TITRE
Miglioramento della sensibilita della pH- metria esofagea mediante monitoraggio simultaneo del pH gastrico

TITLE
Increasing sensitivity of oesophageal pHmetry by simultaneous monitoring of gastric pH: a study in 129 children

RÉSUMÉ

La pH- metria esofagea non è in grado di evidenziare episodi di reflusso gastro- esofageo (inferiore a pH 4) in presenza di contenuto gastrico non sufficentemento acido (pH < 4).

Una doppia registrazione simultanea del pH, esofageo e gastrico, èstatu effettuata in 129 bambini. I periodi nei quali il pH dello stomaco era superiore a 4 sono stati esclusi dallo studio. Sono state confrontate le percentuali di tempo durante le quali il pH esofageo era inferiore a 4 in rapporte al tempo totale di registrazione ed al tempo corretto: in 30 pH- metrie su 129 (23.3 %) ciòha portato a modificazioni rilevanti delle conclusioni. In questa maniera, tenendo conto del tamponamento dell’aciditàgastrica, abbiamo ottenuto un aumento rilevante della sensibilitádella pH- metria esofagea.



ABSTRACT

Oesophageal pHmetry cannot reveal bouts of gastro- œsophagealreflux (lower than pH 4) unless the gastric content is sufficiently acidic (pH < 4).

A simultaneous recording of the œsophageal and gastric pH was carried out in 129 children. The intervals when the gastric pH was higher than 4 were not included in the analysis of results.

We have compared the percentage of the time when the œsophageal pH was higher than 4 with the total time of recording as well as with the corrected time, which saw the final result of 30 pH recordings out of the 129 (i.e. 23.3 %) considerably modified Thus, by taking into account the buffering action of gastric acidity, we have been able to improve considerably the sensitivity of œsophageal pHmetry.
