BMI, body mass index; POEM, peroral esophageal myotomy; HRM, high-resolution manometry; LESP, lower esophageal sphincter pressure; UESP, upper esophageal sphincter pressure; IRP, integrated relaxation pressure; GERDQ, gastroesophageal reflux disease questionnaire; △Eckardt score = preoperative Eckardt score - postoperative Eckardt score. △LESP = preoperative LESP - postoperative LESP. △IRP = preoperative IRP - postoperative IRP.

Values are presented as n, median (interquartile range), mean ± SD, or n (%).
