Brief Summary:
PPI test;empirical trial with high-dose proton-pump inhibitors (PPIs) has been shown to be a sensitive tool for diagnosing patients with GERD. However, this diagnostic strategy has not been well established in patients with extraesophageal manifestation of GERD. In this study, we aim to see the relevance of PPI test in diagnosing GERD in patients with extraesophageal symptoms.
