Nodal Metastases in the Gastrohepatic Ligament

Tumors arising from the area of the stomach along the lesser curvature and the esophagogastric junction, supplied by the left gastric artery, generally metastasize to the lymph nodes in the gastrohepatic ligament. The primary nodal group (N1 station) consists of nodes along

the left and right gastric artery anastomosis along the lesser curvature. The N2 station includes the nodes along the left gastric artery and vein in the gastropan-creatic fold (Figs. 6-8 and 6-9) that drain toward the suprapancreatic nodes along the superior border of the body of the pancreas (Fig. 6-8) and then the celiac axis (N3 station).

Tumors arising from the area of the stomach supplied by the right gastric artery, including the lesser curvature of the antrum and pylorus, drain into the nodes in the hepatoduodenal ligament (Fig. 6-8), where the right gastric artery originates from the hepatic artery or the right gastric vein drains into the portal vein. From these nodes, drainage continues along the hepatic artery toward the celiac axis.

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
