Effect of Continuous Nutritionist-led Guidance on Bowel Preparation in Patients Undergoing Prostate Stereotactic Body Radiation Treatment With Endorectal Spacing

Intense dietary consultations effectively reduce rectal gas and variation of rectal volume during prostate SBRT with endorectal spacing. However, there was no advantage in reducing prostate displacement. Thus, labor-intensive daily nutritionist intervention with biofeedback is not cost-effective in reducing organ motion in patients with endorectal spacers compared with standard pretreatment dietary advice and is not recommended.
