Hinchey’s Classification of Diverticulosis (developed by EJ Hinchey):

Clinical staging by Hinchey’s classification is geared toward choosing the proper surgical procedure when diverticulitis is complicated, as follows:

Stage I disease - Small or confined pericolic or mesenteric abscess

Stage II disease - Large abscess, often confined to the pelvis

Stage III disease - Perforated diverticulitis causing generalized purulent peritonitis

Stage IV disease - Rupture of diverticula into the peritoneal cavity with fecal contamination causing generalized fecal peritonitis
