Anal stretching

Do you mean he did a balloon dilation?

To tell you the truth I was under anesthesia for procedure so I don't know.  That is the way they have always done this. I never thought to ask.  They did try to stretch me at one time in the office and they were with long rods.  It was to painful so they always do it while I am under anesthesia.  

Yeah I got that done once when my UC was wrongly diagnosed for a anal fissure. They try stretching your butthole cause apperently sitting too long causes it to squeeze up not letting you pass stool properly. I think it was bullshit in my case the docs didnt even know it UC causing the blood and irregular BMs. Have you tried doing pelvic exercise. They might help you get over with the control. Earlier I found it difficult to empty my pouch too. Now I just go less and hold more. Also something that I found good for myself was if I sit when I have the urge to go by that I mean when the pressure is felt at bottom eveything comes out quick. I know there's no science behind it just my own way of clearing myself in one go.

Is this not referred to as Dilation rather than anal stretching

  During my takedown surgery I had dilation, although I didn't discover this until some months later during a consulation.

Dilation was required due to the narrowing of the anal canal, which apparently, is a normal part of the recovery process.

I assume it'll be the anal canal rather than the stretching of the anal sphincter, it's normally preferably that the anal sphincter remains tight to prevent leakage, which the pelvic floor exercises attempts to achieve.

Thank you everyone for your comments.  I will let you know what the doctors are telling what I have to. Thanks  Grace
