Accessory Duct of Luschka

"A common anomaly of the biliary system is the existence of a small bile duct that leaves the right lobe of the liver and runs in the gall bladder bed (i.e., in the subvesicular connective tissue between the gall bladder and the liver) to reach the right hepatic or common hepatic bile duct. This "duct of Luschka" can be injured in cholecystectomy. Also, there may be tiny bile ductuli that leave the liver substance to end blindly in the subvesicular connective tissue. These are a source of self-limiting bile leakage following a cholecystectomy"1.
