Ileoileal intussusception and ileal stricture associated with necrotizing enterocolitis in a premature infant: report of a case.

A 630-g male infant developed presumed necrotizing enterocolitis (NEC) after fungal enteritis that resulted in subsequent fungal septicemia associated with pneumoperitoneum on the 9th day of life. Urgent percutaneous Penrose drainage was required. During the operation on the 14th day, an ileoileal intussusception and an ileal stricture were found with perforations on each oral side of the lesions. The distinction between NEC and intussusception in premature infants when they coexist can be difficult, as these conditions share common symptoms. The relation between ischemic injury and dysmotility of the intestine is also discussed. The similarity of intrauterine fetal distress and NEC in premature infants, as seen in the present case of the intussusception associated with focal NEC, suggests that mesenteric and enteric vascular ischemia could be one trigger of intussusception in neonates.
