简要总结
Different procedure of percutaneous endoscopic lumbar discectomy (PELD) was with ventral decompression of dural sac on the lumbar spinal stenosis remains unkonwn.The traditional transforaminal endoscopic spine system (TESSYS) of PELD has been used in clnical for many years, but cannot achieve dorsal decompression. A newly developed modified TESSYS procedure, "U" route PELD combining ventral and dorsal decompression was introduced. Nevertheless, the superior between TESSYS and "U" route PELD procedures on treating LSS remains unknown. This study is desinged to recruit degenerative lumbar spinal stenosis patients who underwent TESSYS or "U" rout PELD, recruited from January 2014 to December 2017. These patients will be followed up for 2 years, and assessed the minimum dura sac cross sectional area (mDCSA) by MRI, and visual analogue scale (VAS) and Oswestry Disability Index (ODI) at pre- and post-operation. The global clinical outcomes were evaluated using modified MacNab criteria postoperatively. Thus, comprehensively evaluate the safety and therapeutic effects of the two PELD procedures on LSS treatments.
