Definition
The visceral abdominal lymph nodes are a complex network that primarily follow the course of the major arteries supplying the abdominal organs. These nodes are categorized based on their anatomical locations and the organs they drain in the Terminologia Anatomica:
Celiac nodes: around the celiac trunk and receive lymph from the stomach, liver, spleen, pancreas, and upper duodenum.
Right gastric nodes: on the lesser curvarture of stomach along the branches of the right gastric artery.
Left gastric nodes: on the lesser curvarture of stomach along the branches of the left gastric artery.
Right gastroomental nodes: on the greater curvature lymph nodes along the right gastrooemental artery
Left gastroomental nodes: on the greater curvature lymph nodes along the left gastrooemental artery
Pyloric nodes: in the region of the pylorus near the head of the pancreas
Pancreatic nodes: superior and inferior nodes around the body and the tail of the pancreas.
Splenic nodes: at the hilum of the spleen.
Pancreaticoduodenal nodes: in the region of the head of pancreas
Hepatic nodes: near the hilum of the liver and in the hepatoduodenal ligament.
Superior mesenteric nodes: around the superior mesenteric artery, these nodes drain the small intestine, cecum, ascending colon, and part of the transverse colon.
Inferior mesenteric nodes: around the inferior mesenteric artery, these nodes collect lymph from the descending colon, sigmoid colon, and upper rectum.
These nodes are categorized based on their drainage in different type of cancer, like the classification of nodal stations in gastric cancer from Japanese Research Society for Gastric Cancer.
