Anatomical Relations
The mesorectum is the fascia encasing the inferior aspect of the rectum that is not covered by peritoneum. Between the fascia and the rectum, there is a large amount of adipose tissue, the superior rectal vessels, lymphatics, and nerve branches from the inferior hypogastric plexus. The mesorectum is attached to the parietal pelvic fascia by three ligaments, the paired lateral ligaments of the rectum and the singular posterior ligament, which is referred to as the rectosacral fascia (Standring, 2016).
