BACKGROUND: There are no data of reference values on 24-hour multichannel intraluminal impedance and pH (pH-MII) monitoring in Argentinian populations.
OBJECTIVE: Our aim was to obtain the normal values of pH-MII variables among healthy asymptomatic volunteers in a metropolitan Health Care Center of Argentina, and to compare them with data already published from other regions around the world.
METHODS: A cross-sectional study was undertaken in a tertiary referral center in Buenos Aires. We enrolled healthy subjects and asked them to undergo esophageal pH-MII 24hours monitoring. pH-MII variables were recorded and described.
RESULTS: Median reflux events was 20.5 (25-75%, 95%) interquartile range: (14-46, 50) and proximal reflux episodes was 2.5 (0-10, 11). Sixty percent were acid reflux episodes: 12 (5-29, 38), representing a relatively low value when compared to those reported in European, American and Chinese populations.
CONCLUSION: Our study shows the first reference of normal values of gastroesophageal reflux in an Argentinian population. We found a total number of reflux events and a total number of proximal reflux events lower than what was reported until this date by other authors.
