Clinical outcomes of percutaneous transforaminal endoscopic discectomy and Quadrant minimally invasive system in treatment of lumbar disc herniation / 中国内镜杂志

ABSTRACT

Objective To compare the clinical efficacy of percutaneous transforaminal endoscopic discectomy (PTED) and Quadrant minimally invasive system in treatment of lumbar disc herniation (LDH). Methods 59 single-level LDH patients were randomly divided into PTED group (n = 31) and Quadrant group (n = 28). Then compare the operative time, incision length, blood loss, length of hospital stay, and the return-to-work time between the two groups. In addition, visual analogue scale (VAS), Japanese Orthopedic Association (JOA), Oswestry disability index (ODI), and modified MacNab criteria were used for surgical efficacy evaluation. Results In PTED group, compared with Quadrant group, we observed, shorter incision length, less blood loss, shorter hospital stay, and shorter time of returning to work (P 0.05). According to the improved MacNab criteria, there was no significant difference in excellent or good rate between the two groups (P > 0.05). Conclusion The clinical results of PTED and Quadrant minimally invasive system in treatment of lumbar disc herniation were satisfactory, and PTED were less traumatic method with rapid recovery.
