I have been struggling with an Rv fistula for 8 months. i have been to university of Chicago and Cleveland clinic. Both great centers for IBD that gave me good information. A big question has been if an incorrect diagnoses of uc & had crohn's all along. Chicago thinks I don't have crohns and Cleveland felt due to location of fistula they weren't sure. Both centers recommended pouch advancement or pouch redo but Cleveland said if there was uncertainty of crohns i may not have as good outcome. I went through hell last year with emergency surgery and recovery and now this fistula. I hate to go through more surgery .My quality of life right now isn't very good but what if it could be worse? can anyone let me know if they've experienced pouch advancement ? Thanks!
