Introduction

Lumbar juxtafacet cysts are benign lesions that grow at the level of facet joints or within neighboring structures. Recently, there is an ongoing trend toward less invasive procedures for treating degenerative spine diseases. Here, we report a multicenter study of full-endoscopic surgery for juxtafacet cyst removal.

Methods

We prospectively collected patients with a diagnosis of lumbar juxtafacet cyst, surgically treated in three institutions, between January 2017 and August 2019. Patients of any sex and age were eligible if they had a single level unilateral lumbar juxtafacet cyst, invalidating radicular pain lasting more than six weeks, adequate imaging, and failed percutaneous or conservative treatment. Age at diagnosis, sex, preoperative, postoperative, six-month leg pain, surgical and medical complications, spine instability (preoperatively and at 6-and 12-months), and follow-up time were collected.

Results

Thirty-five patients were enrolled. Median operative time was 78 minutes, and mean leg pain went from a preoperative value of 6.8 (SD = 1.2) to a postoperative value of 3.4 (SD = 1.1, p-value < 0.001) to 2.1 (SD = 1.7, p-value < 0.001) at 6 months. At a median follow-up of 15 months, approximately 89% of patients were pain-free or improved. We had two recurrences of radicular pain, treated conservatively. Only two surgical complications (6%) occurred: two small dural tears, both resolved without further intervention.

Conclusion

full-endoscopic surgery is feasible and safe for juxtafacet cyst removal. Our results are consistent with findings from recent full-endoscopic and series, with outcomes overlapping those reported for open or tubular techniques.

全内窥镜切除腰椎旁囊肿：一项前瞻性多中心研究。

介绍

腰突囊肿是在小关节水平或邻近结构内生长的良性病变。近来，存在一种朝着减少侵入性脊柱疾病的侵入性过程的趋势。在这里，我们报道了一项全中心内镜手术切除多发性囊肿的多中心研究。

方法

我们前瞻性收集了2017年1月至2019年8月之间在三个机构进行手术治疗的诊断为腰突面部囊肿的患者。任何性别和年龄的患者均符合条件，如果他们患有单水平的单侧腰突面部囊肿，使持续持续超过六周，充分的影像学检查，经皮或保守治疗均失败。收集诊断时的年龄，性别，术前，术后，六个月的腿痛，手术和医疗并发症，脊柱不稳（术前以及在6个月和12个月时）以及随访时间。

结果

纳入了35名患者。中位手术时间为78分钟，平均腿痛从术前值6.8（SD = 1.2）变为术后值3.4（SD = 1.1，p值<0.001）至2.1（SD = 1.7，p值） <0.001）在6个月时。在15个月的中位随访中，约89％的患者无疼痛或无疼痛。保守治疗我们有两次复发性神经根疼痛。仅发生了两种手术并发症（6％）：两次小的硬脑膜撕裂，无需进一步干预即可解决。

结论

全内镜手术是可行且安全的，以去除并发囊肿。我们的结果与最近的全内窥镜检查和系列检查结果一致，其结果与开放或管状技术报道的结果重叠。
