<div class="paragraph">
<div><span style="color: #00826a;"><strong>Colonoscopy</strong></span> is a safe and effective method for evaluating problems in the colon by using a colonoscope, which is a small, thin, long, and flexible tube equipped with a video camera and a very small light at the tip. When the colonoscope is properly maneuvered and adjusted, the doctor can move the scope inside the colon in the desired direction. The images captured inside the colon are displayed on a television screen, providing high-quality, clear images and allowing detailed examination of the entire colon, which is more accurate than X-rays.</div>
<div></div>
<div>Currently, the colonoscopy equipment at Phyathai 2 Hospital has an NBI mode that enhances the view of cells or blood vessels more clearly. The color changes from pink to blue, allowing differentiation of cells and blood vessels without the need for dyeing or injection.</div>
