Idiopathic gastrointestinal perforation in the neonate

Spontaneous localized perforation of the gastrointestinal tract, unrelated to mechanical intestinal obstruction and with no evidence of necrotizing entrocolitis (NEC), occurred in 20 neonates. Three perforations were located in the stomach, 11 in the small intestine, and six in the colon. Maternal obstetric complications as well as prematurity and postnatal distress were common in these patients. The overall survival rate was 80%. There was no late gastrointestinal symptoms in the survivors. Whether idiopathic perforation of the gastrointestinal tract results from a localized form of NEC or from a distinct lesion of unknown etiology has not yet been ascertained. Some ideas concerning the etiology of this entity, as well as some diagnostic aspects are discussed.
