The clinical and radiographic features of five sick premature infants with
idiopathic hypertrophic pyloric stenosis are presented. Clinical features
were nonspecific, the common findings being recurrent nonbilious emesis,
persistent abdominal distention, and the inability to place a nasojejunal
feeding tube through the pylorus. Plain abdominal radiographs demonstrated
persistent gastric dilatation in four of the infants. Idiopathic
hypertrophic pyloric stenosis should be considered in the differential
diagnosis of premature infants with upper gastrointestinal tract symptoms.
