title: Clinical, endoscopic and manometric features of the primary motor disorders of the esophagus.
abstract: BACKGROUND
  Significant 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.
  
  
  OBJECTIVE
  To determine the manometric prevalence of these disorders and correlate them to the endoscopic and clinical findings.
  
  
  METHODS
  A 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.
  
  
  RESULTS
  Were 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.
  
  
  CONCLUSIONS
  The 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.
