Describe two major differences btw UC and CD
UC:
- Involves only mucosa/submucosa
- Involves rectum and is continuous
CD:
- Transmural
- Involves skip lesions through out GI tract (70% involve terminal ileum)
Which IBD has creeping fat, mucosal thickening, and potential for Vit. B12 deficiency?
Crohn’s
Which IBD is associated with granulomas?
Crohn’s
Which IBD has potential for fistulas, abscesses, and strictures?
Crohn’s
Which IBD presents with hematochezia?
UC
The ulcers are what is producing the bleeding!
What is tenesmus? Associated with which IBD?
Tenesmus = pain and urgency to move bowels, very frequently (20 x a day to produce bloody mucosy diarrhea)

Serology!
ASCA- Crohn
pANCA- UC
ASCA associated with…
Crohn
pANCA associated with..
Ulcerative colitis
What is role of surgery in ulcerative colitis?
It is curative
What is the role of surgery in Crohn Disease?
NOT CURATIVE!
Just decreases risk for complications
