Colonoscopy is a procedure to visualize the inside of the large intestine (colon and rectum). Colonoscope is a flexible tube fitted with a light and camera. It is introduced into the colon through the rectum and allows the doctor to take pictures or videos of the entire colon till the lower part of the small intestine. The entire colon from the rectum to the small intestine can be examined for ulcers, polyps, inflammation or cancer. Colonoscopy can be diagnostic and therapeutic. A colonoscope can be used to remove polyps or take biopsies of the colon.
A successful colonoscopy requires clear visualization of the entire colon. Stool or fecal matter in the colon could obscure complete visualization of the colon, and therefore it is very important to have a good bowel preparation.
While preparing for a colonoscopy, after a thorough review of the patient’s medical history and chart, a doctor may prescribe PICO3 or sodium picosulfate. PICO3 is used as a contact laxative to empty the colon in preparation for a colonoscopy. PICO3 has been found to have the same efficacy, better taste, and fewer side effects compared to the rest of the methods used for bowel preparation for colonoscopy.
