目的:探讨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36例FD患者进行食管测压。结果:FD组食管下段平均蠕动收缩波幅显著低于对照组。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组出现异常蠕动波55.5％例,表现为类型不同、次数不等的双峰波、三峰波、多发重复收缩波、逆行收缩波、非传导性同步收缩波及自发性收缩波等。以双峰波最多见。7例存在两种或以上异常波,8例同时伴有食管下段低幅蠕动。本组食管体运动异常检出共86%。结论:FD患者存在食管运动功能异常,主要表现为食管体运动不协凋,其次为食管下段运动减弱。
Objective: To investigate the changes of esophageal motility in FD patients. Methods: Thirty-six patients with FD were subjected to esophageal manometry using a PC polygraf HR benchtop high resolution gas hydropneumatic capillary perfusion pressure measurement system. Results: The average amplitude of peristalsis in the lower esophagus of FD group was significantly lower than that of the control group. The incidence of lower peristalsis in the lower esophagus in FD group was significantly higher than that in the control group. There were 55.5% cases of abnormal peristalsis in FD group, which showed bimodal, trigonometric, multiple repeated contractile waves, retrograde contractile waves, nonconducting synchronous contractile waves and spontaneous contractile waves with different types and times. Most see the bimodal waves. There were two or more abnormal waves in 7 cases, and 8 cases accompanied with low peristalsis in the lower esophagus. This group of esophageal motility abnormalities detected a total of 86%. Conclusion: There is abnormal esophageal motility in FD patients. The main symptoms of esophageal dysplasia are esophageal motility and esophageal motility.
