Radiological findings associated with the death of newborns with necrotizing enterocolitis
Abstract Objective: The aim of this study was to identify radiological and clinical risk factors for death in newborns with necrotizing enterocolitis. Materials and Methods: This was a retrospective cohort study, based on radiological examinations and medical charts of 66 infants with necrotizing enterocolitis, as confirmed by a finding of intestinal pneumatosis (stage IIA, according to modified Bell’s staging criteria). Radiological and clinical variables were evaluated. Results: Of the 66 infants evaluated, 14 (21.2%) presented pneumatosis in the large and small bowel; 7 (10.6%) presented air in the portal system; and 12 (18.2%) died. Bivariate analysis revealed that the following variables were associated with death: bowel perforation; pneumatosis in the large and small bowel; air in the portal system; earlier gestational age; longer time on mechanical ventilation before the identification of pneumatosis; and longer time on mechanical ventilation before discharge or death. In the multivariate regression, the following variables remained as predictors of death: pneumatosis in the large and small intestines (odds ratio [OR] = 12.4; 95% confidence interval [95% CI] = 1.2-127.4; p = 0.035), perforation (OR = 23.2; 95% CI = 2.2-246.7; p = 0.009), and air in the portal system (OR = 69.7; 95% CI = 4.3-[not calculated]; p = 0.003). Conclusion: The set of factors most strongly associated with death in infants with necrotizing enterocolitis comprised extensive pneumatosis, pneumoperitoneum, and air in the portal system. Our findings confirm the importance of radiological imaging in the diagnosis and monitoring of necrotizing enterocolitis.
