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
