Esophageal motility in the assessment of esophageal function.
Esophageal manometry assesses lower esophageal sphincter (LES) pressure and its relaxation. In addition, it detects the ability of the esophageal body to initiate a peristaltic contraction and the contraction's amplitude in response to a water bolus. The study is indicated in patients with symptoms suggestive of an esophageal motor disorder and to assist in the diagnosis of some miscellaneous disorders. The most common disorders diagnosed by esophageal manometry are the primary motility disorders, such as achalasia. Manometry is indicated in the subset of patients with gastroesophageal reflux disease (GERD) who are being considered for antireflux surgery or have symptoms after antireflux surgery.
