Bhutiani N, et al. - In patients with extrahepatic hilar cholangiocarcinoma, researchers determine the impact of caudate resection on margin status and outcomes during resection. Caudate resection is associated with a greater likelihood of margin-negative resection among these patients. Researchers emphasize the criticality of precise preoperative imaging to assess the extent of biliary involvement so that all degrees of hepatic resections are possible at the time of the initial operation.
