Sigmoidoscopy, flexible; with ablation of tumor(s), polyp(s), or other lesion(s) (includes pre- and post-dilation and guide wire passage, when performed)

A flexible sigmoidoscopy is a medical procedure that involves the use of a flexible tube equipped with a light and camera, known as a sigmoidoscope, to examine the lower part of the colon, specifically the sigmoid colon. This procedure is performed to identify and treat abnormalities such as tumors, polyps, or other lesions within the rectum and sigmoid colon. During the procedure, the sigmoidoscope is inserted through the anus and advanced through the rectum into the sigmoid colon. Air is insufflated to expand the colon, allowing for a clearer view of the mucosal lining. Once the scope is in place, the physician carefully inspects the mucosa for any lesions that may require treatment. If any tumors, polyps, or lesions are identified, ablation techniques are employed to destroy these abnormal growths. This may involve the use of a laser device, which is delivered through the endoscope to precisely target and ablate the lesions. The procedure also includes pre- and post-dilation steps, which may involve the use of guide wires and balloon catheters to facilitate access to the lesions. The goal of this procedure is to effectively remove or destroy the identified lesions while minimizing any potential complications or injuries to the surrounding tissue.
