title: Dysphagia: evaluation and treatment.
abstract: The evaluation of dysphagia begins with a careful history, which usually points to the underlying cause in up to 80% of cases. The goals of the history are to distinguish oropharyngeal causes from esophageal causes of dysphagia and to distinguish mechanical from motor disorders of the esophagus in those patients with esophageal dysphagia. Evaluation typically begins with a videofluoroscopic examination in patients with oropharyngeal dysphagia and begins with a routine barium swallow or upper GI endoscopy in patients with esophageal dysphagia. Esophageal manometry may be an adjunct to the evaluation of patients with esophageal dysphagia, particularly to confirm specific motor disorders, such as achalasia. The management of functional causes of dysphagia is supportive and empiric given the lack of well-controlled treatment studies in this heterogenous group of patients.
