Clinical Effectiveness of Percutaneous Full-endoscopy Spine Surgery Combined With Holmium Laser in the Treatment of Lumbar Disc Herniation
Abstract Background Oxidative stress has been considered a critical mediator in the pathogenesis of lumbar disc degeneration, which can lead to the severe lower back pain. Inhibition of the excessive oxidative stress has become a therapeutic target for controlling discogenic lower back pain. Recently, more studies have shown that holmium laser can effectively suppress oxidative stress. This work aims to study the clinical outcomes of percutaneous full-endoscopy spine surgery combined with holmium laser for treating symptomatic lumbar disc degeneration (IDD). Methods We designed and conducted a retrospective study on the patients with lumbar disc herniation who had been treated by percutaneous full-endoscopy spine surgery at Shanghai General Hospital from June 2018 to March 2020. The patients were divided into group A (holmium laser treatment group) and group B (Elliquence radiofrequency group) according to the medical record. Operation time and hospitalization time of both groups were recorded and compared. Additionally, VAS scores and ODI scores were used to evaluate the lower back pain, lower extremity radiation pain and quality of life before and 3 days, 6 months, and 12 months after surgery. Results Forty-five patients were included in group A while the other 55 patients were included in group B. Operation time of group A was significantly shorter than that of group B (40.60±5.59 minutes vs. 50.80±3.19 minutes). VAS scores of lower back pain and lower extremity radiation pain at postoperative 3 days, 6 months, and 12 months were significantly lower than those before surgery in both groups. The postoperative lower back pain VAS scores of group A were significantly lower than those of group B, while the postoperative lower extremity radiation pain VAS scores had no significant difference between both groups. The ODI scores of both groups at postoperative 3 days, 6 months, and 12 months were significantly lower than those before surgery. Conclusions These findings confirmed that application of holmium laser can significantly improve the clinical outcomes in percutaneous full-endoscopy spine surgery.
