ABSTRACT
The omphalomesenteric duct or the vitelline duct is a long narrow tube that joins the yolk sac to the digestive tube in the developing human embryo. This duct undergoes complete obliteration during the seventh week in most cases. However, in the rare circumstances where there is incomplete obliteration, omphalomesenteric remnants will be the result, which may be apparent in the newborn infant.1
