Comparison of biportal versus uniportal endoscopic decompression for the treatment of lumbar degenerative disease: a systematic review and meta‑analysis

Key Points

The research aims to compare the postoperative outcomes of biportal versus uniportal endoscopic surgeries for lumbar degenerative disease.
Conducted a systematic review
Performed meta-analysis of existing studies
Compared outcomes including operative time and recovery
Assessed improvement in Oswestry Disability Index (ODI)
Postoperative outcomes are comparable between both techniques
Biportal surgery showed a modest but non-significant benefit in ODI improvement
Uniportal surgery was more efficient in terms of reduced operative time and quicker recovery

Abstract

Both uniportal and biportal endoscopic spine surgeries yield comparable postoperative outcomes in LDD. Although biportal surgery showed a modest advantage in ODI improvement, it did not reach the minimal clinically important difference. Uniportal surgery demonstrated greater efficiency in terms of operative time and recovery, particularly for discectomy procedures.
