Abstract

This paper examined the effects of experience, withdrawal speed and monitor size on colonoscopists' visual detection of polyps during colonoscopy. Five novice and five expert colonoscopists participated in a simulation experiment, where they viewed colonoscopy videos and indicated the presence or absence of polyps. Hit rate and false alarm rate of polyp detection were calculated and analyzed. The results showed that expert colonoscopists had superior visual detection skills in terms of hit rate. An increase of withdrawal speed significantly reduced the hit rate for both novice and expert colonoscopists.
