If you google LIFT procedure for fistula it will explain it a little better but my surgeon basically said it doesnt cut through the inner and outer muscles (risking incotenence ) but between the two muscles. Seems like its worth a try! He said if it doesn't work you just still have a fistula. Rachel- I've had mine for about 2 months and it is quite annoying! I feel like I would like to try SOMETHING to to fix it!!
