[Investigation for Arc of Riolan-Conserving High Ligation Using Simulation CT Colonography in Preoperative Colorectal Cancer].

Background and purpose null Simulation computed tomography colonography(sCTC), which combines CTC and 3-dimensional vascular imaging, is popular for the surgery of colorectal cancer. We experience anomaly, called arc of Riolan(aR), rarely but its definition and details are unclear. Using sCTC, we identified aR and investigated the simulation of aR-conserving high ligation. null Patient and method null The patients were 3 cases of sigmoid...
