Prognostic value of positive surgical margins after resection of cholangiocarcinorna. Experience at a high-volume hospital center specializing in hepatopancreatobiliary surgery

Introduction and aims: Cholangiocarcinoma accounts for 3% of gastrointestinal tumors and is the second most frequent hepatic neoplasia after hepatocellular carcinoma. The primary aim was to evaluate the median disease-free period and survival in patients with cholangiocarcinorna diagnosis through the comparison of R0 and R1 resection margins.
