Treatment modalities have been advancing, and the application of Enhanced Recovery After Surgery (ERAS) principles provides a new approach to postoperative recovery in patients. This study aims to investigate the clinical application effects of ERAS principles in single-level lumbar spinal stenosis surgery. Methods: This study included 64 patients who underwent lumbar fusion surgery in the Spinal Surgery Department of Baise People’s Hospital from July 2022 to July 2024. These patients were divided into an experimental group (ERAS group, 33 cases) and a control group (conventional group, 31 cases) based on perioperative care, receiving ERAS principles and traditional treatment, respectively. A comparison was made between the two groups in terms of gender, age, BMI, intraoperative blood loss, postoperative length of hospital stay, postoperative complications, hospital costs, VAS scores (preoperative/postoperative day 3), and ODI scores (preoperative/postoperative day 3). Results: There were no significant differences in gender, age, and BMI between the ERAS group and the conventional group (gender: χ2 = 0.5008, P = 0.4792;age: 54.55 ± 8.51 years vs. 57.39 ± 8.16 years, P = 0.0892;BMI: 25.11 ± 2.70 vs. 24.77 ± 2.75, P = 0.3098). However, during surgery, patients in the ERAS group had significantly less blood loss than those in the conventional group (197.58 ± 195.51ml vs. 438.71 ± 349.22 ml, P = 0.0006), and the postoperative length of hospital stay was significantly shorter (7.00 ± 2.24 days vs. 11.55 ± 5.23 days, P = 0.0000). On postoperative day 3, VAS scores were significantly better in the ERAS group compared to the conventional group (3.70 ± 0.88 vs. 4.32 ± 0.87, P = 0.0031), and the ODI scores showed significant improvement as well (46.00 ± 3.04 vs. 48.00 ± 3.39, P = 0.0078). Although there were no significant differences in postoperative complications and hospital costs (complications: 3 cases vs. 0 cases, P = 0.2154;hospital costs: 63524.29 ± 17891.80 RMB vs. 58733.84 ± 13280.82 RMB, P = 0.1154), ERAS demonstrated better postoperative recovery outcomes in single-level lumbar spinal stenosis surgery. Conclusion: The study results support the implementation of ERAS principles in single-level lumbar spinal stenosis surgery to promote rapid recovery, reduce healthcare resource consumption, and improve overall patient satisfaction.展开更多

However, long-term outcomes of Dynesys for lumbar spinal stenosis are rarely reported. The aim of this study was to analyze the long-term clinical and radiologic outcomes for patients with lumbar spinal stenosis treated with Dynesys stabilization. Methods： Thirty-eight patients with lumbar spinal stenosis were treated with Dynesys stabilization from July 2008 to March 2010. The minimal duration of follow-up was 72 months. The patients were divided into stenosis and spondylolisthesis groups according to degenerative spondylolisthesis. Clinical outcomes were evaluated using the Oswestry Disability Index （ODI） and visual analog scale （VAS）. Radiographic evaluations included range of motion （ROM） and the disc heights of stabilized segments and the upper adjacent segments. We also evaluated the occurrence of radiographic and symptomatic adjacent segment degeneration （ASD）. Results： There were 23 patients in stenosis group and 15 patients in spondylolisthesis group. The ODl scores were significantly improved at the final follow-up evaluation, as compared to the baseline values （ 16.1± 5.7 vs. 57.2 ± 14.2, t = 61.4 l, P 〈 0.01 ）. The VA S scores for back and leg pain were significantly improved from 4.82 ±0.89 and 4.04 ± 0.82 preoperatively to 0.93± 0.61 and 0.54 ± 0.51 postoperatively （t = 6.59, P 〈 0.01, and t = 5.91, P 〈 0.01, respectively）. There were no differences between the two groups with respect to VAS and ODI scores. The ROM of stabilized segments decreased significantly from 7.8°± 2.4° to 4.5° ± 1.5° （t = 7.18, P 〈 0.05）, while the upper adjacent segments increased significantly from 8.3° ± 2.4° to 10.4° ± 2.4° （t = 2.87, P = 0.01）. The change in disc height of stabilized segments was not significant （11.9 ±2.1 preoperatively vs. 12.5 ± 1.5 postoperatively, t = 1.43, P = 0.15）, whereas the decrease in disc height of the upper adjacent segments was significant （12.5 ±2.0 preopcratively vs. 11.0 ± 1.7 postoperatively, t = 2.94, P = 0.01 ）. The occurrence of radiographic and symptomatic ASD was 16% （6/38） and 3% （1/38）, respectively. Conclusions： Decompression and Dynesys stabilization for lumbar stenosis with or without spondylolisthesis showed good long-term clinical and radiographic results. Lumbar stenosis with or without Grade I spondylolisthesis, particularly in patients 〈60 years of age with mild-to-moderate lumbar disc degeneration, would be one of the main indications for the Dynesys system.展开更多
