Clinical Trial Summary

The vascular branches of inferior mesenteric artery (IMA) involve superior rectal artery(SRA),Sigmoid artery(SA) and the left colic artery(LCA). Different levels of ligation of the (IMA) are applied in rectal cancer surgery, including retain or not retain the left colic artery(LCA). Retained the LCA would facilitate the vascularity. The variations of vessels are more frequent in the combinations of branches, while LCA, SA and SRA may vary from people to people. Which contribute to the difficulty of surgery to retain the LCA.. As a result, a better understanding of the anatomical branches classification of IMA is a must during operation. However, existing studies of IMA's branches combination are very rare and often single-centered with minimal samples. In order to achieve better surgical outcome and reduce operative complications, the investigators design this study to investigate the anatomical classification of IMA and the surgical outcome of each type
