A consensus document on bowel preparation before colonoscopy: prepared by a task force from the American Society of Colon and Rectal Surgeons (ASCRS), the American Society for Gastrointestinal Endoscopy (ASGE), and the Society of American Gastrointes

摘要

Colonoscopy is the current standard method for evaluation of the colon. Diagnostic accuracy and therapeutic safety of coionoscopy depends on the quality of the colonic cleansing or preparation. The ideal preparation for colonoscopy would reliably empty the colon of all fecal material in a rapid fashion with no gross or histologic alteration of the colonic mucosa. The preparation also would not cause any patient discomfort or shifts in fluids or electrolytes and would be inexpensive.1 Unfortunately, none of the preparations currently available meet all of these requirements.A brief history of the evolution of bowel preparation for colonascopy will be discussed followed by an evidence-based analysis of the various colonoscopy preparations, dosing regimens, and adjuncts currently used.
