The most important tests in esophageal disease are endoscopy and standard X-ray examination. The tests yield valuable information on the structure but little information on the function of the esophagus. Many disorders, however, such as oropharyngeal dyskinesia, diffuse esophageal spasm, achalasia and gastroesophageal reflux are defined by an abnormal esophageal function. In these cases tests such as cinéradiography, manometry, pH-metry and scintigraphy which quantitatively assess esophageal function are necessary. The interpretation of these tests is difficult for the following reasons. 1. Insufficient technical equipment favours false positive and false negative results. 2. Some disorders of esophageal motility exist only temporarily and may be absent at the time of examination. 3. Some disorders such as gastroesophageal reflux are quantiatively defined. Minor or transient disturbancies of esophageal motility may also be found in healthy individuals. The normal range of esophageal function is not sufficiently known in most instancies. Because of these difficulties it is advisable to perform several function tests in each individual patient and to assess the results of these tests together with the slinical symptoms, standard radiology and endoscopy.
食管疾病最重要的检查是内镜检查和标准X线检查。这些检查能提供有关食管结构的有价值信息，但关于食管功能的信息却很少。然而，许多疾病，如口咽运动障碍、弥漫性食管痉挛、贲门失弛缓症和胃食管反流，是由食管功能异常定义的。在这些情况下，诸如动态放射造影、测压法、pH测量法和闪烁扫描术等能定量评估食管功能的检查是必要的。这些检查的解读存在困难，原因如下：1. 技术设备不足会导致假阳性和假阴性结果。2. 一些食管动力障碍仅暂时存在，可能在检查时不存在。3. 一些疾病，如胃食管反流，是定量定义的。健康个体也可能发现轻微或短暂的食管动力紊乱。在大多数情况下，食管功能的正常范围尚不清楚。由于这些困难，建议对每个患者进行多项功能检查，并将这些检查结果与临床症状、标准放射学检查和内镜检查结果一起评估。
