Exomphalos (omphalocele)

Exomphalos affects approximately 3 in 10,000 births and can arise from a number of developmental insults. The clinical outcome is dependent upon the associated structural and chromosomal anomalies and the gestation at delivery. Accurate antenatal ultrasound diagnosis and karyotyping are important and allow informed prenatal and postnatal management decisions to be made. Prenatal care and counselling should be multidisciplinary and information should ideally be given to parents regarding prognosis and outcome based on prospectively collected population-based data.
