A rapid-pull through technique was used to measure lower oesophageal sphincter pressure before and immediately after swallowing. Often no high pressure zone could be detected after a swallow although sometimes an attenuated pressure profile persisted, associated with weakly developed peristalsis. The persistence of normal sphincter profiles was associated with failure of peristalsis or weak peristaltic pressure waves. Overall, there was a significant drop in mean sphincter pressure after swallowing.
采用快速牵拉技术在吞咽前及吞咽后即刻测量食管下括约肌压力。吞咽后常无法检测到高压区，尽管有时会持续存在压力轮廓减弱的情况，并伴有蠕动减弱。正常括约肌轮廓的持续存在与蠕动失败或蠕动压力波减弱有关。总体而言，吞咽后平均括约肌压力显著下降。
