Impedance pH & High Resolution Manometry is a test used to assess pressure and motor function of the oesophagus.
The specialist will be able to evaluate how well the muscles in the oesophagus work to transport liquids or food from the mouth into the stomach.
This test may also be used to evaluate the causes of and help diagnose conditions such as:
- Gastric reflux
- Difficulty swallowing
- Functional chest pain
- Hiatal hernia
In addition, this test may be used in pre-operative evaluation in patients who are being considered for anti-reflux surgery or to ensure proper placement of pH probes for manometry tests.
