A flexible tube with a tiny video camera attached (endoscope) is inserted through the mouth into the stomach and small intestine while you are under sedation (you have been given medication to make you drowsy). A smaller tube is then moved through the first tube into the bile duct (the tube that connects your gallbladder to your intestines) through which dye is injected and an x-ray is taken to visualise the ducts. This procedure also enables the removal of stones from the ducts without the need for surgery.
