An omphalocele is a birth defect in which the infant's intestine or other abdominal organs stick out of the belly button (navel). In babies with an omphalocele, the intestines are covered only by a thin layer of tissue and can be easily seen.
An omphalocele is a type of hernia. Hernia means "rupture.”
Causes
An omphalocele develops as a baby grows inside the mother's womb. The muscles in the abdominal wall (umbilical ring) do not close properly. As a result, the intestine remains outside the umbilical cord.
Approximately 25 - 40% of infants with an omphalocele have other birth defects. They may include genetic problems (chromosomal abnormalities), congenital diaphragmatic hernia, and heart defects.an example is Beckwith-Wiedemann syndrome.
Treatment
Omphaloceles are repaired with surgery, although not always immediately. A sac protects the abdominal contents and allows time for other more serious problems (such as heart defects) to be dealt with first, if necessary.
To fix an omphalocele, the sac is covered with a special man-made material, which is then stitched in place. Slowly, over time, the abdominal contents are pushed into the abdomen.
When the omphalocele can comfortably fit within the abdominal cavity, the man-made material is removed and the abdomen is closed.
Sometimes the omphalocele is so large that it cannot be placed back inside the infant's abdomen. The skin around the omphalocele grows and eventually covers the omphalocele. The abdominal muscles and skin can be repaired when the child is older to achieve a better cosmetic outcome.
