Abstract Treatment of the bile ducts at the porta hepatis is a critical step for avoiding post-surgical bile leakage and atrophy of the residual liver and/or the graft during hepatobiliary surgeries, such as hemihepatectomy, surgeries for cholangiocarcinoma or procurement of graft. Precise knowledge of the bile duct anatomy in individual cases has great importance in avoiding these kinds of complications. According to the Couinaud nomenclature, the intrahepatic biliary system can be divided into eight segments: the right anterior hepatic lobe (S5, S8), the right posterior lobe (S6,S7), the left liver (S2-4), and the caudate lobe (S1). The incidence of this normal anatomy was reported in 40%–80% cases [1]. Numerous intrahepatic biliary variations have been reported [2–4]. However, the data for the Chinese population are paucity.
