I also have a very narrow stricture (mine is in the transverse colon) that is scar tissue. So it won't be going away no matter what medication I take. When I have a flare and there is inflammation on top of the scar tissue, the stricture makes life very unpleasant (causes bloating and discomfort because things can't pass through the stricture very easily, and I can only eat soft/liquid foods). It also causes constipation for me. When I feel good, like now, it doesn't bother me that much.
My GI also felt that a ballon dilation would be too risky and wouldn't help that much.
I have decided to have a resection or strictureplasty in the next couple months because I am hoping to have children soon. (Had a miscarriage in November and will TTC as soon as possible after the surgery.) For me, especially because of the location of the stricture, I am worried that the fetus could press down on the intestines and make the stricture even worse than it normally is. (And of course constipation is an issue even for healthy pregnant women, so this could be very uncomfortable.) I feel better knowing that I am going to get rid of the stricture and at least maximize my chances of having a healthy pregnancy and not being in constant Crohn's related pain. I think it is definitely legitimate to have the surgery, or at least discuss the options with your doctors, if you are planning to be pregnant in the near future.
good luck :)
