[Longterm pH measurement in the diagnosis of gastroesophageal reflux in children. Apropos of 20 cases].

Long duration continuous recording of esophageal pH was performed in 20 children suspected of having gastroesophageal reflux. Six pH monitoring parameters were analysed and their values compared with normal standards found in the literature. The results of pH monitoring were compared with those of upper gastrointestinal series and with oesophagoscopy, performed in all patients but one. The diagnostic utility of long duration pH monitoring is discussed, according to data in the literature.
