Clinical Efficacy Of Ultrasound-Guided Pulsed Radiofrequency Combined With Ganglion Impar Block For Treatment Of Perineal Pain
WORLD JOURNAL OF CLINICAL CASES(2021)
摘要
BACKGROUNDGanglion impar block alone or pulsed radiofrequency alone are effective options for treating perineal pain. However, ganglion impar block combined with pulsed radiofrequency (GIB-PRF) for treating perineal pain is rare and the puncture is usually performed with X-ray or computed tomography guidance.AIMTo evaluate the safety and clinical efficacy of real-time ultrasound-guided GIB-PRF in treating perineal pain.METHODSThirty patients with perineal pain were included and were treated by GIB-PRF guided by real-time ultrasound imaging between January 2015 and December 2016. Complications were recorded to observe the safety of the ultrasound-guided GIB-PRF procedure, and visual analogue scale (VAS) scores at 24 h before and after treatment and 1, 3, and 6 mo later were analyzed to evaluate clinical efficacy.RESULTSUltrasound-guided GIB-PRF was performed successfully in all patients, and no complications occurred. Compared with pretreatment scores, the VAS scores were significantly lower (P < 0.05) at the four time points after treatment. The VAS scores at 1 and 3 mo were slightly lower than those at 24 h (P > 0.05) and were significantly lower at 6 mo after treatment (P < 0.05). There was a tendency toward lower VAS scores at 6 mo after treatment compared with those at 1 and 3 mo (P > 0.05).CONCLUSIONUltrasound-guided GIB-PRF was a safe and effective way to treat perineal pain. The 6-mo short-term clinical efficacy was favorable, but the long-term outcomes need future study.
