title: Conventional colonoscopy: technique, indications, limits.
abstract: Colonoscopy has long been the gold standard for the diagnosis of colonic diseases. Recently, with the advent of CT colonografy, new alternatives seem to appear on the horizon, which seem to finally overcome some of colonoscopy's drawbacks like procedure related pain and discomfort during the examination. Polyp miss rate and the fact that not always the caecum can be reached are also the basis of debate. This article gives an overview about current technique, indications and limitations of diagnostic colonoscopy as well as a potential prospect for the future, discussing novel imaging technologies ranging from magnification endoscopy to virtual histopathology.
