Background: The UK Bowel Cancer Screening programme (BCSP) was launched in 2006 in England and following an age-extension, now screens individuals aged 60–74 years with a faecal occult blood test (FOBt) followed by screening colonoscopy if FOBt positive. We reported at ECCO 2012 the world’s first experience of incidental diagnosis of IBD through screening and now present an experience of incidental IBD over 7-years at our centre.
