摘　　要：目的研究河南省正常成人的食管运动功能。方法用消化道压力检测仪检测３８名健康成人食管不同部位的压力。结果食管上、下括约肌的静息压分别为４．７８±２．０５ｋＰａ和２．５６±１．２５ｋＰａ。食管上段、中段和下段的静息压分别为０．７１±１．１５ｋＰａ、０．６８±０．４９ｋＰａ和０．６３±０．５９ｋＰａ。食管原发性蠕动波的平均传播速率在食管上括约肌至食管上段为５３．８９ｍｍ·ｓ－１，上段至中段为２２．１３ｍｍ·ｓ－１，中段至下段为４０．３２ｍｍ·ｓ－１，下段至下括约肌为１５．０６ｍｍ·ｓ－１。结论食管各部位的压力值及原发性蠕动波的传播速率明显不同，食管的两端存在高压区。Objective To study the esophageal motility in normal adults of Henan province.Methods Esophageal pressures of 38 healthy volunteers were meassured by a manometer.Results The resting pressure of upper and lower esophageal sphincter were 4.78±2.05kPa and 2.56±1.25kPa.The mean resting pressures of upper, middle and lower segments of esophgus were 0.71±1.15kPa,0.68±0.49kPa and 0.63 ±0.59kPa.A mean propagation speed primary waves were 53.89mm·s -1 from upper esophageal sphictor to upper segment of esophagus, 22.13mm·s -1 from upper to middle segment,40.32mm·s -1 from middle to lower segment, and 15.06 mm·s -1 from lower segment to low esophageal sphictor. Conclusion The pressures and the propagation speeds of primary waves in the esophagus are different in the different segments of esophagus.There are high zones in proximal and distal portion of the esophagus.
