Comparison of Two Preparations for the Study of the Colon Through Colonoscopy

Comparative, Prospective and Randomized Study of Two Preparations for the Study of the Colon Through Colonoscopy

Compare the quality of bowel preparation between two groups of patients, who will undergo two different preparations: 1. Moviprep + diet; 2. Plenvu + diet

The quality of bowel preparation is essential for the success of a colonoscopy, reducing colonoscopy duration, and increasing the rate of cecal intubation and of polyp detection. There are several types of preparations available on the market and, irrespective of the choice, the split-dose regimen should be followed. A reduced volume preparation makes the process easier and more tolerable, increasing adhesion. Regarding the diet to be applied before the examination, there are no advantages to a liquid diet compared to a low fiber diet, and there is no evidence on the duration of the diet. In addition, a restrictive diet has an impact on satisfaction and also on adherence to treatment.
