An internal pilot study of a novel rectal mucocellular sampling device to allow next-generation sequencing for colorectal disease.

sampling device can capture rectal mucus from unprepared bowel in subjects who could undergo a digital rectal examination. The technique could be applied irrespective of age, frailty, or co-morbidity. Completion of the study to 800 patients and analysis of NGS data for colorectal cancer mutations will now proceed.
