Abstract: 【Objective】 Compare the early outcome and safety of endoscopy-unilateral laminectomy for bilateral decompression （Endo-ULBD） and posterior lumbar interbody fusion （PLIF） in the treatment of multi-segment lumbar central spinal stenosis. 【Methods】 We retrospectively analyzed 68 patients with multi-segment central lumbar spinal stenosis treated between October 2019 and October 2020 in the Department of Spine Surgery， Affiliated Hospital of Qingdao University. Of them 33 patients were treated with Endo-ULBD and 35 ones were treated with PLIF. We compared the operation time， times of intraoperative fluoroscopy， estimated intraoperative blood loss， incision length， postoperative time to get out of bed， postoperative hospital duration， complications， visual analogue scale （VAS）， Oswestry dysfunction index （ODI） score before and 1 day， 1 month， and 3 months after operation， Japanese Orthopedic Association Assessment Treatment Score （JOA）， and modified MacNab score 3 months after operation between the two groups of patients. 【Results】 Compared with PLIF group， Endo-ULBD group had significantly shorter operation time， smaller incision length， less intraoperative blood loss， shorter postoperative bed time and postoperative hospital stay， and fewer surgical complications （all P<0.05）. There was significantly more intraoperative fluoroscopy in Endo-ULBD group than in PLIF group （P<0.05）. The VAS， ODI and JOA scores of the two groups were significantly improved after treatment （P<0.05）. There was no statistical difference in VAS of leg pain between the two groups after treatment （P>0.05）. However， after treatment Endo-ULBD group outperformed PLIF group in lower back pain VAS， ODI， JOA and the 3-month follow-up excellent and good rates （P<0.05）. 【Conclusion】 For patients with multi-segment central lumbar spinal stenosis， Endo-ULBD treatment can achieve better early clinical outcome than PLIF surgery， with less bleeding， shorter operation time， faster postoperative recovery， and fewer complications.
