Abstract Objective To explore the recent efficacy of percutaneous large channel spinal endoscopy in the treatment of single segment lumbar spinal stenosis in the elderly.Methods From January 2020 to January 2021，24 elderly patients with single level degenerative lumbar spinal stenosis were treated by percutaneous large channel spinal endoscopy in our department，including 13 males and 11 females.The average age was 60~84 years (72.6±4.3).The section of responsible included 4 cases at L_3～4segment，12 cases at L_4～5 segment，and 8 cases at L₅S₁ segment.Lumbar spinal stenosis patients included 6 cases of central type，12 cases of lateral recess type，6 cases of central type combined with lateral recess type.Visual analogue scale (VAS) and Oswestry disability index (ODI) were used to evaluate the patients before and after surgery，and MacNab was improved to evaluate the clinical efficacy of patients.Results The 24 patients in this group successfully completed the operation.The operation time was 55~86 min (65.3±10.4) min.Tthe intraoperative fluoroscopy was 3~5 times (3.2±0.2) times.The length of the surgical incision was about 10 mm，and the hospital stay was 3~7 days (4.1±0.3) days.Dural sac tear occurred in 1 patient during operation.One patient had pain and allergy in the affected limb.There were no obvious sequelae after symptomatic treatment.The patients were followed up for 12 to 24 months (16.3±2.1) months.The VAS score and ODI score of lumbar and leg pain after surgery were statistically different from those before surgery (P＜0.05).There was significant difference between each time point after operation (P＜0.05).At 12 months after operation，the modified MacNab evaluation showed that the curative effect was excellent in 18 cases，good in 3 cases，and fair in 3 cases，with an excellent and good rate of 87.5%.Conclusion Percutaneous large channel spinal endoscopy for the treatment of elderly single segment lumbar spinal stenosis has the advantages of less trauma，less bleeding，short hospital stay，quick postoperative recovery，and good short-term effect.
