Analysis on curative effect of CT-guided perineal nerve pulse radiofrequency combined with ganglion impar destruction in the treatment of perineal pain

Abstract

Objective To investigate the efficacy and safety of perineal nerve pulse radiofrequency combined with ganglion impar destruction in the treatment of perineal pain. Methods A total of 18 cases of perineal pain were treated by CT-guided perineal nerve pulse radiofrequency combined with ganglion impar destruction. Before and 1 d, 15 d, 1 month, 3 months and 6 months after treatment, Visual Analogue Scale (VAS) was used to evaluate the degree of pain, Pain Disability Index (PDI) was used to evaluate severity of dysfunction, and Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality. The total effective rate of treatment was calculated, and postoperative complications were recorded, including movement and/or sensory disturbances of lower limbs, perineal paresthesia, urination and/or defecation disorders, puncture site infection and/or bleeding. Results There were significant differences before and after treatment on VAS scores (F = 201.421, P = 0.023), PDI scores (F = 178.214, P = 0.020) and PSQI scores (F = 168.241, P = 0.045). Compared with before treatment, VAS scores (t = 19.562, P = 0.002; t = 17.451, P = 0.015; t = 12.583, P = 0.026; t = 15.246, P = 0.002; t = 19.458, P = 0.000), PDI scores (t = 14.265, P = 0.004; t = 12.356, P = 0.000; t = 11.235, P = 0.032; t = 9.254, P = 0.024; t = 13.265, P = 0.003) and PSQI scores (t = 15.213, P = 0.021; t = 10.235, P = 0.003; t = 7.450, P = 0.000; t = 6.352, P = 0.002; t = 14.521, P = 0.012) at 1 d, 15 d, 1 month, 3 months and 6 months after treatment were lower than those before treatment. The total effective rate of treatment was 16/18. No adverse reactions including lower limb movement and/or sensory disturbances, perineal paresthesia, urination and/or defecation disorders, puncture site infection and/or bleeding occurred. Conclusions CT-guided perineal nerve pulse radiofrequency combined with ganglion impar destruction is safe and effective in the treatment of perineal pain.
