Background:
Esophageal motility abnormalities have been observed in patients with gastroesophageal reflux disease.
Goals:
The aim of the present study was to determine if esophageal motor disorders in patients with a positive response to the omeprazole test are related to the existence of reflux or they are concomitant findings.
Study:
A 24-hour pH monitoring and a stationary manometry were performed on 128 patients: 49 of them had normal manometry, 31 hypotensive lower esophageal sphincter, 29 motor disorder in esophageal body, and 19 hypotensive lower esophageal sphincter and motor disorder in esophageal body.
Results:
We found an association between the presence of abnormal reflux and motor disorder in esophageal body (chi test; P < 0.05). However, ineffective esophageal motility was the disorder most strongly related to reflux, whereas the hypercontractile disorders were not clearly attributed to it.
Conclusions:
Esophageal manometric abnormalities should be considered cautiously before considering a motor disorder as a consequence of abnormal reflux.
