I had an obstruction a couple years ago, and they wanted to do surgery. I'm glad I didn't go along with it. Today, I'm on Humira and eating SCD and am doing quite well. Fatigue is the only big thing I really deal with, and hopefully a few months more of the diet will take care of that.
Personally, I'm very leery of surgery. One person I know has had multiple surgeries which has led to major scar tissue and misery for her. Another person did pretty well after 2 surgeries, but still suffered from diarrhea. Her crohn's is back now, but she did have several good years where D was the only real symptom. My dad's surgery saved his life (he had peritonitis), but the crohn's returned almost immediately. Only anecdotal evidence of course, but still enough for me to save surgery as a last resort.
Have you tried remicade, humira, or cimzia?
