carma, thanks i really appreciate that-i wish i had found out before the op too. Thats why i set it up to inform us all. Keep up your hope,if you want some info, just do some research to assure you. There is plenty out there. I'll pray that the doctor you get will do the job right. Ask him plenty of questions, how he performs it, how many he has done, when was the last one he perform, what he does for follow up. Drill Him!
