Historic Background Ernst Graser, Head of Surgery in Erlangen, in 1899: Herniation of inner wall segments of the colon have been called 'colon diverticula' since his publication First accurately described the clinical entity of inflamed diverticula in the sigmoid colon He named this phenomenon 'peri-diverticulitis' Graser E. Ueber multiple falsche Darmdivertikel in der Flexura sigmoidea. Münch Med Wochenschr 1899; 22: 721-723
Diverticula Technically 'Pseudo-diverticula' as not involving all layers of colon wall (as opposed to 'true' diverticula -> all layers) Graser E. Ueber multiple falsche Darmdivertikel in der Flexura sigmoidea. Münch Med Wochenschr 1899; 22: 721-723
Prevalence today Very common True prevalence difficult to define (most patients remain asymptomatic) Rule of thumb: People who have diverticula in their colon: 5% in <40 year-olds 65% in >65 year-olds In Western countries: majority in sigmoid colon In Asian populations: more frequent in caecum Jun, S. and Stollman, N. (2002) Epidemiology of diverticular disease. Best Practice & Research in Clinical Gastroenterology 16(4), 529-542
Terminology Diverticulosis Denotes the presence of diverticula in the colonic wall, asymptomatic Diverticular disease Diverticula have become clinically apparent with symptoms ('disease' indicating ill health) Diverticulitis Diverticula with superadded inflammation involving bowel wall and/or pericolic fat tissue Köhler L, Sauerland S, Neugebauer E.

Surg Endosc 1999; 13: 430-6
Terminology 'Diverticular disease' not consistently defined ICD-10: Diverticular disease of intestine includes (K57) Diverticulitis Diverticulosis Diverticulum excludes congenital diverticulum of intestine diverticulum of appendix International Classification of Diseases: http://www.who.int/classifications/icd/en
Clinical Classification Diverticular disease classified into: symptomatic uncomplicated disease recurrent symptomatic disease complicated disease Köhler L, Sauerland S, Neugebauer E. Diagnosis and treatment of diverticular disease: results of a consensus development conference. The Scientific Committee of the European Association for Endoscopic Surgery. Surg Endosc 1999; 13: 430-6
Clinical Classification Complicated diverticular disease Köhler L, Sauerland S, Neugebauer E. Diagnosis and treatment of diverticular disease: results of a consensus development conference. The Scientific Committee of the European Association for Endoscopic Surgery. Surg Endosc 1999; 13: 430-6
Hinchey classification Classification Describes severity of inflammation in perforated diverticulitis Used to guide surgical management Advocated by E.A.E.S and the American Society of Colon and Rectal Surgeons Not yet validated with regard to prognostic value Hinchey EJ, Schaal PG, Richards GK. Treatment of perforated diverticular disease of the colon. Adv Surg 1978; 12: 85-109
Hinchey Classification Localised Pericolic Abscess (Hinchey Stage I) Large Mesenteric Abscess (Hinchey Stage II) Free Perforation (Hinchey Stage III) Free Perforation Causing Fecal Peritonitis (Hinchey Stage IV)
Hinchey Classification Modified classification as recommended by E.A.E.S consensus conference: Stage I Stage IIA Stage IIB Stage III Stage IV Pericolic abscess Distant abscess amenable to percutaneous drainage Complex abscess associated with/without fistula Generalised purulent peritonitis Fecal peritonitis Köhler L, Sauerland S, Neugebauer E.

Surg Endosc 1999; 13: 430-6

Summary Diverticulosis: asymptomatic diverticula in colonic wall, whether they are 'true'/'pseudo' or left/right sided is not defined Diverticulitis: inflammatory complication of diverticulosis Diverticular Disease: E.A.E.S consensus: symptomatic diverticulosis ICD 10: umbrella term for colonic diverticula Hinchey Classification: for perforated diverticulitis, accepted tool for planning surgical intervention Severity: APACHE, MPI
