Slide 1 :

Case History Male patient, ° 1977 1995 : Hyperthyroidism 1996 : PSC 2003 : Ulcerative colitis 2006 : surveillance colonoscopy; pre-liver transplant Multiple biopsies from different segments 2 area’s : low-grade dysplasia – flat lesions

Slide 2 :

Geboes K, Colombel JF, Greenstein A, Jewell D, Sandborn W, Vatn M, Warren B, Riddell RH. On behalf of the IOIBD Pathology task force Indeterminate colitis : A review of the concept – What’s in a name? Inflamm Bowel Dis 2008 in press

Slide 3 :

Introduction : Case History Colectomy given the associated liver disease and planned liver transplantation Adenocarcinoma T2 Colitis with Rectal sparing Patchy lesions Variable architectural abnormalities of the mucosa Thickening – separation of muscularis mucosae Mild active, mild chronic inflammation

Slide 4 :

Indeterminate Colitis (IC) Colitis – Inflammatory Bowel disease unclassified (IBDU) Problems – Definitions – Do You use IC? (BSG audit 2006)

Slide 5 :

Indeterminate Colitis (IC) There are many different definitions of this condition

Slide 6 :

Indeterminate Colitis - Definitions Definitions used in Pathology Colectomy specimens showing overlapping features of Crohn’s disease and ulcerative colitis or data are insufficient to make a decision.(Kent e.a. 1970) Colectomy specimens showing overlapping features of both Crohn’s disease and ulcerative colitis.(Price et al 1978) Colectomy specimens in whom a clear pathologic distinction between ulcerative colitis and Crohn’s disease is impossible (because of failure to recognize or accept certain criteria as indicative of Crohn’s disease or because of the absence of adequate clinical and radiographic material or because of inadequate biopsy material).(Odze et al 2004) Inability to make a confident diagnosis of the pattern of colitis despite examination of an adequate surgical resecate or adequate mucosal biopsy series from the colon and rectum.(Price et al 1996)

Slide 7 :

Indeterminate Colitis - Definitions Definitions used in Pediatrics A history of chronic colitis compatible with both the diagnosis of CD or UC.(Auvin et al 2005) Colitis that can not definitively be declared as CD or UC based on clinical history, physical examination, endoscopic appearance, histologic findings and radiologic studies.(Heyman et al 2005) Endoscopy and histopathology are either inconclusive or divergent with regard to the diagnosis of UC or CD.(Bentsen et al 2002) Exclusive inflammation of the large bowel and neither endoscopic nor histologic findings typical for CD or UC.(Pozler et al 2006)

Slide 8 :

Indeterminate Colitis - Definitions Definitions used in Pediatrics Indeterminate colitis can only be diagnosed after a full diagnostic work-up. This must include colonoscopy with intubation of the terminal ileum, upper gastrointestinal endoscopy and small bowel follow through. Diagnosis of indeterminate colitis is suggested by histology showing acute and chronic inflammation with architectural changes confined to the colon, absence of abnormalities suggesting lymphocytic or allergic colitis, or CD, a normal small bowel follow through or enteroclysis and no definite classification of CD or UC possible with histology.(2005)

Slide 9 :

Indeterminate Colitis - Definitions Definitions used by Gastroenterologists – Surgeons - Epidemiologists A disease with “clear” evidence of inflammatory bowel disease but insufficient evidence to make a definite diagnosis of either UC or CD.(Ekbom 2000) Diagnosis based on a double-contrast barium enema examination, endoscopy, and histopathology being conclusive for a diagnosis of IBD but inconclusive for a diagnosis of either definite UC or CD.(Matsui et al 2003) Patients who have the clinical and macroscopic features of either CD or UC, both pre- and per-operatively. The histology remains indeterminate both pre- and post(per)operatively (includes mucosal biopsies and colectomy specimens).(Kangas et al 1994)

Slide 10 :

Indeterminate Colitis - Definitions Definitions used by Gastroenterologists – Surgeons - Epidemiologists Patients with mucosal ulcerative colitis with histologic features of CD such as skip lesions, transmural inflammation, granulomata or mucin depletion but no clinical or radiological evidence of CD.(Pishori et al 2004) Colitis, for which endoscopic, histologic and radiologic criteria fail to discriminate between UC and CD of the colon.(Burakoff 2004) Colitis for which there is no identifiable cause and with clinical features of both UC and CD.

Slide 11 :

Recommendation Proposal for classificationbased on Montreal WCOG working party 2005IOIBD 2006 When the diagnosis is based upon evidence including colectomy samples Colitis of known type / etiology (UC, CD, …) Colitis with (some) features of CD (to be specified)* Colitis of uncertain type / etiology – no features of CD (Indeterminate colitis) Colitis not classifiable with the available material When the diagnosis is based upon evidence including mucosal biopsy samples Colitis of known type / etiology (UC, CD etc) Colitis IBD type unclassified (IBDU) Colitis of uncertain etiology (Possible IBD) Colitis non classifiable with the available material * Implications for potential IPAA
