Colonoscopy is currently most effective procedure used for detecting colon cancer especially
in the early stages. Screening colonoscopies are performed in the symptom-free patients at
risk of familial colon cancer. During colonoscopy air commonly used to insufflate the bowel
may be retained after the procedure causing pain and discomfort to the patients. One of the
methods used to reduce pain and discomfort is insufflation of carbon dioxide (CO2) instead of
air during colonoscopy.
Aim of the study is evaluation of the use of carbon dioxide insufflation during colonoscopy.
