About this study

It is very useful to use narrow-band imaging and Sano CP analysis in the differential diagnosis of colorectal lesions. The endoscopists who had never used NBI or no knowledge of NBI can have effective and stable diagnostic accuracy after using NBI with magnification to diagnose 15 target and non-target lesions respectively.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Ages 16 to 85
  • Any patient undergoing NBI with magnification colonoscopy exam and found with colorectal lesions

Exclusion criteria

  • Unwilling to consent
  • Had surgery of colorectal tumors
  • Using NSAIDS
  • Diagnosed or suspected IBD
  • Familial adenomatous polyposis(FAP) or hereditary non-polyposis colorectal(HNPCC) or other hereditary disease
