I can think of only one woman who had jpouch surgery after a fistula and her original diagnosis was FAP not UC. Most women with RV fistulas develop them after surgery. Sometimes it's because the condition was really Crohn's and not UC, other times it's related to infection during the first step of a jpouch, and I suppose there's a group of unknowns. You can always seek a second opinion from a top CR surgeon; one who has done 1000s of procedures.
