Abstract

Objective To compare the curative effect of percutaneous endoscopic lumbar discectomy (PELD) and microendoscopic discectomy (MED) in lumbar disc herniation.Methods A literature search was performed in PubMed, Web of Science, Embase, Wanfang, CNKI. Two authors reviewed all articles individually. The methodological quality of RCTs was assessed by the Cochrane risk of bias tool, and the quality of retrospective studies was evaluated by the modified Newcastle-Ottawa scale. The data was extracted by the Review Manager 5.30.Results A total of 19 articles were brought into this Meta-analysis. The outcomes were divided into primary outcomes and secondary outcomes. Excerpt for the short-term VAS score was lower in PELD group (P = 0.010), other index, including long-term VAS score (P = 0.120), ODI score (P = 0.260), complication (P = 0.100) and recurrence (P = 0.100), didn't had significant difference in two groups. The blood loss (P = 0.000), hospital stay (P = 0.000) and the length of incision (P = 0.000) were all superiority in PELD group. Whereas the operative time was shorter in MED group (P = 0.001).Conclusion PELD was a more minimally invasive and secure technique in lumbar disc herniation.
