It is likely an ERCP was performed to remove the stone from the bile duct. An elevation of amylase is common after this procedure, occuring in about 70 percent of patients. There is also the possibility of elevated liver enzymes due to the procedure as well. The fact that it has decreased is reassuring.
I would continue to recheck these enzymes serially to ensure the continue to fall. If they start to rise again, despite a longer period of time post-procedure, you may then want to consider further testing and a referral to a more specialized facility.
Followup with your personal physician is essential.
