Colonoscopy Q&A

What is a colonoscopy?

Colonoscopy is a procedure that provides a detailed view of the inside of your colon. Dr. Paonessa uses a long, flexible tube with a miniaturized camera on the end called a colonoscope to carry out the procedure.

The colonoscope goes into your rectum and around the entire length of your colon (large bowel). The camera sends back images of the lining of your colon, so Dr. Paonessa can see if there are any signs of disease. She can also carry out polyp removal if you have any polyps growing in your colon.

Colonoscopy is a safe and reliable procedure that has complication rates below 1%. Dr. Paonessa is a highly-skilled endoscopist who routinely performs screening and diagnostic colonoscopies with minimal or no discomfort for patients.


Why might I need a colonoscopy?

You might need a colonoscopy if you have symptoms that could indicate a problem in your colon. These symptoms include:

  • Rectal bleeding
  • Changes in bowel habits
  • Bloody diarrhea
  • Abdominal or rectal pain

These symptoms can occur in many conditions, some of which, like hemorrhoids, are non-life threatening. Other causes can be more serious, like inflammatory bowel disease (IBD) and colorectal cancer.

Colorectal cancer develops from a polyp (adenoma), a small growth in your bowel. Most polyps are harmless, but sometimes they become cancerous (carcinoma) and, in time, can spread to other parts of your body. Removing them before they change into malignant tumors (cancer) is the best way to prevent colorectal cancer.


What is a screening colonoscopy?

It’s a good idea to undergo a screening colonoscopy to check for the early signs of colorectal cancer (polyps) before symptoms develop. Unfortunately, the early stages of colorectal cancer don’t cause any physical signs or symptoms, so by the time you’re experiencing symptoms, the cancer is likely to be at a late or advanced stage.

Attending a screening colonoscopy at regular intervals is the best way to prevent colorectal cancer. Dr. Paonessa can review the guidelines for screening colonoscopy based upon your age, medical history, and family history, and advise you how often you need to have a screening colonoscopy.

What happens during colonoscopy?

Colonoscopy is a safe, painless procedure for which you just need light sedation. Before your colonoscopy at Paonessa Colon & Rectal Surgery, PC, you take an oral bowel cleanser that clears out your colon. This ensures there’s nothing to block the passage of the colonoscope or hide the lining of your colon.

Dr. Paonessa inserts the colonoscope into your rectum and looks at the images of your colon on a monitor. She can remove any polyps and take biopsies of any growths or tumors. She can also harvest tissue samples to test for conditions like ulcerative colitis.

You can go back to work the day after your colonoscopy. Patients often awake after the procedure without realizing it’s over because it’s so easy and painless.
