Today I am talking to Dr Nick Burr, one of our Rising Stars in Gastroenterology, working in Leeds.  You may recognise his name from some of the most influential papers written on the topic of ADR and PCCRC in the recent past.  I’ve decided to ambush him with some difficult questions about our unhealthy obsession with ADR and see if I can convince him that the PCRCR rate is irrelevant to individual colonoscopists.  I am armed with the references below to support my argument !  Karminski MF.
