Implication

Meta-analysis reveals similar outcomes for UBED and PELD in lumbar disc herniation, suggesting potential benefits of PELD.

Key Points

  • This research aims to compare the outcomes of unilateral biportal endoscopic discectomy and percutaneous endoscopic lumbar discectomy for treating lumbar disc herniation.
  • Systematic review of studies from PubMed, Embase, and Cochrane databases until July 2025.
  • Included nine observational studies involving 845 patients (387 UBED and 458 PELD).
  • Outcomes assessed included change in VAS Leg, VAS Back, ODI, operating time, and intraoperative blood loss.
  • Both procedures showed comparable improvement in leg pain and back pain at 6 months.
  • PELD had shorter operative time, less blood loss, and shorter hospital stay.
  • Complication rates were similar between UBED and PELD.
