The pararectal lymph nodes are lymph nodes that are in contact with the muscular coat of the rectum.

Structure

The pararectal lymph nodes are located on the left and right of the rectum.^[1] Their efferent lymph ducts pass to the pre-aortic lymph nodes.

The pararectal lymph nodes drain the descending iliac and sigmoid parts of the large intestine, and the upper part of the rectum.
