Abstract:

Objective    To discuss the clinical curative effect and safety on the treatment for multi-level lumbar disc herniation with one hole percutaneous endoscopic technique.    Methods    26 patients，from January 2014 to July 2018，diagnosed as multi-level lumbar disc herniation，were observed. All patients were treated with the one hole percutaneous endoscopic technique under the local anesthesia. The Oswestry disability index (ODI), visual analogue scale (VAS) and NaKai excellent rate preoperative，6 months after surgery and 1year after surgery were used to analyze clinical curative effect and security.   Results   25 patients got NaKai excellent, 1 patient got relapse, and 0 patient inefficacy. Total NaKai excellent rate was 96.2%. VAS score was（6.18±0.28）preoperatively, (3.24±0.46) 3 months after surgery, and（2.64±1.27）6 months after surgery, and (1.44±1.16) 1 year after surgery. The VAS score was significantly lower than the preoperative score from 3 months to 1 year after surgery. The difference was statistically significant. The difference between preoperative and postoperative ODI was statistically significant（P<0.05）. Postoperative lumbar pain and lower limb numbness and pain were alleviated in 26 patients. Intraoperative small incision, less bleeding, short postoperative hospital stay, early time to go to the ground, and quality of life got improved.  Conclusion  Treatment of multi-segment lumbar disc herniation with one hole percutaneous endoscopic technique shares the advantage of being less traumatic, safe and effective, making it worthy of clinical application and promotion.
