Esophageal impedance helps to diagnose gastroesophageal reflux disease. assesses esophageal motility, allows to diagnose not only the presence of gastroesophageal reflux, but also to assess its nature (acid / non-acid reflux), physical composition (gas / liquid / solid content). What is the impedance of the esophagus?
Esophageal impedanceis used to diagnosegastroesophageal reflux . Esophageal impedance is a functional test of the upper gastrointestinal tract by measuring the total resistance (impedance) of reflux episodes.
Esophageal impedance: what is the test for?
The test allows you to assess whether we are dealing with acidic or non-acid reflux, it also allows for a preliminary assessment of esophageal motility. It allows you to assess the effectiveness of the swallowing and its direction.
Esophageal impedance: test procedure
Esophageal impedance allows you to track the movement of the food bolus in the physiological direction (swallowing) and retrograde (reflux phenomenon). Esophageal impedance is the insertion of a thin probe through the nose into the esophagus connected to a small recording apparatus. The device records 24 hours a day whether and how often the regurgitation of gastric contents is performed, how many episodes last, or they occur only at night. The examination takes 24 hours. After completion, you receive a description of the test and an interpretation of the result.
