Disappointed - another stricture!
I am a patient who had a stricture that was dilated 5 times before it was cured. I make too much scar tissue, which also happened with my hysterectomy so I should have known. Anyway you sound like you also have stubborn scar tissue. The GI specialist who finally solved the problem injected a drug called kenalog into all four quadrants of the scar tissue after the balloon dliation and "VOALA" it was fixed. I live in NC and my specialist is Dr Al-Sabbagh, he does a lot of corrections for RNY issues.
Wish you the best
