Abstract：Objective To compare the differences of curative effects of unilateral biportal endoscopy(UBE)and percutaneous endoscopic lumbar discectomy(PELD)in the treatment of degenerative lumbar spinal stenosis(DLSS).Methods Clinical data of 74 DLSS patients treated from October 2021 to June 2022 in Qinzhou First People's Hospital were retrospectively analyzed.According to different procedures,patients were divided into UBE group(performing UBE surgery,n=38)and PELD group(performing PELD surgery,n=36).Operative time and perioperative complications were recorded,visual analogue scale(VAS)score and Oswestry disability index(ODI)before and after the operation were evaluated,dural sac cross-sectional area(DSCA)at 1 month after surgery and surgical outcome evaluated by modified MacNab criteria at 12 months postoperatively were compared between the two groups.Results The operation was successfully completed in both groups.Compared with the PELD group,the UBE group had shorter operation time(P<0.05).Incidence of perioperative complications as well as excellent and good rate of surgical outcome at 12 months postoperatively were similar in two groups(P>0.05).VAS score at 1 d,1 and 12 months postoperatively,as well as ODI at 1 and 12 months after the surgery were all improved compared with preoperative ones(P<0.05),while there was no statistical difference between the two groups at the same timepoint(P>0.05).At 1 month after surgery,DSCA of patients in UBE group were larger than those in PELD group,there was statistical difference between two groups(P<0.05).Conclusions UBE and PELD are both effective surgical methods for DLSS.In UBE group,the operation time is shorter and the increase of postoperative DSCA is larger,which could provide guidance for surgical selection.
