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  omphalo-mesenteric)  connects  the  yolk  sac  to  the  primitive  gut.  It  normally  involutes  by  the  ninth  week  of  gestation,  but  persistence  of  all  or  portions  of  this  duct  can  result  in  a  Meckel  diverticulum  or  other  abnormalities  of  the  omphalomesenteric  duct,  such  as  omphalomesenteric  fistula,  omphalomesenteric  cyst,  umbilical  sinus,  or  mesodiverticular  bands.1
