Abstract：Objective:To investigate the therapeutic effects of unilateral biportal endoscopy(UBE)and microscopic bilateral decompression(MBD)on degenerative lumbar spinal stenosis(DLSS).Method:Eighty patients with DLSS who were treated in the Department of Spinal,Hands and Ankles Surgery of the Second Hospital of Longyan City from January 2020 to December 2022 were selected and randomly divided into UBE group(n=40,UBE was used during operation)and MBD group(n=40,MBD was used during operation)by the envelope method.Operation related indexes(operation time,postoperative off-bed activity and length of hospital stay)in the two groups were observed.The visual analogue scale(VAS)scores for the waist and lower limbs,Oswestry disability index(ODI),and clinical efficacy evaluated based on modified MacNab criteria were evaluated.Postoperative complications were recorded.Result:Operation time,postoperative ambulation time,hospital stay of UBE group were shorter than those of MBD group,and postoperative complication rate of UBE group was significantly lower than that of MBD group,the difference were statistically significant(P＜0.05).At 1 month and 3 months after operation,visual analogue scale(VAS)scores of the waist and lower limbs and ODI scores of both groups were significantly lower than those before operation,UBE group had significantly better scores than MBD group,and the excellent and good rate in UBE group was significantly higher than that in MBD group,the difference were statistically significant(P＜0.05).Conclusion:Compared to MBD,UBE used in operation for DLSS can achieve central spinal canal nerve,reduce soft tissue and bone structure damage,greatly reduce the risk of operation,efficiently relieve lumbar and lower limb pain,and promote lumbar function recovery.
