PERISTALTIC DYSFUNCTION ASSOCIATED WITH NONOBSTRUCTIVE DYSPHAGIA IN REFLUX DISEASE

An evaluation was done of 325 consecutive patients who underwent esophageal manometry to investigate the relationship between solid food dysphagia and peristaltic dysfunction in gastroesophageal reflux disease. All patients with dysphagia were endoscoped to evaluate for mechanical obstruction. Manometry was done focusing on the incidence of peristaltic dysfunction (failed peristaltic sequences or sequences characterized by foci of hypotensive peristalsis). The major finding was that the severity of manometrically demonstrated peristaltic dysfunction in reflux patients correlated with the prevalence of dysphagia. After excluding patients with esophageal rings or strictures from the analysis, the overall prevalence of dysphagia was 39% among the 157 reflux patients. Within this group, 29% of patients with minimal peristaltic dysfunction experienced dysphagia compared to 78% of patients with severe peristaltic dysfunction. We conclude that peristaltic dysfunction should be considered along with mechanical obstruction as a potential cause of dysphagia in patients with gastroesophageal reflux disease. © 1990 Plenum Publishing Corporation.
