Full description

Enrolled patients, after providing written informed consent, are randomized to the CLENSIA preparation scheme, delayed full-dose or split-dose regimen. The delayed full-dose regimen will constitute study arm A while the split-dose regimen will constitute the control arm B.

Participants will follow a slag-free diet in the three days preceding the colonoscopy (reduction in the consumption of fruit, vegetables and legumes). On the day before the colonoscopy, patients will be able to have a normal breakfast and lunch that are both free of fiber. The dietary indications will be delivered in writing to the patient by the health staff of the center involved in the trial. From the moment the preparation begins with the intake of the product, the intake of solid foods will no longer be allowed while clear liquids of the patient's choice can be taken freely up to two hours before the colonoscopy.

The study ends for each patient with the execution of each procedure / examination planned for the visit 2 The effectiveness of the preparation in terms of intestinal cleansing is assessed blindly (by the endoscopist) using the scale (Boston Bowel Preparation Scale).
