Pilot Study: Implantation of a Pudendal PNA Test Lead for Neuromodulation by the ENTRAMI Technique in Case of Chronic Perineal Pain Syndrome.
Pudendal nerve release surgery in case of pudendal impingement syndrome is well described in literature.Pudendal nerve modulation in case of chronic perineal pain is also a promising technique and some small studies exist. However, in the latter group, patient inclusion criteria are very heterogenous and so conclusions about efficacy are difficult to draw. In the surgery group, outcome results also vary between the different approaches but in general, there is room for improvement. After pudendal nerve release in chronic perineal pain syndrome, it can take up to 6 months before improvement for the patient is recorded. This is partially due to the complex chronic pain syndrome mechanism.
Nothing is known about the possible effect of early neuromodulation at the level of the pudendal nerve after his release.
Recently, two cadaveric studies were published which described a minimal invasive trans gluteal approach for pudendal nerve decompression and a pudendal electrode placement.
In the present trial, the investigators would like to combine the endoscopic trans gluteal pudendal release with pudendal neuromodulation to improve the outcome for patients suffering from pudendal impingement syndrome.
The aim is to improve the results of pain score and quality of life of patients undergoing surgery for pudendal release in case of chronic perineal pain syndrome.
