I have had several ballon dilations in the past.
There is a risk of preforarion this can lead to emergency surgery, this ranges from 1-5%
They usually want steroids or infliximab first to reduce inflammation to reduce preforarion risk, however its low ish 1-5%
But on a positive note the feeling I felt after the ballon dilation was very nice, felt a lot better after.
I had one dilation last 2 years on one stricture, and another last ten years in on another, often they are a short term fix and don't last long sometimes just 2 months and narrowing is back.
Some steroids and infliximab and a ballon dilation can be a life changing bit of treatment in a lot of people, and day to day life becomes much better, with the chance to delay or avoid surgery.
I went about 12 years undiagnosed, remember being very young thinking how are all these people eating all these foods looking happy and smiley with no issues.
There is a newish procedure needle knife I think it's called, the chance to avoid surgery and a bit lower risk with longer lasting results via same tools and ballon.
The dream for strictures, would be an injection into the stricture tissue under endoscopy or colonoscopy, and the injection of medication enables the tissue to repair.
Hope you get well soon.
