Abstract:Abstract: Objective?To explore the clinical application value of visualization foraminoplasty in treatment of lumbar lateral recess stenosis with endoscopic surgery.?Methods?65 patients with lateral recess stenosis diagnosed lumbar lateral recess stenosis from February 2016 to March 2017 were divided into two groups. 31 patients in the TESSYS group underwent Foraminoplasty with standard TESSYS technique, and 34 patients in visualized group underwent Foraminoplasty with visualization technique. The gender, age, lesion segments, intraoperative C-arm fluoroscopy frequency, operation time, surgical complications, and clinical outcomes were compared between the two groups. At the follow-up time, visual analog scale scores (VAS) were used for low back pain and leg pain. At the final follow-up, the clinical curative effect was evaluated using the Macnab efficacy evaluation criteria.?Results?There was no significant difference in gender, age, and diseased segments between the two groups (P?>?0.05). The number of fluoroscopy and operation time in the visualization group were significantly lower than those in the TESSYS group (P?0.05). The VAS scores of low back pain and leg pain after operation in both groups were significantly lower than before surgery (P?0.05). There was no significant difference in the VAS scores of low back pain and leg pain between the two groups before and after operation (P?>?0.05). According to the Macnab efficacy evaluation standard, there was no statistical difference in the excellent and good rate between the two groups at the final follow-up (P?>?0.05).?Conclusion?The short-term clinical efficacy of visual foraminoplasty in treatment of Lumbar Lateral Recess Stenosis is comparable to that of the standard TESSYS technique. Visual foraminoplasty has less intraoperative fluoroscopy times, simplified procedure, and shorter operation time, safety, and low interference with lumbar joint stability.
