- Abstract: 【Objective】 To compare the clinical effect of single channel-spinal endoscopy （Delta） and unliateral biportal endoscopic technique （UBE） for the treatment of senile lumbar spinal stenosis. 【Methods】 We retrospectively analyzed 48 elderly patients with lumbar spinal stenosis treated between February and October 2020. The patients were divided into single channel-spinal endoscopy （Delta） group （n=25） and UBE group （n=23） according to different surgical methods. We compared the operation time， intraoperative blood loss， length of hospital stay， and surgical complications between the two groups. The visual analogue score （VAS） and Oswestry disability index （ODI） were compared between the groups. 【Results】 Single channel-spinal endoscopy （Delta） group was significantly inferior to UBE group in operation time （P<0.05）. There was no significant difference in intraoperative blood loss or length of hospital stay between the two groups （P>0.05）. The VAS scores at 24， 48， and 72 postoperative hours did not differ between the two groups （P>0.05）. The ODI scores at 3 postoperative months and final follow-up were significantly improved over the preoperative score in both groups （P<0.05）， but without significant difference in postoperative ODI score between the groups （P>0.05）. The incidence rate of complications was 8% （2/25） in single channel-spinal endoscopy （Delta） group and 9% （2/23） in UBE group， and no significant difference was found （P>0.05）. 【Conclusion】 Single channel-spinal endoscopy （Delta） and UBE technique both achieve satisfactory clinical efficacy in the treatment of senile lumbar spinal stenosis. but the former one exhibits advantages over the latter in easier performance and lower learning curve. Single channel-spinal endoscopy （Delta） is an efficacious minimally invasive surgical technique for treating senile lumbar spinal stenosis.
