Key Points

This report aims to highlight the unique challenges and outcomes of endoscopic discectomy for high-level lumbar disc herniation.
Utilized unilateral biportal endoscopic techniques.
Examined endoscopic findings at L2-3 and L1-2 levels.
Identified the presence of nucleus pulposus in dorsal epidural space.
No nucleus pulposus found at the L2-3 level.
