4. 1- Introduction Chronic inflammatory disease extending to several years affecting GI Presents as CD or UC Unknown etiology, environmental, genetics &immunological Uncontrolled immune response within the intestine Incidence 1 - 2/10000

5. 2-pathogenesis CD Affect any part from mouth to anus Ulcer is deep Cobble stone appearance Complication include granuloma and fistula Has malignant potential Th-1 immune response Most common site: ileal or ileaocolonic 45%, small intestine 35%, colon 20% UC Colon only Ulcer is superficial Crypititis appearance Less probably to develop malignant potential Th-2 immune response Most common site: proctitis or proctosigmoiditis 50%, left sided 35%, pancolitis 20%

10. CD &UC

11. 3- Clinical features CD Depends on the site of the lesion Ileocecal: abdominal pain & weight loss Colonic: bleeding, diarrhea, pain related to defection Perianal: tags, fissures, fistula UC Bloody diarrhea & mucus The first attack the most severe one Followed by relapse & remission Minority have chronic unremitting symptoms
