Demonstration the interval change of IRP between preoperative HRM and postoperative HRM. (A) Preoperative HRM revealing abnormal IRP for 4 swallows (mean, 28.5 mmHg), while the remaining 6 swallows are normal (mean, 9.66 mmHg); (B) postoperative HRM revealing normal IRP for all swallows (mean, 9.72 mmHg). IRP, integrated relaxation pressure; HRM, high-resolution manometry.
