Intraoperative assessment of the resectability of hilar cholangiocarcinoma. | LitMetric

AI Article Synopsis

Article Abstract

Major hepatectomy combined with extrahepatic bile duct resection has gained acceptance as a standard radical procedure for hilar cholangiocarcinoma. Here, we describe an operative technique, "taping of the right hepatic artery behind Calot's triangle", for assessing the resectability of hilar lesions for which left-sided hepatectomy is planned. Briefly, after retracting the gall-bladder anteriorly, the lateral peritoneum of the hepatoduodenal ligament is incised longitudinally (3-4cm in length) behind Calot's triangle and just to the left of the fissure of Ganz. By dividing the adipose tissue, the distal portion of the right hepatic artery is identified and secured with tape. Any suspicious tissues around the right hepatic artery should be submitted to frozen-section analysis. If no cancer cells were found, the planned resection goes ahead. Conversely, if they were found, the resection should be abandoned. Since 2003, 14 patients for whom left-sided hepatectomy was planned for hilar cholangio-carcinoma involvement, underwent this technique. Three patients were judged to have irresectable tumors and the planned resection could be avoided. In conclusion, this simple technique, isolation of the right hepatic artery behind Calot's triangle before starting resection, should be applied to all hilar malignancies when a left-sided hepatectomy is planned.
