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 remove abnormal growths such as tumors, polyps, or other lesions using a technique called snare technique. During the procedure, the sigmoidoscope is carefully inserted into the anus and advanced through the rectum into the sigmoid colon. To facilitate a clear view, air is insufflated into the colon, which helps to separate the mucosal folds and allows for better visualization of the internal structures. Once the sigmoidoscope is in place, it is withdrawn to allow for a thorough inspection of the mucosal surface. If any tumors, polyps, or lesions are detected, a wire snare loop is positioned around the lesion. This loop is then heated to effectively shave off and cauterize the lesion, minimizing bleeding and promoting healing. The lesions can be removed in one piece (en bloc) with a single snare placement or in smaller fragments (piecemeal), which may require multiple snare applications. After the removal of the lesions, the endoscope is withdrawn, and the mucosal surfaces are re-examined for any signs of ulcerations, varices, bleeding sites, strictures, or other abnormalities that may require further attention.
