Esophageal body response to MRS in achalasia spectrum disorders. In patterns with aperistalsis (subtypes 1 and 2), there was complete failure of peristalsis, with varying proportions of panesophageal pressurization. In subtype 3 and incomplete EGJ outflow obstruction, 80% of subjects had a contractile response to MRS, and proportions of peristaltic patterns were similar between the two groups. In the control group a contractile response was seen in >90% of subjects.
