Two Low Volume Regimens for Colorectal Cancer Screening Colonoscopy

Summary

Colorectal cancer is the first neoplasm most commonly diagnosed in both sexes and the second leading cause of cancer death in Spain. Colorectal cancer screening Program in Barcelona was implanted in 2009 and approximately 1,500 colorectal cancer screening colonoscopies are performed annually at Hospital Clínic de Barcelona. Adequate colon preparation (anterograde cleansing with laxatives) improves polyp detection, decreases examination time, and complications. There are both low and high volume intestinal regimens with polyethylene glycol (PEG) as the main active ingredient or without it. Hypothesis: Two low volumen regimens, 1L PEG plus ascorbate and magnesium citrate plus picosulphate, at starting doses have the same Adenoma Detection Rate as cleansing solutions in preparation for screening colonoscopy.
