title: Recurrent pneumatosis intestinalis in young infants.
abstract: In 67 infants with necrotizing enterocolitis (NEC) at Children's Hospital of Michigan from 1987-1990, three had recurrent pneumatosis intestinalis (PI) after the neonatal period and after hospital discharge. All three infants were premature (26-34 weeks), and one had an additional risk factor of gastroschisis. All three had their initial episode of NEC within the first month of life. Two had bowel resections, and one was treated medically. 15 h to seven months after discharge from the hospital, all three infants developed recurrent PI at ages ranging from 2.5 to 9 months. Two of the infants had free intraperitoneal air. Though all three infants had PI, only one had true recurrent NEC with ischemic bowel and died. This baby was the only one with rotazyme positive stools. The second infant, who had surgery for gastroschisis, had incomplete obstruction secondary to adhesions resulting in PI. Since surgery this infant has thrived. The third infant had extensive PI of the colon with free air. At surgery there was no evidence of bowel perforation. The free air was attributed to rupture of one of the many colonic cysts of PI. Subsequently, the child has done well. Recurrent PI in infants who have had NEC is unusual and the causes are varied. Because more neonates are surviving NEC, the pediatric radiologist needs to be aware of this delayed complication.
