Colonoscopy is a procedure that uses a long, flexible, narrow tube with a light and tiny camera on one end to look inside your rectum and colon (called a colonoscope).
Colonoscopy can show irritated or swollen tissue, ulcers, polyps, and cancer. A trained specialist performs this procedure. The colonoscope has a tool that can remove polyps. A trained specialist typically removes polyps that he or she finds during colonoscopy. A pathologist will check the polyps for cancer.
Virtual colonoscopy uses computerized tomography (CT) to look inside your rectum and colon. CT machines use a combination of x-rays and computer technology to create images. Virtual colonoscopy can show irritated or swollen tissue, ulcers, and polyps. Doctors can't remove polyps during virtual colonoscopy. If virtual colonoscopy shows a polyp, doctors will most often recommend a colonoscopy to confirm the diagnosis and remove the polyp.
A lower GI series is an x-ray that doctors use to look at your large intestine. For the procedure, you'll be asked to lie on a table while a health care professional inserts a flexible tube into your anus. Next, the health care professional fills your large intestine with barium, which makes polyps show up more clearly on x-rays. Doctors most often use lower GI series in combination with flexible sigmoidoscopy, because flexible sigmoidoscopy doesn't examine the entire colon.
Doctors treat colon polyps by removing them.
In most cases, the doctor uses special tools to remove colon polyps during colonoscopy or flexible sigmoidoscopy. During some procedures, doctors may use a special method they call endoscopic mucosal resection to remove some larger polyps. In endoscopic mucosal resection, doctors inject a solution underneath the polyp or apply suction to lift the polyp away from the healthy colon tissue. Doctors then remove the polyp. After the doctor removes polyps, he or she sends them for testing. A pathologist will check the polyps for cancer. Doctors can remove almost all polyps without surgery.
