High resolution oesophagus manometry
High resolution oesophagus manometry is an examination which charts the working of the oesophagus. Among other things, the muscle movement of the oesophagus is checked, as well as the functioning of the sphincter at the junction between the oesophagus and the stomach.
This examination gives the doctor a clearer idea of the cause of regurgitation, swallowing problems and persistent reflux symptoms. The examination is also performed as preparation for an operation in the case of a stomach rupture.
The examination takes an average of 30 minutes.
Preparation
- Inform your doctor about any medication you are taking.
- To ensure the examination goes as it should, it is important that you have an empty stomach when you come to the hospital. This means that you may not eat, drink or smoke for eight hours before the examination.
The examination
- The nurse will insert a thin probe through the nose as far as the entrance to the stomach. As this can be an unpleasant experience, the nostril is anaesthetised with a spray. This catheter cannot be fitted under a light anaesthetic as you will be asked to swallow. The doctor or the nurse checks that probe is in the correct position.
- You are asked to swallow small sips of water/salt water. This allows the doctor to observe how your oesophagus functions.
- The probe is removed. You may drink and eat.
After the examination
Although the examination provides an insight into the working of the oesophagus, the result can only be interpreted in combination with the results of the other examinations. Schedule a consultation with your referring doctor for this.
