Abstract
One hundred barium meal examinations performed on infants of less than 4 months of age are reviewed. All the infants presented with vomiting as a major symptom and the diagnosis remained in doubt following the initial clinical assessment. Fifty seven per cent of the examinations showed an abnormality of which 45% were thought to be significant. Hypertrophic pyloric stenosis was demonstrated in 23 infants. Other abnormalities included hiatus hernia, gastro-oesophageal reflux, and duodenal abnormalities. The value of barium meal examinations in this group of infants is emphasised.
