barium meal

An X-ray examination enhanced by the use of the insoluble barium sulphate, usually in the form of a liquid suspension. Barium is opaque to X rays and will thus reveal the internal structure of a hollow organ. Barium X rays are useful in the investigation of any part of the digestive tract. They can reveal out-pouchings from the lower part of the throat (PHARYNGEAL POUCH), narrowing (stenosis or stricture) of the gullet (oesophagus), swallowing disorders, HIATUS HERNIA, stomach and duodenal ulcers, tumours or POLYPS anywhere in the bowel but especially in the colon, abnormal pouches (diverticula) in the colon, CROHN'S DISEASE (regional ileitis) and COELIAC DISEASE.
