Pneumatosis intestinalis in children beyond the neonatal period: is it always benign?

The significance and management of pediatric pneumatosis intestinalis (PI) remains poorly defined. We sought to add clarity in children beyond the neonatal period. Pediatric patients 3 months–18 years admitted to a quaternary children’s hospital with a diagnosis of PI were included in this retrospective study. Pathologic PI was defined as irreversible, transmural intestinal ischemia. 167 children were identified with PI. Of these children, 155 (92.8%) had benign PI and 12 (7.2%) developed pathologic PI. The most common underlying diagnosis for pathologic PI was global developmental delay (75%), although we identified a spectrum of underlying diagnoses at risk for PI.
