Guide for use: | The American Society for Gastrointestinal Endoscopy and the American College of Gastroenterology Taskforce on Quality in Endoscopy (2006) stated that longer colonoscopy withdrawal times have been demonstrated to improve polyp detection rates, and, conversely, rapid withdrawal of the colonoscope may miss lesions and reduce the effectiveness of colon cancer prevention. In Australia, the standard withdrawal time should be at least six to eight minutes. This will ensure that sufficient care has been taken to thoroughly inspect the bowel for abnormalities. |
