Ep. 191 Optimizing Radiation Therapy: Role of Perirectal Spacers with Dr. Eric Chenven and Dr. Nadim Nasr

I warn them that once that spacer goes in, they will have feeling of rectal fullness, feeling like they have to have a bowel movement. I remind them that they just had an enema a little while ago and there's really nothing to come out. and so that tends to relax them.

Once we finish the procedure, we tend to get their legs down, tend to get their legs to bend their knees up a bit, and I think that helps them a little bit with that sensation, and it generally goes away within a few minutes. I do warn them that they may see a little bit of blood in the urine or stool for a day or so after treatment.

Obviously, most of these gentlemen have had a prostate biopsy not too long before, and so they're pretty familiar with that. And that's really about it for the side effects. I mean, I prepped them and most of our talk obviously is on the side effects of the radiation, not necessarily this.

Because we're moving to so much SBRT now, all of those patients, and we have a CyberKnife as well. That's our main SBRT unit. All of those patients are planned with both CT and MRI imaging. When we do our treatment planning, we're doing a CT simulation in our department And then they're going straight to radiology for an MRI right away in the same day.

And then we fuse those images based on the fiducial markers. And so you get a nice registration of the two images. And you can see that hydrogel very nicely on those MRIs. And where will there be a benefit using the spacer view? There was a short time period where we were doing a lot of spacer and we were still doing a lot of IMRT that was purely CT based for planning.

And I did use it for a brief amount of time there. But again, now that most of what we're doing is based on both CT and MRI imaging, I don't really use it anymore.

So we're a little bit different. I mean, we're a hospital-based group in the sense that we contract out to the hospital to do all their radiation professional services, but the technical fees still go to the hospital, including a lot of the technical fees for the equipment, the medications, the gels, and things like that. So that's a loop through the hospital process.
