What are the benefits of Endoscopic Discectomy?
The purpose of this study was to evaluate technical problems, complications, and overall initial results of endoscopic discectomy in treatment of a single lumbar disc prolapse.

Overview of Literature:
Since standard discectomy had been used to treat lumbar intervertebral disc prolapse, many modifications and new surgical techniques such as microdiscectomy, and transforaminal endoscopic discectomy have been used. Minimizing surgical trauma to posterior spinal tissues was achieved by posterior interlaminar endoscopic approach.
Materials and methods: Forty three patients with single level lumbar disc prolapse treated with endoscopic discectomy were included. METRx system (Medtronics) was used in all patients. Pain was evaluated one day, one month, 6 months and one year post procedure using 10-point Visual analogue Scale (VAS). Paired t test was used for parametric data. Wilcoxon signed rank tests were used for non-parametric data. Chi-Squared was used for qualitative variables. P value <0.05 is considered significant.

The mean follow up was 29 months (range 12 months –48 months). Open surgical conversion was required in one patient with suspected large dural tear with root prolapsed before discectomy. Minor dural puncture occurred in another case in early practicing time. The average surgical time was 82 min. (range54-93 min.). Average blood loss was 20- 65 ml. The mean hospital stay in this series was 15 hours (range 8 hours- 24 hours). 93% of patients had good-to-excellent results.

Endoscopic discectomy using METRx system provides many benefits such as a small skin incision, reduced postoperative pain, shorter hospital stay, faster mobilization, shorter rehabilitation, reducing pain medication usage, quick recovery to daily life or work, as well as surgeon’s comfortability with the standard bimanual technique. ..
