Topographic esophageal manometry: An emerging clinical and investigative approach

Topographic esophageal manometry utilizes an increased number of pressure s ensors and three-dimensional displays to fully reveal the pressure continuu m representing peristalsis. The techniques demonstrate that peristalsis is comprised of a chain of pressure segments, beginning at the upper esophagea l sphincter and continuing through lower sphincter aftercontraction. Topogr aphic methods have already proven useful in both research and clinical sett ings. Description of the techniques, the topographic representation of norm al and abnormal esophageal motility, and advantages of topography over conv entional manometric methods are discussed in this review.
