%X Before the "mesorectal" theory was proposed, the traditional anatomy believed that the "pelvirectal space" belonged to the anal canal and perirectal space, which was independent of the rectal structure, located on both sides of the rectum, above the levator ani, and below the peritoneal reflexion, and was composed of a large amount of fatty tissue filling. With the development of the theory of membrane anatomy and the clarification of the concept of "rectal mesentery", combined with the author's clinical experience, we found that the above-mentioned fat is actually the fat within the mesorectum, as well as the fat tissue of lateral lymph nodes (LLN) such as the internal iliac lymph nodes (No.263) and obturator lymph nodes (No.283) on both sides of the rectal mesentery, rather than the so-called fat tissue within the interstitial space. Therefore, the author believes that the pelvirectal space does not exist. In the anatomical location equivalent to the pelvic rectal space, there is the "superior levator ani space" based on the membrane anatomy theory. From the pelvirectal space to the superior levator anal space, it reflects our further understanding of the anatomy of the rectal mesentery.<BR>在提出“直肠系膜”理论之前，传统解剖学认为“骨盆直肠间隙”属肛管、直肠周围间隙，其独立于直肠结构之外，位于直肠两侧的、肛提肌上方的、腹膜反折下方的间隙，由大量脂肪组织填充组成。而随着膜解剖理论的发展、“直肠系膜”概念的明确，结合笔者临床经验，我们发现上述的脂肪其实是直肠系膜内的脂肪，及直肠系膜两侧的髂内淋巴结（No.263）和闭孔淋巴结（No.283）等侧方淋巴结脂肪组织，并不是所谓间隙内的脂肪组织。因此，笔者认为骨盆直肠间隙是不存在的，在相当于骨盆直肠间隙的解剖位置，存在的是基于膜解剖理论的“肛提肌上间隙”。从骨盆直肠间隙到肛提肌上间隙，体现的是我们对于直肠系膜的解剖认识的进一步升华。.
