| ABSTRACT Abstract Objective To : To investigate the early clinical effects of Transforaminal Endoscopic Spine System for the treatment of patients with single-stage bilateral lumbar disc herniation. METHODS: Retrospective analysis was performed on 38 cases of single-stage bilateral lumbar disc herniation treated with percutaneous transforaminal borescope TESSYS from February 2016 to February 2018. There were 26 males and 12 females with an average age of 35.2±6.4. Aged (30-55 years old); of these, 6 were L3/4, 22 were L4/5, and 10 were L5/S1. Using the intervertebral foramen of the German joimax GmbH, local anesthesia, bilateral puncture to the outside of the intervertebral foramen of the diseased segment, four-stage dilatation catheter to complete the progressive enlargement of the intervertebral foramen, and the ring saw progressively enlarge the intervertebral foramen The bilateral foramen was placed and the herniated nucleus was removed until the nerve root was completely released. Postoperatively, the patients were reviewed on regular outpatient visits and telephone follow-ups. Visual analogue pain scores VAS and Oswestry disability index (ODI) were compared before and after surgery in January, March, June, and December, respectively. The final telephone follow-up assessment of the patient''s surgical outcome was assessed using the modified MacNab evaluation criteria. Results : The VAS scores and ODI scores of low back pain in lower extremities after 1, 3, 6 and 12 months postoperatively were statistically significant (P<0.05), and they were doubled between January and March and after 6 and 12 months postoperatively. The difference of VAS scores and ODI scores in lower back pain was statistically significant (P<0.05), and the VAS scores and ODI scores of low back pain in both lower limbs in January and March, and in June and December in the postoperative period. There was no significant difference between statistics (P>0.05). According to the modified MacNab evaluation criteria, the final follow-up was excellent in 14 cases (38.9%), good in 16 cases (44.4%), fair in 4 cases (11.1%), and poor in 2 cases (5.6%). ), Good rate 83.3%. Conclusion: The use of percutaneous transforaminal telescope TESSYS technique to remove the herniated nucleus from both sides while fully decompressing the nerve root can be effectively applied to patients with single-stage bilateral lumbar disc herniation. |
