Colorectal cancer is the second‑most common cause of cancer-related deaths in the world. The natural history of colorectal cancer carcinogenesis through the adenoma-carcinoma sequence permits screening programmes to detect and remove pre-cancerous lesions. Inadequate bowel preparation has been associated with a 47% lower likelihood of adenoma detection, compared with adequate preparation – defined in terms of the proportion of the bowel visible. Poor bowel preparation results in longer or repeated procedures, with further cost and risk to the patient.
