[The curative effect of anti-reflux treatment in the elderly patients with laryngopharyngeal reflux and obstructive sleep apnea hypopnea syndrome and its influencing factors].

Objective:To observe the clinical curative effect of anti-reflux treatment in the elderly patients with laryngopharyngeal reflux and obstructive sleepapnea hypopnea syndrome (OSAHS) and to explore the related influencing factors. Method:The cross-sectional area of the narrowest plane in the nasopharyngeal region, velopharyngealregion, glossopharyngeal region, and hypopharynx region were measured using Spiral CT combined with Müller's experiment and computer processing system. All the elderly patients were administered with proton pump inhibitors (rabeprazole sodium, 20 mg/d) and domperidone tablets (10 mg×3/d) for 3 months. After treatment, repeat tests were performed to evaluate the therapeutic effects. Result:Before and after 3 months of treatment, significant difference was found in the total number of reflux, total reflux time, reflux symptom index and reflux symptoms scale (P<0.05), however, there's no significant difference in respiratory disorder index (P>0.05). After 3 months treatment, the cross-sectional area of those four structural regions was increased in different degrees in the patients with reduced OSAHS. However, no significant changes in the cross sectional area was observed in the patients with unchanged OSAHS. Conclusion:Anti-reflux therapy has curative effect in only 60% of the elderly patients with laryngopharyngeal reflux and OSAHS. In addition to the laryngopharyngeal reflux disease, age, BMI and medical history might be the reasons that lead to the failure of the improvement in the other 40% of the elderly patients.
