Double Mini Upper Transversal Hepatectomy for Colorectal Liver Metastases Infiltrating the Right and the Left Hepatic Veins at the Hepatocaval Confluence

The authors investigate the feasibility and outcomes of a novel surgical technique, double mini upper transversal hepatectomy, for patients with colorectal liver metastases infiltrating both the right and left hepatic veins at the caval confluence, traditionally deemed unresectable. They present a case where the presence of peripheral communicating veins allowed for successful tumor resection while preserving venous outflow, leading to a positive postoperative outcome without major complications. This study suggests that parenchyma-sparing strategies can achieve oncologic radicality in complex liver resections.
