Bowel Cleansing Regimens – Pick Your Poison (Wisely)!

Colorectal cancer (CRC) is the second most common cause of cancer-related mortality in the United States. Screening is imperative because the early stages of CRC are often asymptomatic.Colonoscopy is an effective and widely employed screening option for CRC.  Suboptimal bowel preparation is a problem in more than 20% of colonoscopy procedures, which reduces adenoma detection rates (ADR). Day-before, split-dose, and same-day regimens are options for colon cleansing prior to a colonoscopy. Is one better than another in terms of tolerability and colorectal cancer detection?
