Y1 - 2018 N1 - T2 - Rudolph's Pediatrics, 23e AB - An “unusual” diverticulum of the small intestine was first described by Fabricius Hildanus in 1598, but Johannes Meckel wrote the first definitive description of the Meckel diverticulum in 1809. The vitelline (or omphalomesenteric) duct normally involutes by the ninth week of gestation, but persistence of all or portions of this duct can result in a spectrum of abnormalities of the omphalomesenteric duct, such as a fistula, cyst, umbilical sinus, or mesodiverticular bands (Fig. 397-1).
