Abstract

Background: Radiotherapy is typically regarded as an absolute exclusion criterion for prostate cancer radiotherapy treatment in patients with active inflammatory bowel disease. There are no reports on the application of a biodegradable rectal balloon implantation for prostate cancer radiation in patients with active IBD. Presentation of the case: We describe a guy who had high-risk prostate cancer and an active IBD with pancolitis as a concomitant condition. Neo-adjuvant hormonal therapy and high-dose external beam radiation to the prostate and seminal vesicles were used in his treatment. In order to move the rectum outside of the high-dose region prior to radiotherapy treatment, a biodegradable RBI was inserted between the prostate and the anterior rectal wall. The prostate of this patient, who was at high risk for rectal toxicity, was effectively exposed to radiation using only a grade A biodegradable sub acromial spacer of the In Space type was the foundation of a minimally invasive procedure that was recently released on the market. As the name implies, the treatment entails inserting this saline-filled device as a spacer between the acromion and the humeral head in the sub acromial space.
