Abstract:

Objective　To investigate the short-term clinical efficacy of unilateral biportal endoscopic (UBE) nerve root release surgery in the treatment of lumbar spinal stenosis. Methods　A total of 18 patients with lumbar spinal stenosis who were admitted to the First Affiliated Hospital of Wannan Medical College from May to November 2023 were included. Among them, there were 9 males and 9 females, with ages ranging from 36 to 76 (52.78±8.98) years old, and the affected segments were L3/4 in 1 case, L4/5 in 9 cases, and L5/S1 in 8 cases. All the patients underwent UBE nerve root release surgery. The Visual Analogue Scale (VAS) scores of low back pain and leg pain and Oswestry Disability Index (ODI) before surgery, on the first day after surgery, and at the last follow-up were compared; the clinical efficacy at the last follow-up was evaluated using the MacNab scoring system. Statistical analysis was conducted using analysis of variance and Dunnett's T3 multiple comparison method. Results　All 18 patients successfully completed the surgery without any complication during or after surgery. The surgical duration ranged from 35 to 130 (75.17±24.21) minutes, the postoperative hospital stay was 1 to 8 (2.22±1.59) days, and the follow-up period was 13 to 18 (16.00±1.81) months. On the first day after surgery, there was no statistically significant difference in the VAS score of lower back pain compared to the preoperative score (P>0.05); the VAS score of lower back pain at the last follow-up was lower than that before surgery and on the first day after surgery, with statistically significant differences (both P<0.05). The VAS scores of leg pain and ODIs on the first day after surgery and at the last follow-up were all improved compared to those before surgery (all P<0.05). At the last follow-up, the clinical efficacy was evaluated using the MacNab score: excellent in 15 cases, good in 1 case, and fair in 2 cases, with an excellent and good rate of 88.89% (16/18). Conclusion　UBE nerve root release surgery for lumbar spinal stenosis can achieve satisfactory clinical efficacy, providing another minimally invasive surgical option for lumbar spinal stenosis, and is conducive to the patients' rapid rehabilitation.
