Gliederung

Text

Objective: Chronic post hernia pain is a common complication after inguinal herniorrhaphies. Perpheral nerve field stimulation (PNFS) and spinal cord stimulation (SCS) are two new promising treatment modalities. Four patients with persistent neuropathic post-hernia pain were recruited for this prospective study.

Methods: Simultaneous electrodes were inserted into the epidural space of the spinal canal and into the subcutaneous tissue in the inguinal region (Octrode and Quatrode, respectively, St. Jude Medical). During a 14-day trial, double blind stimulation was performed via an external stimulator; 3 days over the spinal electrode, 3 days over the inguinal electrode, 3 days over both, and 5 days off, with an alternating order from patient to patient. During the trial, pain intensity was assessed thrice daily by the visual analogue scale. Additionally, pain intensity and quality of life (QOL) were assessed before and after surgical intervention by the Brief Pain Inventory, SF36 scale and the Pain Disability Index.

Results: All patients had a marked pain reduction during the trial phase, and this reduction was more prominent when both electrodes were activated simultaneously (p<0.001). At the late follow-up, a significant pain reduction and improvement of QOL was observed in 3 patients.

Conclusions: Both SCS and PNFS are effective in treating post-hernia pain, but the magnitude of pain reduction was more prominent with concomitant stimulation. Simultaneous PNFS and SCS should be considered for patients with a less than optimum response to either SCS or PNFS. More studies are necessary to address the cost-effect issues of this new approach to treatment.
