Check colonsocopy again in 1 year ifpatient fit and willing四川省第四人民医院消化内科常玉英

If subsequent colonsocopy is negative foradenomas, low risk or intermediate risk then follow intermediate riskguidelines (next colonoscopy in 3 years).

If subsequent colonoscopy is incompletethen consider computed tomographic colonography (also known as CTC or CTcologram) instead or offer a repeat colonoscopy with a more experiencedcolonoscopist. The risks and benefitsshould be discussed with the patient (and their family and carers ifappropriate) and the patient's decision (or patient's advocate decision forpatient's who cannot consent) documented.

Check colonoscopy again in 3 years ifpatient fit and willing

If subsequent colonoscopy is negative foradenomas then repeat colonoscopy in 3 years again. Stop colonoscopic surveillance if there is afurther negative result.

If subsequent colonoscopy is low orintermediate risk then follow up as for intermediate risk (next colonoscopy in3 years).

If subsequent colonoscopy is high risk thenfollow up as for high risk (next colonoscopy in 1 year).
