Quick Facts
Location: Mesorectum with the superior anorectal artery.
Drainage: Recto-sigmoid region and upper part of rectum.
Direction of Flow: Inferior mesenteric lymph nodes > preaortic and lateral aortic lymph nodes > intestinal trunk and left lumbar trunk > cisterna chyli > thoracic duct.

Description: (Location & Drainage)
The superior rectal lymph nodes are associated with the superior rectal artery in the mesorectum. They are responsible for the drainage of lymph from the recto-sigmoid region and the upper part of the rectum. They are also interconnected with the pararectal lymph nodes, which drain lymph from the inferior two thirds of the rectum.
The superior rectal lymph nodes carry lymph to the inferior mesenteric lymph nodes. From here, the lymph reaches the cisterna chyli via two routes, firstly, the preaortic lymph nodes and the intestinal trunk, and secondly, the lateral aortic nodes and the left lumbar trunk.
