opening is too oversized or has developed improperly which allows the organs to remain outside or to squeeze through the abdominal wall. [1] There are two main types of abdominal wall defects that result due to the changes during development. They are omphalocele and gastroschisis. Gastroschisis ...
The navel (specifically abdominal wall) would be considered an umbilical hernia if the protrusion were 5 centimeters or more. The diameter of an umbilical hernia is usually 1/2-inch or more. [ 9 ] While the shape of the human navel may be affected by long term changes to diet and exercise, unexpected change in shape may be the result of ascites .
Internal hernias occur when there is protrusion of an internal organ into a retroperitoneal fossa or a foramen (congenital or acquired) in the abdominal cavity.If a loop of bowel passes through the mesenteric defect, that loop is at risk for incarceration, strangulation, or for becoming the lead point of a small bowel obstruction.

[2] [3] Persistence of intestine or the presence of other abdominal viscera (e.g. stomach, liver) in the umbilical cord results in an omphalocele. Omphalocele occurs in 1 in 4,000 births and is associated with a high rate of mortality (25%) and severe malformations, such as cardiac anomalies (50%), neural tube defect (40%), exstrophy of the ...
Bochdalek hernias make up about 0.17% to 6% of all diaphragmatic hernia cases when they appear spontaneously in adults and about one in every 2200 to 12,500 births every year. [4] Babies who are born with a Bochdalek hernia are more than likely to have another birth defect caused by the hernia.
