Comparing Functional Outcomes: Microdiscectomy and Endoscopic Lumbar Discectomy — A Randomized Study

Background: Surgical management of lumbar disc herniation commonly involves open microscopic discectomy or endoscopic lumbar discectomy, with ongoing debate regarding their comparative functional outcomes. Objectives: To evaluate and compare functional outcomes following open microscopic discectomy and endoscopic lumbar discectomy using VAS, ODI, and SF-36. Methods: A randomized comparative study was conducted on 120 patients with lumbar disc herniation, equally allocated to microscopic or endoscopic discectomy. Pain, disability, and quality-of-life outcomes were assessed preoperatively and during follow-up. Results: Both techniques significantly improved pain, functional disability, and quality of life. Endoscopic discectomy showed superior early postoperative outcomes, while long-term results were comparable between groups. Conclusion: Both open microscopic discectomy and endoscopic lumbar discectomy are effective surgical procedures for the management of lumbar disc herniation, providing significant improvement in pain, functional disability, and quality of life.
