【Abstract】ObjectiveTo investigate the anatomic feature and special clinical manifestations of variant right intrahepatic bile duct draining into left hepatic bile duct near the umbilical portion.
MethodsVariant right intrahepatic bile ducts joining into left hepatic bile ducts near the umbilical portions were identified through cholangiograms in 52 patients, who were included in this study. Their history, clinical process and operations were reviewed.
ResultsThere were total 38 cases of intrahepatic gallstone in this group. High incidence of intrahepatic calculi was found in variant right intrahepatic bile ducts （23/38 cases, 60.52%） and left hepatic ducts （33/38 cases, 86.84%）. Most of these cases were accompanied with dilatation and stricture of bile ducts in these area. The gallstones in the variant right intrahepatic bile ducts were not detected in 8 cases (8/23) and the rate of residual gallstone was as high as 86.95%(20/23). Injury of variant right intrahepatic bile duct took place when left hepatectomy was performed in one case.
ConclusionGallstone is very likely to be formed in the variant right intrahepatic bile duct due to derangement of bile hydrokinetics and compression of blood vessel. Special attention should be paid to the diagnosis and operation of this abnormity.
