My son had a resection three years ago. What locked it in for us what that we requested that his GI, surgeon and radiologist all get in the same room and come to a definitive recommendation. In his case, the stricture he had was all scar tissue, which no medication can fix, and was only 3mm in diameter while a normal intestine is 3-5cm in diameter. It was a pretty obvious decision for us. His quality of life was non-existent as well and that, too, was a major factor.
Surgery went well. In on a Friday, home the following Thursday and back at school the Monday after that. Unfortunately, because he wasn't on the right meds, he ended up flaring again three months later, so be forewarned that surgery is not a permanent solution by any means. You're still going to have to figure out what maintenance medication will work. Has there been any talk of Entyvio?
I would wonder why you'd add methotrexate if surgery is drawing near, but the bigger question is if anyone can determine if scar tissue is involved.
Hugs to you...
