The impact of caudate lobe resection on margin status and outcomes in patients with hilar cholangiocarcinoma: a multi-institutional analysis from the US Extrahepatic Biliary Malignancy Consortium

Precise preoperative imaging is critical to assess the extent of biliary involvement, so that all degrees of hepatic resections are possible at the time of the initial operation.
