In the United States, it is estimated that between 6000 and 18,000 individuals each year present with disabling pain after inguinal hernia repair. Although surgical treatment with mesh removal is one of few options available, effective alternatives to nonsurgical management are needed. The use of pulsed radiofrequency (PFR), leading to nondestructive lesions of nerve structures, has been proposed as a treatment option. To examine the evidence of treatment efficacy, a systematic literature search was made. From the databases PubMed, Embase, and CINAHL, 4 case reports were retrieved and 8 patients were included for analysis. The PFR treatment was peripheral (n = 4) and central (n = 4). Pain relief varied between 63% and 100%, the follow-up period was 3 to 9 months, and no adverse effects or complications were reported. In conclusion, the evidence base of PRF in persistent pain after inguinal herniotomy is fairly limited. Suggestions for improved research strategies are presented.
据估计，在美国，每年有 6000 至 18000 人在腹股沟疝修补术后出现致残性疼痛。尽管使用网片移除进行手术治疗是为数不多的选择之一，但仍需要有效的非手术治疗方法。脉冲射频（PFR）的使用，导致神经结构的非破坏性损伤，已被提议作为一种治疗选择。为了检查治疗效果的证据，进行了系统的文献检索。从 PubMed、Embase 和 CINAHL 数据库中检索到 4 份病例报告，纳入了 8 名患者进行分析。PFR 治疗为外周（n = 4）和中枢（n = 4）。疼痛缓解率为 63%至 100%，随访时间为 3 至 9 个月，未报告不良反应或并发症。总之，PRF 在腹股沟疝修补术后持续性疼痛中的证据基础相当有限。提出了改进研究策略的建议。
