Persistence of the vitelline duct can lead to which of the following?A. Colonic diverticulum
During the third trimester of pregnancy, the vitelline duct regresses. Persistence of the vitelline duct remnant on the ileal border results in a Meckel diverticulum. Complete failure of the vitelline duct to regress results in a vitelline duct fistula which is associated with drainage of small intestinal contents from the umbilicus. If both the intestinal and umbilical ends of the vitelline duct regress into fibrous cords, a central vitelline duct (omphalomesenteric duct) cyst may occur.
