BackgroundSignificant incidence, diagnostic difficulties, clinical relevance and therapeutic
efficacy associated with the small number of publications on the primary
esophageal motor disorders, motivated the present study.AimTo determine the manometric prevalence of these disorders and correlate them to
the endoscopic and clinical findings.MethodsA retrospective study of 2614 patients, being 1529 (58.49%) women and 1085
(41.51%) men. From 299 manometric examinations diagnosed with primary esophageal
motor disorder, were sought-clinical data (heartburn, regurgitation, dysphagia,
odynophagia, non-cardiac chest pain, pharyngeal globe and extra-esophageal
symptoms) and/or endoscopic (hiatal hernia, erosive esophagitis, food waste) that
motivated the performance of manometry.ResultsWere found 49 cases of achalasia, 73 diffuse spasm, 89 nutcracker esophagus, 82
ineffective esophageal motility, and six lower esophageal sphincter hypertension.
In relation to the correlations, it was observed that in 119 patients clinical
conditions were associated with dysphagia, found in achalasia more than in other
conditions; in relationship between endoscopic findings and clinical conditions
there was no statistical significance between data.ConclusionsThe clinical and endoscopic findings have little value in the characterization of
the primary motor disorders of the esophagus, showing even more the need for
manometry, particularly in the preoperative period of gastroesophageal reflux
disease.
