Clinical analysis of percutaneous transforaminal endoscopic surgery for elderly patients with lumbar spinal stenosis

Objective To determine the effect of percutaneous transforaminal endoscopic surgery for elderly patients with lumbar spinal stenosis. Methods 80 senile patients with lumbar spinal stenosis were collected.According to the treatment methods, they were divided into observation group and control group.40 patients in the observation group underwent percutaneous transforaminal endoscopic treatment, 40 patients in the control group underwent conventional surgical treatment.The operation time, blood loss, hospitalization time, X-ray exposure time, postoperative visual analogue scale(VAS) score and disability index score were compared between the two groups. Results Compared with the control group, the operative time[(61.7±12.4)min vs.(89.3±31.2)min], bleeding volume[(22.3±7.2) mL vs.(192.7±49.1)mL]and hospitalization time[(5.3±1.7)d vs.(11.2±3.7)d]of the observation group were significantly less, while the X-ray irradiation time[(17.1±3.9)min vs.(10.1±3.1)min]was significantly longer.As to VAS incision scores, , postoperative 12h[(4.1±1.5)points vs.(8.3±2.0)points], postoperative 24h[(2.3±1.2)points vs.(7.7±2.1)points], postoperative 48h[(1.3±0.6)points vs.(5.2±1.6)points]and postoperative 72h[(0.5±1.9)points vs.(3.1±1.1)points]in the observation group were significantly lower than those in the control group.Compared with the control group, the ODI scores at 6 months after operation[(11.2±3.6)points vs.(17.2±4.4)points], 12 months after operation[(6.1±1.3)points vs.(10.3±2.5)points]and 24 months after operation[(2.9±0.8)points vs.(6.4±2.1)points]in the observation group were significantly lower, the differences were statistically significant (all P<0.05). Conclusion Minimally invasive treatment of lumbar spinal stenosis with minimally invasive surgery has minimal trauma, less bleeding and shorter hospitalization time.It can significantly improve the symptoms of the incision pain and the functional activities of the limbs, and improve the quality of life of the patients, and it is worthy of further popularization and application.
