Open Parenchymal Sparing Posterosuperior Liver Tumor Resection for Colorectal Liver Metastasis With Proximity to Hepatic Veins.

Liver resection for stage 4 colorectal cancer with liver metastasis is the standard of care, in combination with systemic chemotherapy. R-0 complete resection for colorectal liver metastasis is a curative-intent operation, which is considered the only chance for cure in this disease. The location and proximity of the tumor to major intrahepatic vessels such as hepatic and portal vein determine technical difficulty. Tumors located in the posterosuperior segments of the liver (segments 7 and 8) are technically challenging to resect using a minimally invasive fashion; therefore, conventional open resection is still the technique of choice today. In this video, we demonstrated our approach of an open parenchymal-sparing posterosuperior liver resection for a colorectal liver metastasis.
