I have been looking into tubal surgery myself Lauren for similar reasons plus adhesions. Yeah I think it does depend on the severity as to what they can do to save the tube/s. With any tubal surgery the risk of an ectopic pregnancy is fairly high. Other then reversing tubal ligations and repairing ectopic pregnancy it seems to be something not done very often so hard to get information on. One thing I was told unblocking blocked tubes because of infection they often stick back together again shortly after the repair. If it is from an infection sometimes antibiotics will clear the infection and make the tubes patent again. This isn't always the case though and depends how long the infection has been there for. Are you seeing a FS about this or a Gyno? I have been seeing a Gyno but am going to see a FS who's area of specilty is tubal problems. Hopefully he can provide some better info on it.
