What is chromoendoscopy during colonoscopy and how does it help diagnose ulcerative colitis?

ANSWER

To diagnose ulcerative colitis, your doctor will look at your whole colon by doing colonoscopy. He may spray a blue dye inside your colon during a colonoscopy. This is called chromoendoscopy, and it lets him see which parts are affected by ulcerative colitis (UC).
