I have had a fistula for a year. I went to my surgeon in Atlanta Friday after seeing several Drs local that were clueless. He put a seton in and told me to go to Dr David Beck in New Orleans and he will do a martius flap, the mesh does not work. Not many docs do Martius, Dr Hull at CCF Ohio and Dr Remzi there both do but with ostomy which I will not be required to do.
