Brief summary

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.

Design outcomes

Primary

MeasureTime frameDescription
Boston Score1 dayA 9-point system, helps them see how clean a patient's large intestine is during a colonoscopy. This scale divides the large intestine into three parts: right, middle, and left. Each part can score from : BBPS = 0 (per segment) : unprepared colon segment with mucosa not seen because of solid stool that cannot be cleared. BPPS=3 (per segment) : entire mucosa of the colon segment seen well, with no residual staining, small fragments of stool, or opaque liquid.
