Umbilical hernia
In different age periods the umbilical hernia is significantly different from each other, so it was decided to distinguish umbilical hernia in children and umbilical hernia in adults.
Umbilical hernia in children:
Umbilical hernia in children is a consequence of the anterior abdominal wall development defect. All the factors causing the increase of intraabdominal pressure can lead to rupture. Umbilical hernias in children occur rather often, especially among girls, usually in the first months of life.
Signs of an umbilical hernia: in an upright position and straining the child in the area of the navel protrusion appears round or oval bulla, which is usually independently set in a horizontal position at the back. If the hernia ring is broad, the hernia is easy set. In the narrow hernia ring the hernia can set difficulty that is regarded as a partial impaction. Complet impaction occur rare.
Umbilical hernia in adults:
Umbilical hernia in adults is only 3-5% of all abdominal hernias. They arise mostly in women older than 30 years, since pregnancy and childbirth weakens umbilical ring. Large hernias often have multilocular hernia sac, the contents of which may be the stomach and intestines.
The symptoms of umbilical hernia depend on its size, the size of hernia ring, severity of adhesions and associated obesity. Hernias can be set and unset, when the hernia sac and adhesions fuse with surrounding tissues.
