This outpatient procedure is performed without sedation and lasts 15 min using a thin catheter through the locally anesthetized nose. The catheter incorporates an assembly for the measurement of pressure and bidirectional fluid movement (impedance) during several water swallows. The test assesses the competency of the lower esophageal sphincter (anti-reflux mechanism) and the transport function of the esophagus.

Most importantly, manometry examines for swallowing disorders of the esophagus (achalasia, distal esophageal spasm). The findings allow the doctor to individually tailor the treatment of reflux (lifestyle, medical, endoscopic or surgical therapy). Typical findings in patients with gastroesophageal reflux disease (GERD) include shortened or absent lower esophageal sphincter and impaired transport function of the esophagus.
