A flexible colonoscopy is a diagnostic and therapeutic procedure that involves the insertion of a colonoscope into the rectum and advancement through the entire colon to the cecum or the terminal ileum. This procedure allows for direct visualization of the mucosal surfaces of the colon, enabling the identification and assessment of abnormalities such as tumors, polyps, or other lesions. During the colonoscopy, air insufflation is utilized to expand the colon, which helps in separating the mucosal folds for improved visibility. When a lesion is detected, the procedure can proceed to the removal of the lesion using a snare technique. This technique involves placing a wire snare loop around the lesion, which is then heated to excise and cauterize the tissue simultaneously. The snare technique is particularly effective for removing larger lesions and can be performed either en bloc, where the entire lesion is removed in one piece, or piecemeal, where the lesion is removed in sections. Following the removal, the endoscope is withdrawn, and the mucosal surfaces are re-examined for any signs of complications such as ulcerations or bleeding.
