摘　　要：目的：评价经皮激光椎间盘减压术（Semiconductor Percutaneous Laser Disc Decompression,PLDD）治疗椎间盘源性腰痛的疗效。方法：对我院采用SPLDD治疗d的56例进行回顾性分析。经皮激光椎间盘减压术（PLDD）治疗椎间盘源性腰痛56例（70个椎间盘）,每只椎间盘需激光能量如下：L3～4、L5～S1为：1 200～1 400J;L4～5为1300～1500J。比较手术前后疼痛强度数字等级（pain intensity numerical rating scale,PI-NRS）评分,进行疗效观察和评定术后根据症状缓解程度。结果：随访3月为（2.1±0.4）分（与术前比较,P〈0.05）;本组56例病例中,PI-NRS评分由术前平均（8.0±0.3）分改善到术后（2.0±0.2）,共39例,占69.6%;（9.0±0.5）分改善到术后（4.0±0.6）共17例,占30.4%。未见椎间盘炎及其他并发症发生。手术时间15～60 min,平均30 min。结论：SPLDD治疗椎间盘源性腰痛安全、有效、微创,值得推广。Objective： To evaluate curative effect of Semiconductor Percutaneouslaserdisc decom pression（PLDD） in the treatment of discogenic low back pain.Methods： Total of 6 patients with discogenic low back pain who were diagnosted by MRI and discography was included in the study.the PLDD was prformed by using the BIOTEC semiconductor laser treatment,with a power of 15W,1s-pulse duration,3-5-interval,and an energy of radiation of 1 200-1 400Jin the L3-4 and L5-S1,while 1 300-1 500J in L4-5.Curative outcomes were evaluated based on the PI-NRS（pain intensity numerical rating scale）criteria.Results： The operation time was 15-60 min（mean,30 min）.The postoperative PI-NRS was sharply decreased from 8.0±0.3 to 2.0±0.2 in 22 patients in 39patients,and PI-NRS was sharply decreased from 9.0±0.5 to 4.0±0.6 in 17 patients,which revealed that 39 patients（69.6%）reported a perfect response.,and 17 patients（30.4%）reported a good response.Conclusion： Percutaneouslaser disc decompression is a safe,effective,and minimally invasive way that can be used for patients with discogeniclow back pain.
