A Trial to Compare Efficacy and Tolerability of Plenvu® and Picoprep® as Cleansing Agents Before Colonoscopy

The trial is about comparing the efficacy of Plenvu with Picoprep. Both are bowel cleansing agents prior to visual examination of the large bowel to exclude cancer disease. 400 patients who are referred for colonoscopy to a single center in North Jutland will be randomised either to Picoprep or Plenvu. These patients will then answer a questionnaire prior to colonoscopy. The questionnaire is about the most common expected side effects and the experience of cleansing og intake of the bowel agents. The effect of the two agents will examined using a special scoring system (Harefield) to determine the quality of bowel cleansing. Colonoscopist who evaluate the cleansing is blinded to which agent the patient has taken.
