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).
