High‐resolution impedance manometry parameters enhance the esophageal motility evaluation in non‐obstructive dysphagia patients without a major Chicago Classification motility disorder

Abstract

The EII ratio and BFT appear to offer an improved diagnostic evaluation in patients with non-obstructive dysphagia without a major esophageal motility disorder. Bolus retention as measured with the EII ratio appears to carry the strongest association with dysphagia, and thus may aid in the characterization of symptomatic patients with otherwise normal manometry.
