What procedure involves using a flexible colonoscope?

The procedure that involves using a flexible colonoscope is the colonoscopy. This procedure is specifically designed to examine the interior of the colon (large intestine) and rectum for any abnormalities, such as polyps, inflammation, or cancer. During a colonoscopy, the flexible colonoscope, which is equipped with a camera and light, is gently inserted into the rectum and advanced through the colon. This allows the healthcare provider to view the lining of the colon on a monitor in real-time and, if necessary, to take biopsies or remove polyps.

Gastroscopy refers to the examination of the upper digestive tract using a gastroscope, which is not designed for use in the colon. Endoscopy is a broader term that refers to the examination of internal parts of the body using an endoscope, which can include various types of scopes for different regions, but it does not specifically refer to colon examination. A CT Scan is an imaging procedure using X-rays to create detailed pictures of organs and does not involve the use of a flexible colonoscope. Therefore, the colonoscopy is the specific procedure that directly utilizes the flexible colonoscope for examination of the colon.
