Bowel issues after anal cancer treatment: Had the interstim procedure?

Posted by geriincary @geriincary, Oct 6, 2023

After anal cancer treatment (radiation and chemo) I am having trouble with my bowels. Going to the bathroom 3-4 times a day. Have had physical therapy (pelvic floor) didn't seem to help. This procedure is an insertion of a wire and a pacemaker kind of devise to help control the muscles near the rectum.

Interested in more discussions like this? Go to the Colorectal Cancer Support Group.

You got it. I stay close to the bathroom every morning. A gastroenterologist prescribed amitriptyln . Off use. It seemed to help for awhile. but then nothing and my gp said it could cause memory problems. So that's where I am at. My surgeon that followed my treatment (no surgery) referred me to the Cleveland Clinic but I live in the Chicago area. Thanks for the info.

I’ve had bowel incontinence for years. Had my Interstim put in in January after what we thought was a really successful trial. I’m afraid it hasn’t really helped. I have cycled through many many settings and the only thing I can say is that it has made me even more aware of how little time (seconds) I have to get to the bathroom on time. I am currently on a program where the device is turned off for 23 hours and then comes on once a day - no real difference. The thing that seems to be helping the most is trying to make my bowels VERY regular - frustrating problem to be sure.
Providers are kind, but they always say the same things “don’t give up” “everyone is different” “we have other programs to try” . . .

After a successful trial, I had the device implanted 10 days ago (bladder problems from anal cancer radiation 23 years ago), and it’s been miserable… from nausea to peeing every hour…can’t seem to get the settings right to recreate the trial success (Medtronic rep has been responsive and helpful).
I’m interested in hearing from anyone who had similar trial & error experiences… did it eventually work? How long did it take? Has anyone had it removed then had subsequent luck with PTNS or Emselle?
Trying not to get discouraged here!!!

I am having the same experience. I had a successful trial (peeing about every 3 hrs is good enough!) mid-October and have tried 5? 6? Programs since then. I have peed every hour day & night, thrown up, had diarrhea — miserable. Then I end up retaining, having to be catheterized, get a UTI, and have 10 days of antibiotics before we can try a new program. Medtronic rep told me retention patients may take a year to find the solution. I, too, am very overwhelmed and discouraged. Hard to understand how the trial could be so good and the real thing so problematic. I would love to hear from anyone who struggled but did eventually get it right.

I am also interested in hyperbaric oxygen treatment (in addition).
