Clinical Trial Summary

Commonly, in clinical practice an automated analysis of pH-MII tracings is obtained.

Description:

All pH-MII performed in UZ Brussel are already reviewed manually according to the Wingate con-sensus and interpreted according to the Lyon consensus. In this study, we will prospectively catego-rise the reasons for discarding reflux episodes identified by automated analysis during the manual review according to the Wingate consensus, as well as the impact on different parameters related to the interpretation of pH-MII. Based on comments received to our retrospective study, we will eval-uate possible confounders to the interpretation, including the indication for referral for pH-MII, symptom severity, use of PPI during pH-MII.
