A flexible sigmoidoscopy is a diagnostic procedure that allows for the examination of the sigmoid colon, which is the lower part of the large intestine. This procedure is performed using a flexible sigmoidoscope, a long, thin tube equipped with a light and camera, which is inserted through the anus and advanced through the rectum into the sigmoid colon. The primary purpose of this procedure is to identify and treat strictures, which are narrowings of the colon that can occur due to various factors such as previous surgeries, radiation therapy, or inflammatory diseases affecting the intestine. During the procedure, a transendoscopic balloon dilation technique is employed to widen the narrowed area of the colon. This involves the use of a specialized balloon device that is inserted through the sigmoidoscope and inflated at the site of the stricture. The inflation of the balloon is carefully monitored using a pressure gauge to ensure that it reaches the optimal level for effective dilation. After a brief period of inflation, the balloon is deflated and removed, allowing for a thorough inspection of the treated area to confirm the success of the dilation and to check for any potential injuries to the colon. This procedure is essential for alleviating symptoms associated with strictures and improving the overall function of the bowel.
