Chromoendoscopy Steps

Chromoendoscopy 2

Patients with ulcerative colitis and Crohn’s colitis are at increased risk for colorectal cancer and undergo routine surveillance colonoscopy to detect dysplasia. Chromoendoscopy (CE) involves spraying a dye to the colon mucosa; to provide contrast enhancement and more easily identify dysplastic lesions. In multiple studies, it has been superior to random biopsies in identifying dysplasia in inflammatory bowel disease (IBD) patients. The current SCENIC guidelines and professional societies have endorsed it as the preferred method for surveillance in patients with IBD.

The following educational tools consist of an atlas, videos and a consensus statement about chromoendoscopy. Reviewing the following material will help you get started. Please fill out the survey if you would be interested in participating in a Chromoendoscopy CME course.

Prior to starting chromoendoscopy you should:

  1. Review Atlas of Endoscopic Pictures of Chromoendoscopy and How to Get Started (pdf)
  2. Review An Atlas of the Nonpolypoid Colorectal Neoplasms in Inflammatory Bowel Disease (pdf)
  3. Review educational videos describing the procedures
  4. Review SCENIC consensus statment about chromoendoscopy
  5. Perform your first five cases with someone who routinely performs chromoendoscopy
  6. Please fill out a survey evaluating the above educational materials.
