This week, Prof Marco Bruno, Department of Gastroenterology and Hepatology at the Erasmus University Medical Centre in Rotterdam is explaining about the problem we have with scope contamination.  Last year his department published a Nationwide Study of bacterial colonization of endoscopes. The study included 74 Dutch Centres and reported that 17% of duodenoscopes and 13% of EUS scopes were contaminated!  What can we do about this? With Marco, I discuss the current situation and possible solutions, like new endoscope designs, continuous monitoring and culturing of scopes and the training for reprocessing colleagues.
