The time taken to withdraw the colonoscope during a medical test or evaluation. This is the duration it takes to remove the colonoscope from the caecum (considered to be the start of the colon) to the rectum.

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.
