FIGURE 3

Examples of response to MRS in achalasia subtypes and incomplete LES relaxation (ILESR) with EGJ outflow obstruction and preserved esophageal body peristalsis. No esophageal body peristalsis or pressurization is seen with wet swallows (WS) and MRS in subtype 1. In subtype 2, panesophageal pressurization is seen with both WS and MRS. In subtype 3 and EGJ outflow obstruction, WS demonstrate spastic and normal esophageal body peristalsis, with compartmentalization of pressure between the contraction front and LES. With MRS, there is abnormal inhibition of esophageal body peristalsis, with a spastic and exaggerated peristaltic sequence in both instances. WS: wet swallows, MRS: multiple rapid swallows, EGJ outflow obstruction: incomplete lower esophageal sphincter relaxation.
