| Objective To study the clinical effect of percutaneous transforaminal endoscopic discectomy technique in the treatment of degenerative lumbar spinal stenosis. Methods A total of 74 patients with degenerative lumbar spinal stenosis were treated by percutaneous transforaminal endoscopic discectomy during July 2015 to March 2017 in the 1st People's Hospital of Kunming City. The visual analogue scale(VAS) and Oswestry disability index(ODI) were used to evaluate the degree of pain and the clinical efficacy in each patient before and after operation. Results The operation time was 70 to 150 min, the blood loss was 10 to 40 mL, and the hospital stay was 3 to 8 days without serious complications. All patients were followed up for an average of 36 days after surgery. The preoperative VAS score was (6.96±0.74) points, and the VAS scores were (3.13±0.63), (2.44±0.87) and (2.15±0.75) points at 1 day, 1 week, and 1 month after operation. The preoperative ODI score was (39.07±11.58) points, and the ODI scores were (19.88±6.39) points, (18.75±5.84) points, and (15.21±5.21) points at 1 day, 1 week, and 1 month after operation. The postoperative VAS score and ODI score were significantly improved compared with that before operation, and the difference was statistically significant (P<0.05). Conclusion Percutaneous intervertebral foraminal technology in the treatment of degenerative lumbar spinal stenosis has the advantages of less trauma, less bleeding and fewer complications, and the short-term clinical effect is satisfactory. |
