The determination of pH at this level in healthy volunteers also has a good reproducibility.

A new pH catheter for laryngopharyngeal reflux: Pseudo-reflux events were defined as a drop in pH on the proximal electrode lower to pH 4. However, it underestimates the distal reflux that it is possible to study by means of the method of the present paper. Moreover, it does not seem to be important differences between studies in western or eastern populations Abnormal acid exposure was considered as abnormal when DeMeester score value was above Also, to as in the present study there are not significant differences related to age or sex 5.


The acidity of certain foodstuffs may affect oesophageal pH recording by overestimating the number of reflux episodes 15,16but its real impact is small 1,9,17, Variability of pressures with age and frequency of “abnormal” contractions.

Twenty-seven subjects had abnormal conventional pH. Dig Dis Sci ; 50 As noted, the reflux in the proximal oesophagus is rare and available normal values vary widely among different laboratories whatever the point of placement of the recording electrode.

Although it is on asymptomatic subjects, we found abnormal pH monitoring at the distal level in 27 out of subjects with valid studies They usually take place at night and are characterised by a drop in pH in the upper oesophagus independently of the presence of acid in the lower oesophagus manometriia Fig.


Dig Dis Sci ; 54 For the study of patients with extra-oesophageal syndromes, different placements of the pH electrode have been employed: Los 91 voluntarios restantes H; media de edad: Os testes foram realizados de acordo com as normas da Sociedade Brasileira de Pneumologia e Tisiologia.

Procedure and experimental design A national multi-centre study was carried out including 18 centres in Spain. Servicio de Aparato Digestivo. Gastroenterology ; 2: Statistical analysis The results of the different parameters are expressed as median, range and 95th percentile. The protocol for the study was approved by the Ethics Committees of each of the participating centres and all participants gave written informed consent.
