In colonoscopy, preparation is often regarded as the most burdensome part of the intervention. Traditionally, specific diets have been recommended, but the evidence to support this policy is insufficient. The aim of this study was to evaluate the impact of the decision not to follow a restrictive diet on bowel preparation and colonoscopy outcomes.
Conclusions The liberal diet was non-inferior to the 1-day LRD, and increased tolerability. Colonoscopy performance and quality were not affected.
A non-inferiority randomised trial is a study designed to prove that a new treatment is not worse than an existing treatment by more than a pre-defined, acceptable margin.
A liberal diet isn’t about eating anything you want, but rather following a low-fiber diet for a few days beforehand, gradually transitioning to clear liquids the day before the procedure.
