Abstract
To examine a possible esophageal basis for cervical symptoms, we studied 63 patients with persistent cervical complaints, 36 patients with gastroesophageal reflux but no cervical symptoms, and ten normal subjects. Patients were evaluated for a history of pyrosis and regurgitation and underwent otolaryngologic examination, barium esophagram, upper endoscopy, esophageal biopsy, standard esophageal manometrics, acid reflux testing, and Bernstein examination, as well as tests of esophageal dysmotility and acid clearance time before and after bethanechol (50 μg/kg, two doses). Standard diagnostic examinations usually were normal in patients with cervical symptoms. Pyrosis, regurgitation, and a positive Bernstein examination were uncommon in patients with cervical symptoms. This occurred despite frequent acid reflux (68%) and poor acid clearance (79%). Esophageal dysmotility also was common (63%). Patients with reflux but no cervical symptoms and normal subjects had a normal acid clearance time, and dysmotility was unusual (8%). We conclude that patients with cervical symptoms have diminished esophageal sensitivity despite frequent and long acid exposure. The pathophysiologic significance of this observation is discussed.
