Clinic protocol intervals shown (fixed 1 / 3 / 5 / 7 / 10 years). Quality/safety overrides may shorten the interval.
Use Second surveillance when the patient already had a prior colonoscopy with polyps and then had a follow-up colonoscopy, and you are choosing the next interval.
Protocol: start at age 40 or 10 years younger than affected relative’s diagnosis (whichever is earlier), then repeat every 5 years until age 80 (if life expectancy >10 years).
Quality/safety overrides: incomplete exam or poor prep typically warrants earlier repeat.
Protocol focus: 7 years for a negative follow-up or 1 polyp after prior polyps; 10 years after two consecutive negative colonoscopies.
Intervals shown as fixed years per your protocol.
