  4. Comparison between MD and MED in VAS, MacNab and complications: Meta-analysis

  5. 80% Life-time prevalence of back pain * Adam and Victor’s Principles of Neurology, McGrew-hill, 2009

  6. Herniated intervertebral disc Most common in lumbar lesion

  7. Lumbar Discectomy • No response to conservative Tx. for 6wks • Early, progressive neurologic symptom • Microsugicaldiscectomy (MD)Microendoscopicdiscectomy (MED)

  8. MD vs MED MD MED Less bleeding Fast tissue recovery Short hospital stay Less Postop. pain • Standard • Short op. time • Wide indication (?)

  9. Meta-analysis

  10. Weakness Process Hypothesis Strategy Collection Coding Analysis Conclusion • Qualitative research • Uneven article quality • Publication bias

  11. Method

  12. Search strategy • JAMA & Archives • PubMed • MEDLINE • EMBASE • Ovid • English • January, 2000~ September, 2010

  13. Selection of keywords

  14. Selection criteria

  15. VAS

  16. MacNab

  17. Complications

  18. Quality assessment • Type of studies • Prospective, clinical trial • Retrospective + cohort • Retrospective • Journal grade? • JAMA, NEJM, Lancet • SCI • Domestic, etc • : 1 point • : 0.8 point • : 0.6 point • : 1 point • : 0.8 point • : 0.6 point

  19. Data analysis? (분석방법) • Tools • Excel 2007, RASW statistics 18, MedCalc • Mean-difference 평균차검정? • VAS • 교차분석? • MacNab • Complications

  20. 8 VAS 8 MacNab 10 Complications

  21. 8 VAS 8 From To MacNab 14 82 10 Cx.

  22. Study characteristics

  23. Study characteristics

  24. Result

  25. VAS Baby one more time.

  26. MacNab p-value = 0.001

  27. Complications p-value = 0.962 OR(MED/MD) = 1.010 (95% CI 0.67 – 1.51)

  28. Summary

  29. VAS MacNab Cx. I don’t know No difference No difference

  30. Limitation

  31. Limited language • Changed diagnostic criteria • Uneven article quality • Publications bias • Limited patient indication?

  32. Conclusion

  33. 논문이 끝났다는 것이지.

  34. 회식은 구제역으로 어려움에 처한 축산농가를 살리기 위해서 돼지고기가 좋겠다는게 개인적인 의견이라능…
