Upper Transversal Hepatectomy with Two Hepatic Veins Reconstruction: Combining Parenchymal-Sparing Liver Surgery with Transplantation Techniques for Colorectal Liver Metastases

Summary: This study verified the feasibility of liver resection with double hepatic vein (HV) resection and direct reconstruction for patients with colorectal liver metastases (CRLM) involving two adjacent HVs at the hepatocaval confluence. The results showed that all patients had patent HVs and were alive and in good condition after a median follow-up of 18 months. This surgical approach may guarantee oncological radicality and spare healthy parenchyma.
