よくある質問

What is an abdominal lymph node?
An abdominal lymph node (known in anatomical terminology as abdomen lymph node) is a small, bean-shaped immune organ located within the abdomen. Like all lymph nodes, it filters lymph fluid and houses immune cells that detect and respond to pathogens, cancer cells, and foreign materials.
Where are abdominal lymph nodes located?
Abdominal lymph nodes are distributed throughout the abdominal cavity, including groups associated with the celiac axis, mesenteric vessels, para-aortic region, and along the major branches of the abdominal aorta. They drain lymph from the abdominal organs and intestines.
What is the function of abdominal lymph nodes?
Abdominal lymph nodes filter lymph fluid from the digestive organs and abdominal structures, removing bacteria, cancer cells, and debris. They also play a central role in immune responses by activating T and B lymphocytes against antigens from the gastrointestinal tract.
What conditions can affect abdominal lymph nodes?
Abdominal lymph nodes may become enlarged (lymphadenopathy) due to infection, inflammatory bowel disease, or malignancy. Gastrointestinal cancers commonly spread (metastasize) to regional mesenteric and para-aortic lymph nodes, and their involvement has important staging implications.
What are the main groups of abdominal lymph nodes?
Key groups include the celiac nodes (draining the upper GI tract), the superior and inferior mesenteric nodes (draining the intestines), the pre-aortic and lateral aortic (para-aortic) nodes, and the hepatic, splenic, and renal nodes associated with their respective organs.
