Colonoscopy of Crohn's Disease

Colonoscopy of Crohn's Disease
Crohn's disease, also termed ileitis, regional enteritis, or granulomatous colitis, is a chronic inflammation of the intestine, often involving the lower section of the small intestine called the ileum. Crohn's disease is relatively rare and can often be controlled with medical management. Around 70% of Crohn's sufferers will require surgery at some point, typically to correct obstruction, abscesses, or perforation. While surgical treatment can alleviate the symptoms it does not cure Crohn's disease.

The timing of colonoscopy in Crohn's disease depends on several factors. Colonoscopy is performed to assess which parts of the lower bowel (rectum, colon and terminal ileum (end of the small bowel)) are affected to:
1) initially make a diagnosis,
2) assess the effectiveness of treatment
3) to assess whether ongoing symptoms such as pain and diarrhoea are due to active Crohn's inflammation in order to guide a change in therapy, or from any complications such as strictures (narrowings) in the bowel.
4) assess if there are changes in the bowel that might increase the risk of bowel cancer. This is usually only done in patients where extensive amounts of the colon is involved. There is a small increase in the chance of developing colon cancer after many years (usually more than 10) of disease in these patients. In this situation, colonoscopy is usually performed yearly from 8 to 10 years since diagnosis.
