[A rare case of gallbladder interposition in the extrahepatic bile ducts].

This is a report on an exclusively rarely met with anomaly, consisting in interposition of the gallbladder within the extrahepatic bile ducts where ducti hepatici open into the gallbladder. Ductus cysticus assumes the role of ductus choledochus, and terminates in papilla duodeni major. Ductus hepaticus communis is completely lacking. The aforementioned anomaly of the biliary system in the female patient reported on is supplemented by a vascular variation, consisting in the following: a. hepatica dex. passes over the isthmus of the gallbladder, and after forming a kink it is directed to hilus hepatis. At the apex of the kink a. cystica divides with blood supply being secured by the latter and the branches of a. hepatica dex. A similar anomaly is described by Nell Krug (2), whereas J. Denes (1) reports on a case where only ductus hepaticus dex. opens into the gallbladder.
