[Diagnostics of laryngopharyngeal form of gastroesophageal reflux disease for adults (Lithuanian clinical practice guidelines)].

The laryngopharyngeal form of gastroesophageal disease represents one of the atypical manifestations of supraesophageal gastroesophageal reflux disease characterized by morphologic and functional changes in the larynx and pharynx with the associated clinical symptoms. The article presents diagnostic algorithm (guidelines) for laryngopharyngeal form of gastroesophageal disease, elaborated by the group of Lithuanian experts in otorhinolaryngology and gastroenterology. The guidelines are based on the data of evidence-based medicine and results of the scientific studies in Lithuania. Diagnostics of laryngopharyngeal form of gastroesophageal disease has to be based on: (1) patient's complaints (permanent hoarseness, throat itching and clearing, cough, heartburn, "globus" sensation) for more than 3 months; (2) typical laryngoscopic findings (edema, erythema, roughness, hypertrophy of mucosa of the posterior glottis); (3) detection of reflux esophagitis as a subsequence of pathological gastroesophageal reflux; (4) assessment of relationship between reflux and morphological/functional changes. The guidelines are designed for the otorhinolaryngologists, gastroenterologists, and general practitioners.
