What this trial studies

This observational study aims to compare esophageal manometry measurements and EndoFLIP Balloon measurements in patients experiencing dysphagia, or difficulty swallowing. It focuses on patients with known esophageal diagnoses who are referred to the GI Motility Lab at Indiana University Hospital. The study seeks to establish a registry that correlates the results of these diagnostic tests with clinical symptoms, enhancing the understanding of non-obstructive dysphagia. Both tests used in this study are FDA-approved and currently utilized in clinical practice.

Who should consider this trial

Good fit: Ideal candidates for this study are adults presenting to the GI Motility Lab at Indiana University Hospital for esophageal manometry-impedance and/or EndoFLIP.

Not a fit: Patients under 18 years old or those unable to communicate verbally with staff will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the diagnosis and management of dysphagia, leading to better treatment options for patients.

How similar studies have performed: While the use of manometry and EndoFLIP is established, the correlation between these tests and clinical symptoms in dysphagia has not been clearly defined, making this approach novel.
