Understanding Esophagometry: A Diagnostic Tool for Esophageal Conditions
An esophagometer is a medical device used to measure the diameter of the esophagus, which is the tube that carries food from the throat to the stomach. It is typically used to diagnose and monitor conditions such as esophageal stricture (narrowing) or cancer.
The esophagometer consists of a flexible tube with a balloon at one end. The tube is inserted through the mouth and into the esophagus, where the balloon is inflated to press against the walls of the esophagus. The diameter of the esophagus is then measured using a pressure sensor or a series of marks on the tube.
Esophagometry can be performed as a diagnostic test to evaluate symptoms such as difficulty swallowing, chest pain, or regurgitation of food. It can also be used to monitor the effectiveness of treatments for conditions such as esophageal cancer or stricture disease.
