Comparison of effects of unilateral biportal endoscopy and transforaminal endoscopic discectomy in treatment of patients with lumbar spinal stenosis
Objective:To compare effects of unilateral biportal endoscopy(UBE)and percutaneous transforaminal endoscopic discectomy(PTED)in treatment of patients with lumbar spinal stenosis(LSS).Methods:The clinical data of 64 patients with LSS admitted to the hospital from May 2019 to February 2023 were retrospectively analyzed.According to different surgical methods,they were divided into observation group(n=32)and control group(n=32).The observation group was treated with UBE,while the control group was treated with PTED.The excellent and good rate of treatment,the levels of operation-related indicators,the scores of lumbar function[Oswestry disability index(ODI)],the pain degree[visual analogue scale(VAS)]before and after the surgery,and the incidence of complications were compared between the two groups.Results:There was no significant difference in the excellent and good rate between the two groups(P>0.05).The intraoperative blood loss in the observation group was less than that in the control group;the first anal exhaust time,the operation time,the first ambulation time and the hospitalization time were shorter than those in the control group;and the differences were statistically significant(P<0.05).At 1 and 3 months after the surgery,the ODI scores of both groups were lower than those before surgery,but there were no statistically significant differences between the two groups(P>0.05).Further,1 and 3 days after the surgery,the VAS scores of the two groups were lower than those before the surgery,those in the observation group were lower than those in the control group,and the differences were statistically significant(P<0.05).There was no statistically significant difference in the incidence of postoperative complications between the two groups(P>0.05).Conclusions:The overall effects of UBE and PTED in the treatment of the LSS patients are similar.However,UBE treatment can reduce the VAS scores,and it is superior to the PTED treatment.
