I had my jpouch surgery in 1993 and past 10yrs have had a retrovaginal fistula but pretty much all along have had an anal stricture. Dialation usually once a year is all I need. however since the birth of my child experience the need more often. Just say my surgeon at John Hopkins and she is suggesting Pouch Advancement but she herself has only done 3! So need information on anyone who has had this surgery and how successful it was or wasn't and also who performed it for you. She is recommending a consulation with Dr. Hull at the Cleveland Clinic.
