Ulcerative colitis
What is UC?
An inflammatory bowel disease where the mucosal surface of the colon is inflamed
Where does UC most often occur
in the rectosigmoid areas
May involve entire colon
UC is characterized by what
bloody and purulent diarrhea
UC results in what changes to the intestinal wall
Friability, erosion and bleeding of the mucosal wall.
What is the only “cure” for UC?
A total colectomy (not first treatment option)
Who is most at risk for diverticulitis
obese patients
How do some patient present with divertic
Bleeding not associated with pain or discomfort
What do you see when diverticula become inflamed?
Usual s/s of infection (fever, chills, tachy)
Typical presentation of divertic
Localized pain and tenderness of the LLQ
Anorexia, nausea, vomiting
Why would you do a CT scan in a divertic patient
to rule out GYN etiologies (like cysts or tumors) as well as bowel pathology (abdominal abcesses)
What is the best management for divertic
a high-fiber diet
What is C. diff
a bacterial infection of the large intestine
Where is c.diff found
in water, air, soil, processed foods, feces
Symptoms of c. diff.
-profuse, watery, mucoid diarrhea
- may be asymptomatic
Risk factors for c. diff
-Working in healthcare facility
-Long duration hospitalization
-Long-term use of antibiotics that affects normal -GI flora
-Long-term use of medications that reduce GI acidity
-Consumption of contaminated food or water

-Strong foul odor
-acute abdomen secondary to toxic megacolon with perf.
-fever
-abdominal distention
-nausea/vomiting/dehydration requiring hospitalization
-blood or pus in stools (very severe)
Diagnostic tests for C. diff
-CBC: elevated WBC
-ELISA: detects toxins
-Cell cytotoxicity assay: identifies effects of bacterial toxins on human cells
-polymerase chain reaction: detects bacterial genes
-endoscopy: pseudomembranes that suggest c-diff infection
C. Diff treatment
-metronidazole
-probiotics
-colectomy in severe cases
-maintain fluids
