经皮椎间孔镜下TESSYS技术治疗腰椎椎间孔狭窄的早期临床疗效观察

The short-term outcome of transforaminal endoscopic spine system(TESSYS) approach for lumber disc herniation or lumber spinal stenosis

目的探讨经皮椎间孔镜下TESSYS技术治疗腰椎椎间孔狭窄引发腰腿痛的短期疗效。方法选取2012年3月至2014年9月本院收治腰椎椎间孔处狭窄的患者30例,均选择经皮椎间孔镜下TESSYS技术治疗。术前、术后及末次随访时应用视觉模拟评分(VAS)评估疼痛程度,应用日本骨科协会(JOA)评分评估腰椎功能改善情况。结果术前及末次随访评分的比较所有患者术中即感觉症状明显缓解。VAS评分由术前(8.13±1.21)分减少至(2.81±1.49)分,JOA评分由术前(10.77±4.21)分升高至(26.30±3.55)分。结论 TESSYS技术治疗腰椎椎间孔处狭窄,有安全性高,具有手术时间短、出血少、并发症少、患者易接受等优点。

Objective To explore the short-term outcome oftransforaminal endoscopic spine system （TESSYS） approach for lumber disc herniation or lumber spinal stenosis. Methods Clinical data of 30 patients with low back and leg pain resulting from foramen intervertebrale stenosis were recruited into this study. These patients received TESSYS. L3-4 in 3 cases,L4-L5 in 17 cases,LS-S1 in 10 cases.The visual analogue score （VAS） and JOA was determined before the op- eration and 1, 3, 6 months after the operation. Results VAS score after surgery was decreased and the JOA score was increased compared to that before surgery. TPatients are satisfied with the results of surgery. Conclusion TESSYS approach is effective for low back and leg pain resulting from foramen intervertebrale stenosis.
