sometimes called Omphalocele occurs when the abdomen fails to close
around the base of the umbilical cord during the early development
of the baby.
The size of the Exomphalos depends on the number
of organs exposed. This is usually the bowel but may include the
liver and other organs.
The sac containing the exposed organs is
usually covered in a protective membrane. The abdominal cavity is
sometimes smaller in Exomphalos children due to the organs growing
externally. In about 30% of cases Exomphalos occurs in conjunction
with other birth defects.
