My personal approach to recommending virtual versus optical colonoscopies

  • In healthy patients who want all the polyps (including ones smaller than 5mm) to be removed, I recommend optical colonoscopy
  • In patients who do not want to undergo optical colonoscopy and are willing to accept the possibility of leaving small polyps untreated, virtual colonoscopy is an alternative to optical colonoscopy.
  • In unhealthy patients with advanced heart, lung, liver, or kidney diseases, virtual colonoscopy may be a safer and less invasive alternative to optical colonoscopy.
