- Abstract: Objective To evaluate the short-term clinical efficacy of unilateral biportal endoscopic(UBE)technique in the treatment of adjacent segment disease after lumbar interbody fusion.Methods The clinical data of 21 patients with adjacent segment disease after lumbar interbody fusion who treated with UBE technique and followed up for more than 3 months in our hospital from March 2020 to January 2023 were retrospectively analyzed.The operation time,decrease value of hemoglobin 1 day before and after operation,drainage volume of the operation area,time of bed rest and complications were recorded.The Japanese Orthopaedic Association(JOA)score was used to evaluate lumbar function 1 day before operation,3 days and 3 months after operation to determine the improvement.The visual analogue scale(VAS)score was used to evaluate the pain 1 day before operation,3 days and 3 months after operation.Results The operation time was 60～175 minutes,with an average of(95.38±18.64)minutes;the decrease value of hemoglobin was 2～6 g/L,with an average of(1.42±0.18)g/L;the time of bed rest was 27～88 hours,with an average of(36.42±15.33)hours;the drainage volume of the operation area was 50～315 mL,with an average of(85.56±15.65)mL;and one case of dural tear occurred during the operation,who was converted to open surgery for repairing dural sac.There was statistically significant difference in VAS score before operation compared with that 3 days and 3 months after operation(P<0.05).There was statistically significant difference in the JOA score before operation compared with that 3 days and 3 months after surgery(P<0.05).Conclusion UBE technique is effective in the treatment of adjacent segment disease after lumbar interbody fusion,with the advantages of small trauma,little bleeding and short time of bed rest.However,patients with the serious adjacent segment degeneration and severe spinal stenosis may have dural tear during operation.Once it occurs,active repair should be performed to avoid cauda equina herniation and necrosis,or switch to open surgery,if necessary.
