Central hepatectomy with pancreatoduodenectomy for diffusely spread bile duct cancer

Major hepatectomy with concomitant pancreatoduodenectomy (major‐HPD) is the only procedure that provides a curative resection for diffusely spread extrahepatic bile duct cancer (DSEBDC). We sometimes encounter patients who cannot undergo major‐HPD because of a poor functional hepatic reserve. The aim of the present study was to assess the feasibility of central hepatectomy with pancreatoduodenectomy (central‐HPD) for patients with DSEBDC as an alternative to major‐HPD.
