经皮激光椎间盘减压术(PLDD)及其改良术式治疗腰椎间盘突出症

Treatment of Lumbar Disc Herniation by Percutaneous LASER Disc Decompression(PLDD) and Modified PLDD

目的比较研究经皮激光椎间盘减压术(PLDD)及其改良术式治疗腰椎间盘突出症,评估PLDD改良术式的临床疗效。方法回顾性分析比较应用Nd:YAG激光进行常规单点髓核照射汽化19例和改良多点小能量髓核激光照射120例的治疗效果。结果通过12～24个月随访,对二者的疗效进行比较。二种不同的治疗方法产生了显著不同的疗效。参照改良MacNab手术评价标准,常规PLDD术组19例,疗效优2例,良10例,差7例,有效率63%。改良PLDD术组120例,疗效优52例,良50例,差18例,有效率85%。结论经皮激光椎间盘减压术减压效果好、安全性高、并发症少、术后康复快、术后复发率低。改良经皮激光椎间盘减压术治疗腰椎间盘突出症的疗效明显优于常规经皮激光椎间盘减压术,减少二次手术机会及其造成的痛苦,提高了手术的安全性,大大降低了手术和住院费用,是适合我国国情的腰椎间盘突出症的微创手术方法。

Objective To study the micro-invasive operative method and to compare the effect of treatment of PLDD and modified PLDD for Lumbar Disc Herniation. Methods Vaporized part of the nucleus pulposus in single or multiple point after acupuncture into lumbar disc, to reach the purpose ofthe decompression ofthe lumbar disc. Results Among the 19 cases of the regular PLDD group, the excellent and good rate was 63%, and among the 120 cases of the modified PLDD group, the excellent and good rate was 85%. Conclusion The modified PLDD has good effect on the treatment for lumbar disc herniation.
