Background and Objective: Endoscopic discectomy method is a novel technique that is increasingly used in spine surgery. Previous studies have reported that some common complications like dural adhesions are lower in this technique compared with the other techniques. Furthermore, treatment outcomes are reportedly higher because of minimal invasion. Thepresent study aims to determine the outcome of percutaneous endoscopic discectomy.
Material and Method: A total of 130 patients underwent the lumbar disc prolapse operations during 2008 to 2012 in all of them the entire procedure was performed endoscopically. All procedures were carried out from a posterior approach using a 4-mm Hopkins 0 degrees-telescope placed in the working insert equipped with channels for suction tube, operative instruments and nerve root retractor (ENDOSPINE instrumentation (Karl STORZ GmbH and Co. KG). The pre- and post-operation pain was assessed using a Visual Analog Scale (VAS). Furthermore,   the treatment outcome was assessed using modified MacNab criteria before operation, 24 hours, one month, 2 months, 6 months, one year, and two years after operation .

Results: Good to excellent outcome was achieved in 89% of patients, which is comparable with the results of classic microdiscectomy. The mean age of patients was 35.6 years old and the mean length of follow-up was 3.4 years.  There was significant reduction in the severity of back pain and lower limb symptoms at 6 months and 2 years post-operation. There was significant improvement in all aspects of the Quality of Life scores at 6 months and 2 years post-operation. In 3 patients the dural sac was lacerated but none of the tears was exceed a few mm in length with not association with neural injury.

Conclusion: Findings of this study showed that percutaneous endoscopic lumbar discectomy is associated with improvement in back pain and lower limb symptoms.  It has the advantage that it can be performed on a day case basis with short length of hospitalization and early return to work thus improving quality of life earlier.
