Effect of METRx endoscope-assisted X-tube for the treatment of lumbar disc herniation

Objective To investigate the effect of decompressive laminectomy and discectomy under METRx endoscope-assisted X-tube in the treatment of lumbar disc herniation.Methods 13 patients with lumbar disc herniation underwent decompressive laminectomy and discectomy using x-tube operation system,including lumbar disc herniation of L4/5 in 7 cases,L5/S1 in 6.According to Macnab scale,the surgery effect,operative time,intraoperative blood loss and complications were evaluated.Results All operation were completed successfully,and the patients were fellowed up with an average of 6 months(range from 3 to 12).Macnab sacle: excellent in 10 cases,good in 3 cases at the third month follow-up after operation.Operative time were 60 min(45-105 min),intraoperative blood loss were 30 mL(10-95 mL).No complications were found.Conclusion With minimally invasive effect and direct vision,the decompressive laminectomy and discectomy using x-tube operation system has advantage for treatment of lumbar disc herniation.It is a key for successful operation to strict indication and standard operating.
