NCT03826862

Brief Summary

The investigators will perform CT three-dimension reconstruction for middle-low rectal cancer patients who have enlarged lateral lymph nodes to recognize the variance of pelvic vessels, by which to help reduce operative time and blood loss, localize the lateral lymph nodes, improve the lymph node harvested and positive rate. Besides, The investigators will label the vessels near the interested node to achieve node-by-node for further investigation.
