title: Jejunal atresia secondary to intrauterine intussusception, presenting as acute perforation.
abstract: Intussusception in neonates is rare. The authors report the second case in the Western literature of neonatal intussusception presenting as pneumoperitoneum. A male infant was referred 30 hours after birth because of possible midgut volvulus after emesis and failure to pass meconium. An abdominal x-ray film revealed a large amount of free air in the peritoneal cavity. At operation a type 3 jejunal atresia was found, with a 2-mm perforation in the dilated proximal end and a viable intussusceptum just inside the distal end. The authors conclude that this case represents an atresia secondary to inutero intussusception, with perforation occurring after birth (secondary to air-swallowing and gastrointestinal secretions).
