- Abstract: Objective To analyze the efficacy and safety of unilateral laminectomy and bilateral decompression under unilateral biportal endoscopy(UBE)and microendoscope(MED)in lumbar spinal stenosis.Methods 80 patients with lumbar spinal stenosis from January 2021 to December 2022 were selected and divided into two groups by numerical table method,the control group and the study group,and the number of cases was 40.The grouping method was random number table method.The control group was treated with unilateral laminectomy and bilateral decompression under MED,while the study group was treated with unilateral laminectomy and bilateral decompression under UBE.Operation time,intraoperative blood loss,Oswestry disability index(ODI)and visual analogue scale(VAS)of lumbago and leg pain were obtained before surgery,1,3 months after surgery and at the last follow-up,efficacy and complications were compared between the two groups.Result There were no significant differences in operative time and blood loss between the study group and the control group(P>0.05).1,3 months after surgery and at the last follow-up,ODI in both groups were lower than those before surgery(P<0.05),but there was no difference between the study group and the control group(P>0.05).The VAS of lumbago and leg pain in both groups were lower than those before surgery(P<0.05),at 1,3 months after surgery and the last follow-up,and the study group was significantly lower than the control group(P<0.05).The excellent and good rate of clinical treatment in the study group was 97.50%,and there was no difference compared with 92.50%in the control group(P>0.05).The complication rate of the study group was 2.50%,significantly lower than that of the control group(15.00%)(P<0.05).Conclusion Unilateral laminectomy and bilateral decompression under the UBE and MED have similar efficacy in the treatment of lumbar spinal stenosis,both of which can effectively promote functional recovery,but UBE can reduce pain more effectively and has fewer postoperative complications.
