Esophageal manometry is a motility (movement) study of your esophagus (or food pipe), which is a long muscular tube that connects the throat to the stomach. The lower oesophageal sphincter (LOS) lies at the lower end of the esophagus which meets the stomach, and helps to prevent stomach contents like acid from backing up into the food pipe (referred to as acid reflux).
This test can be useful to help diagnose certain health conditions or disorders that is related to the esophagus, such as achalasia, scleroderma or diffuse esophageal spasm. It can also be conducted prior to surgery for reflux disorders and in evaluations of patients with chest pain not associated with heart disease.
The purpose of this test is to check if the muscles and nerves in your esophagus are working well and measures the muscle contractions that occur in the esophagus when you swallow. It also measures the coordination or force of your esophageal muscles food that moves food along into the stomach. Overall, it helps to evaluate how well your esophagus is performing.
During this procedure, a local anaesthetic is sprayed to your nose and throat to numb the nasal area. A small thin tube will be inserted through your nose into your esophagus. This tube contains special tiny pressure sensors and will accurately measure the movement and contraction of the esophagus in real-time. Once it is in place, you may be asked to remain seated or lie your back on an exam table. You will then be made to swallow a few sips of salt water while pressure recordings are taken to check your swallowing function, the strength, pressure and pattern of your esophageal muscle contractions. The tube is slowly withdrawn once the test is done, which lasts about 30 minutes.
There is minimal risk to this procedure, and the process is the same as inserting a feeding tube. Except that in this case it will be removed once the study is done. You may experience some discomfort and slight soreness during the test, in your nose and throat as well as watery eyes.

The results of the esophageal manometry can be received in one to two days, which can be a part of a pre-operative evaluation or to identify the cause of your esophageal symptoms.
