What to expect during your colonoscopy

A colonoscopy is a procedure in which your physician will insert a thin, flexible tube with a light and a camera on it into your rectum and run this camera the entire length of your colon, looking for polyps. Your physician will then remove any polyps so they can never turn into a cancer.

This procedure is done with the help of medication to make you very sleepy and very comfortable. Contrary to popular belief, it is not a painful procedure thanks to the medications that we use.

Preparing for colonoscopy

To prepare for this colonoscopy, we will need to clean all the stool out of your colon. To be frank, we know what stool looks like. We need to know what you look like. The best chance for us to find small polyps is for you to be very well cleaned out.

This clean-out begins the day before your colonoscopy, at home. You will begin by drinking clear liquids the entire day before the procedure, followed by a liquid medication the evening before the procedure. This medication will give you diarrhea, but will clean you out and give us the best chance of finding any small polyps and then reducing your chance of those small polyps of ever turning into a cancer.

Anyone 50 or older should have a colonoscopy.

Like most cancers, early detection is the best defense and can improve outcomes dramatically. That’s why the American Cancer Society recommends regular colonoscopies for all men and women, age 50 and older, whether or not you have any symptoms. Colon screenings are designed to detect polyps and colon cancer in its earliest stages, when it’s most treatable.

Colorectal screening is an outpatient procedure.

Colon screening or Colonoscopy is an examination of the entire length of the colon using a small camera attached to a flexible tube. Polyps usually can be removed during colonoscopy and tested.

Colon Screening is offered by Good Samaritan Medical Group at CHI Health Good Samaritan.
