Can you tell me about colonoscopy?

What is colonoscopy?: Colonoscopy is an examination that enables a careful evaluation of the lining of the colon (large intestine) for abnormalities. It is performed by inserting a colonoscope (that is constructed with a flexible tube with a camera at the end) into the anus and slowly advancing it inside the colon: http://www.Laendo.Net/english/what-is-a-colonoscopy-70263428.

Much to say: Its a procedure that allows for examination of the colon and part of the small intestinal by direct visualization(seeing it) and also the opportunity to complete procedures when necessary. After a pre-procedure preparation that "cleans out the intestinal tract", it involves sedating a patient(usually!) and then maneuvering the camera on "bendable stick" through the lower intestinal tract.

Colon exam: Improved techmique for examing the whole colon over previous sigmoidoscopy. It is best performed by use of a long flexible scope in a bowel that has undergone cleansing (bowel prep). Virtuial colonoscopy defined by radiological exam has been used with some value, not requiring insertion of scope into rectum. Early polypoid tumors and cancers can be detected when asymptomatic
