The Value of Carlsson-Dent Questionnaire in Diagnosis of Gastroesophageal Reflux Disease in Area With Low Prevalence of Gastroesophageal Reflux Disease

摘要

Background/AimsSymptom-based diagnosis for gastroesophageal reflux disease (GERD) has been accepted in the population with high prevalence. Carlsson-Dent questionnaire (CDQ) is a standardized symptom-based diagnosis tool for GERD. The value of this tool in the population with low prevalence is unknown. The aim of this study was to determine CDQ performance for diagnosis of GERD in Thai population with low prevalence versus endoscopy or 24 hour pH monitoring.
