    Abstract:
    OBJECTIVE: To compare neonatal outcomes of preterm infants (born at <32 weeks' gestation) with focal/spontaneous intestinal perforation (SIP), necrotizing enterocolitis (NEC)-related perforation, NEC without perforation or no NEC/perforation. STUDY DESIGN: Retrospective cohort study of 17,426 infants admitted to Canadian neonatal intensive care units during 2010 to 2013. The primary outcome was a composite of mortality or morbidity (bronchopulmonary dysplasia, severe retinopathy, periventricular leukomalacia or nosocomial infection). Association of intestinal perforation with neonatal outcome was evaluated using multivariate logistic regression. RESULT: SIP was present in 178 (1.0%) infants, NEC-related perforation in 246 (1.4%) and NEC without perforation in 538 (3.1%). Any intestinal perforation was associated with higher odds of the composite outcome (adjusted odds ratio (AOR): 8.21, 95% confidence interval (95% CI) 6.26 to 10.8); however, the odds were significantly lower for focal/SIP compared with NEC-related perforation (AOR: 0.29, 95% CI 0.17 to 0.51). CONCLUSION: Of the two types of intestinal perforation, NEC-related perforation was associated with the highest risk of an adverse neonatal outcome.
