Abstract：
UNASSIGNED: Laminectomy has long been a \"gold standard\" to treat symptomatic lumbar spinal stenosis (LSS). Minimal invasive spine surgery (MISS) is widely developed to overcome the limitations of conventional laminectomy to achieve a better outcome with minimal complications. Full endoscopic percutaneous stenoscopic lumbar decompression (FE-PSLD) is the newest MISS technique for spinal canal decompression. We aimed to evaluate and analyze the significance of FE-PSLD in reducing pain and its association with age, duration of symptoms, stenosis level, and operative time (OT).
UNASSIGNED: A longitudinal cross-sectional study was conducted on 606 LSS patients who underwent FE-PSLD and enrolled from 2020 to 2022. Three-month evaluation of the Visual Analog Scale (VAS) and the modified MacNab criteria were assessed. The significance of changes was analyzed using the Wilcoxon signed-ranks test. Spearman\'s correlation test was performed to evaluate the significant correlation of several variables (pre-PSLD-VAS, age, symptoms duration, OT, and level of LSS) to post-PSLD-VAS, and multiple regression analysis was conducted.
UNASSIGNED: The reduction of VAS was statistically significant (P ≤ 0.005) with an average pre-PSLD-VAS of 6.75 ± 0.63 and post-PSLD-VAS of 2.24 ± 1.04. Pre-PSLD-VAS, age, and stenosis level have a statistically significant correlation with post-PSLD-VAS, while the duration of the symptoms and OT have an insignificant correlation. Multiple regression showed the effect of pre-PSLD-VAS (β =0.4033, P = 0.000) and stenosis level (β =0.0951, P = 0.021) are statistically significant with a positive coefficient.
UNASSIGNED: FE-PSLD is an efficacious strategy with favorable outcomes for managing LSS, shown by a significant reduction of pain level with a relatively short follow-up time after the procedure. Preoperative pain level, age, and stenosis level are significantly correlated with postoperative pain level. Based on this experimental study, PSLD can be considered a good strategy for treating lumbar canal stenosis in all age groups and all LSS levels.

摘要：
■椎板切除术长期以来一直是治疗症状性腰椎管狭窄症（LSS）的“金标准”。微创脊柱手术（MISS）被广泛开发，以克服传统椎板切除术的局限性，以最小的并发症获得更好的结果。全内镜下经皮狭窄腰椎减压术（FE-PSLD）是最新的MISS椎管减压技术。我们旨在评估和分析FE-PSLD在减轻疼痛中的意义及其与年龄的关系。症状持续时间，狭窄程度,和手术时间（OT）。
■对606名接受FE-PSLD并从2020年至2022年招募的LSS患者进行了纵向横断面研究。评估了视觉模拟量表（VAS）和改良的MacNab标准的三个月评估。使用Wilcoxon符号秩检验分析变化的显著性。进行了Spearman相关性检验，以评估几个变量(Pre-PSLD-VAS，年龄,症状持续时间,OT,和LSS水平)到PSLD-VAS后，进行多元回归分析。
■VAS的降低具有统计学意义（P≤0.005），PSLD-VAS前平均为6.75±0.63，PSLD-VAS后平均为2.24±1.04。Pre-PSLD-VAS,年龄,狭窄程度与PSLD-VAS后有统计学意义的相关性，而症状的持续时间与OT之间无明显相关性。多元回归分析显示Pre-PSLD-VAS(β=0.4033,P=0.000)和狭窄程度(β=0.0951,P=0.021)的影响有统计学意义,具有正系数。
■FE-PSLD是一种有效的策略，对管理LSS具有良好的效果，在手术后相对较短的随访时间内，疼痛程度显着降低。术前疼痛程度,年龄,狭窄程度与术后疼痛程度显著相关。基于本实验研究,PSLD可以被认为是治疗所有年龄段和所有LSS水平的腰椎管狭窄症的良好策略。
