Esophageal manometry is clinically indicated for the evaluation of nonobstructive dysphagia (i.e. dysphagia in the absence of a mechanical esophageal obstruction identified on endoscopy or radiography) [7]. Manometry is also indicated in the evaluation of gastroesophageal reflux disease (GERD), particularly prior to antireflux surgery to exclude achalasia and assess the adequacy of peristalsis. Manometry is also utilized to identify the transnasal distance to the esophagogastric junction (EGJ) for subsequent positioning of an esophageal pH or pH‐impedance probe. Further, manometry may be useful in other clinical scenarios such as in the evaluation of noncardiac chest pain, the evaluation of regurgitation (if achalasia is suspected or to support a diagnosis of rumination syndrome), and symptom evaluation following antireflux or achalasia surgery.
