In order to have an adequate view of the whole small intestine during capsule endoscopy,the preparation recommended consists of a clear liquid diet and an ovight fast.However,visualization of the small bowel during video capsule endoscopy can be impaired by intestinal contents.To improve mucosal visualization,some authors have evaluated different regimens of preparation.There is no consensus about the necessity of intestinal preparation for capsule endoscopy and it should be interesting to develop adequate guidelines to improve its efficacy and tolerability.Moreover,the effect of preparation type (purgative) on intestinal transit time is not clear.Since a bowel preparation cannot definitively improve its visibility (and theoretically the yield of the test),it is not routinely recommended.
