Core Tip
Core tip: Right-sided ligamentum teres (RSLT) is a congenital anomaly that involves anomalous ramifications of the hepatic vessels and biliary system. A male in his 70s with RSLT was diagnosed with advanced gallbladder cancer directly infiltrating the right hepatic duct (RHD). Based on preoperative liver simulation, we successfully performed a modified right-sided hepatectomy sparing segment 8, which corresponded to resection of the RHD drainage territory (segments 1r, S5, S6, and S7), with negative surgical margins. This report is the first to describe major hepatectomy for advanced gallbladder cancer with RSLT.
