Esophageal Manometry

What is an esophageal manometry?

An esophageal manometry is a test that gauges how well the esophagus works by measuring the muscle contractions and muscle strength of the esophagus when swallowing.


An esophageal manometry may be utilized to effectively diagnose conditions including:

  • Heartburn: A type of indigestion that feels like a burning sensation in the chest. This sensation is the result of acid reflux.
  • AchalasiaAchalasia is a rare disease in which the muscles located in the lower portion of the esophagus are unable to relax. As a result, food cannot pass into the stomach and causes chest pain and regurgitation of ingested food and liquids.
  • Scleroderma: This term is used to describe a group of rare diseases that encompass hardening and tightening of the skin and connective tissues in the body.
  • Dysphagia: Dysphagia is a difficulty in swallowing that may result in pain.

What to expect during the procedure

During an esophageal manometry, a thin, flexible tube containing sensors, known as a catheter, is gently guided through the nose, down the esophagus and into the stomach. Patients are required to remain still and take slow, smooth breaths and take small sips of water as the catheter measures the pressure, strength and pattern of the muscles contracting in the different parts of the esophagus. A computer connected to the catheter records the results, which the physician will then review.

This procedure takes approximately 30 minutes, and patients are able to resume normal activity.
