Gastro-esophageal RefluxNCT03306485
Post Prandial High Resolution Impedance- Manometry
An observational study of Gastro-esophageal Reflux, run by Hospices Civils de Lyon at 1 site in France.
Trial summary
Nine to 30% of the population suffers from gastro-esophageal reflux disease (GERD) - suggestive symptoms (heartburn, regurgitation, chest pain, chronic couch, sore throat). Proton pump inhibitor (PPI) is usually the first line treatment. However 20 to 60% of patients have persistent symptoms on proton pump inhibitor. Read more about this study

About this study
Official title: Evaluation of Diagnostic Performances of Esophageal Post Prandial High Resolution Impedance- Manometry (HRIM) in Patients With Gastro-esophageal Reflux Disease (GERD) Resistant to Proton Pump Inhibitor (PPI) Treatment : Pilot Study (MHR POST-PRANDIALE)
Nine to 30% of the population suffers from gastro-esophageal reflux disease (GERD) - suggestive symptoms (heartburn, regurgitation, chest pain, chronic couch, sore throat). Proton pump inhibitor (PPI) is usually the first line treatment. However 20 to 60% of patients have persistent symptoms on proton pump inhibitor. Complementary examinations are then required to determine the cause of persistent symptoms (non compliance to treatment, persistent esophageal acid exposure despite proton pump inhibitor, non acid reflux, reflux hypersensitivity, functional symptoms, rumination syndrome…). The gold standard to detect reflux episodes in patients on proton pump inhibitor therapy is 24-h ambulatory esophageal pH-impedance monitoring. Esophageal High Resolution Impedance-Manometry might help to determine gastro-esophageal reflux disease mechanisms especially when performed post prandially. Further some publications demonstrated that the number of reflux episodes detected during the post prandial period might be well correlated to the total number of reflux episodes recorded during 24 h.
The hypothesis of this study is that 1-hour post prandial esophageal High Resolution Impedance-Manometry might be useful to diagnose gastro-esophageal reflux disease and can replace in some instances 24-h esophageal pH-impedance monitoring. Therefore the aim is to compare the number of reflux episodes detected with esophageal High Resolution Impedance-Manometry performed during 1-h post prandial period to the total number of reflux episodes detected during 24-h ambulatory esophageal pH-impedance monitoring.

Correlating the number of reflux episodes detected on 1-h post prandial esophageal high resolution manometry combined and those detected on ambulatory 24-h pH-impedance monitoring performed on PPIOther
Esophageal high resolution impedance manometry (HRIM) consists of introducing a transnasal probe to record esophageal contractility (manometry), bolus transit (impedance) but also the occurrence of reflux episodes. Ambulatory 24-h pH-impedance monitoring consists of recording the occurrence of reflux episodes by introducing a transnasal catheter into the esophagus. After inserting the transnasal HRIM probe and the pH-impedance catheter, both HRIM and 24-h pH-impedance recordings are started. The patient is instructed to eat a meal that induces reflux symptoms (the patient brings his own meal). One hour the end of the meal, the HRIM probe is removed. The patient is discharged at home and the 24-h pH-impedance monitoring is continued. The patient is coming back 24-h after catheter insertion to stop the pH-impedance recording and remove the catheter.

|---|---|---|
| Patients with GERD symptoms refractory to PPI therapy | Patients with proven GERD (gastro-esophageal reflux disease) off PPI (proton pump inhibitor) (Los Angeles grade B, C or D esophagitis and/or esophageal acid exposure > 5% on pH monitoring performed off PPI).
These patients have persistent heartburn and/or regurgitation despite double dose proton pump inhibitor.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Proton pump inhibitor (PPI) is usually the first line treatment. However 20 to 60% of patients have persistent symptoms on proton pump inhibitor.

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Mar 2023; AzTrials last refreshed its copy on 28 Oct 2026.
