A flexible sigmoidoscopy (flex-sig) is a simple procedure that lets your doctor check the lower part of your colon and rectum to help keep your digestive system healthy.

A soft, flexible tube with a small camera at the tip is gently guided a short distance into the colon. This allows the doctor to clearly see the lining of your lower colon and rectum. The procedure is safe, quick and done under sedation with your comfort in mind.
