They were going to do that for my TI stricture until they found a lot more problems north of there.
My Doc, whom I trust a lot, says it's a piece of cake IF they can get the scope into the stricture well. It's basically the same procedure for blood vessels when they want to open them.
Everyone in my area uses light anesthesia for colonoscopy, so we are asleep for the procedure so wouldn't feel a thing. I've read on here several that were awake. OMG, you brave folks. Did that once years ago, and never again!
I personally would not hesitate to get that done, I had HOPED to get it done instead of my current care.
Good Luck!
