Impedance Manometry

The Bravo pH test is commonly used to help confirm the diagnosis of acid flux or to identify the cause of various symptoms such as heartburn, chest pain, chronic cough, asthma, and other throat symptoms.

In patients with symptomatic GERD, manometry of the esophageal body can identify a mechanically defective (lower esophageal sphincter) LES and evaluate the adequacy of esophageal peristalsis and contraction amplitude.

Esophageal Manometry Studies have become an essential tool in the preoperative evaluation of patients before antireflux surgery, guiding selection of the appropriate procedure based upon the patient’s underlying esophageal function and excluding patients with achalasia who can be misdiagnosed with gastroesophageal reflux when clinical and endoscopic parameters alone are used for diagnosis.
