A meta-analysis was performed to compare the efficacy and safety of unilateral biportal endoscopic discectomy (UBED) with conventional percutaneous endoscopic lumbar discectomy (PELD) for lumbar disc herniation (LDH). The results showed that UBED had longer surgery time and hospital stay compared to PELD, but similar efficacy in relieving pain and improving functional ability. UBED may be associated with a lower LDH recurrence, while the incidence of perioperative complications was not different.
-BACKGROUND: Unilateral biportal endoscopic dis-cectomy (UBED) is a novel and minimally invasive surgery for lumbar disc herniation (LDH). However, efficacy and safety of UBED compared to the conventional percutaneous endoscopic lumbar discectomy (PELD) remains to be determined. A meta-analysis was performed in this study to compare between UBED and PELD for LDH. -METHODS: Relevant cohort studies were found by searching Medline, Web of Science, Embase, Wanfang, and CNKI from database inception to October 13, 2022. Results were pooled using a random-effects model incorporating heterogeneity.-RESULTS: In this meta-analysis, 12 studies involving 1175 patients with LDH were included. Pooled results showed that compared with PELD, UBED was associated with a longer surgery time (mean difference [MD] 17.62 min, P < 0.001) and hospital stay (MD 1.40 day, P = 0.04). However, UBED and PELD showed comparative efficacies in improving the Visual Analogue Scale of leg and back, and Oswestry Disability Index, scores. The incidence of perioperative complications was not significantly different between the 2 procedures (risk ratio [RR] 1.62, P = 0.25), while UBED was associated with a lower LDH recurrence during follow-up (RR 0.29, P = 0.03).-CONCLUSIONS: Although UBED is associated with longer surgery time and hospital stay, it shows similar efficacy to PELD in relieving pain and improving functional ability in patients with LDH. In addition, limited evidence suggests that UBED may be associated with a lower LDH recurrence as compared to PELD, while the incidence of perioperative complications is not different. These findings support UBED as a treatment for patients with LDH.
