Advantages
VC is more comfortable than conventional colonoscopy for some people because it does not use a colonoscope. As a result, no sedation is needed, and the patient can return to his/her usual activities or go home after the procedure without the aid of another person. The lack of sedation also lowers the risk of the procedure since some people may have adverse reactions to sedative medications used during conventional colonoscopy. VC provides clearer, more detailed images than a conventional x-ray using a barium enema, sometimes called a lower gastrointestinal (GI) series. Further, about 1 in 10 patients will not have a complete right colon (cecum) evaluation completed with conventional colonoscopy. It also takes less time than either a conventional colonoscopy or a lower GI series.
VC provides a secondary benefit of revealing diseases or abnormalities outside the colon.

Famous quotes containing the word advantages:
“There are great advantages to seeing yourself as an accident created by amateur parents as they practiced. You then have been left in an imperfect state and the rest is up to you. Only the most pitifully inept child requires perfection from parents.”
—Frank Pittman (20th century)
“We work harder than ever, and I cannot see the advantages in cooperative living.”
—Lydia Arnold, U.S. commune supervisor (of the North American Phalanx, Red Bank, New Jersey, 1843- 1855)
“Can you conceive what it is to native-born American women citizens, accustomed to the advantages of our schools, our churches and the mingling of our social life, to ask over and over again for so simple a thing as that “we, the people,” should mean women as well as men; that our Constitution should mean exactly what it says?”
—Mary F. Eastman, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4 ch. 5, by Susan B. Anthony and Ida Husted Harper (1902)
