Prior to the examination, patients are usually required to follow specific dietary restrictions and take laxatives to ensure that the colon is clear. This preparation is crucial, as it allows for a clearer view during the procedure.During the sigmoidoscopy 乙状结肠镜检查, patients are typically positioned on their side, and a lubricated scope is gently inserted into the rectum.
