ABSTRACT

For centuries, the mesentery and associated peritoneal lining have been regarded as structurally complex. In 1885, Sir Frederick Treves provided the first comprehensive description of both, emphasizing that while some mesenteric regions persisted in adulthood, others regressed and were lost [1]. For example, the small intestinal mesentery, transverse, and sigmoid mesocolon were consistently identifiable in adults, while the right and left mesocolon were identifiable in a minority only.
