Abstract

Objective: In this study, we evaluated the clinical outcomes of nerve root decompression in patients with lumbar disc herniation undergoing biportal endoscopic spine surgery at our clinic. Methods: 36 patients with lumbar disc herniation were treated with biportal endoscopic lumbar discestomy at Military Hospital 121 from 01/ 2023 to 01/2024. Pre-operative  visual analog scale for back  pain (VAS) scores and the Oswestry Disability Index (ODI) were recorded and compared with the time  of discharge  and follow-up visits at 1, 3, and 6 months. Mac Nab’s criteria were evaluated at each follow-up. Results: The average follow-up period was 6.23 months, average operative time was 79.38 minutes, and average hospital stay was 4.15 days. The mean VAS score for back pain decreased from pre-operatively 7.92 to 0.51 at the final follow-up visit, and mean VAS score for leg pain decreased from 6.28 to 0.62. The average ODI score significantly improved from pre-operatively 58.46 to 8.25 at the final follow-up visit. The average excellent based on Mac Nab’s criteria were achieved in 97.22% of cases. There were no cases requiring reoperation due to incomplete decompression. No severe complications or adverse events were recorded. Conclusion: Biportal endoscopic lumbar discectomy can achieve decompression hight effect in nerve decompression with minimal invasiveness. This technique may be a feasible option for lumbar spine surgery.
