Title: [Esophageal pH-metry and gastroesophageal reflux in infants and children].
Abstract: Twenty five infants, all under 3-year-old, 16 with symptoms of gastroesophageal reflux and 9 controls, were studied by continuous pH esophageal monitoring during 18 to 24 h. The diagnostic value of several pH parameters was calculated in reference to the upper limits of normal ranges previously determined in other studies performed in similarly aged children. Sensitivity and specificity of these parameters were respectively 69 and 89 p. 100 for the time elapsed below pH 4, 44 and 100 p. 100 for the number of reflux episodes per hour, 56 and 89 p. 100 for the duration of the longest episode of reflux, and 31 and 100 p. 100 for the number of reflux episodes lasting more than 5 min. These results confirm that a percentage Of reflux time (less than pH 4) longer than 5.2 p. 100 of the total duration of pH recording has the best discriminative value. However in clinical practice 2 or 3 h postprandial pH recording have a good diagnostic value when the results are expressed using a reflux score, as in adult patients. In further studies concerning gastroesophageal reflux in infants, it is concluded that diagnostic criteria must include evidence of reflux using a discriminant pH parameter.
