A meta-analysis of clinical efficacy and safety of unilateral laminotomy for bilateral decompression between unilateral biportal endoscopy and uniportal endoscopy in treatment of lumbar spinal stenosis
Objective To compare the clinical efficacy and safety of unilateral laminotomy for bilateral decompression be-tween unilateral biportal endoscopy(UBE-ULBD)and uniportal endoscopy(PE-ULBD)in the treatment of lumbar spinal steno-sis by Meta-analysis.Methods PubMed,Web of Science,EMbase,CNKI,Wanfang Database and VIP database were searched for studies comparing the safety and efficacy of UBE-ULBD surgery and PE-ULBD surgery for lumbar spinal stenosis.Review Manager 5.3 software was used for Meta-analysis.The operation time,intraoperative blood loss,postoperative complica-tions,postoperative lower limb pain VAS score,postoperative ODI index and postoperative dural expansion area were compared between the UBE-ULBD group and the PE-ULBD group.Results A total of 6 articles were included,including 5 cohort stud-ies(high quality)and 1 randomized controlled trial study(low quality).A total of 329 patients were enrolled,including 170 pa-tients in the UBE-ULBD group and 159 patients in the PE-ULBD group.There was no significant difference in operation time,intraoperative blood loss,VAS score of lower limb pain after operation,incidence of postoperative complications,and ODI index at 12 months after operation between the two groups(P＞0.05).The ODI index at 3 months after operation of UBE-ULBD group was lower than that of PE-UBLD group,and the expansion area of dura after operation of PE-ULBD group was larger than that of PE-ULBD group(P＜0.05).Conclusion The efficacy of UBE-ULBD is similar to PE-ULBD in the treatment of lumbar spi-nal stenosis.UBE-ULBD is more suitable for the treatment of bilateral recess or central spinal stenosis.UBE-ULBD can pro-vide a larger intraoperative field of view,thus achieving better decompression effect and high safety.
