Hinchey classification of acute diverticulitis

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 1a - phlegmon
  • stage 1b - diverticulitis with pericolic or mesenteric abscess
  • stage 2 - diverticulitis with walled off pelvic abscess
  • stage 3 - diverticulitis with generalised purulent peritonitis
  • stage 4 - diverticulitis with generalised faecal peritonitis
