High Tie Versus Low Tie Vascular Ligation of the Inferior Mesenteric Artery in Colorectal Cancer Surgery

The gain in colonic length is 10 cm greater for high-tie vascular transections. With low-tie vascular transections, high inferior mesenteric vein division produced a small additional gain in length, and secondary left colic artery division produced the same length gain as high-tie vascular transections.
