title: Esophageal motor disorders in patients evaluated for dysphagia and/or noncardiac chest pain.
abstract: During the period January, 1983-October, 1990, 429 subjects were referred for functional evaluation of dysphagia and/or noncardiac chest pain. Of these, 304 (70.8%) were shown to have some kind of esophageal motor abnormality. The most frequent motor abnormality of the esophagus was represented by nonspecific motor disorders (31%), followed by achalasia (13%), whereas the other dysfunctions accounted for a smaller percentage. In particular, diffuse esophageal spasm was shown to be quite rare. It is concluded that esophageal manometry may provide a high diagnostic yield in patients presenting with dysphagia and/or noncardiac chest pain.
