The winner for D2 lymph node dissection in distal gastrectomy —anatomic landmarks vs. number of examined lymph nodes

Jiping Wang


Although D2 lymph node dissection in treating gastric cancer has been considered as a standard care in Asia, the standardization and adoption of this procedure in non-tertiary medical center remains a real challenge. One of the major obstacles is the complexity of the peri-gastric lymph node distribution, perigastric spaces and the relationships among stomach, major blood vessels, colon, pancreas and spleen. For low incidence geographic area, such as in US or Europe, this surgery is even more challenging since most of the centers treat less than 20 cases/year. This manuscript illustrated the anatomical landmarks for D2 lymph node dissection in distal gastrectomy in order to facilitate the learning process and achieve the standardization of this surgical procedure.
