Esophageal Manometry
Esophageal manometry is a diagnostic test that measures the pressure and function of the esophagus muscles. It is often used to assess swallowing disorders, acid reflux, and chest pain by evaluating the coordination and strength of the esophageal contractions.
Overview
Esophageal manometry uses a narrow, flexible catheter with pressure sensors to measure the contractions and function of the esophagus. The catheter is inserted through the nose and passed down to the stomach. The patient is asked to swallow water at different intervals, allowing the doctor to assess how well the esophageal muscles work.
Purpose of the Procedure
Esophageal manometry evaluates the strength and coordination of esophageal muscles, helping to diagnose swallowing disorders, chronic acid reflux, and conditions like achalasia and esophageal spasms.
How to Prepare
For esophageal manometry, patients are required to fast before the procedure. Antacids and medications that affect esophageal motility should be avoided. The test is typically performed without sedation, and patients may need to briefly stop medications used for acid reflux.
What to expect after
After esophageal manometry, patients can immediately return to normal activities, including eating and drinking. A mild sore throat or nasal discomfort may persist for a few hours, but no lasting effects are expected.
Complications & Risk
Esophageal manometry has minimal risks, but patients may experience mild discomfort, gagging, or nasal irritation during catheter insertion. Rare complications include nosebleeds, esophageal perforation, or infection. In rare cases, the test may trigger chest pain or spasms.
Results and Follow-up
Esophageal manometry results are available immediately after the test. The provider explains how well the esophageal muscles function and whether motility disorders are contributing to symptoms. Treatment may involve medications, lifestyle adjustments, or further diagnostic tests.
