Nodal Metastases in the Gastrocolic Ligament

Primary tumors involving the greater curvature of the antrum of the stomach in the distribution of the right gastroepiploic artery spread to the perigastric nodes (N1 station) accompanying the right gastroepiploic vessels that course along the greater curvature of the stomach. They drain into the nodes at the gastrocolic trunk (N2 station) (Fig. 6-10) or the nodes at the origin of the right gastroepiploic artery and the nodes along the gas-troduodenal artery (the subpyloric or retropyloric node). From there, they can proceed to the celiac axis or the root of the superior mesenteric artery.

(a) Primary tumor (T) at EG junction with metastatic perigastric node (N) in gastrohepatic ligament, an N1 station.

(b) Nodes (N) in gastropancreatic fold along left gastric vessel (white arrow), an N2 station.

(c) Nodes (N) at suprapancreatic nodes, N2 station, along splenic artery draining from posterior wall of fundus to splenic hilum via gastrosplenic ligament. Also note common hepatic artery node (black arrow), N2 station, anterior to common hepatic artery (white arrow) draining along left and right gastric anastomosis.

(d) Left inferior phrenic node (N), N3 station, located at apex of adrenal gland draining from left diaphragm at esophageal hiatus along left inferior phrenic vessels where they drain into left renal vein.
