The aim of this study is to estimate the risk of obtaining high\u2010risk findings (HRF<\/jats:styled-content>) on the next surveillance colonoscopy using the results of two previous colonoscopies, and to estimate the appropriate time interval for the next surveillance colonoscopy.<\/jats:p><\/jats:sec>Methods<\/jats:title>Among subjects who underwent screening colonoscopy during J<\/jats:styled-content>anuary 2002\u2013D<\/jats:styled-content>ecember 2009, patients who underwent second surveillance colonoscopy before J<\/jats:styled-content>une 2012 were enrolled. \u201cNo adenoma\u201d was defined as a hyperplastic polyp or no polyp, \u201clow\u2010risk findings (LRF<\/jats:styled-content>)\u201d as one or two small (<\u20091\u2009cm) tubular adenomas, and \u201cHRF<\/jats:styled-content>\u201d as advanced adenoma, cancer, or any sized multiple (\u2265\u20093) adenomas.<\/jats:p><\/jats:sec>Results<\/jats:title>Among enrolled 852 subjects, 65 (7.6%) had HRF<\/jats:styled-content> at second surveillance colonoscopy.
