Total upper transversal hepatectomy with outflow reconstruction for advanced mass-forming cholangiocarcinoma

We describe a complex case of extended hepatectomy with venous outflow reconstruction for the treatment of advanced mass-forming cholangiocarcinoma (MFCCC) invading the three main hepatic veins (HVs). A 50-year-old woman who received a diagnosis of MFCCC and judged unresectable, was referred to our hospital. After multidisciplinary team evaluation, the patient underwent abdominal computed tomography, gadoxetic acid-enhanced magnetic resonance imaging, and fluorodeoxyglucose positron emission tomography. The radiological examinations showed a large mass located in S4s-8 and S1, in contact with the right hepatic vein (RHV), the inferior right hepatic vein, the anterior wall of the inferior vena cava (IVC), infiltrating the middle and left hepatic veins (MHV, LHV). Several communicating veins between the RHV, MHV and LHV were detected. The case was further investigated, and the surgical strategy planned by means of using three-dimensional simulation software. A total upper transversal hepatectomy with resection of the main HVs and outflow reconstruction was performed. The outflow of the remnant liver was restored performing a vascular anastomosis between the parenchymal stump of the RHV and the IVC. Meticulous review of pre-operative imaging techniques with three-dimensional simulation of hepatectomy together with advanced use of intra-operative ultrasound allowed us to offer the chance of cure to a patient otherwise considered unresectable.
