Abstract
Background
Esophageal motility disorders are sometimes misdiagnosed on endoscopic examination. We aimed to identify the proportion of patients with esophageal motility disorders missed during endoscopy and their clinical characteristics.
Methods
Patients diagnosed with either disorder with esophagogastric junction outflow obstruction or major disorders of peristalsis using high-resolution manometry in our hospital from April 2015 to March 2021 were included in this study. Missed esophageal motility disorders were defined as patients with any endoscopic misdiagnosis such as normal esophagus or esophagitis within 1 year before the manometric diagnosis. We determined the proportion of missed esophageal motility disorders and identified independent predictors of missed esophageal motility disorders using multivariate analysis.
Results
A total of 41/273 esophageal motility disorders (15.0%; 95% confidence interval 11.3–19.7%) were missed during endoscopy within 1 year before manometric diagnosis. In the stepwise logistic regression analysis, the following variables were selected as independent variables for patients with missed esophageal motility disorders during endoscopy: non-dilated esophagus (odds ratio = 4.87, 95% confidence interval: 1.81–13.12, p = 0.002), the presence of epiphrenic diverticulum (odds ratio = 8.95, 95% confidence interval: 1.88–42.65, p = 0.006), the use of transnasal endoscopy (odds ratio = 4.71, 95% confidence interval: 1.59–13.92, p = 0.005), and the combined use of esophagram (odds ratio = 0.023, 95% confidence interval: 0.0025–0.20, p = 0.0008).
Conclusions
Based on retrospective analysis, 15% of esophageal motility disorders were missed during endoscopy. Understanding the clinical characteristics of missed esophageal motility disorders could help improve endoscopic diagnoses.
