Purpose
Barium enemas are most commonly used to check bowel health; they can help diagnose and evaluate the extent of inflammatory bowel diseases such as ulcerative colitis and Crohn's disease. Polyps can be seen, though not removed during the exam like with a colonoscopy— they may be cancerous. Other problems such as diverticulosis (small pouches formed on the colon wall that can become inflamed) and intussusception can be found (and in certain cases the test itself can treat intussusception). An acute appendicitis or twisted loop of the bowel may also be seen. If the picture is normal a functional cause such as irritable bowel syndrome (IBS) may be considered.
In a healthy colon, barium should fill the colon uniformly and show normal bowel contour, patency (should be freely open), and position.
Additional conditions under which the test may be performed:
- CMV gastroenteritis/colitis
- Hirschsprung's disease
- intestinal obstruction
- intussusception (children)

Famous quotes containing the word purpose:
“The technologist was the final guise of the white missionary, industrialization the last gospel of a dying race and living standards a substitute for a purpose in living.”
—Max Frisch (1911–1991)
“Your good mother tells me you are feeling very badly in your new situation. Allow me to assure you it is a perfect certainty that you will, very soon, feel better—quite happy—if you only stick to the resolution you have taken to procure a military education. I am older than you, have felt badly myself, and know, what I tell you is true. Adhere to your purpose and you will soon feel as well as you ever did.”
—Abraham Lincoln (1809–1865)
“To found a great empire for the sole purpose of raising up a people of customers, may at first sight appear a project fit only for a nation of shopkeepers. It is, however, a project altogether unfit for a nation of shopkeepers, but extremely fit for a nation that is governed by shopkeepers.”
—Adam Smith (1723–1790)
