Standard manometry is still today the method of choice for investigating motor disorders of the esophagus. Fundamental elements in executing the test are suitable equipment, an execution technique following well established protocols and the adoption of univocal criteria for interpreting the results. In fact it is essential to use low compliance pneumo-hydraulic pumps and to perform the test in distinct steps to separately evaluate the features of the sphincter and the peristaltic activity of the esophageal body. Newly introduced technology (computerized analysis) authorizes an objective analysis of the tracing and the measurement of novel parameters, making it necessary however to re-evaluate the parameters of normalcy in the asymptomatic population. The manometric features of the lower esophageal sphincter, which define its competence (mean pressure at the point of respiratory inversion, abdominal length, total length), are probably better expressed by the mean pressure of the entire LES, by the area under the curve and by the Vector Volume. As far as motility of the esophageal body is concerned, computerized manometry provides for a more precise definition of the maximum amplitude of the esophageal contractions and an objective measure of their duration.
如今，标准测压法仍是研究食管运动障碍的首选方法。进行该测试的基本要素包括合适的设备、遵循既定方案的执行技术以及采用明确的标准来解释结果。实际上，使用低顺应性气液泵并分步骤进行测试以分别评估括约肌的特征和食管体的蠕动活动至关重要。新引入的技术（计算机化分析）允许对记录进行客观分析并测量新参数，但这也使得有必要重新评估无症状人群的正常参数。下食管括约肌的测压特征决定了其功能（呼吸反转点的平均压力、腹段长度、总长度），可能通过整个LES的平均压力、曲线下面积和向量容积能更好地体现。就食管体的运动而言，计算机化测压能更精确地定义食管收缩的最大幅度，并对其持续时间进行客观测量。
