To prep or not to prep – that is the question: A randomised trial on the use of anti-flatulent medication as part of bowel preparation for patients having image guided external beam radiation therapy to the prostate.

Radiotherapy is a standard treatment option for prostate cancer. With growing use of escalated doses and tighter margins, procedures to limit rectal size variation are needed to reduce prostate motion, increase treatment accuracy, and minimise rectal toxicity. This prospective study was done to determine whether the introduction of an anti-flatulent medication would decrease rectal distention at computed tomography simulation and throughout a course of radiotherapy.
