Comparing the efficacy and complications of unilateral biportal endoscopic fusion versus minimally invasive fusion for lumbar degenerative diseases: a systematic review and mate-analysis

摘要

Abstract Background Unilateral biportal endoscopic (UBE) has been gradually applied in clinical practice. UBE has two channels, with good visual field and operating space, and has achieved good results in the treatment of lumbar spine diseases. Some scholars combine UBE with vertebral body fusion to replace traditional open fusion surgery and minimally invasive fusion surgery. The efficacy of biportal endoscopic transforaminal lumbar interbody fusion (BE-TLIF) is still controversial. In this systematic review and meta-analysis, BE-TLIF and minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) are compared in the efficacy and complications?of lumbar degenerative diseases.Methods PubMed, Cochrane Library, Web of Science and China National Knowledge Infrastructure (CNKI) were used to search literatures related to BE-TLIF before January 2023, to identify relevant studies, and systematically review all literatures. Evaluation indicators mainly include operation time, hospital stay, estimated blood loss, visual analog scale (VAS), Oswestry Disability Index (ODI), and Macnab.Results A total of 9 studies were included in this study; a total of 637 patients were collected, and 710 vertebral bodies were treated. Nine studies showed that there was no significant difference in VAS score, ODI, fusion rate, and complication rate between BE-TLIF and MI-TLIF at the final follow-up after surgery.Conclusion This study suggests that BE-TLIF is a safe and effective surgical approach. BE-TLIF surgery has similar good efficacy to MI-TLIF in the treatment of lumbar degenerative diseases. And compared with MI-TLIF, it has the advantages of early postoperative relief of low-back pain, shorter hospital stay, and faster functional recovery. However, high-quality prospective studies are needed to validate this conclusion.Graphical abstract
