Summary

This study tests whether adding an oral medication (tacrolimus) before an ERCP procedure can prevent pancreatitis, a painful inflammation of the pancreas that sometimes occurs afterward. About 4,800 adults undergoing ERCP will be randomly assigned to receive either the standard rectal medication alone or the standard medication plus oral tacrolimus. The goal is to see if the combination reduces the number of people who develop pancreatitis after the procedure.
