Aim: Esophageal multi channel intraluminal impedance-PH (MII-PH) monitoring is a new technique used for detecting the flow of fluids and gas through the esophagus, using the differences in electrical impedance between the mucosal surface, fluids, and gas that surround the catheter. The aim of this study was to determine the frequency of functional heartburn in Iranian patients with non-erosive gastroesophageal reflux disease (NERD).

Methods: In this study, 940 patients aged 11-84 years, with the chief complaint of heartburn were selected. The MII-PH monitoring was done in 215 of the patients who did not have esophageal injuries (NERD).

Results: Of the participants who filled the questionnaire, 29.4% experienced heartburn at least once a week, 24.1% had it twice daily, and 21.3% had it after each meal. The mean age of the patients with heartburn was 36.97 ± 10.8 (Range: 21- 57) years. Of the patients, 51.2% were female. MII-PH monitoring was done in 215 participants, with non-erosive esophagitis.

Esophageal acid exposure of time (EAET) was negative in 42.8% and positive in 57.2% of the NERD patients. Of the patients, 39.1% and 18.1% had functional heartburn (FH) and hypersensitive esophagus (HE), respectively

Conclusion: Functional heartburn and non-erosive gastroesophageal reflux disease are prevalent in the Iranian population. Esophageal multi channel intraluminal impedance-PH (MII-PH) monitoring is essential for discriminating functional heartburn from other types of non-erosive gastroesophageal reflux diseases.
