Gastroesophageal Reflux and Nonspecific Hyperreactivity of Upper Aerodigestive Tract: Possible Correlations with Otorhinolaryngological Disorders

摘要: Gastroesophageal reflux (GER), a common disorder of the upper digestive tract, is primarily caused by release lower esophageal sphincter associated with delayed gastric emptying, abnormal mucosal resistance, and increased irritative capacity refluxate [1]. A clinical classification divides GER into typical form classic pyrosis an atypical [2]. Patients respiratory symptoms fall latter atypical, or extraesophageal, that characterizes “silent” GER. [3]. In fact, initial symptomatology often characterized succession (e.g. dysphagia, foreign body sensation, chronic throat clearing, hoarseness, cough, otalgia, obstructive apnea, recurrent bronchitis pneumonia) suggest direct involvement airways.
