Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
Patients with EE and patients with NERD referred to the GI-outpatient clinic of the University Hospital Maastricht with an indication for diagnostic gastroscopy, as well healthy volunteers will be asked to participate in the study.

Inclusion Criteria:

  • Typical GERD-symptoms lasting for more than 6 months (recurrent episodes of heartburn or acid regurgitation)
  • abnormal pH-parameters (pathological acid exposure and/or symptom association)

Exclusion Criteria:

  • Age <18 years
  • Previous esophageal or gastric surgery
  • Severe esophageal motility disorder on manometry
  • Histological evidence of Barrett's mucosa
  • Severe co-morbidities (including cardiopulmonary disease, portal hypertension, collagen diseases, morbid obesity, coagulation disorders and co-morbidity hindering a gastroscopic procedure)
  • Use of anticoagulant or immunosuppressive drugs
  • Inability to stop medication that can influence the test results, like PPI, for at least 10 days before tests
  • Excessive alcohol consumption (>20 units per week)
  • Patients unable to give informed consent.
