ABSTRACT
Colon cancer is one of the most common malignancies of the alimentary tract, and one main metastatic route is lymph node metastasis. Thorough dissections of regional lymph nodes is one of the core surgical treatment of right colon cancer. D3 lymphadenectomy and complete mesocolic excision (CME) are generally accepted surgical methods for right colon cancer, which can improve the standardization of surgery, improve the quality of tumor resection, and provide more lymph nodes dissectal. Colon cancer of hepatic flexure is likely to have metastasis of the infrapyloric lymph nodes (No.206), which are not regional lymph nodes. Lymph node dissection of No.206 group belongs to extended right hemicolectomy, which involves many vascular variations and complicated peripheral anatomical structure. The theory of fascial surgery provides surgeons with anatomic basis and a clear understanding of the anatomical structure of the infrapyloric region, which is an important theoretical basis for the thorough dissection of lymph nodes in No.206 group, and can completely remove the mass, regional lymph nodes and adipose connective tissue, so as to achieve the goal of non-bleeding surgery. Lymph nodes in No.206 group were dissected, not just the visible lymph nodes, but the entire lymph nodes and lymphatic vessels in the region, including adipose tissue. Extended right hemicolectomy requires higher surgical techniques. The survival benefits of extended right hemicolectomy are not supported by high-level evidence. It is still controversial whether the infrapyloric lymph node dissection should become routine for colon cancer of hepatic flexure. In this article, the metastasis and dissection of infrapyloric lymph node in colon cancer of hepatic flexure is elucidated.
