Lymphatics of Colon

(Jamieson and Dobson.)


Mesocolic Glands (lymphoglandulæ mesocolicæ) are numerous, and lie between the layers of the transverse mesocolon, in close relation to the transverse colon; they are best developed in the neighborhood of the right and left colic flexures. One or two small glands are occasionally seen along the trunk of the right colic artery and others are found in relation to the trunk and branches of the middle colic artery.


Superior mesenteric glands receive afferents from the jejunum, ileum, cecum, vermiform process, and the ascending and transverse parts of the colon; their efferents pass to the preaortic glands.


Inferior mesenteric glands consist of:

  • small glands on the branches of the left colic and sigmoid arteries
  • a group in the sigmoid mesocolon, around the superior hemorrhoidal artery
  • a pararectal group in contact with the muscular coat of the rectum.

They drain the descending iliac and sigmoid parts of the colon and the upper part of the rectum; their efferents pass to the preaortic glands.


Lymphatic Vessels of the Colon

The lymphatic vessels of the ascending and transverse parts of the colon finally end in the mesenteric glands, after traversing the right colic and mesocolic glands. Those of the descending and iliac sigmoid parts of the colon are interrupted by the small glands on the branches of the left colic and sigmoid arteries, and ultimately end in the preaortic glands around the origin of the inferior mesenteric artery.
