食管功能检查在国外开展已30余年,项目很多,应用亦很广泛现将近年国外食管功能检查开展的概况介绍如下。【食管压力测定】食管测压从50年代早期应用于临床以来,已成为应用最广泛的研究和诊断食管运动功能障碍的技术。在临床上,它主要用于检查有吞咽困难、烧心和胸痛症状的病人,诊断硬皮病和观察贲门失弛症或食管弥漫性痉挛的治疗效果,还可对胃底折叠等抗反流手术的效果作出评价,也常用作食管裂孔疝的辅助诊断。目前常用的测压方法有两类,即腔内灌注导管系统和腔内微型换能器系统。灌注导管是通过导管内的水柱来传导压力,经体外换能器放大和描记等设备。现在都是采用低顺应性灌注系统。
Esophageal function tests carried out in foreign countries for more than 30 years, a lot of projects, the application is also very extensive now in recent years, foreign esophageal function checks carried out as outlined below. Esophageal Pressure Assay Esophageal manometry has become the most widely used technique for studying and diagnosing esophageal motor dysfunction since its application in the early 1950s. Clinically, it is mainly used to check the symptoms of swallowing difficulties, heartburn and chest pain, the diagnosis of scleroderma and observation of cardia or esophageal diffuse spasm of the treatment effect, but also on the fundoplication and other anti-reflux surgery Of the evaluation of the effect, but also commonly used for diagnosis of esophageal hiatal hernia. Currently there are two types of pressure measurement methods commonly used, namely intraluminal perfusion catheter system and intracavitary miniature transducer system. Perfusion catheter is through the catheter within the water column to transmit pressure, amplified by the external transducer and trace and other equipment. Now use low compliance perfusion system.
