Study Notes
Lymphatic Drainage of Stomach and Small Intestine
- Afferent lymphatics in the stomach wall facilitate communication throughout the tissue.
- Anterior and posterior lymphatics direct drainage towards the stomach's curvatures, where corresponding lymph nodes are located along arterial supplies.
- Cardia drainage is managed by the paracardiac lymph nodes, situated around the cardia and lower end of the esophagus.
- The stomach fundus is drained by splenic lymph nodes found in the gastrasplenic ligament and spleen hilum, along with the left gastroepiploic lymph nodes.
- Efferent lymphatics from fundus nodes travel to the pancreatico-splenic lymph nodes along the splenic artery and upper pancreas border.
- The greater curvature portion of the stomach drains into left and right gastroepiploic lymph nodes.
- The lesser curvature and adjacent stomach sections are drained by left and right gastric lymph nodes.
- The pyloric region’s drainage involves right gastric, right gastroepiploic, subpyloric, retropyloic, and suprapyloic lymph nodes.
- Most lymphatic drainage routes converge at the coeliac lymph nodes, while some may also connect to the superior mesenteric lymph nodes.
