Colonoscopy

Colonoscopy is a medical procedure used to detect colon-related illnesses or malignancies. It is currently considered to be the "gold standard" for colorectal cancer screening. Colonoscopy is used a both a diagnostic and a therapeutic tool, as small polyps can be removed during the procedure.

One may also need to have a colonoscopy to evaluate the following symptoms:

  • Diarrhea
  • Constipation
  • Rectal bleeding
  • Anemia
  • Unexplained abdominal pain
  • Other intestinal problems

We may recommend a colonoscopy to:

Investigate intestinal signs and symptoms. A colonoscopy can help your doctor explore possible causes of abdominal pain, rectal bleeding, chronic constipation, chronic diarrhea and other intestinal problems.

Screen for colon cancer. If you're age 50 or older and at average risk of colon cancer — you have no colon cancer risk factors other than age — your doctor may recommend a colonoscopy every 10 years to screen for colon cancer. Colonoscopy is one of many options for colon cancer screening. Talk with your doctor about other options.

Look for more polyps. If you have had polyps before, your doctor may recommend a follow-up colonoscopy to look for and remove any additional polyps. This is to reduce your risk for colon cancer.

What happens during colonoscopy

The colonoscopy is performed by a doctor experienced in the procedure and lasts approximately 30-60 minutes. Medications will be administered by an anesthesiologist to ensure maximum comfort during the procedure.

During a colonoscopy, the doctor uses a colonoscope, a long, flexible, tubular instrument about 1/2-inch in diameter that transmits an image of the lining of the colon so the doctor can examine it for any abnormalities. The colonoscope is inserted through the rectum and advanced to the other end of the large intestine.

You will be sedated during the procedure. Anesthesiologist will assure pain-free, comfortable and safe experience
