Always remember you are entitled to a second opinion. If you are ever unsure, get many second opinions and not from forums like these but from qualified and experienced professionals who have access to all your medical notes and results.
If this annoys or worries the guy who initially recommends the procedure, then run away very fast.
Every medical professional should be comfortable with second opinions. Where are you located in the world? It may mean you have to travel some but as Celeste will tell you, she canceled this months mortgage payment, bundled Jerry into the old van and drove 3,000 miles to get an expert opinion. I think she still says it was the best move she ever made.
That pancreatitis is rare to very rare, that means that panc practitioners may not see that many cases per year. I had my condition reviewed in Liverpool Uni, UK, remotely. They showed them the CTs, blood work, and write ups from our professionals. They don't need to have the patient present to read xrays and other results.
Where your health is concerned, in fact your life and death is concerned, surely talking to two or three other panc specialists near you is worth the effort, isn't it?
Your call!
