The most accurate methods for diagnosing reflux esophagitis are gastroscopy and pH monitoring. Gastroscopy allows direct visualization of the esophagus, enabling clear identification of inflammatory lesions, bleeding, erosion, or other symptoms, making it a relatively direct approach for confirming reflux esophagitis. pH monitoring involves continuous measurement at the lower end of the esophagus over 24 hours; if the pH value falls below the standard threshold, it suggests the possible presence of reflux esophagitis.
