[2] One study showed them originating from the liver parenchyma of the right anterior inferior dorsal subsegment or from the connective tissue of the gallbladder bed.
[9] As well, the exact origin and drainage locations of the relevant duct(s) varied greatly between patients.
The origin and drainage of these ducts were limited primarily to the right lobe of the liver, but great variation was seen.Although they may not drain any liver parenchyma, they can be a source of a bile leak or biliary peritonitis after cholecystectomy in both adults and children.
If an accessory bile duct goes unrecognized at the time of the gallbladder removal, 5–7 days post-operative the patient will develop bile peritonitis,[10] an easily treatable complication with a morbidity rate of 44% if left untreated.
[11] The term is named after German anatomist Hubert von Luschka (1820-1875)[12][13] who described the first case in 1863.
