Correct Answer: Preaortic nodes
Description: Lymphatic drainage of stomach
The stomach can be divided into four lymphatic territories . The drainage of these areas is as follows.
Upper part of left 1/3rd drains into the pancreaticosplenic nodes lying along the splenic artery, i.e. on the back of the stomach. Lymph vessels from these nodes travel along the splenic artery to reach the coeliac nodes.
Right 2/3rd drains into the left gastric nodes lying along the artery of the same name. These nodes also drain the abdominal part of the oesophagus. Lymph from these nodes drains into the coeliac nodes.
Lower part of left 1/3rd drains into the right gastroepiploic nodes that lie along the artery of the same name. Lymph vessels arising in these nodes drain into the first and second parts of the duodenum. From here the lymph is drained further into the hepatic nodes that lie along the hepatic artery; and finally into the coeliac nodes.
Lymph from i.e. pyloric part drains in different directions into the pyloric, hepatic, and left gastric nodes, and passes from all these nodes to the coeliac nodes.
Note that lymph from all areas of the stomach ultimately reaches the coeliac nodes. From here it passes through the intestinal lymph trunk to reach the cisterna chyli.
