High-resolution manometry overcomes limitations imposed by axial and radial asymmetry as well as swallow and respiration-induced movement of the upper esophageal sphincter (UES), allowing for its reliable use in evaluation of dysphagic and reflux patients. The aim of this study was to determine normative values and their variability across position, sex, age, height, weight, BMI, and volume for clinically relevant deglutitive and non-deglutitive UES parameters.

影响吞咽和非吞咽上食管括约肌测压参数的变量：对 89 名无症状参与者的研究

高分辨率测压法克服了轴向和径向不对称以及吞咽和呼吸引起的上食管括约肌 (UES) 运动所带来的限制，使其能够可靠地用于评估吞咽困难和反流患者。本研究的目的是确定临床相关的吞咽和非吞咽 UES 参数的标准值及其跨位置、性别、年龄、身高、体重、BMI 和体积的变异性。
