A High-Resolution Esophageal Manometry is a diagnostic procedure used to evaluate the function of the esophagus and determine the cause of various symptoms such as difficulty swallowing, chest pain, or unexplained coughing. During the procedure, a thin, pressure-sensitive tube is passed through the patient’s nose, down the esophagus, and into the stomach. As the patient swallows, the tube measures and records the pressure and coordination of muscle contractions along various points in the esophagus. The high-resolution aspect of this procedure allows for a more detailed and accurate assessment of esophageal function compared to traditional manometry, enabling physicians to identify and treat conditions like achalasia, esophageal spasm, or gastroesophageal reflux disease more effectively.
