A Study to Investigate the Effect of a Meal At 6pm the Day Before the Colonoscopy on the Bowel Cleansing with Plenvu

To Dine or Not to Dine: Effect of Day-before Light Dinner on Bowel Cleansing Prior to Colonoscopy

Bowel cleansing prior to colonoscopy is crucial to be able to perform a high-quality examination. Therefore maximum efforts are made to achieve optimal bowel cleansing including diet restriction and refraining from day-before dinner. However, the effect of this interdiction is currently not clear. On the other hand, patient compliance and experience with the entire procedure is important, especially for follow-up colonoscopies. Strict diets may interfere with this as an additional burden on the patient. In this study we want to assess whether a more lenient diet influences the quality of bowel preparation and whether it improves patient's experience.
