Esophageal Manometry
Esophageal manometry is a diagnostic test used to measure how well the esophagus is functioning. It specifically evaluates the rhythmic muscle contractions (peristalsis) that occur when you swallow and the coordination and force exerted by the esophageal muscles. The test also checks the lower esophageal sphincter (LES), the valve that prevents stomach acid from refluxing into the esophagus. This procedure is the "gold standard" for diagnosing motility disorders like achalasia or esophageal spasms, and it is often required before a patient undergoes anti-reflux surgery to ensure the esophagus has enough strength to handle the procedure.
During the test, a thin, pressure-sensitive tube is passed through the nose and into the esophagus. As the patient takes small sips of water, the tube’s sensors record the pressure changes and muscle patterns. While the sensation of the tube can be mildly uncomfortable, the procedure is relatively quick and provides critical data that cannot be captured by an endoscopy or X-ray alone. It allows specialists to pinpoint exactly where the "misfire" in the swallowing process is occurring, leading to a much more accurate and targeted treatment plan.
