Congenital abdominal wall defects and reconstruction in pediatric surgery: gastroschisis and omphalocele

The embryology, epidemiology, associated anomalies, prenatal course and the neonatal and surgical care of newborns with gastroschisis and omphalocele are reviewed. For gastroschisis temporary intestinal coverage is often done before a more definitive operative closure that may be immediate or delayed. Outcomes in gastroschisis are determined by associated bowel injury. For omphalocele small defects are closed primarily while large defects are treated topically to allow initial skin coverage before a later definitive closure. Outcomes for omphalocele are determined mainly by the presence of associated anomalies.
