A large number of high-quality studies important to colonoscopy were presented at
Digestive Disease Week (DDW) 2013, and the topics addressed by these studies reflect
current controversies in colonoscopic practice. Thus, bowel preparation, quality measurements
(particularly factors affecting adenoma detection), polypectomy technique, serrated
polyps, real-time histology, and water immersion were covered in great detail. Studies
covered here reflect the author’s perception of those providing new data or describing
new approaches to current controversies in colonoscopy.
