Airway symptoms and sleeping difficulties in operated and non-operated patients with gastroesophageal reflux disease

Abstract Introduction. Anti-reflux treatment studies have not succeeded in proving a causal relationship between gastroesophageal reflux disease (GERD), airway symptoms and sleeping difficulties. In a recent follow-up study we showed that patients operated for GERD have significantly less heartburn/acid regurgitation symptoms than matched non-operated patients. These two groups probably had different degrees of reflux over a long period of time. It is thus hypothesized that operated patients would report less airway symptoms and sleeping difficulties than comparable non-operated patients. A new follow-up study of the same patients was therefore conducted. Material and methods. A total of 179 patients operated for GERD and 179 matched non-operated patients with confirmed GERD were sent the Reflux, Airway & Sleep Questionnaire (RASQ), which is a new, validated questionnaire dealing with heartburn/acid regurgitation, airway symptoms, and sleeping difficulties. Answers are given on a 7-point Likert scale and the assessment period is 1 year. Results. Response rates were 68% in both groups. Operated patients reported significantly less reflux symptoms than non-operated patients (p < 0.001). Patients in the surgery group also reported less symptoms in two subscales of the RASQ dealing with airway symptoms: Laryngopharyngitis (p = 0.04) and Bronchitis (p = 0.01). There was a tendency toward less sleeplessness in operated patients, but this was not statistically significant. Snoring was less bothersome in operated patients (p = 0.02). Conclusions. Patients operated for GERD have less heartburn/acid regurgitation symptoms and less airway symptoms than non-operated patients. The findings lend support to the hypothesis of a causal relationship between gastroesophageal reflux, airway symptoms, and sleeping difficulties.
