Topographic esophageal manometry utilizes an increased number of pressure sensors and three-dimensional displays to fully reveal the pressure continuum representing peristalsis. The techniques demonstrate that peristalsis is comprised of a chain of pressure segments, beginning at the upper esophageal sphincter and continuing through lower sphincter aftercontraction. Topographic methods have already proven useful in both research and clinical settings. Description of the techniques, the topographic representation of normal and abnormal esophageal motility, and advantages of topography over conventional manometric methods are discussed in this review.
食管地形测压法使用数量增加的压力传感器和三维显示来充分揭示代表蠕动的压力连续体。这些技术表明，蠕动由一系列压力段组成，始于食管上括约肌，并在收缩后持续通过下括约肌。地形测压法已在研究和临床环境中证明是有用的。本文综述了这些技术、正常和异常食管动力的地形表示以及地形测压法相对于传统测压法的优势。
