Lymph from the lesser curvature of the stomach drains chiefly into which group of nodes?

• A Left gastric nodes along the left gastric artery ✓
• B Pancreaticosplenic (splenic hilar) nodes
• C Right gastroepiploic nodes along the greater curvature
• D Infrapyloric nodes

Explanation

Lymphatics of the stomach follow the arterial supply. The lesser curvature drains into left gastric nodes along the left gastric artery, which then drain to the coeliac nodes. The fundus and greater curvature drain to pancreaticosplenic and left gastroepiploic nodes, and the pyloric region drains to right gastroepiploic and infrapyloric nodes. This arterial territory rule also underlies D2 gastrectomy nodal clearance levels.
