BackgroundThe aim of this study was to evaluate whether there is a superior clinical effect of unilateral biportal endoscopy compared with microscopic decompression in the treatment of lumbar spinal stenosis.MethodsWe searched CNKI, WANFANG, CQVIP, CBM, PubMed, and Web of Science up to January 2022, and selected studies that met our inclusion criteria.ResultsThe results of this meta-analysis indicated that unilateral biportal endoscopy was demonstrated to be more beneficial for patients compared with microscopic decompression for the following outcomes: Operation time [standardized mean difference (SMD) = -0.943, 95% confidence interval (CI) (-1.856, -0.031), P = .043], hospital stays [SMD = -2.652, 95% CI (-4.390, -0.914), P = .003], EuroQol 5-Dimension questionnaire [SMD = 0.354, 95% CI (0.070, 0.638), P = .014], back pain visual analogue score [SMD = -0.506, 95% CI (-0.861, -0.151), P = .005], leg pain visual analogue score [SMD = -0.241, 95% CI (-0.371, -.0112), P = .000], the C-reactive protein level [SMD = -1.492,95% CI (-2.432, -0.552), P = .002]. Other outcomes demonstrated no significant differences between the 2 groups.ConclusionFor patients with lumbar spinal stenosis, unilateral biportal endoscopy was found to be more superior than microscopic decompression in terms of operation time, hospital stays, EuroQol 5-Dimension questionnaire, back visual analogue score, leg visual analogue score and the C-reactive protein level. There was no significant difference between the 2 groups in other outcome indicators.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
