RESUMEN
BACKGROUND: Patients with gastroesophageal reflux disease (GERD) often suffer greatly from their symptoms. The aim of this study was to determine if there is a difference in quality of life and gastrointestinal symptom complexes between patients with purely functional complaints and patients with objective GERD. MATERIAL AND METHODS: We included all patients with typical reflux symptoms, who had a GERD examination in 2017 at our department. All patients underwent high resolution manometry, 24-h-pH-metry impedance measurement and gastroscopy. Quality of life was assessed using the Gastrointestinal Quality of Life Index (GIQLI) and gastrointestinal symptoms were rated by a symptom checklist (SCL), assessing the severity and intensity of 14 different symptoms. Based on the results of the 24-h-pH-metry impedance measurement, patients were divided into 2 groups: patients with functional reflux symptoms and patients with true GERD. These two groups were compared. RESULTS: Complete data were available in 162 patients, of whom 86 (52.2%) were objectively suffering from reflux (DeMeester score mean: 37.85; SD ± 29.11) and 76 (46.1%) had a normal DeMeester score (Mean: 7.01; SD ± 4.09). No significant difference in quality of life was found between the two groups (mean GIQLI of GERD patients: 94.81, SD ± 22.40, and mean GIQLI of patients with functional reflux symptoms: 95.26, SD ± 20.33, p = 0.988). Furthermore, no significant difference could be found in the evaluated symptoms (mean general SCL score of GERD patients: 46.97; SD ± 29.23; patients with functional reflux symptoms: 48.03; SD ± 29.17, p = 0.827). CONCLUSION: Patients with functional complaints suffer just as much from their symptoms as patients with objectively diagnosed GERD. Differentiation between gastroesophageal reflux disease and functional reflux symptoms is only possible by means of functional diagnostic testing.
