Serial changes in serum amylase (mean and SE values) before and after ERCP in the nafamostat- and gabexate-treated groups. The mean 6-h post-ERCP serum amylase level of the gabexate-treated group was significantly higher than that of the nafamostat-treated group; however, the mean post-ERCP amylase level did not differ significantly between the two groups thereafter. The overall post-ERCP amylase levels in the two groups did not differ up to 36 h after ERCP (repeated-measures analysis of variance, p=0.296).
