[Infant esophageal pH monitoring (author's transl)].

The authors expound their experience of the infant esophageal pH monitoring from a 100 cases statistic. The digestive radiography is necessary for the vomiting infants but the efficiency of radiology is inadequate to diagnose the reflux and particularly to give a sufficient assessment of its intensity. The esophageal pH monitoring performed during a period of 3 hours is a tremendous learning experience; is allows the clinician to take mild reflux and severe reflux into account; performed in several positions, it shows interesting variations that we can turn to account by giving the therapeutic advices. That test is innocuous, easy, little costly, easily repeated; it must have its place beside other investigations and make us advance in the knowledge of a so often found disorder development.
