Electric sphincter-stimulation instead of balloon-catheters

In the 1970ies, in the UK, there were test made to prevent leakage in barium-enemas with electric sphincter-stimulation instead of using inflateable catheters: https://www.ajronline.org/doi/pdf/10.2214/ajr.127.3.429

Has anybody had such an expierience? For me, this looks very interesting.

No, I've never heard of this, as far as barium enemas go, but I'd really like to try some kind of safe rectal estimulation. Anyone with any experience in this area?

Thank you!

Thanks @carlienet for a great find! I've just recently gotten interested in eStim activity. Being a tinkerer, I've made a couple of anal devices. They are made of PVC plumbing pipe. The electrodes are copper shielding tape that is normally used for guitar control cavities. Current is supplied by a TENS/EMS unit. After reading this paper I'm going to make an electric enema nozzle ASAP.

@Fullbottom I hope we will see a picture, once it's finished :-)

There are a number of e-stim butt plugs on the market that bear a very close resemblance to the canulae pictured in the study. The sensation they produce at higher intensity with no modulation (that is at a steady current rather than pulsing or fluctuating) seems to cause your anus to contract a bit - it is quite pleasant and erotic/stimulating. If you haven't experienced it, it's definitely worth the investment in a TENS unit (about $30) and the butt plug (around $25 if I remember correctly). ENJOY!!!

Having given barium enemas for years in the 90s, I was always using double balloon nozzles to keep from having to mop up the xray table and room. I've never seen the device shown but am familiar with the Tens units and electrified butt plugs. That would have been an interesting addition to the exams we did.

I frequently apply an electrode pad (one per side) to each side of the anal ring and attach to a tens unit. I usually connect the 2nd channel to one pad applied to the perineum and the other pad to the dorsal side of corona. Inserting a butt plug intensifies the sensations . Try it you'll like it.

I saw the procedure with the baloon catheter a few times and some patients has barium leaks due to low tone of their sphincter muscles or spasms of musculature in response of the distension of intestine walls. Indeed applying an electric stimulation it is possible to produce an efficient and controlled contraction against the tube wall avoiding any leakage. I experienced it on myself during trials of an anal manometry instrument having also electrodes on an hourglass shaped probe. After insertion the doctor started the stimulation and I had my rectal muscles all contracted on the probe. It was a powerful feeling accompanied by a complete lack of control on it. I no wonder doctors can use this tecnique to avoid any voluntary or involuntary squeezing or relaxing of the rectal canal that may provide a leakage during the barium exam.

Very interesting information. I have a modified balloon nozzle that I use with a TENS electrodes on it, and it does indeed tighten the anal sphincter in certain pulse patterns. However, I doubt that it prevents leakage. I enjoy it solely as anal stimulation. If you are interested, you can find photos of the nozzle in my album.
