Functional Luminal Imaging Probe (FLIP) Topography Use in Patients With Scleroderma and Trouble Swallowing

Not Recruiting

Trial ID: NCT03270722


FLIP topography has been FDA cleared to evaluate a variety of esophageal conditions, but has never been evaluated in patients with scleroderma. The investigators hope to evaluate this technology in patients who have scleroderma and various esophageal symptoms, and compare to non-scleroderma patients.
