1. With omphalocele the defect is usually much larger than in gastroschisis. 2. About 30 % of infants with an omphalocele have other congenital abnormalities. 3. If this persists after birth it is called an omphalocele . 4. Approximately 15 % of live-born infants with omphalocele have chromosomal abnormalities. 5. The second hypothesis does not explain the low percentage of associated abnormality compared with omphalocele . 6. In omphalocele , there is a defect in the development of the anterior abdominal wall. 7. Abdominal wall defects, specifically the main two types, gastroschisis and omphalocele , are rare in occurrence. 8. Additional services are usually necessary for with omphalocele and the associated chromosomal abnormalities and birth defects that also arise. 9. Medical literature reports four tetra-X pregnancies, two healthy, one with trisomy 21, one stillborn with omphalocele . 10. Omphalocele occurs when some of the organs protrude through the muscles of the abdomen in the area surrounding the umbilical cord.
