According to the results, we performed pancreaticoduodenectomy, perihilar hepatectomy, neoplasty of high bile duct, partial resection and repair of the main portal vein, partial resection and repair of the right portal vein, repair of the right hepatic artery, and reconstruction of the digestive tract (Figure 2).
The surgical specimen showed that the tumor was a well-delineated solitary mass, and that the actual size was ~17 x 12 cm. The section of the tumor showed a pale and solid mass, which is relatively tough.
