As there was no significant difference in improvement of diet score, dysphagia score, or quality-of-life scores between study and control groups, our results do not support the empiric use of large-diameter dilation to relieve nonobstructive esophageal dysphagia.
To our knowledge, our study is the first to provide epidemiologic data on the relative prevalence of different kinds of dysphagia among patients evaluated for presumed esophageal dysphagia at a community-based tertiary care medical center.
Further studies specifically designed to assess the impact of aggressive acid suppression to relieve nonobstructive esophageal dysphagia are warranted.
Empiric esophageal dilation with large-diameter dilators is of no benefit for patients with nonobstructive esophageal dysphagia.
Objectives: The role of empiric esophageal dilation in improving esophageal dysphagia with nonobstructive esophageal lumen is not clear.
