WHAT IS A COLONOSCOPY?
Colonoscopy is a safe, effective method for examining the inside lining of the colon and rectum. A long flexible tube is used and allows the biopsy and removal of most polyps. This is done under a light anesthetic. There is minimal, if any, discomfort and people return to normal activities the next day.
WHO SHOULD HAVE A COLONOSCOPY?
Everyone over the age of 50. If there is a family history of colon cancer, a personal history of other cancers, or other specific diseases, then a colonoscopy at 40 years old may be warranted.
HOW IS A COLONOSCOPY PERFORMED?
The colon must be cleaned of stool to see the colon wall. This is done the day before the procedure and is the worst part of the whole process.
The procedure is done under a “twilight sleep.” The colonoscope is inserted into the rectum and then advanced the entire length of the colon. If needed, biopsies or removal of polyps are done. The exam last about 30-45 minutes. Most people do not remember any part of the procedure.
WHAT ARE THE BENEFITS OF COLONOSCOPY?
Detection and removal of pre-cancerous polyps. This is an important part of preventing colon cancer.
WHAT ARE THE RISKS OF COLONSCOPY?
Colonoscopy is a very safe procedure. Complications (bleeding, a tear or hole in the colon wall, anesthesia risks, failure to detect a polyp) occur less than 1% of the time.
