“…[36][37][38][39][40][41][42][43] Again, the comparison of biliary remnants from inv mice to human infants with BA is not ideal, because the former are probably seen much earlier in the evolution of the lesion and without any inflammatory changes, and the latter are almost always at end-stage with marked inflammation and obliteration. There are rare patients with other anomalies of the extrahepatic bile ducts, including stenosis and duplication, [53][54][55][56][57][58][59] and even several patients with such anomalies in association with situs inversus. 60 However, all of these lesions were detectable at the gross level, whereas the accessory duct structures in the inv mice are only detectable at the histological level.…”

Extrahepatic biliary atresia (BA) is a devastating disease of the neonate in which the hepatic and/or common bile duct is obliterated or interrupted. Infants and children with this diagnosis constitute 50% to 60% of the pediatric population that undergoes orthotopic liver transplantation. However, there is still very little known about the etiology and pathogenesis of BA. Several recent studies have demonstrated that anomalies of situs determination are more commonly associated with BA than previously recognized. In this study, we examined the pathogenesis of jaundice in the inv mouse, a transgenic mouse in which a recessive deletion of the inversin gene results in situs inversus and jaundice. The results show that these mice have cholestasis with conjugated hyperbilirubinemia, failure to excrete technetium-labeled mebrofenin from the liver into the small intestine, lack of continuity between the extrahepatic biliary tree and the small intestine as demonstrated by Trypan blue cholangiography, and a liver histological picture indicative of extrahepatic biliary obstruction with negligible inflammation/necrosis within the hepatic parenchyma. Lectin histochemical staining of biliary epithelial cells in serial sections suggests the presence of several different anomalies in the architecture of the extrahepatic biliary system. These results suggest that the inversin gene plays an essential role in the morphogenesis of the hepatobiliary system and raise the possibility that alterations in the human orthologue of inversin account for some of the cases of BA in which there are also anomalies of situs determination.

“…The bile duct draining the caudate lobe usually joins the origin of the left or right hepatic duct. 27 The cystic duct typically joins the common hepatic duct below the confluence of the right and left hepatic ducts. This normal biliary anatomy is thought to be present in 58% of the population.…”

“…This normal biliary anatomy is thought to be present in 58% of the population. 26,27 The most common anatomic variants in the branching of the biliary tree involve the right posterior duct and its fusion with the left hepatic duct, which can occur in 13% to 19% of the population, 27,28 or with the right aspect of the right anterior duct 27,28 (Fig. 3).…”

This article discusses the rationale behind living (related) donor liver transplantation, the role of imaging in the preoperative evaluation of the potential donor, and the currently available imaging modalities for fulfilling this task. Furthermore, the normal hepatic vascular and biliary anatomy, as seen on imaging, is reviewed and the most common anomalies are highlighted. Finally, critical concepts in the diagnostic evaluation of a donor are discussed with special emphasis on how to accurately measure liver volumes. (Liver Transpl 2003;9:S6-S14.)

“…Among those cases, the cystic duct inserts into the middle third of the extrahepatic bile duct in 75% of cases and into the distal third in 10% of cases. Five types of cystic duct anomaly have been described: a long cystic duct with low fusion with the CHD, abnormally high fusion between a cystic duct and the CHD, accessory hepatic duct, cystic duct entering the right hepatic duct, and cholecystohepatic duct [6][7][8] . In particular, low medial insertion of the cystic duct deserves special attention, because this anatomical variant may lead to misdiagnosis by imaging studies, thus adversely affecting therapeutic intervention.…”

Mirizzi syndrome in an anomalous cystic duct: A case report

Mirizzi syndrome is a rare complication of gallstone disease, and results in partial obstruction of the common bile duct or a cholecystobiliary fistula. Moreover, congenital anatomical variants of the cystic duct are common, occurring in 18%-23% of cases, but Mirizzi syndrome underlying an anomalous cystic duct is an important clinical consideration. Here, we present an unusual case of typeⅠMirizzi syndrome with an uncommon anomalous cystic duct, namely, a low lateral insertion of the cystic duct with a common sheath of cystic duct and common bile duct.
