A colonoscopy is an outpatient procedure that gastroenterologists use to examine the lining of the colon. A colonoscopy is also used to screen for colorectal cancer or polyps.

At Valley, our gastroenterologists perform colonoscopies in our state-of-the-art endoscopy suite using the latest technology. Our team also offers a Fast-Track Screening Colonoscopy program for low-risk patients, to make the process of scheduling and getting a colonoscopy easier and more affordable.

What to Expect

Preparing for a colonoscopy

Colonoscopies are generally well-tolerated by patients. On the day before the procedure, your doctor will recommend you follow some dietary restrictions and use a colon cleansing method (drinking a cleansing solution or taking oral laxatives). Your colon must be completely clean for the test to be accurate. Before your appointment, check with your doctor about any medications you are taking, including aspirin, anti-coagulants, arthritis medications, or iron products. Also let your doctor know if you have any allergies to medications.

During your colonoscopy

You should plan to be here for two to three hours for preparation, the procedure and recovery. Because your gastroenterologist will give you sedation for your procedure, you cannot drive for 24 hours after the procedure.

While you are lying on your side, your doctor will insert a thin flexible tube into your anus and slowly advance it into your rectum and colon. The tube contains fiberoptics that will enable your doctor to view the inside of your digestive tract in color on a television monitor. During a colonoscopy, your doctor will look for polyps, internal bleeding or other abnormalities. Using special instruments attached to the scope, he/she can remove polyps, take tissue samples for a biopsy, or stop internal bleeding.

After your colonoscopy

A nurse will monitor you until the sedation wears off. You may have some cramping or bloating afterward. You must have someone drive you home. You should be able to eat when you return home. If your doctor removed tissue for a biopsy or any polyps, they will notify you with the results.
