Disorder - Hernia, umbilical

Presenting Signs

Umbilical hernias occur usually as soft round swellings in the region of the umbilicus or navel, where there is a defect in the abdominal wall. These hernias are composed of a ring of tissue and a sac surrounding the contents that protrude through the defect. Sometimes they are found incidentally during veterinary examinations; in this case they are usually non-painful, containing only fat. Alternatively they can be large enough to allow herniated intestine or other abdominal organs to slip through the defect. This can lead to strangulation of these organs. In these cases the animal may present with abdominal pain, vomiting and signs of depression, and the skin overlying the hernia will be firm and warm.

Large congenital umbilical hernias are mostly noticed at or soon after birth but also may seem to suddenly appear in adulthood. This can be due to obesity or trauma, which increases the pressure within the abdomen and causes contects to protrude through a defect.

Breeds Affected
Abyssinian
Cornish Rex
Persian
Siamese


Treatment

Surgery: small hernias can usually easily be repaired at the time of speying. This involves trimming the margins of the small hernial ring and closing the hole. If the hernia is large and contains abdominal organs, the hernial contents are inspected, replaced into the abdominal cavity and the hernial opening is closed to prevent recurrence.
