Bisacodyl micro-enema before MRI of rectal tumors: effects on rectum, image quality and patient acceptance

Question Bisacodyl micro-enema can improve MRI of early stage-rectal tumors, but the impact on rectal physio-morphology, image quality, and patient acceptance is unknown. Result Bisacodyl micro-enema increased the submucosal width and intraluminal fluid, did not distend the rectum, improved image quality, and was well tolerated by the patients. Clinical relevance Bisacodyl micro-enema represents a reliable preparation before MRI of rectal tumors and can improve imaging of early-stage cancer. This is increasingly important because of the shift toward earlier stages due to screening programs and the growing use of organ-saving treatment.
