Abstract:

Colorectal cancer is one of the most common malignant digestive tumors, of which colectomy combined with regional lymphadenectomy is the standard treatment. However, the extent of lymphadenectomy has not reached a consensus. The concept of complete mesocolic excision (CME) with central vascular ligation (CVL) proposed by European surgeons has not made a clear definition about the margin of lymph node excision, while D3 lymphadenectomy proposed by Japanese guideline proved to have more perioperative risks, which seems some kind of over-treatment. In our country, right hemicolectomy standard has not been established, surgeons perform right colectomy following the CME strategy and lymphadenectomy following D2/D3 excision standard. So, we reviewed the characteristics of lymph node metastasis of right colon cancer, and the advantages and disadvantages of D2/D3 lymphadenectomy.

Key words: Colonic neoplasms, Right colon cancer, The extent of lymphadenectomy, D2 lymphadenectomy, D3 lymphadenectomy
