The manometry with water-perfused or solid-state catheters is the predominant diagnostic procedure to detect motility disorders of the esophagus. Another method is the manometry using gas-perfused catheters. Although the high-resolution manometry is the method of first choice, the conventional manometry with helium has some advantages: the simple and hygienically unproblematic use and the absence of any artefacts by the perfusion medium compared with water-perfusion, and the considerably lower costs compared with the solid-state catheters. Every method has own normal values because of the specific pressure transmission and the design of the catheter probes. To our knowledge, normal values for gas-perfusion manometry of the esophagus have not yet been published.The esophageal manometry with helium-perfused catheters was performed in 30 healthy volunteers. The main parameters of the esophageal motility and the lower esophageal sphincter were analyzed by liquid and bolus-like swallows and compared with the previous published values in other manometric procedures.The values of the motility in the distal esophagus are consistent; the pressure of the lower esophageal sphincter is generally lower than with other methods. The distal wave amplitude and the propagation velocity are significant higher in the distal esophagus than in the middle. The perfusion medium is well tolerated by the investigated volunteers.
使用水灌注导管或固态导管进行测压是检测食管动力障碍的主要诊断方法。另一种方法是使用气体灌注导管进行测压。尽管高分辨率测压是首选方法，但传统的氦气测压有一些优点：使用简单且卫生方面没有问题，与水灌注相比，灌注介质不会产生任何伪像，并且与固态导管相比成本要低得多。由于特定的压力传导和导管探头的设计，每种方法都有自己的正常值。据我们所知，食管气体灌注测压的正常值尚未公布。对30名健康志愿者进行了氦气灌注导管食管测压。通过液体和团块样吞咽分析食管动力和食管下括约肌的主要参数，并与之前其他测压方法中公布的值进行比较。食管远端的动力值是一致的；食管下括约肌的压力通常低于其他方法。食管远端的波幅和传播速度明显高于中部。所研究的志愿者对灌注介质耐受性良好。
