I was recently in your shoes. Ultimately, I decided to have the stricture cut out BEFORE it became an emergency situation. This was 3 weeks ago this Tuesday. My surgeon said he didn't know how I wasn't continually having obstructions (I averaged 1 or 2 a year). They took out just a small area, the ileocecal valve/appendix/cecum.
While surgery wasn't a picnic, it also wasn't horrid. It was laproscopic, so I'm recovering quickly. I only spent 2 1/2 days in the hospital.
Like you, I'm sticking to SCD for at least 5 years, and probably for life!
Good luck with whichever route you choose
