Dear Pamela,
Depending on whether or not you feel comfortable and depending on the size and location and the surgery type.Hmmmm....It would be hard to say.....I can only say that both Dr. Kondzuilka and Dr.Sisti agreed on surgery in my case in 2004. The best advice I can give is get the opinion of another doctor and then pray on it.
I know this may not be the answer you expected, but in your case I don't know. If Dr.Sisti says you should watch and wait it's probably because he doesn't do surgery with tumors below a certain size. However if you feel more at ease with surgery performed by Dr.Konzuilka and he has discussed all the pluses and minuses of it. Then go for it.
I highly recommend interviewing 3 docs with the same approach, however.
As you probably already know, there are certain things that you will have as a result of surgery that you don't have with Gamma Knife. Gamma Knife surgery is not surgery at all and only involves one shot radiation (and only involves an outpatient stay involving a head frame that has to be screwed onto your head (don't worry the holes fade).
Had that option been offered to me(Gamma Knife) I would have taken it over the surgery.
In fact I was considering Gamma Knife (with another doctor in New Hampshire) but the targeting method used wasn't exact in my case (CT instead of MRI due to an inability to have an MRI because of preexiting clips from my other surgery (see below) So I went back and did the surgery with Sisti.
Whatever you do, you would be wise to do the due diligence of the research. Whichever you choose these are my two top docs, you will find that you will be pleased with the results.
They have the experience of doing hundreds of similar cases.
You have a tough choice ahead of you, good luck I will be praying for you. Come back often or PM me.
Your friend,
Mike
