对“直肠侧韧带”的认识与思考

Cognition and reflection on the"lateral ligament of rectum"

随着全直肠系膜切除术在我国的广泛开展,直肠侧韧带作为直肠侧的一个重要解剖结构,具有一定的解剖价值和临床意义,一直是人们关注的焦点。本文通过对比分析腹盆韧带的特点,回顾膜解剖学和原肠旋转理论,结合临床观察和组织学研究,得出我们的结论:直肠侧韧带并不存在,它只是直肠侧的一个相对致密的间隙,并伴有无数细小的神经丛和小血管穿透其中。

As total mesorectal excision(TME)for rectal cancer is widely carried out in China,lateral ligament of rectum,as an important anatomical structure of the lateral rectum with certain anatomical value and clinical significance,has been the focus of attention.In this paper,by comparing and analyzing the characteristics about ligaments of the abdomen and pelvis,reviewing the membrane anatomy and the theory of primitive gut rotation,and combining clinical observations and histological studies,the author came to a conclusion that lateral ligament of rectum does not exist,but is only a relatively dense space on the rectal side accompanied by numerous tiny nerve plexuses and small blood vessels penetrating through it.
