LES residual pressures with wet swallows (WS), multiple rapid swallows (MRS) and percent change after MRS. LES residual pressure (integreted residual pressure, IRP) was ≥15 mmHg with wet swallows in achalasia spectrum disorders. Percent change in LES residual pressure was more profound in subtype 3 and EGJ outflow obstruction with preserved peristalsis similar to controls (p=0.3 compared to controls). In contrast, this change was much less prominent in achalasia subtypes 1 and 2 (p≤0.02 compared to controls).
