With the steady improvement in diagnostic modalities and increasing numbers of hepatic malignancies, tumors originating in caudate lobe can be detected while at a respectable stage, when resection of the caudate lobe is required for tumor clearance. The operation may be an isolated caudate lobe resection or a caudate lobe resection combined with a major hepatectomy; caudate lobectomy is thus classified into isolated and combined resections. It is also classified into complete and partial resections. Thus, caudate lobectomy can be classified into four types: isolated complete resection, combined complete resection, isolated partial resection, and combined partial resection.
