The diagnostic accuracy of colonic ultrasound, to problem solve suspected colon cancer following diagnostic CT. Can we reduce the need for Colonoscopy?

Purpose: Residual faecal material, poor insufflation, complex diverticular disease, segmental colitis and spasm can mimic tumours on diagnostic Computed Tomography (CT). We aim to evaluate the diagnostic accuracy of focused ultrasound (US) in characterisation of colonic pathology in patients following abdominal CT and CT colonography (CTC). US is used in our service to allow patients to proceed direct to surgery without confirmatory colonoscopy.
