Basic topics of embryology and anatomical contemporary classification of the mesentery and the main differences between the traditional and the new proposal of mesenteric anatomy.
Although recent data have revolutionized the concepts about the mesenteric anatomy, anatomical and embryologic books and publications continue to present classic anatomical descriptions. Thus, our focus will not be on the classical concepts: we will be addressing the proposed new concepts.
Recent data suggest a change in the formerly known anatomical model of mesentery, now proving its continuity and defending his new classification as an organ due to its uniqueness, function and role in disease. The classic concept of mesenteric fragmentation was overcome: it was previously believed that the mesentery of the ascending and descending colon region right and left mesocolon did not exist in the adult due to regression or resorption mechanism.
Today, it is known that the mesentery is a continuous structure from distal to the duodenojejunal flexure to the mesorectal level, including the normal presence of the right and left mesocolon. The classic model of mesenteric embryology was based on the anatomical concept of mesenteric discontinuity. According to this model, the small bowel mesentery, as well as that of the transverse colon and sigmoid, persists into adulthood. However, the right and left mesocolon regress, which would make mesentery discontinuous and fragmented.
Theories were developed to try explain right and left mesenteric involution, but none of them were widely accepted. Despite the mesenteric fragmentation theory, the start and end points for each mesenteric region have never been identified, which corroborates the lack of consistency of this observation.
