LAS VEGAS — In this exclusive video perspective from the Crohn’s & Colitis Congress 2019, Tonya Kaltenbach, MD, from the University of California San Francisco and the San Francisco Veteran’s Affairs Medical Center, discusses how using chromoendoscopy can improve colonoscopy screening in patients with inflammatory bowel disease.

“The key things that we think about when we’re surveying our patients is what can give us the highest quality colon examination, the highest protection for them to not develop colon cancer in the future,” she told Healio Gastroenterology and Liver Disease. “Surveying these patients with optimal techniques that are available here today in 2019, includes chromoendoscopy.”

Kaltenbach said the dye improves contrast in the colon helps endoscopists find lesions. Additionally, it helps improve confidence in finding the borders of polyps located during a screening.

Although alternatives to chromoendoscopy have been developed in recent years, Kaltenbach said they have not been able to provide the same efficiency. Although the technique is not perfect, she said it is still beneficial for colonoscopy screening.

“Ultimately, what we hope is that we can lengthen surveillance intervals,” she said. “Because surveillance colonoscopy is a burden for patients to undergo annually. It’s a burden for health care resources and for our own clinics and endoscopy time.”
