Introduction: The close relationship between gastro-oesophageal reflux disease and sleep-related breathing disorders allows the consideration of treatment with proton pump inhibitors as a feasible alternative for patients with snoring or mild to moderate sleep apnoea syndrome. Nevertheless, the presence of gastro-oesophageal reflux in the proximal oesophagus must be identified objectively with a double channel oesophageal pH-metry.
Objective: To identify clinical data allowing the selection of patients most likely to have proximal oesophageal reflux, and, therefore, candidates for oesophageal pH-metry.
Material and method: Between January 2004 and September 2006, 121 patients were prospectively included. In these patients, a nocturnal polysomnography and a 24 hour double channel pH-metry were performed on the same day. We compared statistically the clinical data, endoscopic examination of the upper airway and the pH-metry results.
Results: A good correlation was observed between the presence of symptoms suggesting pharyngo-laryngeal acid reflux and endoscopic examination of this area (P< .009). However, the comparison between clinical data and pH-metry results was not statistically significant.
Conclusions: Clinical symptoms and endoscopic examination alone are not good tools to determine the presence of gastro-oesophageal reflux in the pharynx, in this group of patients. Its presence must be ascertained by a double channel oesophageal pH-metry.
