HIGH RESOLUTION ESOPHAGEAL MANOMETRY
High Resolution Esophageal Manometry
Esophageal manometry is a test that is used to measure the function of the lower esophageal sphincter (the valve that prevents reflux, or backward flow, of gastric acid into the esophagus) and the muscles of the esophagus. This test will tell if your esophagus is able to move food to the stomach normally. The esophagus is a long, muscular tube that connects your throat to the stomach.
Our area of clinical expertise include:
Indications
❖ DYSPHAGIA (Difficulty in swallowing) – It is gold standard to diagnose and classify achalasia cardia.
❖ To diagnose Distal Esophageal Spasm, Jackhammer Esophagus, Ineffective esophageal motility
❖ GERD (Reflux disease) – To measure LES pressures & document Lax LES & hiatus hernia
❖ Atypical Chest Pain – To diagnose distal esophageal spasm, Jackhammer esophagus
❖ Before Fundoplication – To look for esophageal peristaltic reserve
❖ Evaluate results of medical and surgical treatment
❖ Evaluate rumination syndrome
❖ Determine lower esophageal sphincter location before a 24-hour pH study
Pre-procedure preparation:
Procedure:
At the start of the test, one nostril is anesthetized with a numbing lubricant. A thin flexible plastic tube approximately 3 mm in diameter is passed through the anesthetized nostril, down the back of the throat, and into the esophagus as you swallow. With further swallowing, the tube is passed down into the stomach and is positioned in such a way that high resolution zone lies across LES. Recordings are taken at rest in basal state & during swallows when 5 ml of water is given through mouth. Multiple swallows are tested to allow measurement of the lower esophageal sphincter (the barrier to reflux), the esophagus (the swallowing tube), and the upper esophageal sphincter (in the throat). Pressure recordings are made throughout the study. Patients can usually resume regular activity, eating, and medicines immediately after the test.
