Btw, my daughter's stricture was easily visible on a cat scan (with contrast) and SBFT. It was so bad that one GI suggested surgery right away, saying the surgery could give her 7 great years. I thought, "So what, after seven years she will be only 25 - what about
the rest of her life???"
Today, thanks to meds and diet, the stricture is gone - we couldn't believe our eyes when we saw the SBFT and colonoscopy in 2008 and 2009, which both confirmed it was gone. So I'm not going to assume your stricture is scar tissue.
Surgery is almost never a permanent solution for a Crohn's patient. While there's no question surgery can be a blessing for Crohn's not responding to any med or diets, I do think in your case the doc's attitude to the pill cam getting stuck is a little cavalier.
Even pill cams which supposedly can be dissolved scare me, as I'm pretty sure somebody posted on healing well talked about such a pill cam getting stuck.
