Ducts of Luschka

The ducts of Luschka (also called supravesicular ducts) are small bile ducts in the posterior wall of the gallbladder (the gallbladder bed), some connected to a subsegmental area of the liver with bile ducts but none connected with the lumen of the gallbladder; they may be aberrant bile ducts. Although usually they do not drain any liver parenchyma, they can be a source of bile leak or biliary peritonitis after cholecystectomy in both adults and children.
