Necrotizing enterocolitis is seldom observed in full-term, or near term newborns. We report on two infants born after 36 weeks of gestation who presented with necrotizing enterocolitis after surgery for gastroschisis. Both patients had been formerly weaned from parenteral nutrition and fed thereafter with hydrolyzed cows' milk protein formula. At the age of 1.5 and 4.5 months respectively, the patients presented clinical and radiological signs of necrotizing enterocolitis. Evolution was favourable under medical treatment (parenteral nutrition, progressive refeeding). Post-neonatal digestive symptoms in a child with gastroschisis should prompt the diagnosis of necrotizing enterocolitis in order to allow an early treatment.
