How can flexible sigmoidoscopy help in the diagnosis of ulcerative colitis?

ANSWER

Flexible sigmoidoscopy lets a doctor look at the lower part of your colon. He will put a bendable tube into your lower colon. The tube has a small light and camera on the end. Your doctor might also use a small tool to take a piece of the lining of your lower colon. This is called a biopsy. A specialist will look at the sample under a microscope.
