Abstract
Objective To investigate the efficacy of percutaneous endoscopic lumbar discectomy for the treatment of lumbar disc herniation. Methods Under local anesthesia,48 patients(oberserve group) with single lumbar disc herniation were treated by percutaneous endoscopic lumbar discectomy, and the spinal cord and the nerve root were decompressed under the guidance of the C-arm X-ray machine. The visual analogue scale (VAS) of preoperative and postoperative 1 month and final follow up of patients was used for the pain assessment, and at the same time the modified MacNab criteria was used for efficacy assessment, compared with 40 cases of percutaneous endoscopic discectomy patients( control group). Results Observe the operation time( 62.7 ± 12. 3) min and hospital stay (4.6 ± 1.2) d was significantly lower than the control group (87. 2 ± 16. 7) min, (8. 9 ± 3. 7) d, after 1 month (3.13 ±0.76) and the final follow-up( 1.35 ±0.23) VAS scores were lower than the control group(4.85 ± 1. 24) (2.64 ±0. 81) ( P ＜ 0. 05) , using modified Macnab criteria to evaluate the clinical efficacy, excellent observation group was 77.1 % , significantly higher than 62.5 % (P ＜ 0.05 ). Conclusion The efficacy of percutaneous endoscopic lumbar discectomy for the treatment of lumbar disc herniation was positive,but it should be strictly to master surgical indications. Key words: Intervertebral disk displacement; Diskectomy,percutaneous
