  2. There are many minimally invasive procedures such as transforaminal endoscopic spine surgery, epiduroscopy, interlaminar endoscopic spine surgery and biportal endoscopic spine surgery. • In our clinic, we are using all of these interventions, and recently we started to perform biportal endoscopic spine surgery to lumbar disc herniation and spinal stenosis surgery cases.

  3. Advantages • Wider viewing angle compared to the uniportal technique • The magnification of the surgical field is similar to that of microscopic spinal surgery.

  4. Advantages • Enable to interbody fusion

  5. Advantages No muscular damage(especially M.Multifudys)

  6. BESS Biportal endoscopic surgery2 Uniportal endoscopic surgery2 Narrow view angle Inability to do laminectomy Inability to do fusion More difficult to control bleeding • Wider viewing angle • Suitable for more indication • Need for arthroscopy and endoscopy experience • Long learning curve • Bleeding control • Total laminectomy can be done • Possibility of TLIF implantation when necessary 2.

  7. Required Equipments • Standard arthroscopy instruments • Kerrison roungers • Radiofrequency probe • Artropump • Disc forceps

  8. Learning Curve • BESS had a relatively short learning curve and the complication rate in the first period of the learning curve was reported as 10.3%. • This complication rate can also be reduced by controlling epidural hemorrhage (continuous and pressure saline irrigation).

  9. Learning Curve • In this learning curve, we used aspine model and fresh sheep spine model with preserved paraspinal muscles and. • Cost-effective and useful to improve triangulation in the endoscope.

  10. Our short case series • We perfomed this technique in 10 patients and in the first case the duration of the case was over 2 hours but as we progressed through the learning curve, It is decreasing. • We did not encounter any neurological or other complications. • Patients were discharged from the hospital on postoperative day 0.

  11. Case 1-32 Y M L5-S1 disc herniation

  12. Cleaning of dorsalsurface of laminawith RF probe

  13. Laminotomy

  14. Excision of lig.flavum

  15. Removing the herniated part of the disc

  16. L5 root and discectomy

  17. Case 2-36 F L5-S1 sequestrateddischerniation

  18. Postoperative MRI

  19. Case 3- 34 y M L5-S1 sequestrateddischerniation
