The prognosis of hilar bile duct cancer has been improved by extensive curative resection, but massive hepatectomy can result in surgical and medical complications in high-risk patients. We report a case of type IIIb hilar bile duct cancer undergone S4a+S5 with caudate lobe (S1) resection as a parenchyma-preserving hepatectomy. The operation was a modified type of Taj Mahal liver resection omitting parencymal transection between S4b and S8. Such an extent of hepa- tectomy combined with bile duct resection made 3 right and 3 left intrahepatic segmental duct openings, which were reconstructed as a whole at each side of transection plane after ductoplasty. The patient recovered uneventfully. Although surgical technique for S4a+S5+S1 must be more complex comparing with other anatomical hepatectomy, but it could be accepted as a safe curative resection for some selected patients with advanced hilar bile duct cancer, by which favorable recovery of the liver function may lead to pre- vention of postoperative complications. Comprehension to the anatomy of the intrahepatic ducts is a prerequisite for S4a+S5+S1 resection, thus we discussed it in detail. (J Korean Surg Soc 2003;64:515-520)
