UNASSIGNED: To determine the causes underlying the formation of adult @entity2941 .Anomalous pancreaticobiliary junction is the most widely accepted theory regarding the etiology of @entity2941 . However, @entity2941 have been found in @entity1 in the absence of this @entity154 . Because the number of adult @entity1 with @entity2941 is increasing, it is important to address this controversy.Bile amylase levels in the cysts of 27 @entity1 (8 males and 19 females) who had undergone cholecystectomy were retrospectively evaluated.The average age of the 27 @entity1 was 45.8  10.1 years and the majority (85.2%) were diagnosed with Todani type I cysts. None of the @entity1 had dilatation of the common bile duct prior to surgery. There were 6 (22.2%) @entity1 with @entity3161 . However, amylase levels did not significantly differ between @entity1 with and without this @entity154 (P=0.251). According to bile amylase levels, @entity354 was present in 21 (77.8%) @entity1 . The mean amylase level significantly differed in @entity1 with @entity354 (23,462  11,510IU/L) and those without (235  103IU/L) (P<0.001). In @entity1 with @entity354 , only 4 @entity1 had @entity3161 . That is, the majority of @entity1 (17/21, 81%) having @entity354 did not have an anomalous junction of the pancreatic and biliary ducts.Since the only explanation for @entity354 in @entity1 with a normal pancreaticobiliary junction is @entity1690 , we proposed that the formation of adult @entity2941 is mainly due to @entity1690 .
