Colonoscopy Video Tour: Journey Through a Healthy Colon

ACG Trustee Mark B. Pochapin, MD, FACG, Director, Division of Gastroenterology New York University Langone Medical Center (former Director of The Jay Monahan Center for Gastrointestinal Health), narrates a tour of a patient’s healthy colon during a colonoscopy where he explains why colonoscopy is the preferred method for colorectal cancer screening and why a proper bowel prep prior to the procedure is vital.

What does a colonoscopy show?

During a colonoscopy, a doctor uses a thin, flexible tube with a camera to examine the lining of the entire colon and rectum. The video tour above shows what a healthy colon looks like: smooth, pink tissue with visible blood vessels. Polyps, inflammation and other abnormalities can be seen and, in many cases, removed during the same procedure.

Who should get a screening colonoscopy?

• Adults at average risk should begin colorectal cancer screening at age 45.
• People with a family history of colon cancer or polyps may need to start earlier.
• Anyone with rectal bleeding, a change in bowel habits or unexplained anemia should talk with a doctor, regardless of age.

How to prepare

A clean colon is essential for a clear view. Your doctor will give you instructions for a bowel preparation, which usually includes a special diet the day before and a laxative solution. Following the instructions closely helps ensure an accurate exam.

What to expect afterward

Most patients receive sedation and rest briefly afterward. Mild bloating or gas is common, and most people return to their normal routine the next day. Your doctor will review the findings and any recommended follow-up with you.
