Summary
Brief summary (as posted)
Colonoscopy is the technique of choice for the evaluation of the mucosa of the colon. To be able to do the procedure in optimal conditions, it needs to be clean. Therefore, it is necessary to carry out a preparation as safe and tolerable as possible. This preparation generally consists in a low residue diet the days before the colonoscopy and in the intake of a laxative solution. In previous studies, it has been shown that the low residue diet does not play a relevant role as it was considered before. Recent studies demonstrated that reducing the days of low residue diet does not worsen the cleansing and improves the patient experience. The results of this study are required for determining the role of diet restrictive diet in colon cleansing.
