Purpose of Review

The purpose of this review is to evaluate the current evidence on ultrasound-guided ilioinguinal nerve blocks for ilioinguinal neuralgia post hernia surgery.

Methods

A literature search was performed to find all relevant case reports, case series, prospective or retrospective cohort studies, and randomized controlled trials (RCTs) where ultrasound-guided or landmark-based ilioinguinal nerve blocks were used for ilioinguinal neuralgia post-inguinal hernia surgery.

Recent Findings

A total of six studies were identified with suitable data for inclusion. Three studies were retrospective, two studies were prospective, and one study was a randomized controlled trial. A total of 133 subjects were enrolled across these studies. Approximately 55–70% had a beneficial analgesic response to treatment. No major complications were reported in these studies.

Summary

Ultrasound- and landmark-based ilioinguinal nerve blocks are safe and effective for pain relief post inguinal hernia surgery. Although there were two studies that did not show a statically significant difference in both techniques, the ultrasound-guided injection has the advantage of direct visualization of pathology, more accurate needle placement, and decreased risks of intravascular injections.

疝气手术后髂腹股沟神经痛的髂腹股沟神经阻滞的回顾

审查目的

本综述的目的是评估超声引导下髂腹股沟神经阻滞治疗疝气手术后髂腹股沟神经痛的当前证据。

方法

进行文献搜索以查找所有相关病例报告、病例系列、前瞻性或回顾性队列研究以及随机对照试验 (RCT)，其中超声引导或基于标志的髂腹股沟神经阻滞用于腹股沟疝手术后的髂腹股沟神经痛。

最近的发现

总共确定了六项研究，其中包含合适的数据。三项研究为回顾性研究，两项研究为前瞻性研究，一项研究为随机对照试验。这些研究共招募了 133 名受试者。大约 55-70% 的患者对治疗产生了有益的镇痛反应。在这些研究中没有报告重大并发症。

概括

基于超声和地标的髂腹股沟神经阻滞对于腹股沟疝手术后的疼痛缓解是安全有效的。尽管有两项研究未显示两种技术在静态上存在显着差异，但超声引导注射具有病理直接可视化、针头放置更准确以及血管内注射风险降低的优势。
