Pyloric Stenosis in Preterm Identical Twins of a Triplet Birth with a Review of Pyloric Stenosis in Premature Neonates

Pyloric stenosis occurs in 1 of every 200-300 live births and is four times more common in males than in females. Reports of pyloric stenosis in premature neonates are rare. We present a case of pyloric stenosis in premature female identical twins of a triplet birth whose father also had pyloric stenosis. The incidence of pyloric stenosis in premature infants and in identical twins, the age and manner of presentation and the clinical courses of these infants is presented. The potential mode of genetic inheritance is also reviewed.
