title: [Clinical value of intraesophageal pH measurement in children. Experience in 235 cases].
abstract: The intra-esophageal pH test is presented as a diagnostic method and as a control of GER, considering the 24-hour test as the best among all exploratory methods. The authors present 235 studied cases, distributed as follows: a control group of 20 normals, 24 cases explored after surgery, 80 cases of children with recently diagnoses GER or cases of bad response to postural treatment and 111 cases at the end of a favourable postural treatment. The normal quantitative values of 24-hour esophageal monitoring by pH-metry are presented in children and these are compared between the aforementioned groups. A detailed study of these explorations allows the authors to make a quantitative value of GER and to find out which ones of the studied parameters are more reliable for diagnosis (percentage of time under pH less than 4), and which ones indicate the severity of the process (refluxes of more than five minutes) that condition a change of treatment for the patient. Likewise, this study also permits the establishment of a relationship between GER and respiratory symptoms.
