What is going to happen?
You will be asked to lie on your side and a rectal examination performed to make sure there are no tumours close to the anal margin. A small tube is gently inserted into the rectum which is secured with a balloon filled with air. Barium is allowed to flow in under gravity and coat the mucosa of the large bowel. Excess barium is then removed and air is gently pumped in to distend the bowel. This may cause some abdominal discomfort with will be relieved by using an intravenous anti-spasmodic drug. Representative pictures are taken.
