Purpose

To compare the outcomes of microendoscopic discectomy and open discectomy for patients with lumbar disc herniation.

Methods

An extensive search of studies was performed in PubMed, Medline, Embase, Cochrane library and Google Scholar. The following outcome measures were extracted: visual analogue scale (VAS), Oswestry disability index (ODI), complication, operation time, blood loss and length of hospital stay. Data analysis was conducted with RevMan 5.0.

Results

Five randomized controlled trials involving 501 patients were included in this meta-analysis. The pooled analysis showed that there was no significant difference in the VAS, ODI or complication between the two groups. However, compared with the open discectomy, the microendoscopic discectomy was associated with less blood loss [WMD = −151.01 (−288.22, −13.80), P = 0.03], shorter length of hospital stay [WMD = −69.33 (−110.39, −28.28), P = 0.0009], and longer operation time [WMD = 18.80 (7.83, 29.76), P = 0.0008].

Conclusions

Microendoscopic discectomy, which requires a demanding learning curve, may be a safe and effective alternative to conventional open discectomy for patients with lumbar disc herniation.
