Direct Access Colonoscopy Program

Are you 50 years of age or older and never had a screening colonoscopy? Are you 40 years of age or older with a family history of colon cancer?

Colon cancer is the second leading cause of cancer death. Early detection is the key to prevention. Ask us about scheduling your screening colonoscopy.

What is a Colonoscopy?

A colonoscopy is a procedure that is used to look for colon polyps, colon cancer, diverticula, or other abnormalities. The most common reason people receive a colonoscopy is for colon cancer screening. This is generally recommended for patients over the age of 50 every ten years, if they have no personal or family history of polyps or colon cancer.

Sometimes patients will have other reasons they need a colonoscopy – like a history of colon polyps, a family history of colon cancer, blood in the stool, constipation, or a history of diverticulitis, among others.

This procedure is done in a procedure room with minimal sedation—which reduces your cost if the procedure is not covered at 100% by your insurance carrier as a preventative benefit, or if the colonoscopy is for a medical condition.

Your procedure will be performed by Kristan D. Guenterberg, MD.

Bowel Prep

Once you have been scheduled, the physician’s office will call in a prescription to your pharmacy for your bowel prep which will clean out the colon. There are 2 bowel preps to choose from:


Day of Procedure

You MUST have a designated individual to be your escort. Your escort will need to remain in the facility throughout your procedure and drive you home afterwards. If you do not have an escort, your procedure will be cancelled.

Once you arrive at the center an IV will be placed which will be used to give you medication that will make you sleepy. The exam will take about 30-45 minutes. You will then be observed for a short period of time to make sure you have recovered from the medication. You will then be discharged.

After Your Procedure

You shouldn’t operate any machinery, drive, or make major decisions following your procedure. You can resume your normal diet right after surgery. The doctor will then notify you of the results via a phone call.
