SCS is widely used in treatment of various chronic pain syndroms. Much less attention is paid to SCS using for relief of acute pain, since it is not financially beneficial and there are many different effective alternative methods. We would like to bring to your attention a nonstandard clinical case of a patient, who underwent SCS in order to relieve acute pain in the anogenital zone, resulting from surgery for ovarian cancer.
In early postoperative period patient noticed the appearance of acute pain in anogenital region. In connection with absolute ineffectiveness of conservative therapy, non-standard decision was made that contradicted the basic rules of neuromodulation. Epidural electrode was implanted on the conus medullaris region to perform SCS. Implantation of electrode for sacral stimulation is not advisable, due to the lack of data on the effect of electrical stimulation on the course of the oncological process.
In postoperative period, the neurostimulation parameters were picked up, as a result of which, 60% pain regression was achieved. Patient underwent continuous neurostimulation, resulting for sustained regression of pain syndrome. After removal of electrode, no pain in anogenital region was noticed. Achieving the analgesic effect allowed further chemotherapy for cancer treatment.
The mechanisms for relieving pain in this patient remain unclear to us. Neuromodulation may help to relieve acute pain, in case of ineffectiveness or impossibility of using standard treatment options. We will be grateful to colleagues who will express their opinion on this clinical case and share their experience in similar patients treatment.
