Nodes clustered at the roots of the three midline visceral arteries collect all gut, liver, spleen and pancreatic lymph, and their efferents unite as the intestinal trunk.

D2 gastrectomy is designed to take the coeliac nodal stations
Colonic carcinoma with mesenteric nodal involvement
Stage III disease requiring adjuvant chemotherapy; at least 12 nodes needed to call the specimen node-negative
