Comparison Between ex Vivo and in Vivo Injection of Blue Dye in Sentinel Lymph Node Mapping for Colon Cancer

The technique of sentinel lymph node mapping in patients with colon cancer varies among reports, and the optimal method remain to be established. The purpose of this study was to determine the optimal injection technique for sentinel lymph node mapping for colon cancer.

Inclusion Criteria:

• Stage I - III colon cancer patients

Exclusion Criteria:
