The BARRIGEL rectal spacer is a medical device used in patients undergoing radiation therapy for prostate cancer. This hydrogel spacer is designed to create a temporary space between the prostate and the rectum, reducing the risk of radiation-induced damage to the rectum. Here is an overview of the
procedure and its benefits:
Procedure Overview
- The patient is usually given an enema to clear the rectum.
- The procedure is typically performed under local anesthesia, sometimes with sedation.
- The patient is positioned similarly to how they would be for prostate biopsies.
- Using transrectal ultrasound (TRUS) guidance, the physician inserts a needle through the perineum (the area between the scrotum and anus) to the space between the prostate and rectum.
- The BARIGEL hydrogel is injected through the needle. The hydrogel expands, creating a physical separation between the prostate and rectum.
- The procedure usually takes about 30 minutes.
- After the injection, the spacer remains in place for the duration of the radiation treatment, typically about three months.
- The hydrogel spacer is absorbed by the body and excreted through urine after it has served its purpose.
Benefits
- The primary benefit is the significant reduction in the dose of radiation that reaches the rectum, which minimizes potential damage.
- By sparing the rectum from high doses of radiation, patients experience fewer side effects such as rectal pain, bleeding, and long-term bowel issues.
- With fewer gastrointestinal side effects, patients generally report a better quality of life during and after radiation therapy.
- The minimally invasive nature of the procedure means a quick recovery time, allowing patients to proceed with their radiation therapy without significant delays.
Considerations
- Not all patients are candidates for the BARIGEL rectal spacer. Suitability is assessed based on individual anatomy and medical condition.
- As with any medical procedure, there are potential risks including infection, bleeding, or discomfort at the injection site. However, these complications are generally rare.
Post-Procedure Care
- Patients might experience some mild discomfort or pressure in the perineal area, which usually subsides quickly. Follow-up appointments are scheduled to monitor the position of the spacer and ensure it is providing the desired separation between the prostate and rectum.
The BARRIGEL rectal spacer is an innovative solution to improve the safety and effectiveness of prostate cancer radiation therapy, helping patients undergo treatment with fewer complications and a better overall treatment experience.
