When I hear a statement like that "he had been doing this for 25yrs and a splenectomy was the best treatment", it makes me wonder how many ITP patients he's treated in those 25 years. I wonder how many different treatments he's tried on his patients - a few or all of them? I wonder if he ever followed up on those patients to see if they had any complications due to the splenectomy. That is a very broad statement.
I'm sure there are many people who have it done and live perfectly normal lives. But I always wondered what would happen if I ever developed cancer and had to do chemo and became very immunosuppressed, how much more dangerous would that be without a spleen? I wondered what would happen if I developed another autoimmune disorder (which I did) and had to be on immunosuppressants without a spleen? I wondered what would happen if I ended up with APS antibodies (which I did) and had more of a clotting risk without a spleen? I tried to think about problems down the road instead of just dealing with ITP now and getting it over with. ITP wasn't my biggest fear...it was being left spleenless with a more difficult problem that scared me. Having ITP can get old pretty fast. It invades your life and sometimes takes over. But - only if you let it. Looking around at other people who deal with things that are much worse made me realize that ITP is not that bad, especially if counts go up with treatment. I'm amazed at people like Michael J. Fox who endure horrible disorders and still walk around smiling. It takes an awful lot to inspire me but he does. I've also been inspired by people like Steve (who you've probably not met yet). He has had ITP nearly his entire life and has had three brain bleeds, but he'll be the first to tell you to ITP isn't the worst thing that can happen. His counts do not respond to anything, including splenectomy. I've seen people with ITP and AIHA, people with TTP and people with ITP and APS - those can be quite a balancing act and can make ITP seem like a walk in the park.
Sorry, I didn't intend to say all of that when I started this. It's just that I've had people spin my perspective on this in the past and it really helped. We used to post threads on the positive aspects of ITP and haven't done that in a while. So many people can come up with good stories...about special people they've met because of ITP, about how their attitude has changed because of ITP, etc. None of this has anything to do with your original question, but may help in the decision overall. If you do decide to do it, we'll all cheer you on and wish you the best. Everyone has to do what is best for them in the long run, whatever that may be. Your best bet for now is to ask questions, research and take one day at a time.
