I've heard that an inexperienced doctor can cause that kind of damage.
Ask your doctor how many he has done. Less than 100 is not enough experience in my book.
My doctor has done over 130 of them and teaches other how to do it. His own nurse has trusted him to do her 17 yr. old daughter's procedure. He will take out of town or out of state patients. He tries to get everything (preop, his own endo, and the surgery) all within one week. (Dr. Vito John Bagnato, Albany, GA)
My Esophyx surgery is scheduled on my next holiday in Dec. I'm not worried.
