Introduction : Laparoscopic donor right hepatectomy (LDRH) is an innovative procedure in the field of living donor liver transplantation. Recently, we performed pure LDRH in a living donor with the accessory segment 8 bile duct (accessory B8) opening to the left hepatic duct.

Methods : On preoperative magnetic resonance cholangiopancreatography (MRCP) of A 25-year-old healthy male , right hepatic duct (RHD) was bifurcated with left hepatic duct at the extrahepatic level, and closely located with cystic duct.

Results : The operation began with full mobilization of the right hemi-liver. After cystic duct and artery were divided, hilar dissection was performed. Right portal vein (RPV) and right hepatic artery (RHA) were identified and then clamped temporarily to check the transection plane demarcated on the liver surface. After hepatic parenchymal transection and caudate division, right side of the hilar plate was encircled. Extrahepatic bifurcated right hepatic duct.was divided at the upper confluence level of cystic duct. After Encircled right hilar plate was divided with scissors, accessory B8 was identified, 2mm-sized. RHA and RPV were ligated using the Hem-o-lock. Right hepatic vein was transected by unilateral linear staplers. The operation time to retrieval of the graft was 290 minutes. In bile duct anastomosis of the recipient, Accessory B8 was sacrificed, and RHD of graft was anastomosed with common hepatic duct of recipient. Both donor and recipient had no complication.

Conclusions : In the present case, pure LDRH for a living donor with complex bile duct anatomy was safe and feasible approach for experienced surgeons. .
