We use a CT scan or X-ray to determine the exact location of the nerves. During a plexus coeliacus permanent block you will be positioned on your back, while a splanchnic nerve treatment requires you to lie on your stomach.
Different treatment forms
After numbing the skin, your surgeon will place a needle near the nerve ganglion. We will use imaging to ensure that the right position has been found. Once the needle is in position, one of the following procedures will follow:
- A test block: your surgeon will administer a local anesthetic which will numb the plexus coeliacus or splanchnic nerves for up to 24 hours. This will help us measure the effects a permanent plexus coeliacus block will have without causing permanent effects;
- A, alcohol neurolysis: a procedure involving phenol or alcohol administered through the needle, which will damage the nerves and block them from transmitting pain signals;
- Burning (Radiofrequency Ablation - RFA) the nerves using electrodes which will heat up the nerves up to 80 degrees celsius for 4 minutes which will damage them and block them from transmitting pain signals.
Effects
The effects of a neurolysis or RFA procedure can last for weeks or months. Most people will not need general anesthetics, although we can give you something to calm you down if you prefer.
Observation
We will keep you for observation at a recovery ward. You will not have to spend the night at the hospital after a test block or RFA, although we recommend not driving or biking after the procedure.
After a neurolysis, you will need to spend several hours laying down and stay at the hospital for one night for observation. After a consultation with the pain specialist or anesthesiologist the following morning, you will be able to go home.
