Yoga and Bolus Lukewarm Saline as Rapid Colonoscopy Preparation

A quality colonoscopy examination remains as the gold standard for colorectal cancer screening, but effective large bowel cleansing prior to colonoscopy is still not achieved in all cases that undergo the procedure. Currently, the most widely used cleansing methods employ balanced electrolyte-polyethylene glycol (PEG) solutions. However, a very large volume of PEG solution is required for it to be effective, and many patients refuse to drink a sufficient amount due to non-palatability. In this study, the investigators compare a novel colon preparation method--bolus lukewarm saline with yoga exercise--with a PEG based solution (HalfLytely) for large bowel cleansing.
