Anatomical terminology

The inferior mesenteric lymph nodes consist of:

Structure

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

Contents

Afferents

The inferior mesenteric lymph nodes drain structures related to the hindgut; [1] they receive lymph from the descending colon, sigmoid colon, and proximal part of the rectum. [2]

Efferents

They 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]

Clinical significance

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. [3] This has been proposed since at least 1908, by surgeon William Ernest Miles. [4]
