Abstract:
Objectives:To explore the application value of percutaneous co-axial large-channel endoscopic lumbar interbody fusion(PLE-LIF)combined with full surgical area closure technique(FSAC)in the treatment of degenerative lumbar spondylolisthesis.Methods:A retrospective analysis was conducted on 83 patients with single-segment degenerative lumbar spondylolisthesis who underwent PLE-LIF in our hospital from January 2020 to January 2023.Among the patients,46 received FSAC treatment during operation(FSAC group),and 37 patients did not receive FSAC treatment(N-FSAC group).Both groups of patients were comparable in gen-eral information such as gender,age,course of illness,and length of hospital stay(P＞0.05).The two groups of patients were followed up for l year.The operative time and complications of the two groups of patients were recorded.Both groups of patients were followed up regularly for 1 year.The visual analogue scale(VAS)for low back pain and lower limb pain was recorded on ld before surgery,3d after surgery,at 3 months and 1 year after surgery,in addition,the Oswestry disability index(ODI)on 1d before surgery,at 3 months and 1 year after surgery was recorded.X-ray examination was performed at 3 months after operation,and Meyerding grading was used to evaluate the reduction of spondylolisthesis.CT examination was performed at 1 year after operation,and Brantigan criteria were used to evaluate the intervertebral fusion.Results:The operative time in the FSAC group was shorter than that in the N-FSAC group(118.9±10.6min vs 130.6±16.3min,P＜0.05).The VAS for low back pain and lower limb pain and ODI at each postoperative time point in the two groups were significantly lower than those before surgery(P＜0.05),and there was no statistically significant difference between the two groups at each time point(P＞0.05).Two cases of lower limb numbness occurred in the N-FSAC group,while none occurred in the FSAC group;There were 4 cases and 1 case of neuroedema pain in the N-FSAC group and FSAC group,respectively;1 case in each group respectively had cage displacement,and there was no internal fixation loosening,infection,or dural sac tear in both groups.The incidence rate of intraoperative complications in the N-FSAC group was higher than that in the FSAC group(18.9％vs 4.3％)(P＜0.05).One year after surgery,the degree of slippage in both groups of patients improved significantly compared to the conditions before operation(P＜0.05),and there was no significant difference between the two groups(P＞0.05);Intervertebral fusion occurred in 42 cases in the FSAC group,and 34 cases in the N-FSAC group,and no statistically significant difference was there in the fusion rate(91.3％vs 91.9％)and intervertebral fusion grading between the two groups(P＜0.05).Conclusions:PEL-LIF combined with FSAC can shorten the operative time and improve safety in treating single-segment degenerative lumbar spondylolisthesis.
