Bowel Preparation

The ideal bowel preparation for colonoscopy safely clears the colon of fecal material, exposing the mucosa and rendering it amenable to thorough inspection. Substantial evidence exists that better colon preparation is associated with increased detection of colon polyps. Recently, several articles have reviewed the subject of bowel preparation for colonoscopy and compared the efficacy, safety and tolerability of the available formulations. Additionally, a multisociety consensus document on this subject was released by the American Society of Gastrointestinal Endoscopy (ASGE) and American College of Gastroenterology.[1] This section focuses on current research regarding dietary considerations, new preparation formulations, the timing of preparation administration and predictors that help to identify patients who are most likely to have an inadequate bowel preparation.
