Objectives The first aim of this study was to elucidate the detection rate of esophagogastroduodenoscopy (EGD) in patients complaining of dysphagia with esophageal motility disorders; the second was to clarify the useful parameters of EGD associated with esophageal motility disorders. Methods Participants included 380 patients who underwent EGD before high‐resolution manometry (HRM) for dysphagia. EGD findings were investigated according to the following five parameters: resistance when passing through the esophagogastric junction (EGJ), residue in the esophageal lumen, esophageal dilation, and spastic and nonocclusive contractions. HRM diagnoses were based on the Chicago classification (v3.0). Results The percentage of abnormal EGD findings was 64.4% among patients with esophageal motility disorders, and the results differed for each esophageal motility disorder. The rate of abnormal EGD for both EGJ outflow obstruction and major disorders of peristalsis was significantly higher than that for manometrically normal subjects. On multivariate analysis, resistance when passing through EGJ, residue in the esophageal lumen, spastic and nonocclusive contraction were significantly associated with esophageal motility disorders. The sensitivity, specificity, positive predictive value, and negative predictive value of these parameters for detection of esophageal motility disorders were 75.1%, 86.6%, 84.8% and 77.8%, respectively. Conclusion Esophagogastric junction outflow obstruction and major disorders of peristalsis can be screened with EGD. Among several endoscopic parameters, resistance when passing through EGJ, residue in the esophageal lumen, spastic and nonocclusive contraction are considered significantly useful indicators.
