An increasing prevalence of extraesophageal complications of gastroesophageal reflux (GER) has been seen. Evaluation of clinical profiles of patients submitted to prolonged esophageal pH monitoring could help to identify the patients who could benefit from the early diagnosis of GER. To evaluate the population, indications and results of esophageal pH-monitoring for the diagnosis of GER in a pediatric gastroenterology clinic. Data from 190 children and adolescents who had esophageal pH-monitoring were analyzed. A descriptive analysis of the population was performed and the children were categorized in five groups according to the age. The equipment used was a Digitrapper MKIII (Synetics) and all data were analyzed by using a software EsopHogram 5.7. Reflux index was established for analysis. The most frequent indications for the exam were: asthma (26.8%), apnea/cyanosis (20%), recurrent pulmonary infections (18.4%), wheezing infant syndrome (15.8%) and chronic cough/horseness (11%). The most frequent groups of age for the respiratory symptoms were: asthma--above 5 years (92.2%); apnea/cyanosis--under 3 months (55.3%); recurrent pulmonary infections and wheezing infant syndrome--3 to 12 months (31.4% and 83.3%). Reflux index of patients with positive exam for GER was significantly higher in patients under 2 years than above 2 years of age. Respiratory symptoms were predominant among the indications for esophageal pH-monitoring in children. The knowledge of the clinical profile of the patients who had esophageal pH monitoring could help to improve the technical quality of the exam.
