Where Is the Omphalomesenteric Duct Located?

(Vitelline duct labeled on bottom image.) In the human embryo, the vitelline duct, also known as the vitellointestinal duct, the yolk stalk, the omphaloenteric duct, or the omphalomesenteric duct, is a long narrow tube that joins the yolk sac to the midgut lumen of the developing fetus.

What is the omphalomesenteric duct?

The omphalomesenteric duct is the embryonic structure connecting the primary yolk sac to the embryonic midgut that normally becomes a thin fibrous band, which eventually disintegrates and is absorbed spontaneously at the 5^th-10^th wk of gestation[5,6].

What is the function of the omphalomesenteric duct?

The omphalomesenteric (vitelline) duct is a normal component of fetal development. It connects the fetal intestine to the yolk sac. When these structures persist in a newborn, they are called omphalomesenteric duct remnants.
