Abstract： In order to increase the blood supply of anastomosis, surgeons choose to preserve the left colon artery (LCA) during the laparoscopic radical resection of rectal cancer. However, surgeons are always ailed by hemorrhage and incompletely dissection of No. 253 lymph nodes. One reason is the shortage of understanding the relationship between inferior mesenteric artery (IMA), LCA, and inferior mesenteric vein before surgery. Another reason is that surgeon always remove the lymph nodes around LCA, while don′t normatively resect No. 253 lymph nodes, which affect the overall survival rate. Therefore, the "medial-to-lateral approach" for laparoscopic preservation with LCA radical resection in rectal cancer was suggested in this article. The CT technique could be used to analyze the IMA classification, which contribuated to the standard conservation of LCA. Laparoscopic radical resection of rectal cancer could be completed of high quality, through accurate definition and exactly dissection of the No. 235 lymph nodes.
