Esophageal motility study

Esophageal motility study (also known as an esophageal manometry) is a medical procedure used to measure the function of the esophagus and lower esophageal sphincter. It is often performed when patients present with symptoms such as dysphagia (difficulty swallowing), chest pain, or gastroesophageal reflux disease (GERD).

Procedure

The esophageal motility study involves the insertion of a thin, flexible tube (catheter) through the nose, down the esophagus, and into the stomach. The catheter is equipped with sensors that can measure pressure changes in the esophagus and lower esophageal sphincter. These measurements can help identify abnormalities in esophageal function.

Indications

Esophageal motility studies are often performed when patients present with symptoms such as dysphagia, chest pain, or GERD. They can also be used to diagnose conditions such as achalasia, a disorder characterized by difficulty swallowing due to a lack of normal esophageal contractions, and esophageal spasm, a condition in which the muscles of the esophagus contract abnormally.

Results

The results of an esophageal motility study can provide valuable information about the function of the esophagus and lower esophageal sphincter. Abnormal results may indicate conditions such as achalasia, esophageal spasm, or gastroesophageal reflux disease (GERD).

Risks

As with any medical procedure, there are potential risks associated with esophageal motility studies. These may include discomfort or pain during the procedure, nosebleeds, or a sore throat afterwards. However, serious complications are rare.
