| Anatomical terminology |
An accessory bile duct is a conduit that transports bile and is considered to be supernumerary or auxiliary to the biliary tree.[8]
It may be described by its location relative to the gallbladder as supravesicular[2][3] (superior to the gallbladder body) or subvesicular[4][5] (inferior to the gallbladder body).
Duct of Luschka
In the surgical literature, the term duct of Luschka is used to refer to an accessory bile duct that does not communicate with the gallbladder lumen. The term is named after German anatomist Hubert von Luschka (1820-1875).[9] Accessory cystic ducts are excluded from the definition of duct of Luschka; however, they are accessory bile ducts.
The term duct of Luschka is ambiguous, as it may refer to supravesicular[2][3] or subvesicular ducts.[4][5] Supravesicular ducts are typically in the gallbladder bed. A 2012 review suggested that the term duct of Luschka should be abandoned because of this ambiguity and replaced by the more specific term subvesical bile duct.[7] As well, the exact origin and drainage locations of the relevant duct(s) varied greatly between patients.
Of 116 articles, 54 provided detailed anatomic information identifying 238 subvesical ducts, most of which represented accessory ducts. The origin and drainage of these ducts were limited primarily to the right lobe of the liver, but great variation was seen.
— -Schnelldorfer et al., [7]
Clinical significance
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,[citation needed] an easily treatable complication with a morbidity rate of 44% if left untreated.
Often diagnosed by HIDA scan, a bile leak from an accessory bile duct post-op can be treated with a temporary biliary stent[citation needed] to redirect the bile from the liver into the intestine and allow the accessory duct to spontaneously seal itself.
Eponym
The duct of Luschka is named after German anatomist Hubert von Luschka (1820-1875)[10]
