Study Comparing the Quality of Colon Cleanliness With Prepackaged LRD (Low-residue Diet) vs. Guided (POG).
A Single-blind, Randomized Study Comparing the Quality of Colon Cleanliness With Prepackaged LRD (Low-residue Diet) vs. Guided (POG).
Source: ClinicalTrials.gov · Last updated 17 Feb 2026
Brief summary (registry, in English)
Low-residue diet (LRD) in patient improves the quality of the colon cleanliness and thus the adenoma detection rate (ADR). This is a key criterion in colonoscopy screening for colorectal cancer (CRC). The benefit of an LRD lasting more than 24 hours before colonoscopy has not been demonstrated compared to a 24-hour LRD. Few studies have evaluated the benefit of a prepackaged 24-hour LRD compared to simply receiving oral and written LRD instructions during a consultation. The aim of the study is to evaluate the usefulness of a prepackaged LRD (Colobox®) compared to simple LRD instructions on colon cleanliness (Boston score) in patients examined by endoscopy.
