Assessment

Primary outcomes

comparison of difference in upper and lower esophageal epithelium of esophageal barrier function by mini ussing chamber system among patients of PPI-resistant NERD, functional heart burn and healthy volunteer.

Key secondary outcomes

1. comparison of esophageal barrier function between patients with heart burn (PPI-resistant NERD and FH) and healthy volunteer.
2. comparison of esophageal tight junctional protein in the bisopy specimen among PPI-resistant NERD, FH and healthy volunteer.
3. validation of esophageal histopathological difference amaong PPI-resistant NERD, FH and healthy volunteer.
4. elucidating relationship with intraesophageal luminal pH and esophageal epithelial barrier function between PPI-resistant NERD and FH.
5. comparison of difference in esophageal reflux contents and epithelial barrier function between PPI-resistant NERD and FH
