Left colon conduits are usually based on the ascending branch of the left colic artery (LCA). The middle colic artery (MCA) is divided proximal to its bifurcation into right and left branches. The resulting grafts consist of portions of transverse colon, splenic flexure, and sigmoid colon (ICA = ileocolic artery; RCA = right colic artery; SMA = superior mesenteric artery.)
