[GERD related respiratory symptoms: diagnosis and treatment].
Gastroesophageal reflux disease can cause respiratory symptoms. These symptoms are triggered by reflux events that reach the pharynx, causing microaspiration or through vagal reflex. Respiratory symptoms can be vague and coexist with gastroesophageal reflux disease, without a real link between the two entities. To effectively treat these patients, it is important tofind an association between the two diseases. Work up should include the diagnosis of reflux disease, the diagnosis of pharyngeal reflux events--microaspiration--and, if possible, of laryngeal injury. Once the diagnosis has been established, an effective therapy must be offered to the patient. In these patients, medical treatment is less effective when compared to the results in the population with typical symptoms. This may be due to the fact that non-acid reflux episodes are causing the respiratory symptoms or as a result of an irreversible damage generated in the airway. Antireflux surgery is an effective therapy that reduces both acid and non-acid reflux events. This article describes the different diagnostic tests as well as the results obtained with surgical treatment in this population. Additionally, it describes potential applications of esophageal and pharyngeal impedance monitoring in these patients.
