Core Tip

Core tip: The normal esophageal mucosa creates a protective epithelial barrier that might be impaired in patients with non erosive reflux disease (NERD). Whereas endoscopy and pH monitoring are the most important diagnostic tools in the diagnosis of NERD, recent studies suggest that esophageal biopsies might have a complementary role. Particularly in the differential diagnosis between NERD and functional heartburn, the application of histological severity scores showed very promising results. Further evaluation of the scores could lead to routine application of histology in specific NERD populations.
