Abstract：BACKGROUND:Microsurgical discectomy and microendoscopic discectomy are effective safe methods for treatment of lumbar disc herniations. Currently, the comparative study on two kinds of microtechnology was less, and the conclusion of each study is different.
<br> OBJECTIVE:To compare the safety and effectiveness between microsurgical discectomy and microendoscopic discectomy for treatment of lumbar disc herniations using meta-analysis.
<br> METHODS:Cochrane Library, PubMed, CNKI, VIP, Web of Science and Wanfang were searched for articles published from building to November 2013. Related journals were retrieved by hand. Randomized control ed trials of microsurgical discectomy and microendoscopic discectomy for treatment of lumbar disc herniations were col ected. Qualities of included studies were evaluated using RevMan 5.2 software, and then analyzed by meta-analysis.
<br> RESULTS AND CONCLUSION:A total of 5 randomized control ed trials involving 1 430 cases were included. The results of meta-analysis indicated that no significant difference between microsurgical discectomy and microendoscopic discectomy groups was detected in the length of hospital stay [MD=-0.19 (-0.43, 0.05), P=0.13], the improvement rate of Oswestry disability index [MD=2.78 (-0.15, 5.72), P=0.06], the improvement rate of visual analogue scale [MD=1.96 (-0.29, 4.21), P=0.09] and the root injure [RR=0.20 (0.03, 1.12), P=0.07]. Compared with microendoscopic discectomy, microsurgical discectomy showed less surgical time [MD=-10.13 (-14.06,-6.21), P<0.000 01], less blood loss [MD=-24.27 (-39.45,-9.08), P=0.002], lower incidence of dural tear [RR=0.28(0.11, 0.68), P=0.005], lower risk of recurrent herniation [RR=0.34 (0.14, 0.83), P=0.02]. Above data showed that microsurgical discectomy for lumbar disc herniations was safe and effective under the same condition, but with updated technology and equipment, above conclusion is not necessarily always the same. We suggested that clinical physicians should choose a manner based on practical condition. This topic stil requires the verification of more high-quality randomized control ed trials, and the conclusion should be updated promptly.
