What are the celiac lymph nodes?

A group of preaortic lymph nodes that receive lymph from the foregut and its associated digestive organs.

In This Section

1. What are the celiac lymph nodes?

A group of preaortic lymph nodes that receive lymph from the foregut and its associated digestive organs.

2. Where are the celiac lymph nodes located?

Around the origin of the celiac trunk on the anterior surface of the abdominal aorta.

3. At approximately which vertebral level are the celiac lymph nodes located?

Near the T12 vertebral level.

4. To which major abdominal lymph node category do the celiac nodes belong?

The preaortic lymph nodes.

5. In which anatomical compartment are the celiac lymph nodes situated?

The retroperitoneum of the upper abdomen.

6. Which embryological division of the gastrointestinal tract primarily drains to the celiac lymph nodes?

The foregut.

7. Which gastrointestinal organs contribute lymph to the celiac lymph nodes?

The abdominal esophagus, stomach, and proximal duodenum.

8. Which accessory digestive organs drain lymph toward the celiac lymph nodes?

The liver, gallbladder, pancreas, and spleen.

9. Which regional lymph node groups carry lymph from the stomach toward the celiac nodes?

The gastric, gastro-omental, and pyloric lymph node groups.

10. Which lymph nodes along the lesser curvature of the stomach drain toward the celiac nodes?

The left and right gastric lymph nodes.

11. Which lymph node group commonly receives lymph from the liver before it reaches the celiac nodes?

The hepatic lymph nodes along the hepatic vessels and within the hepatoduodenal ligament.

12. Through which lymph node groups does lymph from the gallbladder commonly reach the celiac nodes?

The cystic and hepatic lymph nodes.

13. Which lymph node groups drain much of the pancreas toward the celiac nodes?

The pancreaticosplenic and pancreaticoduodenal lymph node groups.

14. Which lymph nodes receive lymph from the spleen before it reaches the celiac nodes?

The pancreaticosplenic lymph nodes along the splenic vessels.

15. Which lymph node groups can receive lymph from the proximal duodenum?

The pyloric and pancreaticoduodenal lymph nodes.

16. What is the principal function of the celiac lymph nodes?

To filter lymph arriving from foregut organs before its passage into central lymphatic collecting vessels.

17. Which major lymphatic trunk receives efferent vessels from the celiac lymph nodes?

The intestinal lymphatic trunk or trunks.

18. Which lymphatic reservoir commonly receives lymph from the intestinal trunks?

The cisterna chyli, when present.

19. Which major lymphatic vessel transports lymph from the celiac drainage territory toward the venous circulation?

The thoracic duct.

20. How do the celiac nodes differ from the superior mesenteric lymph nodes?

Celiac nodes primarily receive foregut lymph, while superior mesenteric nodes primarily receive midgut lymph.

21. Which autonomic nerve plexus is closely associated with the celiac lymph nodes?

The celiac plexus.

22. Why are celiac lymph nodes clinically important in gastric cancer?

They can receive metastatic tumor cells through gastric lymphatic drainage pathways.

23. Why are the celiac lymph nodes relevant in pancreatic cancer staging?

Pancreatic tumors may spread to celiac nodes through regional pancreatic lymphatic pathways.

24. Why are celiac lymph nodes evaluated during surgery for upper gastrointestinal malignancies?

Their involvement helps determine the extent of lymphatic tumor spread and appropriate lymph node dissection.

25. Which imaging technique is commonly used to assess enlarged celiac lymph nodes?

Contrast-enhanced computed tomography of the abdomen.
