Association of reflux symptom index scores with gastroesophageal flap valve status

Endoscopic grading of GEFV is a simple and useful technique which may provide an accurate diagnosis of laryngopharyngeal and gastroesophageal reflux. Also, reflux symptom index (RSI) is a simple, economic and noninvasive diagnostic tool for gastroesophageal reflux. However, in this research, we did not find any correlation between reflux symptom index and degree of esophageal mucosal injury which was classified according to LA classification.
