Oh gosh, @momofjohn, I can imagine you are worried sick about your son. I'm not qualified to even guess why they have to wait before doing the splenectomy. Maybe they have to wait until he is stronger. Only your son's surgeon can explain why this is best in your son's specific case.

Are you or your son able to contact the surgeon to ask this very important follow-up question? Do you have an online patient portal where you/he could submit the question to his team?
