Amylase level in extrahepatic bile duct in adult patients with choledochal cyst plus anomalous pancreatico-biliary ductal union

Figure 2 Correlation between the age of symptomatic onset and bile duct amylase (n = 11) or gall bladder amylase (n = 10). A: There was highly significant correlation between age and level of amylase in bile duct; that is, the level of biliary amylase decreased with increasing age of onset (r = –0.982, P<0.01); B: in gall bladder (r = –0.636, P<0.05).
