A Meckel's diverticulum, a true congenital diverticulum, is a small bulge in the small intestine present at birth. It is a vestigial remnant of the omphalomesenteric duct (also called the vitelline duct or yolk stalk), and is the most frequent malformation of the gastrointestinal tract. It is present in approximately 2% of the population,^[1] with males more frequently experiencing symptoms.
