Commonly, in clinical practice an automated analysis of pH-MII tracings is obtained.
Adult patients aged 18 - 80 years old;
pH-MII performed off PPI
Prior upper GI endoscopy indicative of structural disease (except for oesophagitis or hiatal hernia).
Incomplete pH-MII (less than 21 hours recording);
Ph-MII performed on PPI
Suboptimal quality of the tracings preventing interpretation in clinical practice;
All patients referred for pH-MII are eligible.
