title: Unsedated colonoscopy: A neverending story.
abstract: Although sedation and analgesia for patients undergoing colonoscopy is the standard practice in Western countries, unsedated colonoscopy is still routinely provided in Europe and the Far East. This variation in sedation practice relies on the different cultural attitudes of both patients and endoscopists across these countries. Data from the literature consistently report that, in unsedated patients, the use of alternative techniques, such as warm water irrigation or carbon dioxide insufflation, can allow a high quality and well tolerated examination.
