Radio-surgical agreement on the inferior mesenteric artery ligation level in left colon and rectal cancer
Studies on postoperative, functional, and oncological outcomes in left colon cancer (LCC) and rectal cancer (RC) surgery have been based exclusively on the surgeon’s judgment of the inferior mesenteric artery (IMA) ligation level [1, 2, 3]. However, the accuracy of such an evaluation has been poorly investigated. Contrast-enhanced computed tomography (CT) scanning has proven to be useful for postoperative assessment of the vascular ligation level in patients with colon cancer [4, 5].
We retrospectively analyzed preoperative and postoperative multidetector CT (MDCT) images of patients who underwent LCC and RC resection at Hospital de Clínicas de Porto Alegre, Brazil, between 2015 and 2017. Exclusion criteria were multivisceral resection, contraindication for using intravenous contrast agent, prior colorectal resection, unclear information regarding the IMA ligation level, or IMA thrombosis. All surgical procedures were performed by a fourth-year resident of colorectal surgery...
