Colonoscopy Q & A

What is a colonoscopy?

A safe and generally routine procedure whereby your gastroenterologist can view the lining of your colon. Though some people may dread the dread this procedure, Dr. Chatoo makes your screening exam comfortable and stress-free. The patient is first anesthetized and will either not remember the procedure at all nor will they be uncomfortable during the procedure. Dr. Chattoo carefully inserts a small video endoscope through the rectum and advances it to visualize the interior walls of the colon along its entire length. If polyps are discovered, the physician will remove them as he removes the endoscope.

Why do I need a colonoscopy? 

Colorectal cancer (CRC) is often caught early when a person has a colonoscopy. Almost 90% of CRC cases can be prevented by safely removing pre-cancerous polyps are discovered and removed during this screening exam. This simple outpatient procedure that costs only a few hours of your time may save your life. A colonoscopy exam also may enable Dr. Chattoo to diagnose other gastrointestinal disorders you may have been unaware of. A colonoscopy is an easy, effective way for Dr. Chattoo to diagnose any stomach or intestinal problems. Other benefits of this procedure include:

During  - You will be sedated throughout the colonoscopy process and therefore should experience no pain. Dr. Chattoo will speak with you shortly after you wake up and go over your results. He will provide you with a written report to take home with you.  

After - After the procedure, the patient is monitored for 30 to 60 minutes in the recovery room. During this time, the anesthetic will wear off, but some grogginess may persist. Because the effects of sedation will make it unsafe for you to drive or return home alone, be sure and arrange for someone to assist you. The patient generally will be back to normal by the following day.
