Back-to-back Endoscopy Versus Single-pass Endoscopy and Chromoendoscopy in IBD Surveillance

Using HD white light, the entire colon is examined for dysplasia and other abnormalities after the caecum is reached, with a second segmental inspection after the first examination in the same session.The colonoscope has a high-definition camera and processor. All images are displayed on a high definition monitor for optimal resolution.

After introduction of the endoscope into the colon a dye (methylene blue or indigo carmine) will be sprayed through a catheter positioned into the biopsy channel. Per segment, the entire colon is dyed, inspected, and lesions are removed. Equipment is similar to the other two interventions.
