Schatzki's rings (SR) are a common cause of intermittent solid food dysphagia. However, their etiology is unclear.
It is possible that they are related to acid reflux, acting as a protective barrier against further reflux.
In this study, researchers from Washington, DC, USA, sought to determine whether dilation of SR affected the degree of acid reflux.
The research team assessed 20 patients.

They performed esophageal manometry and 24-hour pH monitoring of all acid inhibitory medications before and 2 weeks after esophageal dilation.
The researchers did not identify any significant differences in any of the reflux parameters measured before and after dilation.
However, there was a trend toward reduction in symptom score in all patients.
In addition, the team found a decrease in Johnson-DeMeester score, and a decrease in supine reflux time in patients with thick SR after dilation.
The team found no correlation between ring diameter and the presence or absence of reflux.
Dr George Winters’s team concluded, “Schatzki's rings do not prevent esophageal reflux, and they may act to decrease esophageal acid clearance, especially in the supine position, thereby increasing esophageal acid exposure”.
