Hi, I have had three balloon dilatations this year in February, March and June. The only one that was successful in that they were able to "pass the scope" through was the one in March. Unfortunately in my case this stricture has grown longer and it cannot be dilated and so I am having a resection in two weeks.
The procedure is really just like a colonoscopy, I was sedated but could watch the process and they give you pictures of it afterwards!
Before I had this done I read that, providing the stricture is not too long, balloon dilatation has a high success rate and can delay surgery or even avoid it. I hope that this is the case for you. Good luck and best wishes.
