I did 2 1/2 years ago at Cleveland Clinic. I still have minor leakage issues sometimes and constant irritation . Dr Remzi told me leakage could occur, and Dr shen says anal irritation is very common with redos. Wants me to do the hyperbaric oxygen chamber therapy. I don't have the money or the time to do that. Its every day for 2 hours for 60 days I think. Some of us work for a living..
