title: Colon cancer complicated by vascular and intestinal anomaly.
abstract: We present a case of colon cancer in a patient with an anomalous mesenteric artery, a middle mesenteric artery, associated with intestinal nonrotation. At surgery for such a rare case, an exact grasp of the feeding artery, the draining vein, and the lymphatic flow of the tumor is necessary to perform appropriate bowel resection and oncological nodal dissection. Selective angiography and preoperative endoscopic submucosal injection of India ink near the tumor were thought to be essential for surgical decision-making.
