I too have a stricture in my sigmoid colon. I did discuss dilation with a colorectal surgeon last year and in his words, "I currently feel that it would be ill advised to dilate her with these active linear ulcers, but if she were to respond medically, certainly one could consider that." I think the risk being greater of perforation. Colonoscopy in January still shows active Crohn's at the stricture site, plus I had an endorectal ultrasound after that. We have decided on surgery.
Disease is found only at that site and strictureplasty was never given to me as an option.
