Chromoendoscopy is a technique that uses dye to detect precancerous tissue growth or lesions in body. Our team uses this technique to screen your intestines for these changes in the tissue of the colon that could become cancer over time. Our doctors are highly trained in this procedure and have been using chromoendoscopy, a relatively new technique, to detect cancer risk in patients for several years.

Why is Chromoendoscopy Performed?

When used by highly trained doctors at specialized centers like ours, this technique appears to have a higher and more accurate detection rate of precancerous tissue in the gastrointestinal tract than other traditional methods.

What to Expect During a Chromoendoscopy

Your doctor may perform the chromoendoscopy as part of a colonoscopic procedure. Colonoscopy is a visual examination of the colon using a thin, flexible tube with a lighted camera at the tip, called a colonoscope. The camera projects magnified images of the colon to a television screen.

During the chromoendoscopy:

  • Your doctor will apply a blue dye solution  to your intestine, using the colonoscope
  • The dye highlights the tissue and stains the normal cells. Cancerous and precancerous areas will not pick up the dye, making it easy for a trained eye to spot these areas.
  • Your doctor can then target abnormal appearing areas and remove tissue for further study (biopsy)
