An esophageal manometry may be ordered if anti-reflux surgery is being considered, so a doctor can assess the muscular contractions of the esophagus before surgery.
An esophageal manometry is not used as an initial test for finding the cause of chest pain or esophageal symptoms. Other diagnostic tests, such as an upper endoscopy or barium x-rays, are ordered first. If these tests do not reveal a cause of symptoms, then your doctor may consider a manometry.
