About this trial
The prospective clinical trial will study muscle fibrosis in relation to lower esophageal sphincter (LES) measurements on Functional Lumen Imaging Probe (FLIP) Topography (the novel technology that utilizes impedance planimetry) after pharmacologic challenge. A better understanding of achalasia will allow intervention at an earlier stage.

Non-English speaking - the rationale is that the symptom characterization and outcome data are measured on detailed and fairly lengthy (5-7 pages) questionnaires written in English with some medical terms. These are standardized questionnaires with no short forms available.
