Gastroesophageal reflux (g.e.r.) is a very common event in children particularly in infants. Twenty-four-hour continuous esophageal pH monitoring has become the preferred test to quantify acid gastroesophageal reflux. It has a large sensitivity and specificity, but it does not allow a good prediction of esophagitis. The Authors show a computerized method to determine the area under the curve (a.u.c.) and the percentage of time at different pH levels. These parameters have shown the same sensitivity and specificity as DeMeester-Boix-Ochoa score. They directly relate the time of exposure and pH level in every reflux under pH 4 and so they suggest a better prognostic index. To improve this approach to g.e.r. we will need other studies with this method.

Abstract

Gastroesophageal reflux (g.e.r.) is a very common event in children particularly in infants. Twenty-four-hour continuous esophageal pH monitoring has become the preferred test to quantify acid gastroesophageal reflux. It has a large sensitivity and specificity, but it does not allow a good prediction of esophagitis. The Authors show a computerized method to determine the area under the curve (a.u.c.) and the percentage of time at different pH levels. These parameters have shown the same sensitivity and specificity as DeMeester-Boix-Ochoa score. They directly relate the time of exposure and pH level in every reflux under pH 4 and so they suggest a better prognostic index. To improve this approach to g.e.r. we will need other studies with this method.
