What is a Colonoscopy?

Colonoscopy is the most effective way of examining the lining of the colon and rectum. By using a fiberoptic scope designed to bend and turn with your bowl, the doctor can perform biopsies and remove pre-cancerous polyps.

Here is the Colonoscopy Information PDF for information on the Colonoscopy Procedure.

Does having a Colonoscopy Prevent Colon Cancer?

By removing pre-cancerous polyps, over 90% of colorectal cancers can be prevented. There are however, 2 situations where a colonoscopy may fail to detect or prevent cancer:   (Fortunately they are not common)

  1. A small cancer or polyp “hidden” by either a large fold in the colon, or stool left inside despite the bowel prep.
  2. A fast growing cancer that develops in-between screening exams


How is the Colonoscopy performed?

The exam is performed at the hospital as an outpatient procedure. An intravenous line is placed so that you can be given sedation. After the sedation take effect, the scope is inserted and the entire bowel is checked for abnormalities. If polyps are found, they are removed during the exam and sent to pathology to be analyzed.

Afterword, you will need a driver to take you home. You cannot work the day of the exams, but the following day you may return to your normal schedule.

Can there be complications?

Colonoscopy is the safest when performed by physicians with specialty training, such as Dr. Kolachalam. Possible complications are rare. It is important for you to recognize the early signs of any possible problem.

They can include, but are not limited to;

  1. Heavy bleeding can occur up to 2 weeks after a polyp is removed. This occurs if the “scab” from the polyp site breaks off. If you pass a 1/2 cup or more of blood, call you physician or go to the hospital’s emergency room. Be sure your physician knows you take any blood thinners (COUMADIN, PLAVIX, TICLID, or others)
  2. Perforation may not be evident until the evening after or the day following your exam. If you develop abdominal pain, fever, and chills, or vomiting call immediately. Some perforations can be treated with antibiotics. Others require surgery.
