Colorectal cancer (CRC) is a major health problem in the world as it has been described as one of the most common causes of cancer-related death1. An early diagnosis is crucial for patient survival and also their quality of life2. Effective CRC screening and diagnosis usually relies on a total colonoscopy, which is widely used for the diagnosis and treatment control of colon disorders (e.g. large-bowel symptoms, iron deficiency, anaemia, postpolypectomy as well as diagnosis and surveillance in inflammatory bowel disease)3. Prior to a colonoscopy, bowel cleanser preparations have to be applied.
