Objective: To investigate the clinical effect of transforaminal endoscopic technology for elderly lumbar disc herniation combined with lateral recess stenosis patients. Methods: One hundred and twenty cases of elder patients with lumbar disc herniation with lateral recess stenosis in our hospital were randomly divided into a research group and a control group, 60 cases in each group. The research group were treated with percutaneous transforaminal technique discectomy, while the control group were treated with subtotal laminectomy incision and laminectomy incision. Lumbar function, visual analogue scale (VAS) of waist and leg of the two groups were tested before surgery and 3, 6 months after surgery. The lumbar function and its excellence rate evaluated by Macnab, operation time, incision length, blood loss, hospital stay time, and VAS of two groups were compared 6 months after surgery. Results: The Macnab evaluation’s excellent rate of the research group was signigicantly higher than that of the control group (P<0.05). The operation time, incision length, hospital stay time of the research group were significantly shorter than those of the control group (P<0.05). The blood loss of the research group was significantly less than that of the control group (P<0.05). There was no significant difference in VAS of waist and leg between two groups 6 months before and after surgery (P>0.05). VAS of waist and leg of research groups was significantly lower than control group (P<0.05) 3 months after surgery. Conclusion: Transforaminal endoscopic technology has exactly effect on elderly lumbar disc herniation combined with lateral recess stenosis. Patients lose less blood and recovery is fast after surgery. It is worthy of widely used.
