Hinchey classification of acute diverticulitis

Edward John Hinchey et al. 3 proposed a classification for acute diverticulitis, that has been variously adapted, and is useful not only in academia but also in outlining successive stages of severity.


  • stage Ia: phlegmon
  • stage Ib: diverticulitis with pericolic or mesenteric abscess
  • stage II: diverticulitis with walled off pelvic abscess
  • stage III: diverticulitis with generalized purulent peritonitis
  • stage IV: diverticulitis with generalized fecal peritonitis
