ABSTRACT

We retrospectively examined the 24 hour oesophageal pH study and the upper gastrointestinal (UGI) series of 67 children aged 5 weeks to 15 years. Thirty-seven were suffering from gastro-oesophageal reflux (GER) and 27 from other diseases. Nineteen of them were younger than 6 months, 22 older than 18 months and the remaining 26 ranged from 6 to 18 month old. We found a high incidence of false positive and false negative results of the UGI series in all age groups. The number of false positive results was much higher in infants younger than 6 months (67%) than in the older children studied (27% between 6 and 18 months and 14% after 18 months). On the contrary, false negative results were absent in the first 6 months of life, but their number increased with age, up to 40% in children older than 18 months. Moreover, the 24 hour ph monitoring was found to have a high sensitivity (100%) and specificity (82-100%) in all age groups. For this reason, we believe than this examination could be used as the first line of investigation for the diagnosis of GER in all children, independently of their age.
