Meckel’s #diverticulum is the most common congenital defect of the GI tract and is a result of incomplete obliteration of the vitelline duct of the umbilical cord. When present, Meckel’s diverticulum arises from the antimesenteric surface of the ileum approximately 40 cm from the ileocecal valve in infants and approximately 50 cm from the valve in adults; it may be less than 15 cm or as much as 167 cm from the valve (Fig. 10.5). Not less than 2 m of ileum should be inspected to ascertain that a diverticulum has not been overlooked. The diverticulum may be as short as 1 cm or as long as 26 cm. In 75% of individuals, the diverticulum will be <5 cm; the rest will be longer.
