Purpose: The purpose of the study was to describe the incidence, epidemiology, and survival of infants with small bowel atresia/stenosis in New South Wales (NSW) and the Australian Capital Territory (ACT), Australia. Methods: A population-based cohort study was conducted of infants diagnosed with small bowel atresia/stenosis in NSW and the ACT from 1992 to 2003. Data were obtained from the prospectively collated NSW and ACT Neonatal Intensive Care Units' data collection. Individual risk factors for mortality were assessed using the χ² test. Results: The incidence of small bowel atresia/stenosis in NSW and the ACT was 2.9 per 10,000 births. Of 299 infants identified with small bowel atresia, 13 were stillborn. Of the 286 live born infants, most (52%) were delivered preterm (<37 weeks' gestation) with an 87% survival, whereas 48% were term with a 98% survival. More than half the infants (54%) had an associated birth defect. The overall mortality was 8%. Prematurity and low birth weight were identified as independent risk factors for mortality (P<.001).
