Several high-quality studies pertinent to colonoscopy were presented at Digestive
Disease Week (DDW) 2014. The following review discusses studies that are considered
to address some of the most burning questions in colonoscopy research: quality of
colonoscopy and its measurement, surveillance intervals for adenomas, the treatment
of diminutive adenomas, basic and advanced polypectomy techniques, and microbiome
changes in relation to colonoscopy.
