How a Colorectal Surgeon Detects Polyps During Colonoscopy

A colonoscopy is widely regarded as the gold standard for colon cancer prevention, and for good reason. It is one of the few medical screenings that can actually prevent cancer from developing. At the Northwest Center for Colorectal Health in Portland, OR, Dr. Scott M. Browning, MD, Dr. Jeffrey V. Manchio, MD, and Dr. Richard U. Kalu, MD, utilize advanced techniques to identify and remove precancerous polyps before they have the chance to become a threat.

What is a Polyp?

Colon polyps are small growths that develop on the inner lining of the colon or rectum. While most polyps are benign, certain types, known as adenomas, can eventually transform into colorectal cancer over several years. Because polyps rarely cause symptoms in their early stages, visual detection during a colonoscopy is the only way to find them.

The Detection Process

During the procedure, your surgeon uses a colonoscope, a thin, flexible tube equipped with a high-definition camera and a dedicated light source. As the scope is carefully advanced through the colon and then slowly withdrawn, the surgeon performs a meticulous inspection of the intestinal wall.

High-Definition Imaging We utilize state-of-the-art video technology that provides a clear view of the colonic mucosa. This high resolution allows us to see subtle changes in the texture or color of the lining, helping us spot even flat or "sessile" polyps that might be missed with older equipment.

Meticulous Withdrawal and Mucosal Inspection The most critical part of the exam occurs during the withdrawal of the scope. Our Portland, OR, surgeons take significant time to "look behind" the many folds and crevices of the colon. By gently inflating the colon with air or carbon dioxide, we can smooth out the lining to ensure no growth is hidden from view.

Chromoendoscopy and Light Filtering In some cases, we use specialized light filtering or harmless dyes to enhance the contrast of the tissue. This makes the unique vascular patterns of a polyp stand out against the healthy surrounding tissue, raising the odds we’ll catch even the smallest abnormalities.

Immediate Action: Polypectomy

The true power of the colonoscopy lies in the fact that detection and treatment happen simultaneously. If a polyp is found, your surgeon can remove it immediately using specialized tools passed through the scope. This process, called a polypectomy, is painless and effectively eliminates the risk that the specific polyp will develop into cancer.
