Audit of colonoscopies carried out for the indication of abnormal radiological imaging over a 4 year period in a large tertiary referral centre

Aims A frequent indication for colonoscopy referral is abnormal findings on cross-sectional imaging or PET. Colonic abnormalities may also be incidentally detected in patients undergoing imaging for other reasons. Our aim was to determine the yield of endoscopy in the investigation of intestinal abnormalities detected on cross-sectional imaging.
