 Precise diagnosis of hepatolithiasis before surgery has become possible by recent advance of diagnostic modalities for direct cholangiography such as percutaneous transhepatic cholangiography (PTC) and endoscopic retrograde cholangiography (ERC). Furthermore, it has been clarified by the development of real-time ultrasound (US) that both of conventional PTC and ERC have difficulty in visualizing the entire feature of the intrahepatic biliary tree in patients with stenotic portion at the distal end of the segmentally dilated bile duct containing stones.

 The purpose of this paper was to assess the current diagnosis of hepatolithiasis based on our classification. According to our cholangiographic study, this condition was divided into two groups, primary (Fig. 1) and secondary (Fig. 2). The clinical and cholangiographic characteristics of each group were summarized in Table 1. According to the location of intrahepatic gallstones with associated segmental dilatation of the intrahepatic bile ducts, primary hepatolithiasis was divided into two subgroups: the type of the major intrahepatic bile duct (Figs. 4 and 5) in which the lesion was locating predominantly in the major hepatic ducts, and the type of peripheral intrahepatic bile ducts (Fig. 7) in which the lesion was distributed only in the smaller branches of the hepatic ducts at the third order branches or more proximal. The rate of incidence of the type of peripheral intrahepatic bile ducts, which had the mildest clinical features (Tables 3 and 4), has remarkably increased after the introduction of real-time US.

 The diagnostic capability of various modalities in detecting intrahepatic gallstones was studied in 28 patients (Table 6). Deffinite diagnosis of intrahepatic gallstones was made in 46.5% by PTC and/or ERC, 96.4% by US, and 100% by US-guided PTC, respectively.

 It was concluded that US was the most reliable modality in screening intrahepatic gallstones, and that US-guided PTC was the most accurate procedure to give the precise diagnosis in patients with insufficient informations by ERC (Fig. 7).
