A flexible sigmoidoscopy is a diagnostic procedure that allows for the examination of the lower part of the colon, specifically the sigmoid colon, using a flexible tube known as a sigmoidoscope. This procedure is particularly significant as it enables the physician to visualize the rectum and sigmoid colon, which are critical areas for identifying abnormalities such as tumors, polyps, or other lesions. 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 enhance visibility. Once the sigmoidoscope is in place, the physician withdraws the scope slightly to inspect the mucosal surfaces thoroughly. If any tumors, polyps, or lesions are identified, hot biopsy forceps are employed to remove these abnormal growths. The hot biopsy technique is particularly effective as it utilizes insulated monopolar forceps that not only excise the tissue but also cauterize it simultaneously, minimizing bleeding and promoting healing. This method is especially useful for small polyps and the treatment of vascular ectasias. After the removal of the lesion, the endoscope is withdrawn, and the mucosal surfaces are inspected once more for any signs of ulcerations, varices, bleeding sites, strictures, or other abnormalities that may require further attention or intervention.
