The vitellointestinal duct is a communication between the midgut and the yolk sac of the embryo during the first few weeks of fetal life (fig. 1). Persistence of this duct or of portions of it gives rise to a deformity known as Meckel's diverticulum,1 so called after J. F. Meckel, who was the first to publish an adequate description of the anomaly, in 1812,2 though he had mentioned it in an earlier publication, in 1809.3 According to Lichtenstein,4 the diverticulum was mentioned by Hildanus in 1598.
