Summary
Brief summary (as posted)
Colonoscopy is one of the most common methods for the diagnosis and treatment of lower gastrointestinal tract diseases and provides a unique opportunity to identify early neoplastic lesions. Adequate bowel preparation is important for optimal colonoscopy. New bowel-cleansing regimens, study of patient-related risk factors to fail a proper preparation and diet adaptations have been studied recently. A low residue diet is the standard in the day before the colonoscopy. Some endoscopists prescribe this dietary plan for a 3-day period prior to the exam, although no study compared the recommended 1-day versus 3-day diet regime, or the influence in bowel preparation results. The aim of this project is to determine if the use of a 3-day low residue diet improves bowel preparations results and the influence in patient tolerability and adherence.
