两种手术方法治疗腰椎间盘突出症疗效比较

目的比较显微内镜腰椎间盘髓核摘除术（MED）和开窗减压髓核摘除术（OD）治疗腰椎间盘突出症（LDH）的临床价值。方法100例腰椎间盘突出症患者按手术入路不同分为显微内镜腰椎间盘髓核摘除术（MED）组50例和开窗减压髓核摘除术（OD）组50例，观察两组术中失血量、手术时间、住院时间、神经根损伤、下肢放射痛减轻等指标。结果MED组优良率（90．0％）高于OD组（80．0％）（χ^2=3．99，P〈0．05），术中失血量、卧床时间、住院时间均少于OD组（t=2．412，t=2．498，t=2．518，t=2．416，均P〈0．05）。结论MED与开窗减压髓核摘除术近期临床效果相似，但具有切口小、组织损伤轻和恢复较快的特点。

Comparison of Lumbar disc herniation surgery by two different methods

Objective To compare the clinical value of approach of microendoscopic discectomy( MED) and open discectomy (OD) in patients with lumbar disc herniation (LDH). Methods 100 patients with lumbar disc herniation according to the different surgical approaches were divided into MED group (n =50) and OD group (n =50) , The indicators of blood loss,operative time,hospitalization time,nerve root injury,relieve sciatica were observed in two groups. Results The rate of excellent in MED group (90. 0% ) were higher than OD group (80. 0% ) (χ~2 = 3.99, P < 0. 05); The indicators of blood loss, operative time, hospitalization time in MED group were less than OD group (t = 2.412,t=2.498,<=2.518,t =2.416,all P<0.05). Conclusion Compared with OD group,MED offer a similar short-term clinical outcome,but with smaller incision,less tissue trauma and quicker recovery.
