Abstract:
Objective To investigate the relationship between occult pancreaticobiliary reflux (OPR) and biliary diseases.Methods Forty-four patients with primary biliary diseases was enrolled,and serum amylase level was determined,and the bile in common bile duct (CBD) was collected to measure the amylase level,then the △ amylase was calculated,which equals bile amylase level minus serum amylase level.OPR was confirmed if bile amylase level was higher than serum amylase level,otherwise it would be defined as the control group.Results Among the 44 patients with primary biliary diseases,the incidence of OPR was 72.7％ (n =32).The bile and serum amylase activity of patients with OPR were (1 513 ± 2 725),(44 ± 21)U/L;and they were (18 ± 14) and (38 ± 17) U/L in the control group.The bile amylase level in OPR group was significantly higher than that in the control group,and the difference was statistically significant (P ＜ 0.05),while there was no significant difference in serum amylase activity between the two groups.The incidence of OPR in patients with CBD stones was 100％,and the bile amylase activity was (1 048 ± 1 317) IU/L,and the △ bile amylase activity was (996 ± 1 322) U/L;the incidence of OPR in patients with choledocholithiasis and cholecystolithiasis was 75％,and the bile amylase activity was (2 457 ± 3 312),the △ amylase activity was (2 412 ± 3 320)IU/L;and the corresponding values in patients with gallbladder stones were 80％,(95 ± 82),(57 ± 76)IU/L;and the corresponding values in patients with bile duct cancer were 50％,(73 ± 51),(40 ± 37)U/L.Conclusions The occurrence of OPR is closely related to CBD stones only,CBD stones and gallbladder stones,and it may be one of the main pathogenic factors of bile duct stones.
