Hattie, I have an anal stricture. My colorectal surgeon did my dilation. I don't have problems with leakage though I have heard it can happen. I have to do self dilation from time to time to keep the stricture opened. I guess my advice for you would be to make sure that you have an experienced professional do the dilation. I definitely prefer my colorectal surgeon that did my surgery. My G.I. tried to do the dilation first, and that just didn't work out. Good luck. Let us know how everything goes.
