Pancreatitis is the most likely reason, as the lipase tends to be a more specific test. The amylase level tends to fall sooner, and the lipase may take a bit more time before going down.
Kidney disease, bowel obstruction, and peptic ulcer disease can also raise the levels, but not often to that degree.
Further tests, including an MRCP or ERCP to evaluate the cause of the pancreatitis can be considered.
