Abstract
Introduction: Omphalocele and Gastroschisis are the two most common congenital abdominal wall (AWD) defects.
Objectives: To determine birth prevalence of Omphalocele and Gastroaquisis; to verify variations in different periods and to study the associated morbidity, mortality and survival.
Patients and Method: The database of the Latin American Collaborative Study of Congenital Malformations (ECLAMC) was searched between the years 1996 and 2010.
Results: 33 newborns (NB) with AWD were investigated (11.6 per 10,000 births). 19 of the cases corresponded to omphalocele (6.7 per 10,000 births) and 14 to gastroschisis (4.9 per 10,000 births). Children with omphalocele had significantly greater association with other malformations and the frequency in males was higher and showed higher mortality rates than gastroschisis. All children with gas-troschisis were born alive; they were predominantly female infants whose mothers were significantly younger.
Conclusion: Birth omphalocele and gastroschisis prevalence were higher than published information, perhaps due to the fact that the HCUCH (Clinical Hospital of Universidad de Chile) is a reference center. Both anomalies showed a significant increase in their birth prevalence rates when compared with those previously obtained by us in the same hospital. Significant differences between these two entities were described. Omphalocele presented higher stillbirth, mortality and fatality rates; higher frequency of associated malformations and higher average maternal age.
