The inferior mesenteric lymph nodes consist of:

Structure[edit]

The inferior mesenteric lymph nodes are lymph nodes present throughout the hindgut. [1]

Function[edit]

The inferior mesenteric lymph nodes drain structures related to the hindgut. The lymph nodes drain into the superior mesenteric lymph nodes and ultimately to the preaortic lymph nodes.[1] Lymph nodes surrounding the inferior mesenteric artery drain directly into the preaortic nodes. [1]

They drain the descending colon and sigmoid parts of the colon and the upper part of the rectum.

Clinical significance[edit]

Colorectal cancer may metastasise to the inferior mesenteric lymph nodes. For this reason, the inferior mesenteric artery may be removed in people with lymph node-positive cancer.[2] This has been proposed since at least 1908, by surgeon William Ernest Miles. [3]
