Effect of transforaminal endoscopic discectomy extent on postoperative neurological recovery in lumbar disc herniation: a retrospective cohort study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: To investigate whether limited discectomy versus aggressive disc removal influences postoperative neurological recovery in lumbar disc herniation patients undergoing transforaminal endoscopic discectomy. Methods: This retrospective cohort study analyzed 288 patients undergoing percutaneous endoscopic lumbar discectomy (PELD) at our institution between January 2022 and January 2025. Patients were stratified by surgical approach based on established criteria: Aggressive Discectomy Group (comprehensive removal of herniated disc and extensive nucleus pulposus extraction, Results: Both groups demonstrated significant improvement in neurological function from baseline to 6 months postoperatively. No significant differences emerged between groups regarding sensory function recovery (normal/reduced sensation at 6 months: 126/9 vs. 149/4, Conclusion: Limited discectomy achieved equivalent neurological recovery outcomes compared to aggressive disc removal while requiring significantly less operative time. These findings support adopting less extensive surgical approaches when adequate neural decompression can be accomplished, potentially reducing surgical trauma while maintaining therapeutic efficacy. While these 6-month findings support limited discectomy for early recovery, longer follow-up studies are needed to assess medium to long-term outcomes including recurrence rates and degenerative changes.
