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

Key Points

This analysis aims to compare the effectiveness of endoscopic and microscopic unilateral laminotomy for bilateral decompression in lumbar spinal stenosis.
Conducted a meta-analysis of existing studies comparing Endo-ULBD and Micro-ULBD.
Evaluated long-term back pain relief, early functional recovery, and symptom relief for radicular leg pain.
Assessed hospital stay duration, blood loss, and complication rates associated with both techniques.
Endo-ULBD shows superior long-term relief from back pain compared to Micro-ULBD.
Early functional recovery is significantly better in Endo-ULBD participants.
Both techniques provide similar relief for radicular leg pain based on VAS leg scores.
Endo-ULBD is associated with shorter hospital stays, lower blood loss, and fewer complications.

Abstract

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.
