New study aims to unravel swallowing mysteries in reflux patients
NCT ID NCT07365046
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will use a special test called high-resolution manometry with impedance to closely examine how the throat and esophagus work during swallowing in 160 adults with swallowing difficulties or suspected extraesophageal reflux. Participants will also undergo 24-hour pH monitoring to measure acid exposure. The goal is to better understand swallowing problems and reflux, not to test a new treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could lead to better diagnostic methods for swallowing disorders and extraesophageal reflux.
- What could go wrong
- This is an observational diagnostic study, not a treatment trial. It may not directly improve patient outcomes, and results may not apply to all patients.
