I had all of the same tests done due to elevated liver enzymes and actually got pancreatitis as a complication from the ERCP. Let me just say that I've been in pain before but NOTHING like the pain that night, which put me in the ER and then admitted to the hospital with no food or drink for 4 days. I vomited 28 times that night, and I'm not normally one to throw up. My amylase and liplase (sp?) were through the roof. So, it is very possible it could be pancreatitis if your numbers are up and if you start vomiting on top of it all, go to the ER.
