Thank you for your question.
I am Dr. Su S. and I will try my best to help you.
From your description it seems that there should not be any problem during travelling.
However you can make an appointment with local pediatric surgeon before travelling
He can guide you better about the risk after examining him.
The links below can help you to know about the pediatric surgeons in Orlando.
You can contact them.
This is the link of one doctor.
You can choose any other of the list too.
I hope this information will be helpful.
If you have any query, please feel free to ask.
Wish him healthy life.
