Predicting Suboptimal Bowel Preparation: Taking It Up a PEG

Excerpt

The increased incidence of colorectal cancer (CRC) over the last decades has driven the widespread launch of population-based screening programs worldwide, for which colonoscopy has become the primary diagnostic tool. Optimal bowel preparation is a pre-requisite for accurate and safe colonoscopy, as it enables adequate mucosal visualization, increasing the diagnostic yield for colonic lesions, supported by the observation that polyp and adenoma detection rates are directly proportional to the quality of bowel preparation. Improved colonic cleansing is associated with a fivefold increase in cecal intubation rates as well as a twofold increase in adenoma detection [1]. …
