Colonoscopy Explained

A colonoscopy enables your physician to carefully examine the large intestine, also known as the colon. This procedure is typically utilized to screen for colon polyps and colon cancer; it is also used to explain symptoms which may include rectal bleeding and diarrhea. The instrument used to perform the procedure is called a colonoscope, which is a flexible tube that is about as thick as your little finger. A light source at the tip of the device illuminates a camera that is used to project images onto a video screen.

After you are sedated, the colonoscope is inserted into your rectum and advanced toward the entrance of the colon. During the colonoscopy, polyps can be removed and tissue samples – called biopsies – can be obtained. The procedure takes only about 15-20 minutes to perform.

Will I be comfortable during the colonoscopy?

Yes, your comfort during the colonoscopy is a very high priority. You should not feel any pain during the colonoscopy. We understand that one of the biggest reasons that patients do not get their screening colonoscopy is because of the fear of pain during the colonoscopy.

The sedation medication that we utilize is known as Propofol. Propofol will guarantee that you are appropriately sedated during the procedure. Unlike traditional methods of sedation, Propofol ensures that you will not “wake up” in the middle of the procedure which may cause you unnecessary pain or discomfort.

Prior to the colonoscopy, a colon prep or cleansing solution is administered to clear the colon of all fecal matter to allow proper visualization of the lining. A colonoscopy is considered the quintessential test when screening for colon polyps and colon cancer.
