Background Colonoscopy is the standard method for luminal evaluation of the colon. Bowel cleansing prior to colonoscopy is critical to the endoscopist obtaining optimal visualization during the procedure and therefore plays an integral role in safety, efficacy and diagnostic accuracy of the procedure. The bowel cleansing portion of the procedure is often the most lamented aspect of the colonoscopy experience. This is often driven by the large volume of liquid required to be consumed, in addition to the poor palatability of some colon cleansing regimens. Cleansing methods are variable, and often times high volume solutions are time consuming, inconvenient and uncomfortable, leading to poor patient compliance. This translates into decreased effectiveness of the colonoscopy exam and often higher costs due to the need for repeat examination. Additionally, it is unknown how much the feared discomfort of the bowel preparation experience dissuades patients from pursuing a screening colonoscopy for colon cancer.
