Early clinical efficacy of unilateral biportal endoscopic unilateral laminotomy for bilateral decompression in the treatment of two-level lumbar spinal stenosis
Objective To analyze the early efficacy of unilateral biportal endoscopic(UBE)unilateral laminotomy for bilateral de-compression(ULBD)in the treatment of two-level lumbar spinal stenosis(LSS).Methods The clinical data of patients with two-lev-el lumbar spinal stenosis who underwent UBE lower spinal canal decompression in our hospital from October 1,2019 to November 31,2021 were followed up for more than 1 year were retrospectively analyzed.A total of 25 patients with two-level lumbar spinal stenosis were included,the surgical time,postoperative hospital stay,and postoperative complications of all patients were recorded,and their clinical efficacy were observed.Results The VAS scores of patients with low back pain and leg pain on the 2nd day,1 month,3 months and 1 year after surgery were significantly lower than those before surgery(P＜0.05);ODI scores at 1 year after surgery were significantly lower than those before surgery(P＜0.05)and JOA scores were significantly higher than those before surgery(P＜0.05).The mean operation time was 110.67±13.73 minutes,and the postoperative hospitalization time was 4.52±0.83 days.Ac-cording to the modified MacNab criteria,15(60％)cases were excellent,8(32％)cases were good,and 2 cases were fair,with an excellent and good rate of 92％.The percentage of facet joint preservation was(83.2±9.1)％on the approach side and(93.9±5.2)％on the contralateral side.No lumbar instability was found on dynamic position radiographs in all patients at the final follow-up.Postoperative dural tear occurred in 1 case,the dural tear was not repaired during the operation,and conservative treatment such as flu-id rehydration was given,and no cerebrospinal fluid leakage occurred.Conclusion The UBE decompression technique for LSS is a safe and effective MI technique.Soft tissue destruction and the facet joint destruction can be minimized.It is therefore possible to avoid spinal fusion as well as to preserve the segmental mobility and stability.
