探讨功能性消化不良（ＦＤ）患者食管运动功能变化。方法：采用 ＰＣ ｐｏｌｙｇｒａｆ ＨＲ台式高分辨上消化道气液压毛细管连续灌注测压系统对４０例ＦＤ患者和２０例正常人进行食管测压。结果：ＦＤ组食管下段蠕动压低于上段蠕动压的发生率显著高于对照组；ＦＤ组食管下段平均蠕动压显著低于对照组；ＦＤ组出现异常蠕动波２１例，表现为类型不同，次数不等的双峰波、三峰波、逆行收缩波、自发性收缩波和非同步收缩波等，以双峰波最多见。９例同时伴有食管下段低蠕动压；ＦＤ组食管体部运动异常检出率为７５％。结论：ＦＤ患者存在食管运动功能异常，主要表现在食管体部运动不协调，其次为食管下段运动减弱。
To investigate the changes of esophageal motility in patients with functional dyspepsia (FD). Methods: 40 patients with FD and 20 normal subjects underwent PCPG with PC polygraf HR tabletop high resolution gas hydraulics capillary perfusion pressure measurement system. Results: The incidence of lower peristaltic pressure in the lower esophagus of FD group was significantly higher than that of the control group. The average peristalsis pressure in the lower esophagus of FD group was significantly lower than that in the control group. There were 21 cases of abnormal peristalsis in FD group, Such as the bimodal wave, three peak wave, retrograde contractile wave, spontaneous contraction wave and unsynchronized contraction wave, the most common to bimodal. 9 cases accompanied by lower esophageal low peristalsis pressure; FD group esophageal motility abnormalities were detected in 75%. Conclusion: FD patients have abnormal esophageal motility, which is mainly manifested in uncoordinated esophageal motility, followed by decreased esophageal motility.
