The mesenterium, often referred to as the mesentery, is a fold of peritoneum that attaches the intestine to the posterior abdominal wall. It serves a crucial role in anchoring the small and large intestines in place, preventing them from becoming tangled and ensuring their proper positioning within the abdominal cavity. The mesentery is not a single, solid structure but rather a complex arrangement of tissues containing blood vessels, nerves, lymphatics, and adipose tissue. These vital structures pass through the mesentery to supply and drain the intestines.

Historically, the mesentery was viewed as a fragmented structure with no unifying anatomical identity. However, research over the past decade has led to a reclassification, with the mesentery now widely accepted as a continuous anatomical entity. This redefinition has significant implications for understanding intestinal diseases and surgical procedures. The blood supply to the intestines, originating from the superior and inferior mesenteric arteries, runs within the mesentery, highlighting its importance in maintaining intestinal health and function. Disruptions to the mesentery, whether through inflammation, trauma, or congenital abnormalities, can lead to serious complications affecting intestinal viability and function.
