Uniportal Endoscopic Versus Microscopic Unilateral Laminotomy for Bilateral Decompression in the Treatment of Lumbar Spinal Stenosis: A Meta-Analysis

This meta-analysis reveals that Endo-ULBD demonstrates superior long-term back pain relief compared to Micro-ULBD, while also offering significant early functional recovery advantages. Critically, both techniques were found to be equally effective in providing symptomatic relief for radicular leg pain, as measured by VAS leg scores. Although both procedures ultimately yield comparable functional outcomes, Endo-ULBD presents additional benefits, including reduced hospital stay duration, decreased blood loss, and lower complication rates. These findings underscore the distinct advantages of Endo-ULBD in LSS surgical interventions.
