Successful Parenchyma-Sparing Anatomical Surgery by 3-Dimensional Reconstruction of Hilar Cholangiocarcinoma Combined with Anatomic Variation.
2016
The combination of hilar cholangiocarcinoma and anatomic variation constitutes a rare and complicated condition. Precise understanding of 3-dimensional position of tumor in the intrahepatic structure in such cases is important for operation planning and navigation. We report a case of a 61-year woman presenting with hilar cholangiocarcinoma. Anatomic variation and tumor location were well depicted on preoperative multidetector computed tomography (MDCT) combined with 3-dimensional reconstruction as the right posterior segmental duct drained to left hepatic duct. The common hepatic duct, biliary confluence, right anterior segmental duct, and right anterior branch of portal vein were involved by the tumor (Bismuth IIIa). After carefully operation planning, we successfully performed a radical parenchyma-sparing anatomical surgery of hilar cholangiocarcinoma: Liver segmentectomy (segments 5 and 8) and caudate lobectomy. MDCT combined with 3-dimensional reconstruction is a reliable non-invasive modality for preoperative evaluation of hilar cholangiocarcinoma.
