i don't know lista specifically, you could put his name into this site's search engine and see if he's been discussed. a p.s. who advertises on the radio might not be my first choice, just as my first choice for a lawyer might not be the guy on the back of the phone book, i'd want to know how many gyne ops a year he does. if it's less than, i don't know, two or three dozen or something, gyne's probably not really a specialty of his, though maybe it is. either way, take comparison shopping more seriously than if you were just buying a car, talk to at least 2 or 3 dr's.
the medical risks are not zero, but they never are from the minute you set foot in any medical facility, they are probably much better than if you were having something more serious like an appendectomy, and even operations like that are somewhat routine. if it's a serious concern, you can always raise it after the other more important questions when you're interviewing/consulting with someone.
