抄録

We analyzed 167 cases with choledochocele reported in the literature, and tried to make the diagnostic criteria of choledochocele as follows.<BR>Choledochocele is a cystic dilatation of the intraduodenal portion of the distal bile duct. In many cases, it is a cystic dilatation of ampullary bile duct or common channel. It sometimes protrudes into the duodenum depending upon its size. Its maximal diameter should be bigger than 1cm. The histology of the lining epithelium of the choledochocele is not significant. Though its etiology is congenital or acquired, cases with impacted bile duct stone, or changes after endoscopic sphincterotomy or extraction of biliary stone should be excluded. It may be associated with pancreaticobiliary maljunction. In choledochocele forming common channel, we should note the occurrence of the biliary carcinoma, due to reflux of pancreatic juice into the bile duct.
