I had 2 sections taken out (about 7 feet) small bowel resection when I was 19.
I am now 36, it has not come back.
Occasional bouts, I think that are due more to scar tissue of reconnection of the bowel then the actual CD.
Either way its been a number of years, I have been on 6MP since the surgery and Remicade for I think the past ten years.
