Cochrane Database of Systematic Review in minimally invasive discectomy

Potential advantages of newer minimally invasive discectomy (MID) procedures over standard microdiscectomy MD or open discectomy OD include less blood loss, less postoperative pain, shorter hospitalisation and earlier return to work.
MID may be inferior in terms of relief of leg pain, low back pain (LBP) and re-hospitalisation; however, differences in pain relief appeared to be small and may not be clinically important.
Potential advantages of MID are lower risk of surgical site infection and other infections. MID may be associated with shorter hospital stay but the evidence was inconsistent. Given these potential advantages, more research is needed to define appropriate indications for MID as an alternative to standard MD/OD 1).
