People's understanding of lumbar spinal stenosis has become more and more comprehensive and reasonable, however, there are still many controversies about the concepts of "central lumbar canal" and "lateral lumbar spinal canal", and there is no unified standard at present. In this paper, we redefine and differentiate the two concepts. We believe that some kinds of central canal stenosis caused by bilateral recess stenosis can be completely solved by bilateral percutaneous endoscopic transforaminal discectomy. At the same time, the concept of "lumbar lateral recess" is ambiguous. We redefine it as "lateral lumbar spinal canal" and propose "West China Hospital classification" to guide surgical decision-making, which has been widely recognized and applied.
人们对腰椎管狭窄症的认识越来越全面和合理，然而，对于“中央腰椎管”和“外侧腰椎管”的概念仍存在诸多争议，目前尚无统一标准。在本文中，我们对这两个概念进行了重新定义和区分。我们认为，某些由双侧隐窝狭窄导致的中央管狭窄可通过双侧经皮内镜下椎间孔切开术完全解决。同时，“腰椎外侧隐窝”的概念模糊不清。我们将其重新定义为“外侧腰椎管”，并提出“华西医院分类法”以指导手术决策，该方法已得到广泛认可和应用。
