What is Colonoscopy?


If you have a personal history of adenoma(s) or a significant family history of colon cancer, your doctor may refer you directly for colonoscopy. You may also be referred for colonoscopy following an abnormal fecal immunochemical test. In both cases, a patient coordinator in your community will discuss the procedure with you. 

Colonoscopy is a procedure where a doctor uses a flexible tube with a miniature camera attached to view the inside lining of your rectum and colon. During the test, the doctor can find and remove most polyps and some cancers.

Risks

As with any medical procedure, colonoscopy has a small risk of complications.

Approximately 5/1,000 people will have a serious complication. Complications can include a reaction to the bowel preparation or medication used for sedation, heart or lung problems, an infection, bleeding from the colon and/or perforation of the colon (hole in the colon).

If a complication occurs, treatment including antibiotics, blood transfusion, hospitalization, repeat colonoscopy or surgery may be required. The risk of dying from colonoscopy is less than 1/14,000. There is also a risk of missing a significant abnormality. This occurs in less than 1/10 cases.
