Correct Answer » C Explanation |
 |
-
The key clue in the question is:
“Multiple fistulas”
-
Multiple fistulas are characteristic of:
Crohn’s disease
because Crohn’s disease causes:
- Transmural inflammation
- Deep fissures and sinus tracts
- Perianal fistulas
- Bloody diarrhea can occur in Crohn’s disease, although it is more common in ulcerative colitis.
Why Other Options are Incorrect
A. Intestinal tuberculosis
- May produce fistulas, but usually associated with:
- Fever
- Weight loss
- Ileocaecal involvement
- Multiple fistulas are more typical of Crohn’s disease.
B. Ulcerative colitis
- Bloody diarrhea is common.
-
However:
Fistulas are rare
because inflammation is limited to mucosa and submucosa.
D. Typhoid
- Causes fever and intestinal ulcers.
- Does not cause chronic fistulizing bowel disease.
