使用低顺应性气动液压输注系统，我们对 9 名无食道疾病史的志愿者的整个食道进行了逐厘米的绘制，以观察在 5 吨湿吞咽过程中整个食道是否存在压力对称性。我们发现食管长度在 21-25 厘米之间变化。食管低压区 (LPZ) 与食管上括约肌 (UES) 的距离 (4-8 厘米) 不同。大多数受试者的 LPZ 长度为 2-3 厘米，但低压（
Using a low-compliance pneumohydraulic infusion system, we mapped the entire esophagus of nine volunteers with no history of esophageal disease, centimeter by centimeter, to see if there was pressure symmetry throughout the esophagus during 5 mt wet swallows. We found that esophageal length varied from 21-25 cm. The esophageal low-pressure zone (LPZ) varies in distance from the upper esophageal sphincter (UES) (4-8 cm). The length of this LPZ is 2-3 cm in most subjects but low pressures (
