Abstract:
Objective To compare the therapeutic effects of two different surgical methods for lumbar spinal stenosis: open and channel. Methods The 95 patients with lumbar spinal stenosis admitted to our hospital from January 2021 to June 2022 divided into open group (46 cases) and access group (49 cases) according to the surgical methods. The open group was treated with traditional laminectomy, decompression and internal fixation, and the channel group was treated with fixed channel technology. Compare the two groups of patients who completed 6 months of follow-up. Operation indexes and postoperative complications of the two groups; changes of pain mediator and stress response index in patients before and 3 days after operation; low back pain and leg pain and lumbar function changes before, 1 month and 6 months after operation. Results The channel group amount of intraoperative bleeding of patients with lumbar spinal stenosis less than open group, the operation time longer than open group, and the hospitalization time shorter than open group (P<0.05). The channel group postoperative complications of patients with lumbar spinal stenosis less than open group (P<0.05). The two groups 3 days after operation levels of Cor and NE in patients with lumbar spinal stenosis higher than before operation (P<0.05); the channel group level of Cor and NE in patients with lumbar spinal stenosis lower than open group (P<0.05). The two groups 3 days after operation levels of NPY and SP in patients with lumbar spinal stenosis higher than before operation, while β- EP level lower than before operation (P<0.05); the channel group levels of NPY and SP in the patients with lumbar spinal stenosis lower than open group, while level of β-EP higher than open group (P<0.05). The two groups 1 month and 6 months after operation VAS scores of low back pain and leg pain in patients with lumbar spinal stenosis lower than before operation (P<0.05); the channel group VAS scores of low back pain and leg pain in patients with lumbar spinal stenosis lower than open group (P<0.05). The two groups 1 month and 6 months after operation ODI of low back pain and leg pain in patients with lumbar spinal stenosis lower than before operation (P<0.05); the channel group ODI of low back pain and leg pain in patients with lumbar spinal stenosis lower than open group (P<0.05). Conclusion Compared with open surgery, fixed channel technology for lumbar spinal stenosis has a better effect, fewer complications, and can significantly inhibit the release of pain mediators, have a small impact on stress response, significantly reduce pain and significantly improve lumbar function.
