IBD- crohns and ulcerative colitis Flashcards
what sites can crohns disease affect?
anywhere from mouth to anus (common in ileum)
what sites can ulcerative colitis affect?
colon and rectum-starts in rectum and can extend upwards through large intestine/colon in continuous manner
what are the differences between chrons and ulcerative colitis?
chrons- discontinuous, affects full thickness of wall, can extend externally (anal fissures, abscesses), causes oedema and cobbled mucosa, narrowed lumen due to oedema
colitis- continuous, affects superficial mucosa, only in colon/rectum. increased vascular supply due to inflammation, causes mucosal ulceration
can chrons affect the oral cavity, if so how?
yes- causes same things seen in gi tract- cobbled mucosa- oedema of lips/mouth-inflammation of face=orofacial glanulomatosis
do you always have GI problems with orofacial granulomatosis?
no- if along side GI chrons= oral chrons disease
what are the symptoms of colitis?
-diarrhoea
-abdominal pain
-rectal bleeding
what are the symptoms of chrons?
same as colitis
+ malabsorption if in small intestine
+ acute pain if blockage of small intestine due to oedema
+ orofacial granulomatosis (cobbled mucosa, facial inflammatory changes, oedema of lips/face/mouth)
how is chrons/colitis investigated?
-faecal samples
-endoscopy- biopsy
-blood tests- inflammatory markers/ anaemia
what is the treatment of chrons/colitis?
nsaids- pain/inflammation
systemic steroids-prednisolone
localised steroids
none steroidal immunosuppressants- dmards-methotrexate
anti TNFa therapy- “biologics” “babs”
surgery- colectomy (colitis only)- relives all symptoms
