Answer

Esophageal manometry evaluates esophageal motor pattern, contraction amplitude, and LES pressure and function. [5, 6] The manometric criteria for diagnosis of the primary esophageal motility disorders are shown in the images below:

Normal manometry results show normal esophageal bo Normal manometry results show normal esophageal body peristalsis with normal lower esophageal sphincter (LES) pressure and relaxation. The LES pressure tracing is at the level of the sleeve (tracing 6).
Achalasia manometry picture Note the nonrelaxing l Achalasia manometry picture Note the nonrelaxing lower esophageal sphincter (LES) and the absence of esophageal body peristalsis. The LES pressure tracing is at the level of the sleeve (tracing 6).
Manometry demonstrates diffuse esophageal spasm wi Manometry demonstrates diffuse esophageal spasm with simultaneous contractions of the esophagus observed throughout the tracing. The lower esophageal sphincter (LES) pressure tracing is at the level of the sleeve (tracing 6).
