Abstract

Background and aim: Recently, Gastroesophageal Reflux Disease Questionnaire (GerdQ) has been developed for diagnosis of GERD. However, no study investigated its value in real-world practice. This study aimed to investigate whether GerdQ can be used for diagnosis of GERD in China.

Methods: A national multicenter survey was undertaken; all patients who underwent first diagnostic upper endoscopy for upper gastrointestinal (GI) symptoms were included. Data including the gender, age, symptoms, and endoscopic findings were prospectively recorded. The GerdQ score was measured before endoscopic procedure.

Results: Totally, 8065 patients were included. One thousand four hundred and thirty-five patients (17.8%) had reflux esophagitis. Among them, 620 (43.2%) patients' GerdQ score was ≥ 8. For 2025 patients with GerdQ ≥ 8, 620 (30.6%) were found to have reflux esophagitis, but the remaining 69.4% (1405/2025) were normal. Proportions of patients with reflux esophagitis increased in cut-off range from 3-18 for GerdQ. However, 22.2% of the patients with a GerdQ score ≤ 2 also had reflux esophagitis. Twenty-eight (0.3%) patients were diagnosed to have upper GI malignancies, and 10 out of these 28 (35.7%) patients' GerdQ score was ≥ 8.

Conclusions: The study suggests the proportions of Chinese patients with reflux esophagitis rise up with the increase of GerdQ score, and GerdQ may be used for diagnosis of GERD. However, low GerdQ score cannot exclude the possibility of reflux esophagitis. A minority of Chinese patients has high GerdQ score but is diagnosed with malignancies, even in the absence of alarm features.
