Question
Kitty,
My understanding is that a stricture is a narrowing of the stoma - the opening of the stomach into the intestine. Narrowing can be caused by scar tissue after the surgery. I'm sure that there is more to it. If you go to the library of this site, you can get more information. Also, others will have more info for you.
Welcome to the Iowa boards and to the losing side of this journey!
God bless,
Andrea
