目的：探讨腰椎侧后路微创椎间孔镜术中髓核摘除量与临床效果的关联性。方法随机分两组（A组，B组）比较。分析两组患者基本情况、髓核摘除体积、临床效果、腰椎曲度，椎间隙高度丢失等情况进行比较。结果两组患者髓核摘除体积比较差异有统计学意义（P＜0.05）。术后随访时，ODI评分、腰痛及双下肢痛VAS评分较术前显著提高（P＜0.05）。两组改善率比较差异均无统计学意义（P＞0.05），末次随访时两组椎间隙高度差异无统计学意义（P＞0.05）。结论腰椎侧后路微创椎间孔镜术中，摘除退变突出的责任髓核、充分解除神经根压迫即可，不必刻意追求髓核摘除量。%Objective To investigate the relationship between the size of nucleus pulposus and the clinical outcomes of discectomy through transforaminal endoscope for lumbar disc herniation. Methods The patients were randomly divided into two groups. The size of nucleus pulposus,clini-cal effect, loss of intervertebral height,lumbar curvature were compared between the two groups. The recovery rate was calculated using pre and post-operative VAS and ODI scores. Results The size of nucleus pulposus had significant difference between the two groups(P<0.05). During postop-erative follow-up,there was no significant difference in VAS or ODI recovery rate between two groups (P>0.05). The loss of intervertebral height had no significant difference between the two groups(P>0.05). Conclusion The recovery rate after transforaminal endoscope for lumbar disc her-niation is not correlated with the size of nucleus pulposus. The main target of this operation is to relieve the compression of nerve root.
