Physical examination by a doctor includes a gentle inspection of anal region. This usually is sufficed for the diagnosis of Anal fissure where very often the tear is visible.
The location of the fissure points its causation. A fissure that occurs on the side of the anal opening, rather than the back or front, is more likely to be a sign of Crohn's disease.
If the doctor suspects any underlying disorder he may recommend:
- Flexible sigmoidoscopy . A thin, flexible tube with a tiny video camera is inserted into the bottom portion of the colon. This is done if you are younger than age 50.
- Colonoscopy . A flexible tube is inserted into your rectum to inspect the entire colon. This test may be done if you are older than age 50.
