Colonoscopy

What is a Colonoscopy?

A colonoscopy is a test in which a gastroenterologist looks directly at the lining of the large intestine (or colon) using a small, flexible camera. Colonoscopies are most commonly used to screen for colorectal cancer.

This test can also be used to identify or treat:

Colon polyps
Tumors
Ulceration
Redness or swelling (inflammation)
Pouches (diverticula) along the colon wall
Narrowed areas (strictures) of the colon
Any objects that might be in the colon

During a colonoscopy, your provider might remove tissue or abnormal growths, called polyps.

UR Medicine's Approach

We offer state-of-the-art services provided by nationally known physicians with the most experience and training in the Rochester region. At UR Medicine, we offer standard screening colonoscopies as well as colonoscopies for those who are considered high-risk.

Your provider may recommend a colonoscopy or a sigmoidoscopy, which examines only the lower part of your colon whereas a colonoscopy examines the entire colon. Like a colonoscopy, a sigmoidoscopy uses a thin, flexible tube and can be used for biopsies, screening for colorectal cancer, or removing polyps or hemorrhoids.

Colonoscopies can be used to diagnose and even treat certain conditions. Screening is recommended for adults every 10 years starting at age 45, but you may be eligible for early screening if you have a family history of colorectal cancer or certain medical conditions.

Your provider may suggest a colonoscopy if you:

Have a family history of colorectal cancer
Experience symptoms such as chronic diarrhea, bleeding, or pain with bowel movements
Are at an increased risk for colorectal cancer
Have certain conditions, such as inflammatory bowel disease, including Crohn’s disease or ulcerative colitis

A narrow flexible tube, mounted with a camera and light, is inserted into the lowest part of the small intestine above the colon. You may be fully or partially sedated. As the camera makes its way through your colon, your provider is looking for any abnormalities. They’ll even get a second look as the camera exits your colon.

Tiny tissue samples, called biopsies, may be taken during the test. Your provider can also remove polyps at this time.

Colonoscopies can take as little as 15 minutes, with most ranging from 20 to 40 minutes.

After the test is over, you’ll recover in a hospital room for about 45 to 60 minutes.

The key to a successful colonoscopy is following your preparation instructions. Your UR Medicine provider will walk you through them step-by-step. Colonoscopy prep usually includes following a special diet and taking a powerful laxative in the days leading up to the test.
