title: Esophageal motor disorders: videofluoroscopic and manometric evaluation--prospective study in 88 symptomatic patients.
abstract: Esophageal motor disorders are best evaluated with manometry, which, however, is time-consuming and not generally available. The authors prospectively investigated the yield of videofluoroscopy in detection of esophageal motor disorders in comparison with that of manometry. Eighty-eight patients with dysphagia, globus sensation, noncardiac chest pain, or progressive systemic sclerosis underwent both manometry and videofluoroscopy at 0-32-day intervals. Videofluoroscopy was performed with one swallowing study in the upright position and up to three swallowing studies in the prone oblique position. Manometric diagnoses of achalasia (n = 15), diffuse esophageal spasm (n = 1), nonspecific esophageal motor disorders (n = 44), and adynamic esophagus (n = 9) were made. Videofluoroscopically, 87% of the patients with achalasia, the one patient with diffuse spasms, 73% of the patients with nonspecific esophageal motor disorders, and all of the patients with adynamic esophagus received a correct diagnosis, for an overall sensitivity of 80%. The radiographic specificity was 79%. The authors conclude that videofluoroscopy is a valuable and reasonably sensitive technique for screening for esophageal motor disorders.
