Colonoscopy
The Gold Standard
Detect Colorectal Cancer
By providing a complete view of the colon, colonoscopy sets itself apart as the most sensitive and effective screening test for colorectal cancer.
Prevent Colorectal Cancer
A high-quality colonoscopy makes it possible to prevent cancer from ever forming by identifying and removing precancerous polyps.
10 Year Screening Interval
After a normal colonoscopy, patients at average risk don't need another screening exam for 10 years.
Preparation and Procedure
Dietary Requirements
The day before your procedure, follow a clear liquid diet. This includes Jello, broth, coffee, tea, and any other liquids that are clear and see-through. Depending on your medical history, you may be instructed to hold certain medications in the days leading up to your procedure as well.
Bowel Preparation
Bowel preparation starts the evening before the procedure. Available options include both prescription and over-the-counter products, as well as liquids or pills. Typically, the preparation involves drinking 1-4 liters of liquid laxatives along with water or other clear liquids. During this process, stay near a restroom. A split-dose prep is often recommended, where part of the prep is taken the evening before and the rest is completed the morning before your procedure. Once you have finished the prep, you can usually continue to enjoy clear liquids until about 2 hours before your appointment.
Procedure Day
When you arrive for your appointment, you’ll change into a comfortable gown, and a nurse will place a small IV in your arm. Your doctor will meet with you to discuss the procedure and answer any questions you may have. Once ready, you’ll be taken to the procedure room, where you’ll receive light sedation to help you relax. The procedure itself typically lasts 20-40 minutes. Afterward, you’ll be brought to the recovery area to rest and wake up before heading home to enjoy some well-deserved food and relaxation.
Risks of Colonoscopy
All procedures carry some level of risk, including those related to anesthesia and the procedure itself. Colonoscopy, however is widely regarded as safe when performed by a high-quality endoscopist. Reported rates of severe complications include:
- Severe Bleeding - less than 1-3.5/1000 procedures
- Perforation (hole in the colon) - less than 1/1000 procedures
- Injury to other abdominal organs - less than 1/30,000-50,000 Procedures
- Death - less than 3/100,000 procedures
- Adverse sedation events - less than 1/1000 procedures
