Core Tip

Core Tip: Currently, there is minimal consensus to inform clinicians of the appropriate approach to manage patients presenting with positive immunochemical fecal occult blood test (iFOBT) following a recent colonoscopy. This may lead to additional unnecessary, invasive procedure which confers procedure-related risks, as well as avoidable patient anxiety and a higher cost-burden on the healthcare system. Our study revealed that a previous colonoscopy, irrespective of its result, was associated with low prevalence of advanced neoplasia, and if performed within 4 years of a positive iFOBT result, was protective against colorectal cancer.
