Abstract
Background: There is still a discussion in the literature about the location of inferior mesenteric artery (IMA) ligation during D3 lymph node dissection for colorectal cancer (CRC). Ligation of the IMA below the branching of left colic artery (LCA) preserves this important vessel for adequate blood supply to the left colon and thus reduces the risk of anastomotic leakage [1,2].
