There had been many controversies about resection margin of bowel and limit of<br>lymph node dissection in the right hemicolectomy. With an idea of 1ymphovenous<br>drainage in the right colonic cancer, the main artery of tumor was infused with<br>flurescein dye(Fluorescite 10％, Alcon Lab.) for the purpose of determining the resection<br>margin accurately Lymph nodes of the principal and intermediate group were also<br>dissected on bloc with the regional resection of bowel. We have tried the procedure in<br>the 10 patients of the right colonic cancer. Resection margin at the oral side and the<br>rejected lymph nodes were increased comparing the 11 patients of traditional right<br>hemicolectomy. In conclusion, successive development of surgical techniques should keep<br>pace with new knowledge of microstructure of lymphovascular system and tumor<br>biology in the surgery of colonic cancer.<br>
