Optimal Ligation Level of the Primary Feeding Artery and Bowel Resection Margin in Colon Cancer Surgery: The Influence of the Site of the Primary Feeding Artery

Abstract

In T1 tumors, central node dissection is not required, but resection with proximal and distal 3-cm margins are required; in T2, central node dissection that includes the intermediate node should be performed in addition to resection with proximal and distal 5-cm margins. In T3 and T4, central node dissection that includes the main node should be performed in addition to resection with proximal and distal 7-cm margins. However, for T2 more than 5 cm from the primary feeding artery, and for T3 more than 7 cm from the primary feeding artery, proximal and distal resection alone may be adequate.
