Efficacy and Safety of Unilateral Biportal Endoscopy Compared with Percutaneous Endoscopic Interlaminar Discectomy for the Treatment of Lumbar Lateral Recess Stenosis: A Minimum 6-month Follow-up
This retrospective study of 156 patients with lumbar lateral recess stenosis demonstrates that while unilateral biportal endoscopy (UBE) and percutaneous endoscopic interlaminar discectomy (PEID) share similar perioperative profiles, UBE provides superior long-term leg pain relief, functional recovery, and patient satisfaction at 6-month follow-up with no recurrence cases compared to PEID.
