Esophageal atresia is a congenital malformation incompatible with life. The incidence is quite variable in Chile and all over the world. Objective: To estimate the prevalence at birth of esophageal atresia, comparing with previously published data. Patients and Methods: All children with congenital anomalies born at the UniversityofChile Clinical Hospital from 1999 to 2009 were included. Results: 19.312 births during the study period were registered, 1710 of them had a congenital anomaly (8,9 %). Fifteen of the malformed newborns had esophageal atresia (7.8 x 10.000): one stillbirth and 14 alive newborns. 78,6% of cases were discharge alive from the hospital, 3 (21,4 %) died during the hospitalization. Only 1/15 was an isolated esophageal atresia, 6 cases were syndromic and 9 were classified as VACTERL association. Prenatal diagnosis was made in 73,3 % of the cases. Newborns with esophageal atresia had significantly less birth weight, less gestational age and more malformed relatives, than control newborns. Metrorrhagia during pregnancy in mothers was more frequent in cases than controls. No difference in maternal age between groups was founded. Conclusion: The esophageal atresia prevalence at birth was higher than previously reported local data, and lower than the rest of ECLAMC data; this could be explained because the University of Chile Clinical Hospital is a reference Hospital for prenatal diagnosed cases.
