High Resolution Esophageal Manometry(HRM)

High Resolution Esophageal Manometry(HRM)

 

Overview:

High Resolution Esophageal Manometry(HRM) is used to diagnose swallowing difficulties and pain caused by structural obstructive diseases such as esophageal tumors and ulcers, chest pain caused by non-cardiac diseases, and esophageal motility disorders such as systemic sclerosis. Additionally, it can be used to measure the location of the gastroesophageal sphincter and prepare for 24-hour esophageal pH testing and evaluate difficult-to-treat gastroesophageal reflux disease at the gastroesophageal junction.

 

Features:

Patients with esophageal dysmotility may present with dysphagia, noncardiac chest pain, heartburn and/or regurgitation. After inflammatory and structural abnormalities are excluded by performing an esophagogastroduodenoscopy, high resolution esophageal manometry is often performed to assess esophageal motor function. 

 

Procedure:

High-resolution esophageal pressure testing uses a catheter with 36 sensors that is placed through the nose into the esophagus to measure your esophageal pressure using solid-state pressure sensors and draw a clear and complete esophageal pressure map. During the test, you need to lie on the examination bed and try to relax while performing swallowing tests, and the doctor and technicians observe the changes in esophageal pressure and motility displayed on the computer at the other end of the catheter. The test usually takes about 30 to 60 minutes. For patients who cannot swallow well due to partial esophageal relaxation or other issues, we will use an upper gastrointestinal endoscope to guide the placement of the catheter in the appropriate position for testing.

 

Notification:

Potential side effects: Nausea and vomiting may occur during the examination, and after the examination, there may be sore throat, nosebleeds, and nasal congestion. These side effects are mostly self-limited and will recover after rest.

Potential complications: Esophageal perforation after manometry is less than one in ten thousand cases according to current data. If perforation occurs, antibiotics will be given immediately, and a surgeon will be notified to evaluate the necessary surgical treatment.

The risks and complications listed above and below have been identified, but there may still be some risks that doctors cannot anticipate and are not listed.
