Colonoscopy

A large number of abstracts dealing with colonoscopy were presented at the Digestive Disease Week meeting held in New Orleans in 2004. Many were concerned with technological innovations in colonoscopy. Others topics dealt with included the efficacy, safety, and tolerability of various colon-cleansing agents; miss rates for colon cancer during routine and surveillance colonoscopy; virtual colonoscopy; methods of reducing colonic motility during colonoscopy; chromoscopy; and the usefulness of terminal ileal intubation during colonoscopy. A host of abstracts dealing with miscellaneous other topics were also presented; this review focuses only on what appeared to the author to be the most relevant presentations.
